A new technique for laparoscopic aortobifemoral grafting in occlusive aortoiliac disease.
OBJECTIVE
This article describes an original laparoscopic technique that allows performance of aortobifemoral bypass grafting.


METHODS
The technique described is the result of 6 years of in vitro and animal experimentation. It also represents the end result of prior clinical research with laparoscopy-assisted aortoiliac surgery and totally laparoscopic retroperitoneal aortobifemoral bypass grafting. The technique consists of the creation of a flap of retroperitoneum that is used to separate the intraperitoneal organs from the content of the retroperitoneal cavity. Surgery can then be conducted with no intrusion of any intraabdominal organ into the operative field. Another advantage is that the pneumoperitoneum is equally distributed among the two cavities. A conventional aortobifemoral bypass procedure is then performed with laparoscopic instrumentation.


RESULTS
The described technique has been performed in three patients to date. The patients' intraoperative blood loss did not exceed 500 ml, and no complication arose. The intraoperative need for crystalloids was of the order of 3 L (almost half the quantity usually administered). The patients' analgesia requirement was low in these patients, and return to walking was rapid. They were sent home between the fourth and sixth postoperative days.


CONCLUSIONS
The innovative technique described here is safe and appears to ease the patient's postoperative course. Data recovered from the multicenter study, which is now in its preliminary phase, should help answer numerous questions. We expect the procedure to be reproducible in other university centers that are participating in the trial.
