Endometrial balloon ablation under local analgesia and intravenous sedation

We report a series of women (n = 16) with menorrhagia undergoing endometrial balloon ablation under local analgesia with light sedation. Ten women had significant, coexistent medical problems. The median duration of the procedure was 8.6 minutes (range 8.47-9.5 minutes). Postoperative assessment included pain scores assessed by linear analogue scale; requirement for opiate analgesia; length of postoperative stay and patient satisfaction with the procedure. The minimum postoperative follow-up was 6 months. The procedure was well-tolerated and in 80% of cases either no postoperative analgesia or simple analgesia only was required. Two women were admitted overnight, 1 for social reasons and the other for pain control. Three women ages 44, 54 and 55 years were amenorrhoeic at 6 months; 8 women were still menstruating but satisfied with the outcome and 5 women are seeking further treatment for menorrhagia. While the longer-term efficacy of the procedure remains to be established these results indicate that endometrial balloon ablation under local analgesia and light sedation, a simple and acceptable technique, may be a suitable alternative to more difficult procedures such as rollerball ablation. This is most likely to be the case in appropriately selected women who are willing to accept a reduction in menstrual flow rather than amenorrhoea as the treatment outcome. The main disadvantage of balloon ablation is the cost of the disposable balloons and the need for a dedicated electrosurgical unit.
