Objective To observed the clinical effect of longterm sacral nerve stimulation on anal rectal pain after lumbar surgery. Methods A total of 18 cases with functional anorectal pain(FARP) after lumbar surgery in our hospital from April 2015 to March 2018 were selected

of whom 3 cases refuse to accept the treatment

the other 15 cases received sacral nerve electrical stimulation.The Pittsburgh Sleep Quality Index(PSQI) and simplified MPQ pain questionnaire were used to evaluate the clinical effect in preoperative and postoperative 1 week

1 month

3 months

6 months

9 months and 1 year respectively. Results Fifteen cases of permanent sacral nerve stimulation before and after

The MPQ scale and PSQI of 15 patients with implantation of permanent sacral nerve stimulation in postoperative 1 week were better than those before implantation

the differences were significant(P＜0.05).In the MPQ scale

the PPI and PRI at 6 months after operation was better than those before implantation

the difference was statistically significant(P<0.01);PSQI and VAS score after 2 months were better than those before implantation

the difference were statistically significant(P<0.01)

meanwhile in 1year of follow-up

the PSQI and VAS score continued to decline

but the change was not obvious. Conclusion Long-term sacral nerve electrical stimulation in the treatment of lumbar anorectal pain has a good clinical effect

which can improve patients’ quality of life.
