Abstract

Objectives

This study investigates the factors that could influence the development of delayed gastric emptying (DGE) after pancreatoduodenectomy (PD). Delayed gastric emptying is a common complication after PD. The postoperative course is affected by a lengthened hospital stay, a decrease of the patients' quality of life, and a delayed adjuvant treatment.

Methods

From January 2000 to December 2012, 257 patients underwent PD in the same center. Forty-six variables were retrospectively extracted from medical records. Delayed gastric emptying (grades A, B, and C) was defined by the International Study Group of Pancreatic Surgery classification. Univariate and multivariate analyses were performed to identify factors associated with DGE.

Results

Delayed gastric emptying occurred in 133 patients (51.8%), 89 grade A (66.9%), 27 grade B (20.3%), and 17 grade C (12.8%). Biliary fistula (odds ratio [OR], 8.87; 95% confidence interval [CI], 2.07–37.99, P = 0.003), sepsis (OR, 8.02; 95% CI, 3.22–19.99; P < 0.0001), and intra-abdominal collection (OR, 3.43; 95% CI, 1.06–11.06; P = 0.039) were identified as independent risk factors for DGE, whereas pancreaticogastrostomy (OR, 0.32; 95% CI, 0.16–0.64; P < 0.001) decreased the occurrence of DGE.

Conclusions

Delayed gastric emptying was linked to the occurrence of postoperative intra-abdominal complications, and reconstruction by pancreaticogastrostomy was beneficial by decreasing its incidence.
