Background: Dyspeptic symptoms are not well correlated with gastric emptying (GE) results. Aims: To determine (a) prevalence of delayed SB transit (SBT) in patients undergoing GE scintigraphy for symptoms of gastroparesis; (b) symptoms associated with delayed SBT. Methods: Patients with symptoms of gastroparesis underwent combined GE and SBT scintigraphy (GES/SBTS). Patients ingested a mixed solid (S)‐liquid (L) meal with egg whites labeled with 500 µCi Tc‐99 m sulfur colloid and water with 125 µCi In‐111 DTPA. Retained S and L gastric activity and percent of L In‐111 activity in terminal ileum (TI) and/or cecum/colon at 6 h were determined. Patient Assessment of Gastrointestinal Symptoms (PAGI‐SYM) assessed symptoms from 0 (none) to 5 (very severe). Key Results: Of 363 patients, 174 (47.9%) had delayed S GE, 141 (38.8%) delayed L GE, and 70 (19.3%) delayed SBT. Delayed SBT was seen in 24 (6.6%) with normal S GE and 46 (12.7%) with delayed S GE. Patients with isolated delayed SBT had highest symptom scores for postprandial fullness (3.5), stomach fullness (3.4), nausea (3.2), bloating (3.2), compared to isolated delayed S GE who had highest symptom scores for postprandial fullness (3.7), nausea (3.6), stomach fullness (3.4), and early satiety (3.3). Conclusions & Inferences: Delayed SBT occurred in 19.3% of dyspeptic patients using GES/SBTS. While postprandial and stomach fullness were common to both delayed S GE and delayed SBT, early satiety was associated with delayed S GE whereas bloating was associated with delayed SBT. Thus, SBTS can augment GES to help explain some symptoms associated with dyspepsia and suspected gastroparesis. [ABSTRACT FROM AUTHOR]

Background: Symptoms of gastroparesis (Gp) can fluctuate at different times of the day. Our aims are (1) To characterize Gp symptom variability throughout the day and in relation to meals and (2) to compare the daily symptom variability in subtypes of Gp—diabetic gastroparesis (DGp) and idiopathic gastroparesis (IGp). Methods: Patients with Gp filled Patient Assessment of Gastrointestinal Symptoms (PAGI‐SYM) and completed a modified GCSI‐DD seven times a day (GCSI‐Throughout the Day [GCSI‐TTD]; before and after meals, and before going to bed) over a 2‐week period. Key Results: A total of 44 patients participated (86% females), including 29 (66%) with IGp, 13 (30%) with DGp, and 2 (4%) with postsurgical Gp. Using the GCSI‐TTD, patients with Gp reported significant postprandial worsening of overall symptom severity, as well as severities of nausea, early satiety, stomach fullness, and abdominal pain. Patients also had progressive worsening of the overall symptom severity, early satiety, stomach fullness, and abdominal pain during the day; however, nausea severity did not differ during the day. Number of vomiting and retching episodes did not show significant variations postprandially or during the day. Patients with IGp had greater symptom severity throughout the day and greater postprandial increase in symptoms compared to patients with DGp. Conclusions and Inferences: Patients with Gp experience postprandial worsening of overall symptom severity, as well as severities of nausea, early satiety, stomach fullness, and abdominal pain. These symptoms also progressively worsen during the day, except for the severity of nausea which persists throughout the day. Understanding the symptom variability in patients with Gp throughout the day and postprandially may be useful in treatment of patients with Gp. [ABSTRACT FROM AUTHOR]
