Less invasive aortic surgery: the minilaparotomy technique

Area of Science:

• Vascular Surgery
• Minimally Invasive Surgical Techniques

Background:

• Abdominal aortic aneurysms (AAA) and aortoiliac occlusive disease (AIOD) are significant vascular conditions.
• Traditional open surgical repair involves extensive incisions and bowel retraction.

Purpose of the Study:

• To evaluate a less invasive minilaparotomy technique for infrarenal aortic exposure.
• To assess the impact of this technique on AAA and AIOD treatment outcomes.

Main Methods:

• Prospective study of 40 patients undergoing minilaparotomy aortic exposure (<10 cm incision).
• Comparison with a contemporary group of AAA patients treated with open midline incision.
• Techniques included intra-abdominal bowel retraction and hand-sewn anastomoses.

Main Results:

• No significant differences in operating room time, intraoperative, perioperative morbidity, or mortality between groups.
• Minilaparotomy group showed significantly shorter intensive care unit stays (1.0 vs 1.8 days).
• Minilaparotomy resulted in faster return to diet (3 vs 4.7 days) and shorter overall hospital stay (4.9 vs 7.3 days).

Conclusions:

• Minilaparotomy exposure is a safe and effective method for infrarenal AAA and AIOD.
• This technique achieves comparable quality outcomes to open surgery.
• Benefits include reduced postoperative ileus, shorter hospital stays, and decreased resource utilization.
