Hollis E, Murray HB, Parkman HP. Relationships among symptoms of gastroparesis to those of avoidant/restrictive food intake disorder in patients with gastroparesis. Neurogastroenterol Motil 2024; 36:e14725. [PMID: 38062502 PMCID: PMC10842788 DOI: 10.1111/nmo.14725] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/18/2023] [Revised: 11/03/2023] [Accepted: 11/28/2023] [Indexed: 01/25/2024]
Abstract
BACKGROUND Patients with symptoms of gastroparesis (Gp) often reduce food intake in attempt to manage their symptoms. Up to 40% of adults with Gp have been reported to have symptoms of a non-body image-based eating disorder, avoidant/restrictive food intake disorder (ARFID). However, whether ARFID symptoms precede or follow the diagnosis of Gp is unknown. METHODS From January 2021 to January 2022, consecutive adult patients with Gp at an academic center completed self-report surveys for Gp symptom severity (patient assessment of upper gastrointestinal symptoms; PAGI-SYM) and for ARFID (nine-item ARFID screen; NIAS). KEY RESULTS One hundred and seven patients (age 45.4 ± 17.2 yrs, 84.1% female, BMI 26.4 ± 7.3) with Gp (4-h gastric retention 33.5 ± 21.8%) were included. Eighty-two of the 107 Gp patients (77%) screened positive for ARFID. Positive ARFID screen was most often on the NIAS appetite subscale (84%) and fear subscale (76%), with a lower positive screen rate on the picky subscale (45%). Of the Gp who screened positive for ARFID, 38% reported that eating difficulties came after their Gp diagnosis, whereas 17% reported that eating difficulties preceded their Gp diagnosis, and 15% reported that both began at the same time. CONCLUSIONS Many (77%) patients with Gp screened positive for ARFID. In Gp patients with ARFID, the Gp diagnosis was more likely to precede the development of eating difficulties. Thus, a subset of patients with Gp may be at risk for developing ARFID. Further longitudinal research is needed to confirm findings and identify risk factors.

Effect of DA-9701 on the Gastrointestinal Motility in the Streptozotocin-Induced Diabetic Mice. J Clin Med 2021; 10:jcm10225282. [PMID: 34830563 PMCID: PMC8623860 DOI: 10.3390/jcm10225282] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 11/04/2021] [Accepted: 11/08/2021] [Indexed: 12/11/2022] Open
Abstract
Background: Compared to the general population, diabetic patients experience more frequent episodes of gastrointestinal (GI) motility dysfunction, owing to the disruption of functional innervations. DA-9701 is a new prokinetic agent formulated from the extracts of Pharbitidis semen and Corydalis tuber. Aim: To investigate the effect of DA-9701 on GI motility in an animal model of streptozotocin (STZ)-induced diabetes. Methods: Diabetes was induced in mice by intraperitoneal injection of STZ (40 mg/kg of body weight in 0.1 M citrate buffer) for 3 days. Diabetic mice were divided into four groups and administered DA-9701 in different doses (1, 3, and 10 mg/kg) or placebo for 2 weeks. Intestinal transit was assessed using charcoal meal movement. GI isometric contraction was measured by applying an isometric force transducer on a circular muscle strip of the antrum, ileum, and proximal colon of sacrificed mice. Gastric emptying rate was evaluated by measuring the dye percentage remaining in the stomach relative to the total dye amount recovered in a standardization group of mice. Results: Body weight and antral and small intestinal motility were less in diabetic mice than in control mice, and colonic motility was similar in both. DA-9701 showed a dose-dependent increase in the amplitude of spontaneous phasic contractions in the antrum, ileum, and colon in diabetic mice without influencing body weight or blood glucose levels. The degree of improvement was comparable between diabetic and control mice. Intestinal transit was significantly more delayed in diabetic mice than in controls (43 ± 7% vs. 67 ± 8%, p < 0.05); however, DA-9701 restored the delayed intestinal transit more effectively compared to placebo (75% vs. 50%). The gastric emptying rate was significantly more delayed in diabetic mice than in controls (43 ± 10% vs. 62 ± 12%, p < 0.05), and was improved by DA-9701 in a dose-dependent manner (50%, 55%, and 60% in mice treated with 1, 3, and 10 mg/kg of DA-9701, respectively, vs. 43% in placebo-treated and 60% in control mice). Conclusions: DA-9701 improved GI contractility without affecting blood sugar and body weight in diabetic mice. DA-9701 could improve the decreased GI motility and clinical symptoms in progressive diabetic patients.

