Norwegians Study comparison of Laparoscopic vs. Open Aortobifemoral Bypass Surgery

Norwegian researchers conducted a randomized study to run a cost comparison analysis of laparoscopic versus open aortobifemoral bypass surgery. 


Laparoscopic aortobifemoral bypass (LABFB) surgery has become an established treatment procedure for aortoiliac occlusive disease (AIOI), Trans-Atlantic-Inter-Society Consensus II (TASC II), type D lesions. However, studies with an economic evaluation of this procedure are sparse. The main purpose of this Norwegian-backed study was to compare the costs of LABFB and open aortobifemoral bypass (OABFB) surgery as reported in Dovepress.

Patients and Methods

This Norwegian-backed study is a substudy of a larger randomized controlled prospective multicenter trial, Norwegian Laparoscopic Aortic Surgery Trial (NLAST). Perioperative data was collected on 70 patients undergoing surgery for AIOD, TASC type D lesions. 34 patients were randomized to LABFB and 36 patients to OABFB. Treatment costs, reports Dovepress, were calculated for the two operative treatments until 30 postoperative days. In addition to fixed and variable costs, direct and indirect costs were included.


The mean total cost of the LABFG was 19,798 Euros and for OABFB 34,016 Euros until postoperative days. Laparoscopic procedure was 14,218 Euros less costly than the open procedure. The main factor leading to less cost of LABFB was shorter length of hospital stay (mean 5.3 days, 95% CI 4.1-6.5) as compared to OABFB (mean 10.1 days, 95% CI 7.5-12.6). Ten patients, three in the LABFB and seven in the OABFB group, had complications that resulted in reoperations within the 30 postoperative delays. The mean cost of treatment for the complicated patients was 49,349 Euros and 82,985 Euros, respectively, for LABFB and OABFB.


The Norwegian researchers concluded that laparoscopic aortobifemoral bypass procedure costs less than open aortobifemoral bypass for the treatment of advanced aortoiliac occlusive disease.
