Cardiovascular complications after common bile duct stone extractions

Area of Science:

• Gastroenterology
• Hepatobiliary Surgery
• Cardiovascular Medicine

Background:

• Common bile duct stone (CBDS) is a prevalent condition, particularly in aging populations.
• Treatment decisions for CBDS in elderly and frail patients necessitate careful evaluation of cardiovascular risks.
• Assessing treatment-related cardiovascular complications is crucial for managing CBDS.

Purpose of the Study:

• To compare the incidence of postoperative cardiovascular events in patients with CBDS undergoing different treatment strategies.
• To evaluate the safety of ERCP-only, cholecystectomy-only, and combined or sequential procedures for CBDS.
• To inform treatment decisions for CBDS, especially in high-risk patient groups.

Main Methods:

• Data from the Swedish National Quality Register for Cholecystectomy and ERCP (GallRiks) from 2006-2014 were analyzed.
• Included were ERCP and cholecystectomy procedures for confirmed or suspected CBDS.
• Postoperative cardiovascular events (myocardial infarct, pulmonary embolism, cerebrovascular disease) within 30 days were identified by cross-matching with the National Patient Register.

Main Results:

• A total of 23,591 patients underwent procedures for CBDS.
• Postoperative cardiovascular events occurred in 164 patients, and 225 patients died within 30 days.
• While univariable analysis suggested higher event rates with primary ERCP, multivariable analysis found no statistically significant difference in cardiovascular complications or 30-day mortality.

Conclusions:

• Both primary ERCP and cholecystectomy appear to be safe treatment options for CBDS.
• Additional research is required to develop robust guidelines for managing CBDS.
• The findings suggest that current treatment approaches for CBDS can be performed with acceptable safety profiles.
