Indocyanine green-assisted liver resection for colorectal liver metastases and factors associated with resection margin: a single-center retrospective study.

ABSTRACT:

Objective

This study aimed to compare the short-term outcomes of Indocyanine Green (ICG) assisted minimally invasive surgery (MIS) with Intraoperative Ultrasound (IOUS) against conventional MIS with IOUS alone and open surgery with tactility and IOUS for colorectal liver metastases (CRLM). And identify risk factor of R1 resection (tumor-negative margin < 1 mm) by statistical analysis.

Materials and methods

A retrospective cohort analysis was conducted on 86 patients with 158 CRLM tumors undergoing hepatectomy. Patients were categorized into three groups: Group A (ICG + IOUS MIS, n = 14, tumor = 23), Group B (IOUS only MIS, n = 16, tumor = 20), and Group C (tactile + IOUS Open surgery, n = 56, tumor = 115). Statistical analysis involved univariate analysis and multivariable l
