Colonic anastomosis in calves: an experimental study.
Colonic anastomosis was conducted in 12 calves divided equally into four groups. Four suture patterns, viz. single inversion (continuous Connell), double inversion (two rows of continuous Cushing), single eversion (continuous everted mattress), double eversion (single eversion reinforced with simple continuous) were used. In each animal, anastomosis of the same technique was performed at four places. Each technique was evaluated in terms of clinical and gross observations, lumen stenosis and bursting pressure. Observations were made on the 7th, 14th and 28th day after anastomosis. None of the anastomotic techniques showed any untoward incident during the 28 days of postoperative study. Stricture formation at the site of anastomosis was minimal with the single inversion technique whereas it was maximum with the single eversion technique. Pressure for disruption of intestinal segments was higher after inversion than eversion techniques. It was concluded that the one-layer inversion anastomosis technique proved to be the best among the four techniques because (i) of its reduced incidence of adhesions; (ii) it maintains adequate lumen diameter; (iii) it withstands maximum pressure. The double layer inversion technique was conceded to be the second best choice for colonic anastomosis followed by the double eversion and single eversion techniques.
