EXPERil\1ENTAL STUDIES OF END-TO-END EVERTING AND INVAGINATING INTESTINAL ANASTOMOSES IN GOATS

Abstract

Six clinically health Borno white goats weighing 20-30 kg and aged 1.5-2 years were used in this : study. Two sites on the intestine 10 em apart in each goat were chosen. The healing patterns of two techniques, the cnd-ro-end single layer everting and end-to-end single layer invaginating techniques of expcrimem<:ll intestinal ileal anastomoses were compared. Post operative clinical course in the goats. gross and microscopic appearance of anastomotic sites were studied at various time intervals to determine the h�aling quality. The clinical course was associated with post operative complications which in some goats ended fatally. Grossly. the inverted anastomosed sites showed extensive adhesion formation. leakage on clay 3 biopsy samples in one goat and intestinal lumen obstruction in another. There was also persistem int1ammatory reaction. The invaginated segment showed lesser degree of swelling and fibrin deposition. Microscopically, biopsy samples revealed non-union of the intestine at day 3 post surgery in both techniques. On day 15, adequate union of intestines was observed for the invagination technique. In the everting technique there was persistence of int1ammatory cells. Healing was faster in invaginating than everting intestinal anastomosed sites. The invaginating intestinal anastomoses appears to be a beaer technique than everting intestinal anastomosis in goats.
