Colorectal cancer (CRC) with abdominal aortic aneurysm (AAA) is more common in the elderly population. Laparoscopic surgery (LS) for such complicated conditions has been performed, albeit the risks of AAA rupture during forceps manipulation under limited view.

An 89-year-old man had an endovascular aneurysm repair (EVAR) for AAA (Fig.  1a), but the aneurysm size gradually increased due to type II endoleak in the lumbar artery despite coil embolization (Fig.  1b). The maximum diameter of the aneurysm was 69 mm, and an open aneurysmorrhaphy along with lumbar artery ligation was planned to prevent rupture. Advanced descending colon cancer was detected preoperatively and diagnosed as UICC stage T3N0M0 (cStage IIa). The patient was at a high risk of colonic obstruction as the tumor had invaded the entire circumference of the colon (Fig.  1c). So, we decided to perform laparoscopic descending colectomy, prior to the aneurysm surgery.
