[A Case of Small Bowel Adenocarcinoma That Was Diagnosed and Treated using Laparoscopic Surgery].

A 40-year-old man presented to our department with chief complaints of nausea and abdominal pain, and was diagnosed with small intestine ileus. After hospitalization, he underwent intestinal tract decompression using an ileus tube. A small bowel tumor was suspected as the cause of the intestinal obstruction. We then performed laparoscopic surgery for diagnosis and resection. In the intraoperative findings, stenosis near the small intestine tumor could be confirmed. The patient therefore underwent laparoscopic resection of a segment of the small intestine. Following rapid intraoperative pathological examination, the tumor was identified as well-differentiated adenocarcinoma with metastasis of the intermediate mesenteric lymph nodes. We then performed dissection of the main lymph nodes using small laparotomy incisions. Adjuvant chemotherapy with XELOX(130mg/m2 L-OHP on day 1 and 2,000 mg/m2 capecitabine on days 1-14)was administered for 6 months. Currently the patient is in relapse-free survival.
