Background: Current evidence concerning bowel preparation before elective colorectal surgery is still controversial. This study aimed to compare the incidence of anastomotic leakage (AL), surgical site infections (SSIs), and overall morbidity (any adverse event, OM) after elective colorectal surgery using four different types of bowel preparation., Methods: A prospective database gathered among 78 Italian surgical centers in two prospective studies, including 6241 patients who underwent elective colorectal resection with anastomosis for malignant or benign disease, was re-analyzed through a multi-treatment machine-learning model considering no bowel preparation (NBP; No. = 3742; 60.0%) as the reference treatment arm, compared to oral antibiotics alone (oA; No. = 406; 6.5%), mechanical bowel preparation alone (MBP; No. = 1486; 23.8%), or in combination with oAB (MoABP; No. = 607; 9.7%). Twenty covariates related to biometric data, surgical procedures, perioperative management, and hospital/center data potentially affecting outcomes were included and balanced into the model. The primary endpoints were AL, SSIs, and OM. All the results were reported as odds ratio (OR) with 95% confidence intervals (95% CI)., Results: Compared to NBP, MBP showed significantly higher AL risk (OR 1.82; 95% CI 1.23-2.71; p = .003) and OM risk (OR 1.38; 95% CI 1.10-1.72; p = .005), no significant differences for all the endpoints were recorded in the oA group, whereas MoABP showed a significantly reduced SSI risk (OR 0.45; 95% CI 0.25-0.79; p = .008)., Conclusions: MoABP significantly reduced the SSI risk after elective colorectal surgery, therefore representing a valid alternative to NBP., (© 2024.

The Department of Plastic and Aesthetic Surgery, St. Anne's University Hospital in Brno, and Faculty of Medicine of Masaryk University, Brno, has a long history of surgical treatment of lymphedema and elephantiasis, which started in 1970s. There were many types of surgeries described and performed at our department - starting with prof. Bařinka's radical operation of elephantiasis, then lower limb end-to-side lymphovenous anastomosis pulled through the wall to the great saphenous vein, and genital lymphedema reduction. We call this era "the first period" of surgical lymphedema treatment. "The second period" started in 2016 by using free flaps with lymph nodes or vascularized lymph nodes and using microsurgical techniques of end-to-end, end-to-side and side-to-end lymphovenous anastomoses to the subcutaneous veins of a small calibre, which then drain the lymph into the blood stream. "The third period" started 2 years ago after the visit of prof. Yang from Taiwan - we started to use the method of single stitch end-to-side anastomosis to big subcutaneous veins like the great saphenous vein or the cephalic vein.

Perforated diverticulitis is an emergent clinical condition and its management is challenging and still debated. The aim of this position paper was to critically review the available evidence on the management of perforated diverticulitis and generalized peritonitis in order to provide evidence-based suggestions for a management strategy. Four Italian scientific societies (SICCR, SICUT, SIRM, AIGO), selected experts who identified 5 clinically relevant topics in the management of perforated diverticulitis with generalized peritonitis that would benefit from a multidisciplinary review. The following 5 issues were tackled: 1) Criteria to decide between conservative and surgical treatment in case of perforated diverticulitis with peritonitis; 2) Criteria or scoring system to choose the most appropriate surgical option when diffuse peritonitis is confirmed 3); The appropriate surgical procedure in hemodynamically stable or stabilized patients with diffuse peritonitis; 4) The appropriate surgical procedure for patients with generalized peritonitis and septic shock and 5) Optimal medical therapy in patients with generalized peritonitis from diverticular perforation before and after surgery. In perforated diverticulitis surgery is indicated in case of diffuse peritonitis or failure of conservative management and the decision to operate is not based on the presence of extraluminal air. If diffuse peritonitis is confirmed the choice of surgical technique is based on intraoperative findings and the presence or risk of severe septic shock. Further prognostic factors to consider are physiological derangement, age, comorbidities, and immune status. In hemodynamically stable patients, emergency laparoscopy has benefits over open surgery. Options include resection and anastomosis, Hartmann's procedure or laparoscopic lavage. In generalized peritonitis with septic shock, an open surgical approach is preferred. Non-restorative resection and/or damage control surgery appear to be the only viable options, depending on the severity of hemodynamic instability. Multidisciplinary medical management should be applied with the main aims of controlling infection, relieving postoperative pain and preventing and/or treating postoperative ileus. In conclusion, the complexity and diversity of patients with diverticular perforation and diffuse peritonitis requires a personalized strategy, involving a thorough classification of physiological derangement, staging of intra-abdominal infection and choice of the most appropriate surgical procedure.

