Abstract
Case 1 involved a 74-year-old man with a several-day history of appetite loss presented to the Critical Care Center in our hospital because of the abrupt onset of abdominal pain. A contrast-enhanced abdominal CT scan showed a tumor in the transverse colon at the splenic flexure and its direct invasion into the stomach. Colonoscopy revealed a tumor of the transverse colon completely encircled the colon. Upper gastrointestinal series revealed infiltrating findings of an extramurally growing tumor in the middle portion of the gastric body. A biopsy of the colon showed poorly differentiated adenocarcinoma. Cancer of the transverse colon with a resultantly caused gastrocolic fistula was diagnosed. Left hemicolectomy and segmental resection of the stomach were performed.
Case 2 involved an 87-year-old man with a 2-week history of appetite loss and right upper quadrant pain. He visited a neighboring hospital and was referred to our hospital with a suspicion of an intraabdominal tumor. A contrast-enhanced abdominal CT scan showed a tumor in the transverse colon at the hepatic flexure. Upper gastrointestinal series showed infiltrating findings of an extramurally growing tumor at the pyloric antrum. A biopsy of the colon revealed poorly differentiated adenocarcinoma. Cancer of the transverse colon with a resultantly caused gastrocolic fistula was diagnosed. Right hemicolectomy and distal gastrectomy were performed.
We present these two cases of cancer of the transverse colon causing a gastrocolic fistula.
