Histological comparison between cryonecrosis and thermonecrosis has shown that cryonecrosis in generally better delimited and surrounded by a layer of finer and more regular granulation tissue than thermonecrosis. Moreover, the course of the cold lesion is faster and is less open to phenomena of suppurative septic and oedematous phenomena.
As matters new stand, cryosurgery has certain definite indications in various fields, either alone or in association with other forms of treatment. It is probably the therapy of choice for 1st-stage haemorrhoids and a series of skin lesions. It is of palliative value in the treatment of tumours and/or an addition to conventional management. The same is true of neoplasm in various sites and stages. As far as the immunological response is concerned, the data available are inconclusive. Further investigation is therefore justified, both experimentally and in man, bearing in mind all the parameters that can be used to assess a possible immune response.
An appraisal is made of the results of cryotherapy in 40 carefully selected cases of haemorrhoids. It is shown that the method is effective if practised in accordance with the correct technique and where specifically indicated. The incidence of possible complications and recurrences is also discussed. Points in favour of the method include its greater tolerability, the possibility of using it in out-patient management, and the fact that it permits an earlier return to work. Attention must be paid to the narrowness of its indications and the anorectal diseases that may often be present.
