A CASE OF INTRALUMINAL DUODENAL DIVERTICULUM(IDD) TREATED BY ENDOSCOPIC EXCISION

Abstract

A 32-year-01d woman visited our hospital complaining of postprandial epigastralgia andvomiting. She had occasionally had the same symptom from childhood. Hypotonic duQdenography revealed a barium-filled pear-shaped sac surrounded by thinradiolucent line in the second part of duodenum. The findings are most suggestive ofintraluminal duodenal diverticulum.(IDD). We performed an endoscopic excision of IDD with2-channel fiberscape. After inversion of the diverticular sac to the oral side by forceps, sac wasexcised by polybectom.y-snare with a high voltage electric current. Histological findings of theexcised specimen revealed normal duodenal mucosa on both sides of the sac. After this excisionshe obtained eomplete relief of the symptom. IDD is a rare congenital anomaly of the duodenum As far as we know, 45 cases of IDDincluding our case have been reported in Japan. furthermore, endoscopic removal of thediverticular sac would be a minimal invasive and effective method in the rnanagement of IDD.
