Anal Apse
Özet
Anal apseler ve fistüller, akut inflamatuar süreçler ile kronik evreler arasında geçiş gösteren, birbiriyle yakından ilişkili anorektal hastalıklardır. Toplumda görülme sıklığı her 100.000 kişide 8.6 ila 20 arasında değişen bu durum, özellikle 40 yaş civarındaki erkeklerde daha yaygındır. Hastalığın temelinde anal kriptlerin tıkanmasıyla açıklanan kriptoglandüler teori yatmaktadır. Anal apseler anatomik yerleşimlerine göre perianal, iskiorektal, intersfinkterik, supralevator ve submüköz olarak beş sınıfa ayrılır; bunlardan en sık perianal ve iskiorektal tiplere rastlanır. Hastalar genellikle şiddetli ağrı, ateş ve şişlik şikayetleriyle başvururken, tanıda fizik muayene ve gerektiğinde MRG veya BT gibi görüntüleme yöntemleri kritik rol oynar. Tedavinin temel taşı acil cerrahi drenaj olup, apse levator ani kasının seviyesine göre iç veya dış yolla drene edilir. Antibiyotik kullanımı ise yalnızca immün yetmezliği olan veya selüliti bulunan hastalarda cerrahiye ek olarak tercih edilir. Cerrahi sonrası nüks oranı yaklaşık %13 civarındayken, yetersiz drenaj en önemli başarısızlık nedenidir. Tedavi edilmeyen veya yanlış yönetilen apseler, %50'ye varan oranlarda kronik anal fistüllere dönüşerek ciddi morbidite ve maliyet artışına sebep olabilir.
Anal abscesses and fistulas are closely interrelated anorectal diseases representing different stages of a shared pathological process, where acute inflammation often leads to chronic fistula formation. With an incidence of 8.6 to 20 per 100,000 people, the condition predominantly affects males around age 40 and is primarily explained by the cryptoglandular theory involving the obstruction of anal crypts. These abscesses are categorized into five types based on their anatomical location—perianal, ischiorectal, intersphincteric, supralevator, and submucosal—with perianal and ischiorectal types being the most common. Patients typically present with severe localized pain, fever, and swelling, necessitating a diagnosis based on physical examination and, in complex cases, advanced imaging like MRI or CT scans. The cornerstone of treatment is surgical drainage, performed either externally or internally depending on the abscess's relation to the levator ani muscle, while antibiotics are reserved for immunocompromised patients or those with concomitant cellulitis. Postoperative recurrence rates average around 13%, often due to inadequate drainage, and improperly managed cases can lead to chronic fistulas in up to 50% of patients, causing significant morbidity and increased healthcare costs.
