Popis: BACKGROUND: Mesh infection (CMI) after ventral hernia repair (VHR) is uncommon, with an incidence of 1-7%. The aim of this observational retrospective study was (1) to analyse the incidence and aetiologies of late CMI (one or more years after prosthetic repair) in a series of VHR patients, (2) to identify pre-operative and perioperative variables related to late CMI and (3) to consider possible prevention measures to reduce its occurrence. MATERIALS AND METHODS: A multivariate analysis of a prospective database of patients with a diagnosis of CMI who underwent open VHR between January 2014 and December 2023 at a tertiary centre was conducted. Institutional review board approval was obtained. Two groups of patients were compared: patients with onset of CMI less than one year after VHR (early CMI [ECMI] group) and patients with onset of CMI (sinus or suspected infection) one or more years after VHR (late CMI [LCMI] group). RESULTS: At a median of 31.6 months (range: 19-55 months) of post-operative followup, 108 cases of CMI were reported, of which 64 cases were clinically diagnosed within one year of VHR (ECMI group) and 44 cases after one year (LCMI group). The most frequent clinical presentation of CMI was post-operative chronic sinus (94%) and mesh extrusion through the wound (6%). In multivariate analysis, pre-operative predictors associated with LCMI were BMI > 30 (p < 0.001; OR 1.980, p=0.002) and steroid or immunosuppressive drug use (p < 0.001; OR 1.06, p=0.004). Previous hernia repair using PTFE mesh was also a predictor of LCMI (p < 0.002; OR 2.11, p=0.000). Various factors, such as smoking, diabetes, previous hernia repair, presence of a stoma, operative time, concomitant enterotomy or post-operative SSI, were not significant indicators of LCMI. CONCLUSIONS: CMI is one of the most prevalent and challenging complications of VHR. Obesity (BMI > 30) and immunosuppression, as well as the use of ePTFE mesh in the previous hernia repair, are predictors of LCMI after VHR; studies of these factors may reduce and prevent the occurrence of LCMI.
