title: Mucosal biopsy.
abstract: Intestinal mucosal biopsy has become an invaluable tool for the evaluation of children with abdominal complaints. Multiple techniques and biopsy instruments have each been developed with advantages and limitations. Physicians caring for infants and children must be familiar with indications for tissue sampling, timing of the biopsies, and interpretations of biopsy specimens.
