Outcomes of high BMI colorectal cancer patients with natural orifice specimen extraction surgery: a propensity-score matching study.

ABSTRACT:

Background

Natural orifice specimen extraction surgery (NOSES) is widely used for colorectal cancer. However, there is limited study regarding the outcomes of patients with high BMI who undergo NOSES surgery for colorectal cancer.

Methods

This retrospective study included 251 patients (including 205 Non-High BMI and 46 High BMI patients) who underwent NOSES for colorectal cancer between January 2013 and December 2018. Outcomes related to surgery, anal function and long-term survisval were compared between the Non-High BMI and High BMI patients with the propensity-score matching (PSM) method. Age, gender, tumor location (sigmoid/rectum), preoperative CEA, CA199, T stage and N stage were considered as covariates for PSM.

Results

After matching, 44 patients in the Non-Hi
