Anismus
Özet
Anismus, dışkılama sırasında pelvik taban kaslarının (özellikle puborektal kas ve eksternal anal sfinkter) uygunsuz kasılması veya gevşeyememesiyle karakterize fonksiyonel bir boşaltım bozukluğudur. Etiyolojisi tam olarak bilinmemekle birlikte, sıklıkla genç ve orta yaşlı kadınlarda görülür; düşük lifli diyet, psikolojik travmalar ve cinsel istismar öyküsü gibi faktörlerin hastalıkla ilişkili olduğu düşünülmektedir. Temel semptomlar arasında kronik kabızlık, aşırı ıkınma, tam boşalamama hissi ve dijital yardım gereksinimi yer alır. Tanı koymak için tek başına fizik muayene yeterli değildir; anal manometri, balon atma testi, defekografi ve EMG gibi fizyolojik testlerin birlikte değerlendirilmesi gerekir. Tedavi sürecinde ilk basamak yaklaşımı; lifli diyet, probiyotikler ve özellikle pelvik koordinasyonu yeniden kazandırmayı hedefleyen biofeedback terapisidir. Biofeedback'in yetersiz kaldığı durumlarda botulinum toksin enjeksiyonları denenebilirken; inkontinans riski ve düşük başarı oranları nedeniyle cerrahi müdahaleler günümüzde öncelikli olarak tercih edilmemektedir.
Anismus is a functional evacuation disorder characterized by the inappropriate contraction or failure to relax of the pelvic floor muscles, particularly the puborectalis muscle and external anal sphincter, during defecation. Although its etiology is not fully understood, it is most commonly observed in young and middle-aged women, with factors such as a low-fiber diet, psychological trauma, and a history of sexual abuse thought to be associated with the condition. Core symptoms include chronic constipation, excessive straining, a feeling of incomplete evacuation, and the need for digital assistance. Physical examination alone is insufficient for diagnosis; therefore, a combination of physiological tests such as anal manometry, balloon expulsion test, defecography, and EMG must be evaluated. The primary treatment approach involves dietary modifications with fiber, probiotics, and especially biofeedback therapy, which aims to restore pelvic coordination. In cases where biofeedback is insufficient, botulinum toxin injections may be considered, whereas surgical interventions are currently not preferred as a primary option due to the risk of incontinence and low long-term success rates.
