Summary

The retroperitoneal (RP) surgical approach for infrarenal aortic aneurysm (IAA) repair leads to fewer pulmonary complications, shorter hospital stays, and reduced costs compared to the transperitoneal (TP) method.

Area of Science:

  • Vascular Surgery
  • Surgical Outcomes Research
  • Health Economics

Background:

  • Infrarenal aortic aneurysm (IAA) repair is a common vascular surgery procedure.
  • The choice of surgical approach, transperitoneal (TP) versus retroperitoneal (RP), may influence patient outcomes and healthcare costs.

Purpose of the Study:

  • To compare the in-hospital morbidity and cost associated with transperitoneal (TP) versus retroperitoneal (RP) surgical approaches for elective infrarenal aortic aneurysm (IAA) repair.

Main Methods:

  • A comparative study of 96 patients undergoing elective IAA repair by two vascular surgeons.
  • Patients were divided into two groups: 50 with transperitoneal (TP) exposure and 46 with retroperitoneal (RP) exposure.
  • Key outcomes measured included hospital and ICU days, perioperative complications, and total hospital cost.

Main Results:

  • No significant differences in demographic features, aneurysm size, or operative blood loss between TP and RP groups.
  • Postoperative complication rates were similar, though a trend towards fewer pulmonary complications was observed in the RP group (p=0.11).
  • The RP approach was associated with significantly shorter ICU days (2 vs. 4, p=0.004) and hospital days (6 vs. 11, p=0.002), and significantly lower total hospital costs (mean difference $5,527, p=0.016).

Conclusions:

  • Retroperitoneal (RP) exposure for infrarenal aortic aneurysm (IAA) repair is associated with improved clinical outcomes and reduced healthcare costs compared to the transperitoneal (TP) approach.
  • RP exposure demonstrates potential benefits including decreased pulmonary complications and shorter hospitalizations.
  • RP exposure should serve as the benchmark for evaluating new techniques in IAA repair.
