Psychosocial functioning before and after laparoscopic adjustable gastric banding: a cross-sectional study

Background: The aim of this cross-sectional study was to examine short and long-term physical, mental and, particularly, social quality of life (GoL) of patients with severe obesity after laparoscopic adjustable gastric banding (LAGB). Methods: 250 patients (221 female, 29 male, mean age 39.6 years, age range 22-61) filled out questionnaires to evaluate several aspects of QoL: 93 patients before LAGB, 48 with a follow-up duration of 8 through 24 months, and 109 patients 25 through 68 months after LAGB. Results: Compared with patients before surgery, patients after surgery, in both follow-up groups, had lower weight and co-morbidity, felt and functioned better on physical and psychological dimensions of OoL, and on most aspects of social QoL. No significant differences emerged between the two postoperative groups. On average, the postoperative OoL was still lower than the age norm group. Mutual correlations between OoL and weight outcome were very low up to 2 years after surgery, but more strongly associated >2 years after surgery Conclusion: LAGB could be a long-term solution to morbid obesity with regard to both weight and QoL outcome. The findings of our study emphasize the importance of including social QoL variables in outcome research. They further suggest that when the follow-up duration increases, especially in patients who are single, intervention and consultation should be simultaneously directed at weight and psychosocial variables.
