Abstract

Laparoscopic cholecystectomy is the standard of care for cholecystolithiasis but carries an increased risk of biliary injury compared to open cholecystectomy. Complications from laparoscopic cholecystectomy can be related to several factors. These include - (i) technical factors that depend on the skill of the surgeon, (ii) pathologic factors such as associated inflammation and adhesions, and (iii) anatomic factors such as biliary anatomy. Aberrant biliary anatomy is a major cause of bile duct injury during surgery. To the best of our knowledge familial aberrant biliary anatomy has not been previously reported in the literature. We report a case series of two biological sisters with isolated posterior right duct syndrome and present a brief literature review of this medical condition.

Keywords: aberrant; bile; duct; familial; posterior; right.
