The functional outcome after a low anterior resection for @entity5 is improved by a colonic J-pouch reconstruction. One functional problem with J-pouches is difficulty in evacuation, which is more common with large reconstructions. Since rectoceles are common findings on defecography in @entity1 with evacuation difficulties, we proposed that a @entity69044 may be thus found in @entity1 with large J-pouches. Pouchography was used to identify a @entity69044 ( @entity69044 ) in 26 @entity1 with a 10-cm J-pouch (10-J group) and 27 @entity1 with a 5-cm J-pouch (5-J group). Pouchography was performed at 3 months, 1 year, and 2 years after surgery. Functional assessments were performed 1 year postoperatively. Clinical function was evaluated using a questionnaire. The evacuation function was evaluated by the balloon expulsion and saline evacuation test. No @entity1 had an @entity69044 at 3 months or 1 year after surgery. An @entity69044 was significantly more common in the 10-J group than in the 5-J group at 2 years after surgery (P = 0.0374). An evacuation difficulty was significantly more common in the 10-J group than in the 5-J group. The evacuation function in the 10-J group was also significantly inferior to that in the 5-J group. An @entity69044 appearing 2 years after surgery is more common in @entity1 with evacuation difficulties and large colonic J-pouch reconstructions.

Detection of a XXXX in the colonic J-pouch using pouchography: cause or effect of evacuation difficulties?