Objectives: To compare overall (OS), cancer-specific (CSS), recurrence-free survival (RFS) and postoperative renal function amongst patients with upper tract urothelial carcinoma (UTUC) of the distal (lower lumbar and pelvic) ureter, electively treated with segmental resection and termino-terminal anastomosis (TT) vs bladder cuff removal and ureteric re-implantation (RR)., Patients and Methods: A multicentre retrospective study, including 84 patients diagnosed with UTUC of the distal ureter and treated with TT or RR, is presented. The primary endpoint was to compare TT and RR in terms of OS, CSS and RFS. As a secondary outcome, we compared the postoperative creatinine values as an index of renal function in the two groups., Results: Of 521 patients with UTUC, 65 (77.4%) and 19 (22.6%) patients underwent RR and TT, respectively. Pre- and postoperative characteristics were not statistically different between the two groups. The median follow-up period was 22.7 months. Patients treated with TT and those treated with RR did not have significantly different 5-year OS, CSS or RFS (73.7% vs 92.3%, P = 0.052; 94.7% vs 95.4%, P = 0.970: and 63.2% vs 53.9%, P = 0.489, respectively). No difference in postoperative creatinine variation emerged in association with the surgical technique (P = 0.411)., Conclusion: Patients treated with TT or RR for UTUC showed comparable OS, CSS, RFS and postoperative renal function. Our data suggest that bladder cuff removal is not imperative in the treatment of distal ureteric UTUC, and TT can be a safe solution in selected cases., (© 2019 The Authors BJU International © 2019 BJU International Published by John Wiley & Sons Ltd.)

Background and Aims: Bariatric surgeries such as gastric banding (LAGB), gastric bypass (RYGB), vertical banded gastroplasty (VBG), and sleeve gastrectomy (LSG) decrease body weight in morbid obesity, leading to the resolution of coexisting diabetes mellitus and arterial hypertension in the majority of cases as well as improvements of renal function and liver steatosis. BS (LAGB, RYGB, VBG, and LSG) also reduce incident cases of diabetes, of cardiovascular diseases, and of cancer; these therapeutic and preventive effects on comorbidities of obesity have not been analyzed for malabsorptive surgeries such as biliopancreatic diversion (BPD) or biliointestinal bypass (BIBP). The aim of this study was to analyze the incidence of comorbidities, i.e., diabetes, cardiovascular diseases, and cancer, in obese subjects undergoing BPD and BIBP, in comparison with standard medical treatment of obesity., Patients and Methods: Medical records of 1983 obese patients (body mass index (BMI) > 35 kg/m 2 , aged 18-65 years, undergoing surgery (n = 472, of which 111 with diabetes) or medical treatment (n = 1511, of which 422 with diabetes), during the period 1999-2008 (visit 1)) were collected; incident cases of comorbidities were ascertained through December 31, 2016., Results: Observation period was 12.0 ± 3.48 years (mean ± SD). Compared to non-surgical patients matched for age, body mass index, and blood pressure, malabsorptive surgeries were associated with reduced new incident cases of diabetes (p = 0.001), cardiovascular diseases (p = 0.001), hyperlipidemia (p = 0.001), oculopathy (p = 0.021), and cancer (p = 0.001). The preventive effect of BS was similar in both nondiabetic and diabetic patients for cardiovascular diseases and hyperlipidemia (both p = 0.001). The preventive effect was significant in nondiabetic subjects for coronary heart disease and for cancer, not significant in diabetic subjects., Conclusion: Patients undergoing malabsorptive bariatric surgery show less incident cases of diabetes, cardiovascular diseases, hyperlipidemia, oculopathy, and cancer than controls receiving medical treatment.

This article focuses on a study related to gastrectomy. This study is a multicenter prospective randomized trial from the Italian Total Gastrectomy Study Group members. The information presented attempts to answer the specific question of whether an NJT had an effect on the incidence of esophagojejunal leak. The answer presented is that NJT placement does not protect the anastomosis or the closure of the jejunum from leak, as the leak rate was the same in both groups. This fits with the bias and, therefore, is readily accepted. Leaks were documented in 8 patients in the NJT group and in 7 patients in the no-NJT group.

Biliary strictures (BS) remain a significant problem following liver transplantation (LT), representing an important cause of morbidity. The purpose of this follow-up study was to evaluate the incidence and risk factors associated with BS after LT. From 2001 to 2009, 244 consecutive patients underwent LT at our center. Multiple donor and recipient variables were collected for each patient. Exclusion criteria were hepaticojejunostomy, living-donor LT, and follow-up less than three months. We reviewed 177 patients, all of whom underwent an end-to-end choledochocholedochostomy and T-tube placement. BS occurred in 23% of patients. Multivariate analysis revealed that graft macrovesicular steatosis >25% (p = 0.05, OR 3.38) and time of T-tube removal less than six months (p = 0.02, OR 2.53) were independent risk factors for BS. Biliary strictures did not affect patient and graft survival. Donor macrovesicular steatosis represents a risk factor for BS, contributing to liver damage through a reduction in hepatic blood flow. Time of T-tube removal seems to play a role in the development of BS, although it is unclear whether it represents the cause or the consequence of the development of BS., (© 2013 John Wiley & Sons A/S.)

