To evaluate the appropriate use of the pararectal retroperitoneal approach (RPA) in abdominal aortic aneurysm (AAA) repair, we retrospectively compared the RPA with the transperitoneal approach (TPA). Fifty-four patients in whom the RPA was used and 92 who had the TPA were included in the study. The mean operating time was 286 minutes with the RPA and 252 minutes with the TPA. Intraoperative blood transfusions were necessary in 9.3% of patients who had the RPA and 16.2% who had the TPA. As assessed by computerized tomographic scanning, the mean size of the postoperative retroperitoneal hematoma was 440 mL in the RPA group and 180 mL in the TPA group. Ileus resolved a mean of 3 days postoperatively in the RPA group and 5 days postoperatively in the TPA group. The mean length of postoperative hospitalization was 21 days in the RPA group and 23 days in the TPA group. Prolonged postoperative ileus occurred in no patients in the RPA group and in three patients in the TPA group. None of the differences in outcomes between the groups were significant. Our findings indicate that, in carefully selected patients, the pararectal RPA is suitable for AAA repair.
