探讨超声在诊断腹膜继发性肿瘤疾病中的临床应用价值

Investigation of clinical application value of ultrasound in peritoneal secondary tumor

目的探讨超声在诊断腹膜继发性肿瘤疾病中的临床应用价值。方法 12例腹膜继发性肿瘤疾病患者,总结腹膜继发性肿瘤疾病超声图像的特点,并复习相关文献。结果腹膜假性黏液瘤患者超声表现为腹腔内可见黏液腹腔积液,深度11.3～12.2 cm,肠管受压,腹膜增厚,厚度3.0～3.5 cm,积液内呈蜂窝状改变,可见多个网状、光带状分隔,并可见成堆分布的点状高回声随体位改变而缓慢移动。卵巢癌、胃癌、肝癌和结肠癌腹膜转移患者的超声表现为：腹腔内可见大量腹水,腹水深度7.1～12.0 cm,于腹水中可见大网膜僵硬、明显增厚,厚度3.6～6.7 cm,呈＂网膜饼＂状,并于盆腔及腹腔内可见卵巢、胃、肝、结肠的原发肿瘤病灶。结论超声技术可以清晰的显示腹膜继发性肿瘤疾病的特征性声像图特点,具有方便捷、快捷、准确性较高的优点,有益于临床诊断该类疾病。

Objective To investigate clinical application value of ultrasound in peritoneal secondary tumor. Methods There were 12 patients with peritoneal secondary tumor, and their characteristics of ultrasound images for peritoneal secondary tumor were summarized, along with related literature. Results Ultrasound manifestations in peritoneal pseudomyxoma patients included visible seroperitoneum in abdominal cavity with depth of 11.3～12.2 cm, compressed intestinal canal, thickened peritoneum with thickness of 3.0～3.5 cm, alveolate changes in effusion, multiple reticular and light strip separation, and piles of moved punctiform high level echo in different positions. Ultrasound manifestations in ovarian cancer, stomach cancer, liver cancer, and colon cancer peritoneal metastasis included massive ascites in abdominal cavity with depth of 7.1～12.0 cm, stiffed and thickened omentum majus in ascites with thickness of 3.6～6.7 cm, appearance of ＂omentrm cake＂, primary tumor lesions of ovary, stomach, liver, colon in pelvic cavity and abdominal cavity. Conclusion Imaging characteristics of peritoneal secondary tumor can be clearly shown by ultrasound, which contains advantages of convenience, fast speed, and high accuracy. This method is beneficial for clinical diagnosis of this disease.
