AbstractBackgroundPatients with gastroparesis (Gp) may need enteral nutrition (EN) or exclusive parenteral nutrition (PN). Among patients with Gp, we aimed to (1) identify the frequency of EN and exclusive PN use and (2) explore characteristics of patients using EN and/or exclusive PN compared with those using oral nutrition (ON), including changes over 48 weeks.MethodsPatients with Gp underwent history and physical examination, gastric emptying scintigraphy, water load satiety testing (WLST), and questionnaires assessing gastrointestinal symptoms and quality of life (QOL). Patients were observed 48 weeks.ResultsOf 971 patients with Gp (idiopathic, 579; diabetic, 336; post–Nissen fundoplication, 51), 939 (96.7%) were using ON only, 14 (1.4%) using exclusive PN, and 18 (1.9%) using EN. Compared with patients receiving ON, patients receiving exclusive PN and/or EN were younger, had lower body mass index, and had greater symptom severity. Patients receiving exclusive PN and/or EN had lower physical QOL but not mental QOL or Gp‐related QOL scores. Patients receiving exclusive PN and/or EN ingested less water during WLST but did not have worse gastric emptying. Of those who had been receiving exclusive PN and/or EN, 50% and 25%, respectively, resumed ON at 48‐week follow‐up.ConclusionsThis study describes patients with Gp requiring exclusive PN and/or EN for nutrition support, who represent a small (3.3%) but important subset of patients with Gp. Unique clinical and physiological parameters are associated with this subset and provide insight into the use of nutrition support in Gp.

AbstractBackgroundUnderstanding factors that impair quality of life (QOL) in gastroparesis is important for clinical management. Aims: (a) Determine QOL in patients with gastroparesis; (b) Determine factors that impair QOL.MethodsGastroparetic patientsAQ6 underwent history and questionnaires assessing symptoms (PAGI‐SYM and Rome III), QOL (SF‐36v2 and PAGI‐QOL), depression (Beck Depression Inventory [BDI]), and anxiety (State Trait Anxiety InventoryAQ7).Key Results715 gastroparesis patients (256 diabetic (DG), 459 idiopathic (IG)) were evaluated. SF‐36 physical component (PC) score averaged 33.3 ± 10.5; 41% had impaired score <30. SF‐36 PC scores were similar between diabetic and idiopathic gastroparesis. Impaired SF‐36 PC associated with increased nausea/vomiting and upper abdominal pain subscores, acute onset of symptoms, higher number of comorbidities, use of narcotic pain medications, and irritable bowel syndrome (IBS). SF‐36 mental component (MC) score averaged 38.9 ± 13.0; 26% had impaired score <30. Poor SF‐36 MC associated with diabetic etiology, higher Beck depression inventory, and state anxiety scores. PAGI‐QOL score averaged 2.6 ± 1.1; 50% had a score of <2.6. Low PAGI‐QOL associated with higher fullness, bloating, and upper abdominal pain subscores, more depression and Trait anxiety, smoking cigarettes, need for nutritional support, progressively worsening symptoms and periodic exacerbations.Conclusions & InferencesMultiple measures show poor QOL present in gastroparesis. Several areas impacted on reduced QOL: (a) Symptoms of nausea, vomiting, and abdominal pain, as well as IBS; (b) Etiology and acute onset and progressively worsening symptoms; (c) Comorbidities and psychological factors such as anxiety and depression; (d) Patient‐related factors such as smoking. Targeting the modifiable factors may improve patient outcomes in gastroparesis.
