Endoscopic retrograde cholangiopancreatography (ERCP) is complex and prone to pitfalls. Understanding normal anatomic variants and imaging artifacts is crucial for effective ERCP performance and interpretation.

Area of Science:

  • Gastroenterology
  • Diagnostic Imaging
  • Endoscopy

Background:

  • Endoscopic retrograde cholangiopancreatography (ERCP) is a complex diagnostic procedure.
  • ERCP requires significant manual dexterity, technical skill, and accurate image interpretation.
  • The procedure is associated with numerous potential pitfalls.

Purpose of the Study:

  • To highlight common pitfalls in ERCP.
  • To discuss the role of normal anatomic variants and artifacts in ERCP complications.
  • To provide guidance for effective ERCP performance and interpretation.

Main Methods:

  • Retrospective review of approximately 1300 ERCP studies.
  • Analysis of studies performed at a single center over a 2-year period.
  • Identification and illustration of common anatomic variants and imaging artifacts.

Main Results:

  • Anatomic variants and examination artifacts are significant contributors to ERCP pitfalls.
  • Knowledge of these variations is essential for successful ERCP.
  • Illustrations aid in understanding and avoiding common errors.

Conclusions:

  • Familiarity with pancreatic and biliary variants is necessary for ERCP success.
  • Awareness of imaging artifacts improves ERCP accuracy.
  • This review provides a valuable resource for clinicians performing and interpreting ERCP.
