Endoscopic Procedures V: ERCP

1.9K
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.

Urinary Tract Calculi VI: Surgical Management

222
Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Area of Science:

  • Gastroenterology
  • Endoscopic Surgery
  • Medical Devices

Background:

  • Pancreaticobiliary stone extraction via ERCP is often difficult in cases of limited working space, ductal irregularity, or strictures.
  • Existing methods may be insufficient for complex anatomical challenges.

Purpose of the Study:

  • To demonstrate the efficacy of miniature ductoscopic grasping and retrieval devices for pancreaticobiliary stone extraction.
  • To showcase successful stone removal in challenging anatomical scenarios.

Main Methods:

  • Utilized miniature retrieval baskets, snares, and forceps through a cholangioscope/pancreatoscope.
  • Applied these devices for stone extraction in intrahepatic, cystic, stenotic, tortuous pancreatic ducts, and pancreatic side branches.

Main Results:

  • Successful stone extraction was achieved in all five reported cases.
  • No adverse events were reported during the procedures.

Conclusions:

  • Miniature grasping accessories are effective for retrieving pancreaticobiliary stones in difficult anatomical situations.
  • These devices represent a significant advancement in the therapeutic options for treating pancreaticobiliary stones.
