*Purpose: To investigate recurrence and surgical site infection (SSI) rates and risk factors after incisional hernia (IH) repair following abdominal transplantation.
*Methods: A retrospective review of patients who underwent IH repair following abdominal transplantation at our institution was performed. Primary outcomes were IH recurrence and SSI as defined per the CDC.
*Results: There were 78 patients who underwent IH repair and there were 110 IH surgeries. Baseline patient and surgical characteristics are shown in Tables 1 and 2. There were no significant differences between age, BMI and comorbidities between recurrence and non-recurrence groups. Recurrence rate was 35% (n=24) and SSI rate was 15% (n=12) (Table 3). Multiple hernia repair was the only factor strongly associated with recurrence (p<0.05) (Table 4). None of the analyzed factors had an association with SSI.
*Conclusions: In this study, multiple IH repair is the only factor strongly associated with IH recurrence after abdominal organ transplantation. Once an IH recurred, it was with near certainty that another IH repair would fail again. Therefore, choosing personalized approaches is the most critical component in IH repair in transplant patients. Randomized studies with a larger cohort are necessary to improve the findings of this study.
