BACKGROUND
Free intraperitoneal fluid can be an important sign in an abdominal inflammatory process or abdominal trauma. It is often present in children with abdominal pain, but it is a nonspecific finding. A minimal amount of free intraperitoneal fluid is considered normal.
OBJECTIVE
The purpose of this study was to evaluate the incidence, location and volume of free fluid in the abdomen and pelvis in a population of asymptomatic children.
MATERIALS AND METHODS
In this prospective study, we performed clinically indicated abdominal and pelvic sonography, using high-resolution transducers, in 200 asymptomatic children: 104 (52%) girls, 96 (48%) boys; ages 6 days-15 years (mean 3 years 8 months). US studies were performed and prospectively evaluated by two experienced pediatric radiologists. Patients with any condition that could result in the accumulation of free intraperitoneal fluid as well as postpubertal girls were excluded from the study.
RESULTS
Free intraperitoneal fluid was seen in 12 children (6%), only in the pelvis. Fluid volume never exceeded 1 ml.
CONCLUSION
Our study suggests that 1 ml or less of free intraperitoneal fluid detected in the pelvis is probably insignificant.
背景
游离腹腔积液在腹部炎症或腹部创伤中是一个重要的征象。游离腹腔积液常存在于腹痛的儿童中，但这是非特异性发现。极少量的游离腹腔积液被认为是正常的。
目的
本研究旨在评估无症状儿童人群中腹腔和盆腔游离液的发生率、部位和量。
材料和方法
在这项前瞻性研究中，我们对 200 例无症状儿童进行了临床指征的腹部和盆腔超声检查，使用了高分辨率探头：104 例（52%）女孩，96 例（48%）男孩；年龄 6 天至 15 岁（平均 3 岁 8 个月）。US 研究由两名有经验的儿科放射科医生进行并前瞻性评估。有任何可能导致游离腹腔积液积聚的情况以及青春期后的女孩均被排除在研究之外。
结果
12 例（6%）儿童仅在盆腔中可见游离腹腔积液，液体量从未超过 1 毫升。
结论
我们的研究表明，在盆腔中检测到 1 毫升或更少的游离腹腔积液可能是无意义的。
