Anal İnkontinansa Cerrahi Yaklaşım
Özet
Anal inkontinans, fekal materyalin istemsizce sızması olup bireylerin yaşam kalitesini ciddi derecede bozan, utanç duygusu nedeniyle de sağlık merkezlerine başvurunun az olduğu psikososyal bir problemdir. Hastalık; kaçırma formuna göre minör veya majör olarak sınıflandırılırken, etyolojisinde en sık median epizyotomi gibi obstetrik travmalar ve perianal cerrahi geçmişi rol oynar. Detaylı hikaye ve fizik muayene ile başlayan tanı sürecinde; anal sfinkter defektlerinin tespiti için endoanal ultrasonografi (EAUS) en duyarlı yöntemdir; anal manometri ve defekografi de fonksiyonel değerlendirmede kullanılır. Tedavide öncelik, diyet düzenlemeleri, ilaçlar ve biofeedback gibi konservatif yöntemlerdir. Medikal tedaviye yanıt vermeyen durumlarda cerrahi seçenekler devreye girer. Segmental sfinkter defektlerinde en sık sfinkteroplasti uygulansa da uzun dönem başarı oranları zayıftır. Nörojenik vakalarda postanal onarım, ileri hasarlarda ise grasiloplasti, gluteoplasti ve yapay anal sfinkter denense de bu yöntemler yüksek morbidite ve mekanik komplikasyon riski taşır. Buna karşın sakral sinir stimülasyonu, düşük morbidite ve yüksek uzun dönem başarısıyla öne çıkan modern bir seçenektir. Diğer tüm yöntemlerin başarısız olduğu son çare olarak kalıcı kolostomi veya ileostomi gibi fekal diversiyon işlemleri hastaların yaşam konforunu anlamlı ölçüde artırmaktadır.
Anal incontinence is an involuntary leakage of fecal matter that severely impairs patients' quality of life and remains a psychosocial issue with low hospital admission rates due to feelings of shame. The disease is classified as minor or major based on the leakage form, and its etiology is predominantly driven by obstetric traumas such as median episiotomy, as well as histories of perianal surgery. The diagnostic process begins with a detailed history and physical examination, where endoanal ultrasonography (EAUS) is the most sensitive method for detecting anal sphincter defects, while anal manometry and defecography are utilized for functional evaluations. Treatment prioritizes conservative modalities including dietary adjustments, medications, and biofeedback. Surgical options are considered for cases unresponsive to medical treatment. Although sphincteroplasty is most frequently performed for segmental sphincter defects, its long-term success rates are poor. While postanal repair is used in neurogenic cases, and graciloplasty, gluteoplasty, or artificial anal sphincter are attempted in advanced damage, these methods carry high morbidity and mechanical complication risks. Conversely, sacral nerve stimulation stands out as a modern choice with low morbidity and high long-term success. As a last resort when all other methods fail, fecal diversion procedures like permanent colostomy or ileostomy significantly improve patients' life comfort.
