[Experience on the use of extra slim gastrointestinal endoscopes in ileal conduit endoscopy].

Using extra slim gastrointestinal endoscopes, we have examined ileal conduits in two patients. This endoscope has almost the same caliber as a flexible cystoscope and has multiple manipulation levers and channels as ordinal gastrointestinal endoscopes. It is often difficult to examine ileal conduits with flexible cystoscopes because ileal conduits lack continent mechanisms and cannot be dilated adequately with water irrigation. With air insufflations, extra slim gastrointestinal endoscopes could adequately distend ileal conduits, and with multiple levers, they provided much more freedom of manipulation than flexible cystoscopes. Visualization of ureterointestinal anastomosis sites and biopsy of tumors could be performed very easily. We strongly recommend the use of extra slim gastrointestinal endoscopes than flexible cystoscopes when retrograde examinations and procedures are necessary in patients with ileal conduits.
