Anterior or posterior gastro-jejunostomy with truncal vagotomy for duodenal ulcer--are they functionally different?

Truncal vagotomy with gastrojejunostomy (GJ) is the standard treatment for chronic cicatrizing duodenal ulcer with gastric outlet obstruction. We tried to determine if a significant functional difference exists in the early and late outcomes following anterior and posterior types of GJ to treat this condition. The case records of 106 patients who underwent truncal vagotomy and GJ at our institute from 1 January 1995 to 31 December 1999 were studied retrospectively.
