| Abstract | ||
| This aim of this study was to evaluate the complications and final function outcome of wrapping nonvascularized omentum graft around the suture line of esophageal anastomosis. Twelve adult local breed dogs were used in this study. The animals were divided into two equal groups (control and treated), all animal induced into general anesthesia by injection of atropen sulphate in a dose 0.04 mg/kg B.W, intramuscularly then after 15 minute given mixture of ketamine hydrochloride and xylazine hydrochloride in doses 15 mg/kg and 5 mg/kg B.W intramuscularly respectively. An oblique resection of about 1cm of the esophageal length and anastomosis by double layer of simple interrupted pattern by 2.0 cat gut suture (control group), same procedure was done in treated group except the wrapping the anastomosis site with patch of omentum tissue after lapratomy operation in the left flank region procedure. The clinical signs of treated animal revealed signs of dysphagia and regurgitation in treated group while this signs disappear in the control group. Radiological and histopathological examination of the anastomosis site performed at 15 and 30 days post operation. Radiological study recorded high degree of stenosis in the anastomosis site in treated group at 15 and 30 days post operation in compared with animals in control group that record mean degree of stenosis in treated group at 15 day (57.61±0.2) and at 30 day (55.78±0.2) while it recorded in control group at 15 day (39.34±1.04) and at 30 day (36.0.6 ±0.9), histopathological results recorded enhanced healing of anastomosis site in treated animals more than control animals. In conclusion we found that non vascularized omental graft prevent leak when used around the anastomosis line in esophageal and enhanced healing of anastomosis line but it increase the stenosis, fibrosis and adhesion of anastomosis site with surrounding muscle and this interferes with the swallowing as well as dysphagia and regurgitation. | ||
