Costs and Complications: Delayed Gastric Emptying after Pancreaticoduodenectomy

Abstract

Postoperative delayed gastric emptying (DGE) is a very common complication after a pancreaticoduodenectomy (PD). This along with other complications can lead to increased health-care costs. This study investigates the costs and length of stay (LOS) associated with these. A retrospective study of 131 patients undergoing PD between 2000 and 2016 at Loma Linda University Health was performed. Chi-squared test was used to determine statistically significant differences between patients with and without DGE (according to the definition of the International Study Group of Pancreatic Surgery). Multiple logistic and linear regression analyses were performed to obtain adjusted odds ratios for variables of interest in association with DGE and relationship to LOS. Of 150 patients undergoing PD, 131 patients with tumors were analyzed. The overall incidence of DGE was 56 per cent. No pre- or postoperative factors were associated with increased risk of DGE. The median LOS for patients with DGE was 15 days versus 9 days for patients without DGE. Patients with DGE added $21,198 to the overall cost of hospitalization. Fourteen patients (10.7%) were readmitted, of whom 11 were because of DGE. Further studies assessing the utility of intraoperative G-tube placement in decreasing hospital costs and readmissions are needed.
