Biliary exploration via the left hepatic duct orifice versus the common bile duct in left-sided hepatolithiasis patients with a history of biliary tract surgery: A randomized controlled trial.

Background: Hepatectomy and additional common bile duct exploration are required for the treatment of left-sided hepatolithiasis (LSH).
Methods: Eligible LSH patients (n = 62) scheduled for open left lateral segmentectomy or left hemihepatectomy with intraoperative biliary exploration via the left hepatic duct orifice (LHD group, n = 35) or the common bile duct (CBD group, n = 27) were retrospectively studied. T-tube insertion was performed on selected patients. Primary outcome measures included overall operative time, length of hospital stay, intraoperative complications, residual stones, and postoperative bile leaks.
Results: There were no residual stones observed in the 2 groups. Ten patients in the CBD group received T-tube placement, whereas no patients in the LHD group received T-tube placement. There were more patients in the CBD group suffered intraoperative complications and postoperative bile leakage than LHD group (P < .05). The LHD group had a significantly shorter operative time and hospitalization than the CBD group (P < .05).
Conclusion: For left-sided hepatolithiasis patients with a history of biliary tract surgery, LHD cholangioscopy is an accessible technique that simplifies the operation procedure by avoiding choledochotomy and subsequent T-tube insertion, which results in lower complication rates as well as shorter operative duration and length of hospitalization.
