Table of Contents

Capsule endoscopy was recently introduced for endoluminal visualization of the small bowel [1]. The clinical utility of the procedure is undisputed [2] [3] [4], and for most patients, swallowing the capsule (11 × 33 mm in size) does not pose any problems.

A 74-year-old woman presented with melena and severe iron-deficiency anemia. She was admitted to the local hospital, where upper endoscopy was initially unsuccessful due to a 3-cm Zenker’s diverticulum. A repeat upper endoscopy was carried out the next day; the diverticulum was negotiated during this procedure, but no source of bleeding was found. Colonoscopy revealed only tarry stools and probable small-bowel bleeding. Because of continued bleeding and a need for repeated transfusions, the patient was referred for capsule endoscopy.

A guide wire was initially placed in the stomach to allow visualization of the passage alongside the diverticulum. The capsule was caught in a standard polypectomy snare through the endoscope. However, it was not possible to pass the capsule transversely through the esophageal slit in the diverticulum. Instead, a switch was made to a pediatric endoscope (Olympus GIF-XP160P, outer diameter 5.9 mm) and the capsule was fixed to the outside of the endoscope, approximately 25 cm from the distal tip, using an external polypectomy snare around the endoscope and the capsule (Figure [1]). The endoscope was then reintroduced into the esophagus and stomach. Passage of the capsule into the stomach was confirmed by retroflex viewing (Figure [2]), and the capsule was then released. Multiple bleeding angiodysplasias were visualized in several segments of the ileum, and the patient subsequently underwent resection.

In regular cases of difficulty in swallowing the capsule, the standard method of through-the-scope snaring works well. However, the method presented here represents a technically simple alternative in specific cases.
