Background. Type-2 inflammation commonly marks asthma in childhood. Also, gut and lung dysbiosis is detectable in patients with asthma. Strain-related probiotic supplementation may restore a physiological immune response, dampen airway inflammation, and repair dysbiosis. Therefore, the probiotics in pediatric asthma management (PROPAM) study is aimed at demonstrating that Ligilactobacillus salivarius LS01 (DSM 22775) and Bifidobacterium breve B632 (DSM 24706) mixture could reduce asthma exacerbations in children, followed in a primary care setting. Methods. The study was randomized, placebo-controlled, and double-blind. It involved 11 Italian primary care pediatricians. The probiotic mixture (containing Ligilactobacillus salivarius LS01 1 × 10 9 live cells and Bifidobacterium breve B632 1 × 10 9 live cells) or placebo was taken twice daily (1 sachet in the morning and 1 in the evening) for eight weeks and subsequently once daily for a further eight weeks. Outcomes included number, severity, and duration of asthma exacerbations, intensity of maintenance and as need treatments, and safety. Results. The per-protocol population included 422 children (mean age seven years, 240 males and 182 females). The probiotic mixture significantly reduced the number of asthmatic exacerbations ( OR = 3.17 ). In addition, the number of children with two exacerbations was less than a third in the active group ( OR = 3.65 ). Conclusions. This PROPAM study demonstrated that probiotic strains Ligilactobacillus salivarius LS01 (DSM 22775) and Bifidobacterium breve B632 (DSM 24706) were safe and significantly reduced by more than a third the frequency of asthma exacerbations. At present, the first-line treatment of asthma is still drug-based, but specific strains of probiotics may be auxiliary remedies.

Background: Several studies showed important differences in the interpretation of spirometry based on different reference values, in particular by comparing European Respiratory Society (ERS) 1993 and Global Lung Function Initiative (GLI) 2012. The validation of new reference values in local populations is essential before they can be used in an appropriate manner. This study aimed to investigate the fit of GLI reference values in a healthy Italian working population. Methods: Spirometry data were collected in 1355 workers during their health surveillance medical examination conducted for exposure to chemical and biological risk factors. A single portable spirometer that met the ATS/ERS recommendations for occupational testing was used and calibrated daily. Results: Average z-score were −0.13 (with a median of −0.17), −0.25 (with a median of −0.24), and 0.18 (with a median of 0.17) for FEV1, FVC, and FEV1/FVC ratio, respectively. Considering only the normal-weighted workers, the average z-scores were −0.07 (with a median of −0.16), −0.15 (with a median of −0.16), and 0.07 (with a median of 0.02) for FEV1, FVC, and FEV1/FVC ratio, respectively. Conclusions: GLI 2012 reference values fit the Italian data satisfactorily, resulting as more accurate than ERS 1993, especially in women, normal-weighted subjects, aged 30−50 years, and for height < 165 cm.

Chronic postsurgical pain (CPSP) can occur frequently after thoracic surgery.This retrospective study aimed to determine CPSP prevalence, risk factors, neuropathic pain (NP) occurrence, and its impact on quality of life.About 200 patients who underwent lung resection via minithoracotomy or thoracoscopy between January 2017 and December 2017 were assessed 4-12 months postoperatively via phone interview for chronic pain by a 0-10 Numeric Rating Scale, for NP using the Douleur Neuropathique 4 test, and for quality of life using a Short Form-36 (SF-36) Health Survey (Italian version).CPSP incidence was 35% (n = 70 of 200; 95% CI 41-28) of which 31.5% (n = 22 of 70; 95% CI 41-21) was with NP. Only 10% of patients with CPSP reported severe chronic pain. According to univariate analysis, CPSP was associated to moderate and severe acute postoperative pain (P 0.001), open surgery (P = 0.001), and female gender (P = 0.044). According to multivariable analysis, independent risk factors for CPSP development included moderate-to-severe acute postoperative pain occurrence (odds ratio 32.61; 95% CI 13.37-79.54; P 0.001) and open surgery (odds ratio 6.78; 95% CI, 2.18-21.03; P = 0.001). NP incidence was higher in female patients (16% in women and 6% in men, respectively; P = 0.040). A significant decrease in all SF-36 Health Survey domain scores was recorded for patients with CPSP and NP (P 0.001).More than one of three patients who underwent lung resection could develop CPSP, frequently showing neuropathic component. Female gender reported a higher CPSP and NP incidence. Moderate-to-severe acute postoperative pain occurrence and open surgery seem to be independent risk factors for CPSP. Chronic pain and NP have a negative impact on quality of life, decreasing the SF-36 scores of all domains.

