Cerebrospinal fistula might occur in different ways. CSF closure techniques have undergone significant evolution that has led to the consolidation of the transnasal endoscopic approach. Despite the existence of multiple publications, meaningful information is still lacking in clinical practice and the literature about the ideal method, material, and timing for repair of CSF. The purpose of this review was to summarize the success rate of endoscopic CSF leak repair as well as whether specific techniques or materials influence the primary success rate through a review of the latest advancements in endoscopic CSF management published in the past 10 years. The principles of multilayer reconstructions and the routine use of vascularized flaps in expanded endonasal surgery have reduced postoperative CSF leaks' failure rates between 5% and 10% (4% in this meta-analysis). Effective endoscopic anterior skull base (ASB) closure may be achieved by multiple reconstructive techniques, which should be tailored case by case according to the patient and defect conditions.

Investigate the incidence, the degree and the effect of gastro-pharyngeal reflux (GPR) in laryngectomised patients.Behavioral and 24-hour pH- and impedance-monitoring data were prospectively analyzed for 25 laryngectomised patients with no previous history of GER in outpateints' setting. Reflux detected was characterized as either acid, weakly acidic or nonacid. Proximal reflux was found at 15cm above the LES.40% of patients presented a pathological number of reflux episodes in the upright position (p0.0001); 9 of them presented a pathologic bolus exposure time. Bolus exposure at the proximal sphincter was one fourth-fold lower than 5cm above the LES (p=0.3593). There was a prevalence of acid reflux at both sphincters (p0.0001); liquid reflux was prevalent at the LES (p=0.003) and mixed reflux at the UES (p=0.0001). Median REs was higher than time acid exposure (p=0.0013).Pre- and post-surgical reflux investigation could identify preexisting reflux severity and screen potential high-risk cancer patients for postoperative complications. This might allow the early onset of acid suppressive therapy in presence of pathologic findings in high-complication risk cancer patients.

PURPOSE: The objectives of this meta-analysis were to summarize the key surgical procedures for UVCP and to evaluate which of these is associated with better results in terms of vocal improvement. METHODS: A systematic review of the literature was conducted in search of articles focused on the comparison of voice outcome between different techniques for the UVCP treatment. Then, a quantitative analysis was carried out for papers published from 2013 onwards, reporting only adult patients with unilateral paralysis for each study, and each surgical technique was evaluated for its capability of achieving good functional outcomes in terms of GRBAS-I scale and maximum phonation time in seconds (MPT). RESULTS: The search identified 1853 publications. A total of 159 articles were stratified and included according to our selection criteria. 21 out of 159 articles were selected for quantitative synthesis. For trans-oral techniques: the mean GRBAS-I scale were 2.33 before injection and 0.41 after injection. The mean MPT before injection were 4.78 and 12.50 after injection. For open techniques the mean GRBAS-I scale were 2.43 before surgery and 0.68 after surgery. For open technique, the mean MPT were 3.50 before surgery and 12.40 after surgery. CONCLUSIONS: The two types of techniques lead to an improvement in terms of vocal outcomes emphasizing that from the examined literature an indication emerges to perform an early injection because this could reduce the possible need for a more invasive intervention of permanent medialization in the future.

Objective:Olfactory dysfunction is a possible side effect of chemo-radiotherapy performed in patients affected by nasopharyngeal carcinoma. Self-rating measurements and olfactory event-related potentials were used and compared in order to evaluate the impact of this treatment on the olfactory system.Methods:Nine patients underwent subjective evaluation of olfactory function (using visual analogue scales for olfactory symptoms and quality of life, and a six-item Hyposmia Rating Scale), and a quantitative and objective measurement (olfactory event-related potentials).Results:Spearman's rank correlation analyses highlighted significant relationships between the clinical scales and olfactory event-related potentials. Inter-group analyses showed significant differences in the latency and in the amplitude of olfactory event-related potentials between patients and controls.Conclusion:Taking into account the small sample size and the lack of pre-treatment assessment, olfactory event-related potentials seemed to allow a more objective diagnosis of unilateral and bilateral olfactory loss. Moreover, olfactory event-related potentials and subjective scales results were concordant.

Liver transplantation is the ideal treatment for patients affected by early stage hepatocellular carcinoma and chronic liver disease. Considering organs shortage, alternative treatments have to be adopted to minimize the waitlist drop-out, and in case of recurrence within the accepted criteria, salvage transplantation can be considered. Surgical resection is one of the most effective treatments, with the possibility of oncological radicality and pathological analysis of the specimen. Although these theoretical advantages, surgical strategy cannot be applied to all patients because of the impaired liver function as well as the amount of parenchyma to be resected does not allow a sufficient future liver remnant. Furthermore, resection by laparotomy may lead to strong intra-abdominal adhesions in a contest of portal hypertension and, as potential consequence, increase transplantation difficulty raising morbidity. Laparoscopic liver resection is now performed as a routine procedure in tertiary referral centers, with increasing evidence of long-term results comparable to traditional surgery together with the advantages of a minimally invasive approach. In addition, with a salvage transplantation strategy that has been shown to be comparable to primary transplantation, the patient can live with his native liver avoiding an invasive procedure and long-term immunosuppression, allowing the use of liver grafts for the community. We present the results of an Italian multicenter experience of salvage liver transplantation following the recurrence of HCC initially treated by laparoscopic resection in 31 patients, performed by four referral centers. Mean operative transplantation time was 450min, morbidity was 41.9%, 90-days mortality was 3.2%, and median post-operative length of stay was 17.9days. Salvage liver transplantation after laparoscopic liver resection for HCC is comparable to open surgery in terms of operative time, oncologic radicality, morbidity and mortality, with the advantages of laparoscopic surgery.

Purpose Adenoid cystic carcinoma (ACC) is a uncommon salivary malignant tumor. Our aim was to review our experience with parotid ACC, to identify clinical-pathological parameters predictive for outcome. Materials and methods We retrospectively reviewed 228 patients affected by parotid gland carcinomas surgically treated at our Institution. Forty-four ACC were included in this study. Multivariate analysis risk models were built to predict recurrence free probability (RFP), distant recurrence free probability (DRFP), overall survival (OS) and disease free survival (DFS). Results Twenty-one patients (47.7%) died from ACC and 2.3% for other causes. The 41% presented local-regional recurrence, with a regional-RFP rate of 93%, and the 34% reported distant metastases (DM). The five and ten-year OS rates were 74% and 50%, respectively. Conclusions Recurrences were mainly influenced by the presence of perineural invasion and nerve paralysis, whilst female gender and age

Pancreaticoduodenectomy (PD) is associated with high postoperative morbidity. The management of postoperative complications is paramount for reducing the mortality rate. The aim of this study was to evaluate the importance of surgical and hospital experience on outcomes by comparing postoperative results in three different hospitals with increasing resources for supporting the same surgical team. Patients data and surgical outcome of 300 consecutive patients undergoing PD were collected prospectively in the department database and divided into three periods (A = 1990-2000, B = 2001-March 2007, C = April 2007-2015). Pancreatico-jejunostomy was the procedure of choice between 1995 and 2004, and pancreatico-gastrostomy was performed afterwards. In the periods A, B and C, a total of 78, 85 and 137 PD were performed, respectively, and the number of PDs per year increased from 5 to 25. Between the three periods, the death rate (10.4 vs. 6 vs. 1.6%, p = 0.01) and intraoperative RBC transfusion rate (84.9 vs. 42.4 vs. 6.5%, p = 0.01) decreased significantly, whereas the vascular resection rate increased significantly (1.2 vs. 7 vs. 14.5, p

