The functional outcome after low anterior resection for rectal cancer using colonic J-pouch reconstruction(J) is superior to that using conventional straight reconstruction(S). 1.One disadvantage of J is evacuation difficulty, which has been associated with large pouches. The purpose of this study was to elucidate the causes of evacuation difficulty in large pouches using pouchography. The evacuation difficulty observed in patients with large J is associated with excessive distention and horizontal inclination of the pouch occurring within one year of surgery. In patients with evacuation difficulties and large J, straining caused by evacuation difficulty results in a rectocele-like prolapse appearing two years after surgery. 2.Few reports on the long-term functional outcome of J have been published, and data comparing J and S are contradictory. This prospective study compares the functional outcome of J and S three and five years after low anterior resection for rectal cancer. J increased reservoir function and provided better a functional outcome than S, even three and five years after surgery, especially in patients whose anastomosis is less than 4 cm from the anal verge. 3.No report is available on comparison of the long-term changes in the functional assessments of J and S over time. From one to five years after surgery, functional outcome was improved both in J and in S, and this improvement was greater in S than in J.

直肠癌低位前切除术后，采用结肠J形袋重建（J）的功能结果优于采用传统直型重建（S）的功能结果（上级）。1. J的一个缺点是排空困难，这与大袋有关。本研究的目的是阐明原因的排空困难，在大袋使用袋造影。在大J患者中观察到的排空困难与手术后一年内发生的囊袋过度扩张和水平倾斜有关。对于有排空困难和大J的患者，排空困难引起的紧张导致术后2年出现直肠脱垂样脱垂。2.关于J的长期功能结局的报道很少，比较J和S的数据相互矛盾。这项前瞻性研究比较了直肠癌低位前切除术后3年和5年J和S的功能结局。J增加了储库功能，提供了比S更好的功能结局，即使在术后3年和5年，特别是在吻合口距离肛门边缘小于4 cm的患者中。3.没有关于J和S功能评估随时间的长期变化的比较报告。术后1 ~ 5年，J组和S组的功能结局均得到改善，且S组的改善程度大于J组。
