To investigate the prognostic role of procalcitonin (PCT) assessment and blood culture (BC) acquisition in the emergency department (ED) in patients with urinary tract infection (UTI) or urosepsis. We enrolled patients admitted for UTI to our ED over a 10-year period. Mortality and in hospital length of stay (LOS) were compared between patients with UTI or urosepsis who had sampling for PCT levels and BC taken in the ED (ePCT group-eBC group) and those who had not (no-ePCT group-no-eBC group). 1029 patients were analyzed, 52.7% of which were female. Median age was 77 [65-83]; 139 patients (13.5%) had complicated UTI. Median LOS was 10 [7-17] days. In the ePCT group, LOS was 10 [7-16] days, vs. 10 [7-17] (p = 0.428) in the no-ePCT group. In the eBC group, LOS was 10 [6-16] days vs. 10 [7-17] days (p = 0.369) in the no-eBC group. The overall mortality rate was 6.6%. The mortality rate was not affected by early PCT determination (6% in the ePCT group vs. 6.9% in the no-ePCT group, p = 0.584). Similarly, the mortality rate was not different in the eBC group as compared to the no-eBC group (5.4% vs. 6.9%, p = 0.415). Performance of ePCT or eBC testing made no significant difference in terms of improvement of mortality rates in septic patients (11.4% vs. 7.2%; p = 0.397 and 8.8% vs. 9.8%; p = 0.845, respectively). The prognostic relevance of early evaluation of PCT and BC in the ED of patients with febrile UTI appears limited. In complicated UTI patients, PCT and BC testing may be more appropriate in the context of improving antibiotic stewardship, or as an integral component of PCT-guided standardized protocols.

Background Mild traumatic brain injury (TBI) in anticoagulated patients is a common challenge for emergency departments because of lack of appropriate epidemiological data and huge management variability for those under oral anticoagulation therapy. Given the discrepancies between guidelines, the aim of the present study was to quantify the association between oral anticoagulant therapy (either vitamin K antagonist (VKA) or direct oral anticoagulant (DOAC)) and the post-traumatic intracranial hemorrhage worsening compared to admission CT scan. Methods We included all consecutive records of patients admitted to our emergency department for mild TBI as chief complaint and with a positive admission CT scan. After statistical univariate comparison, cause-specific hazard ratio (HR) and 95% confidence interval (CI) were determined with the use of Cox proportional hazard model. Results In the study period, 4667 patients had a CT scan for mild TBI; 439 (9.4%) were found to have intracranial hemorrhage. Among these patients, 299 (68.1%) were prescribed observation and control CT: 46 (15.38%) were on anticoagulant therapy, 23 (50%) on VKA, and 23 (50%) on DOAC. In multivariate analysis, only oral anticoagulation therapy was significantly associated to an increased risk of intracranial hemorrhage progression (HR 2.58; 95% CI 1.411-4.703; p = .002 and HR 1.9; 95% CI 1.004-3.735; p = .0048 for VKA and DOAC, respectively). Surgery was due to isolated subdural hematoma in 87.5% of cases, to subdural hematoma associated with intraparenchymal hemorrhage in 9.38% and to intraparenchymal hemorrhage only in 3.12%; 13 cases (4.35%) deceased in intensive care unit. Conclusions In our series, anticoagulation was associated to a significant increase in intracranial progression, leaving the question open as to what this implies in current clinical practice; subdural hematoma was the major finding associated to evolution and surgery. Against this background, further studies are needed to clarify patients' management and DOAC safety profile compared to VKA in mild TBI.

Introduction Well recognized guidelines are available for the use of cranial computed tomography (CCT) in traumatic patients, while no definitely accepted standards exists to for CCT in patients without history of head injury. The aim of this study is to propose an easy clinical score to stratify the need of CCT in emergency department (ED) patients with suspect non-traumatic intracranial pathology. Methods We retrospectively evaluated patients presenting to the ED for neurological deficit, postural instability, acute headache, altered mental status, seizures, confusion, dizziness, vertigo, syncope, and pre-syncope. We build a score for positive CCT prediction by using a logistic regression model on clinical factors significant at univariate analysis. The score was validated on a population of prospectively observed patients. Results We reviewed clinical data of 1156 patients; positivity of CCT was 15.2%. Persistent neurological deficit, new onset acute headache, seizures and/or altered state of consciousness, and transient neurological disorders were independent predictors of positive CCT. We observed 508 patients in a validation prospective cohort; CCT was positive in 11.3%. Our score performed well in validation population with a ROC AUC of 0.787 (CI 95% 0.748–0.822). Avoiding CT in score 0 patients would have saved 82 (16.2%) exams. No patients with score 0 had a positive CCT findings; score sensitivity was 100.0 (CI 95% 93.7–100.0). Conclusions A score for risk stratification of patients with suspect of intra-cranial pathology could reduce CT request in ED, avoiding a significant number of CCT while minimizing the risk of missing positive results.

