Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

6.1K
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.

Area of Science:

  • Gastroenterology
  • Interventional Endoscopy
  • Oncology

Background:

  • Acute cholecystitis in surgically unfit patients requires alternative drainage methods.
  • Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) is emerging as a viable option.
  • Limited data exist on fully covered self-expandable metal stents (FCSEMSs) for EUS-GBD, particularly in cancer patients.

Purpose of the Study:

  • To describe a simplified needle-to-stent EUS-GBD technique.
  • To evaluate the early clinical outcomes of this technique using specific EUS-GBD equipment.
  • To assess feasibility, safety, and efficacy in patients with acute cholecystitis secondary to malignant biliary obstruction.

Main Methods:

  • A simplified needle-to-stent EUS-GBD technique was applied.
  • A 19-gauge Franseen-tip FNB needle and a modified slim FCSEMS were utilized.
  • Consecutive patients with malignant biliary obstruction-induced acute cholecystitis were included.

Main Results:

  • Eighteen patients were included with a median follow-up of 6 months.
  • Technical and clinical success rates were both 100%.
  • No severe adverse events or 30-day mortality were observed; one patient had recurrent cholecystitis treated endoscopically.

Conclusions:

  • The simplified needle-to-stent EUS-GBD technique is feasible and safe.
  • This method demonstrates high technical and clinical success in managing acute cholecystitis in cancer patients.
  • It represents a promising therapeutic option for this challenging patient group.
