Experimental colonic anastomosis in bovines--and angiographic study.
4 different methods of colonic anastomosis, single and double layer inversion and eversion, were performed on cowcalves. Hypervascularization of neovascularized arterioles at the cut ends of colon were visualized on the 7th day by all techniques. The arterioles, later one, tended to reorganise towards normalcy. Inversion technique showed better vascularization at the anastomotic site, and the vascular pattern was nearly normal on the 14th and 28th days from surgery. Eversion technique did not exhibit satisfactory revascularization of the anastomotic site on the 7th day of study. A radiopaque area, davoid of arterioles, was noted on the 14th and 28th days from surgery.
