Gastroduodenal ulcer treated by pylorus and pyloric vagus-preserving gastrectomy.

AIM:To evaluate the curative effect of pylorus and pyloric vagus-preserving gastrectomy (PPVPG) on peptic ulcer.METHODS:Treating 132 cases of GU and DU with PPVPG, and comparative studies made with 24 cases treated with Billroth II (B II ) and 20 cases with Billroth I(BI); advantages and shortcomings evaluated.RESULTS:Not a single death after PPVPG. No recurrence of the disorder in the subsequent follow-up for an average of 6.5 years. Curative effect (visik II & I) 97.7%. Acidity reduction similar to that found in B II and BI, but 97.7% of the B II and all BIcases having more than second degree intestinal fluid reflux, in contrast to 7.1% in PPVPG cases. Dumping syndrome occurred in the B II and BI cases, none in PPVPG cases. With regard to gastric emptying, food digestion, absorption, body weight and life quality, PPVPG proved to be superior to Billroth procedure.CONCLUSION:PPVPG has the advantages of conventional Billroth gastrectomy in reducing acid, removing ulcer focus, and at the same time preserves the pylorus and pyloric vagus for maintaining the normal gastric physiological function.Dumping syndrome,intestinal fluid reflux and other complications of conventional gastrectomy may be avoided.