Purpose To evaluate the possible role of occupational low dose ionizing radiation exposure in increasing the healthcare workers’ risk of thyroid functional alterations. Methods 120 healthcare workers exposed to ionizing radiation (60 belonging to category A with a potential exposure to an annual dose between 6 and 20 mSv and 60 to category B potentially exposed to an annual dose between 1 and 6 mSv) were compared with a control group consisting of 60 unexposed healthcare subjects assessing serum levels of different thyroid function parameters as free triiodothyronine, free thyroxine, thyroid stimulating hormone and thyroid autoantibodies. Age, gender, history of thyroid diseases, job task, dosimetric values were analysed as possible influencing factors using linear and multiple logistic regression analysis. Results Exposed workers showed significantly higher average levels of thyroid stimulating hormone, and lower average levels of free triiodothyronine and free thyroxine than non-exposed workers, although nonsignificant differences were observed between the two different exposure categories. According to the values of the thyroid hormones a condition of hypothyroidism has been considered in 11 exposed workers (9.2 %) and interestingly this clinical condition was significantly associated with ionizing radiation exposure. Conclusions Low dose ionizing radiation exposure would seem to significantly influence levels of free triiodothyronine, free thyroxine, thyroid stimulating hormone, then suggesting a possible increased risk of hypothyroidism in healthcare workers although no relationship could be determined with exposure category. However, further studies are necessary to confirm such association on greater number of workers in order also to define a possible dose-response relationship.

Background Clinical audit is a process by which physicians or other health care professionals perform a regular and systematic review of their clinical practice and amend it, when necessary. An internal audit allows to review the activities carried out by professionals, in order to assess the appropriateness, effectiveness, efficiency and safety of the services provided. Aim of this study was to apply the process of clinical audit to the obesity/overweight care in toddlers. After the correction of the nutritional errors that were considered potentially responsible for the excess weight gain, the effect of the changes of dietary advice on the frequency of overweight/obesity was assessed in a cohort of children aged 24–36 months. Methods Three Italian primary care pediatricians set up the audit strategy by recognizing the high prevalence of overweight and obesity in the entire cohort of toddlers born in 2005, 2006 and 2007 (Pre-Audit group, age 24–36 months old) under their care. By reviewing their clinical practice, they changed the protocol of weaning and feeding up to 36 months, mainly reducing protein and sugar excess. The change involved the cohorts of toddlers born in the years 2010, 2011 and 2012 (Post-Audit group). Results Change in the approach of pediatricians to children’s diet yielded a reduction of the frequency of overweight/obesity in children between 24 and 36 months of life from 26.3% in the Pre-Audit group to 13.9% in the Post-Audit group (p Conclusion Clinical audit revealed high rates of obesity/overweight among toddlers. The practice developed a new strategy for nutritional counseling, which was effective in reducing the frequency of overweight/obesity in young children.

Introduction: Spirometry is the main pulmonary function test routinely employed in the occupational medicine practice. Its interpretation depends on the choice of the theoretical reference values. Therefore, our objective was to retrospectively evaluate the differences in the spirometric interpretation according to the reference values used. Methods: A total of 2462 spirometries performed during health surveillance programs were analyzed. Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and FEV1/FVC ratio were compared according to three different reference values: the European Coal and Steel Community (ECSC) 1971, the European Respiratory Society (ERS) 1993, and the Global Lung Initiative (GLI) 2012. Results: The GLI 2012 provided significantly higher predicted mean FVC and FEV1 values compared to the ERS 1993 and significantly lower compared to the ECSC 1971. The GLI 2012 were able to detect all the obstructive deficits and mixed patterns diagnosed with ECSC 1971 and ERS 1993, in addition to others not diagnosed by these two latter reference values. The number of restrictive patterns identified through the GLI 2012 was significantly reduced and increased compared to those diagnosed using the ECSC 1971 and the ERS 1993, respectively. Discussion: In comparison to the GLI 2012, the ERS 1993 values significantly underestimated obstructive and restrictive alterations. Conversely, the ECSC 1971 significantly underestimated obstructive changes, while overestimated restrictive patterns, compared to GLI. Although the GLI reference values may provide a correct spirometric interpretation, their validation in an Italian worker population is necessary to confirm their possible use in routine occupational health programs.

