The Effect of Bariatric Surgery on PAI-1 Levels: A Systematic Review and Meta-analysis.

The purpose of this meta-analysis was to determine the effect of bariatric surgery on circulating PAI-1. The meta-analysis was provided by comprehensive meta-analysis (CMA) V4 software. Meta-analysis of 33 studies showed a significant decrease in circulating PAI-1 after bariatric surgery (p < 0.001). A significant reduction was observed for two types of surgery) (p < 0.001 for LSG and p < 0.001 for RYGB). Furthermore, there was a significant change in circulating PAI-1 based on the follow-up duration (p < 0.001 for follow-up < 12 months and p < 0.001 for follow-up ≥ 12). We showed that bariatric surgery changed PAI-1 level significantly and changes in BMI after surgery were not related to PAI-1 alteration. Furthermore, this result was consistent based on follow-up duration and type of surgery.
