Abstract:Effective pain control can significantly improve the quality of life of patients with end-stage cancer. Although some patients experience pain relief after using strong opioid drugs, there are still patients who cannot tolerate their adverse effects or need more other methods to relieve pain, such as endoscopic ultrasound-guided celiac plexus neurolysis (EUS-CPN). How to standardize and normalize the procedure of EUS-CPN has become an urgent matter. As EUS-CPN and its derivative technologies keep advancing, the understanding of clinical advantages, disadvantages, and complications of EUS‑CPN is also constantly updating. A large number of high-quality studies have been published by scholars at home and abroad to assist decision-making and standardization of the treatment procedure. This consensus, based on the existing domestic and international guidelines, summarized and updated the relevant research progress in recent years, and presented 8 clinical concerns and 22 recommendations in the form of questions and answers regarding clinical indications, intervention timing, technical selection, efficacy and complications, aiming to guide the standardized application of EUS-CPN.
