Endoscopic reduction of gastric antrum herniation through the foramen of Winslow into the lesser sac

Abstract

urgent colonoscopy was carried out. Many diverticula were observed on the right side of the colon without active bleeding and blood clots. Some diverticula were very small; therefore, it was difficult to observe inside them. However, by using water immersion and the water jet function, the insides of these diverticula were clearly observed, and a diverticulum with a white plug was detected ( Fig. 2; Video S1). After marking near this diverticulum with a hemoclip, it was treated by elastic band ligation. Bleeding was caused by aspiration of the diverticulum, but stopped immediately. Bleeding did not recur after the treatment.In summary, a clear image is needed in order to identify the stigmata of recent hemorrhage in colonic diverticular bleeding. Water immersion observations represent a useful method for identifying the stigmata of recent hemorrhage.Authors declare no conflicts of interest for this article.
