Nevada ERCP expert witnesses are gastroenterologists and interventional endoscopists who assess ERCP technique, peri-procedural decision-making, and post-procedure management. Many practice in Las Vegas and Reno hospital systems serving high-acuity, tourism-driven emergency volumes. They commonly evaluate indications, cannulation and sphincterotomy performance, sedation standards, infection control, and complications like pancreatitis or bile duct injury.
