Postoperative ERCP as proxy for clinically significant retained stones in a population-based cohort?

Area of Science:

• Gastroenterology
• Surgical Outcomes
• Biliary System Diseases

Background:

• Retained common bile duct stones (CBDS) after cholecystectomy require accurate identification for proper management.
• Estimating the incidence of retained CBDS necessitates tracking both conservatively managed and endoscopically treated cases.
• The study investigates the utility of endoscopic retrograde cholangiopancreatography (ERCP) as an indicator for retained CBDS in a real-world setting.

Purpose of the Study:

• To determine the rate of retained common bile duct stones (CBDS) following cholecystectomy.
• To evaluate the effectiveness of endoscopic retrograde cholangiopancreatography (ERCP) as a proxy for identifying retained CBDS.
• To assess ERCP's performance in a population-based setting for managing gallstone surgery patients.

Main Methods:

• Data sourced from the Swedish Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography Register (GallRiks) (2015-2020).
• Analysis included patients undergoing cholecystectomy with suspected CBDS at South General Hospital, Stockholm.
• Medical records were reviewed to identify retained CBDS events and compare them with ERCP data.

Main Results:

• 47.2% of patients had common bile duct stones (CBDS) on intraoperative cholangiography.
• During follow-up, 33 of 182 patients showed signs of retained CBDS.
• Of those with retained CBDS, 24 underwent ERCP, while 9 were identified through medical records alone.

Conclusions:

• Postoperative endoscopic retrograde cholangiopancreatography (ERCP) is a valid proxy for detecting retained stones after surgery.
• ERCP can serve as a valuable quality measure for managing patients with suspected common bile duct stones (CBDS) undergoing gallstone surgery.
