Registered outcomes5
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Percentage of Total Weight Loss (%TWL) After Revisional Bariatric Surgery | 6 months, 12 months and 3 years after revisional surgery | Weight loss after revision expressed as the percentage of total weight loss (%TWL), calculated as: %TWL = \[(body weight before revision - body weight at follow-up) / body weight before revision\] x 100. Body weight is measured in kilograms (kg) on a clinic weighing scale before revision and at each follow-up visit, and recorded in the patient's follow-up file. Unit of measure: percentage (%) of pre-revision body weight. |
| Primary | Percentage of Excess Weight Loss (%EWL) After Revisional Bariatric Surgery | 6 months, 12 months and 3 years after revisional surgery | Weight loss after revision expressed as the percentage of excess weight loss (%EWL), calculated as: %EWL = \[(body weight before revision - body weight at follow-up) / (body weight before revision - ideal body weight)\] x 100, where ideal body weight is the weight corresponding to a body mass index (BMI) of 25 kg/m2 for the patient's height. Body weight is measured in kilograms (kg) on a clinic weighing scale and height in metres (m); both are recorded in the patient's follow-up file. Unit of measure: percentage (%) of excess body weight. |
| Secondary | Percentage of Patients With Improvement of Obesity-Related Comorbidities After Revisional Surgery | Up to 3 years after revisional surgery | Among patients with at least one obesity-related comorbidity before revision (such as hypertension, type 2 diabetes mellitus, dyslipidaemia or asthma), the percentage whose comorbidity improved after revision. Each comorbidity is assessed clinically by the treating surgical team at follow-up and recorded in the patient's follow-up file as "improved" or "not improved". Unit of measure: percentage (%) of patients. |
| Secondary | Percentage of Patients Reporting Improved Quality of Life After Revisional Surgery | Up to 3 years after revisional surgery | Patient-reported overall quality of life after revision compared with before revision. At follow-up, patients are asked whether their overall quality of life has improved after the revisional operation, and the answer is recorded in the patient's follow-up file as "improved" or "not improved". No validated quality-of-life questionnaire is used. Unit of measure: percentage (%) of patients. |
| Secondary | Number of Patients With Complications of Revisional Surgery | From the day of revisional surgery up to 3 years after surgery | Number of patients with any intraoperative or postoperative complication related to the revisional operation, as documented by the treating surgical team in the patient's medical and follow-up records. Unit of measure: number of patients. |