Laparoscopic approach is now generally accepted for the treatment of incisional hernia. The ideal mesh is still to be found. The aim of this study is to compare the well-known Gore® DUALMESH® Plus (WL GoreAssociates, Flagstaff, AZ) to a new prosthesis, the DynaMesh®-IPOM (FEG Textiltechnik GmbH, Aachen, Germany), to clinically verify its potential benefits in the laparoscopic treatment of incisional hernia.Comparing the results of the laparoscopic treatment of two groups of patients affected by incisional hernia using Gore® DUALMESH® Plus and DynaMesh®-IPOM.There were 45 females and 31 males, with age variable from 21 to 84 years of age. The two groups were well matched for age (median age 60 years for group A and 57.6 years for group B-p=0.44) and sex (28F and 17M group A and 13 F and 18 M group B-p=0.008), while median BMI resulted slightly higher in group B (26.12 group A and 29.74 group B-p=0.001). The median size of the defect was similar in the two groups (87.5 mm group A and 83.4 mm for group B-p=0.83), while the median operating time was slightly longer in group A (77 min group A and 67 min group B-p=0.44). No difference in the length of hospital stay was evidenced between the two groups (3.19 days for group A and 3 days for group B-p=0.74). Time to return to physical activity was similar between the two groups (13.46 days for group A and 12.7 days for group B-p=0.32). Minor complications occurred in 15 cases (19.7%): seromas (7 cases), prolonged ileus (6 cases), and hemoperitoneum (2 cases), without significant difference in the incidence of such complications in the two groups. Five recurrences (6.5% of cases) occurred. No differences in the recurrence rate was noted between the two groups (3 cases/7% for group A and 2 cases/6% for group B-p=00.7).DynaMesh®-IPOM proved to be a safe and effective mesh for the laparoscopic repair of incisional hernia even when compared to DUALMESH® Plus.

Background Our objective was evaluate the outcome of primary clinical T4M0 extraperitoneal rectal cancer treated by neoadjuvant radiochemotherapy. Prognosis of clinical T4 rectal cancer is poor. Preoperative chemoradiation therapy may be beneficial. The results obtained are unclear due to lack of objective and strictly applied staging methods. Methods Patients with primary, clinical, T4MO, extraperitoneal rectal cancer, defined by transrectal ultrasonography, computed tomography or magnetic resonance imaging, were considered. Intraoperative radiotherapy and adjuvant chemotherapy were employed in some patients after curative resection (R0). Variables influencing the possibility to perform an R0 resection and a sphincter-saving procedure were investigated as predictors of outcome. Results 100 patients were included. R0 resection was performed in 78 patients. R0 resection rate was greater in females (93% vs 67%) and in responders to neoadjuvant chemoradiation (94% vs 60%). The ability to perform a sphincter-saving procedure was 57%, greater in middle rectal location (85% vs 51%) and in responders to the chemoradiation (70% vs 47%). Median follow-up was 31 months (range, 4–136). Local recurrences were found in 7 patients (10%). Five-year local control in R0 patients was 90% and better in the IORT group (100%). Distant relapse occurred in 24 patients (30%). Five-year overall survival was 59%, and was better after an R0 versus an R1 or R2 resection (68% vs 22%). Overall and disease free survival in R0 patients improved after overall downstaging. Adjuvant chemotherapy given in addition to the neoadjuvant therapy did not appear to offer benefit in improving survival. Conclusion A multimodal approach enabled us to obtain a 5-year overall survival of about 60%. IORT increased local control. The role of adjuvant chemotherapy needs to be further investigated.

