STRUCTURE OF THE ANAL CANAL AND ANAL SPHINCTER DOGS IN NORM AND AFTER PROCTECTOMY WITH BRINGING DOWN THE COLON

With gistostereometry study the structure of the anal canal and anal sphincter dogs in norm and after proctectomy with bringing down the colon, forming neoanus and neosphinkter. The artificial sphincter is the inevitable process of smooth muscle atrophy can save at least half the volume of smooth muscle, similar to the number in the internal sphincter needed to restore function after holding involuntary proctectomy. Neoanus of mucous and submucosal colon relegated acquired typical smooth relief with the advent of the vertical pleats on the type of anal columns of Morgagni and with the perianal skin was closely associated with the subcutaneous portion of the external sphincter smooth muscle and an artificial sphincter. Thus, the experimental model of the internal sphincter and neoanus created by bringing down the mucous and the formation of smooth cuffs, very similar in quantitative and qualitative terms, the structure of the anal canal and anal sphincter dogs and can be used in clinical practice.
