目的：评价腹膜细胞刷刷检在良、恶性腹水鉴别诊断中的应用价值。方法：用自制腹膜细胞刷对２８例有中等量以上恶性腹水患者作腹膜刷检，并与腹水常规脱落细胞学检查、腹膜活检等方法进行比较。结果：腹水常规脱落细胞学检查肿瘤细胞的阳性率为４２．９％，腹膜病理活检４６．４％，腹膜刷检８２．１％；腹膜活检后腹水脱落细胞学检查肿瘤细胞的阳性率为６４．３％，腹膜刷检后８５．７％；腹膜活检和腹膜刷检同时进行后腹水脱落细胞学检查肿瘤细胞的阳性率增加至９６．４％。结论：腹膜刷检可提高良、恶性腹水的诊断正确率，是一种操作方便、安全有效的检查手段，值得进一步推广
Objective: To evaluate the value of peritoneal brush examination in the differential diagnosis of benign and malignant ascites. Methods: Peritoneal brushing was performed on 28 patients with moderate or severe malignant ascites using homemade peritoneal brush, and compared with routine cytology and peritoneal biopsy of ascites. Results: Ascites routine cytology of exfoliated cytology positive rate of tumor cells was 42.9%, peritoneal biopsy 46.4%, peritoneal brushing 82.1%; peritoneal biopsy cytology after the positive rate of 64 .3%, 85.7% after peritoneal brushing test; peritoneal biopsy and peritoneal brushing at the same time ascitic fluid cytology examination of the positive rate of tumor cells increased to 96.4%. Conclusion: Peritoneal brushing can improve the diagnostic accuracy of benign and malignant ascites, which is a convenient, safe and effective means of examination and is worth further promotion
