The five year follow up rates for the two groups were 97.5% and 98.1%, respectively. The multiple decrement life table analysis showed that there was a significant difference in the gross cumulative failure rates between the two groups. The 60th month gross cumulative failure rates for PAP group and PM group were 4.61% and 11.87%, respectively, thus indicating the efficacy of PAP to be significantly higher than that of PM. 97.7% users had cervical smear examinations, but no suspected cancer cells or cancer cells were found. Meanwhile, there was no known diseases related to the chemical reagent. This follow up study indicates that tubal sterilization by chemical instillation is a simple,safe and efficient female method. It suggested that this method would be introduced to a wider use on the basis of modification in the composition of chemical agents, standardized operational procedure, and improved administrative regulation in the use of this technology.展开更多

Methods: This study enrolled 776 women in rural area at three counties of Linxiang, Qiyang, Changsha of Hunan province in China between February 1990 and April 1992. Brief Neurosis Screening Scale (BNSS), Symptom Checklist 90 (SCL-90), sensitivity to pain, suggestibility were used to indicate subjects' psychological status. Logistic regression model and retrograde discriminant analysis were applied to develop a mathematical model. Results: Prevalence of psychosomatic reactions or symptoms was 54.8% before sterilization, 26.6% at three months and 16.4% at one year after operation respectively. Psychosomatic symptoms were verified to be the result of joint effects of multiple risk factors. The following risk factors were associated with postoperative symptoms: anger-hostility (RR=33.71), high suggestibility (RR=4.53), high neuroticism (RR=3.44), sensitivity to pain (RR=2.14) and operative sites (RR=2.05). A mathematical model to estimate the probability of developing psychosomatic symptoms in sterilization was established.Conclusions: More than half of women suffered from psychosomatic reactions before operation, and some of them did not recover after operation. The postoperative psychosomatic symptoms are the joint effect of multiple risk factors.展开更多
