The value of age of onset and rectal emptying in predicting the outcome of colectomy for severe idiopathic constipation.

Abstract

We have evaluated the predictive value of pelvic floor dysfunction (as characterized by abnormal contraction during defaecation straining or absent balloon expulsion) and evacuation proctography on symptomatic severe idiopathic constipation after colectomy with ileorectal or colorectal anastomoses for improvement and the use of laxatives. We also determined whether there was a relationship between the age of onset of symptoms and the symptomatic outcome after surgery. Forty-four women (mean age 34 years) were studied. Twenty patients had had a preoperative evacuation proctogram. Of these, 8 evacuated completely and 12 incompletely. Of the 29 patients in whom puborectalis electromyography was..
