Safety and Efficacy of the Hand-Assisted Laparoscopic Approach for Repeat Hepatectomy: A Propensity Score Matching Analysis.

Background: Laparoscopic liver surgery following previous resections poses significant challenges due to adhesions and altered anatomy. Hand-assisted laparoscopic liver resection (HALR) combines the tactile advantages of open surgery with minimally invasive techniques, potentially benefitting patients undergoing repeat hepatectomy. This study aims to assess the safety and efficacy of HALR for repeat hepatectomy and compare these outcomes with those of an open liver resection (OR).
