Objective To analyze the findings and diagnostic value of multi-slice spiral CT in obturator hernia with intestinal obstruction. Methods 15 cases of patients with obturator hernia and intestinal obstruction surgically and pathologically confirmed in our hospital from January 2012 to June 2015 were taken as the research objects. The imaging findings of preoperative multi-slice spiral CT (MSCT) were retrospectively analyzed. Results Preoperative MSCT examination showed small intestine obstruction, which manifested as expansion and pneumatosis of small intestine, 3cm or longer in diameter; Obstruction regions showed a typical beak sign, nodular hernia sac neck in obturator canal region, incarceration of hernial sac between external obturator muscle and pectineus; There were 8 cases of small intestinal ischemia and necrosis, showing samll intestinal wall thickening and edema on CT, fuzzy mesenteric fat clearance, with a small amount of ascites. There were 4 cases of perforation, showing visible small amount of free gas in the abdominal cavity. Conclusion The MSCT characteristics of obturator hernia with intestinal obstruction are typical. Its beak like and other direct signs can obviously omprove the preoperative diagnostic accuracy of the disease and provide important imaging evidence for the operation.
