    BackgroundRecent evidence suggests that National Health Service (NHS) rationing of bariatric surgery is biased toward super-obese patients without scientific basis. The aim of this study was to compare health, quality of life, and employment outcomes in morbidly obese (MO) versus super-obese (SO) patients after laparoscopic Roux-en-Y gastric bypass (LRYGB) to provide a basis for rationing.MethodsConsecutive patients undergoing LRYGB from January 2008-September 2009, with baseline body mass index (BMI)<45 kg/m(2) (MO) and BMI>60 kg/m(2) (SO) were identified from a prospective database. Seventy-six eligible patients were invited to complete a questionnaire comprising BAROS (bariatric analysis and reporting outcome system), EQ-5D (EuroQol-5D), EQVAS (Euro-QoL visual analog score), and employment status preoperatively and postoperatively. Anthropometric, demographic, and clinical data were recorded.ResultsFifty-one patients responded: 23 MO and 28 SO. Groups were matched for demographic characteristics and co-morbidities. The MO group had significantly higher percentage excess weight loss (%EWL) (82% versus 53%; t test: P<.001) and mean BAROS score (5.47 versus 4.21; t test: P = .025) than the SO group. EQ-5D improved significantly for both groups in 3 domains (self care, anxiety/depression, and pain/discomfort); there was no significant difference in improvement between groups. EQVAS was significantly higher for the MO group (90 versus 70; Mann-Whitney U: P = .001). Employment status changed for 8 patients postoperatively, but there was no significant difference between groups.ConclusionThese results suggest that MO patients appear to benefit more than SO patients from LRYGB and yet seem to be disadvantaged in some NHS Trusts in the United Kingdom for access to bariatric surgery. This study provides a baseline framework for further research to generate evidence for more scientific rationing of bariatric surgery.Copyright © 2013 American Society for Bariatric Surgery.
