RESUMEN
OBJECTIVES: Objective of the study was to examine patients with fistula preoperatively with MRI and then compare with operative findings. BACKGROUND: Most common cause of perianal suppuration is infection of cryptoglandular origin. This results in simple intersphincteric abscess, or spreading of infection in cranial or caudal direction, horizontally or circulary. To choose the correct surgical therapy, sufficient diagnostic is necessary. This includes clinical examination, endorectal ultrasonography, rectoscopy with fistula injection with hydrogen peroxide or dye. More and more often MRI is used. METHODS: In 2007 19 patients with perianal fistula were operated on. In 14 patients, preoperative MRI was done without contrast dye or probing. Fistulas were classified on 5-grade scale. We treated simple fistulas with fistulectomies, in three cases of complicated fistulas cutting setons were used. RESULTS: We examined 14 patients and confronted preoperative MRI result with operative findings. In 12 patients results matched, in two patients peroperatively diagnosed and treated fistula did not show on MRI. One was transsphincteric fistula with abscess and one was simple transsphincteric fistula.Because of low number of patients, statistical interpretations are not significant. CONCLUSIONS: Results are preliminary, we continue in prospective analysis. MRI may be useful for successful treatment by correct assessment of the extent of disease. It is necessary to consider cost-effectiveness when indicating MRI (Tab. 6, Fig. 3, Ref. 11). Full Text (Free, PDF) www.bmj.sk.

Since beginning, NMR examination is fully established in experimental work and common clinical praxis. Its extensive use in cardiology is determined by non-invasive character and relatively short examination time. After solving predominately economical problems, NMR examination will rapidly develop even in Slovak Republic (Tab. 2, Fig. 2, Ref. 29).
