RESUMEN
OBJECTIVE: We reviewed our experience of total laparoscopic aortic bypass surgery performed for aortoiliac occlusive disease (AIOD), focusing on early 30-day mortality and morbidity and short-term and midterm outcomes. METHODS: A monocentric retrospective study was conducted between October 2002 and October 2011; we performed 173 total laparoscopic aortic surgeries to treat AIOD. RESULTS: Patients included 135 men and 38 women. The mean age was 57.2 years (range, 34-77 years). The median operative time was 205 minutes (range, 120-420 minutes), the median aortic clamping time was 50 minutes (range, 20-120 minutes), and the mean blood loss was 263 mL (range, 0-3200 mL). Conversion to open surgery was necessary in 12.1% of patients. The 30-day postoperative mortality rate was 2.3% (four of 173 patients). Major morbidity occurred in 6.9% of patients. Wound complications occurred in 8%. Four patients had a groin infection (2.3%), treated by surgical trimming in three patients and replacement of the prosthesis by venous bypass in one patient. Early graft thrombosis (within 30 days) occurred in one patient (0.6%), requiring reintervention. With a mean follow-up of 42 months (standard deviation, 37 months), 96% of bypasses were patent. Patency rates at 3 and 5 years were 97% and 85% respectively. CONCLUSIONS: In selected patients, laparoscopic aortic bypass surgery for AIOD is a safe procedure with an acceptable morbidity rate, short intensive care unit and hospital stay, fast recovery, and early return to general diet. It is a good indication after failure of endovascular surgery.
