[Animal experiments concerning oesophagogastrostomy in oesophageal replacement of the stomach (author's transl)]

Abstract

After resection of the esophagus, the transposition of stomach should be preferred to the interposed colon, because it is technically simpler, can be performed in a shorter time and is only seldom followed by reflux. If the fundus is to be used for the anastomosis with the esophageal stump, a good blood circulation of this gastric part is needed for uncomplicated healing. This is warranted by preserving the right gastric and gastroepiploic arteries, which supply the vascular arcades of the lesser and greater curvature. Additionally to former morphological investigations, the postoperative course after resection of the esophagus and esophagogastrostomies in dogs was studied. In the first animal group only the right gastroepiploic artery, in the second group additionally the right gastric artery were preserved. As result it was found that the vascular arcades along the greater curvature alone are insufficient for the blood supply of the gastric fundus. The findings and their clinical value are discussed.
