Gastroduodenal ulcer treated by pylorus and pyloric vagus-preservinggastrectomy

Figure 1 Schema of PPVPG. I a: Vagus preserved; I b: antral mucosa stripped region; I c: stomach resection region. II a: the antral mucosa 7mm-10mm proximal to the pyloric ring is excised; II b: the distal mucosal edge is sutured round all layers of the cut edge near the greater curvature (stoma for anastomosis); II c: antral seromuscular layer is sutured to the region of anastomosis.

Figure 2 Intestinal content reflux after an intravenous injection of ⁹⁹mTc-EHIDA resulted from different operation modes. A. No reflux resulted from PPVPG; B. Reflux resulted from B I; C. Serious reflux resulted from B II.
