Meckel's diverticulum: possible detection by combining pentagastrin with histamine H2 receptor blocker.

Abstract

A Meckel's scan was performed on a 7-yr-old boy because of rectal bleeding. He was premedicated with pentagastrin (6 micrograms/kg subcutaneously) followed by 259 MBq (7 mCi) [99mTc]pertechnetate intravenously. The study was essentially negative. Because of persistent rectal bleeding and a strong clinical suspicion of a Meckel's, a repeat study was performed 6 wk later. He received pentagastrin as before, but this time was also given a histamine H2 receptor blocker (zantac). A Meckel's diverticulum was clearly evident.
