ERCP (Endoscopic Retrograde Cholangiopancreatography) is a minimally invasive procedure offering several significant advantages. The risk of infection is low due to the use of natural body orifices. When gallstones are removed from the bile ducts, widening the exit portion of the ducts reduces the likelihood of stone recurrence. In cases of bile duct strictures, stents eliminate the narrowing, significantly lowering the risk of bile duct obstruction. Furthermore, ERCP plays a critical role in the definitive diagnosis of bile duct and pancreatic tumors, and stent placements can notably improve patients' general condition and quality of life. This non-surgical procedure allows patients to recover more quickly and return to their daily activities sooner. Across a broad range of indications, it boasts a high success rate compared to other treatment methods.
