Summary
Intraoperative choledochoscopy aids biliary surgery by visualizing bile ducts. This endoscopic examination, particularly for ductal stones, improves surgical outcomes and reduces overlooked stones.
Area of Science:
- Biliary surgery
- Gastroenterology
- Surgical endoscopy
Background:
- Intraoperative choledochoscopy is a valuable tool in managing biliary tract diseases.
- Different instruments (flexible and rigid) are suited for specific parts of the biliary system.
Purpose of the Study:
- To report the experience with 776 intraoperative choledochoscopies.
- To evaluate the indications and outcomes of this procedure.
Main Methods:
- Performed 776 intraoperative choledochoscopies using flexible and rigid instruments.
- Utilized supraduodenal choledochotomy for access in most cases.
Main Results:
- Ductal stones were identified in 348 patients (44.8%).
- 10 patients (2.8%) had overlooked stones.
- Indications included equivocal cholangiograms, ductal stones, and obstructive tumors.
Conclusions:
- Intraoperative choledochoscopy is effective for diagnosing and treating biliary conditions.
- Careful examination is crucial to minimize overlooked stones.
