BACKGROUND/PURPOSE: History taking and physical examination alone no longer meet the surgeon's need in the diagnosis of inguinal hernia. Ultrasonography (US) provides a good and safe diagnostic tool for inguinal hernias in boys.
METHODS
From 1995 to 1997, 244 boys with inguinal hernias (41 bilateral and 203 unilateral), received preoperative US on both groins to confirm the diagnosis. Those with positive US findings, such as viscera or fluid in inguinal canal or widening of the internal inguinal ring, underwent surgery.
RESULTS
The accuracy of diagnosis with US and clinical assessment were 97.9% and 84%, respectively. More than 95% of widening of internal inguinal rings (>4 mm) proved to be hernias. There were two direct inguinal hernias and two femoral hernias, which were misdiagnosed by clinical examination, but proved to be diagnosed correctly by US.
CONCLUSIONS
US serves as a noninvasive and highly accurate diagnostic tool for inguinal hernias in boys. Using 4 mm as the upper limit of the normal diameter of the internal inguinal ring, an occult inguinal hernia can be easily detected before surgery.
背景/目的：仅靠病史采集和体格检查已无法满足外科医生对腹股沟疝的诊断需求。超声检查（US）为男孩腹股沟疝提供了一种良好且安全的诊断工具。
方法
1995年至1997年，244例患有腹股沟疝的男孩（41例双侧，203例单侧）在术前接受了双侧腹股沟区的超声检查以确诊。超声检查结果呈阳性者，如腹股沟管内有脏器或液体或腹股沟内环增宽，则接受手术治疗。
结果
超声检查和临床评估的诊断准确率分别为97.9%和84%。超过95%的腹股沟内环增宽（>4毫米）被证实为疝。有2例直疝和2例股疝，临床检查误诊，但超声检查确诊。
结论
超声是男孩腹股沟疝的一种无创且高度准确的诊断工具。以4毫米作为腹股沟内环正常直径的上限，术前可轻松检测出隐匿性腹股沟疝。
