Effect of mood and eating disorders on the short-term outcome of laparoscopic Roux-en-Y gastric bypass.
BACKGROUND
We examined whether patients with a history of mood and eating disorders (MED) had less weight loss and poorer treatment compliance after laparoscopic Roux-en-Y gastric bypass (LRYGBP) than patients with a history of either mood (MD) or eating disorders (ED), or no history of mood or eating disorders (ND).


METHODS
Consecutive LRYGBP patients (n = 196; 43.6 +/- 10.9 years; BMI 47.2 +/- 7.4 kg/m(2); 83.2% female, 91.8% Caucasian) underwent a preoperative psychological evaluation. At 6 months post-surgery, body mass index (BMI), % excess weight loss (%EWL), hospital readmissions, and adherence to behavioral recommendations were assessed.


RESULTS
Of the patients, 10.2% had MED, 36.7% had ED only, 24.0% had MD only, and 29.1% of patients had ND. MED patients fared worse than all other groups in dietary violations (p = 0.03), exercise habits (p = 0.05), and readmission rates (p = 0.06) but there were no group differences in either BMI change or %EWL.


CONCLUSIONS
MED patients are at-risk for poor treatment compliance following LRYGBP; however, they achieve similar weight losses 6 months postoperatively.
