Abstract
BACKGROUND: Laparoscopic hepatectomy (LH) is technical challenge for patients with previous upper abdominal surgery (UAS), especially for those with previous liver resection. The purpose of this meta-analysis is to assess the safety and feasibility of laparoscopic liver resection for patients with previous UAS, in comparison with primary laparoscopic liver resection which means patients without previous upper abdominal surgery (non-UAS). METHODS: All case-matched articles published from date of inception to 15th April 2018 were identified independently by two reviewers. Perioperative outcomes were analyzed. Data were extracted and calculated by random- or fixed-effect models. In addition, subgroup analysis according to patients with history of liver resection was performed. RESULTS: A total of 8 non-randomized observational articles were included, with 1625 patients (430 patients in UAS group and 1195 in non-UAS group). The results showed that there was no significant difference between the two groups in perioperative outcomes. In the subgroup analysis of patients with a history of liver resection, however, LH for patients with previous liver resection had longer operative time comparing with patients without previous liver resection (WMD = 33.03, 95% CI 3.16 to 62.90, P = 0.030); other perioperative outcomes were similar between UAS and non-UAS groups. CONCLUSION: LH is feasible and safe for selected patients with previous UAS comparing with that of primary resection, although LH has longer operative time for patients with previous liver resection.
