Purpose
Delayed gastric emptying (DGE) is a common functional disorder after esophagectomy with gastric tube reconstruction. Little is known about risk factors that can predict this debilitating complication.
Methods
Patients who underwent elective esophagectomy from 2008 to 2016 in a single center were retrospectively reviewed. Diagnosis of DGE was based on clinical, radiological, and endoscopic findings. Uni- and multivariate analyses were performed to identify patient-, tumor-, and procedure-related factors that increase the risk of DGE.
Results
One hundred eighty-two patients were included. Incidence of DGE was 39.0%. Overall, 27 (14.8%) needed an endoscopic intervention. Patients in the DGE group had a longer hospital stay (p < 0.01). No differences were found for the 30-day (p = 1.0) and hospital mortality (p = 1.0). On univariate analyses, a significant influence on DGE was demonstrated for pre-existing pulmonary comorbidity (p = 0.04), an anastomotic leak (p < 0.01), and postoperative pulmonary complications (pneumonia: p = 0.02, pleural empyema: p < 0.01, and adult respiratory distress syndrome: p = 0.03). Furthermore, there was a non-significant trend toward an increased risk for DGE for the following variable: female gender (p = 0.09) and longer operative time (p = 0.09). On multivariate analysis, only female gender (p = 0.03) and anastomotic leak (p = 0.01) were significantly associated with an increased risk for DGE.
Conclusions
DGE is a frequent complication following esophagectomy that can successfully be managed with conservative or endoscopic measures. DGE did not increase mortality but was associated with increased morbidity and prolonged hospitalization. We identified risk factors that increase the incidence of DGE. However, this has to be confirmed in future studies with standardized definition of DGE.
