Each area will first be viewed and photographed under white light. The absence or presence of suspected endometrial lesions will be noted. If suspected lesions are seen, the number of lesions, the extent of the lesions and the surgeon's confidence in the lesion being endometriosis will be recorded. Photographs will be labeled by quadrant and all lesions will be circled and numbered. Clinicians will record their degree of confidence on a 5 point likert scale that the lesion to be excised is a lesion of endometriosis.
