A Modified Perfusion Method to Improve the Quality of Procured Donor Pancreas in Rats.

Background: In this animal study, we evaluated a modified pancreas perfusion method to improve the quality of harvested pancreas in rats. In this model, the portal vein was used as the outflow route during the pancreas perfusion.

Methods: Forty-eight male Wistar rats were randomly divided into study group and control group, with 24 rats in each group.

Invaginated Pancreaticojejunostomy via the Space Behind the Root of Superior Mesenteric Vessels.

Background: This study was to explore a safe and effective procedure to prevent pancreatic fistula (PF) after pancreaticoduodenectomy (PD).

Methods: Forty-three modified PD with pancreaticojejunostomy by direct invagination of the pancreas to the jejunum that was brought up via the space behind the root of superior mesenteric vessel were performed between January 2003 and June 2006, and were compared to the fifty-six conventional PD (Child' method).

Results: There was no pancreatic fistula after PD in the modified group.

A Novel Approach with Supra- and Retro-hepatic Cavocaval Bypass for Short Segmental Occlusion of Inferior Vena Cava in Budd-Chiari Syndrome.

Background: Budd-Chiari syndrome (BCS) is defined as chronic, progressive and congestive liver dysfunction resulting from obstruction of the outflow of inferior vena cava (IVC) and/or hepatic veins. One of the common types of BCS is short segmental occlusion of retrohepatic IVC (SSOR-IVC) accompanied by varied extent of obstruction of intrahepatic veins. The mainstay of surgical treatment at present for SSOR-IVC is cavoartrial bypass via thoracolaparotomic approach, in which thoracic and pulmonary complications intra- and/or post-operation are common.

Extended local resection for treatment of periampullary carcinoma of vater.

Background: The trauma caused by pancreatoduodenectomy for periampullary carcinoma of vater is often severe and extensive. The purpose of this study was to evaluate the effect of extended local resection in the treatment of periampullary carcinoma of vater.

Methods: The extra-hepaticobiliary tract, the confluence of the pancreatic and biliary duct, vater ampulla and duodenal papilla were resected en bloc in 8 patients with periampullary carcinoma from 1995 to 1998.

Surgical treatment for uncinate process carcinoma of the pancreas.

Objectives: To analyze the clinical features of uncinate process carcinoma of the pancreas and to improve the resection rate.

Methods: From January 1990 to June 1999, 10 patients with pancreas uncinate process carcinoma received Whipple's operation. Portal vein (PV) resection and reanastomosis were performed in 5 patients, and the resected length varied from 2.