Bleeding is an important predictor of morbidity and mortality rates after the Bentall operation. This study reports our recent experience with composite aortic root replacement via a slightly modified button-Bentall operation. Fifty-six consecutive patients underwent a Bentall operation on an elective basis from January 2008 through December 2009. In all cases, we used 2 modifications: we imbricated the pledgeted 2-0 polyester interrupted U stitches of the proximal suture line, and at that same suture line we sealed with fibrin glue the possible sources of oozing. The series featured high proportions of associated procedures (25%) and reoperations (23%). The mean cardiopulmonary bypass and aortic cross-clamp times were 166 ± 50 and 113 ± 27 min, respectively. No case of operative or hospital (30-day) death was observed. Postoperative drainage amounted to 705 mL (median) on the first postoperative day and 377 mL (mean) on the second. Surgical re-exploration for bleeding was needed in only 1 patient (1.8%). Postoperative acute kidney injury was observed in 5 patients, neurologic complications in 3, and respiratory insufficiency requiring prolonged mechanical ventilation in another 3. Both respiratory and renal complications were significantly associated with greater consumption of blood products (P=0.03 and P=0.001, respectively). We conclude that the combined use of imbricated proximal suture-line stitches and subsequent fibrin-sealant spraying were associated with no deaths and with low rates of bleeding and other adverse postoperative sequelae in our 2-year experience with the Bentall operation in an elective series of patients characterized by a difficult mixture of prognoses.

Introduction: Biliary complications after orthotopic liver transplantation (OLT) are the principal cause of morbidity and graft dysfunction, ranging in incidence from 5.8% to 30% of cases. Biliary strictures are the most frequent type of late complication. The aim of this study was to evaluate the role of magnetic resonance cholangiography (MRC) to detect biliary anastomotic strictures among patients undergone OLT with abnormal liver function tests., Materials and Methods: One hundred twenty-one of 300 patients who underwent OLT were evaluated by MRC for clinically suspected anastomotic biliary strictures. In all patients, we performed various precholangiographic sequences including T1- and T2-weighted and MRC (radial SE 2D and SS-TSE 3D). Magnetic resonance imaging findings were subdivided as absence or presence of an anastomotic stricture. Diagnostic confirmation was obtained by endoscopic retrograde cholangiography (n=32), percutaneous transhepatic cholangiography (n=21) or surgical treatment (n=18)., Results: MRC detected 56 anastomotic biliary strictures, 53 of which were confirmed by other imaging modalities. MRC showed two false-negative cases and three false-positive cases. The sensitivity, specificity, positive and negative predictive values, and accuracy of MRC to detect biliary strictures were 96%, 96%, 95%, 97%, and 96%, respectively., Conclusion: MRC proved to be a reliable noninvasive technique to visualize the biliary anastomosis and depict biliary strictures after OLT. MRC should be used when a biliary anastomotic stricture is suspected in an OLT patient., (Copyright © 2011 Elsevier Inc. All rights reserved.)

Background/purpose: Abdominal trauma rarely causes injuries involving the duodenum and pancreas. Associated injuries occur in 46% of all pancreatic injuries. The morbidity and mortality of pancreaticoduodenal injuries remain high., Methods: The present study is a retrospective review of our experience from 1989 to 2008 in the surgical treatment of traumatic pancreaticoduodenal injuries. Mortality, morbidity, prognostic factors, and the value of surgical techniques were analyzed., Results: In our level I Trauma Center, between 1989 and 2008, 55 patients had a pancreaticoduodenal injury. In 68.5% of cases pancreatic injuries were found, 20.4% had duodenal injury, and 11.1% suffered combined pancreaticoduodenal injuries; 85.3% of the patients had blunt abdominal trauma, while 14.9% had penetrating injuries. We treated 78.1% of the patients with external drainage and/or simple suture; distal pancreatectomy was performed in 9% of cases and duodenal resection with anastomosis (3.7%) and diversion procedures (3.7%) were performed in an equal number of patients. Age, American Association for the Surgery of Trauma (AAST) grade, organ involved, hemodynamic status, intraoperative cardiac arrest, and operative time remained strongly predictive of mortality on multivariate analysis. The AAST grade represented, on multivariate analysis, the only independent prognostic factor predictive of overall morbidity. In the past decade we have used feeding jejunostomy more frequently, with a reduction of mortality and operating time, due also to a better approach from a dedicated trauma team., Conclusions: Optimal management and better outcome of pancreaticoduodenal injuries seem to be associated with shorter operative time, and with simple and fast damage control surgery (DCS), in contrast to definitive surgical procedures.

Purpose: The risk of cancer or severe polyposis of the rectal stump after total colectomy for MutYH-associated polyposis is scarcely defined. To evaluate this risk, we describe the findings of endoscopic surveillance of the rectal stump in a series of patients with biallelic MutYH mutations and polyposis., Methods: This is a retrospective, observational, multicenter case series derived from 2 familial cancer registries. Biallelic, germ-line MutYH mutations were found in 14 patients with no adenomatous polyposis coli gene mutations. Eleven of them underwent total colectomy with ileorectal anastomosis and yearly proctoscopic surveillance thereafter. Phenotype and histology of rectal polyps were recorded at diagnosis and during follow-up. Development of adenomas and carcinomas during endoscopic surveillance of the rectal stump was observed., Results: At diagnosis, 6 patients had attenuated polyposis (10-100 adenomas), 5 patients had classical polyposis, 8 patients had colon carcinoma, and no patient had rectal carcinoma. The mean number of rectal polyps at diagnosis was 2.64 ± 2.11 (range, 0-6). No patients had rectal cancer. The most frequent MutYH mutations were Y165C/Y165C and G382D/G382D in 6 and 2 patients, respectively. During surveillance of the rectal stump after surgery (median duration, 5 y; range, 2-23 y), no patient developed rectal cancer. The mean number of adenomas per proctoscopy was 1.23 ± 2.19 (range, 0-10 adenomas per proctoscopy). This study was limited by the small size and retrospective nature of the case series., Conclusion: Total colectomy with ileorectal anastomosis may be appropriate for patients with MutYH-associated polyposis, provided that they have no rectal cancer or severe rectal polyposis at presentation and that they undergo yearly endoscopic surveillance thereafter.

