Inguinal hernia repair is a common surgical procedure, and the majority of operations worldwide are performed ad modum Lichtenstein (open tension-free mesh repair). Until now, no suitable surgical training model has been available for this procedure. We propose an experimental surgical training model for Lichtenstein's procedure on the male and female pig.
In the pig, an incision is made 1 cm cranially to the inguinal sulcus where a string of subcutaneous lymph nodes is located and extends toward the pubic tubercle. The spermatic cord is located in a narrow sulcus in the pig, thus complicating the procedure if operation should be done in the inguinal canal. The chain of lymph nodes resembles the human spermatic cord and can be used to perform Lichtenstein's hernia repair.
This experimental surgical model has been tested on two adult male pigs and three adult female pigs, and a total of 55 surgeons have been educated to perform Lichtenstein's hernia repair in these animals.
This new experimental surgical model for training Lichtenstein's hernia repair mimics the human inguinal anatomy enough to make it suitable as a training model. The operation facilitates the training in the positioning and fixation of the mesh and can be performed numerous times on the same pig. It is therefore a useful training method for inexperienced surgeons to obtain experience in aspects of the Lichtenstein procedure.
腹股沟疝修补术是一种常见的外科手术，全球大多数手术都是采用 ad modum Lichtenstein（开放式无张力网片修补术）进行的。到目前为止，还没有适合这种手术的培训模型。我们提出了一种用于男性和女性猪的 Lichtenstein 手术的实验性外科培训模型。
在猪身上，在腹股沟襞上方 1 厘米处做一个切口，这里有一串皮下淋巴结，并向耻骨结节延伸。在猪身上，精索位于一个狭窄的沟中，如果在腹股沟管中进行手术，这会使手术变得复杂。淋巴结链类似于人类的精索，可以用于进行 Lichtenstein 疝修补术。
这个实验性的外科模型已经在两只成年雄性猪和三只成年雌性猪身上进行了测试，共有 55 名外科医生在这些动物身上接受了 Lichtenstein 疝修补术的培训。
这个用于培训 Lichtenstein 疝修补术的新的实验性外科模型模拟了足够的人类腹股沟解剖结构，使其成为一种合适的培训模型。该操作有助于培训网片的定位和固定，并可在同一头猪上多次进行。因此，对于缺乏经验的外科医生来说，这是一种获得 Lichtenstein 手术经验的有用培训方法。
