[A Case of Left Upper Abdominal Evisceration for Transverse Colon Cancer with Multiple Organ Invasion].

The case is a 73-year-old woman. She visited primary care doctor for abdominal pain, vomiting, diarrhea, and melena that persisted for 2 weeks. She was referred to our department because she had an elevated inflammatory response and CT showed a mass in her left upper quadrant. Contrast-enhanced CT showed a tumorous lesion mainly in the splenic flexure of the transverse colon, involving the greater curvature of the stomach, the tail of the pancreas, and the hilus of the spleen, accompanied by abscess formation. We suspected highly advanced colon cancer with multiple organ involvement, but we opted for multiple visceral resection because it was associated with high-grade inflammatory findings due to abscess formation. After she was treated with antibiotics, she underwent laparotomy on the 6th day of illness. Intraoperative findings showed no clear nodular lesions suggesting dissemination in the abdominal cavity and intraoperative washing cytology was negative. Since the mobility of the mass that invaded the posterior wall of the greater curvature of the stomach, the tail of the pancreas, and the splenic hilum centered on the splenic flexure was confirmed, the entire left upper abdominal evisceration was resected by resecting the splenic flexure of the colon, the stomach, the tail of the pancreas, and the spleen. The postoperative course was uneventful, and she was discharged on postoperative day 9. Histopathological examination confirmed invasion of colon cancer into the pancreas, spleen, and retroperitoneum. In this report, we present a case of colon cancer with multi-organ invasion that underwent left upper abdominal evisceration.
