Abstract: Objective To evaluate the value of multislice spiral CT (MSCT) in diagnosing rare small-bowel obstruction (SBO). Materials and Methods The MSCT imaging features of 18 patients with rare cause of SBOs were reviewed retrospectively. Results The presence of SBOs could be diagnosed in all patients on MSCT. The underlying etiology of SBOs were diagnosed correctly in 77.22% of patients. Among the 18 patients, congenital intestinal atresia were found 1 case, foreign body in 3 cases, bezoar in 2 cases, abdominal cocoons in 1 cases, internal abdominal hernia in 2 cases, obturator hernia in 4 cases, small intestinal volvulus in 5 cases. Associated complications were arised in 5 patients with ischemia in 2 patients and perforations in 3 patients. Conclusion MSCT are not only useful for diagnosis and evaluation the severity of rare SBOs, but also useful for identifing the cause and associated complications of rare SBOs.
