Specialist expertise
Hysteroscopy, by the surgeon who teaches it.
Mr Subramanian is the clinical lead for hysteroscopy at King's College Hospital and King's Fertility and the RCOG South London Preceptor for Hysteroscopy, the regional lead who trains gynaecologists across London in it. He performs over 200 hysteroscopies a year. Many are carried out in the outpatient clinic without a general anaesthetic.
What it is
A look inside the womb, and treatment at the same time.
Hysteroscopy uses a slim telescope, passed through the cervix, to examine the lining of the womb directly. Many conditions found this way can be treated during the same visit.
Uterine polyps
Diagnosed and removed, often in the same outpatient visit.
Submucosal fibroids
Hysteroscopic resection of fibroids that distort the cavity.
Uterine adhesions
Division of scar tissue inside the womb to restore the cavity.
Heavy or abnormal bleeding
Direct inspection of the lining with endometrial biopsy where needed.
Before fertility treatment
Assessment of the cavity as part of a fertility work-up, alongside HyCoSy and saline sonography.
Retained tissue after pregnancy
Hysteroscopic management as an alternative to blind surgical evacuation.
Credentials in hysteroscopy
Trained in it, then trusted to teach it.
His research includes the British Fertility Society's national guideline on the management of endometrial polyps in fertility, published in Human Fertility.

What to expect
From consultation to going home the same day.
- 01Consultation and scan
A full history and an ultrasound performed by Mr Subramanian in the room, so the reason for the hysteroscopy is clear before it is offered.
- 02The procedure
A slim telescope is passed through the cervix to view the inside of the womb on a screen. In most cases this is done in the outpatient clinic without a general anaesthetic, with local anaesthetic and inhaled pain relief (Penthrox) available so you can choose what suits you.
- 03See and treat
Where appropriate, polyps and small fibroids are removed during the same visit rather than at a second appointment.
- 04Afterwards
Most patients go home the same day. Findings are explained at the time, and a written plan follows.
Surgical gallery
Hysteroscopic findings, as seen on the screen.
Images taken during hysteroscopy. They are clinical photographs and some people prefer not to see them, so they stay hidden until you choose to look.
And surgery
Minimally invasive surgery, when it is needed.
Where a condition cannot be treated through the cervix, laparoscopic (minimally invasive) surgery offers smaller scars, less pain and a quicker return to normal life than open surgery.
Gynaecological surgeryLaparoscopic surgery
Key-hole surgery for ovarian cysts, endometriosis and pelvic pain.
Myomectomy
Fibroid removal that preserves the womb and future fertility.
Oophorectomy and salpingectomy
Removal of ovaries or fallopian tubes where clinically needed.
Adhesion surgery
Division of pelvic and uterine adhesions to restore anatomy.
