Evaluation of the PPP/endometriosis patient Women with endometriosis and/or pelvic pain are referred to our centre by their family physician or specialist. We are a tertiary centre of care, with four gynaecologists evaluating approximately 1000 patients per year coming from the entire province of British Columbia (population of 4.7 million, spread out over 947,000 km 2) (10).
