jejunal biopsy

jejunal biopsy
removal of a piece of the lining (mucosa) of the upper small intestine. This can be done by a surgical operation but is usually performed by a gastroduodenoscope or a special metal capsule, swallowed by the patient. When the capsule is in the jejunum a small knife within it is triggered by suction on an attached tube, cutting off a small piece of mucosa. The specimen may be examined microscopically to assist in the diagnosis of coeliac disease, Whipple's disease, or intestinal infections, or its enzyme content may be measured chemically to detect, for example, lactase deficiency.
