| Abscess and fistula in the anorectal region can readily be a source for inectious spread to the adjacentcompartments around the anorectal junction which is interconnected from muscularis propria of the rectal wall tothe internal sphincter of the anal canal. Prompt and yet accurate diagnosis will lead to optimal surgicalmanagement of the parient. To evaluate the diagnostic value of endorectal sonography, we reviewed operativelyconfirmed 18 cases of anorectal abscess with or without fistulae in 14 patients. Abscesses were classified intothe 5 types according to the location : ischiorectal, perianal, intersphincteric, supralevator and submucous(intermuscular) type. The most frequent type was ischiorectal in 10 cases (55.6%). Perianal type was seen in 3cases (16.6%), intersphincteric in 2 cases (11.1%), supralevator in 2 cases (11.1%) and submucous type in 1 case(5.6%). The most frequent direction of the abscess spread was to the posterior aspect of the rectum in 9 cases(50%). Horseshoe shape abscess was present in 2 cases. Fistulae were classified into 4 types according to therelationship of the tracks to the internal and external sphincter ; tanssphincteric, intersphincteric,suprasphincteric, and extrasphincteric. Fistulous tracks wee associated in 12 of 14 patients and the most commonfeature was transphincteric type in 8 cases (66.7%) In conclusion the endorectal sonography is a useful method inevaluation of location, extent and detection a fistula in anorectal abscess. |
