Experimental study of pylorus and pyloric vagus preserving gastrectomy.

In an attempt to prevent the sequelae of conventional gastrectomy, such as rapid gastric emptying, dumping syndrome, intestinal content reflux, indigestion, and poor absorption, we have devised the pylorus and pyloric vagus preserving gastrectomy (PPVPG). Experimenting on 48 dogs, we found theoretic grounds for using our design and obtained the desired effects--retaining the merits of conventional subtotal resection of the stomach, with acidity reduction, while avoiding the above-mentioned complications.