The widespread industrial application of nanotechnology has increased the number of workers exposed to engineered nanomaterials (ENMs), but it is not clear to what extent prevention guidance is practiced. Our aim was to explore the extent that companies manufacturing and/or using ENMs apply risk assessment and management measures. Thirty-four companies were surveyed with an international 35-item questionnaire investigating company and workforce features, types of ENM handled, and risk evaluation and preventive measures adopted. Among participating companies, 62% had a maximum of 10 employees. Metal-based nanomaterials were most frequently identified (73%). Environmental monitoring was performed by 41% of the companies, while engineering exposure controls were approximately reported by 50%. Information and training programs were indicated by 85% of the sample, only 9% performed specific health surveillance for ENM workers. Personal protective equipment primarily included gloves (100%) and eye/face protection (94%). This small-scale assessment can contribute to the limited amount of published literature on the topic. Future investigations should include a greater number of companies to better represent ENM workplaces and a direct access to industrial settings to collect information on site. Finally, deeper attention should be paid to define standardized frameworks for ENM risk assessment that may guide nano-specific preventive actions.

Objectives The authors studied the correlation between the grading TIP which evaluates three otoendoscopic characteristics of the tympanic membrane (TM) (transparency, integrity and position) with the gold standard represented by the impedenzometry. Methods and materials Cross-sectional studies with independent and blind comparison with the gold standard diagnostic. The setting was primary care and ambulatory. 115 TMs were examined (57 right and 58 left) of 60 children (36 males and 24 females) and classified according to the TIP grading (transparency, integrity, position). Each patient underwent otoendoscopy to obtain TIP grading and subsequently to tympanometry, which was considered the gold standard for diagnosis. The Transparency is the condition in which at least one or more structures behind the TM are visible: promontory, incudo-malleolar and incudo-stapedial articulations. The Integrity is such when no holes in the TM are visible. The TM must be displayed up to the anulus. The position of the TM is evaluated according to the handle and the short apophysis of the malleus. The correlation between TIP grade and tympanometry was measured by the “Chi Square” test. Results The method showed an average sensitivity and specificity of the three TIP parameters (TIP1 TIP2, TIP 4) versus tympanometry of 95.6% (I.C. 90.1–98.5); PPV and PPN 95.6 (I.C 90.3%–98.1%) Positive Likelihood Ratio 22,000 (I.C. 9.327 to 51.894) Negative Likelihood Ratio 0.045 0.019 to 0.107. Conclusion Grading TIP is a valid method for accurate diagnosis of pediatric otitis media and can predict the tympanometry result with high statistical significance.

After an initial skepticism, minimally invasive liver surgery (MILS) gained popularity and is nowadays a consolidated option in specialized centers for the surgical treatment of selected patients affected by both benign and malignant liver diseases. Nevertheless, the role of MILS in the surgical treatment of hepato-cellular carcinoma (HCC) developed on the background of chronic liver disease is still a matter of debate. The indications and the current evidences on MILS for HCC are discussed in this paper. MILS being less invasive and harmful for the patients proved to offer a reduction in post-operative morbidity and specific benefits have been highlighted in case of patients affected by HCC and chronic liver disease. In fact, by minimizing liver manipulation and mobilization and by preserving the collateral blood and lymphatic flow, MILS seems to reduce the incidence of post-operative ascites and post-operative liver failure without compromising the oncologic outcomes. This has been confirmed by an analysis of 21 comparative studies and 5 metanalyses comparing MILS and open surgery for HCC. With an adequate surgical training, MILS for HCC can be undertaken safely even in case of major hepatectomies and technically demanding operations such as resections of posteriorly located tumors proved to be feasible in specialized centers. Therefore, with an appropriate patients' selection, MILS for HCC is becoming the preferred option for the surgical treatment of HCC in cirrhotic patients.

