[The comparison of efficacy of female sterilization by modified Uchida technique and XXXX clips in China].

@entity1 @entity575
OBJECTIVE: To compare efficacy of female sterilization by modified Uchida technique and @entity575 clips and to evaluate the influence on operation procedure and clinical effect with or without surgery training of service providers. METHODS: A comparative, multicenter clinical trial was performed in 18 county and township-level service centers. Totally 2198 @entity1 underwent sterilization from these 18 study center were divided into 1116 @entity1 sterilized by modified Uchida technique and 1082 @entity1 by @entity575 clips. Those 18 centers were classified into 9 training groups which provide surgical skills of sterilization and other contents and 9 non training groups. Clinical documents of sterilization were recorded. All @entity1 were follow-up at 3, 6 and 12 months after surgery. RESULTS: There were no complications during surgery by both sterilization. The failure rate was 2.03% (22/1082) in @entity575 clip method and the mean operative time were (12.4    6.4) minutes in training group and (14.4    8.1) minutes in non training group. In modified Uchida method, the failure rate was 0.18% (2/1116) and the mean operative time were (16.2    4.9) minutes in training group and (19.0    8.6) minutes in non training group. The mean operative time between two groups reached statistical difference (all P < 0.05). Total ended rate in modified Uchida technique were 2.2/hundred @entity1 year in training group and 2.5/hundred @entity1 year in non training group, and the rate of @entity575 slips were 3.9/hundred @entity1 year and 4.8/hundred @entity1 year, which did not show significant difference (all P > 0.05). There was no significant difference in acceptability and side effects of all @entity1 between two methods (P > 0.05). The training of service providers could influence acceptability of @entity1 (P < 0.05). CONCLUSIONS: Clinical efficacy was not influenced by those two methods. The operative time and acceptability were improved by training surgeons in @entity575 clips method.
