Intraoperative cholangiography during laparoscopic cholecystectomy. Routine vs selective policy

Area of Science:

• Gastroenterology
• Surgical Imaging
• Radiology

Background:

• Laparoscopic cholecystectomy is a common surgical procedure.
• Intraoperative cholangiography (IOC) aids in detecting common bile duct stones.
• Evaluating the efficacy and efficiency of different IOC techniques is crucial.

Purpose of the Study:

• To audit the utility of routine intraoperative cholangiography in laparoscopic cholecystectomy.
• To compare the performance of portable, digitized C-arm fluorocholangiography with mobile X-ray and static films.
• To assess the impact of IOC on patient management.

Main Methods:

• A consecutive series of 496 patients undergoing laparoscopic cholecystectomy were audited.
• Intraoperative cholangiography was performed in 483 patients (97%).
• Data on procedure time, image quality, and diagnostic yield were collected and compared between imaging modalities.

Main Results:

• Portable, digitized C-arm fluorocholangiography significantly reduced procedure time and eliminated unsatisfactory radiological exposures.
• Repeat procedures were necessary in 22% of cases using mobile X-ray equipment.
• Unsuspected common bile duct stones were detected in 3.9% of patients (18/483).
• IOC identified 4 patients (0.8%) whose management would have been negatively impacted without it.

Conclusions:

• Routine intraoperative cholangiography is a valuable adjunct in laparoscopic cholecystectomy.
• Portable, digitized C-arm fluorocholangiography is a superior imaging modality for IOC.
• IOC facilitates the detection of common bile duct stones and influences patient management decisions.