The long-term results after stapled hemorrhoidopexy compared with Milligan-Morgan procedure are discussed. The clinical data of 100 patients treated by Milligan-Morgan procedure or stapled hemorrhoidopexy for fourth-degree hemorrhoids have been reviewed. All patients were visited and submitted to a questionnaire to evaluate resumption of symptoms, functional results, and recurrence rate. The mean follow-up was 54 months for stapled hemorrhoidopexy and 92 months for the Milligan-Morgan procedure. Postoperative pain and return to normal activity were worse in the Milligan-Morgan procedure (Visual Analog Scale 8.56 vs. 5.46, P-lt;-.001; and 2.4 vs. 2 weeks, P value--.018). Eight percent of patients who had stapled hemorrhoidopexy complained of spontaneous pain or pain during defecation vs. 0 percent of patients who underwent the Milligan-Morgan procedure. We noted that there was bleeding in 14 percent of stapled hemorrhoidopexy vs. 0 percent of Milligan-Morgan procedure (P-lt;-.006), tenesmus in 32 percent of stapled hemorrhoidopexy vs. 0 percent of Milligan-Morgan procedure (P-lt;-.001), and pruritus in 4 percent of stapled hemorrhoidopexy vs. 0 percent of Milligan-Morgan procedure. Minor leakage was similar in the two groups. Flatus impaired control was less frequent in Milligan-Morgan. The relative risk of recurrence for stapled hemorrhoidopexy compared with Milligan-Morgan procedure was 1.18 (95 percent confidence interval 1< relative risk < 1.4). No statistical difference was noted in patients-satisfaction after the procedures. Long follow-up seems to indicate more favorable results in Milligan-Morgan procedure in terms of resumption of symptoms and risk of recurrence.

Incisional hernias are one of the most frequent complications of open abdominal surgery. The incidence of relapses after a conventional repair procedure is higher in recurrent than in primary cases (30%-50% vs. 11%-20%). The laparoscopic approach can prevent the complications associated with the conventional approach when dealing with recurrent incisional hernias. The aim of this study was to evaluate the efficacy of laparoscopic treatment in such cases.We prospectively analyzed data from 41 consecutive patients with recurrent incisional hernias, who submitted to a laparoscopic repair procedure with an expanded polytetrafluoroethylene Dual Mesh (Gore-Tex Dual Mesh Plus Biomaterial; W.L. Gore 8 Associates) from December 2001 to December 2004. All of the patients underwent clinical follow-up at 1, 6, and 12 months and then yearly. An ultrasound scan of the abdominal wall was performed at 6 and 12 months after the procedure. The parameters considered for the analysis were: mesh size, operating time, hospital stay, postoperative complications, and recurrences.The defects were usually localized along midline laparotomies. The mean mesh size was 400 cm2, the mean operating time was 68 minutes, and the mean length of hospital stay was 2.7 days. Complications were encountered in 17% of patients. The mean follow-up was 38 months (range, 18-54). Recurrence was reported in 1 case only (2.4%), which occurred within the first 6 months after the operation.The laparoscopic repair of recurrent incisional hernia seems to be an effective alternative to the conventional approach, as it can give lower recurrence and complication rates.

The aim of this study was to prospectively define and measure evacuation and continence disorders after preoperative radiochemotherapy and total mesorectal excision (TME) for rectal cancer 1 year after surgery.We submitted 100 patients, who underwent neoadjuvant treatment and anterior resection with TME from 1996 to 2003, to a questionnaire on postoperative continence and evacuation. Anal sphincter function was further assessed by the Memorial Sloan-Kettering score. Factors influencing anorectal function were examined in univariate and multivariate analysis.Median evacuation score was 16.12 +/- 5.12 (range 0-28). Sensation of incomplete evacuation was reported in 58% of cases, necessity to return to the bathroom15 min in 37% and inability to evacuate completely15 min in 35%. Median continence score was 13.7 +/- 4.79 (range 0-20). Incontinence to flatus was reported in 46% of cases. Colonic J-pouch allows better evacuation and continence. Continence was also better in absence of postoperative complications. Sphincter function resulted excellent or good in 75% of patients according to the Memorial Sloan-Kettering score.The most frequent symptoms in our series are the sensation of incomplete evacuation, the incontinence to flatus, and the necessity to return to the bathroom15 min. Colonic J-pouch warrants a better function. Postoperative complications compromise good functional results.

Aims and Background To describe and discuss, on the basis of the authors’ experience and a review of the literature, the main aspects regarding the etiology, diagnosis, treatment and prognosis of congenital tumors of the retrorectal space. Methods We present 2 cases of congenital retrorectal tumors, a sacrococcygeal teratoma and a dermoid cyst, which represent, from the pathogenetic point of view, the most frequent presentation of the rare tumors of the retrorectal space. Results The reported cases are typical. The teratoma presented as an encapsulated, mixed mass located in the pelvic cavity behind the rectum and the vaginal canal, without signs of sacral involvement. The dermoid cyst appeared as a unilocular lesion filled with sebum and hair, which extended laterally to the iliopubic branch, medially to the urethra and anal canal, and posteriorly to the adipose tissue of the right buttock. Pelvic MRI produced a precise picture of the extension of the lesion and of the relationship between the mass and the pelvic organs and surrounding bony structures. Both lesions were completely removed via the perineal approach without coccygectomy. No recurrences were observed at 2 years of follow-up. Conclusions Congenital retrorectal tumors are rare. MRI is crucial for diagnosis and preoperative planning. Complete surgical removal is the treatment of choice. Resection of the coccyx is necessary only in case of its involvement by the neoplastic mass or suspected malignant transformation.

