[A Case Report of Laparoscopy Assisted Distal Gastrectomy for Gastric Cancer with an Adachi Type VI Anomaly (Group 27)Institution].

We report the case of a 79-year-old man, with gastric cancer detected on upper gastrointestinal endoscopic examination performed by a nearby medical clinic, and referred to our hospital, in April 201X. He was diagnosed with gastric cancer(ML, less, 0- II a+ II c, tub 1-2, cT1bN0M0, cStage I A). We performed laparoscopy assisted distal gastrectomy, D1+lymph node dissection, and Billroth I (B- I )reconstruction. Abdominal CT scan before surgery confirmed vascular anomaly of the celiac artery. We diagnosed Adachi type VI, preserved hepato-gastric artery trunk, and performed D1 plus dissection plus B- I reconstruction with small incision in the epigastrium. The operation time was 244 minutes and the blood loss was 5 mL. There were no postoperative complications, and the patient was discharged from hospital 7 days after the surgery. Pathological findings revealed pT4aN0M0, pStage II B, and the patient has been treated with TS-1®postoperative adjuvant chemotherapy. At present, there is no recurrence. As vascular anomalies of the celiac artery branch exhibit various forms, occasional blood vessel preventing surgery is required. Examining blood vessels through CT scan before the surgery made it possible to perform Laparoscopic gastrectomy safely.
