[The mucosal status of the large intestine in the irritable bowel syndrome and in chronic noninfectious nonspecific colitis].

Morphometry was carried out of the surface epithelium, of crypts as a whole and their epithelium in rectal mucosa (RM) biopsy specimens from patients with irritable colon syndrome (ICS) and chronic non-infectious unspecified colitis (ChNUC). Of the RM morphometric parameters, it is the intestinal crypt external diameter (CED) that exhibited most extensive correlations, which fact enabled the authors to use CED for systematization of ICS and ChNUC patients. Interrelationship was established between CED, ICS clinical picture and ChNUC rates.
