Part 1: Unlocking ERCP: The Minimally Invasive "Golden Key" for Hepatobiliary and Pancreatic Diseases

In recent years, the incidence of digestive system diseases has been on a steady rise globally, particularly in the field of hepatobiliary and pancreatic disorders. According to the World Health Organization (WHO) and the Global Burden of Disease Study (GBD), as of 2024, over 2 million deaths worldwide were attributed to hepatobiliary and pancreatic conditions, with the incidence continuing to climb.

Common conditions include gallstones, acute cholangitis, chronic pancreatitis, cholangiocarcinoma, and pancreatic cancer. These diseases manifest with symptoms such as jaundice, severe abdominal pain, nausea, vomiting, and impaired digestive function, significantly impacting patients' quality of life and, if left untreated, potentially becoming life-threatening. The rising prevalence of these conditions can be attributed to a variety of factors, including high-fat diets, sedentary lifestyles, obesity, metabolic syndromes (such as diabetes), chronic alcohol consumption, viral infections (like hepatitis B and C), and genetic predispositions. Additionally, the aging population has contributed to the growing number of cases, as the elderly are more prone to gallstone formation and inflammation due to declining biliary function.

Against this backdrop, Endoscopic Retrograde Cholangiopancreatography (ERCP) has emerged as a critical minimally invasive technique for the diagnosis and treatment of hepatobiliary and pancreatic diseases. ERCP combines endoscopy and X-ray imaging to directly visualize the bile and pancreatic ducts, enabling precise interventions. 

Its primary applications include:  

u Removal of Bile Duct Stones: ERCP allows for the direct extraction of stones from the bile duct, alleviating obstruction-induced jaundice and infections.  

u Management of Strictures: Inflammatory or tumor-related bile duct strictures can be addressed by placing stents or performing dilation to restore bile flow.  

u Tumor Diagnosis: Paired with biopsy techniques, ERCP facilitates the early detection of cholangiocarcinoma or pancreatic cancer, providing a window for timely treatment.  

u Treatment of Bile Leaks: For postoperative or traumatic bile leaks, ERCP can effectively manage the condition through drainage or stent placement.

Compared to traditional open surgery, ERCP offers significant advantages:

ü Minimal trauma (access via the mouth)

ü Faster recovery (patients typically discharge within 1-2 days post-procedure)

ü Lower rate of complications (such as infection or bleeding risks, which are far less than those of open surgery)

ü Furthermore, ERCP allows for simultaneous diagnosis and treatment in a single procedure, sparing patients the need for multiple interventions.

Statistics show that ERCP boasts a success rate of over 90%, making it the preferred choice for treating hepatobiliary and pancreatic conditions.

To provide a clearer understanding of the ERCP procedure, here is a 2-minute video explanation of the process:

As seen in the video, ERCP demands high precision, flexibility, and reliability from the instruments used. The procedure navigates the narrow and complex biliary environment, where any misstep could lead to complications like bile duct perforation or infection. In the next article, we will continue to explain the role played by the disposable choledochoscope as one of the most core surgical instruments in ERCP.
