AIMS and Objectives: The purpose of the study was to explore the causes of lower GI bleeding and correlate them with colonoscopic findings.
Materials and Methods: In this study, a total of 80 patients who presented to Yenepoya medical college from January 2019 to September 2019 with at least one episode of per rectal bleeding were taken and colonoscopy was performed for all patients. The clinical diagnosis at the time of presentation and the colonoscopic findings were compared and the results tabulated.
Results: The most common causes of lower GI bleeding included haemorrhoids, colitis and colorectal malignancies. Colonoscopy findings were found to be normal only in 2.8% of patients, as compared to 22.8% on clinical diagnosis. The sensitivity and specificity of the clinical symptoms and signs was very low. The clinical diagnosis made was correct in 40% of the cases.
Conclusion: 1) The more frequent endoscopic findings were colitis, colorectal malignancies and polyps. 2) Clinical data are of little value in predicting a normal examination. 3) Total colonoscopy appears to be the first procedure of choice in all patients with lower gastrointestinal bleeding, irrespective of the clinical data and the presence of anal pathology. 4) Symptoms are unhelpful in deciding who requires investigation.
