Background. Roux-en-Y gastric bypass (RYGB) is considered an effective and well-tolerated surgical procedure. In this retrospective study, we critically assessed efficacy and negative personal experiences (NPEs) after RYGB with a self-administered questionnaire (SAQ). Methods. This questionnaire study included 404 patients who had undergone RYGB. Analysis was performed using data from medical records, referral letters, and SAQs at an average of 33 months after procedure. We evaluated the occurrence of hypertension, CPEP use and type 2 diabetes mellitus (T2DM), the amount of excess weight loss, degree of satisfaction and negative personal experiences (NPEs) related to the procedure, and adherence to a dedicated life style program and (non)attendance to followup. consults after surgery. Results. 42.3% of all SAQs were evaluable for analysis. T2DM remained similar, while hypertension and continuous positive airway pressure (CPAP) use decreased significantly; excess weight loss of ≥40% was reported in 69% and of <40% in 19%, a significant improvement. Absolute weight gain was reported in 10.5%, fatigue in 44.4%, dysphagia in 11.6%, and other NPEs in 7.6%. Dissatisfaction over weight loss was reported in 9.4%. Mean number of follow-up visits was 9.6 per respondent, while nonattendance of any follow-up visit consults occurred in 1.8%. Conclusions. The use of post-RYGB SAQs provided evaluable data in 42.3%. Treatment failure after RYGB appears to be relevant, encouraging the use of SAQ studies in large cohorts.
