Laparoscopic surgery has revolutionized surgical technique by creating less post operative pain, quicker recovery time, and less invasive procedures. Due to equipment limitations and lack of training availability, these surgical techniques have rarely been performed in rodents, the most widely used animals in biomedical research. Instead, larger animals have been utilized for biomedical studies, training, and instrument development for laparoscopy. The constant use of larger species in research is problematic due to cost, public concern, and laws and regulations. Advances in the development of transgenic rodents and the improvement of laparoscopic technologies better suited for smaller animal makes rodent laparoscopic surgery an attractive option. Many basic research studies in fields such as reproduction, physiology, pharmacology, oncology, and toxicology rely on repetitive biopsies of abdominal organs, all of which can be performed laparoscopically. Utilization of laparoscopic surgery in rodents promotes both animal welfare and scientific progress through reduction, refinement, and the replacement of larger species.
