Suture of the diaphragmatic esophageal hiatus (an experimental study).

Eighty rabbits were submitted to different procedures on the esophageal hiatus of the diaphragm. The authors concluded that section of the peritoneal lining, removal of the perimysium of the crura of the medial diaphragmatic limb and abrasion of its borders, do not cause local adhesions. On the other hand, the approximation of these muscular structures with interrupted nylon sutures, determines the formation of the scar uniting them. The resistance of the scar varies in different animals but the average values recorded, showed the efficiency of the suture used.
