Study on role of computed tomography in internal hernias

Abstract

Introduction: An internal hernia (IH) is defined as the protrusion of abdominal viscera, most commonly small bowel loops, through a peritoneal or mesenteric aperture into a compartment in the abdominal and pelvic cavity. Usually these patients present with acute abdomen and CT scan becomes the first modality of diagnosis. Aim of the study: To study of role of Computerized Tomography in internal hernias. Materials and Methods: Twelve patients who presented with acute abdomen and having internal hernias on CT scan were studied for the patient demographics, for the type and location of hernia on CT scan.Results: A total of twelve patients were studied. There was slight male predominance and the male to female ratio was 2:1. Majority of patients were among 51-60 years ie, 58.3% followed by 41 to 50 years which had 25% patients. The paraduodenal hernias were most common, accounting for 50% of the cases followed by pericecal hernias that were 16.6% cases. In the present study, twelve cases of internal hernias were diagnosed on CT scan and all correlated well with the intraoperative diagnosis.Conclusion: Clinical diagnosis of internal hernias is often difficult and complicated internal hernias often present as acute intestinal obstruction where urgent diagnosis becomes extremely important. Imaging studies play an important role in the early diagnosis for internal hernias. It is important for the radiologist to recognize these entities so that prompt diagnosis and early intervention can be instituted.
