超声对原发性肠脂垂炎的检查价值

目的 探索超声对原发性肠脂垂炎的检查价值.方法 回顾性分析37例经随访证实的原发性肠脂垂炎的超声表现,观察病变部位、内部回声、大小、边界及血流分布.结果 37例原发性肠脂垂炎均发生于结肠侧旁,其中位于盲肠周围3例,升结肠周围4例,降结肠周围4例,乙状结肠周围26例.超声声像图特征表现为偏高回声包块,呈倒三角形或椭圆型,边界欠清,平均长径(3.9±0.9) cm,平均厚度(2.3±0.8) cm,彩色多普勒包块内未发现明显的血流信号,部分病例周边可见少量血流信号.结论 原发性肠脂垂炎超声表现有其特征性,结合临床表现容易作出提示诊断.

Clinical Value of Ultrasonography in the Diagnosis of Primary Epiploic Appendagitis

Objective The purpose of this study was to explore the diagnostic value of sonography in the primary epiploic appendagitis(PEA).Methods A retrospective analysis of thirty-seven patients with PEA proved by successive follow-up was performed and the ultrasonic manifestations of PEA including location,echogenicity,size,margin and vascularity were observed.Results All of these thirty-seven cases with PEA occurred around the colons.Among these cases,three were found around cecum,four around ascending colon,four around the descending colon and twenty-six around sigmoid respectively.Sonographic imaging of PEA exhibited inverted triangle or oval-shaped alternations with slight hyper-echogenicity and less clear border.The average length and thickness of the lesion were(3.9±0.9) cm and(2.3±0.8 ) cm respectively.No obvious blood flow signal was detected in the mass by color Doppler flow imaging,but in some cases a small amount of blood flow signals around the mass was noticed.Conclusions PEA shows characteristic sonographic appearances,therefore,sonography is of great value in the diagnosis of PEA.
