EXPERIANCE OF COLONOSCOPY AT A TERTIARY HOSPITAL, ADISS ABABA, ETHIOPIA

ABSTRACT Aims/Purposes: Currently colonoscopy has become one of the gold standard investigation modality for many colon and distal ileum pathologies. Its accuracy and success is highly dependent on many amendable factors such as bowel preparation and patient sedation. The quality of colonoscopy service should be measured in any institute regularly. Objectives: To assess the clinical indications and colonoscopy outcomes among patients seen at St. Paul’s Hospital Millennium Medical College Method: Institutional based cross-sectional study was conducted among 608 patient. Data of patients who were investigated with colonoscopy at St. Paul’s hospital endoscopy unit from February 1, 2016 – January 31, 2017 E.C. was evaluated. Results: The mean age of patients in this study was 45.8 years. Analgesia and sedation was not given for 6.1% of patients. Inadequate bowel preparation (22%) was the sole reason for all completely abandoned colonoscopies and it was the single most preventable cause of incomplete colonoscopies. Colonoscopy completion rate was 76%. The commonest colonoscopy finding in this study was haemorrhoidal diseases (29.8%). The diagnostic yield was 72.5%. The only documented complication was post procedure intra luminal bleeding in 2 (0.3%) patients.Conclusion: There was low polypectomy, colonoscopy completion and bowel preparation rates compared to the standard. The colonoscopy completion rate was lowest for those with inadequate/poor bowel preparation with significant statistical association. The technique of bowel preparation should be revised.Key words: Colonoscopy, cecal intubation, complete colonoscopy, bowel preparation, colonic polyp
