This study evaluates how efficiency Colo colonic anastomosis with invagination is and compare them to anastomosis done by only one continuously suture. There were analyzed 40 healthy animals (canis familiares) male and female. They weight from about 7,9 to 17 kg and they were from Prefeitura Municipal de Teresina Kennel, Piauí. They were divided into 2 groups of 20 animals: Group I (control) –These ones were done colo colonic anastomosis by manual continued suture. Group II (study) –These ones were done anastomosis with invagination into the lumen of the proximal segment and the distal segment with four fixing points, and both anastomosis performed by polypropylene. All the animals in both groups after having mechanical preparation of the colon, they passed through laparotomy with section of descending colon and anastomosis. They all have been fully observed by veterinarians in pre and postoperatively surgery. They were fed with standard dog food and water, ad libitum when their first bowel movement occurred. These animals were euthanized on 21st day postoperatively after application of potassium chloride intravenously to 20%, a new laparotomy was done and it was performed an evaluation of colo colonic anastomosis. It was measured the level intestinal adhesions and the breaking pressure of the anastomosis. It was applied Fisher’s test to evaluate the parity between the sex and the complications from both groups. The test t de Student unpaired to their weights and levels of adherence according to Zuhlke’s group classification. There was one death (4,5%) in group I and two deaths (9%) in group II. The one from group I (control) died on 7th day postoperatively due to dehiscence of the abdominal wall. From group II (study) one of them died on 6th postoperatively due to dehiscence of the anastomosis and the other one on 10th due to dehiscence of abdominal wall. There were no significant differences in the level of intestinal adhesions among groups. While performing the bursting pressure tests, there was no anastomosis rupture in any animals from both groups (p>0,05). It was concluded that colo colonic anastomosis with invagination is as safe and effective as anastomosis with manual continuously suture.
