摘　　要：目的:根据临床病理结果探讨低级别与高级别腹膜假性黏液瘤(Pseudomyxoma peritonei,PMP)的超声特点,以提高对该病的认识。方法:分析近20年于我院经穿刺活检证实为PMP的44例患者的超声声像图及超声报告,根据病理类型将其分为高级别PMP组(25例)和低级别PMP组(19例)。分别统计患者的腹膜厚度、腹膜回声、腹膜结构、腹膜结节、腹膜血流和腹水量、腹水回声以及"肝边缘扇形压迹"等超声征象,计量资料采用独立样本t检验,计数资料采用卡方检验,P<0.05为差异有统计学意义。结果:高级别PMP组与低级别PMP组患者年龄、腹膜厚度和腹水量间差异无统计学意义(t值分别为-1.05、1.54、0.26);PMP患者中腹膜结构呈虫蚀状改变及腹膜结节仅出现于高级别组,占16%;低级别PMP组与高级别PMP组腹膜回声、腹膜结构、腹水回声及"肝边缘扇形压迹"等超声征象间差异具有统计学意义。结论:低级别PMP较高级别PMP更易出现网状分布的无回声区、胶冻样腹水及"肝边缘扇形压迹",而高级别PMP中可见腹膜结节及较小的单发无回声区。Objective: To explore the ultrasonographic features of low-grade and high-grade pseudomyxoma peritonei according to the clinicopathological results, so as to improve the understanding of the disease. Methods: Forty-four patients with pseudomyxoma peritonei(PMP) confirmed by biopsy in our hospital in recent 20 years were analyzed. The thickness of peritonei, echo, structure, nodule, blood flow and ascites volume, ascites echo and “liver margin fan-shaped impression” were statistically analyzed. Independent samples t test was used for measurement data, chi square test was used for counting data,when P<0.05, the difference was considered statistically significant. Results: There was no significant difference in age, peritoneal thickness and ascites volume between high-grade PMP group and low-grade PMP group(t-value was-1.05, 1.54, 0.26 respectively). Peritoneal structure showed insect erosion in PMP patients and peritoneal nodules only appeared in high-grade group, accounting for 16% respectively;peritoneal echo, structure, ascites echo and “liver margin fan-shaped indentation” were detected in low-grade and high-grade PMP groups. And there were statistically significant differences in these signs. Conclusion: Low grade PMP are more likely to have reticular distribution of anechoic area, gelatinous ascites and fan-shaped indentation on the edge of organs. In high-grade PMP, there were peritoneal nodules and small single anechoic areas.
