Superficial - Quickly (1 - 2 ), Deep

Superficial - quickly (1 - 2 ), deep heal with formation of granulations and a connecting fabric. Healing occurs slowly, a connecting fabric and - hem formation probably during 2 - 6 months Are the period chronic - . Cicatricial narrowings of a gullet - are formed more often in several places, in process is quite often involved surrounding . Unions and - gullet deformation develop-. Rubtsovo-ulcer process in a gullet after chemical burns can last for years. As a result of it at separate patients cicatricial narrowings of a gullet arise even after the lapse of 10 - 20 years from the moment of a burn. Thus, at a burn it is possible to distinguish four stages of pathoanatomical changes conditionally: I stage - and a mucous membrane hypostasis, II stage - and , III stage - formation of granulations, IV stage - scarring. At chemical burns of a gullet the substance accepted inside renders, besides local, and action on an - organism from which first of all suffer heart, a liver, kidneys. Heavy nephritic insufficiency can develop.
