[The effect of selective proximal vagotomy on mucus production of the stomach in pyloroduodenal ulcer].

Secretion of the main component of gastric juice mucus-fucoglycoproteins (FGP) in uncomplicated and complicated by stenosis of gastric outlet ulcer disease of the stomach and intestine, the effect of selective proximal vagotomy (SPV) and drainage operations on FGP exchange were studied. Dependence of fucose production on severity of the course of ulcer disease has been established. Early after SPV, preservation of FGP concentration in the gastric juice at initial level and significant decrease in their hour production were noted. FGP concentration in patients with its low initial values restored within the first year of follow-up, debit--later on. The data obtained can be used in assessment of the SPV results, and in revealing the patients with high risk for development of ulcer disease recurrence.
