  1. 腹外疝Ventral Hernia 病因 1、腹壁强度减弱 2、腹内压力过高 疝的组成 1、疝门 Hernia Ring 2、疝囊 Hernia Sac 3、疝内容物

  2. 4、疝被盖 类型 1、易复性疝 2、难复性疝 3、滑动性疝 (Reducible) (Irreducible) (Sliding Hernia) 4、嵌顿性疝 5、绞窄性疝 (Incarcerated) (Strangulated )

  3. 疝嵌顿或绞窄的三大主要症状： 1、疝块突然疝出肿大 2、疝块坚实、变硬、压痛 3、机械性肠梗阻症状

  4. 腹股沟疝 局部解剖

  5. Nyhus Classification of Groin Hernia • Type I: Indirect inguinal hernia—internal inguinal ring normal (e.g., pediatric hernia) • Type II: Indirect inguinal hernia—internal inguinal ring dilated but posterior inguinal wall intact; inferior deep epigastric vessels not displacedType III: Posterior wall defect • A. Direct inguinal hernia • B. Indirect inguinal hernia—internal inguinal ring dilated, medially encroaching on or destroying the transversalis fascia of Hesselbach’s triangle (e.g., massive scrotal, sliding, or pantaloon hernia) • C. Femoral hernia • Type IV: Recurrent herniaA. Direct • B. Indirect • C. Femoral • D. Combined

  6. 腹股沟斜疝 发病机理

  7. 临床表现 腹股沟区肿块、自行回复 肿块形状、膨胀性冲击感、指尖冲击感、 压迫内环试验、透光试验
