Comparative study of transverse and oblique partial resection of esophagus in dog

Abstract EN

This study has been done to evaluate the effect of transverse and oblique anastomosis on esophageal healing.

Partial esophagectomy were performed on sixteen adult dogs, animals were divided into two equal groups ,in the group one a transverse anastomosis, while in group two oblique anastomosis were done .

Two layers of simple interrupted pattern were used to closed the anastomosis site, the first layer was oppose the mucosa and submucosa by simple interrupted suture with the knots tided inside the lumen and the second layer was appose muscularis and adventitia by simple interrupted suture using catgut (2.0).

The results of histopathological and radiological were revealed that ,the healing of group two was faster than group one, which manifested by collagen fiber formation with complete mucosal formation in a shorter time compared with group one .

In addition to that the mean degree of stenosis was less in second group at 30 days post operation (14.24 ± 0.21), in spite of no significance difference between two groups at the level of p ≤ 0.05.
