Purpose: Retroprosthetic seroma (RS) is defined as a fluid collection located between the abdominal viscera and the intraperitoneal mesh implanted during surgery. Aim of this study is to report the incidence and clinical impact of RS based on the type of mesh implanted during laparoscopic ventral hernia repair (LVHR). Materials and Methods: Patients who underwent LVHR were allocated in group A if expanded polytetrafluoroethylene (ePTFE) mesh was used during surgery and in group B if other types of mesh were used. Patients were evaluated on postoperative day (POD) 1 and 7 with physical examination and 1 month after surgery by physical examination and with an abdominal computed tomography scan, respectively. Results: Sixty patients were included. Of these 41 patients (68.3%) were included in group A and 19 patients (31.7%) in group B. Signs of RS were not observed in any patient on POD 7. One month after surgery, RS was observed in 13 patients (21.6%). One patient (7.7%) with RS experienced great discomfort and mesh detachment, and underwent a second surgical treatment. All RSs were observed in group A, and the difference with group B was statistically significant (P = .005). Conclusions: The use of ePTFE mesh is related to the development of RS. The treatment of choice without clinical symptoms should be conservative. Randomized control trial and prospective studies with a larger sample size and control group are required to confirm these data, although this study shows a high evidence of the relation of RS and the type of mesh.

Abstract

Purpose: Retroprosthetic seroma (RS) is defined as a fluid collection located between the abdominal viscera and the intraperitoneal mesh implanted during surgery. Aim of this study is to report the incidence and clinical impact of RS based on the type of mesh implanted during laparoscopic ventral hernia repair (LVHR). Materials and Methods: Patients who underwent LVHR were allocated in group A if expanded polytetrafluoroethylene (ePTFE) mesh was used during surgery and in group B if other types of mesh were used. Patients were evaluated on postoperative day (POD) 1 and 7 with physical examination and 1 month after surgery by physical examination and with an abdominal computed tomography scan, respectively. Results: Sixty patients were included. Of these 41 patients (68.3%) were included in group A and 19 patients (31.7%) in group B. Signs of RS were not observed in any patient on POD 7. One month after surgery, RS was observed in 13 patients (21.6%). One patient (7.7%) with RS experienced great discomfort and mesh detachment, and underwent a second surgical treatment. All RSs were observed in group A, and the difference with group B was statistically significant (P = .005). Conclusions: The use of ePTFE mesh is related to the development of RS. The treatment of choice without clinical symptoms should be conservative. Randomized control trial and prospective studies with a larger sample size and control group are required to confirm these data, although this study shows a high evidence of the relation of RS and the type of mesh.
