Summary
This study introduces a novel suprapapillary needle puncture technique for biliary access during ERCP, demonstrating high success and minimal complications. The method proves safe for diagnostic and therapeutic interventions, with no significant laboratory changes observed.
Area of Science:
- Gastroenterology
- Endoscopic Procedures
- Biliary Interventions
Background:
- Biliary cannulation for ERCP can be technically challenging.
- Papillotomy, often required, carries risks of pancreatitis and perforation.
Purpose of the Study:
- To evaluate a new suprapapillary needle puncture technique for biliary access.
- To assess the safety and laboratory profile of this novel ERCP approach.
Main Methods:
- 30 patients underwent ERCP using the suprapapillary puncture technique.
- Serum amylase, lipase, and C-reactive protein (C-RP) were monitored pre- and post-procedure.
- Patients were followed for 60 days, with laboratory parameters analyzed statistically.
Main Results:
- The suprapapillary puncture technique achieved 93.4% success.
- No significant changes in laboratory profiles (amylase, lipase, C-RP) were observed.
- Complications were minimal, including one case of mild hemorrhage and two retroduodenal perforations.
Conclusions:
- Suprapapillary puncture is a safe and effective method for ERCP.
- The technique allows diagnostic and therapeutic interventions with minimal impact on laboratory markers.
- Fistula dilation ensures patency without complications, and papilla appearance is normal post-procedure.

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.

01:19Bile
Bile is a crucial bodily fluid, characterized by its yellow-green color and alkaline nature. Produced in the liver, it is transported through the common hepatic duct into either the cystic duct, leading to the gallbladder, or directly into the common bile duct. The flow of bile is regulated by the sphincter of Oddi located at the entrance of the duodenum. When this sphincter is closed, bile is redirected to the gallbladder for storage and concentration.
