Total laparoscopic juxtarenal abdominal aortic aneurysm repair

OBJECTIVES: This study describes our experience of total laparoscopic juxtarenal abdominal aortic aneurysm (JAAA) repair. METHODS: Between February 2002 and October 2007, we performed 148 total laparoscopic AAA repairs, including a subset of 13 patients who underwent a laparoscopic JAAA repair. Median age was 70 years (range, 50-81years). Median aneurysm size was 55 mm (range, 50-80 mm). Eight patients were in American Society of Anesthesiologist class II, and five were in class III. We used laparoscopic transperitoneal left retrorenal approaches and suprarenal clamping in all patients. RESULTS: We implanted tube grafts in nine patients and bifurcated grafts in four. No conversions to open repair were required. Median operative time was 260 minutes (range, 180-355 minutes). Total median aortic clamping time was 77 minutes (range, 36-105 minutes). Median suprarenal clamping time was 24 minutes (range, 9-37 minutes). Median blood loss was 855 mL (range, 215-2100 mL). No patients died. One patient had a postoperative coagulopathy with hemorrhagic syndrome. Five patients had moderate systemic complications, including four renal insufficiencies without dialysis and one grade I ischemic colitis. Liquid diet was reintroduced after 1 day (range, 1-7 days). Most patients were ambulatory by day 3 (range, 2-17 days). Median lengths of stay were 48 hours (range, 12-336 hours) in the intensive care unit and 10 days (range, 4-30 days) in the hospital. With a median follow-up of 19 months (range, 1-36 months), patients had complete recovery without graft anomalies. CONCLUSION: Total laparoscopic JAAA repair is feasible and worthwhile for patients. Prior experience in laparoscopic aortic surgery is essential to perform these challenging procedures. Despite these encouraging results, a greater experience is required to ensure the benefit of this technique compared with open repair.
