Bowel Obstruction

Abstract

Small bowel obstruction and large bowel obstruction account for approximately 20% of cases of acute abdominal surgical conditions. The role of the radiologist is to answer several key questions: Is obstruction present? What is the level of the obstruction? What is the cause of the obstruction? What is the severity of the obstruction? Is the obstruction simple or closed loop? Is strangulation, ischemia, or perforation present? In this presentation, the radiologic approach to and imaging findings of patients with known or suspected bowel obstruction are presented.

Clinical study of acute intestinal obstruction in tertiary care centre

“…6,7 Causes of bowel obstruction include adhesions, hernias, volvulus, endometriosis, inflammatory bowel disease, appendicitis, tumors, diverticulitis, ischemic bowel, tuberculosis, and intussusception. 1,2 Small bowel obstructions are most often due to adhesions and hernias while large bowel obstructions are most often due to tumors and volvulus.…”

“…Ultrasound or MRI may help in the diagnosis of children or pregnant women. 1 The condition may be treated conservatively or with surgery. 2 In small bowel obstruction about 25% require surgery.…”

“…5 Complications may include sepsis, bowel ischemia, and bowel perforation. 1 The prognosis for non-ischemic cases of small bowel obstruction is good with mortality rates of 3-5%, while prognosis for small bowel obstruction with ischemia is with mortality rates as high as 30%.…”

Evaluation of acute intestinal obstruction cases due to gastrointestinal bezoars: 5-year-experience

“…Akut bağırsak tıkanıklığı hayatı tehdit eden bir durumdur ve genellikle acil cerrahi girişim gerektirir 15,16 . İntestinal ve kolonik obstrüksiyonlar, acil cerrahi girişim gerektiren akut karın vakalarının yaklaşık %20'sini oluşturmaktadırlar 16 .…”

“…As causas mais comuns são diversos fatores extrínsecos, como aderências hérnias, carcinomatose, volvo e endometriose, ou por fatores intrínsecos, como tumores, estenoses, intussuscepção, doenças inflamatórias, entre outros [4].…”
