In a population of patients undergoing bariatric revision surgery with conversion to RYGB and divided into two groups according to the surgical protocol: Group 1: robotic surgery Group 2: laparoscopy The primary objective of the study is to compare the rates of postoperative complications between the two groups, classified according to the Clavien Dindo classification. The secondary objectives are to compare between the groups: * Total duration of the surgical procedure, stay in the emergency room, and hospitalization * Postoperative pain * Adverse events * Weight loss * Improvement in comorbidities
The study procedures are the usual procedures of investigators who usually perform bariatric revision surgery. There is no change from the usual care. Participation in the study does not alter the benefit/risk ratio of the surgical procedure, does not alter the usual follow-up of patients who have undergone this type of surgery, and does not collect data other than those usually collected as part of follow-up.

NOT_YET_RECRUITINGPostoperative complication rate
The complications routinely screened for are: gastrointestinal fistulas (gastrojejunal anastomosis fistula, excluded gastric fistula, and loop foot fistula), bruit, anastomotic stenosis, anastomotic ulcer, splenic infarction, the development of a deep abdominal collection, and pulmonary and cardioembolic complications. The diagnosis of gastrointestinal fistula will be made in the event of signs of sepsis associated with the presence of an intra-abdominal collection on CT scan, the need for intravenous antibiotics with strict fasting and exclusive parenteral nutrition, and/or the need for surgical exploration. Depression is defined as the postoperative need for blood transfusion, with a drop in hemoglobin levels of at least 2.5 g/dL compared to the preoperative level. Postoperative complications will be obtained according to the Clavien Dindo classification
Time frame: 12 month
Post-operative PAIN
Post-operative pain will be assessed by a simple numerical scale rated from 0 (no pain) to 10 (worst pain ever experienced).
Time frame: Day 2
The total duration of the surgical procedure
Duration of anesthesia, duration of the surgical procedure,Length of stay in the Post-Anesthesia Care Unit, Time from end of surgery to first mobilization, Time from end of surgery to hospital discharge will be collected and compared between the two groups.
Time frame: Day 2
Weight loss
BMI will be collected during follow-up, and weight loss will be compared between the two groups.
Time frame: 12 month
Evolution of comorbidities
The occurrence, worsening, or resolution of the following comorbidities will be recorded: * Diabetes: type 1 or type 2 * Arterial hypertension * Dyslipidemia * Obstructive sleep apnea syndrome (OSAS) or other severe obesity-related respiratory disorders * Chronic osteoarticular conditions * NASH (non-alcoholic steatohepatitis) or other metabolic liver diseases * Metabolic syndrome (defined as the presence of at least three of the following metabolic abnormalities: increased waist circumference, hyperglycemia, hypertension, hypertriglyceridemia, low HDL cholesterol) * Nephropathy * PCOS (Polycystic Ovary Syndrome)
Time frame: 12 month
