RESUMO
Background. Colonoscopy effectiveness depends on the quality of the examination. Community-based report of quality of colonoscopy practice in a developing country will help in determining standard and also serve as a stimulus for improvement in service. Aim. To review the quality of colonoscopy practice and document pattern of colonic disease including polyp detection rate in Lagos, Nigeria. Method. A protocol that captured the patients' demographics, indication, and some quality indices of colonoscopy was developed and sent to all the identified colonoscopy units in Lagos to complete for all procedures performed between January 2011 and June 2012. All data were collated and analyzed. The quality indices studied were compared with guideline standard. Results. Twelve colonoscopy centers were identified but only nine centers responded. The gastroenterologist/endoscopists were physicians (3) and surgeons (5). Six hundred and seven colonoscopy procedures were performed during this period (M : F = 333 : 179) while the sex was not disclosed in 95 subjects. The examination indications were lower GI bleeding (24.2%), altered bowel habits (9.2%), lower abdominal pain (9.1%), screening for CRC (4.3%) and unspecified (46.8%). Conscious sedation was generally used while bowel preparation (good in 81.4%) was done with low residue diet and stimulant laxatives. Caecal intubation rate was 81.2%. Common endoscopic findings were haemorrhoids (43.2%), polyps/masses (13.4%), diverticulosis (11.1%), and no abnormality (23.4%). Polyp was detected in 6.8% of cases. Conclusion. Colonoscopy utilization is low, and the quality of practice is suboptimal; although limited resources could partly explain this, however it is not clear if the low rate of polyp detection is due to missed lesions or low population incidence.
RESUMO
BACKGROUND: The advent of flexible endoscopy has made it possible to visualise the mucosa of virtually the entire intestine. This service is yet to be widely available in Nigeria. Existing reports on indications and findings at endoscopies are sometimes conflicting, with some recent reports suggesting a changing pattern of gastrointestinal diseases. OBJECTIVE: The study set out to evaluate the indications, endoscopic findings and their frequencies as well as any adverse outcome from the endoscopic examinations. METHODOLOGY: This was a retrospective study in which we reviewed the endoscopy records of the first one hundred and seventy patients that underwent upper gastrointestinal endoscopy at the Lagos State University Teaching Hospital. The patients' bio data, indications and findings during endoscopic examinations as well as any adverse outcome were documented. Data obtained were analysed using SPSS version 11. RESULTS: The majority of the patients were in the middle to elderly age with a peak in the 5th decade. The commonest indications for upper gastrointestinal endoscopy were; Dyspepsia, upper gastrointestinal haemorrhage, previously diagnosed peptic ulcer unresponsive to treatment and retrosternal discomfort or pain. Endoscopic request for variceal screening were uncommon. The commonest endoscopic findings were; features of gastroesophageal reflux disease, followed by gastroduodenitis (non-ulcer mucosal lesions in stomach and duodenum) and peptic ulcer disease. In 14 patients the endoscopy examination revealed normal findings. CONCLUSION: The role of endoscopy in the diagnosis and management of gastrointestinal disorders cannot be overemphasised. It is hereby recommended that provision of endoscopic facilities and training of necessary personnel be encouraged by all relevant agencies so that the services can be accessible and affordable by all who require it in view of its importance in patient management.
