AIM:Capsule endoscopy has demonstrated its clinical utility in the evaluation of small bowel pathology in several Western studies.In this prospective study,we aimed to determine the clinical utility,safety and tolerability of capsule endoscopy in the evaluation of suspected small bowel disease in an urban Southeast Asian population. METHODS:We used the given (M2A) capsule endoscopy system in 16 consecutive patients with suspected small bowel pathology.In 9 patients the indication was obscure gastrointestinal bleeding,while in 6 patients it was to determine the extent of small bowel involvement in Crohn's disease.One patient underwent capsule endoscopy for evaluation of chronic abdominal pain.Patient's tolerability to the procedure was evaluated by standardized questionnaires and all patients were reviewed at one week to ensure that the capsule had been excreted without any adverse events. RESULTS:Abnormal findings were present in 8 patients (50%).The cause of obscure gastrointestinal bleeding was determined in 5 out of 9 patients.Findings included 2 cases of angiodysplasia,2 cases of jejunal ulcers and 1 case of both angiodysplasia and jejunal ulcer.One patient had small bowel erosions and loci of erythema of doubtful significance. Ileal lesions were diagnosed in 2 out of 6 patients with Crohn's disease.Capsule endoscopy was well tolerated by all patients.One patient with Crohn's disease had a complication of capsule retention due to terminal ileum stricture.The capsule eventually passed out spontaneously after i month. CONCLUSION:Our study,which represented the first Asian series,further confirms the diagnostic utility,safety and tolerability of wireless capsule endoscopy.

One patient had small bowel erosions and foci of erythema of doubtful significance.Ileal lesions were diagnosed in 2 out of 6 patients with Crohn's disease. Capsule endoscopy was well tolerated by all patients. One patient with Crohn's disease had a complication of capsule retention due to terminal ileum stricture. The capsule eventually passed out spontaneously after 1 month.CONCLUSION: Our study, which represented the first Asian series, further confirms the diagnostic utility, safety and tolerability of wireless capsule endoscopy.
