Safety aspects of hysteroscopy, specifically in relation to entry and specimen retrieval: a UK survey of practice

The purpose of this study is to evaluate current practice amongst gynaecologists across the UK, regarding safety aspects of inpatient hysteroscopy under anaesthesia, specifically in relation to entry and specimen retrieval.

A survey was created using survey monkey. The first round was circulated to all registrar trainees and consultant gynaecologists across Wales. Following a good response, the survey was then circulated to all members of the British Society of Gynaecological Endoscopy (BSGE).

There were 212 responses including, 140 consultants, 36 senior registrars, 17 junior registrars and 18 clinical nurse specialists. In total, 136 out of 212 (64.7%) always perform a vaginal examination prior to hysteroscopy. 10.4% always sound the uterus, and 5.2% always dilate the uterus prior to insertion of the hysteroscope. Twenty-three consultants, six senior registrars, three junior registrars and one clinical nurse specialist knew how to position the internal cervical os as visualised through the scope when using a 30° hysteroscope. 35.8% of candidates always perform a post-procedure cavity check, and 9% use suction to flush the cavity to aid vision during the post-procedure cavity check. The majority (76%) predicted dilatation as the stage most likely to cause uterine perforation and predicted the most likely site for perforation as the posterior uterine wall in the anteverted uterus and the anterior uterine wall in the retroverted uterus.

This study highlights varied practice across the UK regarding safety aspects of hysteroscopy, in relation to entry and specimen retrieval. There is a need for increased awareness of the risks of hysteroscopy and paramount precautions that should be performed routinely as part of their practice. Standardised guidelines may be a beneficial tool to help bring about this change in practice, leading to a reduction in uterine perforation rates.