Neurogastroenterol Motil 2021; 33:e13991.

Abstract
BACKGROUND A novel technique to assess gastric motility by measuring the pressure in a low-volume intragastric balloon was developed to monitor (disordered) motility. We previously showed that this technique allows measuring pharmacologically induced inhibition of motility. In this study, we assessed whether it is possible to measure pharmacologically induced stimulation of gastric motility using 200 mg erythromycin. Erythromycin is a highly effective stimulator of gastric emptying and contractility. METHODS After an overnight fast, a nasogastric balloon catheter was introduced in healthy subjects. After inflation with 120 ml of air, the catheter was connected to a pressure sensor. Intraballoon pressure was continuously recorded for 4 h. After a baseline recording of 2 h, 200 mg erythromycin was infused intravenously over 20 min while the recording continued for 2 h. Epigastric symptoms were surveyed on 100-mm visual analogue scales. Motility was quantified from the pressure recording as a gastric balloon motility index. Wilcoxon signed-rank tests were performed. Data are shown as median (interquartile range). KEY RESULTS Six subjects were enrolled and five completed the procedures (age: 28 (25-29) years, body mass index: 24.0 (23.8-24.5) kg m-2 ). One subject could not tolerate tube placement. Bloating, nausea, and epigastric sensation scores were 0 (0-3), 0 (0-1), and 1 (0-1) mm, respectively. Erythromycin significantly increased the motility index from 0.48 (0.41-0.51) to 0.79 (0.70-0.82) (p = 0.03). CONCLUSIONS AND INFERENCES Gastric motility assessed via pressure measurement in a low-volume intragastric balloon is able to detect pharmacologically stimulated motility in healthy subjects, which further validates this technique.

High Prevalence of Small Intestinal Bacterial Overgrowth among Functional Dyspepsia Patients. Dig Dis 2020; 39:382-390.

Abstract
BACKGROUND Small intestinal bacterial overgrowth (SIBO), characterized by either increased numbers or presence of colonic type bacteria in the small bowel has been previously described in functional dyspepsia (FD), based on breath testing. In this study, we aim to examine the prevalence of SIBO among FD patients using small bowel aspirate culture. METHODS We prospectively enrolled outpatients fulfilling Rome IV criteria for FD. Severity of symptoms was graded using the patient assessment of upper gastrointestinal symptom severity index (PAGI-SYM) questionnaire. Patients underwent upper gastrointestinal endoscopy and duodenal fluid was aspirated in sterile traps. SIBO was defined as ≥103 colony forming units/mL of duodenal aspirate and/or presence of colonic type bacteria. Patients undergoing gastroscopy due to gastroesophageal reflux symptoms - control group (CG) - and patients with irritable bowel syndrome (IBS) fulfilling Rome IV criteria were also recruited. RESULTS We enrolled 227 FD subjects, 30 CG, and 90 IBS patients. Among FD patients, 144 (63.4%), 64 (28.2%), and 19 (8.4%) had postprandial distress syndrome (PDS), epigastric pain syndrome (EPS), and overlapping PDS-EPS syndrome, respectively. SIBO prevalence was 20.8%, 12.5%, and 31.6% among PDS, EPS, and overlapping PDS-EPS FD subtypes, respectively. Overall, SIBO prevalence was significantly higher in FD (44/227 [19.4%]) compared to CG (1/30 [3.3%]) (p = 0.037) and similar to IBS (44/227 [19.4%] vs. 15/90 [16.7%], p = 0.63) subjects. SIBO presence was associated neither with total nor with any subscale score of the PAGI-SYM questionnaire. CONCLUSION In a cohort of Greek FD patients, SIBO prevalence was similar to that of IBS subjects and higher compared to that of controls.

