CEES-U (Cambridge Endometriosis Endoscopic Surgery Unit)

Clinics A-Z

The CEES-U is accredited, with the British Society of Gynaecological Endoscopy, as an Endometriosis Centre. This means that we have a team who specialises in the treatment of severe endometriosis. We take a holistic and patient centred approach to care, considering all the factors endometriosis can have on a person’s life. The team at CEES-U have extensive experience in the management of endometriosis and benign gynaecological diseases, especially in laparoscopic surgery. We are dedicated to helping those suffering with endometriosis to understand their condition and have a better quality of life.

What is Endometriosis?

Endometriosis is a benign (non-cancerous) condition where tissue similar to the lining of the womb grows outside of the womb. This can be on the lining of the inside of the pelvis, on the ovaries, bowel or many other organs.

What causes Endometriosis and is it common?

The cause of endometriosis is not known. The average time to diagnosis in the UK is 7.5 years. 1 in 10 women of reproductive age in UK are estimated to be affected by endometriosis, and 10% worldwide, however we understand that not everyone who is diagnosed with endometriosis will identify as female.

What are the symptoms of endometriosis?

The most common symptoms include:

  • Painful or heavy periods
  • Pain in the lower abdomen, pelvis or lower back
  • Pain during sexual intercourse
  • Pain on opening your bowels
  • Infertility (difficulty getting pregnant)

How severe the symptoms are depends largely on where in your body the endometriosis is, rather than the amount of endometriosis you have. A small amount of endometriosis can be as painful as, or more painful than, a larger amount.

What are the treatment options?

Unfortunately there is currently no cure for the condition but we can help to manage the pain and other symptoms it may cause. Treatment options include:

Expectant management

As we know that endometriosis is a benign condition, if it is not causing you any problems and / or you are not looking to be pregnant then there is nothing we need to do about it.

Medical Management

This can be split into two main forms:

  • Hormonal treatment i.e. combined oral contraceptives / mirena coil etc
  • Pain relief i.e. pain medication, physiotherapy / exercises for pain, working with pain specialists in a ‘pain clinic’

Surgical Management

Each surgery is individual and will be discussed in detail with you, but usually involves a laparoscopy (keyhole surgery) and could include excision (removal) of any endometriosis or adhesions or removal of an endometrioma (ovarian cyst) if you have one. All of our surgical cases are discussed at our multidisciplinary team (MDT) meeting prior to the operation, this includes our experienced endometriosis surgeons, colorectal surgeons, urologists and pain management team so that everyone can give their specialist input.
