Abstract: Patients with biliopancreatic diseases following digestive tract reconstruction present challenges for endoscopic retrograde cholangiopancreatography (ERCP) due to postsurgical anatomical alterations, which significantly increases procedural difficulty and the risk of complica-tions. To standardize the practice of ERCP in this patient population and enhance its safety and efficacy, based on evidence‑based medicine, Branch of Biliary Surgery of Chinese Society of Surgery of Chinese Medical Association, Working Group of Biliary Surgeons of Chinese College of Surgeons of Chinese Medical Doctor Association, and Editorial Board of Chinese Journal of Digestive Surgery organize experts in related fields and formulate Expert consensus on ERCP after digestive tract reconstruction(2026 edition), which addresses key clinical issues, including indication assessment, selection of technical approaches, prevention and management of complications, and the role of multi-disciplinary collaboration. The consensus aims to mitigate procedural risks, improve success rates, and ultimately enhance patient quality of life through standardized operational protocols, optimized technical strategies, and strengthened peri‑procedural management.
