Outlet syndrome: is there a surgical option?

Of 46 patients investigated for constipation, 21 were found to have some other primary abnormality, leaving 25 patients for study: 6 had evidence of the outlet syndrome alone, 5 had slow transit constipation, 8 had both abnormalities and 6 had no apparent physiological disorder in the colon or rectum. Although colectomy and ileorectal anastomosis gave good results for slow transit constipation, partial pelvic floor division provided satisfactory long-term improvement in only one of the 7 patients with the outlet syndrome.
