An organised follow-up is required after bariatric surgery, but 50% of patients are lost to follow-up after 2 years. To design a large randomized clinical trial (RCT) comparing teleevaluations and teleconsultations to classical follow, aiming to prove that the quality of the follow-up is maintained and the patient-experience is improved, at a lower cost in people living far from the reference centre, this pilot study aims at describing the distribution of the collected criteria.


An organised follow-up is required after bariatric surgery, but 50% of patients are lost to follow-up after 2 years. This follow-up requires about 5 multi-professional evaluations during the first year. This can be cumbersome in patients living far from the reference centre and who may perceive the necessary time, cost and lost of income, and constraints as imbalanced. Teleevaluations and teleconsultations may solve this issue by replacing some of the classical evaluations (at 6 and 9 months). An RCT would be necessary, and a pilot study is proposed to describe the distribution of the judgment criteria.

This pilot study aims at describing all the parameters necessary to build an RCT, and involves the randomisation of operated patients recruited 3 months after surgery, in to groups. One will have the classical follow-up (venue and consultations at 6 and 9 months) the over will have teleevaluations and teleconsultations ; the parameters will be described at 12 months. The teleevaluation is either proposed as usual (a file is sent by secure mail) or by chatbot interaction. The consultation and the teleconsultation are based on the standard of care scenario.
