Selective per-operative cholangiography and scoring method for selection.

Area of Science:

• Gastroenterology
• Surgical Innovation
• Diagnostic Imaging

Background:

• Gallstones are a common condition requiring surgical intervention.
• Per-operative cholangiography (PC) is frequently used during cholecystectomy to detect common bile duct stones.
• The necessity and efficiency of routine PC are debated.

Purpose of the Study:

• To evaluate a selective policy for per-operative cholangiography (PC) in patients undergoing elective cholecystectomy for gall stones.
• To assess the utility of a scoring method in guiding the decision for PC.

Main Methods:

• A prospective clinical study of 210 consecutive gallstone cases.
• Implementation of a scoring method based on pre- and per-operative surgical criteria to determine PC necessity.
• Routine PC was initially performed, with data analyzed retrospectively based on the scoring method.

Main Results:

• PC was indicated in only 30.5% of cases based on the selective policy.
• The scoring method correctly identified 18 out of 20 abnormal cholangiograms, with a 0.95% false positive rate.
• A small, asymptomatic common bile duct stone was missed in 0.47% of cases not indicated for routine PC.
• Routine PC could have been avoided in 69.5% of patients, potentially missing only asymptomatic common bile duct stones.

Conclusions:

• Routine per-operative cholangiography is not always necessary for patients with gall stones.
• A selective policy for PC, guided by a scoring method, can effectively reduce unnecessary X-ray exposure.
• The scoring method serves as a useful guide for selecting patients who would benefit from PC.
