Prevalence and severity of endometriosis at laparoscopic treatment of tubal ectopic pregnancy

Eligible patients will be invited to participate in the study by the Acute Gynaecology Unit consultant or Receiving Gynaecology registrar or resident. Interested participants are provided a copy of the Patient Information and Consent Form (PICF) to review and consent if they wish to proceed. Initial patient data about risk factors for ectopic pregnancy and symptoms of endometriosis is collected by the Acute Gynaecology Unit team member pre-operatively using the standardised hard-copy or electronic (Survey Monkey) questionnaire. Patients who choose not to participate will not be disadvantaged in any way with regard to their medical care. Consenting participants will undergo the laparoscopic treatment of ectopic pregnancy of their choice (salpingectomy or salpingotomy) as well as scoring for endometriosis using the revised American Fertility Society classification of endometriosis (r-AFS). Other laparoscopic findings will also be recorded e.g. adhesions including Fitz-Hugh-Curtis Syndrome. The intra-operative questionnaire will be completed by the lead surgeon immediately following the procedure, in the operating theatre or in the theatre recovery area. Questions to be completed are 1-23 of the Intra-operative Questionnaire, which includes the r-AFS. As per current practice, participants will not be consented to surgical treatment of endometriosis in the same procedure unless this is discussed pre-operatively with the patient and surgical team involved on a case-by-case basis and deemed appropriate. Both questionnaires (patient and intra-operative) are designed specifically for this particular study. Once informed consent has been obtained, each participant will be allocated a trial number. All the information collected (including data collected using Survey Monkey) will be de-identified and securely stored in a password-protected database, from which analysis will take place. Data entry will occur concurrently with recruitment and we expect data entry to be finalised 1-2 months after recruitment has completed. The database will be retained for 7 years after completion of the study then deleted. Duration of treatment for each participant will be 24-48 hours.
