This study investigated possible determinants of food intake change after gastroplastry. Preoperatively and 6 and 12 months postoperatively, 27 morbidly obese patients were prospectively examined with 7-day food registration and radiologic measurement of pouch volume and stoma diameter. Pouch emptying was determined as the mean transit time by a scintigraphic method. None of the measured variables was found to influence the change in food intake taking place during the first 6 months, when most of the weight loss was observed. Between 6 and 12 months, the change of stoma diameter was positively associated with the change of solid foods consumed (by weight, p = 0.01; by energy content, p = 0.02). The change of pouch volume was negatively associated with the change of energy from beverages (p = 0.005). In conclusion, it seems impossible to tailor the reduction of food intake through adjustments of the surgical dimensions, at least within the ranges of our observations. Increased food consumption and decreased energy intake with beverages may be caused by late dilations, or vice versa.
本研究调查了胃成形术后食物摄入量变化的可能决定因素。术前以及术后6个月和12个月，对27例病态肥胖患者进行前瞻性研究，采用7天食物记录法以及通过放射学测量胃囊容积和吻合口直径。通过闪烁扫描法将胃囊排空确定为平均通过时间。在观察到大部分体重减轻的前6个月期间，未发现任何测量变量会影响食物摄入量的变化。在6至12个月之间，吻合口直径的变化与固体食物摄入量的变化呈正相关（按重量计，p = 0.01；按能量含量计，p = 0.02）。胃囊容积的变化与饮料能量摄入量的变化呈负相关（p = 0.005）。总之，至少在我们观察的范围内，似乎不可能通过调整手术尺寸来调整食物摄入量的减少。食物摄入量增加和饮料能量摄入量减少可能是由后期扩张引起的，反之亦然。