Codeine delays gastric emptying through inhibition of gastric motility as assessed with a novel diagnostic intragastric balloon catheter. Neurogastroenterol Motil 2020; 32:e13733. [PMID: 31595608 DOI: 10.1111/nmo.13733] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2019] [Revised: 09/13/2019] [Accepted: 09/16/2019] [Indexed: 02/08/2023]
Abstract
BACKGROUND The use of opioids as analgesic is on the rise, despite their inhibitory effect on gastric emptying. A novel feeding catheter with integrated intragastric balloon was developed to continuously assess gastric motility, enabling to investigate the effect of opioids on motility and emptying simultaneously. We aimed to discriminate normal and pharmacologically impaired gastric motility and its impact on gastric emptying in healthy adults. METHODS The VIPUN Gastric Monitoring System comprises a nasogastric balloon catheter and a monitoring unit. In a four-way randomized, single-blinded, cross-over study, subjects received either placebo or 58.8 mg codeine phosphate in combination with either an uninflated or an inflated (180 mL) balloon catheter. Motility-induced pressure changes were recorded for 6 hours. During the first 2 hours, nutrients were infused (225 kcal, 75 mL/h). Gastric emptying was assessed with a 13 C-octanoate breath test and expressed as gastric half-emptying time (GET½). An algorithm, designed to detect phasic contractility, converted pressure changes to a gastric balloon motility index (GBMI). Results are presented as mean(SD). KEY RESULTS Eighteen subjects completed the investigation (32(13) years, 22(2) kg/m2 ). After codeine, GBMI was lower (0.31(0.16)) and GET½ was longer (233(57) minutes) compared with placebo (GBMI: 0.48(0.15), P < .01 and GET½: 172(12) minutes, P < .001). Within-subject ΔGET½ correlated significantly with ΔGBMI (r = -0.77 and P < .001). CONCLUSIONS AND INFERENCES The VIPUN Gastric Monitoring System allowed to assess gastric motility safely and continuously. The correlation between pharmacologically decreased gastric emptying and motility indicates a strong link between both. Gastric motility, measured with this innovative device, can be an indicator for gastrointestinal intolerance.

Abstract
OBJECTIVES Prokinetics are considered the preferred treatment option for gastroparesis, but evidence of their efficacy is scarce. Prucalopride, a selective 5-hydroxytryptamine 4 receptor agonist used in the treatment of constipation, is able to enhance the gastric emptying rate. In a double-blind, randomized, placebo-controlled crossover study, we evaluated the efficacy of prucalopride to improve the gastric emptying rate and symptoms in patients with gastroparesis. METHODS Thirty-four patients with gastroparesis (28 idiopathic, 7 men, mean age 42 ± 13 years) were evaluated in a double-blind crossover trial of 4-week treatment periods with placebo or prucalopride 2 mg q.d., separated by 2 weeks of washout. The primary end point was the change in symptom severity, assessed by the Gastroparesis Cardinal Symptom Index; secondary end points comprised the Patient Assessment of Upper Gastrointestinal Disorders-Symptom Severity Index, the Patient Assessment of Upper Gastrointestinal Disorders-Quality of Life, and daily diaries, and the gastric emptying rate was assessed by the C-octanoic acid breath test. RESULTS Three patients were lost to follow-up. One serious adverse event occurred (small bowel volvulus in the prucalopride group), and 3 patients dropped out because of adverse events of nausea and headache (all prucalopride). For the entire patient group, compared with placebo, prucalopride significantly improved the total Gastroparesis Cardinal Symptom Index (1.65 ± 0.19 vs 2.28 ± 0.20, P < 0.0001) and the subscales of fullness/satiety, nausea/vomiting, and bloating/distention. Prucalopride significantly improved the overall Patient Assessment of Upper Gastrointestinal Disorders-Quality of Life score (1.15 ± 0.16 vs 1.44 ± 0.16, P < 0.05) and the domains of clothing and diet. The gastric half emptying time was significantly enhanced by prucalopride compared with placebo and baseline (98 ± 10 vs 143 ± 11 and 126 ± 13 minutes, P = 0.005 and <0.001, respectively). These significant improvements were also found when considering only the idiopathic gastroparesis subgroup. DISCUSSION In a cohort of patients with predominantly idiopathic gastroparesis, 4 weeks of prucalopride treatment significantly improved symptoms and quality of life and enhanced gastric emptying compared with placebo.

