Platelet-rich plasma PRP vs. absorbable mesh as cruroplasty reinforcement: a study on an animal model.

Background: Reinforcement of posterior cruroplasty has been proposed to minimize the failure of hiatal hernia repair (HHR). The applications of autologous platelet-rich plasma (PRP) and absorbable mesh are barely reported in this area.

Aims: To analyze local macroscopic and microscopic changes induced by mesh vs.
