Abstract

Objective: Our study aimed to investigate the imaging feature and the usefulness of computed tomography (CT) in diagnosing intestinal obstruction due to herniation. Materials and Methods: This retrospective study reviewed 19 patients (comprise 12  patients with internal herniation and 7 with external herniation). All patients underwent CT diagnosis and were surgically treated at Vietduc Hospital, Hanoi, Vietnam, from August 2018 to Jun 2020. Descriptive the imaging features of two types of bowel obstruction and then compare with operative descriptions. Results: Bowel obstruction due to external herniation were chiefly due to obturator hernia, which accounts for 50%. CT accurately diagnoses external hernia and predicts strangulation and intestinal ischemia in 100% of cases. Herniation due to mesenteric defect secondary after abdominal surgery accounts for 71.5% of internal hernias. CT imaging can precisely diagnose bowel obstruction complications and predicts strangulation and intestinal ischemia; the positive predictive value accounts for 95.9% and 100%, respectively. Conclusion: Computed tomography is the modality of choice in diagnosing herniated bowel obstruction, incredibly accurate in diagnosing obturator herniation and complications of bowel ischemia in the external hernia. CT can also assist in internal herniation cause diagnosis and predicting bowel ischemia.
