[Unusual anorectal anomalies. A clinical contribution]. / Anomalie anorettali rare. Contributo clinico.

Anorectal malformations (ARM) include a spectrum of anomalies which have been subdivided as "high", "intermediate" and "low"; a fourth group, defined as "miscellaneous", collects the forms which are most rarely observed. It is important, for a specialist, to know the last ones under the diagnostic and/or therapeutic profile. In this paper, the various problems observed in five cases of ARM considered particularly rare are analysed: a case of anorectal agenesia with recto-cloacal fistula and short uro-genital sinus; a rectal atresia with normal anal canal; a case of anorectal stenosis; an incomplete anal membrane; an anal agenesia with scrotal fistula.

[Rare anorectal malformations. Intermediate-type anal agenesis with a rectocutaneous fistula]. / Malformazioni anorettali rare. L'agenesia anale di tipo intermedio con fistola retto-cutanea.

A case of anal agenesia with recto-cutaneous fistula is presented. The recto-cutaneous fistula in an intermediate or high anomaly seldom noticed so that it is not included in the common classifications. The surgical approach performed by us was that described by Mollard. The anterior perineal pull-through, under proximal protective enterostomy, allow to reduce the rate of postoperative complications and sequences and obtain--as in our patient--a normal continence and sphincteric function with an excellent esthetic outcome.
