[A Case of Ileal Carcinoma Diagnosed under the Examination for Intestinal Obstruction after Gastric Surgery and Performed Laparoscopic Resection].

A 69-year-old man presented to our hospital with chief complaints of epigastral pain and nausea, was diagnosed with intestinal obstruction after gastric surgery. Abdominal CT performed on the admission showed the tumor located on the terminal ileum. On colonoscopy, type 1 cancer was found near the Bauhin valve in the ileum, and suspected primary ileal carcinoma. Laparoscopic ileocecal resection was performed. The pathological diagnosis was moderately differentiated adenocarcinoma, and the pathological stage was T3(SS), N1(3/16), M0, Stage ⅢA. Although superficial surgical site infection was occurred, the patient was discharged 11 days after surgery. He hoped to adopt without adjuvant chemotherapy, so he has been followed as outpatient. Twenty one months since the surgery, there has been no evidence of cancer recurrence.