Isolated hepatic splenosis is a rare but possible condition in abdominal surgery. At radiological imaging liver splenosis mimics malignant or pathological condition of the liver; obtaining a certain diagnosis prior to surgery is difficult. For this reason, the patients undergo to unnecessary operation, with a laparotomy access. We report a case of suspicious liver mass removed laparoscopically and revealed as hepatic splenosis.A 31 years old man patient was admitted to our Institution because of upper chronic abdominal pain. Thirteen years before the recovery the patient was operated of splenectomy with laparotomic incision. Computerized Tomography and Magnetic Resonance demonstrated the presence of suspicious hepatic mass in the III segment.The mass has been radically excised with laparoscopic approach. Postoperative stay was good and patient was discharged seven day after the operation. At histological examination ectopic splenic tissue on liver surface was found (socalled splenosis).Hepatic splenosis is not a rare condition and should be considered with the differential diagnosis especially in patients who had previous splenectomy and absence of liver cirrhosis. Laparoscopic exploration should always be preferred for the diagnosis of uncertain liver mass. Few works report laparoscopic excision for liver splenosis. For experience at our Institution laparoscopic procedure has an important role to get the diagnosis and it is also a feasible approach for minimally invasive resection.Laparoscopy, Liver, Splenosis.La splenosi epatica isolata è una condizione rara ma possibile in chirurgia addominale. All’ imaging radiologico la splenosi epatica mima una neoplasia o una condizione patologica del fegato; ottenere una diagnosi certa prima dell’intervento chirurgico è difficile. Per questo motivo, i pazienti possono essere sottoposti ad operazioni inutili, con accesso laparotomico.Un uomo di 31 anni è stato ricoverato presso il nostro Istituto a causa di un dolore cronico nel quadrante superiore dell’addome. La Tomografia Computerizzata e la Risonanza Magnetica hanno dimostrato la presenza di una massa epatica sospetta al III segmento.La massa è stata asportata radicalmente con approccio laparoscopico. La degenza postoperatoria è stata buona e il paziente è stato dimesso sette giorni dopo l’operazione. L’esame istologico ha rilevato la presenza di tessuto splenico ectopico sulla superficie epatica ( splenosi).La splenosi epatica non è una condizione rara e dovrebbe essere considerata in diagnosi differenziale specialmente in pazienti che hanno subito una splenectomia e in assenza di cirrosi epatica. L’esplorazione laparoscopica andrebbe sempre preferita per la diagnosi di una massa epatica sospetta. Pochi lavori riportano l’asportazione di splenosi epatica per via laparoscopica. Secondo l’esperienza del nostro Istituto la procedura laparoscopica ha un ruolo importante per ottenere la diagnosi ed risulta un approccio valido per eseguire resezioni epatiche.

Although multiple groups have reported initial success with single port laparoscopy, no consensus exists concerning the technical aspect of this surgery. In this report, we describe in detail our technique to perform single port laparoscopic cholecystectomy. Twelve cases of single port laparoscopic cholecystectomy for gallbladder stones were performed in our surgical unit. There was only one conversion during the first operation of the series to standard laparoscopy, and never to open operation. No intraoperative adverse events or major perioperative complications were reported. All the patients have been discharged within 48 hours, with uneventful postoperative course, nearly painless, without any discomfort and no visible scar. Single port laparoscopic surgery is a promising option for the treatment of gallbladder stones providing that technical and oncological surgical principles are respected.

Recurrence of cancer and the need for several surgical treatments are the Achilles’ heel of the treatment for hepatocellular carcinoma (HCC) in cases of cirrhosis. The difficulty of reintervention is increased by the formation of adhesions after the previous hepatectomy that can make a new surgical procedure more difficult and less safe. With a minimally invasive approach, the formation of postoperative adhesions seems to be minimized, and the adhesiolysis procedure seems to be faster and safer in terms of blood loss and risk of visceral injuries. This report describes a series of 15 patients submitted to a laparoscopic reintervention (hepatic resection or radiofrequency ablation) for a recurrence of HCC after a previous open (group 1) or laparoscopic (group 2) procedure for a primary tumor. It aims to explain the feasibility, safety, and results of repeated laparoscopic liver surgery. The rates for overall postoperative mortality and morbidity were respectively 0% and 26.6% (4/15). No patients had a severe postoperative complication. Only one patient in group 2 presented with moderate ascites postoperatively, whereas two patients in group 1 reported atelectasis requiring physiotherapy and one experienced pneumonia, which was treated with antibiotics. In this series, the findings indicated that patients submitted first to an open hepatic resection (group 1) experience more intraabdominal adhesions. Moreover, in group 1, hypervascularized adhesions typical of cirrhotic patients were several and thicker, with a major potential risk of bleeding and bowel injuries at the time of reintervention. Although for group 2 the length of the intervention was shorter, for group 1, the operating times and safety in terms of bowel injuries were acceptable, demonstrating the feasibility of iterative laparoscopic surgery also for cirrhotic patients previously treated by the open surgical approach. The operative time for the second surgical procedure was shorter and the adhesiolysis easier for the patients previously treated with the laparoscopic approach (group 2). This underscores the advantages of the minimally invasive approach for managing the long oncologic history of cirrhotic patients. Laparoscopic redo surgery for recurrent HCC in cirrhotic patients is a safe and feasible procedure with good short-term outcomes, but further prospective studies are needed to support these results.