Objectives: Numerous devices have been successfully introduced in off-pump coronary artery bypass graft (OPCABG) surgery, most of them being disposable tools based on suction stabilization. Coronéo Cor-Vasc is a reusable system combining suction positioning with compression stabilization. The purpose of this study was to analyze our experience in OPCABG with the Cor-Vasc system., Methods: Between March 2001 and May 2008, 141 patients (age = 71.1 +/- 7.5 years) underwent OPCABG surgery using the Cor-Vasc system, representing 6.3% of the case volume of isolated coronary artery bypass graft surgery in the same period. Eighty-eight patients (62.4%) underwent surgery on an urgent basis. In 95 patients (67.4%), the OPCABG option was selected after finding a diseased ascending aorta at intraoperative epiaortic ultrasound., Results: Among 334 anastomoses (mean = 2.4 +/- 1 per patient), 242 (95 patients) were fashioned with bilateral and 54 (46 patients) with single internal thoracic artery, respectively. In 89.4 and 73% of patients, a complete and a total arterial myocardial revascularization was achieved, respectively. There were two strokes (1.4%) and two myocardial infarctions (1.4%). Two patients died in the hospital (1.4%). Median ICU and in-hospital length of stay were 31.2 h and 10 days, respectively., Conclusion: In our experience, the use of the Cor-Vasc system, including the device-learning curve, was associated with low mortality and morbidity indexes in an aged population with a high risk of stroke. The system appeared to be sufficiently versatile and potentially cost-effective when compared with disposable devices.

Background: Duodenal fistula (DF) after gastrectomy continues to be a life-threatening problem. We performed a retrospective multicenter study analyzing the characteristics of DF after elective gastrectomy for malignant disease., Methods: Three thousand seven hundred eighty-five patients who had undergone gastrectomy with duodenal stump in 11 Italian surgical units were analyzed., Results: Sixty-eight DFs occurred, with a median frequency of 1.6% and a mortality rate of 16%. Complications were mainly septic but fistulas or bleeding of surrounding organs accounted for about 30%. Reoperation was performed in 40% of patients. We observed a correlation between mortality and age (hazard ratio 1.09; 95% CI 1.00-1.20) and serum albumin (hazard ratio 0.90; 95% CI 0.83-0.99). The appearance of further complications was associated with reoperation (P < 0.001) and death (P = 0.054), while the preservation of oral feeding was related to DF healing (P < 0.001)., Conclusions: This paper represents the largest series ever published on DF and shows that its features have changed in the last 20 years. DF alone no longer leads to death and some complications observed in the past have disappeared, while new ones are emerging. Nowadays, medical therapy is preferred and surgery is indicated only in cases of abdominal sepsis or bleeding.

Objectives: To report the wide clinical experience and the research studies in the microsurgical treatment of peripheral lymphedema., Methods: More than 1800 patients with peripheral lymphedema have been treated with microsurgical techniques. Derivative lymphatic microvascular procedures recognize today its most exemplary application in multiple lymphatic-venous anastomoses (LVA). In case of associated venous disease reconstructive lymphatic microsurgery techniques have been developed. Objective assessment was undertaken by water volumetry and lymphoscintigraphy., Results: Subjective improvement was noted in 87% of patients. Objectively, volume changes showed a significant improvement in 83%, with an average reduction of 67% of the excess volume. Of those patients followed-up, 85% have been able to discontinue the use of conservative measures, with an average follow-up of more than 10 years and average reduction in excess volume of 69%. There was a 87% reduction in the incidence of cellulitis after microsurgery., Conclusions: Microsurgical LVA have a place in the treatment of peripheral lymphedema, and should be the therapy of choice in patients who are not sufficiently responsive to nonsurgical treatment., (2010 Wiley-Liss, Inc. Microsurgery, 2010.)

Purpose: To assess the influence of the method for stent placement, the duration of stenting, and the presence of bladder drainage on the complication rate of open pyeloplasty., Patients and Methods: Complications were, retrospectively, compared in 228 consecutive open pyeloplasties performed at institution A using a trans-pyelostomic 6-Fr splint/stent for 5 days and no bladder drainage, and 150 consecutive open pyeloplasties performed at institution B using a trans-nephrostomic 6-Fr splint/stent for 9 days plus bladder drainage., Results: Median age at surgery was comparable between groups. The overall complication rate was 13% and was comparable at the two institutions, but for the presence of perioperative bleeding that was more common when the stent was placed trans-nephrostomically (institution B) and the rate of stent dislodgements, which was lower at institution A, perhaps due to some technical details aiming to prevent any inadvertent traction on the stent. Additional procedures, such as double J internal stent insertion, were required in <2% of cases., Conclusions: A 5-day period of stenting after open pyeloplasty is generally enough. Trans-nephrostomic and trans-pyelostomic stent placement is equally effective. However, the former can be associated with a slightly higher bleeding rate. Details during stent placement are keys to avoid postoperative dislodgement and malfunctioning. Systematic bladder drainage seems unnecessary.

