New study could change how doctors treat blocked colon cancer
NCT ID NCT04450758
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at two ways to treat colon cancer that has blocked the bowel. One option is emergency surgery to remove the cancer right away. The other is to first place a stent (a small tube) or create a stoma (an opening in the belly) to relieve the blockage, and then do surgery later. The goal is to see which approach leads to fewer complications and better long-term survival. About 1,000 adults with blocked colon cancer will take part.
