摘要
精索脂肪瘤是腹膜外脂肪经腹股沟内环突出形成的真性脂肪瘤。发生率一般在20％～30％。常由腹膜外脂肪从深环中脱出延续而造成，分叶状的后腹膜脂肪进入深环使其扩张，从而导致腹股沟疝与精索脂肪瘤的形成。BMI越高精索脂肪瘤越容易发生。同时也发现精索脂肪瘤在NyhusTypeⅡ及Ⅲb型的患者存在更高的发生率，说明了精索脂肪瘤的发生与疝的类型有关系，疝越大越容易发生。精索脂肪瘤的术前诊断不易，其临床表现与腹股沟疝及其相似。超声检查是一种安全而有效的方法，对诊断腹股沟疝和脂肪瘤的确诊率高达92％。只要腹膜外脂肪组织疝入腹股沟管，在手术中尽可能的将脂肪瘤切除，并按腹股沟疝行修复手术。
Cord lipoma is a ture lipoma,it is a protrusion of extraperitoneal fatty tissue through the internal inguinal ring. The incidence is between 20% to 30%. It is often caused by a protrusion of extraperitoneal fatty tissue through the internal inguinal ring, lobular retroperitoneal fat insinuates itself through the internal ring and over time dilates it. Patients with a higher BMI are more prone to having a cord lipoma. Incidence of lipoma associated with Type Ⅱ and Ⅲ hernias was higher,it is suggest that the incidence of lipoma associated with the type of hernias and patients with a larger hernias are more prone to having a cord lipoma. The cord lipoma is difficult to diagnosis before surgery, because it is similar to hernias in symptom. Ultrasound is safe and useful in finding hernias and cord lipoms, the overall accuracy is 92%. It is necessary to resect lipomas and repair as long as the extraperitoneal fatty tissue through into the inguinal canal.
