Abstract:
Objective:To systematically evaluate the effect of bariatric and metabolic surgery on bone metabolism in obese patients.Methods:Search terms for the present meta-analysis included "bariatric surgery, metabolic surgery, sleeve gastrectomy, gastric bypass, bone metabolic indicators, bone mineral density", both in English and corresponding Chinese. PubMed, WOS, Cochrane, CNKI, and VIP databases were searched for longitudinal studies from the establishment of the database to September 20, 2022. The data on bone mineral density and bone metabolic markers in obese patients before and after bariatric surgery were extracted. RevMan5.4 and Stata17.0 software were used for Meta-analysis.Results:A total of 8 clinical studies with 420 patients were included. The results of the meta-analysis showed that compared with the preoperative baseline, lumbar spine bone mineral density ( WMD=0.05, 95% CI: -0.00~0.1), femoral neck bone mineral density( WMD=0.10, 95% CI: 0.05-0.15), hip bone mineral density( WMD=0.14, 95% CI: 0.10-0.17), and serum vitamin D 3 ( WMD=-4.87, 95% CI: -6.34--3.40)were decreased, while parathyroid hormone ( WMD=10.04, 95% CI: 5.32-14.76) was elevated after surgery. Conclusions:Current evidence demonstrates that metabolic and bariatric surgery can lead to decreased bone mineral density and impairs in bone metabolic markers early after surgery. Roux-en-Y gastric bypass surgery cause more adverse effects on bone metabolism than sleeve gastrectomy. The results imply that all patients undergoing metabolic and bariatric surgery should be monitored for bone metabolism and routinely take vitamin D and calcium supplements.
