Diagnostic value of ileoscopy: a report from India.

Our aim was to present a report about the usefulness of ileoscopy as an adjunct to colonoscopy, as studied in India, in the face of a dearth of such reports from the developing countries and to study the role of ileoscopy in increasing the yield of diagnosis reached and modified. In a prospective study in 66 consecutive patients undergoing colonoscopy for various indications, colonoscopy/ileoscopy was performed with a forward viewing fiberoptic colonoscope. Details of ileal mucosa, time taken to reach ileum, and length of ileum intubated were noted. Of the 66 patients undergoing colonoscopy, cecum could be reached in 62, whereas ileum was successfully intubated in 57 (86.4%). In 13 (22.5%) cases, additional information was obtained. In eight (14.4%) cases, diagnosis was established on ileoscopy. Of these, two were of lower gastrointestinal (GI) bleed (typhoid ulcer and nonsteroidal antiinflammatory drug ulcer), one had lymphoma, two had tuberculosis, and three were cases of reactive arthritis with ulcers in terminal ileum. After ileoscopy, the diagnosis was altered in five (8.7%) cases. Time taken to reach ileum from cecum was 3.3 +/- 2.5 minutes and the length of examined ileum was 17.3 +/- 7.5 cm. Ileoscopy is a useful adjunct to colonoscopy that not only helps to modify the diagnosis but also established them.
