Endoscopic incision of the duodenal descending incomplete obstruction caused by duodenal web (with video)

A 61-year-old woman was referred to our hospital because she had experienced postprandial epigastric satiety for 10 years. The GI barium study showed a pocket-like structure in the descending duodenum (A, arrow), and contrast-enhanced CT of the abdomen showed dilatation of the descending part of the duodenum with obstruction. A membranous stenosis with a small pinhole opening was observed in the descending part of the duodenum, and the papilla of Vater was observed in the medial wall by endoscopy (B, arrow).