Background: Published interim results have shown that fibrin sealant (Tissucol/Tisseel Baxter AG, Vienna, Austria) may be effective in preventing anastomotic leaks and internal hernias following laparoscopic Roux-en-Y gastric bypass (LRYGBP). We report the final results of a multicenter, randomized clinical trial evaluating the use of fibrin sealant in LRYGBP., Methods: Between January 2004 and December 2005, 340 patients aged 21-65 years with a body mass index (BMI) of 40-59 kg/m(2) undergoing LRYGBP were randomized (1:1) to two treatment groups: fibrin sealant group (applied to gastrojejunal and jejunojejunal anastomoses and over mesenteric openings), and control group (no fibrin sealant; suture of the mesenteric openings). Operative time, early and late complications, reinterventions, time to oral diet initiation, and length of stay were assessed., Results: Overall, 320 patients were included into the study: 160 in the control group and 160 in the fibrin sealant group. All patients completed follow-up assessments at 6 and 12 months, and 60.9% completed assessments at 24 months. There were no significant differences between groups with respect to demographics, operative time, oral diet initiation, hospital stay, and BMI reduction at 6, 12, and 24 months. The incidence of anastomotic leak was numerically, but not significantly, greater in the control group. The overall reintervention rate for specific early complications (<30 days) was significantly higher in the control group (p = 0.016). No deaths or conversions to open laparotomy occurred., Conclusion: The use of fibrin sealant in laparoscopic RYGBP may be beneficial in reducing the reintervention rate for major perioperative (<30 days) complications. Larger studies are needed.

Background: The aim of the survey was to assess the incidence of anastomotic leaks (AL) and to identify risk factors predicting incidence and gravity of AL after low anterior resection (LAR) for rectal cancer performed by colorectal surgeons of the Italian Society of Colorectal Surgery (SICCR)., Methods: Information about patients with rectal cancers less than 12 cm from the anal verge who underwent LAR during 2005 was collected retrospectively. AL was classified as grade I to IV according to gravity. Fifteen clinical variables were examined by univariate and multivariate analyses. Further analysis was conducted on patients with AL to identify factors correlated with gravity., Results: There were 520 patients representing 64% of LAR for rectal cancer performed by SICCR members. The overall rate of AL was 15.2%. Mortality was 2.7% including 0.6% from AL. The incidence of AL was correlated with higher age (p<0.05), lower (<20 per year) centre case volume (p<0.05), obesity (p<0.05), malnutrition (p<0.01) and intraoperative contamination (p<0.05), and was lower in patients with a colonic J-pouch reservoir (p<0.05). In the multivariate analysis age, malnutrition and intraoperative contamination were independent predictors. The only predictor of severe (grade III/IV) AL was alcohol/smoking habits (p<0.05) while the absence of a diverting stoma was borderline significant (p<0.07)., Conclusion: Our retrospective survey identified several risk factors for AL. This survey was a necessary step to construct prospective interventional studies and to establish benchmark standards for outcome studies.

Objective: To describe the surgical technique and the long-term anatomic and functional results of laparoscopically assisted uterovestibular anastomosis., Design: Descriptive study., Setting: Tertiary referral center., Patient(s): Twelve consecutive patients with uterine cervix atresia and vaginal aplasia., Intervention(s): Laparoscopically assisted uterovestibular anastomosis was performed in all patients. Follow-up assessments at 1, 6, and 12 months included pelvic examination, transvaginal ultrasonography, and, in selected cases, vaginoscopy and hysteroscopy. Subsequent follow up was done by referring physicians or by means of telephone interview. Mean follow-up was 6 years., Main Outcome Measure(s): Intra- and postoperative characteristics and anatomic and functional outcome., Result(s): The surgical procedure was successful in all cases and all of the women have experienced regular menstruation. At 6-month follow-up, mean vaginal length was 6 cm and at least 80% of neovaginal epithelium was iodine-positive in all patients. Six women were sexually active during follow-up without difficulty. None have yet attempted to seek a pregnancy., Conclusion(s): The study shows the safety and effectiveness of a laparoscopic approach to uterovestibular anastomosis in women with cervical atresia and vaginal aplasia. In these patients, we believe that conservative surgery should represent the first therapeutic option. A longer follow-up is needed to assess pregnancy rates and outcome.