Abstract
BACKGROUND The relationship between delayed gastric emptying and upper GI symptoms (UGI Sx) is controversial. OBJECTIVE To assess association between gastric emptying and UGI Sx, independent of treatment. DESIGN We performed a systematic review and meta-analysis of the literature from 2007 to 2017, review of references and additional papers identified by content expert. We included studies evaluating the association between gastric emptying and nausea, vomiting, early satiety/postprandial fullness, abdominal pain and bloating. Covariate analyses included optimal gastric emptying test method, gastric emptying type (breath test or scintigraphy) and patient category. Meta-regression compared the differences based on type of gastric emptying tests. RESULTS Systematic review included 92 gastric emptying studies (26 breath test, 62 scintigraphy, 1 ultrasound and 3 wireless motility capsule); 25 of these studies provided quantitative data for meta-analysis (15 scintigraphy studies enrolling 4056 participants and 10 breath test studies enrolling 2231 participants). Meta-regression demonstrated a significant difference between optimal and suboptimal gastric emptying test methods when comparing delayed gastric emptying with nausea and vomiting. On evaluating studies using optimal gastric emptying test methodology, there were significant associations between gastric emptying and nausea (OR 1.6, 95% CI 1.4 to 1.8), vomiting (OR 2.0, 95% CI 1.6 to 2.7), abdominal pain (OR 1.5, 95% CI 1.0 to 2.2) and early satiety/fullness (OR 1.8, 95% CI 1.2 to 2.6) for patients with UGI Sx; gastric emptying and early satiety/fullness in patients with diabetes; gastric emptying and nausea in patients with gastroparesis. CONCLUSIONS The systematic review and meta-analysis supports an association between optimally measured delayed gastric emptying and UGI Sx.

Abstract
BACKGROUND AND AIM Asian populations have relatively lower prevalence of gastroesophageal reflux disease and tend to exhibit symptoms of prolonged gastric retention. However, it remains unknown if slower gastric emptying influences its features in Asian countries. We prospectively assessed the potential implications of slower gastric emptying in an Asian-Pacific cohort of gastroesophageal reflux disease by a hospital-based survey. METHODS One hundred fifty-two patients of gastroesophageal reflux disease complete the scintigraphic measurement of solid phase of gastric emptying. Clinical symptoms and psychological stress are recorded by self-report questionnaire. The status of Helicobacter pylori infection, blood level of pepsinogen I, and I/II ratio are assessed. RESULTS Forty-seven percent and 28% of the patients have slower gastric emptying rate, depending on the incremental defined cut-off values of slower gastric emptying, respectively. Multiple logistic regression analysis indicates that older age and depression score are independently related to slower gastric emptying. Subgroup analysis discloses that patients with slower gastric emptying and higher depression score tend to present with non-erosive esophagitis whereas higher body mass index level and male gender in patients with normal gastric emptying predict the presence of erosive reflux disease. CONCLUSIONS Our study cohort of Asian patients indicates distinctive clinical implications of slower gastric emptying in patients with gastroesophageal reflux disease.

