İleus
Özet
İleus, bağırsak içeriğinin mekanik veya paralitik nedenlerle ilerleyememesi olarak tanımlanan ve akut karın ağrısının başlıca nedenlerinden olan kritik bir cerrahi tablodur. Mekanik ileusun en yaygın sebebi geçirilmiş cerrahi sonrası oluşan adezyonlar iken, bunu tümörler ve fıtıklar takip eder; vakaların %80'i ince bağırsak kaynaklıdır. Paralitik ileus ise fiziksel bir engel olmaksızın bağırsak hareketlerinin durmasıdır ve genellikle postoperatif dönemde ya da elektrolit bozuklukları gibi nedenlerle görülür. Hastalığın klinik belirtileri arasında karın ağrısı, kramplar, şişkinlik ve kusma yer alır; özellikle strangülasyon (boğulma) veya nekroz şüphesi olan durumlarda acil cerrahi müdahale hayati önem taşır. Tanı sürecinde fizik muayenenin yanı sıra direkt batın grafisi ve altın standart olarak kabul edilen bilgisayarlı tomografi (BT) kritik rol oynar. Tedavi yaklaşımı, sıvı-elektrolit desteği ve nazogastrik tüp ile dekompresyon gibi konservatif yöntemlerle başlasa da, tam tıkanıklık ve iskemi bulguları olan olgularda cerrahi tedavi kaçınılmazdır. Postoperatif süreçte bağırsak motilitesinin geri dönmesi için ilaç tedavileri de kullanılabilirken, tanı konulmamış vakaların tümör açısından titizlikle değerlendirilmesi gerekmektedir.
Ileus is a critical surgical condition defined as the failure of intestinal contents to progress due to mechanical or paralytic reasons, and it is a leading cause of acute abdominal pain. While the most common cause of mechanical ileus is adhesions resulting from previous surgeries, followed by tumors and hernias, 80% of cases originate in the small intestine. Paralytic ileus involves the cessation of intestinal motility without a physical obstruction, typically observed during the postoperative period or due to factors like electrolyte imbalances. Clinical symptoms include abdominal pain, cramping, bloating, and vomiting; emergency surgical intervention is vital, especially in cases where strangulation or necrosis is suspected. In the diagnostic process, physical examination is supplemented by direct abdominal radiography and computed tomography (CT), which is considered the gold standard. Although the treatment approach begins with conservative methods such as fluid-electrolyte support and decompression via nasogastric tubes, surgical intervention is inevitable for cases with complete obstruction or signs of ischemia. While pharmacological treatments can be utilized to restore intestinal motility postoperatively, undiagnosed cases must be rigorously evaluated for potential tumors.
