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 com parative studies made with 24 cases treated with Billroth I (B I) and 20 cases with Billroth II (B II); 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 I-&-II) 97.7%. Acidity reduction similar to that found in B I and B II, but 97.7% of the B I and all B II cases having more than second degree intestinal fluid reflux, in contrast to 7.1% in PPVPG cases. Dumping syndrome occurred in the B I and B II 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.
