| Core Tip |
Carbon dioxide insufflation enterography (CDE) may be useful for selecting route at branch in patients with altered gastrointestinal anatomy in double-balloon endoscopy. The endoscopist inserts the tip of the endoscope into one of the two tracts at the branch and insufflate carbon dioxide with an obstruction created by the inflation of an endoscopic balloon. Fluoroscopy is used to determine the direction of carbon dioxide flow. This prospective study evaluated the usefulness of CDE during double-balloon endoscopic retrograde cholangiography in patients with altered gastrointestinal anatomy by prospectively investigating the accuracy of route selection using CDE at the branch of the anastomosis. The mean procedure times from the teeth to the target (total insertion time), from the teeth to the branch, and from the branch to the target, and the mean total examination time were 15.2, 5.0, 8.2, and 60.3 min, respectively. The rate of correct route selection using CDE in patients with a jejunojejunal anastomosis was 29/33 (87.8%), and the rate in patients with a gastrojejunal anastomosis was 19/19 (100%). |
