Methods Binding pancreaticojejunostomy was perfomed in 100 patients from 1996 to 2000.During the operation,the cut end of the je-junum(3 cm) was everted,the everted mucosa of the jejunum was destroyed with carbolic acid .Meanwhile 3 cm long remnant of pancreas was isolated and sutured to 3 cm away form the jejunum cut end, care being taken not to penetrate the sero-muscular layer.Then,the everted jejunum was restituted to its nomal position and the remnant of the pancreas was naturally pushed into the jejunal lumen for 3 cm.Finally,the surface of pancreatic remnant was closely in contact with destroyed jejunal mucosa surface,and a piece of absorbable thread was used to bind circumferentially this jejunum and the pancreatic remnant together,so no gap existed between the jejunal mucosa and pancreatic remnant. Results No pancreatic leakage occurred in the 100 patients with BPJ. Conclusion Binding pancreaticojejunostomy procedure can effectively prevent the occurrence of anastomatic leakage and can be applied broadly.展开更多

Methods: From 1994 to 2002, 15 patients with HCC and BDT who underwent surgical intervention were retrospectively analyzed.Results: The operative procedures included hepatectomy with removel of BDT (n=7), hepatectomy com-bined with extrahepatic bile duct resection (n=4), thrombectomy through choledochotomy (n=3), piggy back orthotopic liver transplantation (n=1). The 1-and 3-year survival rates were 73.3% and 40%, respec-tively. Two patients survived over 5 years. Conclusion: Surgical intervention was effective for patients with HCC and BDT. Operation for recurrent lesion can prolong survival period. Liver transplantation is a new treatment worthy of further investigation.展开更多
