Local excision of XXXX not-exceeding the muscularis layer.

@entity5 @entity1 @entity189
AIM: The aim of the study was to compare the results of treatment by local excision of two different clinical stages of the @entity5 . MATERIAL AND METHODS: Fifty-eight @entity1 with early @entity189 were operated on during the last 26 years using different methods of local excision. The @entity189 were initially assessed as not-exceeding the muscularis layer of the rectal wall. The @entity5 , localized up to 12 cm from the anal margin, were removed by means of "parachute" excision (47 @entity1 ). In 6 @entity1 , @entity189 localized in the central part of rectum, was excised by means of the Localio method. Transanal endoscopic microsurgery was applied in 5 cases of @entity189 localized on the depth of 5-20 cm from the anal margin. RESULTS: After local excision the @entity1 were divided into two groups: I, @entity5 of @entity5 , not exceeding submucosal layer (26 @entity1 ); II, @entity5 of low or median degree of @entity5 with infiltration of muscularis layer (32 @entity1 ). There was a significant difference in @entity5 relapses between groups I and II. One @entity1 in group I and 9 in group II developed local recurrences (P < 0.05) and 5 @entity1 in group II had neoplastic dissemination (15.6%). CONCLUSIONS: Best results were obtained in @entity1 with @entity189 not exceeding submucosal membrane. In cases of rectal muscular layer infiltrations, the risk of @entity189 relapses was markedly higher. The use of transanal endoscopic microsurgery has permitted @entity5 from the upper rectum.
