Laparoscopic Liver Resection: A South American Experience with 2887 Cases

Abstract

Background Laparoscopic liver resections (LLR) have been increasingly performed in recent years. Most of the available evidence, however, comes from specialized centers in Asia, Europe and USA. Data from South America are limited and based on single‐center experiences. To date, no multicenter studies evaluated the results of LLR in South America. The aim of this study was to evaluate the experience and results with LLR in South American centers. Methods From February to November 2019, a survey about LLR was conducted in 61 hepatobiliary centers in South America, composed by 20 questions concerning demographic characteristics, surgical data, and perioperative results. Results Fifty‐one (83.6%) centers from seven different countries answered the survey. A total of 2887 LLR were performed, as follows: Argentina (928), Brazil (1326), Chile (322), Colombia (210), Paraguay (9), Peru (75), and Uruguay (8). The first program began in 1997; however, the majority (60.7%) started after 2010. The percentage of LLR over open resections was 28.4% (4.4–84%). Of the total, 76.5% were minor hepatectomies and 23.5% major, including 266 right hepatectomies and 343 left hepatectomies. The conversion rate was 9.7%, overall morbidity 13%, and mortality 0.7%. Conclusions This is the largest study assessing the dissemination and results of LLR in South America. It showed an increasing number of centers performing LLR with the promising perioperative results, aligned with other worldwide excellence centers.

Early adoption of laparoscopic liver surgery in Poland: a national retrospective cohort study

“…Rates of LLR in relation to the total number of liver resections ranged from 3.9 to 14.8% 20 , 21 , 36 . With the next decade, national LLR rates almost doubled, reaching even 24.8% in the biggest national cohort from Japan 19 , 37 , 38 . While analyzing more selected cohorts and differentiating centers in accordance to the number of cases performed per year, there are studies which presents up to 42.9% rate in high volume centers 39 .…”
