Restoration of good portal blood flow is essential for recovery in the early postoperative period and for long-term survival. However, such extended resections often result in large defects at the bifurcation of the portal vein that are not amenable to suturing or end-to-end anastomosis. A patch graft technique is very useful for reconstruction of long and elongated defects when other methods are not technically appropriate. We describe a simple technique for reconstructing the portal vein using a patch graft obtained from the hepatic vein stump of the resected specimen. This technique permits surgeons to reconstruct the portal vein without any need for harvesting another vein and with no need for an additional incision.

Summary Background Data: Although LT provides longer survival than liver resection for treatment of small HCCs, donor shortage and long LT wait time may argue against LT. The feasibility and survival following LT after hepatic resection have not been previously examined. Methods: Between 1991 and 2001, among 107 patients who underwent LT for HCC, 88 met Mazzafero's criteria upon pathologic analysis of the explant. Of these, 70 underwent primary liver transplantation (PLT) and 18 liver resection prior to secondary liver transplantation (SLT) for recurrence (n ϭ 11), deterioration of liver function (n ϭ 4), or high risk for recurrence (n ϭ 3). Perioperative and postoperative factors and long-term survival were compared. Results: Comparison of PLT and SLT groups at the time of LT revealed similar median age (53 vs. 55 years), sex, and etiology of liver disease (alcohol/viral B/C/other). In the SLT group, the mean time between liver resection and listing for LT was 20 months (range 1-84 months). Overall time on LT waiting list of the two groups was similar (3 vs. 5 months). Pathologic analysis after LT revealed similar tumor size (2.2 vs. 2.3 cm) and number (1.6 vs. 1.7). Perioperative and postoperative courses were not different in terms of operative time (551 vs. 530 minutes), blood loss (1191 vs. 1282 mL), transfusion (3 vs. 2 units), ICU (9 vs. 10 days) or hospital stay (32 vs. 31 days), morbidity (51% vs. 56%) or 30-day mortality (5.7% vs. 5.6%). During a median follow-up of 32 months (3 to 158 months), 3 patients recurred after PLT and one after SLT. After transplantation, 3-and 5-year overall survivals were not different between groups (82 vs. 82% and 59 vs. 61%). Conclusions: In selected patients, liver resection prior to transplantation does not increase the morbidity or impair long-term survival following LT. Therefore, liver resection prior to transplantation can be integrated in the treatment strategy for HCC. (Ann Surg 2003;238: 885-893) From the

They are usually mistaken for sciatic hernia, rectal prolapse or other diseases in the perineum. Correct identification of the type of hernia by imaging is crucial for planning treatment. We present a case of primary posterior herniation of urinary bladder and rectal wall through levator ani repaired laparoscopically using a mesh repair.

This study aims at a retrospective analysis of operative and short term outcome of patients with rectosigmoid tumours. A retrospective analysis of operative, postoperative and short-term outcome of 62 patients who underwent laparoscopic colorectal resection for cancer of rectosigmoid region were compared with a same number of parameters-matched patients who underwent open colorectal resection. Blood transfusion requirement was significantly more in the open group compared to the laparoscopy group (38.7% versus 6.4%, p=0.001). ICU stay was less in the laparoscopy group (p=<0.05) and they were started on oral liquid diet earlier (p=0.013). The number of the lymph nodes retrieved, positive distal margin and radial involvement were similar in both groups. The hospital stay was significantly shorter in laparoscopy group (8.4 versus 13.8 days, p < 0.05). Radical operation for rectosigmoid tumors is technically feasible with laparoscopic surgery. Laparoscopic approach is associated with less blood loss, transfusion and significantly less ICU stay. Laparoscopic group recovers early and needs less hospital stay

This article describes the clinical features of eight patients who presented with biopsyproven tuberculosis at the port-site unassociated with other clinical features of tuberculosis. Three of the eight patients had positive cultures for Mycobacterium tuberculosis. The port-site sinuses healed with antituberculous chemotherapy. There is conflicting information in the literature regarding the effectiveness of a 20-min instrument soak in 2% glutaraldehyde to clear M. tuberculosis. In light of the preceding information, the current practice of glutaraldehyde disinfection for reusable laparoscopes needs to be reexamined.

