The relationship of distance from the surgical centre on attendance and weight loss after laparoscopic gastric bypass surgery in the United Kingdom.

Obesity remains a significant worldwide health problem and is currently increasing. Surgery remains the only proven long-term intervention and has been shown to be cost-effective. Evidence suggests that regular follow-up following laparoscopic adjustable gastric banding is related to improved outcome, such evidence is lacking for laparoscopic gastric bypass surgery (laparoscopic Roux-en-Y gastric bypass [LRYGB]). This study examines the effect of distance on attendance at post-operative clinics and subsequent weight loss following surgery. A prospectively maintained database was interrogated to analyze patients undergoing LRYGB before August 2010. Patient demographics, percentage excess weight loss (%EWL), compliance with out-patient clinic attendances and the distance the patients lived from the hospital were examined. Perfect clinic attendees were compared with non-attendees and the distances patients lived from the hospital evaluated. There was a significantly greater %EWL at 1 year post-op observed in the perfect attendees group (65.5 vs. 59.5, P = 0.01). Increased %EWL was also evident at 2 years post-op but did not reach statistical significance (66.9 vs. 59.5, P = 0.06). There was a negative correlation observed between post-operative weight loss and distance from the bariatric centre (R = -0.21, P = 0.04). Close follow-up following LRYGB is essential to optimize outcomes. Increased frequency of out-patient clinic visits was associated with improved post-operative weight loss. Increasing distance between the patient's home and the bariatric centre was associated with worse post-operative weight loss.
