Multicenter Study
Laparoscopic left liver resections: how far can we go?
Surgical Endoscopy 2017 December
INTRODUCTION: The aim of this study was to analyse the outcomes of laparoscopic anatomic hepatectomies of the left liver segments.
METHODS: This is a retrospective multicentre study including all patients operated on laparoscopically divided into unisegmentectomy of 2, 3 or 4 (Group 1), left lobectomy (or left lateral sectionectomy LLS) (Group 2), left hepatectomy (Group 3) and extended left hepatectomy (Group 4) between 2000 and 2016. These four groups were compared in terms of demographics, intraoperative data and postoperative outcomes.
RESULTS: Among the 190 selected patients, the groups 1, 2, 3, 4 included 25 (13.2%), 116 (61.0%), 27 (14.2%) and 22 (11.6%) patients, respectively. The cohorts were comparable except for the number of lesions (p = 0.001) and tumour diameter (p = 0.004). The operative time, blood loss and the use of vascular clamping were more frequent in the Groups 3 and 4 (p = 0.0001), as is the rate of conversion to laparotomy (p = 0.001). Total morbidity was 23.3%, and major complications were more frequent in Group 4 (p = 0.0001). The prevalence of hepatic complications (11.6%), intra-abdominal collections (7.4%) and respiratory complications (3.7%) was proportionally correlated to the hepatectomy extension (p = 0.0001).
CONCLUSION: All laparoscopic left liver resections seem safe and feasible even though extended hepatectomy is associated with a significant morbidity.
