We retrospectively reviewed 13 patients in whom endoscopic stenting for colonic stenosis due to extracolonic cancers(non- CRC group)was attempted between July 2012 and January 2018. There were 5 men and 8 women, with a median age of 69 years. Primary malignancies causing colonic stenosis were gastric cancer(n=4), cholangiocarcinoma(n=2), pancreatic cancer(n=2), lung cancer(n=2), uterine cancer(n=2), and ovarian cancer(n=1). The non-CRC group patients demonstrated a significantly lower technical success rate than those who received palliative stents for colonic stenosis for primary colorectal cancer(n=51)(69% vs 98%, p<0.01). In addition, the non-CRC group patients(n=13)also demonstrated a significantly lower technical success rate(69% vs 99%, pp<0.01)than those who received stents aiming to subsequently undergo a bridge to surgery. Nonetheless, colorectal stenting for extracolonic malignancies appears to be a minimally invasive treatment and could offer patients rapid relief. Thus, it could be an effective alternative to some palliative therapies.
