简要总结
The goal of this clinical trial is to learn if the type of weight-loss surgery (sleeve gastrectomy or gastric bypass) affects binge eating, depression, and anxiety in adults with severe obesity. The main questions it aims to answer are:
Does sleeve gastrectomy lead to different changes in binge eating compared with gastric bypass?
Does the type of surgery lead to different changes in depression and anxiety symptoms?
Researchers will compare people who have sleeve gastrectomy with those who have gastric bypass to see if there are differences in binge eating, depression, and anxiety levels up to 12 months after surgery.
Participants will:
Complete questionnaires about eating habits, mood, anxiety, general health, and body image before surgery.
Undergo either a sleeve gastrectomy or a gastric bypass operation (both are standard care).
Follow a standard post-surgery diet plan.
Attend follow-up visits at 1 week, 2 weeks, 1 month, and then monthly for 12 months, where they will complete the same questionnaires again.
详细描述
This prospective cohort study compares two standard-of-care bariatric surgical procedures - laparoscopic sleeve gastrectomy (SG) and laparoscopic gastric bypass (Roux-en-Y or one-anastomosis) - with respect to postoperative changes in binge eating, depression, and anxiety. A total of 100 morbidly obese patients (50 per arm) aged 18-60 years with a body mass index ≥35 kg/m² (or ≥30 kg/m² with at least one obesity-related comorbidity) will be recruited from the General Surgery department at Kasr Alainy Teaching Hospital, Cairo University.
The choice of procedure is determined by a preoperative multidisciplinary evaluation considering baseline BMI, presence of gastroesophageal reflux disease, type 2 diabetes mellitus, and patient preference after detailed counseling. All operations are performed under general anesthesia; SG uses a 36-Fr bougie.
Validated Arabic versions of the following instruments are administered at baseline and at each postoperative visit (1 week, 2 weeks, 1 month, and monthly thereafter for 12 months):
Binge Eating Scale (BES) - primary outcome for binge eating
Beck Depression Inventory-II (BDI-II) - primary outcome for depression

研究组 & 干预措施
Laparoscopic Sleeve Gastrectomy (SG)
Participants undergo laparoscopic sleeve gastrectomy using a 36-French bougie. Standard perioperative and postoperative care according to bariatric surgery protocol. Follow-up at 1 week, 2 weeks, 1 month, then monthly for 12 months. Outcome assessments include Binge Eating Scale (BES), Beck Depression Inventory-II (BDI-II), Beck Anxiety Inventory (BAI), GHQ-28, BSQ-14, and EAT-26.
干预措施: Laparoscopic Sleeve Gastrectomy (Procedure)
Gastric Bypass (One Anastomosis or Roux-en-Y)
Participants undergo gastric bypass (either one anastomosis gastric bypass - OAGB, or Roux-en-Y gastric bypass - RYGB) based on preoperative multidisciplinary evaluation. Standard perioperative and postoperative care. Same follow-up schedule and outcome assessments as the SG arm.
干预措施: Gastric Bypass (Procedure)
结局指标
主要结局
Change in Composite Mental Health Score (Simple Sum)
时间窗: Baseline, 6 months, 12 months
Simple sum of raw scores from three scales: Binge Eating Scale (BES, 0-46) + Beck Depression Inventory-II (BDI-II, 0-63) + Beck Anxiety Inventory (BAI, 0-63). Minimum total = 0 (best mental health). Maximum total = 172 (worst mental health). Higher score = worse mental health. Primary endpoint is change from baseline to 12 months (lower score = improvement).
Binge Eating Scale (BES) Score Change
时间窗: Baseline, 6 months, 12 months
16-item self-report questionnaire. Each item scored 0-3. Total raw score range: minimum 0, maximum 46. Higher score = more severe binge eating. Clinical interpretation: 0-17 = no significant binge eating; 18-26 = moderate binge eating; 27-46 = severe binge eating.
Beck Depression Inventory-II (BDI-II) Score Change
时间窗: Baseline, 6 months, 12 months
21-item self-report inventory. Each item scored 0-3. Total raw score range: minimum 0, maximum 63. Higher score = more severe depression. Clinical interpretation: 0-13 = minimal depression; 14-19 = mild depression; 20-28 = moderate depression; 29-63 = severe depression.
Beck Anxiety Inventory (BAI) Score Change
时间窗: Baseline, 6 months, 12 months
21-item self-report questionnaire. Each item scored 0-3. Total raw score range: minimum 0, maximum 63. Higher score = more severe anxiety. Clinical interpretation: 0-7 = minimal anxiety; 8-15 = mild anxiety; 16-25 = moderate anxiety; 26-63 = severe anxiety.
次要结局
- Body Shape Questionnaire-14 (BSQ-14) Score Change(Baseline, 6 months, 12 months)
- General Health Questionnaire-28 (GHQ-28) - Likert Score(Baseline, 6 months, 12 months)
- Eating Attitude Test-26 (EAT-26) Score Change(Baseline, 6 months, 12 months)
- Percent Total Weight Loss (%TWL)(6 months, 12 months)
- Body Mass Index (BMI) Change(Baseline, 6 months, 12 months)
