title: [Analysis of 618 cases of radical resection of rectal carcinoma].
abstract: OBJECTIVE
  To investigate and analyse curative effects of Miles operation and anal sphincter preserving operation for rectal carcinoma in 20 years.
  
  
  METHODS
  From 1984 to 2004, 618 cases of rectal carcinoma that underwent radical resection including Miles operation and anal sphincter preserving procedures were analysed retrospectively each 10 years, earlier 10 years from 1984 to 1994, and later 10 years from 1994 to 2004.
  
  
  RESULTS
  Among the 618 cases, 492 (79.6%) were followed up. The median of the follow-up time was 5.4 years. In the earlier 10 years, local recurrence rate of post operation was 6.9% (14/201), for Miles operation and anal sphincter preserving procedures the local recurrence rate was 6.7% and 7.1% respectively. In the later 10 years, the local recurrence rate was 5.1% (15/291), 4.8% for Miles operation, 5.2% for anal sphincter preserving procedures. With the procedure of canular anastomosis of colon and rectal mucosa, the local recurrence rate was 4.9%. Overall five-year survival rate was 64.7% (130/201) in the earlier 10 years, 66.3% (59/89) for Miles operation, 63.4% (71/112) for anal sphincter preserving procedures. In the later 10 years, the five-year survival rate was 68.0% (198/291) in all, for Miles operation 66.3% (55/83), for anal sphincter preserving procedures 68.7% (143/208). With the procedure of canular anastomosis of colon and rectal mucosa, the five-year survival rate was 71.3% (62/87).
  
  
  CONCLUSIONS
  The operation for rectal cancer should be chosen individually according to locus, biological character, and clinical stages. Anal sphincter preserving procedures are performed increasingly, and they provide the same five-year survival rate as Miles operation does, and the patient's quality of life can be improved obviously.
