Effect of proximal gastric vagotomy on human gastric blood flow evaluated by endoscopic laser doppler flowmetry

The effect of proximal gastric vagotomy (PGV) on gastric blood flow has been evaluated endoscopically by laser Doppler flowmetry (LDF) in 12 patients with duodenal ulcer. The gastric wall circulation was examined at 7 defined positions in all subjects prior to surgery, 1 week postoperatively, and after 3 months. For comparison, 21 healthy volunteers were also examined by LDF.
