Abstract

Introduction
Pelvic organ prolapse (POP) affects half of middle-aged women. Quality of life (QOL) is reduced in a similar way to Parkinson disease. Functional reconstructive surgery allows an improvement in the QOL. The widespread diffusion of laparoscopic sacrocolpopexy (LS) in the management of female genital organ prolapse is hampered by its presumed length and technical difficulties. This surgery is a reference technique that requieres a surgical learning curve. During the learning curve, it is advisable practising with the ovine model (OM) as a previous step to performing the surgery in humans.
The aim of our study is to compare laparoscopic techniques and anatomy of pelvic structure between OM and human.
Design
OM and logistics were provided by Jesús Usón Minimally Invasive Surgery Centre. Experienced urologists and gynecologists were able to practise laparoscopic colposacropexy during a course offered by this centre. All findings were documented and recorded. Informed consent was obtained from all the patients involved.
Results
Although the sheep is a quadruped, its pelvis and vagina are similar in size to that of human. Differences regarding trocar placement, tissue laxity, peritoneum morfology and uterus conservation were described. Nevertheless, both surgeries are quite similar and overlap.
Further, OM it’s economically accessible and there are less ethical contraints than with non-human primates.
Conclusion
Animal model practising improves surgical management of this technique. OM is a valuable tool in the learning curve of LS.
