[Double contrast small bowel examination--a methodologic comparison using transnasal and peroral probes].
A new flexible probe to be introduced through the nose was used for the intubation of the jejunum for double-contrast small bowel enema. The new probe has a diameter of only 2.8 mm and was better tolerated than the normally applied Camus probe. Nevertheless, the failure rate (intubation of jejunum not successful) with the new probe as compared to the Camus probe was higher (17% versus 1%). We, therefore, conclude that the new probe should mainly be used by experienced examiners.
