A case of laterally-spreading tumor in a colonic interposition after esophageal cancer treated by endoscopic submucosal dissection

Abstract

A 73-year-old male patient underwent esophagectomy and reconstruction using a colon via antethoracic route for esophageal cancer in 1994. He had been followed up with an upper gastrointestinal endoscopy for five years after surgery. He presented to his family physician with fever and coughing. His doctor introduced him to the department of the pulmonary disease at our hospital because of the elevation of CEA and CYFRA. He received CT and PET. PET showed SUV uptake in colonic interposition. He received an upper gastrointestinal endoscopy and laterally spreading tumors were identified. These lesions were considered a good candidate for endoscopic resection. The lesions were safely and completely removed by ESD and EMR. Histological examination diagnosed the specimen as high grade tubular adenoma. The patient was hospitalized for 4 days after endoscopic treatment to confirm the absence of complications such as delayed perforation and bleeding, and was then discharged.
Upper endoscopic screening is recommended after five years follow up of colonic interposition and lesions may be detected early and removed safely by endoscopy.
