Abstract: | Background: Colic ischemia is a serious complication that can occur after abdominal aortic surgery. It has been described in two patients
after laparoscopic aortic surgery. The goal of the current experiment was to determine the feasibility of inferior mesenteric
artery (IMA) reimplantation during laparoscopic aortobifemoral bypass (LAFB).
Methods: Six piglets were submitted to the laparoscopic approach according to the ``apron' technique previously described. The infrarenal
aorta was clamped and an LAFB was performed using a dacron graft. The IMA was reimplanted in the body of the graft with a
running 5-0 polypropylene suture.
Results: Mean operation and dissection times were 282.5 min (range, 270–310 min) and 123 min (range, 110–140 min), respectively, with
a mean blood loss of 108 ml (range, 80–150 ml). Aortic clamping and anastomotic times were 123 min (range, 110–135 min) and
33 min (range, 24–45 min), respectively. The IMA reimplantation took 55 min (range, 45–70 min). At autopsy, all anastomoses
were patent with no stenosis nor leak.
Conclusion: Laparoscopic IMA reimplantation during laparoscopic aortobifemoral bypass is feasible.