BACKGROUND: Liver transplantation (LT) is a well-established procedure for hepatocellular carcinoma (HCC) within the Milan criteria. Yttrium-90 microspheres radioembolization (Y90-RE) has shown to be an effective and safe treatment of primary liver tumors. We retrospectively evaluate the efficacy of the Y90-RE in patients with HCC prior to LT. METHODS: From January 2002 to December 2015, 365 patients were transplanted at the San Camillo Hospital Center. One hundred forty-three patients were transplanted for HCC, and in 22 cases the patients were treated with Y90-RE before LT. RESULTS: Three patients were treated with Y90-RE within the Milan criteria, and 19 patients were out of criteria before Y90-RE. Four patients had an increasing MELD score between Y90-RE and LT. On the other hand, alpha-fetoprotein decreases after Y90-RE treatment in all cases. No patient death was observed in Y90-RE procedure or at LT. In 78.9 % of cases, a successful downstaging was observed, and in 100 % of cases bridging was achieved. From Y90-RE treatment overall survival was 43.9 months. From LT, overall mean survival was 30.2 months with a free survival of 29.6 months. The overall survival after LT analysis between the patients treated with Y90-RE and patients without was not significant (p = 0.113). Free survival analysis was not significant (p = 0.897) between the two populations. CONCLUSIONS: We successfully performed LT in patients after Y90-RE treatment both as bridging and downstaging for HCC and obtained a similar overall and free survival of LT for HCC within Milan criteria. Y90-RE becomes a real option to provide curative therapy for patients who traditionally are not considered eligible for surgery.

Liver surgery in patients with underlying liver disease results in higher mortality and morbidity rates compared to patients without underlying liver disease. Laparoscopy seems to have good results in patients with normal liver in terms of postoperative outcomes, but is more challenging in cirrhotic patients. Aim of this study was to evaluate the feasibility of laparoscopic liver resection both in normal and cirrhotic livers, and secondary endpoint was to compare the surgical results.We retrospectively evaluated 105 patients who underwent laparoscopic liver resection between November 2001 and January 2012. Candidates for laparoscopic liver resection were divided into two groups according to the presence or absence of an underlying liver disease.105 patients (52.4% males, median age 56.1 years) were enrolled, and 37.1% had liver cirrhosis. Hepatocellular carcinoma in hepatitis C virus-related cirrhosis (89.7%) and liver metastases (57.6%) were the main indications for surgery in patients with cirrhosis and non-cirrhotic livers, respectively. None of the patients died post-operatively. Cirrhotic patients had greater blood loss (100 vs 50 ml; p0.012) and longer hospital stays (6 vs 4 days; p0.031) compared to non-cirrhotics.Laparoscopic liver resections are safe and feasible procedures in both patients with cirrhotic and non-cirrhotic livers.

The identification and surveillance of patients with liver dysfunctions and the discovering of new disease biomarkers are needed in the clinical practice. The aim of this study was to investigate on Survivin-immunoglobulin (Ig)M immune complex (IC) as a potential biomarker of chronic liver diseases.Serum levels of Survivin-IgM were measured using an enzyme-linked immunoassay that had been standardized and validated in our laboratory in 262 individuals, including healthy subjects and patients with chronic viral hepatitis, cirrhosis and hepatocellular carcinoma (HCC).Survivin-IgM IC was lower in healthy subjects (median, 99.39 AU/mL) than in patients with chronic viral hepatitis (median, 148.03 AU/mL; P = 0.002) or with cirrhosis (median, 371.00 AU/mL; P 0.001). Among patients with cirrhosis, those with hepatitis C virus (HCV) infection showed the highest level of Survivin-IgM IC (median, 633.71 AU/mL; P 0.001). The receiver-operator curve analysis revealed that Survivin-IgM accurately distinguishes HCV correlated cirrhosis from chronic viral hepatitis (area under the curve [AUC], 0.738; sensitivity, 74.5%; specificity, 70.7%). A multivariate logistic regression model, including Survivin-IgM IC, aspartate aminotransferase (AST) and AST/alanine aminotransferase (ALT) ratio increased the prediction accuracy for the identification of the cirrhotic HCV patients (AUC, 0.818; sensitivity, 87.2%; specificity, 65.9%). Conversely, Survivin-IgM IC significantly decreased in HCC patients (median, 165.72 AU/mL; P = 0.022).Our results suggest that Survivin-IgM immune complex may be used as a potential biomarker for liver damage, particularly for the identification of the HCV-related cirrhotic population.

This survey provides an overview about current spread of Minimally Invasive Liver Resection (MILR) in Italy. Primary endpoint was to assess evolution of MILR in recent years and its degree of application among centres with different experience in laparoscopic and hepatic surgery. A questionnaire with items describing activity MILR was sent to Italian surgical centers. Diagnosis, technical approaches, resection extent, devices and vascular control, reasons for conversion, morbidity and mortality were recorded. Level of expertise per centre was analysed in terms of learning curve acquisition and relationship with hepatobiliary background. 1497 MILRs from 39 centers (median 27 patients/center, range 1–145, period 1995–2012) were collected. Conversion rate was 10.7% (180 patients out of 1677, excluded from subsequent analysis), with bleeding representing most frequent cause of conversion (34.4%). Eleven centers completed learning curve, performing >60 MILR. Benign lesions were 27.5% and malignant 72.5%, with hepatocellular carcinoma being the most frequent indication. 92.6% of cases were performed with a totally laparoscopic technique (1.3% were hand-assisted, 1.9% single-port and 4.2% robotic). Minor resections accounted for 92.9% (left lateral sectionectomy resulted the most frequent procedure; 23.8%), while major resections represented 7.1%. Overall mortality was 0.2% (3 of 1497 patients) and morbidity 22.8%. Mean length of stay was 5days. Correlation between MILR activity and a hepatobiliary background was not clear comparing MILR cases and liver resection volumes per center. MILR has been significantly widespread in Italy in recent years, with several centers having definitely completed the learning curve as attested by clinical results consistent with major series from the Western and Eastern countries. MILR programs in Italy seem to arise from both centers with specific hepatobiliary expertise and centers performing advanced general laparoscopic surgery.

