Diagnostics and Treatment of Fistula Forms of Rare Regional Variants of Anorectal Malformations in Children

Aim: The aim of the study was to study the frequency of nosological forms, features of clinical and anatomical variations, the nature of combined anomalies and the choice of diagnostic and treatment methods for fistulous forms of rare regional variants of ARM in children.

Materials and Research Methods: In the clinical bases of the Department of Hospital Pediatric Surgery of TashPMI in 2009 - 2019, 504 children with ARM were examined and treated. At the diagnostic stage, clinical and laboratory, instrumental and special research methods.

Results: In our observation, 121 children had rare regional variants of anorectal malformations. These forms accounted for 24.1% in the general structure of ARM with fluctuations from 0.83% to 24% among various nosological forms; prevailed among girls - 95 (78.5%), among boys - 26 (21.5%). Ectopia of the anus was observed in 25.6% of cases; H-form rectogenital fistulas with a normally formed anus in 24%; atresia with rectovaginal fistula in 18.2%. Cases of rectal duplication, exstrophy of the cloaca, and urogenital fistula are presented. The nature and frequency of concomitant pathology in various nosological forms have been analyzed.
