Mr Arambage is a leading specialist in all stages of endometriosis (Stages 1–4), including the most complex cases involving bowel, bladder and other pelvic and abdominal organs. He works within a dedicated multidisciplinary team (MDT) at the BSGE-accredited Endometriosis Care and Research Centre at John Radcliffe Hospital — one of the UK's busiest centres for this condition.

Patients are regularly referred from across the UK and internationally. Mr Arambage offers a comprehensive approach from first consultation, including pelvic ultrasound and MRI review, through to surgical treatment and long-term management planning. He treats extra-pelvic endometriosis and is experienced in complex excision surgery.

His approach is always evidence-based and fertility-preserving where possible, drawing on co-authorship of the Cochrane review on surgical treatment of endometriosis.

Mr Arambage is an expert in advanced minimally invasive (keyhole) gynaecological surgery, having completed RCOG-accredited specialist training at John Radcliffe Hospital. He has trained senior registrars and consultants in these techniques across the Oxford deanery.

Laparoscopic surgery offers patients the benefits of smaller incisions, faster recovery, reduced pain and shorter hospital stay compared to open surgery. Mr Arambage performs a wide range of complex laparoscopic procedures to the highest standard.

Hysteroscopy uses a thin, lighted camera to examine the inside of the uterus. Mr Arambage co-authored the European guidelines on management of distension media in operative hysteroscopy, reflecting his expertise in this field.

Both diagnostic and operative hysteroscopy are available, enabling assessment and treatment of intrauterine pathology in a single visit where possible. This is particularly valuable for patients with abnormal uterine bleeding, suspected polyps or fibroids, and for fertility investigations.

Oxford Women's Clinic operates one-stop consultation and pelvic ultrasound clinics, meaning patients can receive a full clinical assessment and diagnostic imaging in a single appointment. This removes the need for multiple visits and delivers answers sooner.

The clinic is designed to assess and manage a wide range of gynaecological conditions efficiently, providing a personalised treatment plan on the day wherever possible. This model is especially valued by busy patients and those travelling from outside Oxford.

Mr Arambage provides virtual consultation clinics for patients across the UK and internationally. This enables patients who cannot travel to Oxford to access world-class specialist gynaecological care from their home.

Virtual consultations are ideal for second opinions, post-operative follow-ups, international referrals and patients with mobility or travel restrictions. Patients can share scan images and reports in advance for a thorough assessment.
