Laparoscopic truncal vagotomy and gastroenterostomy for pyloric stenosis.

BACKGROUND: Gastric outlet obstruction secondary to chronic duodenal ulceration is an indication for surgery as conservative management with balloon dilatation frequently fails. The standard operation is truncal vagotomy and a drainage procedure. However, development of minimally invasive surgery has revolutionized the surgical approach to this clinical problem.

METHODS: Twelve male patients with pyloric stenosis secondary to duodenal ulceration underwent laparoscopic truncal vagotomy and gastrojejunostomy. The perioperative and long term outcome of this group of patients were analyzed.

RESULTS: The median operating time was 210 (range 180 to 240) minutes. Median postoperative stay was 6 (range 4 to 41) days. Conversion to laparotomy was necessary in one patient. Delayed gastric emptying occurred in two patients but resolved on conservative measures. At a median postoperative followup of 6 (range 1 to 12) months all patients had a good symptomatic outcome (Visick grades I or II).

CONCLUSIONS: Laparoscopic truncal vagotomy and gastrojejunostomy is a feasible technique. Intermediate followup shows good symptomatic results when used for pyloric stenosis.
