[The long-term evaluation of artificial myoplastic anus and artificial classical anus based on manometric and...

The aim of this study was comparative evaluation of the pressure profile in the artificial myoplastic anus and the one created by the use of classical method. Radiological examinations of the colon by the use of the contrasting agent were performed in all patients in each group. In the group of patients with artificial myoplastic anus radiological examinations showed the narrowing of the lumen 4-7 cm in length in all patients. Above the narrowing the widening of the lumen was present. Reflexive flow of the contrasting agent from the colon was not present. In the group of patients with the artificial classical anus the narrowing of the terminal part of the colon was not noticed in the radiological examination. In all patients the reverse flow of the contrasting agent through the artificial anus was observed. Patients with the artificial myoplastic anus created by the use of pedunculated fold of the muscular coat of the colon have much higher average pressures around the myoplastic sphincter than in the presphincteric area, while the patients with the artificial classical anus did not present the area with the increased pressure in the terminal part of the colon. The possibility of preventing uncontrolled defecation and flatulence by the patients with the artificial myoplastic anus is related to the repeatedly higher pressures around the sphincter than in the presphincteric area, which do not decrease as the time passes by after the surgery.
