Patients following laparoscopic adjustable gastric banding (LAGB) are generally advised to avoid liquid calories, opt for solids and refrain from drinking with meals as this is believed to prolong satiety. The role of food consistency and satiety following LAGB is largely uninvestigated. The purpose of the study was to: (1) determine if food consistency impacts on post meal satiety in participants with well-adjusted LAGB and (2) compare the level of satiety achieved after consuming a solid versus a liquid meal between groups.
Twenty intervention (well-adjusted LAGB) and 20 control participants were recruited. All participants consumed three iso-caloric breakfasts that were randomised for nine mornings. Participants were asked to rate their satiety on visual analogue scales (VAS) at set times after the test meal. Areas under the curve (AUC) VAS scores were compared within and between groups.
Solids (bars) with or without water provided greater satiety than the liquids (shakes) for both groups. Drinking water with the bar did influence satiety in the intervention group. For the intervention group (LAGB), AUC VAS values for the bar with water were 77.4 ± 11.2* and 72.4 ± 16.7* for the controls.
Solid meals are more satisfying in both LAGB and non-LAGB individuals. However, a solid meal with accompanying water did not alter meal satiety.
接受腹腔镜可调节胃束带术（LAGB）治疗的患者通常被建议避免摄入液体卡路里，选择固体食物，并避免在用餐时饮用液体，因为这被认为可以延长饱腹感。LAGB 术后食物稠度和饱腹感的作用在很大程度上尚未得到研究。本研究的目的是：（1）确定食物稠度是否会影响 LAGB 调整良好的患者餐后饱腹感，（2）比较两组人群在食用固体和液体餐食后饱腹感的差异。
招募了 20 名干预组（LAGB 调整良好）和 20 名对照组参与者。所有参与者在九个早晨随机摄入三种等热量的早餐。参与者在用餐结束后设定的时间点使用视觉模拟量表（VAS）评估饱腹感。比较了组内和组间的 VAS 评分曲线下面积（AUC）。
固体（棒状）食物无论是否加水，其饱腹感均优于液体（奶昔），这对于两组人群均成立。在干预组中，在用棒状食物喝水会影响饱腹感。对于干预组（LAGB），带水的棒状食物的 AUC VAS 值为 77.4±11.2*，对照组为 72.4±16.7*。
固体餐在 LAGB 和非 LAGB 个体中均更令人满足。然而，固体餐伴随饮水不会改变餐食的饱腹感。
