ABSTRACT
Classification of a sigmoidocele according to Jorge et al. ( 7 ) is based on the images obtained at defecography. This classification takes into account the lowest part of the sigmoidocele. Grade I sigmoidoceles have their deepest end above the pubococcygeal line. Grade II are below this line but above the ischiococcygeal line, and grade III sigmoidoceles descend beyond the ischiococcygeal line.
