Long-term Outcomes of Symptomatic Gallbladder Sludge

Area of Science:

• Gastroenterology
• Hepatobiliary Medicine
• Diagnostic Imaging

Background:

• Gallbladder (GB) sludge is a common finding, but its long-term implications for symptomatic patients are not well-defined.
• Understanding the risk of subsequent biliary events is crucial for clinical management.

Purpose of the Study:

• To investigate the long-term outcomes of symptomatic gallbladder sludge.
• To determine the incidence of subsequent biliary events in patients with and without GB sludge.

Main Methods:

• Retrospective review of a prospectively maintained database of patients with typical biliary pain and ultrasonography findings.
• Exclusion of patients with gallstones.
• Comparison of biliary event rates (acute cholecystitis, cholangitis, pancreatitis) between GB sludge and non-GB sludge cohorts.

Main Results:

• Patients with symptomatic GB sludge had a significantly higher 5-year cumulative biliary event rate (33.9% vs. 15.8%, P=0.021).
• The hazard ratio for subsequent biliary events was 2.573 in the GB sludge group (P=0.025).
• While not statistically significant, individual event rates were higher in the sludge group; cholecystectomy appeared to reduce event frequency (12.5% vs. 40.4%).

Conclusions:

• Symptomatic gallbladder sludge is associated with an increased risk of subsequent biliary events.
• Gallbladder sludge should be considered a potential cause of biliary pathology.
• Cholecystectomy may serve as a preventative measure against recurrent biliary events in these patients.
