INTRODUCTION Wound related complications (WRC) are a significant source of morbidity in kidney transplant recipients, and may be mitigated by surgical approach. We hypothesize that the anterior rectus sheath approach (ARS) may decrease WRC and inpatient opiate use compared to the Gibson Approach (GA). METHODS This double-blinded randomized controlled trial allocated kidney transplant recipients aged 18 or older, exclusive of other procedures, 1:1 to ARS or GA at a single hospital. The ARS involves a muscle-splitting paramedian approach to the iliopsoas fossa, compared to the muscle-cutting GA. Patients and data analysts were blinded to randomization. RESULTS Seventy five patients were randomized to each group between August 27, 2019 and September 18, 2020 with a minimum 12 month follow-up. There was no difference in WRC between groups (p = .23). Nine (12%) and three patients (4%) experienced any WRC in the ARS and GA groups, respectively. Three and one Clavien IIIb complications occurred in the ARS and GA groups, respectively. In a multiple linear regression model, ARS was associated with decreased inpatient opioid use (β = -58, 95% CI: -105 to -12, p = .016). CONCLUSIONS The ARS did not provide a WRC benefit in kidney transplant recipients, but may be associated with decreased inpatient opioid use.
