Primary versus secondary delayed gastric emptying (DGE) grades B and C of the International Study Group of Pancreatic Surgery after pancreatoduodenectomy: a retrospective analysis on a group of 132 patients
2015
Delayed gastric emptying (DGE) is a common complication after pancreaticoduodenectomy (PDD) significantly contributing to post-operative morbidity. Clinical risk factors for DGE occurrence after PDD remain controversial. From January 2004 to December 2011, a total of 132 patients underwent PDD for either malignancies (73.5 %) or benign diseases (26.5 %) in one single universitary center. Post-operative mortality and morbidity were, respectively, 3 and 44.7 %. DGE has been defined in accordance with the International Study Group of Pancreatic Surgery (ISGPS) classification. DGE was distinguished in primary or secondary. Factors associated with grades B and C of DGE, based on severity and clinical impact, were assessed by means of univariate and multivariate analysis. Thirty-eight patients (28.8 %) had clinical DGE grade B or C. Post-operative complications (pancreatic fistula and/or hemorrhage or anastomotic leak) were reported in 25 out of the 38 patients (65.8 %, secondary DGE), while in 13 patients it was not associated to any other complication (34.2 %, primary DGE). Post-operative complications (pancreatic fistula and hemorrhage) appeared to be the most important predictive factor for Grade B or C DGE.
