Summary
Total laparoscopic repair of abdominal aortic aneurysms (AAA) shows comparable short-term outcomes to open surgery. While technically demanding, laparoscopy does not negatively impact the postoperative recovery for AAA patients.
Area of Science:
- Vascular Surgery
- Minimally Invasive Surgery
- Surgical Outcomes
Background:
- Abdominal aortic aneurysm (AAA) repair is a major surgical procedure.
- Minimally invasive techniques are increasingly explored to improve patient outcomes.
- Comparing laparoscopic and open AAA repair is crucial for surgical decision-making.
Purpose of the Study:
- To compare perioperative and postoperative outcomes between total laparoscopic AAA repair and open AAA repair.
- To evaluate the feasibility and safety of laparoscopic AAA repair.
- To identify potential advantages of laparoscopic AAA repair over conventional open surgery.
Main Methods:
- A case-control study matched 30 patients undergoing total laparoscopic AAA repair (group I) with 30 patients undergoing open AAA repair (group II).
- Patients were matched based on AAA morphology and American Society of Anesthesiologists class.
- Statistical analysis included chi-squared tests for categoric data and Mann-Whitney tests for continuous data.
Main Results:
- Laparoscopic AAA repair involved longer operative times (255 vs 200 minutes) and aortic clamping times (80 vs 50 minutes) compared to open repair (P < .001 and P < .0001, respectively).
- Total blood loss was significantly higher in the laparoscopic group (1600 mL vs 1000 mL, P < .01).
- Postoperative outcomes showed significantly shorter duration of ileus (2 vs 3 days), earlier return to diet (4 vs 8 days), earlier ambulation (3 vs 4 days), and lower narcotic requirements (P < .05) in the laparoscopic group.
Conclusions:
- Total laparoscopic AAA repair demonstrates comparable short-term outcomes to open surgical repair.
- Laparoscopic AAA repair is technically more demanding peroperatively but does not adversely affect the postoperative course.
- These preliminary findings suggest laparoscopy is a viable alternative for AAA repair with potential benefits in early recovery.