After failure of curative radiotherapy (RT), surgery is the main therapeutic option to control recurrent laryngeal cancer. Recurrences after RT for T1–T2 tumours of the glottic larynx are often diagnosed at a more severe stage than the original disease and, thus, usually treated by radical approaches. Our aim is to investigate the feasibility of more conservative strategies for proper treatment of post-RT recurred glottic cancer. We collected and reviewed our files from 1990 to 2006, selecting 75 patients which matched the following inclusion criteria: (1) patient was originally diagnosed with early stage squamous cell carcinoma of the glottic larynx (stage I–II according to 2010 TNM), (2) patient was treated by RT with curative intent, (3) patient presented a recurrence of disease after RT which was surgically treated at our Institution. T stage at first diagnosis was T1a in 41 cases (55 %), T1b in 12 (16 %) and T2 in 22 (29 %). At clinical examination of RT-recurred lesions, we documented advanced lesions (rT3–rT4) in 29 out of 75 patients (39 %). Overall, an upstage was reported for 56 % RT-recurred cancers, while 37.3 % remained at the same stage than the original tumour and 6.7 % were downstaged. Twelve patients (16 %) underwent salvage partial laryngectomy (SPL), while 63 (84 %) received a salvage total laryngectomy (STL). Multivariate analysis showed that rTNM according to the AJCC-UICC of 2010 was the only prognostic factor for both disease-free survival (p = 0.042) and overall survival (p = 0.004). Considering the prognostic impact of rT and rN we documented a statistical significance only in terms of overall survival for both factors (p = 0.004 and p = 0.04, respectively). Although STL remains the most frequent treatment choice for failures after RT in laryngeal carcinomas, SPL represents a valid option for selected patients with limited recurrence and can deliver good oncologic and functional results if performed according to careful indications.

In case of liver tumor, surgical resection is the therapeutic gold standard to increase patient survival. Among liver resections, right hepatectomy (RH) is defined as a major hepatectomy. The first aim of this study was to analyze the overall morbidity and mortality of patients undergoing RH, the second aim was to assess changes in both patients characteristic and surgical parameters and mortality rates in a single center institution.From 2001 to December 2015, 225 RH were performed in our center. We analyzed two time period: 2001-2007 and 2008-2015.Ninety days post operative mortality was observed in 9 cases (4%) for the overall cohort. We observed a difference between the two groups in the use of Pringle Maneuver (p0,001). This result is consistent in each major surgical indication: HCC (p=0,001), CLM (p=0,015) and BT (p=0,015). The estimated blood losses improved (p=0,028), particularly for the HCC cases (p=0,024). No difference was observed in terms of number of transfusions received between the two groups. Reduced length of stay was observed in the second group (p0,001), more markedly for CLM cases (p=0,001).To further improve the outcomes of RH, it is important to performed this major hepatectomy in hepatobiliary centers with an overall liver resection experience of at least few hundred cases.

The aim of this study was to critically analyze the early and long-term results of a newborn liver transplantation (LTx) centre using piggyback technique (PT) without venovenous bypass and portocaval shunt in the era of extended criteria donors (ECDs). Between 2002 and 2010, a total of 229 LTx were performed in 225 patients, with the shortest as possible cold ischemia time (CIT) policy. The charts of the donors and recipients and the intraoperative data were retrospectively reviewed in order to define the feasibility of PT and surgical outcome, and long-term graft and patient survival. PT feasibility rate was 100%, with a median duration of surgery of 390 min (range 210–630) and median unit of packed RBC transfused intraoperatively of 1 U (range 1–10). Median CIT was 400 min (range 130–870), and median AST peak was 403 mmol/L (range 48–16,900). ECDs graft rate was 85%. Over all primary dysfunction and non-function (PNF) rates were 7.4 and 2.2%, respectively and increased with graft steatosis >30% (P < 0.004). Mortality, morbidity, re-operation and re-LTx rates were 4.4, 25, 6.1 and 1.3%, respectively, and median hospital stay was 18 days (range 8–150). On the long term, graft and patient 5-year overall survival were 72 and 74%, respectively, and re-LTx rate was 0.4%. Survival was significantly affected by recipient HCV-Ab seropositive status (67 vs. 85%, P = 0.023). Liver transplantation can be performed with low morbidity and mortality rates, despite ECDs. PT is a safe and effective procedure that, combined with short CIT, entailed prompt early functional recovery of the grafts and positive long-term results.

Vascular endothelial growth factor (VEGF₁₆₅) is stored, transported and released by platelets. Platelet functional abnormalities have been described in patients with hepatocellular carcinoma (HCC). Thus, this study was designed to investigate the behavior of VEGF₁₆₅ with respect to platelet activation in HCC.Plasma and serum VEGF₁₆₅ and plasma sP-selectin levels were analyzed in patients with HCC (n=70) or cirrhosis (n=45) and control subjects (n=70). Given the thrombocytopenia that characterizes both HCC and cirrhotic patients, plasma VEGF₁₆₅ and sP-selectin as well as serum VEGF (plt-VEGF₁₆₅-load) levels were normalized by platelet counts.Median concentrations of plasma VEGF₁₆₅/platelet (p=0.002) and sP-selectin/platelet (p0.0001) were higher in HCC or cirrhotic patients compared to controls. Moreover, sP-selectin/platelet was the only independent variable predictive of plasma VEGF₁₆₅/platelet at multivariate analysis (p0.0001). Conversely, plt-VEGF₁₆₅-load correlated with tumor diameter (p0.05) but not with sP-selectin/platelet and was an independent predictor for 5year overall survival (p=0.012).The results obtained are suggestive for VEGF₁₆₅ release by tumor in HCC. It is plt-VEGF₁₆₅-load, but not plasma VEGF₁₆₅ or serum VEGF₁₆₅ that is an independent predictor for overall survival of HCC patients.

This study aimed to evaluate the early results of colorectal laparoscopic surgery with special attention to surgical and medical complications. The risk factors of such surgery are also investigated on the basis of a large series of operated cases: the preoperative knowledge of such factors could guide the operative program and the postoperative treatment with reduction of complications and improvement of the outcome. Between 1998 and 2008, 492 patients had been submitted to colorectal laparoscopic surgery by the same team: 387 for cancer and 105 for benign disease. All colorectal surgical operations are included in the series. No selection of the patients was made: laparoscopy was performed in all cases accepting the procedure. Several risk factors have been analysed in cases of fistula (age, pathology sex, type of the operation, cancer stages, preoperative radiochemotherapy, stool diversion and team experience) and in cases of medical complications (age, pathology, cancer stages and type of operation). The overall results in this series of laparoscopic colorectal operated cases are similar to other results published at present by the main surgical Department all over the world; no mortality and low number of medical (2.4%) and surgical complications (9.3%), with no differences also with the best open surgery series. Complete or partial conversion to open surgery was required in few cases (1.2%) and same others (1.4%) were operated again for bleeding or sudden anastomotic leakage. Regarding the risk factors in such surgery, a good correlation has been discovered between anastomotic leakage and the team experience, the age over 70 of the patients, the rectal tumour site in man, the advanced tumour stages, the previous radiochemotherapy, while medical complications seem to depend on advanced patients age and advanced cancer stages. Laparoscopic colorectal surgery at present is going to be considered the gold standard in the large majority of colorectal diseases including all cancer stages in the preoperative balance and in the early postoperative follow-up a special attention is required to same risk factors like the advanced patients age, the extended cancers, the low positioned rectal tumours. Complications are more frequent at the beginning of the experience of the surgical team and if more than one risk factors coexist, but it do not represent contraindication to laparoscopic surgery.

