Safety and feasibility of laparoscopic left hepatectomy for the treatment of hepatolithiasis in patients with previous abdominal surgery.

Background The aim of the study was to compare the benefits and drawbacks of laparoscopic left hepatectomy (LLH) in patients with previous abdominal surgery (PAS) with those in patients without PAS and confirm the safety and feasibility of LLH as a treatment for patients with hepatolithiasis and PAS. Materials and methods This retrospective comparative study included 111 patients who underwent LLH for hepatolithiasis (with PAS, n = 41; without PAS, n = 70) from August 2017 to August 2019. Patients' general information, surgical outcomes, hospital stay duration, hospitalisation cost, post-operative laboratory data and post-operative complications were evaluated. Results No statistically significant difference was noted in the post-operative laboratory data between patients with and without PAS (P > 0.05). Longer operative times were required for patients with PAS than for those without PAS (P = 0.025). Hospitalisation cost, hospital stay duration, blood loss, open conversion and post-operative complications were not significantly different between patients with and without PAS (P > 0.05). No cases of mortality were noted. Conclusions LLH is a safe and feasible treatment for patients with hepatolithiasis and PAS.
