A 49-year-old male was admitted to our hospital due to abdominal pain and nausea. Small bowel fluorography showed complete obstruction of the jejunum 30cm anal side from the ligament of Treitz. The endoscopic examination was performed with an intestinal fiberscope (Olympus X-SIF10) . There was an elevated lesion with granular and irregular surface similar to a villous tumor of the colon. The fiberscope did not pass the tumor to the anal side. Biopsy specimen showed moderately differentiated adenocarcinoma. Jejunal resection with lymph node dissection was performed followed by end to end anastomosis.
There has been 50 cases of small intestinal cancer except duodenal cancer literally reported in Japan, which could be diagnosed preoperatively by intestinal endoscopy and our classification of those cancer is shown.
