title: [Evidence based surgery: ethical and methodological aspects].
abstract: Recently, it has been said that surgical clinical research was of poor quality because there are few randomized controlled trials in this area. This type of experimental protocol comes up against many difficulties in surgery and may induce a conflict between scientific requirements and ethical principles. Improving the quality of observational studies with simple measures may palliate the problem. Moreover, keeping national or international registries provides very useful informations.
