title: [Towards a new classification of hemorrhoidal disease].
abstract: The generally accepted classification of hemorrhoids presents some rather wide gaps which may either be due to expressions of intrinsic limits or recent moves of the Colonproctology field. The authors of this paper would like to present their proposal for a new classification that considers the results of the National Multicentric Study that was performed in collaboration with nineteen centres and a total of 1,494 patients. In addition, a comparative study was conducted on the two forms of classification. Nineteen patients (1.28%) were considered unclassifiable with the new classification system while 49 were (3.29%) with the presently used one. These results were found significant with the MacNemar Chi-Square test. The description of type 2 and 3 in the new classification system was found useful in 69% of 2nd degree, 77% of 3rd degree and 28% of 4th degree using the present system. Acute events (type 5,6 and 7) proposed with the new classification were found in the present system with several different rates. We have also included the data taken from a national and international survey we conducted on the usefulness of the new classification that provoked intense debate within two of the most important national institutes. The result was the elaboration of a design on the new classification.
