Proximal selective vagotomy (PSV) is an effective, definitive therapy for peptic ulcer disease of the duodenum. Long-term studies have shown that ulcer recurrence occurs in less than 10% of patients if the operation is performed by an experienced surgeon. Since PSV does not influence gastric emptying, side effects such as diarrhea, gastric stasis or the dumping syndrome are rare. Due to this favorable experience, PSV is our preferred technique for the laparoscopic approach to peptic ulcer disease. We have performed this operation in 13 patients. Indications were chronic duodenal ulceration unresponsive to medical therapy, chronic duodenal ulceration combined with reflux esophagitis, and reflux esophagitis due to gastric acid hypersecretion. In patients with reflux esophagitis PSV was performed in addition to an antireflux procedure. Laparoscopic PSV can be performed more accurately than the open procedure since it allows for better visualization with less possibility of missing small vagal connections to the parietal cells such as the 'criminal nerve'. The median duration of operation was 3 hours. There were no serious peri- or postoperative complications. The median time of postoperative hospital stay was 3 days. During the median follow-up of 27 months no recurrence of duodenal or esophageal ulceration was encountered and none of the patients complained of epigastric pain, diarrhea or dumping symptoms.
