OBJECTIVE: Laparoscopic hepatectomy is widely used in the surgical treatment of left-sided hepatolithiasis (LSH). Lithotomy using a cholangioscope usually is required for the treatment of concurrent right-sided hepatolithiasis or choledocholithiasis. The primary objective of this study was to evaluate the effectiveness and safety of gallstone elimination using cholangioscopy through the left hepatic duct (LHD) orifice versus the common bile duct (CBD). PATIENTS AND METHODS: Eligible LSH patients (n=41) were scheduled for laparoscopic left lateral segmentectomy or left hemihepatectomy with intraoperative biliary exploration using cholangioscopy through the LHD orifice (LHD group, n=23) or the CBD (CBD group, n=18) at the discretion of patients. Laparoscopic T-tube insertion was performed in selected patients. Patients were regularly followed up at monthly intervals or more frequently in the presence of any symptom. The primary outcome measures included overall operative time, duration of the cholangioscopy procedure, volume of blood loss, length of hospital stay, and frequency of procedure-related complications. RESULTS: The two groups were comparable in sex, age, symptoms, site of lesion, and gallstone comorbidities (P>.05). Of the 18 patients in the CBD group, 12 (66.7%) patients had a T-tube inserted in contrast to 1 (4.5%) patient in the LHD group. The two groups were comparable in cholangioscopy duration and volume of blood loss (P>.05), whereas the LHD group had a significantly shorter operative time than the CBD group (221.4 ± 58.6 minutes versus 171.2 ± 63.5 minutes; P<.05). The postoperative duration of hospitalization was significantly shorter in the LHD group than in the CBD group (7.5 ± 2.2 days versus 4.2 ± 1.9 days; P<.05). No patient showed any recurrence of gallstones or cholangitis during the follow-up period. CONCLUSIONS: As an effective and safe technique that is comparable to choledochotomy, LHD cholangioscopy is a preferred alternative to choledochotomy in the laparoscopic treatment of LSH because it offers patients shorter operative duration and length of hospitalization.
