RESUMO
BACKGROUND: Non-compliant patients fail to match their behavior to the clinical prescription. Laparoscopic adjustable gastric banding requires strict compliance with surgical and dietary advice. Failure to attend follow-up appointments and the persistent consumption of calorie-dense liquid foods are associated with poor weight loss and postoperative complications. Prediction of "poor compliers" would enhance candidate selection and enable specific interventions to be targeted. METHODS: 9 poor compliers were identified and compared with 9 fully compliant controls. Case-notes were analyzed retrospectively. RESULTS: Cases were found to graze on foods and eat more in response to negative affects. They were reluctant to undergo psychiatric assessment, viewed the band as responsible for weight loss, and aroused caution in the psychiatric evaluator. Poor compliance was not associated with binge eating, purging, impulsivity or psychiatric illness. CONCLUSIONS: Unrealistic expectations and anxiety are known to predict non-adherence. Constant negative affects may be self-modulated by grazing. The results are explored in the context of Self-efficacy Theory, a socio-cognitive account of illness behavior.

BACKGROUND: Laparoscopic adjustable gastric banding is increasingly being performed in morbidly obese individuals for weight loss. Some patients develop pouch dilatation as a postoperative complication that limits the utility of the procedure. Surgical variables are poor predictors of this complication. 5 patients from a series of 157 who underwent LAGB at a single center developed the condition. METHODS: Psychiatric and surgical case-notes were analyzed retrospectively for the presence of operationally defined psychiatric disorders and compared to 10 controls from the same population. RESULTS: Cases were significantly more likely to have past or current binge eating, emotionally triggered eating with reduced awareness of the link, a history of affective disorder, reduced sexual functioning and successful preoperative weight loss. No difference between groups was observed for compliance with orlistat, childhood sexual abuse, relationships with parents, history of bulimia nervosa, rate of band inflation or preoperative BMI. CONCLUSIONS: Psychological factors may be better predictors of pouch dilatation than biomedical variables. Disordered eating can be an attempt to modulate negative emotions. Pouch dilatation may be a consequence of this eating behavior.
