Abstract
Severe aortic stenosis (AS) poses the greatest risk for curative operation of the colon cancer and aortic valve replacement (AVR) is always preceded colon operation. However, the surgical approach should be considered by the patientʼs condition. We describe here the successful staged surgical treatment for severe AS and advanced colon cancer complicated by bowel obstruction. A 81-year-old man with dyspnea on exercise and watery diarrhea was found to have severe AS with AVA 0.61cm2 and sigmoid colon cancer complicated by bowel obstruction, which has a potential risk of aspiration pneumonia and prosthetic valve endocarditis following bacterial translocation. Colostomy was performed at first in order to release bowel obstruction, followed by AVR and low anterior resection of the rectum combined with resection of urinary bladder, seminal vesicles and prostate, 10 and 33 days later, respectively. Each postoperative course was uneventful. Preceding colostomy for release of bowel obstruction might be useful even in such a patient with concomitant severe AS.
