Description
Background Most tertiary gastroenterology centers currently offer an open-access capsule endoscopy (CE) service, including patients with obscure gastrointestinal bleeding. However, CE may identify lesions missed by conventional endoscopy. Aims To determine the incidence of bleeding lesions missed by the preceding gastroscopy/colonoscopy that were revealed by CE and compare potential differences in the rate of identifying such lesions in patients that we investigated as opposed to those investigated elsewhere. Methods We prospectively reviewed data from patients subjected to CE for obscure bleeding. We analyzed all cases where a source of bleeding was located in the stomach, duodenum, or colon. Results A total of 317 consecutive patients were subjected to CE for obscure gastrointestinal bleeding within 28 months. Prior to CE examination, 174 patients had gastroscopy and colonoscopy in our institutions and 143 were referrals, all with negative endoscopic investigation. We identified 11 (3.5%) cases where the source of bleeding was found in the stomach (n = 4) or the cecum (n = 7). There was a significant difference of extra small intestinal lesions diagnosed by CE between referrals (9/143, 6.3%) and endoscopic investigation performed in our institutions (2/174, 1.15%), (p = 0.026). The estimated cost of re-endoscoping in our institution all CE referrals would be €50,050 (143 patients 9 €350), to avoid unnecessary CE examinations (9 patients 9 €600 = €5,400). Conclusions Reading the whole CE video is important, because small-bowel CE may identify lesions responsible for obscure bleeding missed by the preceding gastroscopy and colonoscopy. Repeating conventional endoscopy by experts before CE is not a cost-effective approach.