Aim The present study focused on nine patients with hepatocellular carcinoma (HCC) associated with Child A liver cirrhosis undergoing first-line liver resection and salvage liver transplantation (SLT) for liver tumor recurrence. Patients and methods Forty-six patients with HCC underwent liver transplantation (OLT); 37 (80.5%) were primary liver transplantations (PLTs) and 9 (19.5%) were SLTs. All patients who underwent SLT received minor transabdominal liver resections. Results The posttransplant 1-, 3-, and 5-year overall survival rates for SLT (88.9%, 88.9%, and 88.9%) were similar to those for PLT (78%, 62.7%, and 62.7%). Four (10.8%) patients in the PLT group had HCC recurrence, while there was zero recurrence in the SLT group. The 1-, 3-, 5-year disease-free survival rates for PLT (89%, 74%, and 74%) were similar to those for SLT (100%, 100%, and 100%). The 1-, 3-, 5-year disease-free survival rates after PLT were 89%, 74%, and 74%, and after SLT were 100%, 100%, and 100%, respectively. The operative mortality, intraperioperative bleeding, operative time, intensive care unit stay, in-hospital stay, and overall incidence of postoperative complications were similar in the two groups. Conclusions In our experience, SLT for HCC is a feasible procedure with similar results in terms of overall survival, disease-free survival, and postoperative complications to those reported for patients who underwent PLT at our institute. An important role exists for SLT as shown by the fact that such a strategy has been used in the 20% of the patients undergoing OLT for HCC.

Background The use of cadaveric vein allografts was first described by our group as a feasible option for venous reconstruction. The aim of this study was to report long-term results of this innovative technique. Methods Cold-stored veins harvested from donor cadavers were used as homologous grafts for venous reconstruction after vascular resection during pancreaticoduodenectomy. Surgical technique included patch closure or segmental interposition. Graft patency was assessed by computed tomography postoperatively and during follow-up. Postoperative morbidity and mortality were also analyzed. Results Eleven patients underwent venous resection and reconstruction by using fresh vein allografts for patch closure in four cases, conduit interposition in six cases and a Y-shaped graft interposition in one case. Median clamping time, operative time and estimated blood loss were 30 min, 6.6 h, and 337 ml, respectively. One patient, who had preoperative SMV thrombus, developed early portal vein thrombosis and died. Among the remaining 10 patients, there were no cases of graft thrombosis or stenosis during active follow-up (median 9, range 1–23, months). Conclusions Our experience with cold-stored vein allografts suggests that this technique is a useful option for treating major vascular resections during pancreaticoduodenectomy with good results on follow-up.

Objectives First bite syndrome (FBS) is an early postoperative pain syndrome characterized by the sudden onset of pain in the parotid region at the first bite of each meal. The etiology is not certain, hence a standardized therapy does not exist. Methods A 50-year old woman referred to us complaining of a swelling in the right parotid region. Fine-needle aspiration biopsy (FNAB) was diagnostic for pleomorphus adenoma of the deep lobe of the parotid gland. A 50-year old man presented with a mass in the right side of the neck, FNAB was diagnostic for parapharyngeal space neurinoma. The first patient was submitted to total parotidectomy with facial nerve preservation, the second to extracapsular dissection of the tumor. A week after surgery both patients developed FBS. A qualitative/quantitative description of pain was obtained by means of a self-coded questionnaire. The score ranges from 8 to 44, corresponding to the lowest and the highest discomfort possible, respectively. Acupuncture was used to treat these 2 patients. The treatment protocol comprised 6 sessions, one per week, lasting 30 minutes each. Results Our questionnaire was administered before and after treatment and the score dropped from 33 to 25 in the female, from 30 to 15 in the male patient. Conclusion FBS is a complication of upper cervical surgery with a high morbidity rate. We describe the first two cases of FBS that were successfully treated with acupuncture in our ENT department. We believe that this procedure may represent a valid therapeutic alternative in the future.

Colorectal tumor represents in Europe the second most common cause of cancer death. Surgical resection in case of colorectal liver metastasis remain for patients the only cure. In 2003, Jaeck et al. described a one or two-stage hepatectomy combined with PVE for initially non-resectable colorectal liver metastases. The aim of our study was to retrospectively review all patients who underwent to a two-stage hepatectomy for CLM and evaluate the safety and feasibility of the procedure. We review all patient who underwent two-stage hepatectomy for CLM in our center. From 2004 to March 2014, 57 patients were candidate for a two-stage hepatectomy for CLM. Thirty-two patients (55.9 %) were men and twenty-five women (44.1 %). Median age was 60.9 years old. In forty-six cases, the two-stage hepatectomy was completed. Of these 46 patients, 38 patients completed the procedure with a PVL and 8 underwent a secondary PVE. Seven patients were planned but did not performed PVL after intraoperative evaluation and neither PVE after secondary evaluation due to disease progression. Five cases were treated with a laparoscopic approach for the first step procedure. We had no death in this series. Ten patients developed complications after the first-stage operation and 18 patients had complications after the second stage. The median interval between the two stages was 66 days. Long-term overall survival was 52 months from the first liver surgery. This study demonstrated the feasibility of two-stage hepatectomy without postoperative mortality. In our last experience in selected patient, a laparoscopic first step should be performed. Patients selection is extremely important to propose the best therapeutic option for each one.

Minimally invasive liver surgery is performed with increasing frequency by hepatic surgeons. Laparoscopy was the first approach to be used and it is currently safely feasible in selected patients by experienced surgeons. Minor and major laparoscopic hepatectomies are now performed as a routine procedure in tertiary referral centers, with increasing evidence of long-term results comparable to traditional surgery together with the advantages of a minimally invasive approach. Robotic surgery, first developed for military purposes, showed to overcome some of the limits of laparoscopy, with an improved visual magnification, a 3-dimensional view and enhanced dexterity with better movement control. This allows an easier approach for resections in the posterior segments and for lesions close to major vessels. We present our preliminary experience of 20 consecutive robotic liver resection. Indications were colo-rectal liver metastasis (n = 7), hepatocellular carcinoma (n = 6), liver hemangioma (n = 2), biliary cystoadenoma (n = 2), breast cancer liver metastasis (n = 1), lung cancer liver metastasis (n = 1), symptomatic left liver lithiasis (n = 1). No conversion to laparotomy have been made and no hepatic pedicle clamping has been performed. The median duration of surgery was 141 min. There was no mortality, global morbidity was 10%. Median tumor size was 36 mm. Median post-operative length of stay was 5.7 days. Robotic surgery can be safely performed by experienced hepatic surgeons, resections of lesions in the posterior segments and close to the major vessels seem to be the best indication. Further studies are needed to clarify the exact role of robotics in liver surgery.

Preoperative diagnosis of hilar carcinoma (Klatskin tumor) is usually done according to the only clinical and imaging findings. However, in 5-15% of patients operated with this diagnosis, hilar stenosis is an inflammatory pseudo-tumoral benign one. We reported the case of a patient who underwent resection of common bile duct for suspicion of hilar carcinoma in whom, despite clinical and imaging findings highly suggestive of malignancy, pathologic examination revealed aspecific cholangitis. After a review of the literature, we conclude that resection of common bile duct is mandatory to exclude malignancy and allows excellent biliary drainage. Associated major hepatectomy should ideally be indicated, due to its higher risks, after pathological confirmation of cholangiocarcinoma, if necessary by frozen section.

