Simultaneous Totally Laparoscopic Distal Gastrectomy and Anterior Resection for Synchronous Gastric and Colon Cancer.

Although simultaneous open surgery for synchronous gastric and colon cancer has been reported frequently to date, total laparoscopic resection has been documented rarely. A 63-year-old male patient who presented with complaints of abdominal pain and constipation was diagnosed with synchronous gastric and sigmoid colon cancer. Simultaneous total laparoscopic distal gastrectomy (Roux-en-Y anastomosis and D2 lymph node dissection) and anterior resection were performed with a total of five ports. Total operation time was 310 min. and estimated blood loss was 175 mL. Histopathological examination result was reported as well-differentiated adenocarcinoma for the stomach and moderately differentiated adenocarcinoma for the colon. Staging result was Stage IIA (pT3N0M0, American Joint Committee on Cancer (AJCC) 8th Edition) for both cancers. The patient received postoperative adjuvant chemotherapy. He remains under follow-up at 21 months without any recurrence. With the improved techniques and increased experience in minimally invasive surgery, combined laparoscopic curative resection can be safely performed for gastric and colon cancer.
