Background and Aims
Retained gastric food (RGF) identified during esophagogastroduodenoscopy (EGD) is often attributed to gastroparesis. This retrospective study evaluated the prevalence of RGF, risk factors for RGF, and the association between RGF and delayed gastric emptying (GE).
Methods
The prevalence and odds ratios for RGF in patients with structural foregut abnormalities or medical risk factors for delayed GE were determined from 85,116 EGDs performed between 2012 and 2018. The associations between RGF, delayed GE, and medical comorbidities were evaluated in 2991 patients without structural abnormalities who had undergone EGD and gastric emptying scintigraphy. The relationship between medication use and RGF was evaluated in 249 patients without structural or medical risk factors for RGF.
Results
RGF was identified during 3% of EGDs. The odds of RGF were increased in patients with type 1 diabetes (12%, OR 1.7, P ≤ 0.001), type 2 diabetes (6%, OR 1.4, P ≤ 0.001), gastroparesis (14%, OR 4.8, P ≤ 0.001), amyloidosis (5%, OR 1.7, P ≤ 0.001), and structural foregut abnormalities (6%, OR 2.6, P ≤ 0.001). Overall, the PPV of RGF for delayed GE was 55%. However, the PPV varied from 32% in patients without risk factors to 79% in patients with type 1 diabetes. Opioids, cardiovascular medications, and acid suppressants were associated with RGF.
Conclusions
RGF is common during EGD. The PPV of RGF for delayed GE varies depending on underlying risk factors (type 1 diabetes, type 2 diabetes, gastroparesis, and amyloidosis). Acid suppressants or antacids, cardiovascular medications, and opioids are associated with RGF independent of delayed GE.
