A biopsy (tissue sample) is used to diagnose or monitor certain gastrointestinal problems. Common gastrointestinal biopsies are:
Percutaneous Liver Biopsy
A liver biopsy will allow the physician to examine a small piece of liver tissue for injury or damage to the organ. A few days before the procedure, the patient will need to have blood tests. The test is done under anesthesia using a thin biopsy needle. The child is observed for several hours or overnight after the procedure.
Rectal Suction Biopsy
This procedure can be done in clinic and does not require sedation. A small instrument inserted into the rectum takes a small painless biopsy (tissue sample).
Rectal Punch Biopsy
This procedure is done under anesthesia and obtains a larger rectal biopsy (tissue sample).
Diseases or Conditions
The following diseases or conditions may require one or more forms of biopsy.
