[Side effects of proximal selection vagotomy on the esophagus. I. Effects on the esophageal blood circulation (author's transl)].

The influence of the proximal selective vagotomy (PSV) with following skeletisation of parts of the esophagus on its circulation was investigated in an animal experimental study. Among the 6 dogs with PSV and skeletisation of the esophagus up to the upper thorax apertura one was seen with necrosis and perforation in the distal part of the esophagus. The last 5 dogs and the 4 dogs in which after the PSV only the denudation of the distal part of the esophagus was carried out no signs of circulatory disturbance were seen. The blood circulation in human esophagus, as described in the literature, and the transfer of the results from dogs to human is discussed. An enlarged skeletisation of the esophagus in order to improve the completeness of the PSV does not harm blood circulation.
