Role of highly selective vagotomy and duodenoplasty in the treatment of postbulbar duodenal obstruction.

The indications for highly selective vagotomy have expanded in recent years, with the technique being applied to selected cases of perforation and bleeding. Its use in obstruction is controversial, but two options are available for managing the stenotic pylorus or duodenum: dilatation or duodenoplasty. The latter choice requires that the stenosis be located in the postbulbar area. Since 1981, we have managed 15 patients with postbulbar stenosis by means of highly selective vagotomy and duodenoplasty. All patients had a previous history of ulcer disease, and vomiting was a consistent symptom. All patients were referred for surgery, 10 by a gastroenterologist. There was no operative mortality or procedure-related morbidity. Two patients have been lost to follow-up. Both were classified as Visick I and had normal endoscopic results at their last visit. The remaining 13 patients have all been followed very recently. Twelve patients (92%) are currently classified as Visick I or II. One patient (Visick IV), who was essentially asymptomatic, was found to have a recurrent ulcer on endoscopy. Endoscopic (11 patients) or radiographic (1 patient) patency of the duodenoplasty has been demonstrated in 12 patients. Highly selective vagotomy and duodenoplasty should be a surgical consideration when the pathologic anatomy of the duodenum lends itself to that choice.
