[Millard's flap for sequelae of high anorectal malformations. Apropos of 6 cases].

Mucosal prolapse is a frequent sequela after surgical treatment of the high type of anorectal malformation whatever was the technic used for the pull-through operation. The authors report six cases treated with the spiral flap described by Millard. The initial procedures had been a Romualdi-Rehbein pull through in three cases with secondary revision of anoplasty and a Stephan's operation in the three other cases. Before Millard's plasty, all the patients were continent and two of them had an associated stricture. The anatomical result was good in all the cases with reconstruction of a cutaneous anal funnel and no stricture. Improvement of continence was noted in two cases, uncertain in two. Incontinence remained unchanged in two other cases. The advantages of the Millard's plasty are analysed. The prevention of mucosal prolapse is possible in the initial pull through operation using the same plasty or whatever plasty which provides a cutaneous anal canal.
