Methods A prospective controlled trial was conducted with 165 cases receiving pancreati- coduodenectomy in the Department of Hepatopancreatobiliary Surgery from January 2010 to May 2012. The patients were divided into Group A （end-to-end/end-to-side invaginated anastomosis, n=52）, Group B （end-to-side mucosal anastomosis, n=48）, and Group C （SPDJCS, n=65）. The preoperative data, intra- operative data, and operative outcomes （incidence of pancreatic fistula, operation time, intraoperative blood loss, peritoneal drainage, peritoneal hemorrhage, peritoneal abscess, delayed gastric emptying, pulmonary infection, postoperative infection, blood transfusion, and perioperative mortality） were com- pared among the 3 groups. Results The total incidence of pancreatic fistula was 13.9% （23/165） in all the 165 patients. The inci- dence in Group A and Group B was 23.1% （12/52） and 18.8% （9/48）, both higher than that in Group C [3.1% （2/65）, both P〈0.05]. Group C showed significantly better outcomes than group A and B in terms of the opera- tion time （5.5±1.2 hours vs. 6.1±1.1 hours, 5.5±1.2 hours vs. 6.3±1.5 hours）, volume of blood loss （412.0±205.0 mL vs. 525.0±217.0 mL, 412.0±205.0 mL vs. 514.0±217.0 mL）, and postoperative drainage amount of plasma tubes （175.0±65.0 mE vs. 275.0±80.0 mL, 175.0±65.0 mL vs. 255.0±75.0 mL） （all P〈0.05）, while Group A and Group B displayed no difference in these aspects （P〉0.05）. As complications other than pancreatic fistula were concerned, the three groups were not different from each other （P〉0.05）. Conclusions SPDJCS may have the effect of reducing the incidence of pancreatic fistula after pan- creaticoduodenectomy. It could be safe, practical and convenient technique of anastomosis for pancreaticoje- junostomy.展开更多

METHODS： Seventeen consecutive patients with paraampullar malignancy received polyprolene meshreinforced pancreatodudeonectomy and the Child＇s method was used to rebuild the alimentary tract. RESULTS： The mean time of polyprolene mesh-reinforced pancreatojejunostomy was 22 rain. Anastomosis could endure 30-500 cm H20 pressure during operation. All patients recovered without pancreatic leakage. CONCLUSION： Polyprolene mesh-reinforced pancreatojejunostomy is a feasible and reliable procedure to prevent pancreatic leakage.展开更多

Pancreatic fistula occurred in 14 patients （11%） among the interrupted suture cases and in 10 （6%） among the continuous suture cases （P = 0.102）. Major pancreatic leakage developed in three interrupted suture patients （2%） and zero continuous suture patients （P = 0.026）. In multivariate analysis, soft pancreatic consistency （odds ratio, 5.5; 95% confidence interval 2.3-13.1） and common bile duct cancer （odds ratio, 3.7; 95%CI 1.6-8.5） were＇predictive of pancreatic leakage.CONCLUSION： Pancreatic texture and pathology are the most important factors in determining the fate of pancreaticojejunal anastomosis and our continuous suture method was performed with significantly decreased occurrence of major pancreatic fistula. In conclusion, the continuous suture method is more feasible and safer in performing duct-to-mucosa pancreaticojejunostomy.展开更多

We describe a 62-year-old man with jejunal ectopic pancreas that led to jejunojejunal intussusception and ileus. The patient was admitted to our hospital because of intermittent abdominal pain. Plain abdominal radiography showed some intestinal gas and fluid levels. Abdominal CT scan demonstrated a target sign suggesting bowel intussusception. Jejunography using a naso-jejunal tube showed an oval-shaped mass about 15 mm in diameter with a smooth surface in the jejunum, which suggested a submucosal tumor (SMT), and edematous mucosa around the mass. Partial jejunal resection was carried out and the resected oval-shaped tumor, 14 mm×11 mm in size, was found to be covered with normal jejunal mucosa. The tumor was histologically diagnosed as type ectopic pancreas according to the classification proposed by Heinrich.Abdominal pain resolved postoperatively.This case reminds us that jejunal ectopic pancreas should be included in the differential diagnosis of intussusception caused by an SMT in the intestine.展开更多
