超声在腹膜假黏液瘤诊断及临床分级中的应用价值

目的 研究腹膜假黏液瘤的声像图特征,分析超声检查在腹膜假黏液瘤诊断及评估临床分级的应用价值.方法 术前对50例患者进行超声检查,记录临床特点、声像图特征、剖宫产术中表现及病理结果,对比术中表现分析腹膜假黏液瘤的声像图特征,并分析不同级别腹膜假黏液瘤的声像图差异.结果 在超声检查中,48例患者发现腹腔积液,仅2例患者未发现明显腹腔积液.43例发现肝脾周围压迹, 33例发现腹盆腔不均质包块,34例发现明显网膜增厚,形成网膜饼,2例发现腹腔淋巴结肿大.肝脾周围压迹及腹盆腔包块在不同级别腹膜假黏液瘤差异具有统计学意义(P<0.05),而腹腔积液特点、网膜饼及淋巴结肿大差异无统计学意义(P>0.05).结论 术前超声检查在腹膜假黏液瘤的诊断具有一定的临床应用价值.不同级别腹膜假黏液瘤声像图特征有重叠,但有些表现可以帮助鉴别诊断.

Value of Sonography in the Diagnosis and Pathologic Staging of Pseudomyxoma Peritonei before Surgery.

Objective To analyze the sonographic features of pseudomyxoma peritonei and the value of sonography to diagnose this diease and assess the pathologic grades of this disease before the surgery. Methods Fifty patients with Pseudomyxoma Peritonei underwent sonographic examinations before surgery. The clinical factures, sonographic characteristics, representations in the surgery and pathologic grades were recorded. Then we compared sonographic characteristics with representations in the surgery and analysed the differences between different pathological level of Pseudomyxoma Peritonei. Results Ascites was found in 48 cases, only 2 cases were not. The liver and spleen pressure trace was found in 43 cases, block mass in the abdominal or pelvic cavity was found in 33 cases, obvious "retinal cake" was found in 34 cases, abdominal lymph node enlargement was found in 2 cases. The liver or spleen pressure trace and the abdominal or pelvic mass revealed statistically significant differences between different level of pseudomyxoma peritonei, but ascites, retinal cake and lymph node enlargement had no statistical difference. Conclusion Preoperative sonographic examinations have some clinical application value in the diagnosis of pseudomyxoma peritonei. Ultrasonographic features in different level of pseudomyxoma peritonei are overlap, but certain may help us to make some differential diagnosis.
