Posterosuperior Segments of the Liver: Comparison of Short-Term Outcomes between Open and Minimally Invasive Surgery Performed by a Single Surgeon

Abstract

Laparoscopic posterosuperior liver segment resection is considered technically challenging. This is a retrospective single-center single-surgeon study. The aim of the present study is to investigate the short-term outcomes in a single institution between laparoscopic (LLR) and open (OLR) posterosuperior liver segments (PSSs) resections performed by a single surgeon at Parma University Hospital. The patients were divided into Group 1 (OLR) and Group 2 (LLR) and stratified in two different time settings according to the experience of the surgeon (2010–2015 and 2016–2021). A total 112 patients were included in the study. The 75.3% of OLR were performed in the first period, while 70.2% of LLR were carried out during the second period (2016–2021). The Iwate score was significantly (p p p > 0.05). The presence of liver cirrhosis and multiple lesions were identified as risk factors for severe postoperative complications. PSS-LLR has become much safer and more effective due to increasing surgeon’s expertise along with the implementation of cutting-edge technology and innovative surgical techniques.
