摘要:
目的探讨联合经会阴及经直肠腔内高频多普勒超声对肛周感染性病变的价值。 方法55例肛周感染性病变患者（包括49例肛周脓肿及6例肛瘘患者）先行经会阴超声检查，后联合经直肠腔内超声检查，使用高频彩色多普勒探头，观察病灶位置、毗邻结构关系及超声特征，并将超声检查结果与临床及手术结果对照。 结果经会阴超声确诊肛周脓肿48例，肛瘘4例，联合经直肠腔内超声后检查可多检出肛周脓肿4例，肛瘘2例，并可对各病灶进行准确定位、Parks分型，清晰显示病灶超声特征。 结论联合经会阴及经直肠腔内高频多普勒超声可清晰显示肛周感染性病变的解剖定位及周围毗邻结构，有效指导临床治疗。 Abstract:ObjectiveTo To evaluate the combination of transperineal with endoanal high-frequency doppler ultrasonography for detecting the lesions of perianal infection disease. MethodsFifty-five patients who suffered from perianal infection disease were enrolled in the study, of which includes 49 cases were perianal abscess and 6 cases, fistula-in-ano. The patients underwent transperineal ultrasound examinations with high frequency and doppler probe and, sequentially via endoanal ultrasound. The anatomic location, the adajacent soft-tissue and the ultrasound features of the lesions were evaluated. The efficiency of ultrasound was analyzed according to the operation and clinical diagnosis. ResultsForty-eight cases of perianal abscess and 4 cases of fistula-in-ano were detected via the transperineal ultrasonography. Combined the endoanal ultrasonography, additional 4 cases of perianal abscess and 2 cases of fistula-in-ano could be revealed clearly. The combined ultrasonography could show the anatomic locations, classification of Parks, and the relationship with the adjacent soft tissues, as well as its ultrasonography features. ConclusionCombination of transperineal with endoanal ultrasonography with high frequency and doppler technique could well document the perianal infection disease, providing clearly lesion anatomic location and its adjacent soft tissues relationship, which plays an vital role for the treatment of the disease. -
