Thesis topic:

My thesis is based on a meta-research approach on interventional research in bariatric surgery, in the context of a rapidly expanding topic.
We have first conducted a mapping in order to inform researchers about past research efforts, research gaps, and overlap. Such mapping of all research efforts with a high level of evidence is needed to support researchers, while avoiding waste of resources. For this purpose, we systematically mapped all randomized controlled trials conducted since the first publication of a trial in the field of bariatric surgery in order to highlight research questions, outcomes and topics that have never been addressed before, despite a high volume of patients included in trials. In a second work, in the context of a constant evolution of surgical practices, we conducted a mapping of upcoming randomized controlled trials in bariatric surgery, in order to clarify the future of research in this field.
