Abstract: | BACKGROUND: Patients with chronic abdominal pain consult gastroenterologists frequently, requiring a large number of examinations. AIM: To assess the diagnostic yield of capsule endoscopy in patients with chronic abdominal pain of unknown origin and negative diagnostic work-up. PATIENTS: From January 2002 to September 2004, 16 patients (10 female; mean age 42.7 years) who complained of chronic abdominal pain were referred to our unit for capsule endoscopy. METHODS: Chronic abdominal pain was defined as continuous or almost continuous, for at least 3 months and without criteria for other gastrointestinal disorders. All patients had a previous diagnostic work-up including abdominal ultrasonography, oesophagogastroduodenoscopy, colonoscopy and small bowel follow through, performed within 2 months. RESULTS: Capsule endoscopy was normal in 12 patients (75%). Small bowel abnormalities were found in three patients, but were considered irrelevant. In one patient (6.3%), capsule endoscopy revealed ileal erosions and inflammation and was retained in a stricture undetected by radiology. This patient underwent elective surgery which revealed an ileal carcinoid neoplasm. CONCLUSIONS: Capsule endoscopy identified a specific cause of chronic abdominal pain in only one patient. Capsule endoscopy is a safe procedure but does not seem to play an important role in the evaluation of patients with chronic abdominal pain of unknown origin. |
