Left retroperitoneal versus transperitoneal approach for abdominal aortic surgery - retrospective comparison of intraoperative and postoperative data.
BACKGROUND
The aim of our study was to evaluate the potential advantages of the left retroperitoneal (RP) approach for abdominal aortic surgery and compare the aortic exposure with the transperitoneal (TP) approach which is widely used.


METHODS
Total 55 consecutive patients who underwent elective aortic surgery between 1998 and 1999 were evaluated retrospectively. Thirty three patients underwent the RP exposure and 22 the TP approach in the treatment of abdominal aortic aneurysm or aortoiliac occlusive disease. Demographic data and premorbid status were not significantly different between these two groups. Fourteen intraoperative and postoperative parameters were monitored and statistically analyzed.


RESULTS
We found statistically significant differences in three of 14 intraoperative and postoperative parameters. Patients operated with the RP approach to the abdominal aorta were able to take clear fluids orally sooner. A statistically significant difference was also detected in the postoperative extubation time as RP patients were extubated almost one hour sooner than TP patients. Bowel function onset was statistically significantly faster return in the RP group. In the rest of recorded data there were no significant differences, however in all of follow-up parameters we found results in favour of RP group.


CONCLUSIONS
We conclude that the RP group of patients had statistically significant improvements three of 14 postoperative clinical parameters. (Tab. 3, Ref. 18.)