Objective To evaluate the use of multiple displacement amplification (MDA) for whole genome amplification in the preimplantation genetic diagnosis (PGD) of X-linked adrenoleukodystrophy. Design MDA was used to amplify the whole genome directly from a single blastomere. MDA products were used for polymerase chain reaction (PCR) analysis of two polymorphic markers flanking the ABCD1 gene and a new X/Y marker, X22, to sex embryos in an X-linked adrenoleukodystrophy PGD program. Setting Fertility and gynecology private center in Alicante, Spain. Patient(s) A couple in which the wife is a carrier of the ABCD1 gene mutation (676A→C) that was previously identified in her family. Intervention(s) MDA of single blastomere and PCR tests for PGD. Main Outcome Measure(s) The ability to analyze single blastomeres for X-linked adrenoleukodystrophy using MDA. Result(s) The development of an MDA-PGD protocol for X-linked adrenoleukodystrophy allowed for the diagnosis of five embryos. These were biopsied on day 3 of culture and analyzed. One embryo was an affected male and one embryo was a female carrier. Three healthy female embryos were transferred 48 hours after biopsy. Unfortunately, no pregnancy was achieved. Conclusion(s) The MDA technique is useful for overcoming the problem of insufficient genomic DNA in PGD and allows the simultaneous amplification of different targets to perform a diagnosis of any known gene defect and a sexing test by standard methods and conditions.

Liver surgery, especially for cirrhotic patients, is one of the last areas of resistance to progress in laparoscopic surgery. This study compares the postoperative results and the 2-year patient outcomes between laparoscopic and open resection for hepatocellular carcinoma in patients with histologically proven cirrhosis.From May 2000 to October 2004, 23 consecutive cirrhotic patients who underwent laparoscopic hepatectomy (LH) for HCC were compared in a retrospective analysis with a historic group of 23 patients who underwent open hepatectomy (OH). The two groups were well matched for age, gender, American Society of Anesthesiology (ASA) class, tumor location and size, type of liver resection, and severity of cirrhosis. The selection criteria for both groups specified a small (size5 cm), exophytic, or subcapsular tumor located in the left or peripheral right segments of the liver (II-VI segments, Couinaud); a well-compensated cirrhosis (Child-Pugh A); and an ASA score lower than 3. In the LH group, 15 subsegmentectomies, 3 segmentectomies, and 5 left lateral sectionectomies were performed, as compared with 12 subsegmentectomies, 5 segmentectomies, and 6 left lateral sectionectomies in the OH group.One patient in the LH group (4.3%) underwent conversion to laparotomy for inadequate exposition. The mean operative time was statistically longer for the LH group (LH, 148 min; OH, 125 min; p = 0.016), whereas blood transfusions (LH, 0%; OH, 17.3%; p = 0.036), Pringle maneuver (LH, 0%; OH, 21.73%; p = 0.017), mean hospital stay (LH, 8.3 days; OH, 12 days; p = 0.047), and postoperative complications (LH, 13%; OH, 47.8%; p = 0.010) were significantly greater in OH group. There was no statistically significant difference in mortality and 2-year survival rates between the two groups.This study shows that LH for HCC in properly selected cirrhotic patients results in fewer early postoperative complications and a shorter hospital stay than the traditional OH. The 2-year survival rate was the same for LH and OH.

Background/aims: Pyogenic liver abscess (PLA) is a rare but potentially fatal condition if untreated. In available retrospective series successful rate of per- cutaneous drainage (PD) on large multiloculated PLA, that has been definited "complex". In this observation- al study, we report the experience of our Institution in performing laparoscopic drainage of complex liver ab- scess over a 5-years period as first line treatment for selected cases of PLA. Methodology: All cases of large multiloculated liver abscesses admitted to the General and Hepatobiliary Surgery of "Loreto Nuovo" Hospital Naples, Italy over the last 5-years period were treated by laparoscopic drainage and his clinicopathological variables were retrospectively reviewed.Ten patients with large multiloculated liver abscess has been admitted and treated by only laparoscopic drainage without need of other perioperative procedures. Mean age was 51.5 years (range 41-75y); average hospital stay was 4.6 days (range 2-6 days) and major postoperative morbidity or deaths were not registered. Successful rate was 100% with no recurrence at 2-years follow up (range 12/38 months).Laparoscopic drainage seems to be a safe and reproducible mini-invasive treatment of complex liver abscesses and to offer advantages over percutaneous and surgical open approach.

