Total laparoscopic bypass is safe and effective for aortoiliac occlusive disease.

Abstract

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. A monocentric retrospective study was conducted between October 2002 and October 2011; we performed 173 total laparoscopic aortic surgeries to treat AIOD. 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. 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.
