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. Cross-sectional imaging (MRI, CT and US) techniques, gained large application in gastrointestinal radiology in the emergency department; they are indicated as first line techniques in the diagnosis, staging and follow-up. Hernial orifices can be congenital, including both normal foramina or recesses and unusual apertures resulting from anomalies of peritoneal attachment and internal rotation, or acquired if caused by inflammation, trauma and previous surgery, like gastric by-pass for bariatric treatment and liver transplantation. Due to the growing popularity of these surgical procedures, the overall incidence of internal hernias has been recently increasing. Materials and methods: A cross sectional observational study in the department of Radiodiagnosis at Tertiary care Teaching Hospital over a period of 1 year. Ethical permission was taken from the Institutional committee. Informed consent was taken from all the patients included in the study. Twelve patients with small intestinal obstruction were selected. Patients willing to participate in the study Both males and females Patient age between 30 to 60 years Patients presenting with small intestinal obstruction and internal hernias on CT scan History of post-surgery. Result: Among the 90 cases, 50% were reported as Paraduodenal hernias, 11.1% as Pericecal hernia, and 8.9% as hernia through foramen of Winslow. On CT scan abdomen, the Paraduodenal hernias were seen as encapsulated cluster of dilated bowel loops with a saclike appearance. Conclusion: The clinical diagnosis of an internal hernia being most often unknown, cross-sectional imaging methods with multiplanar reformatting, particularly computed tomography, are essential in the management of this pathology.
