Abstract
Ventral hernia can be repaired through either an open or laparoscopic approach A major problem following hernia repair is recurrence and the technique used for hernia repair influences the rate of hernia recurrence Data from individual studies show that the area of mesh overlap used during hernia repair correlates with hernia recurrence but no metaanalyses have previously been published The aim of this review was to perform a metaanalysis to determine if the area of mesh overlap correlates with the rate of hernia recurrence after ventral and incisional hernia repairStudies from 1990 to 2013 that used a mesh in open or laparoscopic procedures and that reported both the area of mesh overlap beyond the fascial defect and the recurrence rate were assessed for inclusion in the final analysis A pooled estimation of combined overall risk was calculated according to a random effect modelA total of 95 articles with 111 study populations met all criteria and were included in the final analysis For open procedures results showed no correlation between the pooled estimation of risk for recurrence of ventral hernia and area of mesh overlap used for hernia repair 3 cm incidence rate 0065 3–5 cm incidence rate 0070 5 cm incidence rate 0060 In laparoscopic procedures the pooled estimation of risk for recurrence of hernia decreased with increasing area of mesh overlap 3 cm incidence rate 0086 3–5 cm incidence rate 0046 5 cm incidence rate 0014Editorial support was provided by Covidien Kamna Aggarwal PhD Patrice Becker Caroline Ritchie PhD and Ming Teng The literature search and data extraction was conducted by the Covidien Information Resource Center and statistical analyses were performed by Ming Teng
