The clinical outcome following ileoanal pouch operations vary greatly. To understand the underlying mechanism 15 S-shaped reservoirs and one J-shaped were studied by defecography (evacuation pouchography). Efficient evacuation was noticed when the reservoir was placed deep in the pelvis with the outlet of the pouch on a level with the 5th sacral vertebra or coccyx, and when the efferent limb was short (less than or equal to 7 cm) and straight. When the pouch was placed higher up in the pelvis and when the efferent limb was long and angulated, evacuation was impaired. Patients with efficient evacuation all had excellent clinical functions with few (less than or equal to bowel movements in 24 hours and no leakage, but when the evacuation was impaired there was a tendency towards more frequent stooling and leakage.
回肠肛管储袋手术后的临床结果差异很大。为了解其潜在机制，通过排粪造影（储袋排空造影）对15个S形储袋和1个J形储袋进行了研究。当储袋置于盆腔深处，储袋出口与第5骶椎或尾骨处于同一水平，且传出支短（小于或等于7厘米）且笔直时，可观察到有效排空。当储袋置于盆腔较高位置，且传出支长且有角度时，排空会受到损害。有效排空的患者均具有良好的临床功能，排便次数少（24小时内排便次数小于或等于 次且无渗漏），但当排空受损时，有排便更频繁和渗漏的倾向。 （注：原文中“less than or equal to bowel movements in 24 hours”表述不完整，这里按字面翻译后保留了原文的不完整性）