Introduction Single port access laparoscopic redo liver resection for hepatocellular carcinoma on cirrhosis through a single transumbilical skin incision has not been reported in the literature so far. Methods A wedge resection of segment III lesion with a laparoendoscopic single site surgical incision is described in detail analyzing the technical aspects of the procedure. Results There were no intraoperative complications with no intraoperative or perioperative blood transfusions. A Pringle maneuver was not used. Operating time was 130 minutes. The patient had an uneventful postoperative course and was discharged on the second postoperative day. The surgical resection margin was not invaded and had a width of 1.8 cm. Conclusions In this case report, we found that liver resection performed by laparoendoscopic single site surgery for peripherally located hepatocellular carcinoma on cirrhosis seems a feasible technique. Such technique is technically demanding and should be undertaken only with proper training and in high volume centers, by surgeons with expertize in both liver and advanced laparoscopic surgery.

Previous studies comparing open distal pancreatectomy (ODP) and laparoscopic distal pancreatectomy (LDP) have found advantages related to minimal-access surgery. Few studies have compared direct and associated costs after LDP versus ODP. The purpose of the current study was to compare perioperative outcomes of patients undergoing LDP and ODP and to assess whether LDP was a cost-effective procedure compared with the traditional ODP. A retrospective analysis of a prospectively maintained database of 52 distal pancreatic resections that were performed during a 10-year period was performed. Patients included in the analysis were 16 in the LDP group and 29 in the ODP. Tumors operated laparoscopically were smaller than those removed at open operation, but the length of pancreatic resection was similar. The mean operating time for LDP was longer than ODP (204 ± 31 vs. 160 ± 35; P

Incidentally detected early gallbladder cancer (IDEGB) is an early carcinoma first diagnosed on microscopic examination after a cholecystectomy for symptomatic benign gallbladder disease. After diagnosis of IDEGB it is often necessary a completion of treatment by a second tailored revision procedure. Despite early reports contraindicating laparoscopic approach because of high risk of neoplastic seeding, recent data seem to demonstrate that this approach per se does not influence clinical outcomes. We refer our experience in revision surgery by a totally laparoscopic approach that includes hepatic resection, lymphadenectomy, and port-sites excision.From January 2006 to March 2008, four patients with IDEGB were carried out to revision procedure by a totally laparoscopic approach. The mean operative time of procedure has been 162 minutes, whereas blood loss has been100 mL (mean 85.1±23.3 mL). The postoperative course has been uneventful in all patients and perioperative mortality (within 40 days from intervention) 0. Hospital stay has been, respectively, 4, 5, 5, and 6 days (mean 5 days). During follow-up, at the last fluorine-18-labeled fluordesoxyglucose-positron emission tomography (FDG-PET) scan examination, respectively, 4, 3, and--for 2 patients--2 years after revision laparoscopic procedure, pathologic FDG accumulation was not reported.Totally laparoscopic revision surgery for IDEGC seems to be a legitimate procedure, and, in our experience, reports satisfactory clinical outcomes in terms of perioperative and middle term oncological results. Larger and prospective studies are needed to support definitively oncological safety of this approach.

Background Few studies have compared survival and recurrence rates between laparoscopic and open liver resection for hepatocellular carcinoma in patients with cirrhosis. Methods A retrospective analysis of a prospectively maintained database of 179 liver resections performed for HCC in cirrhotic liver between 2000 and 2007 was performed. Results Fifty-four patients underwent a laparoscopic resection and 125 patients had open surgery. Histopathological features were largely comparable in the two groups. Tumours operated laparoscopically were smaller than those removed at open operation and laparoscopic liver resection was less extensive. Laparoscopic surgery had a lower morbidity rate than open surgery (19 versus 36·0 per cent; P = 0·020), whereas 30-day mortality was similar (2 versus 4·0 per cent; P = 0·615). After a median follow-up of 24 months, 1- and 3-year survival rates were 94 and 67 per cent in the laparoscopic group. Recurrence rates were similar after laparoscopic and open procedures (45 versus 52·5 per cent; P = 0·381), as was disease-free survival (P = 0·864). Conclusion Laparoscopic resection of HCC in cirrhotic liver is feasible and safe in selected patients. Adequate long-term survival and recurrence is achieved compared with open surgery, when stratified for tumour characteristics known to be related to survival outcome.

