[Upper-abdominal ultrasonography and ERCP? (author's transl)]

    Summary

    Endoscopic retrograde cholangiopancreatography (ERCP) offers superior diagnostic accuracy for choledochal duct diseases compared to ultrasonography. Ultrasonography, however, excels in diagnosing pancreatic head cancer and gallstones.

    Area of Science:

    • Gastroenterology
    • Diagnostic Imaging
    • Surgical Pathology

    Background:

    • Upper-abdominal ultrasonography and endoscopic retrograde cholangiopancreatography (ERCP) are common diagnostic tools.
    • Comparative effectiveness of these imaging modalities for specific hepatobiliary and pancreatic conditions requires clarification.

    Purpose of the Study:

    • To compare the diagnostic accuracy of ERCP and ultrasonography.
    • To evaluate the efficacy of each method in detecting various abdominal pathologies, particularly those involving the choledochal duct.

    Main Methods:

    • A comparative study involving 134 patients undergoing both ultrasonography and ERCP.
    • Diagnostic assessments were compared with surgical or post-mortem findings in 62 patients.
    • Success rates were analyzed for specific conditions like choledocholithiasis, gallbladder carcinoma, pancreatic head carcinoma, and cholecystolithiasis.

    Main Results:

    • Ultrasonography optimally visualized organ structure in 70.2% of patients.
    • ERCP demonstrated a statistically significant advantage in diagnosing choledochal duct diseases, with 95% accuracy for choledocholithiasis and 85% for gallbladder carcinoma involving the duct.
    • Ultrasonography achieved higher accuracy for pancreatic head carcinoma (89%) and cholecystolithiasis (89%) compared to ERCP (56% and 74%, respectively).

    Conclusions:

    • ERCP is more effective for diagnosing choledochal duct pathologies, including stones and associated gallbladder cancer.
    • Ultrasonography is a more accurate initial diagnostic tool for pancreatic head carcinoma and uncomplicated gallstones.
