Introduction.

Benign colorectal stenosis refers to an anatomical condition characterized by a decrease in the diameter of the intestinal lumen distal to the ileocecal valve, which might cause a series of obstructive signs and symptoms. It is a rare entity, caused in the vast majority of cases due to intestinal anastomosis at the described level. The purpose of this study is to determine the performance of colonic stents in the management of non-malignant colorectal strictures.

Methods.

Descriptive study of a cohort of patients who developed a benign colorectal stenosis confirmed by colonoscopy in three high-complexity hospitals in the city of Medellín, Colombia, between 2007 and 2021.

Results.

Thirty-four patients diagnosed with benign colorectal stenosis managed with self-expanding metal stents were included in the study. Median follow-up was 19 months, obtaining clinical success in 73.5% of cases, with a complication rate of 41.2%, mainly due to reobstruction and migration of the stent, and to a lesser extent due to perforation secondary to device placement.

Conclusion.

Self-expanding metallic stents represent a therapeutic option in patients with colorectal obstruction caused by non-malignant stenosing pathology. When diversion through a stoma is not an option, this type of device is associated with high rates of clinical success and improvement in the patients’ quality of life.
