Transpapillary gallbladder biopsy is a safe and effective method for obtaining tissue samples for histopathologic diagnosis. This technique aids in diagnosing gallbladder diseases and guiding treatment decisions.

Area of Science:

  • Gastroenterology
  • Surgical Pathology
  • Diagnostic Endoscopy

Background:

  • Histopathologic diagnosis is crucial for gallbladder disease management.
  • Endoscopic biopsy is standard for gastrointestinal conditions.
  • The clinical utility of transpapillary gallbladder biopsy requires examination.

Purpose of the Study:

  • To evaluate the clinical usefulness of transpapillary gallbladder biopsy.
  • To identify potential challenges associated with this biopsy technique.

Main Methods:

  • Transpapillary gallbladder biopsy was performed on 9 patients.
  • A catheter sheath was inserted into the gallbladder via the transpapillary route without sphincterotomy.
  • Biopsy forceps were used to obtain specimens from the gallbladder lumen.

Main Results:

  • Sufficient specimens for diagnosis were obtained in 88.9% of cases (8/9).
  • Targeted specimens were achieved in 87.5% of successful biopsies (7/8).
  • Diagnostic accuracy for malignancy was 100% (2/2), and for benign disease was 83.3% (5/6), with no complications.

Conclusions:

  • Transpapillary gallbladder biopsy is a clinically valuable procedure.
  • It enables accurate histopathologic diagnosis, informing therapeutic choices.
  • The technique is safe and effective for gallbladder disease evaluation.
