I had my band done by Mr Hewin without any problems. The only problems I have had are that I have needed 2 emergency de-fills. The first time I managed to get from Portsmouth to THG Hammersmith Clinic on a Saturday morning and the second time was a Sunday evening so I had to go to a nearby hospital where I knew there was a big bariatric department. Neither time was the fault of THG, just one of those things. The dieticians have been very supportive and the nurse who does the band fills in Southampton, and travels from Birmingham I believe, has been lovely and oh so apologetic on the 2 occasions she has overfilled me I have no complaints about THG.
You can read more about Mr Hewin online as he works for Gloucester NHS as a bariatric surgeon.
Hope all goes well for you.