Abstract
Gastroparesis and functional dyspepsia are 2 of the most common gastric neuromuscular disorders. These disorders are usually confused, having both similarities and differences. The pathophysiology of these disorders involves abnormal gastric motility, visceral hypersensitivity, mucosal inflammation, and various cellular changes. Both disorders have similar symptoms such as epigastric pain or discomfort, early satiety, and bloating. If patients suspected of having either gastroparesis or functional dyspepsia present with upper gastrointestinal symptoms, they should undergo upper endoscopy to exclude an alternative organic cause. Although the gastric emptying rate is frequently assessed during the clinical workup of patients with gastroparesis or functional dyspepsia, the correlation between gastric emptying and the symptoms is generally poor. Once the diagnosis of gastroparesis or functional dyspepsia is made, treatment should focus on the predominant symptom. Recently, various treatment modalities have been developed and validated. Prokinetic agents are generally used as treatment for both gastroparesis and functional dyspepsia. Acid-suppressive therapy, Helicobacter pylori eradication, and use of drugs that enhance gastric accommodation are employed for functional dyspepsia. Psychoactive drugs are also effective in symptom control. For gastroparesis, antiemetic agents, ghrelin receptor agonists, and serotonergic agents are used aside from prokinetic agents. Acupuncture and gastric electrical stimulation can be attempted. In severe cases, endoscopic and surgical interventions are considered for symptom control.

Abstract
BACKGROUND Current investigations of gastric emptying rarely identify the cause of symptoms or provide a definitive diagnosis in patients with dyspepsia. This study assessed gastric function by magnetic resonance imaging (MRI) using the modular "Nottingham test meal" (NTM) in healthy volunteers (HVs). METHODS The NTM comprises (a) 400 mL liquid nutrient (0.75 kcal/mL) labeled with Gadolinium-DOTA and (b) an optional solid component (12 agar-beads [0 kcal]). Filling sensations were documented. MRI measurements of gastric volume, emptying, contraction wave frequency, and secretion were obtained using validated methods. KEY RESULTS Gastric function was measured in a population of 73 HVs stratified for age and sex. NTM induced moderate satiety and fullness. Labeled fluid was observed in the small bowel in all subjects after meal ingestion ("early-phase" GE). Secretion was rapid such that postprandial gastric content volume was often greater than meal volume (GCV0 > 400 mL), and there was increasing dilution of the meal during the study (P < 0.001). Gastric half-time was median 66-minutes (95% reference interval 35 to 161-minutes ["late-phase" GE]). The number of intact agar beads in the stomach was 7/12 (58%) at 60-minutes and 1/12 (8%) at 120-minutes. Age, bodyweight and sex had measurable effects on gastric function; however, these were small compared to inter-individual variation for most metrics. CONCLUSIONS AND INFERENCES Reference intervals are presented for MRI measurements of gastric function assessed for the mixed liquid/solid NTM. Studies in patients will determine which metrics are of clinical value and also whether the reference intervals presented here offer optimal diagnostic sensitivity and specificity.

Abstract
BACKGROUND Functional dyspepsia (FD), a heterogeneous disorder, involves multiple pathogenetic mechanisms. Developing treatments for FD has been challenging. We performed a randomized, placebo-controlled, double-blind clinical trial to determine the efficacy of rikkunshito, a Japanese herbal medicine, in FD patients. METHODS FD patients (n = 192) who met the Rome III criteria without Helicobacter pylori infection, predominant heartburn, and depression were enrolled at 56 hospitals in Japan. After 2 weeks of single-blind placebo treatment, 128 patients with continuous symptoms were randomly assigned to 8 weeks of rikkunshito (n = 64) or placebo (n = 61). The primary efficacy endpoint was global assessment of overall treatment efficacy (OTE). The secondary efficacy endpoints were improvements in upper gastrointestinal symptoms evaluated by the Patient Assessment of Upper Gastrointestinal Disorders-Symptom Severity Index (PAGI-SYM), the Global Overall Symptom scale (GOS), and the modified Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease (m-FSSG), and psychological symptoms evaluated by the Hospital Anxiety and Depression Scale (HADS). KEY RESULTS Rikkunshito increased OTE compared to placebo at 8 weeks (P = .019). Rikkunshito improved upper gastrointestinal symptoms (PAGI-SYM, GOS, and m-FSSG) at 8 weeks, especially postprandial fullness/early satiety (P = .015 and P = .001) and bloating (P = .007 and P = .002) of the PAGI-SYM subscales at 4 weeks and 8 weeks. Improvement of HADS at 8 weeks (P = .027) correlated with those of PAGI-SYM (r = .302, P = .001), GOS (r = .186, P = .044), and m-FSSG (r = .462, P < .001), postprandial fullness/early satiety (r = .226, P = .014), dyspepsia (r = .215, P = .019), and PDS (r = .221, P = .016). CONCLUSION & INFERENCES Rikkunshito may be beneficial for FD patients to simultaneously treat gastrointestinal and psychological symptoms.

