Outcomes of major bariatric surgical procedures

Bariatric surgery has been a defined surgical speciality for nearly fifty years. However, the number of weight loss procedures performed over the last 15 years has continued to increase exponentially. This is not surprising given the worldwide obesity pandemic. Whilst surgery is the only effective and durable therapy for obesity different procedures carry different risk/benefit profiles. An important sub-group of patients are those undergoing a second line bariatric procedure. Mostly, these are patients who have had an adjustable gastric band or gastroplasty and require Roux-en-Y gastric bypass, sleeve gastrectomy or bilio-pancreatic diversion. These second line surgeries are high risk, however, the precise risks and effects on quality of life and weight loss have not been determined in this setting. This project will evaluate a cohort of 300 patients who have undergone second line procedures. Data collected will include: preoperative details, operative approach, peri-operative complications (including mortality) and weight loss. All patients will be followed up using gastro-intestinal quality of life instruments.
