A pancreas suture-less type II binding pancreaticogastrostomy / 中华外科杂志

<p><b>OBJECTIVE</b>To explore the feasibility and safety of type II binding pancreaticogastrostomy (BPG) in pancreaticoduodenectomy and mid-segmentectomy of pancreas.</p><p><b>METHODS</b>From November 2008 to May 2009, 26 patients underwent pancreaticoduodenectomy and mid-segmentectomy of pancreas with type II BPG reconstruction, including 13 cases of pancreatic head cancer, 3 cases of duodenal adenocarcinoma, 2 cases of ampullary carcinoma, 4 cases of cholangiocarcinoma, 1 case of bile duct cell severe atypical hyperplasia, and 1 case of stomach cancer. The process of type II BPG was described as the following: after pancreas remnant was mobilized for 2-3 cm, a piece of sero-muscular layer at the posterior gastric wall was excised and then a sero-muscular depth purse-suturing with 3-0 prolene was pre-placed (outer purse-string). Incising anterior gastric wall or opening part of the closed distal gastric stump, the mucosa layer at the sero-muscular defect was incised and then purse-suture at the mucosal tube was pre-placed (inner purse-string). Through the two pre-placed purse-strings, the pancreas remnant was pulled into the gastric lumen and then posterior gastric wall was pushed backward to keep it closely in contact with the retro-peritoneal wall. Thereafter, the outer purse-string was tied (outer binding) and then the inner purse-string was tied (inner binding).</p><p><b>RESULTS</b>All cases underwent BPG of type II. The operative time ranged from 3 to 5.5 hours. The postoperative hospital stay ranged from 6 to 48 days. Postoperative complications included 1 case of ascites, 2 cases of delayed gastric emptying and 1 case of intra-abdominal bleeding. All cases with complications were cured after nonsurgical treatment. No mortality or pancreatic leakage occurred.</p><p><b>CONCLUSIONS</b>Pancreaticogastrostomy is good for accommodating a large pancreas stump. Binding technique is very helpful in minimizing the leak rate of pancreaticogastrostomy. While type I BPG is safe and easy to perform, type II is even safer and easier to be done.</p>

Binding pancreaticogastrostomy / 中华外科杂志

<p><b>OBJECTIVE</b>To discuss the value of a new technique of the binding pancreaticogastrostomy (BPG) in pancreaticoduodenectomy.</p><p><b>METHODS</b>From May 2008 to October 2008, 15 patients were performed with BPG, included pancreatic head cancer in 7 cases, duodenal adenocarcinoma in 2 cases,mass-type chronic pancreatitis with pancreatolithiasis in 1 case, ampullary carcinoma in 1 case, gallbladder cancer in 1 case, islet cell tumor in 1 case and cholangiocarcinoma in 2 cases. The main procedures of BPG included: isolating remnant pancreas; slitting partial posterior wall of stomach and preplaced with seromuscular purse-string suture; cutting gastric anterior wall; performing pancreaticogastrostomy (binding of outer seromuscular and inner mucous layer of stomach).</p><p><b>RESULTS</b>The procedures were successful in 15 patients. Postoperative complications included small amount of pleural effusion in 2 cases, delayed gastric emptying in 2 cases and bile leakage in 2 cases. All patients were cured in 2 weeks. No mortality and anastomosis leakage occurred.</p><p><b>CONCLUSION</b>The application of BPG technique can prevent the anastomosis leakage and improve the safety for pancreaticoduodenectomy.</p>

A survey of bile duct injuries sustained during laparoscopic cholecystectomy / 中华外科杂志

<p><b>OBJECTIVE</b>To summarize the reasons for bile duct injury (BDI) after laparoscopic cholecystectomy (LC), and to determine the effect of multiple treatment after BDI.</p><p><b>METHODS</b>A retrospective cohort study was performed. The medical records of 110 patients diagnosed with BDI after LC from October 1993 to November 2007, in ten large hospitals in Guangdong of China, were reviewed.</p><p><b>RESULTS</b>Among 110 patients with BDI, 58 cases (52.7%) were local patients, whereas 52 cases (47.3%) were transferred from outside hospitals. Reasons for BDI following LC were: (1) Lack of experience of the LC operator (48.2%); (2) LC performed during acute cholecystitis (20.0%); (3) The structure of Calot triangle was unclear (15.5%); (4) Variable anatomical position (11.8%); (5) Intra-operation bleeding (4.5%). The commonest sites of injury were the choledochus and common hepatic duct (76.4%). Following BDI, endoscopic stenting or operative repair was performed in 106 patients. The overall success rate was 95.3% (101/106), with a mortality rate was 0.9% (1/106). Cholangitis occurred in 3.8% (4/106) cases. Choledocho-enterostomy operation was performed in almost 60.0% (63/106) cases, and the success rate was 93.7% (59/63). Endoscopic stenting or operative repair was performed immediately following BDI in 23.6% (25/106) patients, the success rate was 100%; and within 30 days in 63.2% (67/106) patients. Eighty-eight out of 106 patients who underwent repair were successful following the first operative procedure.</p><p><b>CONCLUSIONS</b>Factors such as an un-experienced operator and unclear anatomical position were causes of BDI following LC. Early operative repair should be regarded as the treatment of choice, in patients diagnosed with BDI. Early refer to an experienced hepatobiliary operator ensures a high success rate.</p>
