title: Usefulness of endoscopic treatment for duodenal adenoma.
abstract: In recent years, due to the increasing prevalence of upper gastrointestinal endoscopy, there have been an increasing number of reports on duodenal adenoma and early stage cancer. However, endoscopic techniques for the resection of duodenal adenomas are difficult, due to the anatomical features of the duodenum, and the long distance to the lesion. There have only been a few reports on the use of endoscopic techniques for duodenal adenomas compared to those focused on the stomach and large intestine. For duodenal adenomas, we used a conventional endoscope for lesions proximal to the major duodenal papilla, and a short-type double balloon endoscope for lesions distal to the papilla. The en-bloc resection rate was 93.8%. There was only one case of microperforation. Endoscopic manipulation is considered difficult in the deep areas of the duodenum, but double balloon endoscopy enabled stable manipulation and successful resection of the tumor in the majority of cases.
