| Summary: | Objectives: Stomal prolapse (SP) is one of the most common complications of loop colostomy and can impair a patient's quality of life. Herein, we evaluated the risk factors for SP to prevent its occurrence after a transverse loop colostomy.
Methods: This retrospective study included 84 patients who underwent loop transverse colostomy between January 2016 and December 2020. We evaluated the incidence of SP and examined the relationship between perioperative factors and SP using univariate and multivariate logistic regressions.
Results: SP occurred in 11 (13.0%) patients. Median time to SP was 99 postoperative days. In the univariate analysis, a right side abdominal wall stoma site, perioperative chemotherapy, and anti-VEGF antibody therapy were associated with a significantly higher incidence of SP. Multivariate analysis identified that construction of a temporary loop colostomy in the right transverse colon during rectal cancer surgery (odds ratio, 5.07; 95% confidence interval, 1.12-22.86) is an independent risk factor.
Conclusions: In this study, multivariate analysis showed that the right side of the transverse colon was a risk factor for SP. Therefore, when constructing a transverse colon loop stoma, the stoma should be constructed in the left transverse colon to prevent SP.
