Background
The use of cholecystostomy (c-tube) in acute cholecystitis (AC) has increased yet there is limited evidence to guide surgical decision-making after placement. As a result, there is variability in the use and timing of cholecystectomy after c-tube. We aimed to describe patient characteristics, outcomes, and biliary-related utilization in those who did and did not have cholecystectomy after c-tube.
Methods
This is a retrospective cohort study (2007–2017) using the MarketScan® claims database of patients (18–63 years) with at least 3 months of follow-up (or death). ICD-9/10 and CPT codes were used to identify AC, c-tube placement, cholecystectomy and determine Elixhauser comorbidity index.
Results
A total of 2386 patients (47.5% female, mean age 52.5 [SD 9.9] years) with AC underwent c-tube with an 11.2% 90-day mortality. Among survivors, by three months 57% underwent cholecystectomy (mean 34.8 days [95% CI: 33.3–36.3]). Cholecystectomy after c-tube was more common in those with fewer comorbid conditions (mean 2.41 [95% CI: 2.26–2.56] vs 4.56 [95%CI: 4.36–4.76]). Biliary episodes prior to cholecystectomy occurred in 12.5% and were associated with eventual cholecystectomy (HR 1.49 [1.32–1.68]). Biliary-specific hospital and ICU days were similar between groups. Biliary-specific ED visits were more common among patients with cholecystectomy (mean 1.39 [95% CI: 1.29–1.48] vs 0.94 [95% CI: 0.85–1.03]).
Conclusion
More than half of patients treated with c-tube underwent cholecystectomy by three months—most within five weeks of AC diagnosis. The high frequency of use and short time to cholecystectomy after c-tube raises questions about potential overuse of c-tube in the initial period. Future work should aim to understand how patient experience and indication for c-tube influence the likelihood and timing of subsequent cholecystectomy.
