Introduction: Minimally invasive major hepatic resection (MIMHR) is increasingly being performed in tertiary centers using either hand-assisted laparoscopic surgery (HALS) or totally laparoscopic surgery (TLS). The outcomes data of MIMHR are scarce, especially in comparison to open major hepatic resection (OMHR). Our aim was to compare 90-day outcomes in major hepatic resections when minimally invasive approaches are attempted. Methods and Procedures: At our institution, minimally invasive liver resection was formally introduced in January 2007, initially using the HALS approach. Since then, the use of TLS approach has increased. We collected data on all patients who underwent major liver resection between January 2007 and December 2017 at our institution. In an intention to treat fashion, we then compared MIMHR to OMHR. Results: From January 2007 to December 2017, 669 patients underwent liver resection. Of these, 203 patients (30%) underwent major hepatic resection and MIMHR and OMHR were performed in 68 (33%) and 135 (67%) patients, respectively. The rate of conversion from minimally invasive to open was 30.9%. Overall, there were no significant differences in 90-day mortality (2.9% versus 1.5%; P = .499) or major complications (14.7% versus 14.8%; P = .985). MIMHR was associated with a shorter average postoperative hospital stay (6.2 days versus 7.9 days; P = .0110) and shorter average ICU stay (0.66 days versus 0.90 days; P = .0299) compared with OMHR. Conclusions: The minimally invasive approach to major liver resection is a safe and reasonable alternative to an open approach when performed by a surgeon experienced with the relevant surgical techniques. MIMHR may be associated with similar outcomes and a shorter postoperative hospital stay with no increase in 90-day postoperative complications to OMHR.
