[Investigation of the healing process of invaginated anastomoses in animal experiments]

The telescopic anastomosis technique is not frequently used method, but its history could have been followed in the surgical literature since the beginning of the XXth century. Authors can use this technique successfully in their clinical practice performing esophago-gastrostomies, esophago-jejunostomies and ileo-colostomies. They would like to show the healing process of these kind of anastomoses in experimental work, using animal subjects, as data regarding this aspect is not found in the literature. The healing process of esophago-gastrostomies, and ileo-colostomies performed on dogs have been examined.

1. The invaginated esophageal or ileal segment (up to 30 mm length of submerged part) has not suffered from ischaemic damage. 2. The invaginated esophageal or ileal segment has been covered by the mucosa of the stomach or colon. 3. The physical strength of the anastomosis has arised gradually based this on the measured bursting pressure values. 4. The quality of the healing process has not depended on the length of the invaginated esophageal or ileal segment (up to 30 mm length of submerged part).
