Body composition was measured in 24 patients who had previously undergone proctocolectomy and ileostomy. One group (control group) had undergone resection of only small amounts of terminal ileum (median 4 cm), the other group of patients (resected group) had undergone resection of greater lengths of small bowel (median 54 cm). These values of body composition were then compared with predicted values in normal subjects. Proctocolectomy and ileostomy without ileal resection did not significantly affect body weight, or the body contents of fat or water, but led to a reduction in total body nitrogen and total body potassium, suggesting a reduction in fat free mass. A modest resection of the terminal ileum undertaken during the course of proctocolectomy decreased body weight largely because of a reduction in body fat. None of the ileostomy patients was found to be dehydrated.
对24例曾接受直肠结肠切除术和回肠造口术的患者进行了身体成分测量。一组（对照组）仅切除了少量回肠末端（中位数为4厘米），另一组患者（切除组）切除了更长长度的小肠（中位数为54厘米）。然后将这些身体成分值与正常受试者的预测值进行比较。未进行回肠切除的直肠结肠切除术和回肠造口术对体重、脂肪或水分的身体含量没有显著影响，但导致全身氮和全身钾减少，提示去脂体重减少。在直肠结肠切除术中对回肠末端进行适度切除主要因身体脂肪减少而导致体重下降。未发现回肠造口术患者有脱水情况。
