在食管细胞学检查中,有部分中、晚期食管癌由于病变部位狭窄,食管细胞采集器不能通过,而造成假阴性,影响了阳性率的提高。我室对在放射治疗前拉网检查的患者,如网囊未能通过狭窄区,采取快速充气摩擦法收集癌细胞。对33例患者中8例网囊未能通过狭窄区者,采用该法全部获得阳性结果。 In esophageal cytology, some esophageal cancers in the middle and advanced stages of the esophageal cell harvester cannot pass due to narrowing of the lesions, resulting in false negatives, which affects the improvement of the positive rate. In our department, patients who have been checked before radiotherapy, such as the sac failed to pass through the constricted area, were taken to collect cancer cells by rapid inflation. Eighteen of the 33 patients failed to pass through the stenosis area in 8 cases, and all positive results were obtained using this method.
