Retroprosthetic seroma after laparoscopic ventral hernia repair: incidence, risk factors and clinical significance

Background The seroma generated between the abdominal viscera and the prosthesis (retroprosthetic seroma), after laparoscopic ventral hernia repair (LVHR) with the implant of an intraperitoneal mesh is an unknown entity with few references in the literature. Our objective is to analyze its incidence, clinical repercussions and course of retroprosthetic seroma during the first 3 months post-operation and the factors related to its appearance, such as the relationship to preprosthetic seroma, the size of the prosthesis and the patient BMI.
