abstract
PURPOSE: Synthetic mesh for herniorrhaphy has been placed under critical observation regarding the potential association of mesh placement and the subsequent development of autoimmune diseases. We sought to evaluate whether there is a link between synthetic polypropylene mesh repairs and the subsequent development of systemic/autoimmune disorders (SAID). STUDY DESIGN: Adult men undergoing hernia repair with mesh between January 2008 and December 2009 in New York State were identified using International Classification of Diseases, Ninth Revision, Modification procedure codes and Current Procedural Terminology Coding System, Fourth Edition codes. A control cohort of men undergoing colonoscopy was created with whom to compare outcomes. RESULTS: A total of 29,712 patients underwent hernia repair between January 2008 and December 2009. In the control cohort, 79,265 patients underwent colonoscopy. During the entire follow-up, 475 patients undergoing hernia repair and 1305 patients in the control cohort were diagnosed with autoimmune disease. When patients were matched based on demographics, comorbidities and procedure date, hernia repair was not associated with an increased risk of developing autoimmune disease over the entire follow-up time period. 1.6% of those in the hernia group vs. 1.7% of those in the colonoscopy group developed SAID [risk ratio (95% CI): hernia vs. colonoscopy 0.93(0.79-1.09)]. No association between mesh surgery and increased risks of SAID was found at any of the specified time points (6 months, 1 year, and 2-year follow-up). CONCLUSIONS: Mesh-based hernia repair was not associated with the development of autoimmune diseases compared to those undergoing routine screening colonoscopy.
