Bariatric and Metabolic Surgery

New operating theatre

We now provide Bariatric and Metabolic Surgery Service at University Hospital Lewisham.

We have a full multidisciplinary team and can offer a one stop assessment with a consultant bariatric surgeon (Ms Cynthia Borg, Mr Midhat Siddiqui), a specialist nurse, a dietician and a consultant anaesthetist. We will be offering the full range of bariatric procedures including laparoscopic gastric bypass, sleeve gastrectomy and gastric banding. We also have a comprehensive post-operative follow-up pathway.

We will be accepting referrals for patients who fulfil the NICE1 and current commissioning guidelines2. These are:

  • Patients aged 18 or over1,
  • BMI ≥ 40 kg/m2 or BMI ≥ 35 kg/m2  with other significant disease including type 2 diabetes mellitus, sleep apnoea, hypertension and benign intracranial hypertension1
  • The patient has had a BMI of 30 or more for 5 years or more2,
  • The patient has complied with a specialist Tier 3/4 non-surgical weight loss programme for a period of 12 months or more (BMI: 35-49) 2.  If BMI ≥ 50, the minimum acceptable period for weight loss programme is six months2.
  • The patient commits to need for long term follow up and has no history of drug/alcohol abuse or dependence1

We suggest that patients have their fasting lipids and fasting glucose, FBC, U&E, creatinine, B12, folate, calcium and Vit D checked prior to referral and that these tests are included in the referral letter.
