Removing part of the uterus using a keyhole surgery technique is a more effective way of treating heavy menstrual bleeding than the current most common operation, according to new research led by the University of Aberdeen.
The research, funded by the National Institute for Health Research was published in The Lancet last week: The Lancet
In the mid-1990s, Aberdeen researchers were among the first to show that endometrial ablation (destroying the lining of the womb) was an effective and less invasive alternative to traditional hysterectomy, which involves full removal of the uterus and the cervix.
Since then, hysterectomy has been considered a last resort for combatting heavy menstrual bleeding, which affects 25% of women in the UK.
However, in recent years, a number of trials comparing traditional hysterectomy and endometrial ablation showed that full removal of the uterus provided greater relief from symptoms but led to more complications.
Now, in this new study, Aberdeen researchers led by Professor Kevin Cooper, have shown that a modified hysterectomy technique where only the body of the uterus is removed (leaving the neck of the womb – the cervix – behind) using keyhole surgery, is as safe as endometrial ablation but much more effective.
Researchers carried out a randomised trial on 660 women with heavy menstrual bleeding, across the UK. Half had endometrial ablation while the other half had the new technique – laparoscopic supra-cervical hysterectomy (LASH). Fifteen months after their surgery, the women treated using LASH were more satisfied with their treatment, but complication rates were similar in both groups.
Professor Kevin Cooper from the University of Aberdeen, who is also a consultant gynaecologist with NHS Grampian, said:
“This study shows that LASH offers a more effective option than endometrial ablation, without any increased risks. Most women having this procedure get home within 24 hours and there are no restrictive rules for recovery, unlike traditional hysterectomy. Laparoscopic supracervical hysterectomy offers women another effective surgical choice for this common medical condition.”
Professor Siladitya Bhattacharya, of the University of Aberdeen, a co-author in this study, added:
“This study is the latest in a series of trials led by Aberdeen over the past 25 years, which have helped to make surgery for heavy menstrual bleeding safer and more effective.”
