Study Population, including Inclusion/Exclusion There are 507 patients that are eligible for inclusion to this study. The patients that will be included are only those patients that are eligible for a LAGB adjustment (thus excluding preoperative and the first post-operative visit) and have presented for review by the treating surgeon (single surgeon) in the year 2009. All non-gastric band and non-SAGB gastric bands have been excluded. Assessments by dietitians and psychologists have also been excluded.\n\n 4\\. Study Procedures Initial Patient consent for the VEW questionnaire is obtained in consultation with the treating surgeon and dietician where the expectation, benefits and knowledge are explained and confirmed. This occurs prior to the need for adjustments, that is, during the preoperative period. To date there have been no patients that have not participated with the questionnaire.\n\nThe VEW questionnaire is handed out to all eligible (please see description for eligibility in point three) upon arrival to the clinic. Patients are given five minutes to fill out the questionnaire which is then brought into the consultation with them.\n\nPatient care and treatment is done with the strictest adherence to the Declaration of Helsinki and in the aim of developing new and better guidelines for Best Practice for the treatment of patients who have had a LAGB.\n\n5\\. Duration of Study Twelve months starting 1st January 2009-31st December 2009.\n\n6\\. Procedure Type\n\nThe VEW score study is limited to patients that have had LAGB specifically the Swedish Adjustable Gastric Band (SAGB):\n\no SAGB -VC\n\n* SABG -QC\n* SAGB - 2100 The VEW questionnaire is used following all bariatric procedures but the study would be limited to the above subset of patients.\n\n 7\\. Primary / Secondary Safety and Efficacy Endpoints\n\nPrimary Efficacy Endpoints:\n\n* Optimal gastric band adjustment tailored for the patient for no pain on eating, no obstructions and urgent deflation of the band\n* Inappropriate adjustment of the LAGB\n* Identify and Decrease the incidence of maladaptive eating behaviours\n\nSecondary Efficacy Endpoints:\n\n* Excess Weight loss at 3, 6, 12 months\n* Eating behaviour at 3,6,12 months\n* Incidence of Vomiting\n* Fill frequency and outcome\n\n 8\\. Statistical Analysis Plan\n\nDue to the significant amount of data that is currently contained in the North Eastern Weightloss Surgery database I have decided to narrow the parameters to the following for this particular study:\n\no All patients will be broken into two arms, one control arm and one trial arm.\n\no The outcomes that will be looked for are:\n\n1. Number of adjustments per patient\n2. Efficacy of the adjustments\n3. Excess Weight Loss (EWL)\n4. Eating behaviour and its changes\n5. Food tolerances (as per the Moore-Bohn Food tolerance scale)\n\n9\\.
