The average impact of bariatric surgery on quality of life corresponded to an effect size of 0.88 ( 95 % CI : 0.80 - 0.96 ) , indicating that bariatric surgery has a significant positive influence on quality of life in general .
The impact varied considerably across studies with bariatric surgery showing a significantly greater positive influence on physical quality of life compared to mental quality of life .
Bariatric surgery is effective in improving quality of life , especially when looking at physical well-being .
Greater focus on the psychological well-being of the person undergoing surgery for obesity may lead to a better post-surgery prognosis for more people
This study aims to review the obesity literature in order to assess the impact of bariatric surgery on quality of life and the between- study variation by examining the st and ardized mean magnitude of effect in change in the levels of quality of life .
Treating morbid obesity with laparoscopic adjustable gastric banding.
BACKGROUND Morbid obesity results in multiple comorbidities and an increased mortality rate . The National Institutes of Health has stated that surgery is the most effective long-term therapy ; therefore , we evaluated a laparoscopically implantable adjustable gastric b and . METHODS We review ed 2 multicenter prospect i ve , open-label , single-arm surgical trials -- trial A ( 3 years ) and trial B ( 1 year)--with ongoing safety follow-up . These trials were conducted in United States community and university hospitals ( trial A = 8 sites and trial B = 12 sites ) . Trial A comprised 292 subjects ( mean + /- SD preoperative weight : 133 kg + /- 24.4 ) , and trial B comprised 193 subjects ( 129 kg + /- 20.8 ) . Intervention included placement of a constrictive , adjustable b and around the upper stomach to limit food intake and induce weight loss . Main outcome measures were the primary efficacy end point of weight loss . Secondary end-points were change in quality -of-life , safety parameters , and complications , including b and slippage , reoperation , and device explantation . RESULTS In the 2 trials , 485 devices were implanted ( 92 % laparoscopically ) , and no deaths occurred . Of the patients in trial A , 206 ( 70.5 % ) completed the 3-year follow-up , and 142 ( 73.6 % ) of patients in trial B completed the 1-year follow-up . Weight-loss results , using the last value carried forward , for all 292 patients in trial A and all 193 patients in trial B demonstrated a change in mean body mass index ( kg/m2 ) + /- SD from 47.4 + /- 7.0 to 39.0 + /- 7.3 in trial A and from 46.7 + /- 7.8 to 38.4 + /- 7.6 in trial B subjects at 1 year ( P < .001 for both trials A and B ) , with minimal further change at 3 years ( 39.0 + /- 8.5 ) in trial A subjects . The percentage of initial body weight lost at 1 year was 17.7 % + /- 9.4 % for trial A subjects and 18.2 % + /- 8.9 % for trial B subjects , whereas the 3-year total for trial A subjects was 18.3 % + /- 13.1 % . At 1 year , 76 % of patients in trial A and 66 % of patients in trial B had complications , mostly related to upper gastrointestinal symptoms . By 9 years after surgery , 33 % ( 96 of 292 ) of trial A subjects had their devices explanted because of complications or inadequate weight loss . CONCLUSIONS These first-generation implantable adjustable gastric b and results suggest that this is a viable bariatric surgery therapeutic option for the treatment of obesity
