title: Localization of the intestinal biopsy capsule in children by color-coded duplex sonography.
abstract: In 21 children from 3 months to 10 years and 5 months old, the position of the biopsy capsule before suction biopsy of the small intestine was examined by means of x-ray studies and both conventional and color-coded duplex sonography. In all cases, the biopsy capsule was correctly positioned under sonographic guidance. The sonographic finding was always confirmed by x-ray film and the histology of the tissue sample. The main obstacle for imaging the biopsy tube and capsule was intestinal gas due to crying and/or restlessness of infants under examination. However, it was always possible to define the position of the biopsy capsule sufficiently. These promising results allow us to recommend sonographic control of the intestinal tube before intestinal suction biopsy in infants and children. The advantages of this approach include lack of irradiation, which is especially important if the tube is an incorrect position after the first trial, bedside availability of sonographic equipment, lower risk of dislocation of the tube owing to shorter transport time, and continuous contact of medical staff with the infant.
