Cost-effectiveness of Early Surgery Versus Endoscopy-first Approach for Painful Chronic Pancreatitis in the ESCAPE Trial.

OBJECTIVE

Economic evaluation of early surgery compared to the endoscopy-first approach in CP.

BACKGROUND

In patients with painful CP and a dilated main pancreatic duct, early surgery, as compared with an endoscopy-first approach, leads to more pain reduction with fewer interventions. However, it is unknown if early surgery is more cost-effective than the endoscopy-first approach.

METHODS

The multicenter Dutch ESCAPE trial randomized patients with CP and a dilated main pancreatic duct between early surgery (surgery within 6 weeks) or the endoscopy-first approach in 30 centers (April 2011-September 2016). Healthcare utilization was prospectively recorded up to 18 months after randomization. Unit costs of resources were determined, and cost-effectiveness and cost-utility analyses were performed from societal and healthcare perspectives. Primary outcomes were the costs per unit decrease on the Izbicki pain score and per gained quality-adjusted life-year.

RESULTS

In total, 88 patients were included in the analysis, with 44 patients randomized to each group. Total costs were lower in the early surgery group but did not reach statistical significance (mean difference €-4,815 (95% bias-corrected and accelerated confidence interval €-13,113 to €3411; P = 0.25). Early surgery had a probability percentage of 88.4% of being more cost-effective than the endoscopy-first approach at a willingness-to-pay threshold of €0 per day per unit decrease on the Izbicki pain score. The probability percentage per additional gained quality-adjusted life-year was 75.7% at a willingness-to-pay threshold of €50,000.

CONCLUSION

In patients with painful CP and a dilated main pancreatic duct, early surgery was more cost-effective than the endoscopy-first approach.
