To assess the value of abdominal ultrasonography in the diagnosis of acute appendicitis and the influence of gender, physical constitution, experience of the radiologist and the time evolution of the disease on the results of diagnostic indices.
We prospectively evaluated 156 patients with clinical diagnosis of acute appendicitis who underwent laparoscopic appendectomy and abdominal ultrasonography, together with pathology of the excised appendices. Patients were allocated in relation to BMI in both groups (below or above 25 kg/m²) and radiologists, in three groups according to their professional experience (less than five years, between five and 10 years and more than 10 years). The survey also assessed the influence of gender and time of disease progression using the median of 36 hours.
The sensitivity and specificity of abdominal ultrasonography for diagnosing appendicitis were 64.9 and 72% respectively. Gender, body mass index, length of experience of the radiologists in the three groups and time of onset of symptoms showed no significant differences in the establishment of sonographic diagnosis of acute appendicitis.
The abdominal ultrasonography showed low sensitivity and specificity and little contribution to the diagnosis of acute appendicitis. Gender, physical constitution, the experience of the radiologist and time of onset of symptoms did not affect the outcome of the sonography.
评估腹部超声检查在急性阑尾炎诊断中的价值，以及性别、体质、放射科医生经验和疾病时间演变对诊断指标结果的影响。
我们前瞻性地评估了156例临床诊断为急性阑尾炎的患者，这些患者接受了腹腔镜阑尾切除术、腹部超声检查以及切除阑尾的病理检查。根据体重指数（BMI）将患者分为两组（低于或高于25kg/m²），并根据放射科医生的专业经验将其分为三组（少于5年、5至10年和超过10年）。该研究还使用36小时的中位数评估了性别和疾病进展时间的影响。
腹部超声检查诊断阑尾炎的敏感性和特异性分别为64.9%和72%。在三组中，性别、体重指数、放射科医生的经验时长以及症状出现时间在急性阑尾炎超声诊断的确立上均无显著差异。
腹部超声检查显示出较低的敏感性和特异性，对急性阑尾炎的诊断贡献不大。性别、体质、放射科医生的经验和症状出现时间均未影响超声检查结果。
