Between 1970 and 1975, 16 adolescent patients with a mean age of 17.8 years underwent jejunoileal bypass for exogenous morbid obesity. Their mean preoperative weight was 273.8 lbs. The total weight loss averaged 48 kg per patient. An extended evaluation process was instituted to determine the effectiveness of this procedure. Six of these parameters were the ponderal index (PI), body mass index, Broca's index, the per cent of ideal weight, complications, and diarrhea as a separate complication. A new formula was introduced to interpret weight loss as the percentage of excess pounds lost (PEPL). Three required reestablishment of normal intestinal continuity. There were no deaths in the group. Fifty and 69 per cent experienced excellent weight loss and postoperative PI respectively; excellent results were obtained in 27.5 per cent in both categories. In contrast, 50 per cent had a weight loss less than 100 lbs and 19 per cent a poor PI postoperatively; 13 per cent experienced poor results by both criteria. Linear growth in all patients continued along a normal curve, and their heights were above the mean.
1970年至1975年间，16名平均年龄为17.8岁的青少年患者因外源性病态肥胖接受了空肠回肠分流术。他们术前的平均体重为273.8磅。每位患者的总体重减轻平均为48千克。开展了一个全面的评估过程以确定该手术的效果。其中六个参数为肥胖指数（PI）、体重指数、布罗卡指数、理想体重百分比、并发症以及作为单独一种并发症的腹泻。引入了一个新公式，将体重减轻解释为超重磅数减轻的百分比（PEPL）。三人需要恢复正常的肠道连续性。该组无死亡病例。分别有50%和69%的患者体重减轻效果极佳以及术后肥胖指数良好；两类结果均极佳的患者占27.5%。相比之下，50%的患者体重减轻不足100磅，19%的患者术后肥胖指数较差；13%的患者两项标准的结果均较差。所有患者的线性生长均沿正常曲线持续，且他们的身高高于平均水平。
