Hi guys I originally had he op in 2008 at the UCLH in London, lost weight initially but after two years, it didn't matter what I did, I just kept gaining. I saw mr el hasani at Cheslfield park hospital in November 2015, he agree to give me a revision, during the op in January 2016 he saw that the tubes were the wrong lengths, and the malabsorption tubes were longer but 100%. Discharge notes state, reason for weight gain is due to lengths error. I will see surgeon again in 2 weeks so will ask more the.
