MUCUS SECRETING POLYP OF THE DUODENUM

Abstract

This paper describes 18 cases of duodenal polyp with mucus secretion. The polyp in 15 cases out of them was localized in the duodenal bulb. The structure was hemispherical in contour, measuring about 1 cm. in diameter. The small orifice-like formation with the transparent mucus secretion was recognized through endoscopic observation. 4 types of orifice shape were noted endoscopically. The lumen connected to the orifice was found under dissecting microscopy. The wall of the lumen was composed of villous projections with gastric epithelium. Brunner's gland drained into the lfmen. Of the 18 patients, 17 were male and one was female. The age varied from 41 to 74 years. The complaints of the patients were nonspecific and their relation to the polyp was questionable. Enlargement, bleeding, obstruction and malignant change were not recognized through the follow-up study.