Abstract
BACKGROUND Current investigations of stomach function are based on small test meals that do not reliably induce symptoms and analysis techniques that rarely detect clinically relevant dysfunction. This study presents the reference intervals of the modular "Nottingham test meal" (NTM) for assessment of gastric function by gamma scintigraphy (GSc) in a representative population of healthy volunteers (HVs) stratified for age and sex. METHODS The NTM comprises 400 mL liquid nutrient (0.75 kcal/mL) and an optional solid component (12 solid agar-beads (0 kcal). Filling and dyspeptic sensations were documented by 100 mm visual analogue scale (VAS). Gamma scintigraphy parameters that describe early and late phase Gastric emptying (GE) were calculated from validated models. KEY RESULTS Gastric emptying (GE) of the liquid component was measured in 73 HVs (male 34; aged 45±20). The NTM produced normal postprandial fullness (VAS ≥30 in 41/74 subjects). Dyspeptic symptoms were rare (VAS ≥30 in 2/74 subjects). Gastric emptying half-time with the Liquid- and Solid-component -NTM was median 44 (95% reference interval 28-78) minutes and 162 (144-193) minutes, respectively. Gastric accommodation was assessed by the ratio of the liquid-NTM retained in the proximal:total stomach and by Early phase emptying assessed by gastric volume after completing the meal (GCV0). No consistent effect of anthropometric measures on GE parameters was present. CONCLUSIONS AND INFERENCES Reference intervals are presented for GSc measurements of gastric motor and sensory function assessed by the NTM. Studies involving patients are required to determine whether the reference interval range offers optimal diagnostic sensitivity and specificity.

Abstract
BACKGROUND Current investigations of stomach function are based on small test meals that do not reliably induce symptoms and analysis techniques that rarely detect clinically relevant dysfunction. This study introduces the large 'Nottingham Test Meal' (NTM) for assessment of gastric motor and sensory function by non-invasive imaging. METHODS NTM comprises 400 mL liquid nutrient (0.75 kcal/mL) and 12 solid agar-beads (0 kcal) with known breaking strength. Gastric fullness and dyspeptic sensations were documented by 100 mm visual analogue scale (VAS). Gastric emptying (GE) were measured in 24 healthy volunteers (HVs) by gastric scintigraphy (GS) and magnetic resonance imaging (MRI). The contribution of secretion to gastric volume was assessed. Parameters that describe GE were calculated from validated models. Inter-observer agreement and reproducibility were assessed. KEY RESULTS NTM produced moderate fullness (VAS ≥30) but no more than mild dyspeptic symptoms (VAS <30) in 24 HVs. Stable binding of meal components to labels in gastric conditions was confirmed. Distinct early and late-phase GE were detected by both modalities. Liquid GE half-time was median 49 (95% CI: 36-62) min and 68 (57-71) min for GS and MRI, respectively. Differences between GS and MRI measurements were explained by the contribution of gastric secretion. Breaking strength for agar-beads was 0.8 N/m(2) such that median 25 (8-50) % intact agar-beads and 65 (47-74) % solid material remained at 120 min on MRI and GS, respectively. Good reproducibility for liquid GE parameters was present and GE was not altered by agar-beads. CONCLUSIONS & INFERENCES The NTM provided an objective assessment of gastric motor and sensory function. The results were reproducible and liquid emptying was not affected by non-nutrient agar-beads. The method is potentially suitable for clinical practice.

