ENDOSCOPIC MUCOSAL RESECTION IN THE SECOND POTION OF THE DUODENUM-REPORT OF 3 CASES-

Abstract

Three cases of sessile protruded lesion in the second portion of the duodenum perfomedendoscopic mucosal resection (EMR) are reported. ln each case, the lesion was completelyresected by‘strip biopsy’ using 2 channel endoscope (2 cases w/ith the Olimpus GIF-2T200, 1 case with the Olimpus XGIF-2TK200) . Histologically they vvTere diagnosed as duodenaltubular adenoma, carcinoid tumor, and atypical hyperplasia of Brunner's gland, respectively. Resected margins were free of lesion in all cases. Hemorrhage occurred in 2 cases, butboth cases recovered byendoscopic and conservative treatment.
It is possible to perform EMR in the second potion of the duodenum as well as in thestomach and colon, but the choice of endoscope depending on the region of lesion and thepreparation for avoiding complication were thought to be necessary.
