Özet
Amaç: Manyetik rezonans görüntüleme (MRG) perianal bölgenin değerlendirilmesinde yüksek güvenilirliğe sahip non-invaziv bir yöntemdir. Bu çalışmada, perianal fistül tanısı alan hastaların preoperatif MRG bulguları ve özellikle sınıflandırmanın görüntülerle birlikte sunulması amaçlandı. Yöntemler: Perianal fistül tanısı alan 57 hastanın demografik özellikleri ve kontrastlı konvansiyonel ve difüzyon MRG bulguları retrospektif olarak değerlendirildi. Perianal fistül sınıflandırılması MRG bulgularını temel alan 'St James Üniversite Hastanesi (SJUH) Sınıflaması' referans alınarak yapıldı. Bulgular: Çalışmaya 57 hasta (44 erkek ve 13 kadın: yaş aralığı 18-72 yıl; ortalama yaş 45,7 yıl) dahil edildi. Hastaların büyük çoğunluğunun esas yakınması makatta ağrı ve akıntı idi. Bazı hastalar ek olarak makatta kaşıntı, şişlik ve kızarıklık semptomları da bildirdi. 37 hastada tip 1, dokuz hastada tip 2, dört hastada tip 3, beş hastada tip 4, iki hastada ise tip 5 fistül saptandı. Anal kanala açılım yerleri 21 hastada saat 6, 10 hastada saat 7 olarak saptandı. Konvansiyonel ve difüzyon MRG ile fistül traktı, apse varlığı, rektuma açılım yeri, sfinkterle veya komşu anatomik yapılarla ilişkisi tüm hastalarda net olarak değerlendirildi. Sonuç: Anal kanal ve perine derisi arasında meydana gelen anormal bağlantı perianal fistül olarak adlandırılmaktadır. Genellikle tekrarlayan anorektal apselerin komplikasyonudur. Crohn, tüberküloz, malignite gibi inflamatuar süreçlere sekonder de gelişebilir. Tedavide esas yöntem cerrahidir. Cerrahi yetersizliğine bağlı rekürrens oldukça sıktır. MRG bulgularının iyi bilinmesi ve cerrahın iyi yönlendirilmesi ile rekürrens oranı en aza indirgenebilmektedir.
Aim: Magnetic resonance imaging (MRI) is a non-invasive and high reliability procedure for evaluation of perianal area. In this study, our purpose is to present preoperative MRI findings and classification with images in diagnosed perianal fistula patients. Methods: Contrast enhanced (CE) conventional MRI images, diffusion weighted MRI images and demographics of 57 patients were retrospectively evaluated. Perianal fistula classification is based on St James University Hospital (SJUH) classification system. Results: 57 patients (44 men and 13 women, average of 18 to 72 years, average age of 45.7 year) were included in this study. Most of the patients had symptoms of rectal pain and discharge. Some patients had additional complaints like rectal itching, swelling and erythema. 37 patients had grade 1, nine patients had grade 2, four patients had grade 3, five patients had grade 4 and two patients had grade 5 fistula. Fistula opening positions into anal canal were 6 o'clock in 21 patients, 7 o'clock in 10 patients. Fistula tract, its opening position into anal canal, presence of abscess and its relationship with sphincters or neighboring anatomical structures were clearly appreciated with conventional and diffusion weighted MRI in all patients. Conclusion: Perianal fistula is the abnormal connection between anal canal and perinea. It is usually a complication of anorectal abscess. It could occur secondary to inflammatory processes like Crohn's disease, tuberculosis or malignancy. Surgery is considered as the primary treatment. Recurrence due to surgical inadequacy is common. Recurrence rates could be minimized with a good knowledge of MRI findings and well informing the surgeon.
