Abstract

A 74-year-old man seen for anemic symptoms was found in abdominal computed tomography (CT) to have small -intestine wall thickening and an enlarged mesentery lymph node. Positron emission tomography (PET) showed a 4 cm tumor near the left pelvic intestinal tract. Double -balloon endoscopy showed a circumferential hemorrhagic type 2 tumor in the upper jejunum diagnosed as moderately differentiated adenocarcinoma based on site biopsy. The man was also diagnosed with primary small -intestine cancer and underwent partial small -intestine resection, local lymph node dissection, and functional end -to -end anastomosis. Histopathological findings yielded a final diagnosis of type 2 papillary adenocarcinoma, ly2, v1, pSS, pN1, sP0, sH0, and pM0. The postoperative course was satisfactory and he was discharged on postoperative day 12.
