The factors associated with delayed gastric emptying (DGE) after a pancreaticoduodenectomy (PD) are not definitively known.Methods:
From November 2011 through to May 2012, data were prospectively collected on 711 patients undergoing a pancreaticoduodenectomy or total pancreatectomy as part of the American College of Surgeons-National Surgical Quality Improvement Program Pancreatectomy Demonstration Project. Bivariate and multivariate models were employed to determine the factors that predicted DGE.Results:
In the 711 patients, the overall rate of DGE was 20.1%. In a bivariate analysis, intra-operative factors such as pylorus-preservation (47.1% versus 43.7%, P = 0.40), intra-operative drain placement (85.5%, versus 85.1%, P = 0.91) and an antecolic compared with a retrocolic gastrojejunostomy (60.1% versus 65.1%, P = 0.26) were not different between the DGE and no DGE groups. Pancreatic fistula formation (31.2% versus 10.1%), post-operative sepsis (21.7% versus 7.0%), organ space surgical site infection (SSI) (23.9% versus 7.9%), need for percutaneous drainage (23.0% versus 10.6%) and reoperation (10.6% versus 3.1%) were higher in patients with DGE (P < 0.0001). In a multivariable model, only pancreatic fistula, post-operative sepsis and reoperation were independently associated with DGE.Discussion:
In this multicentre study, only post-operative complications were associated with DGE. Neither pylorus preservation nor route of enteric reconstruction (antecolic versus retrocolic) was associated with delayed gastric emptying.
