The preferred investigations for lower GI bleeding are colonoscopy plus video capsule endoscopy. Colonoscopy has been the gold standard for the diagnosis of colonic bleeding. The risk of colonoscopy-induced complications such as bleeding or perforation is less than 1 in 3500. Video capsule endoscopy is a non-invasive, safe and accurate technology that has been approved by the FDA for investigation of small bowel diseases. The video capsule is an 11x 26mm capsule that encases a digital camera, light-emitting diodes, batteries, and a transmitter. The patient needs to swallow the video capsule after an overnight fast and wear a recording device for eight hours. Images are taken twice-per-second and transmitted to the recording device. Oral feeding can be resumed after four hours. There is no restriction to daily activities. The swallowed capsule will be expelled naturally after 5 to 12 hours virtually in all patients. The risk of capsule retention is very low and only occurs in patients with severe small bowel stricture.
