Background
The functional aspects of obesity are increasingly recognised as a significant clinical and public health concern. Whilst there is substantial evidence for the beneficial impact of bariatric surgery on metabolic and cardiovascular disease, there is less understanding of the quantitative effect of bariatric surgery on back pain. The aim of this meta-analysis was to assess the impact of bariatric surgery on back pain in reported studies.
Methods
Medline, Embase, conference proceedings and reference lists were searched for studies assessing quantitative back pain scores both before and after bariatric surgery. The primary outcome was visual analogue score for back pain pre- and post-bariatric surgery. Secondary outcomes were change in BMI, SF-36 quality of life scores and Oswestry Disability Index (ODI) scores. Weighted mean differences (MD) were calculated for continuous outcomes.
Results
Seven studies were included in the analysis of 246 patients undergoing bariatric surgery. Mean study follow-up was between 3 and 24 months. There was a statistically significant reduction in visual analogue score for back pain following bariatric surgery (MD − 3.01; 95% CI − 4.19 to − 1.89; p < 0.001). Bariatric surgery also resulted in statistically significant improvements in BMI, SF-36 score and ODI score.
Conclusions
Bariatric surgery produces significant and quantifiable reductions in back pain. This may be commuted through reductions in axial load or improved quality of life, but further studies will improve understanding and aid preoperative counselling.