Purpose: We performed a retrospective evaluation and statistical analysis of outcome in patients who underwent bulbar end-to-end anastomosis., Materials and Methods: We reviewed 153 patients with an average age of 39 years who underwent bulbar end-to-end anastomosis between 1988 and 2006. Mean followup was 68 months. Stricture etiology was unknown (62.7%), catheter (14.4%), blunt perineal trauma (11.7%), instrumentation (9.8%), radiotherapy (0.7%) and infection (0.7%). Stricture length was 1 to 2 cm (in 59.5%), 2 to 3 cm (37.9%), 3 to 4 cm (1.9%) or 4 to 5 cm (0.7%). A total of 90 patients (59%) underwent dilation, internal urethrotomy, urethroplasty or multiple procedures before being referred to our center. Clinical outcome was considered a treatment failure when any postoperative instrumentation was needed. The prevalence of postoperative sexual dysfunction was investigated using a nonvalidated questionnaire., Results: Of 153 cases 139 (90.8%) were successful and 14 (9.2%) were treatment failures. Treatment failure was managed with urethrotomy in 9 cases, end-to-end anastomosis in 2, buccal mucosal graft urethroplasty in 1 and 2-stage repair in 2. Of 14 cases of failure 12 had a satisfactory final outcome, 1 is still waiting for the second stage of urethroplasty and 1 underwent definitive perineostomy. There were 14 patients (23.3%) who experienced ejaculatory dysfunction, 1 (1.6%) a cold glans during erection, 7 (11.6%) a glans that was neither full nor swollen during erection and 11 (18.3%) had decreased glans sensitivity. No patients complained of penile chordee or impotence., Conclusions: Bulbar end-to-end anastomosis has a success rate of 90.8%. Most patients were satisfied with the surgical outcome despite postoperative complications such as ejaculatory dysfunction, a glans that was neither full nor swollen during erection, or decreased penile sensitivity.

Caval anastomosis in liver transplantation has been modified to avoid outflow complications. Classic cava replacement is rarely indicated; most liver transplantation teams use a piggy-back (PB) technique. At the start of our liver transplantation program, we opted for a latero-lateral (L-L) caval anastomosis. In our prospective experience, the L-L caval anastamosis was safe and feasible in all 24 adult patients. No vascular complications occurred. Graft and patient survival rates were both 96% at 11 months follow-up.

The treatment of tumors of the distal rectum continues to be a matter of great controversy among oncologic surgeons. There are increasingly promising indications that functionally conservative surgery may be a valid therapeutic alternative to conventional therapy in patients with tumours of the lower rectum, traditionally treated by abdomino-perineal resection and definitive colostomy. Many points are presently under evaluation and we want to discuss some of the most relevant topics that are now permitting to change the guide lines of therapy of this disease. Our view of the problem is based on a personal experience cumulated in fourteen years of activity in a specialized unit and this paper reports the main results of a complex and diversified study carried out during this period at the National Cancer Institute of Milan.

Background: To avoid multiple surgeries in stenosing Crohn's disease, pneumatic endoscopic dilatation has been introduced. The present study evaluated the long-term clinical outcome in Crohn's disease patients after endoscopic dilatation for ileal or neoileal strictures., Patients and Methods: All Crohn's disease patients who underwent pneumatic dilatation of ileal or ileo-colonic strictures between January 1988 and December 2001 were invited to return for a clinical check-up in June 2002. Clinical, endoscopic and radiological reports were reviewed. Symptomatic relief from sub-occlusive symptoms without requiring surgery was considered as a positive outcome, whereas the requirement of surgery was regarded as an unfavourable outcome. Possible predictors of favourable outcome were analysed., Results: Endoscopic dilatation was technically successful in 34/43 (79%) Crohn's disease patients, with a mean number of dilatations per patient of 3 +/- 3.13. During a mean follow-up of 63.7 +/- 44.6 months, a positive long-term outcome was observed in 18 (52.9%) patients, whereas surgery was necessary in the remaining 16 cases. The risk of surgery was distinctly higher within 2 years post-dilatation than in the next 2 years (26.4% versus 8.3%, respectively; P = 0.078). No clear clinical, endoscopic or radiological predictive factors for a successful outcome were identified., Conclusions: Endoscopic pneumatic dilatation is an effective and safe procedure to be applied to patients with stenosing Crohn's disease, offering a very long-term benefit in a sub-group of patients.

Background: Anastomotic leakage after traditional surgery of the colon and rectum represents one of the more frightening complications for its high incidence (5-10%) leading to a mortality of 10-33%. The aim of the study is to analyze the main etiopathogenetic factors of this complication in the literature and, retrospectively, in personal experience., Methods: At the General Surgery Department of the Hospital of Imperia, between September 1997 and August 2001, 278 laparotomic procedures with large bowel anastomosis were completed; 37 patients (13.3%) were treated in emergency. There were 153 males (55%) and 125 females (45%), the average age being 70.5 years (range 41-94). The mean hospital stay was 12 days (range 7-45)., Results: The incidence of perioperative mortality was 1.1% (3 cases). Anastomotic leakage occurred in 4 patients (1.4%); one of these died. Analysis of the presented series confirms that factors contributing to leakage of colonic anastomoses are: distal rectum anastomoses, rectal cancer, experience of the surgeon and preoperative radiotherapy. Anastomotic leakage didn't occur in emergency, probably for a prudent attitude that considers multiple-stages surgical procedures in high-risk patients; besides a radical subtotal or total colectomy was performed in the treatment of obstructive cancer of the left colon and rectum., Conclusions: The incidence of anastomotic leakage in colo-rectal surgery was lower when anastomoses were performed in ideal circumstances; it is necessary to know the main risk factors to reduce this complication.

