[Initial experience of minimally invasive liver resection at a reference center in Mexico].

Objective: Minimally invasive liver resection is employed worldwide for the management of benign and malignant liver lesions. There is no description of postoperative outcomes in the Mexican population. This study aims to report the initial experience in Mexico.

Method: A cross-sectional analysis was performed on 20 patients undergoing minimally invasive liver resection between 2018 and 2024 at a reference center in Mexico. Quantitative variables are reported as mean ± standard deviation or median with range, while qualitative variables as frequencies with percentages.

Results: The most frequently performed procedures were left lateral sectionectomy in five cases, 7/20 were classified as intermediate and 10/20 as expert difficulty, according to the IWATE scoring criteria. Additional results included major complication (35%), intrahospital mortality (5%), surgical reintervention (0%), median hospital length of stay (6 [3-54] days) and R0 resection rate (76.9%).

Conclusions: The initial experience of minimally invasive liver resection in Mexico includes complex cases, with great difficulty according to the IWATE criteria, with comparable R0 resection rates.
