Difficulties during endoscopic retrograde cholangiopancreatography (ERCP) were overcome using forceps to increase endoscope rigidity. This simple, equipment-free technique facilitated duodenal intubation for bile duct stone treatment.
Area of Science:
- Gastroenterology
- Endoscopic Procedures
Background:
- Endoscopic retrograde cholangiopancreatography (ERCP) is crucial for managing biliary and pancreatic diseases.
- Duodenal intubation can be challenging in patients with anatomical variations like cascade stomach.
- Standard ERCP maneuvers may fail to achieve duodenal access in difficult cases.
