目的: 探讨术前饮食行为对减重手术效果的影响,为预测减重手术效果提供参考。方法: 采用荷兰饮食行为问卷（Dutch Eating Behavior Questionnaire, DEBQ）及相关评分标准,对85例肥胖症行腹腔镜胃袖状切除的减重手术病人进行分组,分为限制性饮食组44例和非限制性饮食组41例,其中限制性饮食组再分为成功限制亚组27例与失败限制亚组17例。分别比较术前不同饮食行为组及亚组之间术后6、12个月的体重、体质量指数（body mass index, BMI）及多余体重减少率（excess weight loss, %EWL）改变。结果: 85例病人均成功接受减重手术。限制饮食组术后6、12个月体重和BMI显著高于非限制组,%EWL显著低于非限制组。限制饮食组中,成功限制亚组术后6、12个月体重和BMI显著高于失败限制亚组,%EWL显著低于失败限制亚组。结论: 术前饮食行为显著影响减重手术结果,可作为预测减重手术效果的参考。
Objective To investigate the impact of preoperative eating behavior on weight loss after bariatric surgery, and provide relevant reference for predicting effects of bariatric surgery. Methods Of 85 obese patients undergoing laparoscopic sleeve gastrectomy, 44 cases were in restricted diet group, which was further divided into successful restricted diet subgroup (n=27 cases) and failing restricted diet subgroup (n=17 cases), and 41 cases in non-restricted diet group based on the Dutch Eating Behavior Questionnaire. Body weight, body mass index (BMI) and percentage excess weight loss (%EWL) were compared between groups and between subgroups at 6 and 12 months postoperatively. Results All patients completed laparoscopic sleeve gastrectomy successfully. Body weight and BMI of cases in restricted diet group were significantly higher than those in non-restricted diet group, while %EWL was significantly lower at 6 and 12 months postoperatively. In restricted diet group, body weight and BMI of cases in successful subgroup were significantly higher than those in failing subgroup, while %EWL was significantly lower. Conclusions Preoperative eating behavior had much impact on results of bariatric surgery, which could be used as reference for prediction of the results of bariatric surgery.
