Small bowel length measured by radiography.

The jejunoileal length was measured on double-contrast small bowel enema radiographs, obtained from 10 patients who had been investigated for abdominal pain. Previous endoscopic and radiologic examinations had excluded lesions of the upper and lower GI tract. The length of the small bowel ranged from 230 to 370 cm, with an average length of 280 cm.