We describe the case of a 72-year-old woman presenting with a 1-year history of recurrent epistaxis and unilateral progressive nasal obstruction with associated rhinolalia resulting from the presence of a tumor mass occupying two-thirds of the right nasal cavity. Histopathologically, neoplastic cells or "chief cells" were arranged in well-defined nests, which had the classic alveolar or so-called "zellballen" pattern. Immunohistochemical studies highlighted the presence of S-100 protein-positive sustentacular cells located at the periphery of the clusters of chief cells. The chief cells showed a diffuse and intense positivity for neuron-specific enolase and synaptophysin. A diagnosis of paraganglioma was made. The lesion was excised completely and the patient did not develop recurrences or distant metastases after 8 months of follow-up. Paragangliomas arising in the nasal cavity and paranasal sinuses are extremely rare tumors. We report on the clinical, histopathological and immunohistochemical findings of our case and review the cases previously described in the literature.

Background: Management of hepatocellular carcinoma (HCC) larger than 5 cm is still debated. The aim of our study was to compare morbidity and mortality after the surgical resection of HCC according to the nodule size. Methods: Since 2001, 429 liver resections for HCC were performed in our institution. We divided the cohort into two groups, 88 patients in group 1 patients with HCC diameter from 5 to 10 cm and 39 patients in group 2 with HCC diameter ≥10 cm. Results: In 30.7% of cases in the first group and in 35.9% of cases in the second group the HCC grew into a healthy liver. A major liver resection was performed in 36.3% of cases in group 1 vs . 66.6% in group 2 (P=0.001). In two cases for the first group and in ten cases in the second group a laparoscopic approach was performed. Median operative time was higher in group 2 (P=0.001). The median post-operative hospital stay was similar in the two groups (P=0.897). The post-operative morbidity was not different between the two groups (P=0.595). Conclusions: The tumour size does not contraindicate a surgical resection of HCC even in patient with HCC ≥10 cm.

Liver transplantation is the treatment of choice for patients with acute and chronic end-stage liver disease, when no other medical treatment is possible. Despite high rates of 1- to 5-year survival, long-term adverse effects of immunosuppressant agents remain of major concern. Current research and clinical efforts are made to develop immunosuppressant agents that minimize adverse effects along with a low rate of graft rejection. Tailoring immunosuppressive therapy to individual patients by the use of proliferation signal inhibitors seems to be the best way to minimize toxicity and increase efficacy. Recently everolimus has been introduced in clinical practice; among its adverse effects an increased incidence of arterial graft thrombosis in renal transplants, vascular anastomosis leakage, impaired wound healing, and thrombotic microangiopathy have been reported. We present the case of a 54-year-old patient submitted to liver transplantation for end-stage liver disease treated by an extra-anatomic aortoiliac-hepatic arterial graft anastomosis and early postoperative introduction of everolimus for acute renal failure. Postoperative period was characterized by two abdominal collections and reactivation of cytomegalovirus infection that were treated by percutaneous drainage and antiviral therapy, respectively; the patient is well after 8-month followup with patency of the arterial conduit and no leakage.

Objectives:To assess the clinical utility of elective neck dissection in node-negative recurrent laryngeal carcinoma after curative radiotherapy for initial early glottic cancer.Methods:A retrospective review was undertaken of 110 consecutive early glottic cancer patients who developed laryngeal recurrence after radiotherapy (34 recurrent T1, 36 recurrent T2, 29 recurrent T3 and 11 recurrent T4a) and received salvage laryngeal surgery between 1995 and 2005.Results:Six patients presented with laryngeal and neck recurrence and underwent salvage laryngectomy with therapeutic neck dissection, 97 patients with recurrent node-negative tumours underwent salvage laryngeal surgery without neck dissection and only 7 underwent elective neck dissection. No occult positive lymph nodes were documented in neck dissection specimens. During follow up, only three patients with neck failure were recorded, all in the group without neck dissection. There was no significant association between the irradiation field (larynx plus neck vs larynx) and the development of regional failure. A higher rate of post-operative pharyngocutaneous fistula development occurred in the neck dissection group than in the group without neck dissection (57.2 per cent vs 13.4 per cent, p = 0.01). Multivariate logistic regression analysis showed that early (recurrent tumour-positive, node-positive) or delayed (recurrent tumour-positive, node-negative) neck relapse was not significantly related to the stage of the initial tumour or the recurrent tumour. An age of less than 60 years was significantly associated with early neck failure (recurrent tumour-positive, node-positive).Conclusion:Owing to the low occult neck disease rate and high post-operative fistula rate, elective neck dissection is not recommended for recurrent node-negative laryngeal tumours after radiation therapy if the initial tumour was an early glottic cancer.

Introducción: Las zoonosis son infecciones de transmisión del animal al hombre, ya sea directamente (a través del contacto directo o contacto con productos de origen animal) o indirectamente (a través de un vector intermedio, tal como un artrópodo). Los agentes causales incluyen bacterias, parásitos, virus y hongos. El propósito de esta revisión es hacer un examen preciso de todas las enfermedades zoonóticas que pueden ser responsables de oído, nariz y garganta (ENT) participación. Metodología: Se realizó una búsqueda en PubMed combinando los términos (otorrinolaringología o Rinología o laringología o otología or mastoiditis u otitis o sinusitis o laringitis o rinitis o faringitis o de la epiglotitis o disfonía o la oreja o la laringe o la nariz or faringe) con cada uno de los agentes etiológicos de las zoonosis para el período entre enero de 1997 y agosto de 2012 sin restricciones de lenguaje. Resultados: Se seleccionaron un total de 164 artículos y se examina. Laringe es el órgano más frecuentemente afectado ENT, seguido de la cavidad oral, faringe, y el cuello. Las bacterias fueron los microorganismos más representativos implicados. La nariz y las glándulas salivales mayores fueron los más afectados frecuentemente por protozoos; senos paranasales, cavidad oral, el oído, el cuello, los nervios y las vías respiratorias superiores por las bacterias, y laringe por hongos. Conclusiones: La clínica de otorrinolaringología y signos pueden estar presentes en muchas de las enfermedades zoonóticas, algunos de los cuales también están presentes en los países industrializados. La mayoría de las enfermedades zoonóticas no son comúnmente encontrados por los especialistas ENT. La apreciación de la posible aparición de estas enfermedades es importante para un enfoque microbiológico correcto , que a menudo requiere medios de cultivo especiales y técnicas de diagnóstico. Introduction: Zoonoses are infections transmitted from animal to man, either directly (through direct contact or contact with animal products) or indirectly (through an intermediate vector, such as an arthropod). The causative agents include bacteria, parasites, viruses, and fungi. The purpose of this review is to make an accurate examination of all zoonotic diseases that can be responsible of ear, nose, and throat (ENT) involvement. Methodology: A PubMed search was performed combining the terms (otorhinolaryngology OR rhinology OR laryngology OR otology OR mastoiditis OR otitis OR sinusitis OR laryngitis OR rhinitis OR pharyngitis OR epiglottitis OR dysphonia OR ear OR larynx OR nose OR pharynx) with each one of the etiological agents of zoonoses for the period between January 1997 and August 2012 without language restrictions. Results: A total of 164 articles were selected and examined. Larynx was the most commonly involved ENT organ, followed by oral cavity, pharynx, and neck. Bacteria were the most representative microorganisms involved. Nose and major salivary glands were affected most frequently by protozoa; paranasal sinus, oral cavity, ear, neck, nerves and upper airway by bacteria; and larynx by fungi. Conclusions: ENT symptoms and signs may be present in many zoonotic diseases, some of which are also present in industrialized countries. Most zoonotic diseases are not commonly encountered by ENT specialists. Appreciation of the possible occurrence of these diseases is important for a correct microbiological approach, which often requires special culture media and diagnostic techniques.