Background/aims: The aim of this study was to determine the best surgical approach for the treatment of late radiation injury to the bowel., Methodology: Clinical and follow-up charts of 83 patients operated in our institution for late radiation injury to the bowel were retrospectively reviewed. The type of operation (resection-anastomosis or bypass) mortality, postoperative complications and reoperation rate were recorded. Seventy-six underwent resection with immediate anastomosis. A bypass or viscerolysis was performed in only 7 patients., Results: Postoperative mortality was 2.4%, morbidity was 23. Twenty-seven patients underwent further surgery; early reoperation (within 1 month) was necessary in 12 (morbidity 41%). A late reoperation has been performed in 15 patients (no mortality, morbidity 53.5%)., Conclusions: From the results of our study it can be concluded that resection with immediate anastomosis for late radiation injury to the bowel is safe and should be the first option for these patients.

Unlabelled: Endometriosis, surgery and radiotherapy are the main causes of ureteral injuries in gynaecologic pathology., Materials and Methods: In this paper we present our experience about ureteral injuries. We treated 31 patients; 6 cases of endometriosis, 13 cases of pelvic radiotherapy for gynecologic tumors, 12 cases of ureteral injuries after gynecologic surgery. The treatments were different depending on the cause of the lesion and on the site of the lesion. In 3 cases we performed an ureteral-bladder implant with bladder psoas hitch, in 2 cases an end to end anastomosis was made. In 2 cases we made an ureteric substitution with Boari bladder flap. In 8 cases the ureteral stenting with DJ or a percutaneous nephrostomy was the solution., Results and Conclusions: In our experience good results can be obtained with ureteral implant and bladder psoas hitch. The end to end ureteral anastomosis had disappointing results in our hands. In case of ureteral fistula it would be better repair it as soon as possible. If the ureteral lesion is recognised during surgery and the loss of substance is not complete, the suture on stent can be performed.

From 1991 to 2001, 23 female patients were admitted to the Urologic Operative Unit of the Varese Hospital for urological lesions due to gynecological surgery. The mean age of the patients was 52 years. Out of them, 5 presented a complete division of the ureter after hysterectomy, 3 an inadvertently ligature of the ureter and 2 an angulation. In 12 cases a vesico-vaginal fistula was present, while a patient presented an uretero-vaginal fistula. The 5 patients with complete division of the ureter underwent: end-to-end anastomosis (3 patients); reimplantation (2 patients); psoas hitch (1 patient). In 3 patients with ureter ligation a reimplantation with psoas hitch was performed; in 2 cases with ureter angulation a double J stent was placed. The patient with an uretero-vaginal fistula underwent a reimplantation with psoas hitch while the patients with vesico-vaginal fistula were successfully treated by a combined transperitoneal and transvesical access, excision of the fistula tract and closure of the bladder and vaginal wall with omental interposition.

Objective: Ureteral lesions due to pelvic endometriosis, gynecological surgery and post-actinic are common findings in urology. Pelvic endometriosis can also be caused by a direct or indirect ureteral lesion after laparoscopic procedures. Stenosing ureteral lesions can be found after major gynecological surgery and after laparoscopic procedures. Many surgical techniques have been described to reduce the risks and to correct the complications., Materials and Methods: In our experience (1985-2000) we registered 2 ureteral lesions due to pelvic endometriosis. The patients were treated with resection and end-to-end anastomosis. We also protected the site of suture with omentoplasty. 49 patients developed a post-actinic ureteral lesion (43 unilaterally and 6 bilaterally). In 20 cases we performed an end-to-end anastomosis, in 25 cases we re-implanted the ureter and in 10 cases we performed a psoas hitch. In 36 patients we performed an omentoplastic procedure. Ureteral lesions after gynecological surgery were registered in 44 patients (33 after trans-vaginal hysterectomy, 6 after colposuspension, 5 after Wertheim). 40 ureters underwent open air surgery (26 patients, resection + end-to-end anastomosis, 6 patients simple re-implantation, 4 psoas hitch). In 32 patients we performed an omentoplastic procedure. 4 patients were corrected with an endoscopic procedure. These patients had a fulgurating lesion of the ureter with a consequent urinary fistula. A long-term drainage with endoureteral stent avoided the operation. All patients with an acute ureteral lesion were treated with a nephrostomic drainage and a short term repair., Results: In 2 patients with ureteral lesions due to pelvic endometriosis the results after corrective operation (3-4 years follow-up) were excellent with a good conservation of kidney function. In patients that underwent operation due to post-actinic ureteral stenosis, long-term results were: 78% complete preservation of kidney function without the need for permanent stents, 20% preservation of kidney function with need to conserve endoureteral stents, 2% loss of kidney function and consequent nephrectomy. Long-term results in patients that underwent an operation for ureteral lesions following surgical gynecological procedures were: 87% complete preservation of kidney function without the need of permanent stents, 13% conservation of kidney function but no need to preserve the endoureteral stent., Discussion: Lower urinary tract lesions after gynecological surgery are present in every surgical study. Most authors describe that intraoperative cystoscopy can immediately enhance the problem avoiding a re-operation. The laparoscopic risk seems to be for the cardinal ligaments when they divide beneath the uterine veins. Most authors seem to agree with the immediate need for a nephrostomic drainage followed by a postponed intervention. These procedures seem to reduce morbidity and the risk for a re-operation. In extended ureteral lesions there is agreement that psoas hitch is the best procedure. In our experience a nephrostomic drainage and a postponed intervention (2 weeks) has given comparable results with the best in literature as far as kidney function is concerned. The worst results were registered in patients with chronic lesions and with a deteriorated kidney function at the moment of the corrective procedure.

