title: Peroral small-bowel biopsies in infants and children using a directable biopsy instrument.
abstract: Fifty children, ages 1 month to 12 years, underwent peroral jejunal biopsy with a four-way directional suction biopsy instrument (Medi-Tech). Mucosal specimens were obtained in 88% of attempted biopsies in an average time of 4 min. Fluoroscopy time was minimal, and there were no complications.
