Minimally invasive complete mesocolic excision versus conventional right hemicolectomy for right-sided colon cancer: a systematic review and meta-analysis.

ABSTRACT:

Background and aims

There is insufficient evidence to support the application of complete mesocolic excision (CME) in minimally invasive surgery for right-sided colonic cancer. This meta-analysis was conducted to evaluate the efficacy and safety of minimally invasive CME compared with conventional right hemicolectomy for right-sided colonic cancer.

Methods

In adherence to PRISMA guidelines, 13 studies were included in the analysis (comprising 3 randomized controlled trials and 10 cohort studies, involving a total of 3,743 patients). Key outcomes assessed included lymph node yield, operative metrics, complication profiles, and survival outcomes.

Results

Minimally invasive CME demonstrated significantly higher lymph node retrieval (mean difference [MD]: 6.09, 95% CI: 3.
