A new criterion to predict recurrence after laparoscopic ventral hernia repair: mesh/defect area ratio

Abstract

<b>Introduction:</b>Minimizing recurrence in hernia surgery is one of the major aims. Defining surgeon-dependent risk factors for recurrence is therefore of great importance in laparoscopic ventral hernia repair (LVHR). This study aims to analyze the predictive value of the mesh area/defect area ratio (M/D ratio) in terms of recurrence as a new criterion in LVHR.</br> </br> <b>Methods:</b> A total of 124 patients were enrolled in the study. Age, gender, hernia type, body mass index, defect size, size of the mesh, mesh overlapping, area of the defect, area of the mesh, M/D ratio, postoperative complications, follow-up time, recurrences and timing of recurrence were also recorded. The potential variables that may affect recurrence were examined by univariate and multivariate analysis.</br> </br> <b>Results:</b> There were 12 (9.7%) recurrences in our series. A statistically significant difference was found if either the mesh/defect ratio was ≤6 or >6 (p = 0.012). Multivariate analysis confirmed that M/D ratio was the only independent parameter for recurrence. </br></br><b>Conclusion:</b> Understanding M/D ratio concept and using it in surgical clinical practice may help reduce recurrence rates after LVHR.</br&gt.
