成人腹股沟区面积及患者基本特征与腹股沟疝发病的相关研究

目的 了解成人腹股沟区面积与患者基本特征（性别、年龄、身高、体质量、BMI指数）以及腹股沟疝发病的关系，寻找预防腹股沟疝发生的方法。方法 分析2013年1～2月，川北医学院附属医院在彩色超声引导下测量238例腹股沟疝和非疝患者腹股沟区的三条边长，用海伦公式计算腹股沟区的面积，分析其与患者基本特征和腹股沟疝发病的关系。结果 全部患者患侧腹股沟区面积大于健侧（t=2．30，P=0．02）。腹股沟疝患者腹股沟区面积大于正常对照患者（t=2．63，P=0．009）。男性疝患者腹股沟区面积大于正常对照男性患者（t=5．58，P=0．000）。女性疝患者腹股沟区面积大于女性对照患者，但差异无统计学意义（t=1．30，P：0．20）。女性腹股沟区面积显著大于男性（t=7．20，P=0．000）。全部患者腹股沟区面积与年龄呈正相关（r：0．237，P=0．000）。男性患者腹股沟区面积与身高无相关性（r=-0．04，P=0．50），与体质量（r=-0．15，P=0．015）和BMI呈负相关（r=-0．16，P=0．009）。结论 成人腹股沟区面积与性别、年龄相关。男性腹股沟区面积与体质量和BMI显著呈负相关，腹股沟区面积越大，发生腹股沟疝的危险性越高，适当健体增肥可能有助于预防腹股沟疝。

Measurement of inguinal area for its relationship with patient characteristics and inguinal hernia morbility in adult patients

Objective To explore the relationship between inguinal area of adult patients, patient characteristics gender,age,height,weight,body mass index （BMI）] and inguinal hernia morbility, and to seek for the methods of inguinal hernia prediction and prevention. Methods The length of three sides of inguinal regions of 238 adult patients, including 65 inguinal hernia patients and 173 patients without inguinal hernia, were measured by color doppler uhrasonography, and then the inguinal areas were calculated according to Heron~ formula. The relationships between inguinal area of adult patients,patient characteristics and inguinal hernia morbility were analyzed. Results The inguinal area of the sides with hernia was significantly larger than the normal sides （ t = 2. 30, P = 0.02 ）. The inguinal areas of inguinal hernia patients and male inguinal hernia patients were respectively larger than the patients without hernia and male patients without hernia （t =2. 63,P =0. 009） ; （t =5.58,P =0. 000） ]. But the inguinal area of female inguinal hernia patients was not remarkably larger than female patients without hernia （ t = 1.30, P = 0.20 ）. The inguinal area of female patents was notably larger than males （ t = 7.20, P = 0.000）. The inguinal area of all patients had significantly positive correlation with age （ r = 0. 237, P = 0. 000 ）. For male patients, inguinal area had no correlation with height （ r = - 0. 04, P = 0.50 ）, but had significantly negative correlation with weight （r= -0. 15,P=0.015） and BMI （r= -0. 16,P=0.009）. Conclusions The inguinal area of adult patients has correlation with age and gender. In adult males, inguinal area is negatively correlated with weight and BMI. Larger inguinal area has a higher risk of inguinal hernia. Appropriate exercise and proper weight gain may help to reduce the morbility of inguinal hernia.
