Purpose:To evaluate the usefulness of CT for the diagnosis of the cause and localization of small bowel obstruction.
Materials and Methods: Out of a group of children who underwent a CT examination for a suspected small bowel obstruction, 19 patients with confirmed underlying disorders were identified and included in the study. Neonates and patients with duodenal obstruction were excluded from the study. The CT findings were analyzed for the location of obstruction site, abnormalities of the mesentery and mesenteric vessels, bowel wall thickening, closed loop obstruction, and strangulation. The obstruction site was divided into five parts. The preoperative CT diagnosis was compared with the final diagnosis.
Results: Causes of small bowel obstruction were intussusception (n = 6), appendiceal perforation (n = 4), transmesenteric internal hernia (n = 2), postoperative bands (n = 1), idiopathic multiple bands (n = 1), a foreign body (n = 1), a small bowel adenocarcinoma (n = 1), Meckel’s diverticulitis (n = 1), tuberculous peritonitis (n= 1) and Salmonella enteritis with bowel perforation (n = 1). The CT findings showed mesenteric vascular prominence (n = 13), omental or mesenteric infiltration (n = 10), localized bowel wall thickening (n = 7), closed loops obstruction (n = 3) and strangulation (n = 1). The obstruction site was identified in all cases. The causes of obstruction could be diagnosed preoperatively in 14 cases, but a preoperative diagnosis was difficult in 5 cases.
Conclusion: The causes of small bowel obstruction in children are variable, and CT is useful for evaluating the cause and localization of small bowel obstruction.
