Authors discuss the real localion of !he so-called intermuscularabscesses, based on previous descriptionsthey have made of ano-recto-perineal musculature.They point out !he intimate adherence of longitudinalrectum fibers to circular ones, and also describelongitudinal fibers that join fibers froma the levator aniand then descend and form the anal intermuscular septum.Based on anatomical disseclions on fresh cadavericpieces and others kept in formaldeyde, they suggestthat the upper diffusion of suppuralive processes ofcryptic origin is made outside the longitudinal fibers,thus being located between the fascia reclis and thelongitudinal layer, or on the outside between the pelvicfascia and the levator ani

Basados en las descripciones que hemos realizado(comunicaciones previas) sobre la disposición de lamusculatura ano-recto-perineal discutimos la real ubicaciónde los llamados abscesos intermusculares altos.Jerarquizamos el hecho de la íntima adherencia delas fibras longitudinales del recto a las fibras circulares.En ello no difiere del resto de las vísceras digestivas.Asimismo se describen fibras longitudinales unidasa fibras del elevador para descender formando elseptum intermuscular anal.
