The function of the 3-loop pelvic ileal reservoir as an alternative to total proctocolectomy and ileostomy is assessed experimentally in dogs and compared with normal rectum under identical conditions. No difference was found between the pelvic ileal reservoir and normal rectum in their ability to maintain continence. The efficiency of evacuation, however, is significantly better in normal rectum (P less than 0.01). Observations made over a prolonged period of time suggest that frequency of defecation, tenesmus and incomplete evacuation are persistent problems with an ileal reservoir. The results of the experiments concur with clinical findings that satisfactory continence may be achieved by using the ileal reservoir but that it does not possess the ability of normal rectum to evacuate completely. Hence the frequent need for self-catheterization.
在犬类动物中对三袢盆腔回肠贮袋作为全直肠结肠切除和回肠造口术替代方案的功能进行了实验评估，并在相同条件下与正常直肠进行了比较。盆腔回肠贮袋和正常直肠在维持控便能力方面未发现差异。然而，正常直肠的排空效率明显更高（P小于0.01）。长期观察表明，回肠贮袋存在排便频率、里急后重和排空不完全等持续性问题。实验结果与临床发现一致，即使用回肠贮袋可实现令人满意的控便，但它不具备正常直肠完全排空的能力。因此经常需要进行自我导尿。
