The significance of internal rectal intussusception (rectal invagination) in chronic constipation dominated by symptoms of obstructed defecation is not fully clarified.
Seventeen consecutive patients with chronic constipation and a history of obstructed defecation with internal rectal intussusception demonstrated by defecography were treated by perineal rectopexy.
Of 15 patients followed up for more than 2 years defecography showed total disappearance of the intussusception in 12. Five of these claimed substantial improvement (42%; 17-72%). Three of four patients with concomitant anal incontinence became fully or partly continent after the rectopexy.
In some patients with chronic constipation, dominated by symptoms of obstructed defecation, rectal invagination may be an aggravating factor. The study indicates that rectal invagination does not seem to be the cause but rather a consequence of the obstructed defecation. In selected patients, including those with concomitant faecal incontinence, surgical treatment of the intussusception by a minor procedure may be indicated.
以排便梗阻症状为主的慢性便秘中，直肠内套叠（直肠套入）的意义尚未完全阐明。
对17例连续的慢性便秘患者进行治疗，这些患者有排便梗阻病史，排粪造影显示存在直肠内套叠，采用会阴直肠固定术进行治疗。
在15例随访超过2年的患者中，排粪造影显示12例套叠完全消失。其中5例称有显著改善（42%；17 - 72%）。4例伴有肛门失禁的患者中，有3例在直肠固定术后完全或部分恢复控便能力。
在一些以排便梗阻症状为主的慢性便秘患者中，直肠套入可能是一个加重因素。该研究表明，直肠套入似乎不是排便梗阻的原因，而是其结果。对于选定的患者，包括伴有大便失禁的患者，可能需要通过一个小手术对套叠进行外科治疗。
