Evaluation comparing colo-colonic anastomosis by manual continued suture with colo-colonic invagination: experimental dogs studies / AvaliaÃÃo comparativa entre anastomoses colo-colicas com sutura manual contÃnua e invaginaÃÃo colo-cÃlica: estudo experimental em cÃes

CoordenaÃÃo de AperfeÃoamento de Pessoal de NÃvel Superior / 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, PiauÃ. They were divided into 2 groups of 20 animals: Group I (control) âThese ones were done colo colonic anastomosis by manual continued suture. Group II (study) âThese 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 Fisherâs 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 Zuhlkeâs 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. / Esse estudo avaliou a eficÃcia das anastomoses colo-cÃlicas com invaginaÃÃo comparando com anastomoses realizadas com sutura Ãnica e contÃnua. Foram utilizados 40 animais (Canis familiares) machos e fÃmeas, pesando entre 7,9 a 17 Kg, clinicamente sadios, oriundos do Canil da Prefeitura Municipal de Teresina, PiauÃ. Foram distribuÃdos em 2 grupos de 20 animais: grupo I (controle) â animais submetidos a anastomose colo-cÃlicas com sutura manual contÃnua em plano Ãnico e grupo II (estudo) â animais submetidos a anastomose com invaginaÃÃo do segmento proximal no lÃmen do segmento distal e fixaÃÃo com quatro pontos, sendo ambas anastomoses realizadas com fio de polipropileno. Todos os animais de ambos os grupos foram submetidos à laparotomia com secÃÃo do cÃlon descendente e anastomose, apÃs preparo mecÃnico dos cÃlons e acompanhados no trans e pÃs-operatÃrio por um mÃdico veterinÃrio. Foi instituÃda alimentaÃÃo a base de raÃÃo padrÃo e Ãgua, ad libitum quando ocorreu a primeira evacuaÃÃo. Esses animais foram submetidos à eutanÃsia no 21 dia de pÃs-operatÃrio apÃs aplicaÃÃo de cloreto de potÃssio a 20% endovenoso; realizou-se nova laparotomia e avaliaÃÃo da anastomose colo-cÃlica. Avaliou-se o grau de aderÃncias intestinais e a pressÃo de ruptura das anastomoses. Foi aplicado o teste de Fisher para avaliar a paridade entre os sexos dos exemplares e as complicaÃÃes entre os dois grupos. E o test t de Student nÃo pareado para os pesos dos animais e os graus de aderÃncia de acordo com a classificaÃÃo de Zuhlke dos grupos entre si. Ocorreu um (4,5%) Ãbito no grupo I e dois (9%) no grupo II sendo o do grupo I (controle) no 7 dia pÃs-operatÃrio devido à deiscÃncia da parede abdominal e os do grupo II (estudo) no 6  e 10 dia de pÃs-operatÃrio devido à deiscÃncia da anastomose e da parede abdominal, respectivamente. NÃo foi observado diferenÃa estatÃsticamente significante no grau de aderÃncias intestinais entre os grupos. Durante a realizaÃÃo do teste de pressÃo de ruptura, nÃo ocorreu ruptura das anastomoses em nenhum dos animais de ambos os grupos (p>0,05). A anastomose colo-cÃlica com invaginaÃÃo apresentou a mesma seguranÃa e eficÃcia da anastomose realizada com sutura manual contÃnua em plano Ãnico.
