Background: We reviewed the experimental surgery, related to bariatric surgery in laboratory animals, to consider new lines of research.
Methods: The literature on experimental surgery for morbid obesity since the mid-20th century was reviewed, focusing on existing techniques (malabsorptive, restrictive, mixed and experimental) and their associated metabolic component.
Results: In the field of laparoscopy, there is a clear tendency for large laboratory animals such as pigs to be used.
