Endoscopy combined with endoscopic retrograde cholangiopancreatography is a unique tool providing a broad, precise yield of diagnostic information about diseases of the upper gastrointestinal tract. In the absence of gross anatomic disease, its diagnostic accuracy should exceed 90 per cent and risk be minuscule. The incidence of complications and, therefore, risk to the patient and proportional to the magnitude and remedial nature of the disease processes found. In the absence of diagnostic procedures for diseases of the biliary tree and pancreas that are riskless, the relationship of endoscopic retrograde cholangiopancreatography risk to diagnostic value and patient salvage emphasizes the value of endoscopy combined with endoscopic retrograde cholangiopancreatography as the diagnostic procedure of choice for patients with suspected disease of the biliary tract or pancreas. The unique value of endoscopic retrograde cholangiopancreatography in providing rapid visualization of diseases of the upper gastrointestinal tract mucosa combined with cholangiography and pancreatography is dramatized in the patient with upper abdominal pain syndrome with or without jaundice. In the face of a rapidly evolving illness and the potential need for early surgical intervention, barium studies are relatively contraindicated and have a poor diagnostic yield. By contrast, endoscopic retrograde cholangiopancreatography combined with endoscopy rapidly rules out, or, in the presence of disease of the upper gastrointestinal tract, permits the immediate use of subsequent diagnostic procedures. An experience with more than 1,000 procedures reveals that endoscopic retrograde cholangiopancreatography is an invaluable tool for the diagnosis and management of disease of the pancreas and biliary tract. |
