Synchronous Bilateral Flexure Tumor Causing Ileus and Requiring Surgical Treatment

This case report presented a simultaneous right colon tumor detected perioperatively in a patient who developed ileus due to a metastatic left colon tumor in the preoperative period. A seventy-six-year-old man was admitted with epigastric pain, nausea, and vomiting. There was tenderness and defense on deep palpation on the epigastrium. On computed tomography, there were multiple hypodense lesions on the liver, a mass at the level of the splenic flexure that obliterates the lumen. In addition, there were numerous air-fluid levels due to tumoral mass on splenic flexure. Emergency surgery was performed, and during surgery, there were tumoral masses at the hepatic flexure and splenic flexure. Palliative total abdominal colectomy with end ileostomy was performed due to megacolon. The patient died due to sudden cardiac arrest on the 1st postoperative day.
