Aim. Mortality and morbidity of abdominal aortic aneurysm surgery have decreased significantly in time and transperitoneal approach (TPA) still preserves its popularity although retroperitoneal approach (RPA) is known to cause lower incidence and shortened duration of ileus, shorter intensive care unit (ICU) and hospital stay, earlier oral intake and less patient discomfort or pain.
Methods. One hundred and fifty patients that underwent abdominal aortic aneurysm repair at our Cardiovascular Surgery Center between January, 1990 and March, 2000 were reviewed and analyzed based on the elective/emergent nature of the surgery and the type of the incision as either TPA or RPA.
Results. Significantly shorter mechanical ventilation (15.2±3.8 vs 10.1±2.3 hours) and nasogastric decompression periods (40.6±10.7 vs 9.1±2.2 hours), less need for intravenous fluid supplementation and shorter ICU stay (29.5±14.8 vs 18.6±1.9 hours) were observed with the retroperitoneal approach (P<0.001). Need for allogeneic blood transfusion was, similar (1.3±1.4 vs0.9±0.4, P>0.05). Analysis of mortality and morbidity revealed bleeding as the major cause of mortality for ruptured aneurysm. A similar comparison between TPA and RPA groups, however, revealed no significant difference (P>0.05).
Conclusion. Retroperitoneal approach is a reliable technique causing less fluid-electrolyte imbalance with rapid restoration of gastrointestinal physiology. It causes less discomfort to patients with reduced need for analgesia. A shorter weaning period from mechanical ventilation is among the benefits for patients with co-morbid states.
