BACKGROUND: Self-expandable metallic stent is an effective method in palliative treatment of malignant biliary stricture. However, it is controvesial in benign biliary stricture due to recurrent jaundice, cholangtitis, and finally, obstruction of stent. The purpose of this study was to determine the long-term effectiveness of Gianturco expandable metallic stents in benign biliary strictures. METHODS: We inserted Gianturco self-expandable metallic stent in 13 patients (42~69 years old, 6 men and 7 women) with benign biliary stricture between November 1991 and September 1994 in Wonkwang University Hospital. All patients had a previous history of biliary surgery and underwent balloon dilatation procedure for management of strictures. Insertion routes were percutaneous transhepatic biliary drainage tracks in 8 cases and T-tube tracks in 5 cases. The insertion site was the right intrahepatic duct in 5 cases, the left intrahepatic duct in 2 cases, both intrahepatic ducts in 1 case, common hepatic duct in 1 case, and distal common bile ducts in 4 cases. The stents used were 2~6cm in length and 8~12mm in diameter. The follow-up period was 46months to 81months(mean, 67months). RESULTS: The initial technical success rate was 100% with good immediate patency in all patients. Nine patients(69.2%) had no recurrence of the initial strictures during the follow-up period and 4 patients(30.7%) had further symptoms of biliary obstruction caused by recurrent cholangitis or intrahepatic duct stone formation. These 4 recurrent biliary strictures were treated by surgical methods. The recurrent stricture sites were distal common bile duct(1case), left intrahepatic duct(1case), both intrahepatic ducts(1case), and Roux-en-Y hepaticojejunostomy site(1case). CONCLUSIONS: According to the results of long-term follow-up, expandable metallic stent is a useful method in recurrent biliary strictures, especially in the case where operation is not feasible; poor risk patients, patients refusing operation, multiple biliary operation.

BACKGROUND: Recently, partial pancreatectomy has been performed for treatment of benign pancreatic lesion with special attention to functional preservation of adjacent organs. In contrast to traditional pancreaticoduodenectomy( Whipple's procedure) and pylorus-preserving pancreaticoduodenectomy(PPPD), the duodenum-preserving pancreatic head resection(DPPHR) preserves stomach, duodenum, jejunum, extrahepatic bile duct, and this procedure is reported to preserve function of adjacent organs, to reduce morbidity and mortality rates. The indications of DPPHR are benign lesion of the head of the pancreas as well as complications of chronic pancreatitis, including distal common bile duct obstruction, duodenal obstruction, colonic stenosis, pseudocyst of the head of the pancreas, internal pancreatic fistula, portal or splenic vein stenosis. Also this procedure is indicated for the management of the pancreatic head injury. Reconstructive methods following resection of the pancreatic head are modified variously, this methods are end-to-end anastomosis of the pancreatic duct, Roux-en-Y pancreaticojejunostomy, pancreaticogastrostomy, pancreaticoduodenostomy. MATERIALS AND METHODS: The authors performed DPPHR in 4 patients; pseudocyst of the pancreatic head 1, pancreatic head injury 2, chronic pancreatitis 1. Two patients with pseudocyst of the pancreatic head and pancreatic head injury underwent end-to-end anastomosis of the pancreatic duct after resection of the head of the pancreas. This procedure involved insertion of feeding tube into the pancreatic duct and then end-to-end anastomosis of the pancreatic duct. Other two patients with pancreatic head injury and chronic pancreatitis underwent Roux-en-Y pancreaticojejunostomy after resection of the head of the pancreas. RESULTS: Two patients with end-to-end anastomosis of the pancreatic duct developed leakage of the anastomotic site of the pancreatic duct at 3rd and 8th postoperative days, respectively. So this patients were performed reoperation, Roux-en-Y pancreaticojejunostomy. But the peripancreatic abscess developed after reoperation and then performed drainage of the abscess. This patients were improved and discharged. Total hospital stay was 35days and 34days, respectively. Other two patients underwent Roux-en-Y pancreaticojejunostomy after resection of the head of the pancreas. This patients were improved without complications and discharged within 1 month. CONCLUSIONS: In our experiences, DPPHR can be appropriated in the treatment of complications of chronic pancreatitis, benign lesion of the head of the pancreas, pancreatic head injury. And we consider that the Roux-en-Y pancreaticojejunostomy is more safe reconstructive method, compare with the end-to-end anastomosis of the pancreatic duct.

The pancreatic pseudocyst as a sequela of pancreatitis or pancreatic trauma can occur at any site in the abdomen. Its detection seems to be increasing with modern imaging tools such as abdominal ultrasound or abdominal CT scanning. But recently, we experienced a case of a pseudocyst due to a ruptured pancreatic pseudocyst which was misdiagnosed as a simple hepatic cyst by abdominal ultrasonography or abdominal CT scan. A 12-year-old male presented with recurrent epigastric pain during the past 4 years. On the abdominal ultrasound and abdominal CT scan, there was an 8x7.5 cm sized sharply defined thin-walled cyst in the left lobe of the liver. First, percutaneous (cather) drainage guided by ultrasonography was done. An exploratory laparotomy was performed because of signs of hemoperitoneum. A 8x7.5 cm sized cyst was found at the left subhepatic space, which communicated with another smaller cystic lesion in the pancreatic head. Microscopic finding of the cyst showed infiltration of inflammatory cells and granulation tissue without ephithelial lined cells which is compatible to a pseudocyst. So we report this case with a review of literatures.
