Persistent dysphagia after laparoscopic vagotomy

Laparoscopic vagotomy represents a new and less invasive treatment for peptic ulcer disease, but the problem of postvagotomy dysphagia has not been solved. The aim of this study was to determine the etiologic factors related to long-term laparoscopic postvagotomy dysphagia.

Two female and 11 male patients with a mean age of 48.5 years who underwent laparoscopic vagotomy were investigated retrospectively. Preoperative diagnosis included duodenal ulcer resistant to medical treatment, gastric hypersecretion, gastric outlet obstruction, cholelithiasis, and gastroesophageal reflux disease (GERD). Ten patients underwent laparoscopic highly selective vagotomy, and three patients had laparoscopic truncal vagotomy with gastrojejunostomy or pyloroplasty. Nine of these patients had a Nissen fundoplication in conjunction with the vagotomy.

The median long-term follow-up period was 47 months. Two patients complained of severe dysphagia, one of moderate dysphagia, and two of mild dysphagia. Neither type of vagotomy nor an additional fundoplication was correlated with the severity of postoperative long-term dysphagia. Severity of postoperative dysphagia was associated with severity of preoperative dysphagia (r = 0.752, p = 0.003) but not with heartburn (r = 0.358, p = 0.531) or regurgitation (r = 0.024, p = 0.938). The cause of preoperative dysphagia varied; however, all of these patients had GERD and consequent esophageal lesions.

Preexisting dysphagia appears to play an integral role in persistent postoperative dysphagia. Care must be taken to construct a loose fundoplication in patients with dysphagia.
