Cost-effectiveness of operative cholangiography
American Journal of Surgery
|January 1, 1979
Summary
Routine intraoperative cholangiography for gallstones is often inaccurate and costly. Selective use based on clinical indications, excluding small stones, improves diagnostic accuracy for bile duct disease.
Area of Science:
- Gastroenterology
- Surgical Diagnostics
- Biliary System Imaging
Background:
- Intraoperative cholangiography is a diagnostic tool used during cholecystectomy.
- Its routine use and indications for patients with small gallstones are debated.
- Assessing the diagnostic accuracy and cost-effectiveness of this procedure is crucial.
Purpose of the Study:
- To evaluate the diagnostic accuracy of intraoperative cholangiography.
- To determine the cost-effectiveness of routine versus selective use of cholangiography.
- To identify optimal indications for intraoperative cholangiography during cholecystectomy.
Main Methods:
- Retrospective review of 377 intraoperative cholangiograms performed between 1971 and 1975.
- Analysis of cholangiogram results compared to common bile duct exploration findings.
- Evaluation of cost and operative time associated with the procedure.
Main Results:
- Routine cholangiography or use for small stones had a low positive rate (0.9%) and high false-positive rate (38%).
- Selective use in patients with clinical indications (excluding small stones) showed 81% accuracy.
- The procedure increased operative time by 31 minutes and incurred significant costs.
Conclusions:
- Intraoperative cholangiography is most effective when used selectively based on specific clinical indications.
- Routine use or use for small gallstones is not cost-effective and yields limited diagnostic value.
- Standard criteria for common bile duct exploration, excluding small calculi, should guide cholangiography use.
