Colonoscopy in a Tertiary Hospital in Nigeria
Background: Colonoscopy is an accurate method of diagnosing colonic disease but is technically demanding and operator dependent. Colonoscopy is not a common procedure in Nigeria. After the restructuring of the endoscopic unit of a tertiary hospital in Nigeria, a preliminary survey was carried out with the aim of determining the diagnostic yield and spectrum of cases seen. Methodology: Results of colonoscopies performed by surgeons in the endoscopic unit of the Jos University Teaching Hospital, a tertiary medical centre in Plateau State, Nigeria were retrospectively analysed for a period of 6 months. The diagnostic yield and findings were analyzed. Results: A total of 43 colonoscopies were performed, the mean age was 43.5 years (range, 8 to 80 years). Male patients were 28. Most (82%) were performed on outpatient basis. Diagnostic yield was 79%. The most common pathology found was haemorrhoids (58.1%). Normal colonoscopy was the outcome in 20.9% of patients. Other lesions were polyps (6.9%) and cancers (4.7%). Multiple lesions were found in 5 patients (10.9%). Conclusion: Haemorrhoids are the most common lesions presently found in patients undergoing colonoscopy performed by surgeons in Jos University Teaching Hospital. Polyps and cancers are found less commonly.
