title: Patterns of intestinal activity with Meckel's scintigraphy.
abstract: Three patterns of intestinal activity were noted in a review of 64 patients studied with Tc-99m sodium pertechnetate for suspected Meckel's diverticulum: no bowel activity seen (37.5%), bowel activity visualized after stomach activity (39.1%), and diffuse bowel activity seen simultaneously with stomach activity (23.4%). The latter pattern, which is relatively common, could mask a true Meckel's diverticulum and lead to either a false-negative or indeterminate diagnosis. A series of 10 dogs was also studied to evaluate the effects of fasting and feeding on the intestinal pattern. No definite relationship was observed.