Abstract
BACKGROUND Obesity is considered as a risk factor for many functional gastrointestinal disorders. The aim of the study was to evaluate if functional digestive disorders are associated with specific body mass index groups and gender. METHODS A total of 1074 patients (50.3 ± 16.5 years, 67 % females) filled out a standard Rome III questionnaire (79 % acceptance rate). The patients were assigned to five groups according to their body mass index: underweight (6 %), normal (49 %), overweight (28 %), obese (12 %), and morbidly obese (5 %). Data analysis was performed using multinomial logistic regression; subjects with the normal weight were the reference group. RESULTS Patients presented specific demographic and clinical characteristics according to the weight groups. Underweight patients were younger (p < 0.001), and presented a female predominance (p = 0.006), dysphagia (p = 0.013) and soiling (p = 0.021). Overweight patients were older (p = 0.001), and reported more frequently globus (p = 0.001), regurgitation (p = 0.004), postprandial distress syndrome (p = 0.009). Obese patients reported more frequently regurgitation (p < 0.001). Morbid obese patients reported dyspepsia (p = 0.046). In patients, the odds of regurgitation increased with body mass index from underweight to obesity, but not when compared to morbid obesity. The probability of globus and regurgitation increased with body mass index and presented a steeper increase in females. CONCLUSIONS In patients with functional gastrointestinal disorders, globus and regurgitation are associated with body mass index, mainly in female patients.

Abstract
Functional gastrointestinal disorders (FGID) are common clinical syndromes diagnosed in the absence of biochemical, structural, or metabolic abnormalities. They account for significant morbidity and health care expenditures and are identifiable across variable age, geography, and culture. Etiology of abdominal pain associated FGIDs, including functional dyspepsia (FD), remains incompletely understood, but growing evidence implicates the importance of visceral hypersensitivity and electromechanical dysfunction. This manuscript explores data supporting the role of visceral hypersensitivity and electromechanical dysfunction in FD, with focus on pediatric data when available, and provides a summary of potential therapeutic targets.

Abstract
BACKGROUND The incidence and severity of gastroesophageal reflux disease (GERD) in Japan tends to increase in elderly women. Rikkunshito (RKT), a traditional Japanese medicine, acts as a prokinetic agent and improves gastric emptying and gastric accommodation. Our previous prospective randomized placebo-controlled study showed that RKT combined with a standard-dose of rabeprazole (RPZ) significantly improved the acid-related dysmotility symptoms (ARD) in elderly patients with proton pump inhibitor (PPI)-refractory non-erosive reflux disease (NERD). This study aimed to evaluate clinical characteristics of elderly PPI-refractory NERD patients with ARD symptoms who responded to RKT. METHODS Two hundred forty-two patients with PPI-refractory NERD were randomly assigned to 8 weeks of either RPZ (10 mg/q.d.) + RKT (7.5 g/t.i.d.) (RKT group) or RPZ + placebo (PL group). Among them, 95 were elderly (≥65 years) with ARD (RKT group: n = 52; PL group: n = 43). We analyzed the changes using the 12 subscale score of frequency scale for the symptoms of GERD (FSSG) and 15 items of the Gastrointestinal Symptom Rating Scale at 4 and 8 weeks and compared the therapeutic efficacy between the 2 groups. RESULTS There were no marked differences in baseline demographic or clinical characteristics in the 2 groups except for rate of current smoking. The FSSG score (mean ± SD at 0, 4, and 8 weeks) in both the RKT (16.0 ± 7.0; 9.9 ± 8.4; 7.0 ± 6.4) and PL (15.1 ± 6.4; 10.9 ± 6.7, 11.1 ± 8.5) groups significantly decreased after treatment. However, the degree of improvement of total and ARD scores of FSSG after the 8-week treatment was significantly greater in the RKT group than in the PL group. Combination therapy with RKT for 8 weeks showed significant improvement in 3 subscale scores (abdominal bloating, heavy feeling in stomach and sick feeling after meals) of the ARD domain and 1 subscale score (heartburn after meals) of the reflux symptom domain. CONCLUSIONS RKT may be useful for improving GERD symptoms in elderly PPI-refractory NERD patients with ARD. Thus, RKT was particularly effective for resolving postprandial GERD symptoms (heavy feeling in stomach, sick feeling, and heartburn after meals). TRIAL REGISTRATION (UMIN000005880).

