Abstract:
INTRODUCTION: Bleeding per rectum is not an infrequent complaint during pregnancy, which may require endoscopic evaluation and treatment. Flexible sigmoidoscopy is a relatively simple, quick procedure. The current study was aimed to assess the usefulness of flexible sigmoidoscopy in bleeding per rectum during pregnancy from a single tertiary care centre. METHODS: A single centre retrospective study was carried out. Randomly selected 1000 medical records of the pregnant mothers who were referred as out patients and hospitalized from 2012 to 2022 were retrieved. All patients had the passage of fresh blood as their chief complaint. All of them had not undergone any prior diagnostic workup for their presentation. All had undergone flexible sigmoidoscopies and patients with significant additional bowel symptoms underwent colonoscopy following sigmoidoscopy. Endoscopic findings were recorded in a computer based database. Ethical approval was obtained from the Ethical Review Committee of Nawaloka Hospitals of Sri Lanka. No conflict of interest. RESULTS: A total of 48 pregnant women had undergone lower GI endoscopies. The mean age of the patients was 25.3 ± 6.5 years. Twenty-four patients (50%) were primigravida. Majority was in the second trimester of pregnancy 89.5% (43/48). The mean (±SD) gestational age at the time of procedure was 18(±2) weeks. All had undergone sigmoidoscopy, and an additional colonoscopy were done in 2 patients. Bleeding per rectum was the main indication. All flexible sigmoidoscopies were done without sedation. Wiliest, the colonoscopies were performed under conscious sedation. Majority of the pregnant mothers found to have haemorrhoids followed by anal fissures (46/48; 95.8%). Ulcerative colitis and a sigmoidal cancer were found in two patients (4.2%). None had an immediate post procedure-related complication. CONCLUSION: Flexible sigmoidoscopy is useful and safe to be performed in pregnancy with clinically significant bleeding per rectum. It has a good diagnostic yield. Further prospective multicentre research studies are strongly recommended.
