[Pseudocontinent colostomy - comparative experimental study].
The possibilities of smoothmuscle sphincteroplastic have been researched experimentally at 29 mongrel dogs. Six types smoothmuscle plastics have been studied--a method of Feodorov and Odariuc, a method of Musiani, a pylor as a sphincter, an own operative method in three versions. A comparatively research upon a functional fitness of the offered plastics and Schmidt's method has been done. The level of intraluminal pressure into the precolostomy segment of colon and a functional status of the taken out colostomy have been compared. The reliable lower level of intraluminal compression has been established (p < 0.05), using longitudinal muscle as a plastic material. The intraluminal pressure into the end segment of colon has been sustained raised, permanently, due to the tonus of circular muscle in to the transplant's wall. The degree of intraluminal compression seems to be directly proportional to the volume of stretching of smoothmuscle transplant (p < 0.001). There has been done a conclusion, that the smoothmuscle plastic gives operative-technical possibilities for raising of intraluminal pressure by changing the volume of stretching of the transplant.
