Abstract
OBJECTIVE: This study aimed to assess the safety and efficacy of left liver anatomical resection via the left vertical groove following intraoperative antegrade cholangioscopy (biliary exploration through the left hepatic duct orifice) in patients with left-sided hepatolithiasis (LSH) and previous biliary tract surgery. METHODS: Between January 2012 and January 2016, eligible patients with LSH (n = 28) who underwent left liver anatomical resection via the left vertical groove followed by intraoperative antegrade cholangioscopy, were referred to our hospital. Clinical results, such as the overall operative time, length of hospital stay, intraoperative complications, residual stones and postoperative bile leaks, were recorded and analyzed. RESULTS: No residual stones and bile leakage occurred in the patients. No patients experienced intraoperative complications or T-tube placement. The mean operative time was 135.1 ± 18.9 minutes. The mean postoperative duration of hospitalization was 7.8 ± 1.8 days. CONCLUSIONS: Left liver anatomical resection via the left vertical groove combined with intraoperative antegrade cholangioscopy is a safe and useful method for patients with LSH and previous biliary tract surgery. This technique simplifies the operative procedure by avoiding dissection of the porta hepatis and subsequent choledochotomy.
