Abdominal surgery for gastric cancer following coronary artery bypass grafting using an in situ right gastroepiploic artery graft.

Background: The right gastroepiploic artery (RGEA) is often used for coronary artery bypass grafting (CABG) in Japan. As gastric cancer has a high prevalence in many Asian countries, we investigated problems with surgery for gastric cancer after CABG using the RGEA.

Methods: A total of 860 patients underwent CABG using the RGEA between January 1997 and December 2006. Of these, 13 patients underwent surgery for gastric cancer after CABG. In all cases, the RGEA was harvested by the skeletonization technique, and an antegastric route was used for the anastomosis.

Results: Dissection for the No. 6 lymph node was not performed in all cases because of the risk of graft injury. Graft injury during gastric surgery occurred in one patient and post-operative ventricular fibrillation (VF) was observed in two patients. One case of hospital death due to VF and two cases of remote death were encountered.

Conclusions: In planning a resection for gastric cancer following a CABG with a patent RGEA graft, the potential for graft injury must be anticipated. In advanced stages of gastric cancer when the RGEA needs to be resected to dissect the No.6 lymph node, a pre-operative percutaneous coronary intervention or a reoperative CABG may be indicated.
