Small Bowel Obstruction: Computed Tomography Features and Pitfalls

Strangulation Resulting from an Encasement of the Small Intestinal Loop by the Omentum without an Adhesive Band

“…Computed tomography (CT) has been shown to be useful in determining the site, level, and cause of obstructions. 3 In our case, CT findings showed extraluminal compression of a loop of the small bowel at two separate points suggesting an extraluminal band preoperatively. Identification of adhesion as a cause of SBO remains a diagnosis of exclusion that must be based on the finding of an abrupt change in bowel caliber without evidence of another cause of obstruction.…”

“…Bowel sounds were audible. The leukocyte count was 16,100/mm 3 , hemoglobin was 17.4g/dL, and platelet count was 420,000/mm 3 . A plain abdominal X-ray film showed several dilated small bowel loops with multiple air-fluid levels ( Fig.…”

Gastric bezoar with small bowel obstruction

“…This appearance is called 'small bowel feces-sign (6, 7). CT is acknowledged as the ideal methodology to determine the intestinal obstruction as it can demonstrate the reason and the level of obstruction (7,8).…”

Ileus: Radiological Approach in Daily Practice

“…Neoplasia: Primary neoplasia of the small bowel is rare (<2%) (6,7). Adenocarcinoma is observed more frequently.…”
