Since the introduction in 2001 of M2A video capsule imaging of the small bowel in humans, this technique has been used increasingly in patients with disorders of the small bowel. In particular the assessment of small obscure gastrointestinal bleeding sources and the detection of shallow inflammatory lesions in the small bowel, have been greatly facilitated by this novel imaging procedure. We report two cases of patients with obscure gastrointestinal bleeding, in whom normal passage of the capsule through the antroduodenal junction was inhibited. This was because of delayed gastric emptying in both patients, which was presumably caused by functional impairment of pyloric motility. To facilitate capsule transport into the small bowel, after swallowing the capsule each patient underwent unsedated upper gastrointestinal endoscopy during which the capsule was grasped with a polypectomy snare, directly transported through the pylorus, and finally released upon arrival in the second portion of the duodenum. Capsule recordings revealed the source of bleeding in both patients and their medical or surgical treatment was subsequently escalated. Capsule imaging of the small bowel facilitated by esophagogastroduodenoscopy (EGD) is safe, and can be applied when patients have functional disorders of pyloric motility.
