Short and long-term outcomes after minimally invasive liver resection for single small hepatocellular carcinoma: An analysis of 714 patients from the IGoMILS (Italian group of minimally invasive liver surgery) registry.

BACKGROUND Widespread use of minimally invasive liver surgery (MILS) contributed to the reduction of surgical risk of liver resection for hepatocellular carcinoma (HCC). Aim of this study was to analyze outcomes of MILS for single ≤3 cm HCC. METHODS Patients who underwent MILS for single ≤3 cm HCC (November 2014 - December 2019) were identified from the Italian Group of Minimally Invasive Liver Surgery (IGoMILS) Registry. RESULTS Of 714 patients included, 641 (93.0%) were Child-Pugh A; 65.7% were limited resections and 2.2% major resections, with a conversion rate of 5.2%. Ninety-day mortality rate was 0.3%. Overall morbidity rate was 22.4% (3.8% major complications). Mean postoperative stay was 5 days. Robotic resection showed longer operative time (p = 0.004) and a higher overall morbidity rate (p < 0.001), with similar major complications (p = 0.431). Child-Pugh B patients showed worse mortality (p = 0.017) and overall morbidity (p = 0.021), and longer postoperative stay (p = 0.005). Five-year overall survival was 79.5%; cirrhosis, satellite micronodules, and microvascular invasion were independently associated with survival. CONCLUSIONS MILS for ≤3 cm HCC was associated with low morbidity and mortality rates, showing high safety, and supporting the increasing indications for surgical resection in these patients.
