| 目的 观察腹膜假黏液瘤(PMP)的超声特征并与病理分型进行对照分析,探讨术前超声诊断PMP的价值。 方法 收集PMP患者的临床资料,根据病理学特征分腹膜弥漫性黏液腺瘤病(DPAM)、腹膜黏液腺癌病(PMCA)及交界性病变(PMCA-I/D)3型,分析不同病理分型的超声特征。 结果 经病理证实为PMP且有术前超声资料的患者49例,DPAM 14例、PMCA-I/D 17例、PMCA 18例。超声检查显示92.86%(13/14)DPAM、88.24%(15/17)PMCA-I/D和83.33%(15/18)PMCA存在腹腔积液。64.29%(9/14)DPAM、29.41%(5/17)PMCA-I/D和55.56%(10/18)PMCA的肝脏表面及35.71%(5/14)DPAM、11.76%(2/17)PMCA-I/D和27.78%(5/18)PMCA的脾脏表面有黏液结节产生的压迹。PMCA更倾向于伴有肝脏黏液结节浸润(P=0.045)。64.29%(9/14)DPAM、70.59%(12/17)PMCA-I/D和83.33%(15/18)PMCA伴腹膜种植结节。PMCA者更倾向于伴有网膜饼(P=0.018)。 结论 PMP的超声表现有一定特异性。虽然不同病理类型的患者均可出现内脏表面压迹和腹膜种植,但肝脏浸润和网膜饼更常见于PMCA。 |

| Objective To analyze the ultrasonic features of pseudomyxoma peritonei (PMP) and the ability of preoperative ultrasound to assess the pathological grades. Methods Clinical data of PMP patients were recorded. According to pathological features, patients were divided into disseminated peritoneal adeomucinosis (DPAM), peritoneal mucinous carcinomatosis (PMCA) and carcinomatosis with intermediate or discordant features (PMCA-I/D). The ultrasonic characteristics of PMP with different pathological classification were analyzed. Results Forty-nine patients of PMP who underwent preoperative ultrasonic examination were included. Fourteen patients were classified as DPAM, 17 as PMCA-I/D and 18 as PMCA. Ultrasound showed ascites in 92.86% (13/14), 88.24% (15/17) and 83.33% (15/18) cases of DPAM, PMCA-I/D and PMCA, respectively. Extrinsic compression and scalloping of the liver was found in 64.29% (9/14), 29.41% (5/17) and 55.56% (10/18) cases of DPAM, PMCA-I/D and PMCA, while scalloping of the spleen margin was detected in 35.71% (5/14), 11.76% (2/17) and 27.78% (5/18) cases, respectively. Liver implant nodules were more frequent in PMCA than in other types of PMP (P=0.045). Peritoneal implants were obvious in PMCA than DPAM and PMCA-I/D (83.33% vs 64.29% , 70.59% ), whereas omental cakes were more obvious in PMCA (P=0.018). Conclusion Ultrasonic findings are specific in PMP. Though scalloping of visceral and peritoneal implant nodules might appear in different pathological grades, liver implants nodules and omental cakes were more obvious in PMCA than in other types of PMP. |
