摘要
目的探讨三维直肠腔内超声在定位肛周感染性疾病中内口、瘘管走形、脓腔位置、隐匿灶的价值。方法应用三维直肠腔内超声检查175例患者,其中肛瘘127例,肛周脓肿48例,根据其声像图特征进行内口定位、瘘管走行追踪及检测脓腔位置、隐匿灶。结果定位内口151例,准确率达86.3%(151/175);定位瘘管一条者90例,瘘管两条者37例;检测到55个脓肿病灶,其中皮下脓肿9例,黏膜下脓肿3例,黏膜皮下脓肿4例;低位肌间脓肿16例,高位肌间脓肿11例,坐骨直肠间隙脓肿3例,盆腔间隙脓肿2例。均经手术证实。结论应用三维直肠腔内超声检查肛周感染性疾病,能够准确定位内口、显示瘘管走行,有效检测脓腔位置及隐匿灶,能为临床治疗方法的选择提供必要的诊断依据。
Objective To evaluate the role of three-dimension transrectal ultrasonography in locating the internal opening,trend of fistulas,pus-filled cavity and occult focus in diagnosing perianal infections. Methods 127 cases of anal fistula and 48 cases of perianal abscess were examined by three-dimensional endoluminal ultrasonography. According to the characters of the sonogram and echogram,it located the internal opening,traced the trend of fistulas,and detected the pus-filled cavity＇s location and the occult focus. Results In 151 cases the internal opening was located with an accuracy rate of 86. 3% （ 151 /175） ; in 90 cases one fistula was located,and in 37 cases two fistulas were located. 55 cases of abscess were examined,including 9 cases of sub-cutaneous abscess,3 cases of sub-mucosal abscess,4 cases of mucosa subcutaneous abscess,16 cases of low intramuscular abscess,11 cases of high intramuscular abscess,3 cases of ischial rectal space abscess,and 2 cases of pelvic space abscess. All the above were confirmed by surgery. Conclusion Three-dimensional endoluminal ultrasonography in diagnosing perianal infections can accurately locate the internal opening,display the trend of fistulas,and effectually detect the pus-filled cavity＇s location and the occult focus. And it can provide essential diagnostic criteria for choosing the clinical therapy method.
