Background/Aim:
A concise surgical strategy for concomitant abdominal aortic aneurysm (AAA) and operable gastric cancer remains unknown. We assessed a one-stage procedure that included endovascular abdominal aortic aneurysm repair (EVAR) and gastric resection.
Patients And Methods:
Forteen patients who underwent surgery for an infrarenal AAA and gastric cancer between 1990 and 2012 were retrospectively reviewed. Demographic characteristics, aneurysm size, comorbid conditions, length of postoperative hospital stay, complications within 30 days of surgery, and survival in patients in EVAR (n=4) were compared against patients who had an open AAA repair (n=10).
Results:
Demographic characteristics, aneurysm size, and comorbid conditions were similar in the EVAR and open-AAA-repair group. The mean length of hospitalization was significantly shorter in the EVAR group (15.2 days vs. 34.9 days; p=0.005), and the rate of postoperative complications was significantly lower (p<0.05). The overall survival rates in the EVAR and open-AAA-repair groups were, respectively, 100% and 80% at 1 year and 75% and 60% at 3 years; the differences between groups were not significant (p=0.788).
Conclusion:
In patients with concomitant AAA and gastric cancer who are eligible for EVAR, use of a one-stage procedure including EVAR and gastric resection is feasible.
