ObjectivesIn France, screening for esophageal varices (EVs) in cirrhotic patients with portal hypertension (PH) is performed by esophagogastroduodenoscopy (EGD). Though proven effective, EGD screening may be unpleasant for some patients. Our study sought to compare the cost-effectiveness of PillCam (Medtronic, Minneapolis, USA) esophageal capsule endoscopy (ECE), a less invasive test, versus EGD, for EV screening, from the perspective of the French national health system (NHS). In secondary objectives we compared the cost-effectiveness of ECE versus no screening for patients not compliant with EGD screening, and the cost-effectiveness of a screening strategy (ECE or EGD) versus no screening strategy at all. MethodsWe constructed a Markov model with data from the literature, applying it to two simulated cohorts of adult patients with cirrhosis and PH not previously screened for EVs. These patients were divided into EGD and ECE screening arms and tracked over a virtual 10-year period. Cost-effectiveness was defined as cost (in euros) per quality-adjusted life year (QALY). ResultsIn the base-case analysis, ECE is more expensive than EGD (€3,606 vs. €3,030) and less effective by 0.0098 QALY (5.2099 vs. 5.2197 QALYs). Probabilistic sensitivity analysis shows that ECE has only a 2.1% probability of being cost-effective at willingness-to-pay (WTP) of €30,000/QALY. ConclusionsAlthough patient compliance is apparently higher with ECE, it is not cost-effective at a WTP of €30,000/QALY and should not be considered in all patients with PH. Its cost-effectiveness should be reevaluated in the event of patient refusal of EGD follow-up. Public Interest SummaryEsophagogastroduodenoscopy (EGD) is gold standard to screen cirrhotic patients with portal hypertension for esophageal varices, but its unpleasantness lowers compliance. We evaluated the cost-effectiveness of a more acceptable alternative for patients: the esophageal capsule endoscopy (ECE).Our results show that screening by ECE is more expensive and less effective than by EGD from the perspective of the French national health system. It cannot be used as an alternative for all patients suffering from PH in France. Further investigations could be conducted to assess the effectiveness of ECE for the sub population of patients with PH who are totally refractory to EGD and may suffer from inadequate follow-up due to lack of screening.