Hemangioma is the most frequent focal liver lesion. It affects mainly women and may cause symptoms such as abdominal pain, mass, and early satiety, or complications such as heart failure or coagulopathy (Kasabach-Merrit syndrome). Although, surgical resection is the only curative treatment for symptomatic giant hemangiomas, the best surgical technique (formal liver resection or enucleation) is still debated. Between January 2000 and April 2006 we treated 12 giant symptomatic hemangioma. Of these, 4 anterior and superficially located in the liver were treated by enucleation and they are discussed in this paper. The operative technique is described. Detailed pathologic examination has demonstrated an interface between hemangiomas and the normal liver tissue that allowed the enucleation. The dissection in the plane between the tumor and the adjacent normal liver tissue has been facilitated by the use of an ultrasonically activated device (USAD). Median operative blood loss was 90 ml (range, 50 to 190 ml), and no transfusion were used. The procedure described allowed a safe enucleation of giant hemangiomas with a reduced blood loss and the preservation of virtually all normal hepatic parenchyma.

Laparoscopic hepatectomy is a promising option for patients affected by a liver mass, and the procedure is gaining popularity. Minor laparoscopic resections have been widely reported. In contrast, major laparoscopic hepatectomy has been performed in only a limited number of cases. Hand-assisted laparoscopic liver surgery has been advocated in order to improve liver exposure and vascular control and increase the safety of the procedure. Transparenchymal en-bloc transection of the right portal triad has been reported to be safe and useful in open surgery.We describe a personal technique for hand-assisted right hemihepatectomy. With ultrasound guidance, the right hepatic pedicle is isolated intrahepatically and transected en bloc with a single firing of an endostapler. Parenchymal transection is carried out with ultrasonically activated or vessel-sealing devices together with endostaplers.The procedure was successfully accomplished in three patients. The Pringle maneuver was never performed. No intraoperative or postoperative complications occurred.This study is the first to report a technique of right hemihepatectomy that combines hand-assisted laparoscopy and an ultrasound-guided intrahepatic approach. This technique may be a useful option to simplify the operation, reduce operative time, and increase the safety of the procedure.

Laparoscopic technique for lesions located in the left liver is well described in the literature. On the contrary, the best laparoscopic approach for lesions located in the right liver, such as in segment VI, is still debated. In this article, we provide a detailed description of a laparoscopic segment VI liver resection using a left lateral decubitus position with the right side up, facilitated by a personal technique. We also discuss potential advantages and disadvantages of this procedure.

The management of patients affected by more than one hepatocellular carcinoma (HCC) is still controversial but nowadays a multimodal approach to this pathology seems to be the most effective and versatile therapeutic option. When orthotopic liver transplantation is not indicated, survival-time and quality of life improvement is the goal for patients who will have a long metabolic and oncologic disease history. Combined use of minimally invasive nonsurgical treatments [percutaneous ethanol injection, radiofrequency ablation, transcutaneous arterial chemioembolization (TACE)] allows to offer to the patients the advantages of each therapeutic procedure reducing their individual side effects and complications. We consider laparoscopy as a minimally invasive procedure, which can offer the benefits of surgical treatment, by tumor removing, but with an improved postoperative course. If recurrence risk factors are present, the costs/benefits rapport can be decreased by the laparoscopic approach which offers, in addition to a radical resection, a decreased postoperative pain, reduced trauma to the abdominal wall, smaller incisions, reduced peritoneal adhesions and, in selected cases, an earlier beginning of chemiotherapy. We report the case of a patient affected by more than one HCC with a bigger lesion of 50 mm protruding from hepatic segment III, one subcapsular lesion located at segment V, and one deep lesion located at segment VII-VIII. The patient was submitted to a double laparoscopic liver resection in association with laparoscopic radiofrequency ablation. Five months later, the patient presented an early recurrence of malignancy that was treated by TACE. At 8 months from the treatment, the patient presented another multifocal recurrence and was submitted to another TACE. At 2 years from the laparoscopic procedure, the patient is in apparent good conditions with an acceptable quality of life. We think that laparoscopic resection could gain a considerable place in the multimodal treatment of cirrhotic liver with more than one HCC because, by tumor removing, it offers the benefits of surgical treatment with a lower complications rate.

