['To study the effect of rectopexy and sigmoid resection (resection rectopexy) on symptoms in patients with internal rectal intussusception.', 'Retrospective and prospective study.', 'University hospital, Norway.', '22 patients with internal rectal intussusception.', 'Resection rectopexy by an open (n = 13) or laparoscopically-assisted (n = 9) technique.', "Symptomatic outcome, patients' satisfaction, and morbidity. Outcome was based mainly on the validated KESS score, which covers 10 symptoms included in the definiton of constipation.", 'There was a significant reduction in all 10 symptoms. Two patients complained of incontinence which improved after operation. The number of patients with constipation was reduced from 20 to 8 (p = 0.000) and none became constipated. Mean (95% CI) colonic transit times before and after operation in 10 patients with constipation were 5.3 (4.1 to 6.4) and 4.0 (2.6 to 5.4) days (p = 0.083). Seven of these 10 patients had a reduction of both transit time and constipation score. Six patients had complications after open operations. These included one damaged ureter, reoperations for bleeding, incomplete intestinal obstruction, and 2 wound infections.'] Does resection rectopexy for internal rectal intussusception reduce constipation and incomplete evacuation of stool?
