[Clinical analysis of abnormal uterine bleeding treatment with Thermablate EAS].

OBJECTIVE

To study the two-year follow-up and contrast research for 182 patients by Thermablate EAS Uterine Balloon Therapy (UBT) or Transcervical Resection of Endometrium (TCRE).

METHODS

We followed up 90 cases of UBT and 92 cases of TCRE between Oct. 2003 and June 2005. The mean age of UBT group was 49.4+/-9.4 (34-81) years, and that of TCRE group 46.6 +/-8.4 (35-74) years. The mean following-up for UBT group was 17.3+/- 5.0 (6-27) months, and that of TCRE group 17.5+/-4.1 (6-27) months. There was no noticeable difference of the high risk for complication between the two groups. The follow up happens twice a year one month after the operation. The follow up started in Dec. 2005.

RESULTS

The chi(2) value of pain during operation between two groups is 12.744. The P value is 0.000. It has statistical significance. The pain of UBT group is heavier than TCRE. The chi(2) value of blood disappearance between two groups is 24.347. The P value is 0.000. It has statistical significance. The duration of the blood disappearance of UBT group is shorter than TCRE. The chi(2) value of discharge disappearance between two groups is 99.486. The P value is 0.000. It has statistical significance. The duration of the blood discharge of UBT group is shorter than TCRE. The chi(2) value of blood flow for two years after surgery between two groups is 4.708. The P value is 0.03. It has statistical significance. The blood flow of UBT group is much more decrease than TCRE. The chi(2) value of dysmenorrheal improved after surgery between two groups is 9.970. The P value is 0.002. It has statistical significance. The dysmenorrheal improved of UBT group is much better than TCRE.

CONCLUSION

Thermablate EAS UBT is a new generation of endometrial ablation. Two years clinical observation shows that pain can be controlled by oral medicine for UBT group. The blood and discharge disappearance of UBT group is shorter than TCRE. Two years after the surgery the improvement of blood flow and dysmenorrheal released is much better than TCRE. However it probably will take longer time to show its long term effectiveness.