Primary cancer of the subglottic region is very rare and delay in diagnosis often leads to a poor prognosis. We retrospectively reviewed 49 patients with primary cancer of the subglottic larynx observed from 1969 to 1993 in the ORL Clinic of the University of Florence. This number constitutes 1.6% of all laryngeal cancers observed during this period. Four (8.2%) patients were stage T1, 13 (26.5%) T2, 27 (55.1%) T3, and 5 (10.2%) T4. Forty-one patients were eligible for assessing the disease-free five-year survival rate, 17 of whom were treated with surgery alone, 6 with radiotherapy alone and 18 with combination therapy (surgery for the primary tumor and postoperative radiotherapy for cervical nodes). The five-year survival rate for the three treatment types was 47%, 0% and 83.3%, respectively. The overall survival rate was 56.1%. Combination therapy produced a significantly higher (P = 0.001) disease-free survival than surgery alone or radiotherapy alone.

Laparoscopic surgery for gastric cancer (GC) was introduced in the past decade because it was considered less invasive than open surgery, resulting in less postoperative pain, faster recovery, and improved quality of life. Several studies have demonstrated the safety and feasibility of this procedure. We analyzed our preliminary experience with this procedure. From November 2003 to December 2004, 20 patients affected by gastric adenocarcinoma were operated on with a totally laparoscopic or laparoscopic-assisted approach. This series included 10 women and 10 men, aged from 34 to 75 years. Procedures consisted of eight total gastrectomies, three subtotal Billroth I and seven Billroth II gastrectomies, one proximal gastrectomy, and one wedge resection. According to the TNM classification, we observed five patients at stage Ia, four at stage Ib, three at stage II, one at stage IIIa, two at stage IIIb, and five at stage IV. In all patients the procedures were completed without any conversion. Operative time ranged from 150 to 300 min. The number of dissected lymph nodes ranged from 23 to 47. No mortality was observed. Overall morbidity rate was 10% (two cases), with one enteric fistula and one esophagojejunal anastomotic leakage associated with pancreatitis. Excluding these two patients, postoperative stay was between 12 and 20 days. Even though accompanied by a difficult learning curve, safety and feasibility are widely demonstrated, but a skilled and experienced surgeon is required. Accurate selection of patients is mandatory and curative resection is achievable in cases where GC is not advanced.

Although a steady decline in the incidence and mortality rates of gastric carcinoma has been observed in the last century worldwide, the absolute number of new cases/year is increasing because of the aging of the population. So far, surgical resection with curative intent has been the only treatment providing hope for cure; therefore, gastric cancer surgery has become a specialized field in digestive surgery. Gastrectomy with lymph node (LN) dissection for cancer patients remains a challenging procedure which requires skilled, well-trained surgeons who are very familiar with the fast-evolving oncological principles of gastric cancer surgery. As a matter of fact, the extent of gastric resection and LN dissection depends on the size of the disease and gastric cancer surgery has become a patient and “disease-tailored” surgery, ranging from endoscopic resection to laparoscopic assisted gastrectomy and conventional extended multivisceral resections. LN metastases are the most important prognostic factor in patients that undergo curative resection. LN dissection remains the most challenging part of the operation due to the location of LN stations around major retroperitoneal vessels and adjacent organs, which are not routinely included in the resected specimen and need to be preserved in order to avoid dangerous intra- and postoperative complications. Hence, the surgeon is the most important non-TMN prognostic factor in gastric cancer. Subtotal gastrectomy is the treatment of choice for middle and distal-third gastric cancer as it provides similar survival rates and better functional outcome compared to total gastrectomy, especially in early-stage disease with favorable prognosis. Nonetheless, the resection range for middle-third gastric cancer cases and the extent of LN dissection at early stages remains controversial. Due to the necessity of a more extended procedure at advanced stages and the trend for more conservative treatments in early gastric cancer, the indication for conventional subtotal gastrectomy depends on multiple variables. This review aims to clarify and define the actual landmarks of this procedure and the role it plays compared to the whole range of new and old treatment methods.

Hepatocellular carcinoma (HCC) tends to have a particular invasiveness toward the portal vein (PV) branches and hepatic veins. This situation can hamper major surgical resection with a risk of postoperative liver failure due to the small future liver remnant (FLR) in cirrhotic livers. These patients are then usually directed to palliative treatments with poor results. The associating liver partition and PV ligation (PVL) in staged hepatectomy (ALPPS) strategy is one of the main surgical innovations in recent years in the field of liver surgical oncology. The ALPPS approach could allow surgical resection in patients with HCC and associated major vascular invasion. Among 1,143 liver resection performed in our center, the ALPPS approach was employed in order to induce rapid hypertrophy of the left FLR in patients with HCC and associated major vascular invasion. This strategy consists of combining the in situ splitting of the liver along the main portal scissura or on the right side of the falciform ligament and PVL in a strategy of staged hepatectomy. In our experience the ALPPS approach allowed us to achieve a sufficient FLR in two cases of HCC with major vascular invasion, in which the classic two-stage strategy could not be applied. In both cases the patients could undergo major hepatectomies without mortality. This novel strategy could expand the number of patients undergoing major liver resections that were previously considered non-resectable because of the risk of liver decompensation for an insufficient FLR.

Objective The objective of this study was to quantify incidence rates (IR) and risks of de novo tumors (except nonmelanoma skin cancers) in patients who underwent orthotopic liver transplantation (OLT) in central and southern Italy. Methods Data were collected on 1675 patients (75.5% males) who underwent OLT in six Italian transplantation centers in central and southern Italy (1990–2008). The time at risk of cancer (person years [PY]) was computed from OLT to the date of cancer diagnosis, death, or last follow-up, whichever occurred first. The number of observed cancer cases were compared with the expected one using data from population-based cancer registries. We computed gender- and age-standardized incidence ratios (SIRs) and 95% confidence intervals (CIs). Results During 10,104.3 PYs (median follow-up, 5.2 years), 98 patients (5.9% of the total) were diagnosed with a de novo malignancy (for a total of 100 diagnoses). Twenty-two of these cancers were post-transplantation lymphoproliferative disorders (PTLD; 18 non-Hodgkin lymphoma [NHL] and 2 Hodgkin's lymphoma [HL]), 6 were Kaposi's sarcoma (KS), and 72 were solid tumors (19 head and neck [H&N], 13 lung, 11 colon-rectum, 6 bladder, and 4 melanoma). The overall incidence was 9.9 cases/103 PYs, with a 1.4-fold significantly increased SIR (95% CI, l.2–1.7). Significantly increased SIRs were observed for KS (37.3), PTLD (3.9), larynx (5.7), melanoma (3.1), tongue (7.1), and H&N (4.5) cancers. Conclusions These results confirmed that OLT patients are at greater risk for cancer, mainly malignancies either virus-associated or related to pre-existent factors (eg, alcohols). These observations point to the need to improve cancer surveillance after OLT. The on-going enrollment of patients in the present cohort study will help to elucidate the burden of cancer after OLT and better identify risk factors associated with its development.

