Cholangitis After Gallbladder Removal
Pathophysiology of Post-Cholecystectomy Cholangitis
- Cholangitis after cholecystectomy typically occurs due to obstruction of the common bile duct, most commonly from residual or recurrent stones, biliary strictures, or stent occlusion 3, 4
- Without a gallbladder, bile flows directly from the liver into the common bile duct and then into the duodenum, but this pathway can still become obstructed 1
- Recurrent cholangitis is a main consequence of bile duct stricture, which can develop after bile duct injury during cholecystectomy 2
Clinical Presentation
- Patients with post-cholecystectomy cholangitis typically present with fever, jaundice, right upper quadrant abdominal pain, and nausea and vomiting, consistent with Charcot's triad 1, 2, 5
Common Causes of Post-Cholecystectomy Cholangitis
- Biliary strictures can develop as a complication of cholecystectomy due to bile duct injury, leading to bile stasis and subsequent infection 1, 2
- Bile duct injury during surgery can lead to strictures and recurrent cholangitis 1, 2
Diagnosis
- Elevated liver function tests, particularly direct bilirubin, alkaline phosphatase (ALP), and gamma-glutamyl transpeptidase (GGT), and elevated white blood cell count indicating infection are common laboratory findings 2, 5
- Abdominal triphasic CT is recommended as first-line imaging to detect fluid collections and ductal dilation, while contrast-enhanced MRCP provides detailed visualization of the biliary tree 1, 2
- ERCP is both diagnostic and therapeutic 6
Management
- Prompt initiation of broad-spectrum antibiotics covering gram-negative aerobes and anaerobes is essential, with treatment adapted according to bile culture findings 7, 8
- ERCP with sphincterotomy and stone extraction is the first-line treatment for cholangitis due to bile duct stones, while ERCP with stent placement may be required for strictures 3, 6
Prevention
- Complete clearance of bile duct stones during initial treatment and proper surgical technique during cholecystectomy to avoid bile duct injury are crucial for prevention 1, 2, 3, 4
