Management of Cholecystitis with Biliary Stent: Sequence of Procedures
For patients with cholecystitis who have had a biliary stent placed and are scheduled to return after 6 weeks, the stent should be removed first followed by cholecystectomy during the same procedure. 1
Rationale for Stent Removal First
- Biliary stents used for treating dominant stricture or cholecystitis should be removed 1-2 weeks following insertion, with longer periods increasing risk of complications 1
- Short-term use of biliary stents followed by further endoscopy or surgery is strongly recommended by guidelines to ensure adequate biliary drainage 1
- Stents tend to clog rapidly in patients, with studies showing complications developing in up to 40% of patients during the period with stents in situ 2
- Acute cholangitis can develop secondary to a clogged biliary stent, particularly when left in place beyond the recommended timeframe 3
Procedural Approach
- The optimal approach is to first perform ERCP for stent removal, followed immediately by cholecystectomy during the same anesthetic session 1
- If same-session procedures are not feasible, stent removal should still precede cholecystectomy to:
Evidence Supporting Early Intervention
- Meta-analysis data shows that mortality is higher in patients with a "wait and see" approach compared to those who undergo prophylactic cholecystectomy after biliary drainage (14.1% vs 7.9%) 1
- Secondary endpoints of recurrent pain, jaundice, and cholangitis are also significantly more common in patients with delayed intervention 1
- Prophylactic cholecystectomy after common bile duct stone extraction reduces the incidence of subsequent cholecystitis 1
Complications of Delayed Stent Removal
- Stent clogging can occur as early as 1-2 months after placement, leading to recurrent cholangitis 3
- Studies show that when referring physicians do not adhere to treatment protocols for timely stent exchange, up to 70% of patients require nonelective intervention for jaundice and/or cholangitis 2
- Biliary stent placement alone without definitive treatment results in a high rate of symptom recurrence (up to 50%) 4
Special Considerations
- In high-risk surgical patients (ASA class 3-4), a more cautious approach may be warranted, but the stent should still be removed first to assess biliary drainage 1
- For patients with prohibitive surgical risk, biliary sphincterotomy and endoscopic duct clearance alone may be considered as an alternative to cholecystectomy 1
- If the patient has coagulopathy, endoscopic approaches are preferred over percutaneous methods due to lower bleeding risk 1
By removing the stent first and proceeding with cholecystectomy, you minimize the risk of stent-related complications while providing definitive treatment for cholecystitis in a timely manner.
