Endoscopic Procedures V: ERCP

2025
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session. Patient...

Learning new stimulus-response associations engages a wide range of neural processes which are ultimately reflected in changing spike output of individual neurons. Here we describe a behavioral protocol allowing for the continuous registration of single-neuron activity while animals acquire, extinguish, and reacquire a conditioned response within a single experimental session.

The use of the masseteric nerve as donor nerve represents a single-stage alternative to the criterion standard two-stage procedure of cross-facial nerve grafting and free muscle transfer in facial paralysis. We provide a detailed description to safely perform this technique with a gracilis muscle transfer and discuss indications and limitations.

Tissue-engineered implants for reconstructive surgery rarely progress beyond preclinical trials due to laborious ex vivo culturing, which includes complex and expensive scaffold components. Here, we present a single-staged procedure designed for urinary diversion with an accessible collagen-based tubular scaffold containing autologous micrografts.
FAQs
The major duodenal papilla serves as the access point for cannulating the bile or pancreatic duct. After contrast is injected, fluoroscopy displays the ductal anatomy and helps reveal abnormalities that can be addressed during the same session. This combined visualization and access allows clinicians to move directly from evaluation to an appropriate therapeutic step when indicated.
Single-stage ERCP can combine duct evaluation and treatment without requiring a separate endoscopic session for the therapeutic portion. When findings support intervention, clinicians may proceed immediately with measures such as stone extraction or stent placement. This approach can reduce repeat procedures, although it still requires careful selection and monitoring.
Patient selection is important because the procedure can produce clinically significant complications, including pancreatitis, bleeding, infection, or perforation. Monitoring helps clinicians identify these problems after the examination and any treatment have been completed. The need for this oversight reflects the balance between the convenience of one session and the risks of invasive ductal intervention.
The appropriate intervention depends on the abnormality identified during contrast imaging and fluoroscopic examination. Available therapeutic steps described for single-stage ERCP include sphincterotomy, stone extraction, and stent placement. Because these options follow the diagnostic portion immediately, the session can address a demonstrated duct problem rather than stopping after visualization alone.
Common bile duct stones and biliary obstruction are primary indications. Clinicians may also use the procedure for strictures and selected duct leaks, where ductal evaluation can be followed by treatment during the same session. These applications make single-stage ERCP relevant when both identifying the source of a duct abnormality and addressing it are clinically necessary.
The intended outcome is diagnostic clarification followed, when appropriate, by immediate treatment of the ductal abnormality. Clinicians must also watch for pancreatitis, bleeding, infection, and perforation because these complications can occur after the procedure or its therapeutic maneuvers. Careful monitoring therefore remains necessary even when evaluation and treatment are completed in one session.
