Pseudostone at ERCP due to juxtapapillary diverticulum.

D J Lintott, W S Ruddell, A T Axon

    Clinical Radiology
    |March 1, 1981
    PubMed
    Summary

    Juxtapapillary duodenal diverticula can mimic gallstones on ERCP imaging. Recognizing these pseudostructures prevents unnecessary surgical intervention in patients with clear bile ducts.

    Area of Science:

    • Gastroenterology
    • Diagnostic Imaging

    Background:

    • Juxtapapillary duodenal diverticula are anatomical variations.
    • These diverticula are frequently observed during endoscopic retrograde cholangiopancreatography (ERCP).

    Purpose of the Study:

    • To highlight the potential for juxtapapillary duodenal diverticula to be misidentified as stones.
    • To emphasize the importance of recognizing this pseudostone appearance to avoid misdiagnosis.

    Main Methods:

    • Review of ERCP findings in patients with juxtapapillary duodenal diverticula.
    • Analysis of cholangiographic images demonstrating the characteristic appearance.

    Main Results:

    • Juxtapapillary diverticula create a distinct "pseudostone" appearance on retrograde cholangiograms.
    • This appearance can be mistaken for actual stones in the common bile duct.

    Conclusions:

    • Accurate identification of juxtapapillary duodenal diverticula is crucial.
    • Failure to recognize these diverticula can lead to unnecessary and inappropriate surgical procedures.
