Not all reoperative laparoscopic liver resection procedures are feasible for hepatolithiasis patients with a history of biliary surgery

¹χ² test was used.

²Kruskal-Wallis test was used.

³No χ² value was reported for Fisher's exact test.

⁴Two patients in the laparoscopic left hemihepatectomy subgroup had no postoperative imaging data and were excluded.

⁵Six patients in the reoperative laparoscopic left lateral sectionectomy subgroup, 11 in the reoperative laparoscopic left hemihepatectomy subgroup, and 3 in ther laparoscopic complex hepatectomy subgroup were excluded due to no follow-up data and residual stone.

⁶compared with the reoperative laparoscopic left lateral sectionectomy subgroup, P < 0.05.

⁷compared with the reoperative laparoscopic left hemihepatectomy subgroup, P < 0.05.

Data are presented as number/total number (percentage) of patients unless otherwise indicated. IQR: Interquartile range; ICC: Intrahepatic cholangiocarcinoma; N/A: Not applicable.
