Study Overview
Brief Summary
The hypothesis is that the Alfapump® strategy would be more effective in terms of QALYs generated , and that the cost of Alfapump® device and its implantation will be totally or partially offset by the reduction in the number of evacuating parentheses performed and the reduction in the number of complications in patients with refractory ascites awaiting liver transplantation or not. On the other hand, given the difference in the clinical profiles of these two populations (whether or not they are awaiting transplantation), these two populations will be study separately
Evaluation of the medical-economic impact at 1 year of the two therapeutic strategies: implantation of Alfapump® versus repeated evacuating paracentesis in cirrhotic patients with refractory ascites without scheduled liver transplantation.
Detailed Description
Refractory ascites is one of the complications associated with portal hypertension in the cirrhotic patient. To date, its treatment consists of evacuating punctures, performed in day hospitalisation, whose frequency is adapted to the rate of ascites synthetis. Paracentesis, which does not affect the mechanisms of ascites formation, contributes to protein catabolism and undernutrition. They also have an inconvenience linked to the gesture, making frequent hospital stays necessary. For all these reasons, the patient's quality of life is diminished. The Alfapump® system is a new method for the treatment of refractory ascites. It is a completely internalized medical device, implanted under the skin, which mobilizes ascites from the peritoneal cavity to the bladder, where ascites is eliminated by urinary tract.
