Recurrent rectal prolapse or postoperative rectal stricture occurred in four of 88 patients (4.5 per cent) who underwent Teflon sling repair at the Lahey Clinic during the past 15 years. Management of these and six other similar patients referred for treatment suggests that young men appear to be at a higher risk for recurrence. Strictures may be more likely to develop in patients with a long history of prolapse or problems with constipation. Teflon sling repair followed by recurrent prolapse or stricture formation should probably be treated by low anterior resection.