Introduction An inguinal hernia is a common surgical disease in elderly patients, but an association with intra-abdominal malignancies is rare. Case presentation We report a case of a 78-year-old Caucasian woman presenting with a right inguinal mass suspected to be an irreducible hernia. A computed tomography scan showed the presence of the cecum in her inguinal canal, with an irregular thickening of the cecal wall suggesting a neoplasm within the inguinal hernia. A colonoscopy was not completed owing to the huge involvement of the cecum into the hernia sac. A laparotomy was performed, at which time the cecum was herniated through her right inguinal canal and the cecal tumor had infiltrated her abdominal wall and femoral artery. A right inguinal incision was necessary for good vascular control and to carry out an en bloc resection of the tumor with the inguinal wall. A right colectomy was performed and the inguinal wall repaired. The postoperative course was uneventful and our patient received adjuvant radiochemotherapy. Conclusion We describe a rare case of a locally advanced cecal tumor presenting as a right inguinal hernia. Both diagnosis and surgical treatment in elderly patients represent a challenge for the surgeon in cases of aggressive tumors as reported in this paper.

Venous resections and reconstructions of portal vein and/or superior mesenteric vein in course of pancreaticoduodenectomy are becoming a common practice and many surgical options have been described, from simple tangential resection and venorrhaphy to large segmental resections followed by interposition grafting. The aim of this study was to report the first experience of using fresh cadaveric vein allografts for venous reconstruction during pancreaticoduodenectomy focusing on technical feasibility and postoperative outcomes. From January 2001 to October 2012, out of 151 patients undergoing pancreaticoduodenectomy for pancreatic head tumor, 22 (14.5 %) received a vascular resection of the mesentericoportal axis. In five of these patients, vascular reconstruction was accomplished by using cold-stored venous allografts of iliac and femoral veins from donor cadaver. Patients’ data, surgical techniques, and clinical outcomes were analyzed. Five patients undergoing pancreaticoduodenectomy were selected to receive a vascular reconstruction using a fresh venous allograft for patch closure in three cases, conduit interposition in one case and a Y-shaped graft in the last case. No graft thrombosis or stenosis occurred postoperatively and at long-term follow-up. Mortality rate was zero. The use of fresh vein allografts is a feasible and effective technique for venous reconstruction during pancreaticoduodenectomy. However, prospective surveys including large cohorts of patients are necessary to confirm these results.

Factors that contribute to malignant transformation of laryngeal pre-neoplastic lesions remain largely unknown. Potential etiological factors may be related to a genetically controlled sensitivity to environmental carcinogens. In this study, we investigated bleomycin-induced chromosome damage in 15 patients who experienced a malignant transformation of preneoplastic laryngeal lesions during follow-up, as compared with chromosome fragility in 30 historical controls with no progression of keratoses during a 10-year follow-up, in a match-paired analysis. Chromosomal analysis demonstrated higher sensitivity to clastogens in patients with malignant progression of laryngeal pre-neoplastic lesions than that of control patients with no evolution of their original laryngeal keratoses (p = 0.003). Furthermore, among the study patients, chromosome sensitivity was most apparent in non-tobacco users with malignant transformation of laryngeal disease. Our data suggest that subjects with pre-neoplastic laryngeal lesion showing increased susceptibility to carcinogens could be at higher risk for development of laryngeal carcinoma. © 1996 Wiley-Liss, Inc.

Background: A potential mechanism of the infection would be an infected donor, contamination at the time of the infusion and/or packaging, back-table procedure, and finally during the transplantation, all are potential sources of infection. The aim of our study is to analyze the incidence and significance of infection in the preservation solution according with the graft temperature. The second aim was to analyze the impact graft temperature on the clinical infections and the ischemia reperfusion injury. Methods: Sixteen donors were prospectively included in this study, including 9 males and 7 females. The liver graft temperature monitoring shows variation in four different phases: at the harvesting beginning, before the graft packaging, at the beginning of the backtable, at the end of the backtable. Results: There was no correlation between the functionality of the graft and the temperature of the perfusion fluid. Conclusions: In conclusion, we did not found a correlation between graft temperature, culture of the preservation solution and early post-transplant follow up.

Introduction Hydatid disease is a helminthic anthropozoonosis with worldwide distribution due to the close associations among sheep, dogs, and humans. It can occur almost anywhere in the body with a variety of imaging features, which may change according to the growth stage, associated complications, and affected tissues. A definitive diagnosis requires a combination of imaging, serologic and immunologic studies. Ultrasonography, computed tomography and magnetic resonance imaging are highly accurate in detecting a hepatic hydatid cyst. However, hepatic hydatid cysts in an unusual location and/or of an unusual dimension, with atypical imaging findings, may complicate the differential diagnosis. Surgical treatment remains the best treatment. Case presentation We describe an unusual case of a giant hydatid cyst, with exophytic growth from the right lobe of the liver of a 55-year-old Egyptian man. The cyst was strongly adhered to his ipsilateral kidney, which was displaced in a downwards and anterior direction, close to his abdominal wall, simulating a retroperitoneal origin. This atypical growth raised doubts about the most appropriate surgical approach. Magnetic resonance imaging easily clarified the origin of the cyst as our patient’s liver, allowing accurate surgical planning. Conclusion Rarely, hydatid cysts can reach an extremely large size without any additional symptoms. Giant cysts need radical therapy because they might lead to perforation and anaphylaxis in some patients. Magnetic resonance imaging is very useful in the study of hydatid disease because of its capacity to allow a large field of view, multiplanar acquisition, and high contrast resolution. In some unusual hepatic presentations, magnetic resonance imaging can be used to determine the correct anatomical relationships.

Yttrium-90 microspheres radioembolization has shown to be an effective modality of treatment in patients with primary or metastatic liver tumours [1-4]. It is usually offered to patients with advanced liver cancers. However, surgical experience after radioembolization is very limited to anecdotal cases mainly related to hepatocellular carcinoma. We have treated patients with hepatocellular carcinoma or liver metastasis mainly from colon, breast, melanoma and neuroendocrine tumours. In our experience after such treatment we were able to downstage the tumour to surgery only in the case of hepatocellular carcinoma. Five patients had liver transplantation and 1 had right hepatic resection after Yttrium-90 microspheres radioembolization. Of note 2 patients had neoplastic infiltration of a portal vein branch which resolved after treatment with Yttrium-90 microspheres radioembolization. The extra-hepatic spread was ruled out and later they were both transplanted. Here we report our initial single center experience with Yttrium-90 microspheres radioembolization as downstaging and bridging method for hepatocellular carcinoma prior liver surgery, resection or liver transplantation.

