S043 mythbuster: truncal vagotomy and gastric drainage procedures.
INTRODUCTION: You are sitting for your oral surgery board exam and the examiner asks what you do when you realize that you have accidentally cut the posterior vagus nerve during a hiatal hernia repair. Is the answer to proceed with a gastric drainage procedure correct? The prevailing dogma seems to be that inadvertent vagotomy will produce gastric stasis/paresis and the stomach will not empty and hence should be accompanied by a gastric drainage procedure. This report presents clinical outcomes of 49 patients who underwent truncal vagotomy without a drainage procedure (pyloroplasty or gastrojejunostomy). METHODS: 49 patients underwent truncal vagotomy with laparoscopic adjustable gastric banding in an IRB (Investigational Review Board)-approved clinical trial to determine if the addition of a vagotomy would increase achieved weight loss when compared to gastric banding alone. The details of this trial were presented at SAGES (Martin and Earle in Surg Endosc 25:2522-2525, 2011) in 2010. The patients in this study have been followed for over ten years and their histories were examined to look for evidence of gastric stasis or intractable diarrhea or if they required further surgery for these complaints. RESULTS: 49 patients have been followed for a mean of 10.9 years. All except one have experienced a loss of hunger and cessation of gastric borborygmus. One patient showed mild delayed gastric emptying after developing diabetes. Two other patients with DM carry a diagnosis of gastroparesis. No patient has experienced intractable diarrhea. Five patients have had revisions to sleeve gastrectomy or gastric bypass for weight loss failure or esophageal dilatation and GERD. CONCLUSIONS: Review of these truncal vagotomy patients without drainage procedures at 10 years does not support the myth that the stomach will not empty after vagotomy and a gastric drainage procedure should always accompany truncal vagotomy.
