Surgical Evacuation with intraopErative Ultrasound: a pilot trial to assess feasibility          


Important Message: COVID-19

We are now home-based during the COVID-19 pandemic but available and working. Responses may however take longer than normal as staff may be working altered hours but we are cross covering trials as required and urgent matters will be dealt with promptly. Please do not contact our usual office/landline number and instead email the trial contact and copy in the trial mailbox. If a query requires a prompt response please mark as ‘urgent’ in the email subject header.


Aim: To test the premise that intraoperative ultrasound can reduce the incidence of early and late complications following surgical removal of products of conception. 

Process outcomes:

To obtain estimates for important aspects of the protocol to allow development of a substantive trial, specifically:

 1.         To derive real-time data on the design aspects of the study:

 I.          Proportion of eligible women of those screened.

 II.         Proportion of eligible women randomised.

 III.        Attrition rates (proportion of women followed-up at 2 to 4 and 4 to 8 weeks)

 IV.        Proportion of women switching treatments.

2.         To derive a realistic understanding of trial processes, in particular:

 I.          Ascertain robustness of the data collection process during and after the surgical procedure.

 II.         Determine the support required in units to ensure successful recruitment.

 III.        Determine why patients decline participation or withdraw after randomisation.

Primary clinical outcome measure: A composite outcome of unsuccessful procedure or any of the following complications: intrauterine adhesions, infection, severe bleeding or damage to the genital tract.

Secondary clinical outcome measures: Rate of individual complications; rate of serious adverse events; need for additional surgical procedure(s) for miscarriage treatment; need for medical management of miscarriage.
