Surgical management of benign strictures of the biliary tract.

Benign strictures of the biliary tract are difficult to treat surgical complications. Most biliary strictures result from injuries during cholecystectomies, and their initial management is a major determining factor of the long-term outcome. Only surgeons well trained and experienced in their management should treat this entity. The affected patients present various signs and symptoms depending on the time the lesion is detected, and the treatment modality largely depends on such timing. The success of surgical treatment with its attendant low morbidity and mortality makes it the preferred modality over transhepatic image-guided or endoscopic balloon dilatation, with or without the insertion of stents. Surgical treatment is based on three principles: good exposure for internal drainage of the intrahepatic biliary tract, mucosa-to-mucosa anastomosis, and prevention of the risk of reoperation for recurrent stenosis. Roux-en-Y hepaticojejunostomy with a blind subcutaneous jejunal loop seems to comply with these three principles. Transanastomotic stents are not necessary. We have analyzed our experience from 1988 to 1999 with 65 consecutive patients referred to us for biliary reconstruction. We used the Roux-en-Roux-en-Y hepaticojejunostomy with a blind subcutaneous jejunal loop, performed by the same surgical group in all cases.

Asymptomatic cholelithiasis revisited.

Elective cholecystectomy in the asymptomatic patient has elicited considerable controversy, going back to the prelaparoscopy cholecystectomy era. Surgical services often see patients with known or unidentified cholelithiasis who, having been asymptomatic, present with serious complications, potentially lethal, in whom emergency operations are associated with technical difficulties that lead to high conversion rates and significant mortality and morbidity. Elective cholecystectomy is a safe procedure associated with low morbidity and no mortality. Based on an analysis of our experience and a review of the literature, we discuss the indications for elective laparoscopic cholecystectomy in asymptomatic patients at high risk of developing complications of their asymptomatic disease. The following high-risk criteria are proposed for elective cholecystectomy: life expectancy > 20 years; calculi > 2 cm in diameter; calculi < 3 mm and a patent cystic duct; radiopaque calculi; polyps in the gallbladder (GB); nonfunctioning GB; calcified ("porcelain") GB; concomitant diabetes; women < 60 years; and individuals in geographic regions with a high prevalence of GB cancer.

Roux-en-Y hepaticojejunostomy with subcutaneous access and the use of Gianturco stents for the management of biliary tract strictures.

The need to control recurrent biliary strictures implies the practice of repeated major surgical procedures. The hepaticojejunostomy with subcutaneous jejunal access (Chen's procedure) allows the permanent option of a non-operative management of recurrent biliary tract anastomosis complications. Through the subcutaneous jejunal access, the application of a Gianturco metallic prosthesis is permitted and the correction of biliary-intestinal anastomosis strictures with non-operative methods is possible. This report is a review of a series of 20 patients treated with the Chen procedure, of whom 3 patients also had implantation of Gianturco stents via hepaticojejunostomy with subcutaneous access.
