A shorter skin incision technique for the repair of infrarenal abdominal aortic aneurysms.

Purpose: We evaluated the effectiveness of a shorter skin incision technique for the treatment of infrarenal abdominal aortic aneurysms (AAA). The aim of the present study was to evaluate whether or not the difference in the length of the skin incision contributed to an early recovery after the operation.

Methods: Between October 2001 and December 2004, we performed 105 elective repairs for AAA. The patients were divided into three groups according to the length of the skin incision as follows: group A, less than 15 cm, group B, from 15 cm to less than 20 cm, and group C, 20 cm or more.

Results: There was no significant difference in the intraoperative course among the three groups. The duration of paralytic ileus was shorter in group A than in group C (2.0 +/- 0.9 days versus 3.2 +/- 2.3 days; P = 0.0428). Although the periods before removal of nasogastric suction and before starting a solid diet were slightly shorter in group A than in groups B and C, there were no statistically significant differences.

Conclusion: We define minimally invasive vascular surgery as surgery performed with a small abdominal skin incision that does not expose the intestine to air while providing a good operative field that does not place any undue stress on the surgeon.