However, it is widely believed that as the experience of the surgeon/unit improves the results get better. This study aims to assess the pattern of case selection and short-term results of laparoscopic colorectal surgery in a high volume centre in two different time frames. This study was done from the prospective data of 265 elective laparoscopic colorectal resections performed in a single unit from December 2005 to April 2011. The group was subdivided into initial 132 patients (Group 1) from December 2005 to December 2008 and next 133 patients (Group 2) between December 2008 and April 2011 who underwent laparoscopic colorectal resections for cancer. The groups were compared for intraoperative and perioperative parameters, type of surgery, and the stage of the disease. The age of patients was similar in Groups 1 and 2 (57.7 and 56.9, respectively). Patients with co-morbid illness were significantly more in Group 2 than in Group 1 (63.2% vs. 32.5%, respectively, P≤0.001). There were significantly more cases of right colonic cancers in Group 1 than in Group 2 (21.9% vs. 11.3%, respectively, P&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.02) and less number of low rectal lesions (20.4% vs. 33.8%, respectively, P≤0.02). The conversion rates were 3.7% and 2.2% in Groups 1 and 2, respectively. The operating time and blood loss were significantly more in Group 1 than in Group 2. The ICU stay was significantly different in Groups 1 and 2 (31.2± 19.1 vs. 24.7± 18.7 h, P≤0.005). The time for removal of the nasogastric tube was significantly earlier (P=0.005) in Group 2 compared to Group 1 (1.37± 1.1 vs. 2.63±1.01 days). The time to pass first flatus, resumption of oral liquids, semisolid diet, and complications were similar in both groups. The hospital stay was more in Group 1 than in Group 2 ( P≤0.01). The numbers of lymph nodes retrieved was similar in both groups. The T stage of the disease in Groups 1 and 2 were similar, however, the number of T4 lesions was significantly more in Group 2 (8.3% vs. 18.7%, respectively, P&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.01). This study shows that with increasing experience, laparoscopic colorectal surgery can be practiced safely with minimal conversion rates and morbidity. As the units experience improves, there is a trend towards selecting advanced cases and performing complex laparoscopic colorectal procedures. With increasing experience, there is a trend towards better short-term outcome after laparoscopic colorectal surgeries.

The presence of retroperitoneal air is a sign of anaerobic sepsis. A retrospective review of case records of patients presenting with severe acute pancreatitis and pancreatic necrosis was performed to identify cases in whom conservative treatment was followed by a satisfactory outcome. Four patients were identified over a 3-year period who had pancreatic necrosis and retroperitoneal air; they were treated with antibiotics and intensive care, and they improved without any interventional treatment. Some patients with infected pancreatic necrosis are treatable medically. The clinical status of the patients may well be a more important factor governing the choice of the treatment approach than bacteriological findings of infection alone.

Patients with intrahepatic calculi require multiple interventions following successful surgical s... more Patients with intrahepatic calculi require multiple interventions following successful surgical stone clearance for recurrent stones and cholangitis. The present paper describes the results of a technique of in-continuity side-to-side jejunoduodenal anastomosis (JDA) that provides endoscopic access to the hepaticojejunostomy and intrahepatic ducts. This operation is compared to other techniques in a critical appraisal of various biliary access procedures described for long-term management of intrahepatic -calculi. A retrospective analysis of clinical data of 13 patients who underwent biliary drainage procedures with access loops for intrahepatic calculi during the period March 1990 to December 2000 was performed. The postoperative course of patients and the feasibility of postoperative endoscopic access to the hepaticojejunostomy and intrahepatic ductal system in treatment of recurrent cholangitis were assessed. Nine patients underwent JDA, two underwent permanent-access hepaticojejunostomy (PAH) and two others underwent an interposition hepaticojejunoduodenostomy (IHJ). The analysis revealed no major procedure-related complications or mortality. Endoscopic access (using forward-viewing gastroscope) was possible in 100% of cases following JDA, and with difficulty in both cases after PAH. Endoscopic access in the two patients with IHJ failed because of technical reasons. Recurrent cholangitis was seen in seven patients (54%) - two out of two patients in the PAH group, one out of two in the IHJ group and four out of nine in the JDA group. This required 12 endotherapy sessions (mean: 1.5 procedures per patient). In-continuity side-to-side JDA allows easy access of conventional gastroduodenoscopes to the biliary tree for removal of recurrent/residual intrahepatic stones. The technique has advantages over other access loop procedures in the long term management of recurrent intrahepatic stones.

Pancreatic ascites or internal pancreatic fistula is a known complication of chronic pancreatitis... more Pancreatic ascites or internal pancreatic fistula is a known complication of chronic pancreatitis. This condition is associated with considerable morbidity and mortality. The management approach of pancreatic ascites in tropical calcific pancreatitis is infrequently reported owing to the low incidence of this condition. Between December 2005 and June 2007, 11 patients with pancreatic ascites with tropical calcific pancreatitis (male:female 7:4, mean age 29.5 [14.2] years) were treated. A retrospective analysis of patients who underwent endotherapy and surgery for this condition based on an institutional protocol was performed. The end point was resolution of pancreatic ascites and relief of symptoms. All patients had pancreatic ascites, and one patient also had pancreatic pleural effusion. Endoscopic transpapillary stenting was possible in nine patients (81 ). Identification of site of leak and placement of an endoscopic stent across the PD disruption was possible in five (45 ) patients. All these patients had relief of ascites. Mean number of endotherapy sessions required before control of ascites was 1.8. Among the remaining four (36.6 ) patients who had ERCP, placement of stent across the leak was unsuccessful; however stenting helped stabilize the general condition and nutritional status. These four patients and two patients who failed ERP underwent lateral pancreatojejunostomy surgery. Morbidity was observed in three patients who underwent surgery and one patient died due to sepsis and hemorrhage. All patients who had surgical drainage had complete relief of ascites and symptoms. In patients with pancreatic ascites in tropical calcific pancreatitis endotherapy and transpapillary stenting helps in resolution of ascites in nearly half of the patients. In the remaining patients preliminary conservative management followed by surgical pancreatic ductal drainage provides good relief of symptoms.
