Six cases of simultaneous reduced port laparoscopic surgery for synchronous gastric and colorectal cancer

We report 6 cases of simultaneous resection of synchronous gastric and colorectal cancer using a multichannel port and an additional 5-mm port. This is the first report of simultaneous gastric and colorectal resection using a reduced port technique. A multichannel port was inserted into an umbilical incision, and another 5-mm port in the right flank region. We named this approach ‘‘dual port surgery.’’ This report includes a 76-year-old man who underwent total gastrectomy and left hemicolectomy, a 70-year-old woman who underwent distal gastrectomy and high anterior resection, a 75-year-old man who underwent distal gastrectomy and right hemicolectomy, a 72-year-old man who underwent total gastrectomy and sigmoidectomy, a 67-year-old man who underwent distal gastrectomy and high anterior resection, and a 57-year-old woman who underwent distal gastrectomy and right hemicolectomy. All operations were successful. All patients recovered quickly, and were discharged without any intra- or postoperative complications. On a median follow-up of 14.5 months, all patients remain well with no evidence of recurrent malignancy. This is the first report of simultaneous reduced port laparoscopic surgery for synchronous gastric and colorectal cancer. This procedure was performed safely and successfully.
