The techniques for endoscopic diagnosis and treatment of biliary and pancreatic diseases mainly include endoscopic retrograde cholangiopancreatography and endoscopic ultrasonography,which have achieved great progress in recent years.Meanwhile,new techniques including combined therapy with endoscopy and laparoscopy and natural orifice transluminal endoscopic surgery have gradually been applied in clinical practice.In the future,it is necessary to cultivate interdisciplinary experts in the field of endoscopy who master various endoscopic techniques and integrated talents with experience in both transluminal operation and gastrointestinal surgery outside lumens.At present,there are still controversies over the application of new techniques in the treatment of biliary and pancreatic diseases.The diagnosis and treatment of biliary and pancreatic diseases can be further improved by promoting the application of biliary and pancreatic endoscopy and standardization,accumulating experience and improving devices,evaluating clinical research,and promoting the bench-to-bedside translation of new techniques.
