Obstructed defecation may be caused by a rectocele and/or enterocele. Rectal wall procidentia may be due to an enterocele bulging into the rectum. Another cause of rectal procidentia resulting in obstructed defecation is presented. A 65-year-old woman complained of vaginal prolapse and incomplete bowel emptying. Pelvic examination revealed that a stage III anterior vaginal wall prolapse caused a mobile posterior vaginal wall to prolapse into the anal canal, resulting in rectal procidentia and subsequently in obstructed defecation. Careful assessment of all pelvic floor compartments is important to identify the cause of obstructed defecation, particularly in the absence of a rectocele.
排便梗阻可能由直肠膨出和/或肠膨出引起。直肠壁脱垂可能是由于肠膨出突入直肠所致。本文介绍了导致排便梗阻的直肠脱垂的另一个原因。一名65岁女性主诉阴道脱垂和排便不尽。盆腔检查发现，Ⅲ度阴道前壁脱垂导致活动的阴道后壁脱垂至肛管，引起直肠脱垂，继而导致排便梗阻。仔细评估所有盆底结构对于确定排便梗阻的原因很重要，尤其是在没有直肠膨出的情况下。
