We have developed an adjustable gastric band in which the stoma diameter can be adjusted from the outside. A standardized technique was employed and the application of our band in terms of weight loss and complication rate was evaluated
Between August 1990 and November 1991, 50 patients (15 men and 35 women) were operated on by laparotomy. Their mean age at surgery was 41 (19-60) years. Mean preoperative weight was 134 (106-181) kg and the mean BMI was 46 kg/m2 (range 33-59 kg/m2).
No patient was lost to follow-up. Four were excluded from the study (brain tumor, pregnancy and two reoperations). The remaining 46 were followed for at least 4 years. At follow-up, mean weight was 80 kg and mean BMI was 27.5 kg/m2. The patients had lost a mean of 54 kg. Two patients (4%) had abdominal reoperation because of technical problems. There was one incisional hernia and one minor wound infection, but no other significant complications.
This relatively simple method appears to be at least as good as the other operations, and weight loss can be adjusted to patient comfort. Currently, the procedure is being performed laparoscopically.
我们研发了一种可调节胃束带，其造口直径可从外部进行调节。采用了标准化技术，并对我们的束带在减肥效果和并发症发生率方面的应用进行了评估。
在1990年8月至1991年11月期间，50例患者（15名男性和35名女性）接受了剖腹手术。他们手术时的平均年龄为41（19 - 60）岁。术前平均体重为134（106 - 181）千克，平均体重指数为46千克/平方米（范围为33 - 59千克/平方米）。
无患者失访。4例被排除在研究之外（脑肿瘤、妊娠和2例再次手术）。其余46例至少随访了4年。随访时，平均体重为80千克，平均体重指数为27.5千克/平方米。患者平均减重54千克。2例患者（4%）因技术问题进行了腹部再次手术。有1例切口疝和1例轻微伤口感染，但无其他严重并发症。
这种相对简单的方法似乎至少与其他手术一样好，并且减肥效果可根据患者舒适度进行调整。目前，该手术正在通过腹腔镜进行。
