[Diagnosis and treatment of ectopy of the anal canal]

An analysis of findings of clinical and ++roentgenological examinations of 55 patients with ectopy of the anal canal prior to operation and 68 patients after correction of the defect has shown that secondary megacolon developed in proportion with the age and degree of the outlet opening stenosis and there appeared injuries of elements of the normally formed anal canal. The authors described their original many-steps operation of the formation of the anus which allows all elements of retaining feces to be preserved. The amount of good long-term results increased from 22-26% up to 75% as compared with those of operations after Stone.