Background: At present, abdominoperineal resection remains the most diffuse method of treatment of very low rectal cancer. Today, we can avoid this method in some patients by using a sphincter-saving procedure., Methods: From March 1990 to January 1999, 273 consecutive total rectal resections and coloendoanal anastomoses were performed at our Institute; this study concerns 141 consecutive patients treated for a primary adenocarcinoma of the distal rectum, from 3.5 to 8 cm from the anal verge. Patient stratification, based on definitive pathological report, was 31 Dukes' stage A (T2N0), 44 stage B (T3N0), and 66 stage C (T2N+-T3N+)., Results: Overall recurrence rate was 9.2%; postoperative morbidity attributable to the procedure was low. A perfect continence was documented in 61% of cases. The only pathological factor related to local recurrence rate is peritumoral lymphocytic reaction inside and around the tumor (P = .0005 and .031) independently from the number of metastatic lymph nodes, depth of fatty tissue infiltration, and lymphatic and venous neoplastic emboli. The minimum follow-up time is 12 months., Conclusions: Our data, in accordance with other authors, seem to highlight the relevant role that a well-practiced surgery, together with accurate information on the spreading of this disease, has in achieving an optimal local control of cancer.

Causes of death were evaluated among 350 deceased patients with familial adenomatous polyposis (FAP) recorded in the Italian Polyposis Registry: 78.1% were due to colorectal cancer, 9.5% to extracolonic cancer (more than half of the upper gastrointestinal tract), 3.6% to desmoid tumors, and 8.8% to other causes. The age at diagnosis among 604 patients was studied in relation to presence of symptoms at presentation and presence of colonic cancer at surgery. In asymptomatic patients younger than 30 years the risk of colonic cancer was 3.3% and in symptomatic patients older than 40 it was 80%. A life-table analysis showed that postsurgical survival among patients without cancer at colectomy was 68% after 30 years, whereas that of patients with cancer was 41% after 10 years. The alternative prophylactic treatments of total colectomy with ileorectal anastomosis versus total proctocolectomy (IRA vs. IAA) were compared in terms of postsurgical survival. Both treatments showed a survival of 83% after 10 years. The risk of cancer in the rectal stump after IRA was 14.5% after 15 years and 25.2% after 25 years; the corresponding risks of dying from it were 4.3% and 9.3%, respectively.

The introduction of staplers in general surgery allowed to perform gastrointestinal anastomoses easier and with better results. Because many series report an important incidence of complications even using stapling instruments, the A.C.O.I. (Italian Association of General Hospital Surgeons), with the support of Auto Suture Italy, promoted a collaborative trial in Italy to evaluate the real incidence of complications after stapled colorectal or esophago-jejunal anastomoses. The study has been carried out during the period April 1990-December 1991 and 58 Centres throughout Italy participated with 420 esophagojejunostomies after Total Gastrectomy and 544 Colorectal anastomoses after Anterior Resection of the Rectum. Many variables were evaluated such as patients general conditions, the pathology and the site of anastomosis, the instrument used, the technique of reconstruction, if it was an urgent or an elective procedure, the incidence of intraoperative problems and the surgical experience. The most frequent complications were bleeding, leakage and stenosis. The incidence of bleeding was low in both groups, it was an occasional event not related with any of the variables previously described. Furthermore it was never important and never required reoperation or caused death of the patient. Leakage was the most frequent and serious complication (12.4% in colorectal anastomoses and 5.5% in esophagojejunostomies) and was mainly related to the incidence of intraoperative technical problems (tearing of the stump or purse string failure), to urgent procedures, to low and ultra low colorectal anastomoses and to centres with less experience, particularly with an experience of less than 50 mechanical anastomoses. Late complications such stenoses, were particularly frequent (8.4%) after a leakage and in very low colorectal anastomoses. Perioperative Mortality was very low in birth groups (1.1% for colorectal anastomoses and 2.6% for esophagojejunostomies) one of the lowest described in the Literature. This study seem to confirm that staplers are effective, safe and easy to use, showing a low incidence of complications and they make possible anastomoses otherwise technically impossible.

The changes occurred in the management of intestinal atresia in the last 30 years are presented. On the basis of a series of 55 neonates (29 M/26 F; 14 premature; mean body weight 2640 g, range 1340-4100 g; 23 duodenal, 30 small bowel, 2 colon) four aspects of this malformation are discussed; epidemiology, diagnostics, therapy and prognosis. Epidemiology. 40% incidence reduction is detected; unchanged the relative incidence of Down neonates with duodenal atresia. Diagnostics. Prenatal US scan useful in 4 of 8 cases only; emphasized the usefulness of plain X-ray abdomen. Perioperative treatment. Dramatic impact of the artificial nutrition on the management of short bowel syndrome, with 7 cases (residual small bowel from 75 to 9 cm, mean 40 cm) successfully treated. Surgical technique. Confirmed the validity of the one-stage termino-terminal anastomosis. Prognosis. Significant improvement in the last three decades respectively with 50%, 87% and 93% of long-term survivors. In the first decade 6 over 8 deaths were related to the atresia, while in the last 10 years the only death recorded was related to an associated severe cardiac malformation.
