下腹正中小切口兔输精管结扎术

Vasectomy Via a Small Ventral Midline Incision in Rabbits

目的探讨下腹正中切口兔输精管结扎术可否减少术后早期并发症。方法正常雄性日本大耳白兔14只(约4月龄),7只(随机选择)经阴囊切口暴露睾丸和输精管后靠近附睾尾进行输精管结扎,另7只从耻骨联合上方的腹正中线上作一小切口,暴露腹股沟管内的输精管后进行输精管结扎。术后10天进行局部解剖,观察手术局部的变化。结果与经阴囊切口相比,经腹正中切口的兔输精管结扎术可明显减轻阴囊水肿以及睾丸、附睾与周围组织的粘连。结论远离阴囊和附睾的经下腹正中切口的兔输精管结扎术,可减轻手术创伤,减少术后早期并发症。

Objective To determine whether vasectomy, in rabbits, via a ventral midline incision could reduce early post-operational complications. Methods Of 14 normal male Japanese white rabbits （ aged approximately 4 months） , 7 （randomly chosen） were subjected to vasal ligation near the cauda epididymidis after exposure of the testis and vas deferens via a scrotal incision, and the other 7 subjected to vasectomy after exposure of the vas in the inguinal canal through a small ventral midline incision. Anatomical dissection was performed to observe the local changes at 10 days after operation. Resttlts The vasectomy via the ventral midline incision, compared to that via the serotal incision, considerably reduced scrotal edema and adhesion of the testis and epididymis with the surrounding tissue. Conclusion Rabbits vasal ligation that is distant from the scrotum and epididymis via a ventral midline incision could lessen surgical trauma and reduce early post-operational complications.
