Two Cases of Simultaneous Laparoscopic Surgery for Synchronous Gastric and Colon Tumors

Here we report two cases of the simultaneous laparoscopic surgery. Case 1 was a 63-year-old male who was referred to our hospital for the treatment of co-existing gastric cancer (T1aN0M0) and colon cancer (T1N0M0). We simultaneously performed laparoscopic sigmoidectomy and distal gastrectomy. It took 525 minutes and blood loss was 200 ml. Case 2 was a 77-year-old female who was referred to our hospital for the treatment of a low-risk gastrointestinal stromal tumor of the stomach co-existing with colon cancer (T2N0M0). We simultaneously performed laparoscopic ileocecal resection and partial resection of the stomach. The gastric tumor was treated by laparoscopic and endoscopic cooperative surgery. It took 451 minutes and the total blood loss was 100 ml. Each patient was discharged on postoperative day 13 without any complications. We believe that simultaneous laparoscopic surgery for synchronous malignant tumors under the guidance of an experienced surgeon is feasible and minimizes postoperative distress
