The filling and evacuation of Zenker's diverticula were scintigraphically examined before and after operation to quantify their functional relevance. These results were correlated with the symptoms of the patients and the findings of the barium swallow x-ray examination using cineradiography.
Sequential and static esophageal scintigraphies were performed in 17 patients with Zenker's diverticulum before and after laser surgical diverticulotomy. We used a gamma camera system in 45 degrees LAO-position after application of 15 ml of tea which was marked with 99mTc-DTPA. Filling and evacuation of the diverticulum were expressed in proportion to the administered activity. Relative volumes of the diverticula were obtained from cineradiography by using the height of the neighbouring cervical vertebra, and the clinical symptoms were divided into 4 groups.
Zenker's diverticula could be verified visually and quantitatively by scintigraphy. The precise temporal course of the reduction of activity in the diverticulum was exactly determined. The scintigraphic retentions correlated with the x-ray volumes with a coefficient ranging from 0.55 to 0.85. Clinical symptoms also were not very closely related to scintigraphic and x-ray findings, respectively.
The esophageal scintigraphy allows quantification of the filling and evacuation of Zenker's diverticula, thus it is suitable for objectivization of the functional relevance of the diverticula. That's why the esophageal scintigraphy should be taken to the diagnosis of diverticula in addition to the clinic and the x-ray examinations. The method is especially useful to evaluate the results after diverticulotomy.
对Zenker憩室手术前后进行闪烁扫描检查，以量化其功能相关性。将这些结果与患者症状及使用电影放射摄影术的吞钡X线检查结果相关联。
对17例Zenker憩室患者在激光手术憩室切开术前和术后进行连续和静态食管闪烁扫描。在给予15 ml标记有99mTc-DTPA的茶水后，采用γ相机系统在左前斜45度位置进行检查。憩室的充盈和排空以给药活性的比例表示。通过使用相邻颈椎的高度从电影放射摄影术中获得憩室的相对体积，并将临床症状分为4组。
通过闪烁扫描可以直观且定量地验证Zenker憩室。准确确定了憩室内活性降低的精确时间进程。闪烁扫描滞留与X线体积相关，系数范围为0.55至0.85。临床症状分别与闪烁扫描和X线检查结果也并非密切相关。
食管闪烁扫描可对Zenker憩室的充盈和排空进行量化，因此适用于使憩室功能相关性客观化。这就是为什么除了临床和X线检查外，食管闪烁扫描应纳入憩室的诊断。该方法对于评估憩室切开术后的结果特别有用。