Background Survivin, also known as BIRC5, is the smallest member of the mammalian IAP family and is a well recognized inhibitor of apoptosis with an important role in cell-cycle regulation. It is detected in fetal and neoplastic adult tissue, but not in normal tissues. Survivin acts on cancer promotion not only by the inhibition of apoptosis but also by acceleration of the proliferative activity of cancer cells and several papers have suggested the involvement of this protein in hepatocarcino-genesis. It has been reported that the detection of HCC biomarkers circulating as IgM immune complexes (ICs) improved the diagnosis and prognosis of HCC. The aim of this study was to compare the expression of survivin as an IgM immune complex in serum from healthy controls and of patients with cirrhosis and patients with HCC to identify a novel biomarker for the monitoring of liver diseases. Methods Serum levels of survivin-IgM from 1 97 individuals, including 39 healthy subjects, 94 patients with cirrhosis and 64 with HCC, were measured by ELISA and the relationship with clinical parameters was evaluated. Results Survivin-IgM was almost undetectable in sera from healthy subjects, high in patients with cirrhosis, and moderately lower in patients with HCC. The survivin-IgM assay was positive in 62 of 94 patients with cirrhosis (66%) and in 28 of 64 patients with HCC (43.7%) using a cut-off of 264.89 AU/mL (specificity of 94%). Statistical analysis showed that IC values were significantly different between groups (cirrhosis versus healthy control group, pConclusions The high expression of survivin-IgM in sera from patients with cirrhosis and the values of sensitivity indicate that survivin-IgM could be a novel candidate biomarker for cirrhotic disease. Furthermore, the increase in ICs with the progression of Child score seems to promote the survivin-IgM immune complex as marker of liver failure. Survivin-IgM was found to be lower in sera from HCC patients. Follow-up studies are in progress to monitor patients with cirrhosis and to validate the association of the downregulation of this marker with progression towards hepatocellular carcinoma.

Total pancreatectomy (TP) consists in removing the entire pancreas, together with part of stomach, duodenum, common bile duct, gallbladder, spleen, and nearby lymph nodes.

Background. Selective neck dissection as a part of an elective or therapeutic treatment of the neck is a common practice during the surgical treatment of patients with head and neck cancer. Recently, the need for routine dissection of level IIb has been discussed. The aim of this study was to verify the incidence of metastases at level IIb in patients with clinically negative necks (N0) and clinically positive necks (N1) and dis- cuss the need for its excision. Methods. A total of 114 patients with head and neck cancer undergoing neck dissection were prospectively analyzed. The total number of neck dissections analyzed was 148. The surgical specimens from each node level of the neck were pathologically diagnosed, with special attention to level IIb. Univariate associa- tions between N classification and IIb positive cases were assessed using logistic regression and between IIa and IIb posi- tive cases using Fisher exact test. Results. Of 148 neck dissections performed, level IIb resulted positive in 5 cases (3.3%): 1 patient with laryngeal can- cer, 1 patient with oral cavity cancer, and 2 patients with oropha- ryngeal cancer, of which 1 underwent bilateral neck dissection. According to clinical N classification, for N0 and N1 the inci- dence of positive level IIb was 2% and 5%, respectively. All the cases with metastases at level IIb also showed metastases at level IIa. A statistically significant association between the pres- ence of nodal metastases at level IIb and those at level IIa (p

The goal of this study was to identify host and tumour factors associated with postoperative pneumonia (PP) in a selected population of laryngeal cancer patients, treated by partial laryngectomy in 20 years at our Institution and to assess its potential prognostic impact. Clinical records of 416 consecutive patients were retrospectively reviewed. Tobacco consumption, body mass index (BMI), previous pulmonary disease, age, sex, preoperative blood gas analysis values, tumour stage and type of surgery were tested as potential risk factors for PP. Finally, the prognostic impact of these variables, including PP, in terms of disease-free and actuarial survival by Kaplan-Meier and Cox analyses were evaluated. PP developed in 73 patients (16.8%). We identified two groups of patients: 26 patients experienced an early PP within the first 7-9 days after surgery, whilst 44 experienced an ab ingestis PP following attempts of oral food intake restoration, three patients died for PP related sepsis. At multivariate Cox analysis, age older than 60 years and BMI greater than 30 were statistically associated with early PP; whereas male gender and laryngectomy with neck dissection were statistically related to a higher risk of ab ingestis PP. Interestingly, the occurrence of early PP was a negative independent prognostic factor for 5-years disease-free and actuarial survival (p=0.049 and p=0.001, respectively). The occurrence of early-onset pneumonia in laryngeal cancer patients selected for conservative laryngectomies is predictable and associated with poor clinical outcome.

Myxoid liposarcoma (ML) has a high predilection for extrapulmonary sites of metastases, including intra-abdominal metastases, but pancreatic involvement is extremely rare. Here, we report the case of a 66-year-old male patient, who underwent pancreaticoduodenectomy for isolated pancreatic metastasis of ML of the left lower extremity that had been excised 6 years before. Completion pancreatectomy was necessitated afterwards for a delayed haemorrage associated with pancreatic fistula. Currently the patient is alive with no evidence of disease. Highly selected patients with isolated pancreatic metastasis of soft tissue sarcoma may benefit from a curative surgical resection.

To evaluate the role of surgical treatment for isolated loco-regional recurrences of operated gastric adenocarcinoma.Among the 837 patients operated for gastric adenocarcinoma between December 1979 and April 2004, 713 (85%) underwent resection with curative intent. A retrospective review of a prospectively collected gastric cancer database was carried out. Overall recurrence rate was 44% (315 cases), with 75% occurring within the first 2 years from the operation. Isolated L-R recurrences were observed in 38 (12%) patients. Symptomatic lesions were observed in 27 (71%).Six (16%) patients were macroscopically resected with curative intent. The recurrence was located in the gastric stump after a STG in three patients, in the esophagojejunal anastomosis after a TG in two patients and in the gastric bed after a TG in one patient. Surgical procedures consisted of three secondary TG, two esophagojejunal resection and one excision of an extraluminal recurrence. Postoperative complications occurred in two patients (33%), including one anastomotic leakage and one hemorrhage. The latter patient died of sepsis 35 d after the surgery (mortality rate 17%). All patients died of recurrent gastric cancer: 2 within 1 year from surgery (8 and 11 mo, respectively), 2 after 16 and 17 mo respectively and 1 after 28 mo from the second operation.Surgery plays a very limited role in the treatment for isolated loco-regional recurrence of gastric adenocarcinoma.

The aim of the present study was to analyze the risk features and to discuss the preventive measures and treatment of stomal recurrence (SR) after total laryngectomy (TL), and to investigate the clonal relationship between the primary and recurrent lesions. We reviewed a series of 25 patients affected by SR after TL for laryngeal squamous cell carcinoma. A subset of 7 coupled primary and recurrent carcinomas were examined for microsatellite alterations that were used as a marker of genetic lineage. The incidence of SR was higher in patients with initial subglottic lesions (subglottic, transglottic, or glottic-subglottic tumors) than in those with other locations of laryngeal cancer (p = .013). In addition, the frequency of SR was significantly higher in patients who underwent preoperative tracheotomy, performed 48 hours or more before the TL, than in the group of patients who did not receive preoperative tracheotomy (23.3% versus 0.46%, p < .001). According to microsatellite analysis, of the 5 informative patients, 2 demonstrated discordant alterations in the recurrent tumor indicative of clonal heterogeneity, 2 demonstrated identical alterations, and 1 showed an additional alteration in the recurrent tumor. Our analysis supports the hypothesis that a subset of SRs after TL may be second primary tumors, genetically unrelated to the primary laryngeal lesion.

Clinical otolaryngologists frequently encounter nasal foreign bodies (FBs) particularly among children. The removal of nasal FBs is a common otolaryngological practice. However, occasionally trauma results from FBs being lodged in the nasal cavity especially through the nasolacrimal duct. In this article we present an unusual case of a FB that from the left medial canthus went inside the nasolacrimal duct, then through the inferior turbinate and stuck in the floor of the nose. We describe the transnasal endoscopic approach used and we recommend that the treatment be done as soon as possible to avoid complications.
