Modified method of hepatic portal choledochoplasty to treat benign strictures of hilar biliary ducts.
JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY(2008)
Abstract
Background and Aim: Roux-en-Y hepaticojejunostomy (RYHJ) is usually used to treat benign strictures of hilar bile ducts. However, RYHJ might also induce ascending cholangitis and recurrent hepatolithiasis. The present study aims to introduce a modified hepatic portal choledochoplasty with a pedicled graft of gallbladder (HPC) to treat this disease. Methods: One hundred and forty-nine patients, who had undergone HPC or RYHJ from January 1997 to January 2006 in our institutions, were included in this study, and the clinical data were retrospectively collected and analyzed. Results: The incidences of perioperative bile leakage and inflammatory ileus in patients treated with HPC were slightly lower than RYHJ without significant difference (1.89% vs 2.08% and 3.77% vs 5.21%, both P > 0.05). However, in a long-term follow up, patients treated with HPC had significantly lower incidences of cholangitis and recurrent hepatolithiasis (5.66% and 3.77%, respectively) than those treated with RYHJ (cholangitis, 21.88%; hepatolithiasis, 16.67%; both P < 0.05). Conclusion: Compared to RYHJ, HPC is a safer and more efficient method to treat benign strictures of hilar biliary ducts. It preserves the sphincter of Oddi and normal biliary duct pressure, thus avoiding bile reflux into the bile duct.
