Hidden Morbidity of Ventral Hernia Repair with Mesh: As Concerning as Common Bile Duct Injury?

Background Ventral hernia repair with mesh is increasingly common, but the incidence of long-term complications that necessitate mesh explantation is unknown. We aimed to determine the epidemiology of mesh explantation after ventral hernia repair and to compare this with common bile duct injury, a dreaded complication of laparoscopic cholecystectomy. Study Design We evaluated a retrospective cohort of patients undergoing ventral hernia repair by linking the all-payers State Inpatient Databases and State Ambulatory Surgery Databases for New York, California, and Florida. We followed patients longitudinally from 2005 to 2011 for the primary end point of mesh explantation, designated by concurrent procedure codes for ventral hernia repair and foreign body removal. We determined time to mesh explantation and calculated cumulative costs for surgical care, comparing these with historical data for common bile duct injury. Results During the study period, 619,751 patients underwent at least one ventral hernia repair (91% open, 9% laparoscopic). In a mean follow-up of 3 years, 438 patients (0.07%) had mesh removed at a median of 346 days after repair. Median cumulative cost for patients requiring mesh explantation was $21,889 vs $6,983 without (p Conclusions By this conservative estimate, complications of ventral hernia repair with implantable mesh are comparably as frequent as for common bile duct injury, but occur later in a patient's experience. Long-term follow-up is critically necessary to fully understand the ramifications of implanted devices.
