The rabbit model serves as a valuable operative experience and helps to establish new techniques for abdominal and thoracic endosurgery.

ABSTRACT

Minimally invasive surgery in infants requires great experience and highly specialised skills. However, in most paediatric surgical departments, the number of patients requiring such surgery is usually small and the personal experience of the surgeon limited. An experimental setting with small animals could improve these training conditions if it adequately simulates the underlying situation and conveys beneficial surgical experiences. The authors implemented an endosurgical training model with New Zealand white rabbits. The mean body weight was 3.3 (range 2.9-3.5) kg. The abdominal cavity had a volume of about 580 ml and the thoracic cavity a volume of about 250 ml, comparable with those of a newborn baby. Several relevant techniques were established (gastrostomy, colostomy, gut biopsies, lung biopsies, and anastomosis of the oesophagus). Overall, the rabbit model served to refine technical skills and operative experience. In paediatric surgical departments with a specific focus on endosurgery in the abdominal and thoracic cavities, this training model could help to introduce new techniques and add valuable educational strategies.