Correlation between pathological response of primary tumour and mesorectal lymph node involvement was prospectively evaluated to assess the role of local excision (LE) in rectal cancer after complete response to neoadjuvant treatment. A series of 272 consecutive rectal cancer, submitted to neoadjuvant radiochemotherapy (RCT) and surgery with total mesorectal excision (TME) were analysed. Tumour downstaging (pT) and tumour regression grade (TRG) together with sex, age, location of the tumour, pre-treatment clinical stage, type of chemoradiation and operation performed entered in an univariate and multivariate analysis. Pathological complete response on primary tumour was found in 56 patients (20.6%). Lymph node metastases were found in 72 patients (26.5%). The rate of positive nodes was 1.8% for pT0 and TRG1 cases, respectively, to go up to 6.3% for pT1 and 24.1% for TRG 2 cases, respectively. At the univariate analysis, factors with a statistically significant correlation with the risk of lymph node metastasis were: clinical pre-treatment N stage (p

Acquired giant bladder diverticula of obstructive genesis are not particularly unusual. On the other hand, acute urinary retention due to bladder diverticula is an extremely rare event in adult patients, since most cases are paediatric. A 40-year-old white male with a history of invasive urological procedures presented with recurrent acute urinary retention. Diagnostic procedures including cystourethrography and cystoscopy revealed a giant bladder diverticulum causing ab extrinseco compression of the urethra. The iatrogenic aetiology of the vicious circle of chronic urethral obstruction and increased luminal pressure promoting diverticular growth is discussed.

Background Distant spread from breast cancer is commonly found in bones, lungs, liver and central nervous system. Metastatic involvement of peritoneum and retroperitoneum is unusual and unexpected. Case presentation We report the case of a 67 year-old-woman who presented with gastrointestinal symptoms which revealed to be the clinical manifestations of peritoneal and retroperitoneal metastatic spread of an invasive lobular breast cancer diagnosed 15 years before. Conclusion To the best of our knowledge, the case presented is the third one reported in literature showing a wide peritoneal and extraperitoneal diffusion of an invasive lobular breast cancer. The long and complex diagnostic work up which led us to the diagnosis is illustrated, with particular emphasis on the multidisciplinary approach, which is mandatory to obtain such a result in these cases. Awareness of such a condition by clinicians is mandatory in order to make an early diagnosis and start a prompt and correct therapeutic approach.

This study was designed to evaluate long-term outcome in locally advanced resectable extraperitoneal rectal cancer treated by preoperative radiochemotherapy. Eighty-three consecutive patients who developed locally advanced resectable extraperitoneal rectal cancer underwent preoperative concomitant radiochemotherapy followed by surgery, including total mesorectal excision. Median follow-up was 108 (range, 10–169) months. The living patients underwent complete follow-up of, at least, nine years. Fourteen patients developed local recurrence. The time to detection was longer than two years in eight cases and longer than five years in four. Twenty-one patients developed metastases, 19 within the first five years from surgery. At the univariate analysis, clinical stage at presentation, lymph node involvement at clinical restaging after neoadjuvant therapy, and pTand pN stage were found positively correlated to the incidence of metastases. At the multivariate analysis, the only factors which confirmed a positive correlation were pT stage and pN stage. The actuarial overall survival at five, seven, and ten years was 75.5, 67.8, and 60.4 percent, respectively. The same figures for cancer-related survival were 77.9, 70, and 65.8 percent. At the univariate analysis, factors directly correlated with worse survival were: TNM stage at clinical restaging after neoadjuvant therapy (in particular lymph node involvement) pTNM, pT, and pN. At the multivariate analysis the only factors that confirmed a correlation with worse survival were pTNM, pT, and pN. Long- term follow-up allows to individuate 28 percent of all local relapses after the first five years from surgery. Postoperative stage is highly predictive of prognosis.

