Where patients express an interest in the A.M.I. Protector Band, they will be given a Patient Information Sheet which will form the basis of a discussion with the attending physician. Patients opting for the Protector Band will be told that their anonymised clinical data will be stored in a secure database and used for research purposes. They will also be required to attend for regular follow-up (see below) for a period of three years after implantation.
Following this initial consultation, a minimum period of 2-weeks will be required before the patient is listed for surgery. This will provide a suitable period during which the patient can consider the options and seek clarification on any points about which they are unclear.
In the case of the A.M.I. Protector Band the surgery will be performed in two locations:
- Spire Hospital Parkway (Birmingham)
- Spire Hospital Manchester
All band procedures will be performed by one of two surgeons; Mr. Paul Super and Prof. Franco Favretti according to a standard protocol.
In all cases, informed consent will be obtained prior to surgery.
Patients will remain in hospital overnight and be discharged the following day.
On discharge, patients will be given comprehensive written instructions regarding optimal nutritional and physical activity. They will also be provided with a 24-hour, Emergency Helpline number in the event of problems.
All patients will be followed for a period of three years, with a formal review at 5 weeks and then at 3, 6, 9, 12, 18, 24 and 36 months. However, patients will be free to attend additional clinics between the formal reviews should they wish. At each visit the patient's weight, height, waist/hip ratio and blood pressure (BP) will be recorded. In addition, a range of blood tests will be carried out at baseline, at 12, 24 and 36 months. A self-administered Quality of Life questionnaire will be completed prior to surgery and then at 12, 24 and 36 months of follow-up.
At the completion of the 3-year study, patients will be able to transition into our usual care gastric band programme for long-term follow-up.
