Efficacy of Laparoscopic Left Hemihepatectomy Combined With Choledochoscopic Lithotomy for Complex Intrahepatic Bile Duct Stones and Its Impact on Postoperative Liver Function.

Background: This study was designed to investigate the clinical efficacy of laparoscopic left hemihepatectomy combined with choledochoscopic lithotomy for patients with complex intrahepatic bile duct stones.

Materials and methods: The clinical data of 97 patients with complex intrahepatic bile duct stones treated in our hospital between February 2019 and April 2022 were retrospectively collected. Patients were allocated into 2 groups based on their surgical approaches. In the control group, 46 patients underwent laparoscopic left hemihepatectomy, while in the combined group, 51 patients underwent laparoscopic left hemihepatectomy combined with choledochoscopic lithotomy. Parameters such as clinical efficacy, surgical indices, stress response markers (CRP, EP, COR), coagulation metrics (FIB, APTT, PT), liver function indicators (GGT, TBIL, ALT), complications, and quality of life were compared between the 2 groups.

Results: The combined group exhibited a significantly higher total effective rate compared with the control group (98.04% vs. 82.61%) (P<0.05). The operation duration of the combined group was longer than that of the control group. However, the duration for postoperative anal exhaustion, postoperative bed mobility, postoperative drainage, and hospital stay was shorter in the combined group than in the control group (P<0.05). CRP, EP, and COR concentrations were substantially elevated in both groups on the third postoperative day (P<0.05), but were lower in the combined group. Similarly, levels of FIB, APTT, and PT were markedly increased in both groups on the third postoperative day (P<0.05), but were lower in the combined group. On the seventh postoperative day, GGT, TBIL, and ALT were notably decreased in both groups, with the combined group exhibiting lower levels (P<0.05). The incidence of complications in the combined group was lower than that of the control group (5.88% vs. 19.57%) (P<0.05). At 3 months postoperatively, all GIQLI scores were markedly elevated in both groups, with superior scores observed in the combined group (P<0.05).

Conclusion: The combined laparoscopy and choledochoscopy demonstrate a remarkable efficacy for complex intrahepatic bile duct stones, which significantly facilitate liver function recuperation, reduce stress reactions, reduce complications, enhance the quality of life, and exert a minimal impact on coagulation functions.