The negative results in terms of morbidity, mortality and survival among emergency treated patients affected by colorectal cancer are well known. The specific contribution of emergency surgery to adverse outcome is not clear because of the presence in all series of other possible determinants of a poor prognosis. We used a case-control study design to compare a group of 50 patients operated on for cancer of the rectum and left colon presented as emergencies in our department during the last 14 years, and an equal number of patients who underwent elective procedures during the same period. All records of these patients were reviewed and matched for age, stage, tumor location, and medical comorbidities (coronaropathy, diabetes mellitus, cerebral vascular deficiency, chronic obstructive pulmonary disease). Outcome measures included length of hospital stay, morbidity, mortality, and actuarial 5-year survival. Univariate and multivariate analysis of factors potentially influencing survival was performed on the entire population of 100 patients. Age, tumor location, stage of disease, and medical comorbidities were well matched by intent of the study design. Overall surgical morbidity (44% versus 12% P = 0.0004), length of hospital stay (16, 64 versus 10, 97 days P = 0.0026) and postoperative mortality (4% versus 0% P = 0.4949) resulted higher in the emergency group. Actuarial overall 5-year survival was not different between the two groups. The only variables independently predictive of survival in multivariate analysis were age and rectal location of the tumor. Postoperative surgical mortality and long-term survival appear not to be influenced by emergency presentation of colorectal cancer; the negative impact of the emergency procedures is confined to the immediate postoperative period and is probably connected to the acute medical pathology often presented by patients in emergency situations. Dealing with this kind of patient's accurate preoperative assessment and solution of acute medical pathologies before surgical treatment are mandatory.

An umbilical nodule may be an early or late sign of metastatic spread from an internal malignancy. Usually it appears when the internal malignancy is widely disseminated and has been previously diagnosed. More rarely, such a nodule is the first sign of disease and eventually results in the diagnosis of the primary tumor. We present two cases which document examples of both events, in order to focus on the most relevant aspects of this condition.

The first description of phlegmasia caerulea dolens of the leg due to deep vein compression by a giant mesenteric cyst is presented. In particular, the authors stress the role of the drainage of the cystic mass, performed as an emergency procedure, in the rapid improvement of symptoms, prevention of complications and achievement of definitive recovery. On the basis of such unusual case, a wide review of the literature on this subject is reported, aiming to stress the most crucial aspects regarding aetiology, clinical features, complications, therapy and prognosis of this disease.

Background: The impact of preoperative use of TNF-alpha inhibitors on postoperative complications in patients with inflammatory bowel disease (IBD) is still debated. While it is mostly accepted that their preoperative use for Crohn's disease (CD) does not increase the risk of postoperative complications, the same is controversial for ulcerative colitis (UC). Aim: to evaluate the effect of anti-TNF-alpha preoperative treatment on short-term postoperative complications in patients with IBD. Materials & Methods: Medical records of patients who underwent abdominal surgery for IBD (from 2004 to 2009) after receiving TNF-alpha inhibitors within 12 weeks were analyzed and compared with a matched control group of surgical IBD patients not receiving biologics. Incidence of short-term post-operative complications within 30 days after surgery (mortality, hypomobility, bleeding requiring reoperation, anastomotic leak; infectious, thrombotic, cardiac, hepato-renal and pouchspecific complications) was recorded. Results: 104 patients (68 CD/36 UC; 65 male/39 female; median age: 39 yr, range:16-74; median duration of disease: 5 yr, range:0.5-30) were identified. 5 patients were also affected by general comorbidities (diabetes, chronic hearth disease, renal failure). 50 patients (35 CD/15 UC) were treated with anti-TNF-alpha (infliximab n=39, adalimumab n=10, certolizumab n=1) within 12 weeks prior surgery; among them, 34% and 40% were on concomitant steroids or immunosuppressants, respectively. 54 surgical patients (33 CD/21 UC) not receiving anti-TNF-alpha drugs served as controls; among them, 52% and 13% were on concomitant steroids or immunosuppressants, respectively. In the anti TNF-alpha group use of concomitant steroids was significantly higher in patients with UC (p=.012) and with extraintestinal manifestation (p=.041). 94 patients underwent elective surgery, 22 with laparoscopic approach. Median post-operative staywas 11 days (range:7-45). No post-operativemortality was recorded. Infectious complications occurred in 16 patients, hypomobility in 1, thrombotic in 1 and hepato-renal complications in 3 patients. Bleeding requiring reoperation was recorded in 3 patients and anastomotic leak occurred in 7. Hospital readmission was necessary for 9 patients. No statistically significant differences between anti-TNF-alpha and control groups were found. Infectious complications occurred on 8 anti-TNF-alpha patients and 8 controls, all of them also on concomitant steroids. Conclusion: The use of anti-TNF-alpha drugs within 12 weeks before abdominal surgery in patients with IBD does not seem associated with increased rate of cumulative postoperative complications.
