Risk factors for constipation The most important risk factor for constipation after rectal fixation for rectal prolapse is young age. They have a higher rate of recurrence and in most of these individuals, constipation takes up a large part of their lives. In most of these young people, rectal prolapse is secondary to a long history of chronic straining to defecate. Therefore, young people with rectal prolapse will be studied in a complete survey. In this group, not only will there be an assessment of colonic transmission, but also of small bowel transmission and even gastric emptying as in patients with total upper gastrointestinal disease or neuropathy. However, it is difficult to identify patients with anal pain using electromyography to assess the activity of the puborectalis muscle during forceful defecation. Total gastrointestinal weakness prohibits any resection and pelvic drainage obstruction may be the result of biofeedback or botulinum toxin injections. Other risk factors for postoperative constipation are: 1) patients with extensive perineal prolapse; 2) patients with a history of straining to defecate; and 3) patients with concomitant isolated rectal ulcers.
