Surgical treatment for bile duct stone with absence of hepatic duct abnormality

Objective To evaluate the clinical significance of bile duct stone with bile duct abnormality and improve the surgical technique and diagnostic ability for this situation.Methods We retrospectively analyzed the diagnostic and treatment data of 5 cases of bile duct stone with absence of hepatic duct abnormality during the past one year.Results All 5 cases of abnormality were confirmed during surgical exploration. For these abnormalities, 4 cases were absent of right hepatic duct and 1 case was absent of left hepatic duct. Stone extraction with liver resection and hepatojejunostomy were carried out for this group of patients. The results were good and there were no reports of residual stones or surgical complications.Conclusion Bile duct abnormality should be noticed during surgery exploration for hepatic stones. Resection of lithogenic and anatomically abnormal liver lobe is required for a successful operation in this situation.
