Purpose: This systematic review aims to evaluate the published literature regarding totally laparoscopic aortobifemoral bypass (LABF) surgery in the treatment of aortoiliac occlusive disease (AIOD) or abdominal aortic aneurysms (AAA), compared with open aortobifemoral bypass surgery.
Materials and methods: A systematic review of the medical literature between 1990 and 2016 was performed, searching the medical databases Cochrane Library, OVID Medline, Embase and PubMed. Studies concerning totally LABF with or without control group and containing more than 10 patients were included in the analysis. Operative and aortic cross-clamping times, blood loss, rate of conversion to open surgery, mortality and morbidity within the first 30 postoperative days, hospital stay and primary and secondary patency of the graft were extracted and compared with open surgery when possible.
Results: Sixty-six studies were deemed eligible for inclusion in this review, 16 of them matched the inclusion criteria for quantitative synthesis. The patient material consisted of 588 patients undergoing totally LABF, 22 due to AAA, and the remaining 566 for AIOD. Five comparative studies regarding AIOD compared 211 totally LABF procedures with 246 open procedures. Only one study concerning AAA was eligible for inclusion, and this study did not provide a comparison against an open group. The operating and aortic cross-clamping times were shorter in the open group. Conversion rates ranged from 0% to 27%. There was no statistically significant difference in mortality between the two groups (p=0.64). Hospital stays ranged from 4.0 to 12.1 and 5.0 to 12.8 days in the laparoscopic group and open group, respectively. Most of the studies provided low levels of evidence, mainly due to lack of blinding, randomization and correction of bias.
Conclusion: Totally laparoscopic aortoiliac surgery seems to be a feasible technique with unaffected mortality and trend toward benefits in hospital stay and possibly also in complication rates. The literature published this far is sparse and with inconsistent results. More randomized controlled trials are required before this method can be widely implemented.
