Abstract

Background: No consensus exists on the optimal strategy for treatment of abdominal aortic aneurysm (AAA)associated with colorectal cancer (CRC). The purpose of this study was to evaluate the results of endovascular treatment of AAA with simultaneous resection of CRC. Methods: Twenty-two consecutive patients presenting with AAA associated with a CRC were treated by endovascular AAA exclusion and simultaneous CRC resection. Median diameter of the aneurysm was 6.5 cm (range, 4.8–8 cm). Two patients (9%)had grade I cancer, 5 patients (23%)grade II, 13 patients (59%)grade III, and 2 patients (9%)grade IV. The 2 surgical procedures were performed under the same general anesthesia. Aneurysm exclusion was achieved using an infrarenal aorto-bi-iliac endoprosthesis (13 patients)and using an aorto-bi-iliac endoprosthesis with suprarenal fixation (9 patients), with 1 patient receiving bilateral renal chimney stent implantation. In all cases, vascularization of the hypogastric arteries was preserved. After AAA exclusion, colic resection was carried out by laparotomy with right colectomy (7 patients)and anterior rectocolic resection (15 patients). In all patients, AAA exclusion was controlled by a computed tomographic angioscan (CTA)at 1 month and duplex ultrasound every 6 months, and at some later stage, it was through inclusion of CTA as part of oncology surveillance. The mean duration of follow-up was 42 months (10–120 months). The primary endpoint was composite and regrouped any death occurring during the first 30 days after procedures, any type I endoleak, any aortic reintervention, and any AAA-related mortality. Results: No patient died during the first 30 postoperative days, and no patient was lost to follow-up. No aortic endoprosthesis infection and no type I endoleak were observed. Five endoleaks arising from the lumbar arteries (n = 4)or from the inferior mesenteric artery (n = 1)were identified. As they were not associated with an increase of the AAA diameter >5 mm, they were not treated. 1 colic anastomotic leak and 2 incisional abscesses were successfully cured by local care only. Nine patients (41%)died of cancer evolution during the follow-up period. Conclusions: In this series, treatment of AAA and CRC during the same operative session yields results comparable to those observed when surgery is performed in 2 distinct operative sessions. Synchronous treatment reduced waiting time of colic resection. It may also shorten total hospitalization duration, although this last hypothesis is not supported by comparison with a control group.
