İnce Bağırsak Kanamaları
Özet
İnce bağırsak kanamaları, tüm gastrointestinal kanamaların %5-10'unu oluşturan, teşhisi ve yönetimi zor, potansiyel olarak ölümcül tablolardır. Yaş gruplarına göre etiyolojisi değişen bu kanamalarda gençlerde inflamatuar bağırsak hastalıkları ve Meckel divertikülü ön plandayken, yaşlılarda anjiyodisplazi ve NSAİİ enteropatisi sık görülür. Vasküler lezyonlar en yaygın nedeni oluşturur. Tanıda kapsül endoskopi, BT/MR enterografi, derin enteroskopi ve sintigrafi gibi yöntemler kullanılır. Tedavide ise hastanın hızlı stabilizasyonu ve multidispliner yaklaşım esastır. Medikal, endoskopik (argon plazma koagülasyon, klip) ve anjiyografik embolizasyon yöntemleri öncelikli olup, tedaviye yanıt vermeyen veya hemodinamik olarak instabil olan hastalarda son çare olarak segmental ince bağırsak rezeksiyonu ve laparoskopik cerrahi teknikler uygulanır.
Small bowel bleedings account for 5-10% of all gastrointestinal bleedings and represent potentially fatal conditions that are challenging to diagnose and manage. The etiology varies by age; inflammatory bowel diseases and Meckel's diverticulum are prominent in young patients, whereas angiodysplasia and NSAID-induced enteropathy are common in older adults. Vascular lesions constitute the most common cause. Diagnosis utilizes methods such as capsule endoscopy, CT/MR enterography, deep enteroscopy, and scintigraphy. Management relies on rapid stabilization and a multidisciplinary approach. Medical, endoscopic (argon plasma coagulation, clipping), and angiographic embolization methods are preferred, while segmental small bowel resection and laparoscopic surgical techniques are applied as a last resort in hemodynamically unstable patients who fail to respond to standard therapies.
