Core Tip
Core Tip: This editorial discusses the mechanisms and techniques involved in the placement of self-expandable metal stents (SEMS) in patients with acute colonic obstruction. It highlights recent advancements in endoscopic stenting methods, including fluoroscopy-free techniques and the use of slim and ultrathin endoscopes. The editorial covers the choice of stent design, technical success rates, common complications, and long-term outcomes of SEMS placement. It also explores future directions, including the optimization of stent designs and the timing for subsequent surgery. SEMS represents a significant advancement in the management of acute colonic obstruction, offering a safe and effective alternative to emergency surgery.
