Background: The purpose of this study was to determine whether a surgeon without special skills can perform minimal incision abdominal aortic aneurysm repair as safely and effectively as traditional retroperitoneal aneurysmectomy.
Methods: After informed consent, eligible patients were randomized into minilaparotomy and retroperitoneal groups. The minilaparotomy repair consisted of a short transabdominal midline incision, intraabdominal retraction of the bowel, control of back bleeding with balloon catheters, and hand-sewn anastomoses. The retroperitoneal approach was performed through a left vertical-lateral abdominal incision.
Results: Twenty-six patients were randomly treated by minilaparotomy approach (n = 14) or retroperitoneal approach (n = 12) from December, 1999, to May 2001. Parameters for speed of recovery were indistinguishable and of no clinical significance. In the long-term follow-up (mean period, 27 months), no patients in the minilaparatomy group complained of discomfort from the incision, whereas 4 patients in the retroperitoneal group complained of discomfort (P < 0.05).
Conclusions: Minilaparotomy approach can be performed safely and effectively without specialized skill. With regard to wound discomfort, the minilaparotomy technique is excellent. The minilaparotomy approach is therefore a useful alternative to traditional repair.
