  • Title: Changes in colorectal function in patients with chronic colonic pseudoobstruction.
    Author: Loening-Baucke VA, Anuras S, Mitros FA.
    Journal: Dig Dis Sci; 1987 Oct; 32(10):1104-12. PubMed ID: 3652897.
    Abstract:
    Motility studies of the lower bowel, radiology to exclude other gastrointestinal involvement, and rectal biopsies were carried out in 11 patients, age 21-60 years, with isolated chronic colonic pseudoobstruction. Repeated plain abdominal x-rays during symptomatic periods revealed massive gaseous colonic distension in all. Seven patients had the primary form while four patients had an underlying disease which could have been responsible for the chronic colonic pseudoobstruction. Lower bowel motility was decreased in patients with the primary form. Rectal wall elasticity was increased in both the primary and secondary form. Some of the abnormalities measured may suggest myogenic abnormalities of the sigmoid or rectal wall. No specific neural or muscular morphologic defect was identified in colonic transmural sections in eight patients except in the patient with Hirschsprung's disease. Five of seven patients with primary colonic pseudoobstruction achieved symptomatic relief only after subtotal colectomy and ileoproctostomy.
