Radiological evaluation of anal fistulae: a prospective study of fistulograms.
A review of 33 fistulograms in a four-year study is presented. Four types of communicating tracts have emerged: single (58%), branched (18%), fistulous abscess (15%) and compound (9%). This classification has formed the basis of selection of operative treatment in all the cases. Diminished lumbo-sacral angle was also found in most of the anal fistula cases and this establishes a possible association between the pathology of anal fistula and the low back syndrome.
