title: [Augmented-pressure colostogram in the radiological assessment of anorectal malformations].
abstract: OBJECTIVE
  To present our experience in detecting the existence of a possible associated fistula between the pouch colon and the urogenital tract in patients with anorectal malformations by carrying out an augmented-pressure colostogram, and its subsequent correlation between radiological and surgical findings.
  
  
  METHODS
  A 17-year retrospective revision of 43 patients with anorectal malformations was performed. 34 of them were referred to the Radiology Department in order to carry out an augmented-pressure distal colostogram prior to surgery.
  
  
  RESULTS
  A fistula was demonstrated in 26 of the 34 patients who had an augmented-pressure distal colostogram done. In the remaining 8 patients, this technique failed to demonstrate a fistula. The radiological findings were confirmed during the surgery in each case.
  
  
  CONCLUSIONS
  The augmented-pressure distal colostogram is a simple and accurate study to delineate the altered anatomy of anorectal malformations, to define the distance between pouch colon and perineum, and to identify the localization of any associated fistulous communication. It is the most dependable test for a surgeon in order to choose the type of surgical approach, which depends on the presence or absence of an associated fistula.
