Thirty-two patients required further abdominal operations 6-77 months after jejunoileal bypass for morbid obesity. Twenty operations were needed because of inadequate weight loss, while the remaining 12 patients had lost sufficient weight but had developed complications. In all 32 patients the lengths of functioning jejunum and ileum were measured and compared with those recorded during the original operation; elongation had occurred in 29. There was a striking difference between the median increase in jejunoileal length of 44 per cent when weight loss was inadequate and 7 per cent when weight loss was adequate (P less than 0.01). Similarly, intestinal circumference and mural thickness were greater in the first group. There appears to be a relationship between intestinal adaptation and the extent of weight loss after jejunoileal bypass.
32例患者在空肠回肠旁路术治疗病态肥胖6 - 77个月后需要再次进行腹部手术。20例手术是由于体重减轻不足，而其余12例患者体重减轻足够但出现了并发症。对所有32例患者测量了空肠和回肠的功能长度，并与初次手术时记录的长度进行比较；29例出现了肠管延长。体重减轻不足时空肠回肠长度的中位数增加44%，体重减轻足够时增加7%，两者之间存在显著差异（P<0.01）。同样，第一组的肠周径和肠壁厚度更大。空肠回肠旁路术后肠道适应性与体重减轻程度之间似乎存在关联。
