Summary
Liver biopsy practices vary widely globally. This survey highlights significant differences in patient preparation, biopsy techniques, and post-procedure care among international and U.S. centers, informing new guidelines.
Area of Science:
- Hepatology
- Surgical Procedures
- Clinical Practice Guidelines
Background:
- Hospitals lack standardized guidelines for performing liver biopsies.
- Existing practices exhibit considerable variation nationally and internationally.
Purpose of the Study:
- To assess current liver biopsy practices in academic centers worldwide.
- To identify variations in patient preparation, technical aspects, and post-procedural care.
- To inform the revision of existing hospital guidelines for liver biopsy.
Main Methods:
- A survey of 500 international academic centers via multilingual questionnaires.
- Telephone survey of 85 U.S. centers.
- Assessment of pre-procedural tests, biopsy techniques (needle type, laparoscopy), and post-biopsy observation periods.
Main Results:
- Significant practice variations observed globally.
- Pre-biopsy bleeding time more common in Asian centers (73%) than U.S. centers (36%).
- Cutting needles preferred in Asia (61%), aspiration needles in the U.S. (74%).
- Laparoscopic liver biopsy common in Japan (30%), rare elsewhere.
- Post-biopsy observation varied, with most centers observing patients 10+ hours.
Conclusions:
- Current liver biopsy practices lack standardization across diverse geographic regions.
- The survey provides valuable insights into contemporary liver biopsy techniques and patient care.
- Findings will aid in redefining and establishing more consistent hospital guidelines for liver biopsy procedures.
