Low rectal cancer is usually managed by ultra-low anterior resection (ULAR) with total mesorectal excision and straight coloanal anastomosis. However, following this procedure patients often suffer from frequency, urgency of bowel action and, occasionally, faecal incontinence. To overcome such problems, a colon pouch may be fashioned and a subsequent colon pouch-anal anastomosis performed. The physiological and functional outcome following the use of a colon pouch are appraised.
All relevant papers identified from a Medline search and papers from cross-referencing were reviewed.
Creation of a colon pouch following ULAR results in reduced bowel frequency, and a lower incidence of urgency and faecal incontinence. Although there is a slightly increased incidence of evacuatory disorder and need for enemas or suppositories, this appears to be a minor problem which may possibly be overcome by using a smaller colon pouch. Compared with straight coloanal anastomosis following ULAR, the creation of a colon pouch produced a superior functional outcome.
低位直肠癌通常采用超低位前切除术（ULAR），行全直肠系膜切除及直结肠肛管吻合术。然而，术后患者常出现排便次数增多、便急，偶尔还会出现大便失禁。为克服这些问题，可制作结肠袋并随后行结肠袋肛管吻合术。对使用结肠袋后的生理和功能结果进行评估。
对从医学文献数据库检索中识别出的所有相关论文以及交叉引用的论文进行综述。
ULAR术后制作结肠袋可减少排便次数，降低便急和大便失禁的发生率。尽管排空障碍以及需要灌肠或使用栓剂的发生率略有增加，但这似乎是一个小问题，使用较小的结肠袋可能会克服。与ULAR术后直结肠肛管吻合术相比，制作结肠袋产生了更好的功能结果。
