Abstract
Background This study aimed to investigate the safety and efficacy of laparoscopic anatomical left hemihepatectomy guided by the middle hepatic vein (MHV) for the treatment of patients with hepatolithiasis who had a history of upper abdominal surgery. Methods Retrospective data analysis was performed on patients who underwent laparoscopic left hepatectomy for hepatolithiasis and with previous upper abdominal surgery at the Second Affiliated Hospital of Nanchang University from January 2018 to April 2022. According to the different surgical approaches, patients were divided into laparoscopic anatomical left hepatectomy guided by the MHV group (MHV-AH group) and laparoscopic traditional anatomical left hepatectomy not guided by the MHV group (non-MHV-AH group). Results This study included 81 patients, with 37 and 44 patients in the MHV-AH and non-MHV-AH groups, respectively. There was no significant difference in the basic information between the two groups. Five cases were converted to laparotomy, and the remaining were successfully completed under laparoscopy. Compared to the non-MHV-AH group, the MHV-AH group had a slightly longer operation time (319.30 min vs 273.93 min, P = 0.032), lower bile leakage rate (5.4% vs 20.5%, P = 0.047), stone residual rate (2.7% vs 20.5%, P = 0.015), stone recurrence rate (5.4% vs 22.7%, P = 0.028), and cholangitis recurrence rate (2.7% vs 22.7%, P = 0.008).There were no significant differences in the results of other observation indices between the groups. Conclusions Laparoscopic anatomical left hepatectomy guided by the MHV is safe and effective in the treatment of left hepatolithiasis with a history of upper abdominal surgery. It does not increase intraoperative bleeding and reduces the risk of postoperative bile leakage, residual stones, stone recurrence, and cholangitis recurrence.
