Interobserver variability in sphincter of Oddi manometry is minimal among experienced physicians. This study found high correlation and agreement in readings, suggesting reliable diagnostic interpretation.

Area of Science:

  • Gastroenterology
  • Medical diagnostics

Background:

  • Sphincter of Oddi manometry is a diagnostic tool for biliary and pancreatic disorders.
  • Assessing interobserver variability is crucial for standardizing manometric interpretations.

Purpose of the Study:

  • To quantify interobserver variability in reading sphincter of Oddi manometry tracings.
  • To evaluate the reliability of basal sphincter pressure measurements.

Main Methods:

  • Fifty sphincter of Oddi manometry tracings were analyzed by three experienced physicians.
  • Measurements included duodenal baseline pressure and basal sphincter pressure using two distinct methods.
  • Ninety station pull-throughs were assessed for correlation and agreement.

Main Results:

  • High correlation (coefficients > 0.9) was observed among observers for duodenal and basal sphincter pressures.
  • Agreement on normal (< or = 40 mm Hg) versus abnormal (> 40 mm Hg) basal sphincter pressure ranged from 82% to 90%.
  • Variability was greatest in patients with very high basal sphincter pressures.

Conclusions:

  • Interobserver variability in sphincter of Oddi manometry is minimal among experienced physicians.
  • Mean basal sphincter pressure is a clinically relevant parameter for diagnosis.
  • Standardized interpretation guidelines may further enhance diagnostic consistency.
