超声对大网膜良恶性病变的诊断价值

Clinical value of ultrasonography in the differentia diagnosis of benign and malignant lesions in greater omentum

目的探讨超声对大网膜良恶性病变的诊断价值。方法观察62例大网膜增厚患者的超声表现,与超声引导下穿刺活检结果进行对比分析。结果 62例患者中,结核性腹膜炎36例,腹膜假性黏液瘤5例,转移性腺癌18例,恶性间皮瘤2例,非霍奇金淋巴瘤1例。增厚大网膜良性病变表现以高回声、块状增厚及0级血流为主,恶性病变以低回声、结节状及Ⅲ级血流为主,二者比较差异均有统计学意义(P﹤0.05)。结论大网膜良恶性病变声像图特点存在明显差异,超声检查有助于二者的鉴别诊断,具有重要临床价值。

Objective To evaluate the clinical value of uhrasonography in the differentia diagnosis of benign and malignant lesions in greater omentum.Methods The uhrasonography features of thickened omentum in 62 patients with abdominal distention and ascites of unknown origin were retrospectively analyzed and their pathology results by ultrasound-guided biopsy were contrasted.Results Among 62 patients with thickened omentum, there were 36 cases of tuberculous peritonitis, 5 cases of pseudomyxoma peritonei, 18 cases of metastatic adenocarcinoma, 2 cases of malignant mesothelioma and 1 case of non- Hodgkin＇s lymphoma.Benign lesions mainly appeared as hyperechogenicity, massive thickening and grade 0 of blood flow, while malignant lesions were shown as hypoechogenicity, nodules and grade III of blood flow.The differences were statistically significant （P 〈 0.05 ）.Conclusion Uhrasonographie features of benign and malignant lesions in greater omentum are significantly different. Uhrasonography is beneficial to differential them and has significant clinical value.
