An appraisal of intestinal stomas at a tertiary hospital in South Western, Nigeria

Abstract

Background: Intestinal stomas are frequently constructed as part of abdominal surgeries in our center especially for colorectal cancer (CRC). There has been no previous documentation of the experience at our tertiary center. Objective: The objective of this study is to document the indications, types, and complications of intestinal stomas in our center to make necessary recommendations. Patients and Methods: This was a retrospective descriptive study of all patients who had intestinal stomas constructed during a 4-year period. The demographic data of patients, the information on indications, types, and complications of intestinal stomas were obtained from theatre records, and case notes. Data were analyzed using SPSS version 23. Results: A total of 85 intestinal stomas were constructed during the study period. Forty-four (51.8%) were males and 41 (48.2%) females with a male-female ratio of 1.07 to 1. The common indications were large bowel obstruction due to CRC (21.2%), anastomotic dehiscence (15.3%), and rectal/sigmoid injuries (12.7%). The intestinal stomas constructed in patients included defunctioning stomas (61.2%), decompression stomas (31.8%), permanent end colostomy following abdominoperineal resection of rectum for cancer (3.5%), and palliative sigmoid colostomy (3.5%) in patients with anal cancer. Sigmoid loop was the commonest stoma, constructed in 26 patients (30.6%). The common complications were peristoma skin excoriation (53.5%), retraction (11.6%) pouch leakage (9.3%), and prolapse (9.3%). Conclusion: Malignant intestinal obstruction due to CRC was the most common indication for stoma construction at our institution. Consequently, massive health education campaign to ensure early presentation of CRC is needed to reduce the need for stoma creation.
