Laparosocpy-assisted pylorus-preserving gastrectomy (LAPPG) is a widely accepted surgical procedure for the treatment of early gastric cancer in the middle third of the stomach. We have been performing this operation since 2007. Compared with traditional distal gastrectomy, LAPPG has postoperative nutritional benefits for patients. However, this procedure preserves only the pyloric branch of the vagus nerve and not the celiac branch. We found that patients retain a large amount of residual food in the gastric remnant, which interferes with the detection of secondary cancer on endoscopic follow-up. To improve the pyloric function and postoperative gastrointestinal motility, we changed our procedure during 2009 to preserve both the pyloric and celiac branches of the vagus nerve, and we named this new procedure laparoscopy-assisted vagus nerve and pylorus-preserving gastrectomy (LAVNPPG). From 2009 to 2011, 11 patients underwent LAVNPPG at our hospital. Retrospective comparison of the safety of operation, postoperative complications, and condition of the gastric remnant between LAPPG (n=13) and LAVNPPG (n=11) found that the occurrence of postprandial stasis and food residue in the gastric remnant tended to be lower following LAVNPPG, though the differences were not significant. These findings indicate that LAVNPPG may be an operative procedure that could replace LAPPG.
