99mTc-pertechnetate scanning is now recognized as a useful means of detecting Meckel's diverticula. When these contain gastric mucosa and present with ulceration and bleeding, the ectopic gastric mucosa can be identified by its secretion of 99mTc-pertechnetate. However, the secretions of normal gastric and salivary glands can pool in the gut and simulate a Meckel's diverticulum. We believe the diagnostic procedure of choice to include both continuous nasogastric suction and continuous sequential gamma camera images. To support this view, we present cases illustrating 1) that 99mTc-pertechnetate can appear in the bowel within the first few minutes of administering 99mTc-pertechnetate, even in the absence of a Meckel's diverticulum; 2) that rapid sequential camera views are helpful but not definitive in distinguishing such bowel activity from a Meckel's diverticulum; and 3) that continuous nasogastric suction most successfully eliminates this interference.
99m锝高锝酸盐扫描现已被公认为检测梅克尔憩室的一种有用方法。当这些憩室含有胃黏膜并出现溃疡和出血时，异位胃黏膜可通过其分泌99m锝高锝酸盐而被识别。然而，正常胃和唾液腺的分泌物可在肠道内积聚并模拟梅克尔憩室。我们认为，首选的诊断程序应包括持续鼻胃吸引和连续的序贯γ相机图像。为支持这一观点，我们展示了一些病例，说明：1）即使没有梅克尔憩室，99m锝高锝酸盐也可在注射后几分钟内出现在肠道内；2）快速序贯相机视图有助于但不能明确区分这种肠道活动与梅克尔憩室；3）持续鼻胃吸引最成功地消除了这种干扰。
