2. Disclosure
Nothing to disclose.

3. Introduction
Obesity is frequently associated with non-alcoholic fatty liver disease.
The spectrum ranges from simple steatosis, non-alcoholic steatohepatitis to cirrhosis.
Bariatric surgery is the most effective treatment against obesity. Nevertheless, cirrhotic patients may have higher peri-operative risks and the long-term evolution of liver disease is unknown.

4. Aim
To report our experience in 12 cirrhotic patients who underwent bariatric surgery.

5. Methods
Retrospective analysis of our Bariatric electronic database from January 2006 to January 2014.
Description of:
Cirrhosis diagnosis in relation to bariatric surgery.
Liver enzymes profile progression after surgery (1-2 years).
Surgical complications and surgery-associated mortality.

11. Results No peri-operative complications.
No liver dysfunction after surgery.
No upper GI bleeding in the long-term follow-up.
One of the known cirrhotic patient developed a hepatocarcinoma – delayed OLT for 6 years.
One patient died 6 years after surgery because of trauma.

12. Conclusions
Bariatric surgery is feasible and safe in Child A cirrhotic patients with low morbidity and no mortality.
Long-term evolution of liver disease after bariatric surgery is unknown, although we have not seen liver disease progression in our patients.
