[Morphology of postburn cicatricial stenosis of the esophagus: examination of specimens obtained at spot biopsy].
The authors examined 352 biopsy specimens taken at fibroesophagoscopy in 71 patients with postburn cicatricial esophagostenoses varying in ages from 18 to 70 years. The time after the organ burn ranged from 1 1/2 months to 52 years. Formation of a young granulation tissue was found in treatment of ulcerated structures by bougieurage which is believed to be associated with mechanical effects of the manipulations. In epithelization of cicatricial structures of the esophagus, correlating interactions of the epithelium and connective tissues similar to those observed in healing of skin wounds were recorded. Epithelization of the structures was found to require the elimination of traumatizing effects by food masses. As a rule, languid chronic esophagitis and signs of parakeratosis and hyperkeratosis were found in the area of suprastenotic esophagectasias.