Background Traditional approach to incisional hernias (IHs) in cirrhotic patients is plagued by a significant recurrence rate and frequent wound infections. The laparoscopic repair of IHs was designed to offer a minimally invasive and tension-free technique that yields less morbidity and fewer recurrences than the standard open repair. In cirrhotic patients there are additional reasons for the benefits of laparoscopy. First, preservation of the abdominal wall avoids interruption of large collateral veins. Second, nonexposure of viscera restricts electrolytic and protein losses, and improves absorption of ascites. Finally, the laparoscopic approach is associated with a lower perioperative blood loss (smaller abdominal incision). Methods A retrospective review was performed for 14 consecutive patients with ventral hernias and affected by chronic hepatitis or cirrhosis related to hepatitis C-B virus, who underwent laparoscopic repair at our institution between September 2002 and October 2004. All patients were in class A of Child-Pugh classification. Results There was no conversion to open operation. The mean size of the defects was 87 cm2 (range 1 to 480); incarceration was present in 2 patients and multiple (Swiss-cheese) defects in 1. In all cases, the mesh (average, 287 cm2) was secured with transabdominal sutures and metal tacks or staples leaving the sac in situ. Operative time and estimated blood loss averaged 88 min (range 18 to 270) and 30 mL (range 10 to 150). Length of hospital stay averaged 2.6 days (range 1 to 6). There were 11 minor complications: seroma lasting >4 weeks (5), postoperative ileus (2), suture site pain >2 weeks (2), urinary retention (1), and skin breakdown (1). We experienced no recurrences with an average follow-up of 8 months (range 3 to 24). Conclusions Laparoscopic IH repair is technically feasible and safe even in cirrhotic patients with fascial defects. This operation decreases postoperative pain, shortens the recovery period, and seems to reduce postoperative morbidity and recurrence. To the best of our knowledge, this is the first report in which a series of cirrhotic patients affected by incisional and umbilical hernias is treated with a laparoscopic approach.

Laparoscopy for liver resection is highly specialized field because laparoscopic liver surgery presents severe technical difficulties, such as control of bleeding and risk of gas embolism. At present, a limited number of laparoscopic anatomical left lobectomies have been reported in the literature, but we believe that the use of stapling devices has made this technique safer and faster.From January 2000 to May 2005, eight patients (five men, three women; mean age, 60.5 years) underwent laparoscopic anatomical left lobectomy at our department. Seven patients presented with hepatocellular carcinoma and cirrhosis, while one patient had a large symptomatic angioma. The average size of the lesions was 4.18 cm (range, 3.6-7.1 cm); all the lesions were localized in the anatomical left lobe (segments II-III). Transection of the liver parenchyma, together with sectioning of the vascular pedicle for segment II and III and of the left hepatic vein, was obtained by the use of stapling devices.The mean operative time was 142 min (range, 120-180 min). There were no intraoperative or postoperative complications, and blood transfusions were not required. The mean postoperative hospital stay was 5.75 days.The key points of the technique are: late mobilization of the liver; no transection of the round ligament; no surrounding or taping of the portal pedicles or of the left hepatic vein; and the use of three consecutive linear staplers, turned to the left for transecting the liver parenchyma and vascular pedicle together. This technique, in our opinion, should be considered a new good option for patients with isolated lesions of the left lateral segments, but it must be performed by surgeons trained in both liver and advanced laparoscopic surgery.

In the belief that the advantages stemming from a minimally invasive approach are significant, particularly in cirrhosis patients, we decided to apply this technique in the treatment of a group of patients suffering from HCC associated with cirrhosis. Sixteen patients (10 men, 6 women; mean age 60.1 years) underwent laparoscopic surgery for HCC associated with well compensated HCV-related liver cirrhosis (Child-Pugh class A; mean tumour size 2.9 cm). Seven of these lesions were located in the left liver and 9 in the right lobe. Laparoscopy was performed with a CO2 pneumoperitoneum (12-14 mmHg). The Pringle manoeuvre was not used. There was one conversion to laparotomy due to inadequate exposure. We performed 13 non-anatomical resections, 1 VI segmentectomy and 1 anatomical left lobectomy. None of the patients required blood transfusions. One patient died of severe respiratory distress syndrome on postoperative day 3. Major morbidity included 2 moderate postoperative ascites successfully resolved with conservative treatment. To date (mean follow-up: 18 months) no recurrences at the resection site or port-site metastases have been observed. Limited laparoscopic liver resections for HCC in cirrhotic patients are technically feasible and safe when careful selection criteria are adopted (hepatic involvement limited and located in the left or anterior right segments, tumour size smaller than 5 cm, Child-Pugh class A).
