Trial Review

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Titles & IDs
Public title
Laparoscopic investigation of endometriosis using confocal endomicroscopy.
Scientific title
Women with symptoms of endometriosis who are indicated for diagnostic or therapeutic surgery undergo in vivo microscopic imaging of endometriosis lesions for comparison with conventional histopathological analysis of biopsied lesions to assess the diagnostic potential of endomicroscopy in identifying lesions prior to therapeutic intervention.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Confocal endomicroscopy
In vivo microscopic imaging using an intravenously administered fluorescent contrast agent (Fluorescein Sodium 10%), is performed during the participant's therapeutic or diagnostic surgery. Depending upon the number of lesions identified, endomicroscopic imaging is expected to add 10-20 minutes to each participant's laparoscopic surgery (1 session per participant).
Intervention code [1] 2121 0
Diagnosis / Prognosis
Comparator / control treatment
Suspected endometriosis lesions will be biopsied at the time of laparoscopy, immediately prior to surgical intervention (e.g. ablation, excision) for conventional histopathological confirmation of the tissue type (endometriosis - uterine epithelium, endosalpingiosis - Fallopian tube epithelium, fibrosis, other normal tissue).
Control group
Active

Outcomes
Primary outcome [1] 3396 0
Endomicroscopy images from each lesion.
Timepoint [1] 3396 0
During laparoscopy approximately 20-30 images per lesion will be collected to document the surface and subsurface cellular structure.
Primary outcome [2] 3397 0
Macroscopic appearance of each lesion.
Timepoint [2] 3397 0
At laparoscopy, the macroscopic appearance of each lesion will be recorded and assessed immediately prior to collecting endomicroscopy images.
Primary outcome [3] 3398 0
Conventional histology from each lesion.
Timepoint [3] 3398 0
Histopathological analysis of each biopsied lesion will be available from pathology approximately 1 week post laparoscopy.
Secondary outcome [1] 5631 0
Accuracy of endomicroscopy for predicting histology based on a simple image classification system.
Timepoint [1] 5631 0
Predictions of histology will be made during laparoscopy immediately after images of each lesion are obtained and before the conventional histology results are known (accuracy of predictions will be measured in the second series of patients only, once data from the first 8 patients are analysed).
