The aim of this study was to compare the clinical outcomes and hospital costs associated with two different meshes in robotic transabdominal preperitoneal inguinal hernia repair (IHR). Patients who underwent IHR were assigned to either the polyester self-gripping (PSG) or the polypropylene (PP) group depending on the mesh used. A propensity score matching analysis was performed to obtain balanced populations. Postoperative variables included complications such as surgical site events and recurrences. Hospital costs included all possible expenses generated by the surgery during the hospitalization period. From a database of IHR performed between February 2012 and July 2022, 131 PSG patients were matched to 131 PP repairs. Median operative time was shorter in the PSG group [55 (40-78) vs. 80 (60-116) minutes, p鈥�<鈥�0.001]. No intraoperative complications were recorded. Patients who received the PSG mesh experience reduced immediate postoperative pain compared to the PP group. Average follow-up time was 35.2聽months in the PSG group vs. 12.5聽months in the PP group (p鈥�<鈥�0.001). Median Comprehensive Complication Index was comparable in both groups (p鈥�=鈥�0.489), with no surgical site infections logged. No cases of chronic pain were noted. Only two recurrences were recorded in the cohort, both of them in the PSG repairs. Hospital costs were USD $232 higher in the PP group but did not statistically differ (p鈥�=鈥�0.523). There were no differences between the polyester self-gripping and the polypropylene mesh in terms of postoperative complications, clinical outcomes and hospital costs. Surgeons may opt for either meshes depending on their preferences and familiarity with each of the products.
