Abstract:
Since some years the sleeve gastrectomy, a bariatric procedure, has been applied in treatment programs for severe obesity with distinct effects regarding reduction of body weight, and low complication rates. Still, only little data is available about psychological and social variables after sleeve gastrectomy. Therefore in this survey, physical and mental wellbeing, general psychopathology, eating behaviour and body image have been examined in 31 patients undergoing bariatric surgery. Immediately before and one year after surgery the patients filled in validated questionnaires assessing the above mentioned dimensions. The %EWL (percent excess weight loss) one year after surgery is 53,9% (SD 18,6), somatic comorbidities and physical wellbeing have clearly improved. Depressiveness decreased significantly. Stress and to a smaller extent also anxiety disorders show a positive development. Pathological patterns in eating behaviour were reduced and five out of six patients presenting symptoms of an eating disorder with experience of loss of control preoperatively do not declare to have these symptoms one year later. Considering the body image, a significant decrease of negative body valuing and a significant increase of vital body dynamics have been found. The variables regarding the social environment of the patients did not change significantly. In general, the described findings do not significantly differ from the results of previous studies after Roux-en-Y gastric bypass and gastric banding.
In spite of the mainly positive outcome after bariatric surgery it became clear that one year after the intervention some patients still suffer from depressive disorders, eating attacks and other mental issues. To supply these patients with the necessary therapy a well structured, attentive follow-up is crucial. A treatment conforming to guidelines as well as individually adapted should be offered to patients when and as required.
