BACKGROUND： The role of diabetes mellitus （DM） in pancreatic fistula （PF） or clinical relevant PF （CR-PF） after pancreaticoduodenectomy （PD） or pylorus-preserving pancreaticoduodenectomy （PPPD） is unclear. ...BACKGROUND： The role of diabetes mellitus （DM） in pancreatic fistula （PF） or clinical relevant PF （CR-PF） after pancreaticoduodenectomy （PD） or pylorus-preserving pancreaticoduodenectomy （PPPD） is unclear. We conducted a meta-analysis to investigate the relationship between DM and PF or CR-PF.DATA SOURCES： Embase, MEDLINE and Cochrane databases were searched systematically for relevant articles from January 2005 to June 2013. The selected studies that examined clinical risk factors of PF or CR-PF were included. We created pooled estimates for our outcomes using the random-effects model. RESULTS： Sixteen observational clinical studies were included. Pooling of PF rates from ten studies revealed that DM was associated with a decreased risk of PF （P=0.01）. CR-PF rates from 8 studies showed no significant difference between DM and control group （P=0.14）. CONCLUSIONS： DM is not a risk factor for PF in patients undergoing PD or PPPD. On the contrary, patients without DM are at a higher risk of PF because the pancreases in these patients have more fatty tissue and the pancreas is soft.展开更多
