摘要
目的观察对比腹股沟斜疝与非疝患者不同状态下的腹内压力(IAP)及其变化,为探寻腹股沟斜疝的病因提供线索。方法对2006年11月至2007年3月间收治的19例腹股沟斜疝及20例非疝疾病患者,采用膀胱测压法测定 IAP;分别测量斜疝组和非疝组患者的平卧静息时、平卧做腹部加压(Valsava 动作)时、直立时、直立做加压时的 IAP,并分别进行组间比较;并对两组患者的平卧与直立静息 IAP 差、平卧加压前后 IAP 差、直立加压前后 IAP 差及平卧与直立腹部加压时 IAP 差进行比较。结果静息状态下两组患者无论平卧还是直立时 IAP 差异均无统计学意义(P>0.05);腹部加压动作后,平卧位两组患者腹内压力也无明显差异(P>0.05),而直立位腹部加压动作时斜疝组腹内压力较对照组显著增高(P<0.01);两组患者平卧时做加压动作、平卧与直立静息状态下的 IAP差异无统计学意义(P>0.05)。但在直立位做加压动作或做加压动作时直立较平卧位的 IAP 差,斜疝组与非疝组相比差异有统计学意义(P<0.05)。结论斜疝的形成与直立、增加腹内压力的因素及解剖改变相关;斜疝患者的 IAP 可因腹腔或腹壁的改变较正常人更易升高。
Objective To investigate intra-abdominal pressure （IAP） and its changes in patients with indirect inguinal hernia and non-hernia diseases. Methods Supine IAP （ SIAP）, supine Valsava IAP （SVIAP） ,orthostatic IAP（OIAP） and orthostatic Valsava IAP（OVIAP） were measured by intra-vesicle pressure measurement in 19 indirect inguinal hernia patients and 20 non-hernia patients, respectively. The differences of IAP between orthostatic and supine position in quiescent condition （OSIAPD） ,before and after taking Valsava maneuver in supine position （SVIAPD） or in orthostatic position （ OVIAPD）, orthostatic and supine position when taking Valsava maneuver （OSVIAPD） were compared between the two groups. Results There was no significant differences in SIAP, OIAP, SVIAP, OSIAPD, SVIAPD between the two groups （P 〉0. 05）. While patients with indirect inguinal hernia had higher OVIAP （P 〈 0. 05 ）. Significant differences in OVIAPD and OSVIAPD was found between the two groups （P 〈0. 05 ）. Conclusions The etiology of indirect inguinal hernia were related to orthostatic position, increasing IAP and changes of anatomic structures. The IAP is prone to elevated in patients with indirect inguinal hernia.