Abstract
Dyspeptic symptoms are common with most patients suffering functional disorders that remain a therapeutic challenge for medical practitioners. Within the last three decades, gastric infection, altered motility, and hypersensitivity have gained and lost traction in explaining the development of functional dyspepsia. Considering these shifts, the aim of this review was to analyze changing understanding of and approaches to dyspepsia over a longer time period. Monographs, textbooks, and articles published during the last three centuries show that our understanding of normal gastric function has improved dramatically. With increased insight came new ideas about disease mechanisms, diagnostic options, and treatments. Despite shifts over time, the importance of functional abnormalities was recognized early on and explained in the context of societal influences and stressors, anxieties, and biological influences, thus resembling the contemporary biopsychosocial model of illness. Symptoms were often attributed to changes in secretion, motility, and sensation or perception with technological innovation often influencing proposed mechanisms and treatments. Many of the principles or even agents applied more than a century ago are still part of today's approach. This includes acid suppression, antiemetics, analgesics, and even non-pharmacologic therapies, such as gastric decompression or electrical stimulation of the stomach. This historical information does not only help us understand how we arrived at our current state of knowledge and standards of care, it also demonstrates that enthusiastic adoption of various competing explanatory models and the resulting treatments often did not survive the test of time. In view of the benign prognosis of dyspepsia, the data may function as a call for caution to avoid the potential harm of overly aggressive approaches or treatments with a high likelihood of adverse effects.

Abstract
OBJECTIVE To examine gastric function, as well as the presence of somatic complaints, anxiety symptoms, and functional gastrointestinal disorders (FGIDs), in adolescents with anorexia nervosa (AN) before and after nutritional rehabilitation. STUDY DESIGN Sixteen females with AN and 22 healthy controls with similar demographic profiles were included. Gastric emptying (measured as residual gastric volume) and gastric accommodation (measured as postprandial antral diameter) were assessed with abdominal ultrasonography. Participants completed the Children's Somatization Inventory (CSI), the Screen for Child Anxiety-Related Emotional Disorders, and the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III version. All testing was repeated 3-4 months later. RESULTS Body mass index in the AN group improved over time (P = .012). Fasting gastric parameters were similar in the 2 groups. Maximum postprandial antral diameter was significantly greater in controls compared with the AN group (P = .008). Only adolescents with AN demonstrated a significant increase in maximum postprandial diameter at repeat testing (P = .009). There was no difference in residual gastric volume between the 2 groups. Initial CSI scores were higher in adolescents with AN (P < .0001), including higher scores for nausea and abdominal pain. CSI scores were significantly lower in adolescents with AN (P = .035). Initial scores on the Screen for Child Anxiety-Related Emotional Disorders were significantly higher in adolescents with AN (P = .0005), but did not change over time. Adolescents with AN met significantly more criteria for FGIDs (P = .003). CONCLUSION Adolescents with AN have impaired gastric accommodation that improves after nutritional rehabilitation, have significantly more somatic complaints, and meet more criteria for anxiety disorders and FGIDs. After nutritional rehabilitation, somatization improves and FGIDs become less common, but symptoms of anxiety persist.

Abstract
OBJECTIVE To present our experience using cyproheptadine, a potent serotonin antagonist used to stimulate appetite, to treat dyspeptic symptoms in children. STUDY DESIGN This was a retrospective open-label study conducted to evaluate the safety and efficacy of cyproheptadine in children with refractory upper gastrointestinal symptoms (eg, nausea, early satiety, vomiting, retching after fundoplication, abdominal pain). Response was graded as resolution if symptoms resolved and medication was discontinued, as significant improvement if symptoms resolved with no further interventions, and as failure with any other outcome. RESULTS A total of 80 children (65% females) aged <12 years (mean age, 10 years) were included. Response to therapy was reported in 55% of patients. Multivariate analysis revealed better response in children and females (P = .04 and .03, respectively). No associations were found between response to therapy response and gastric emptying, antroduodenal manometry, functional dyspepsia, vomiting, and use of cyproheptadine as first therapy. Early vomiting (occurring within 1 hour after starting a meal) responded better than late vomiting (P = .03), and patients with retching after undergoing Nissen fundoplication had an 86% response rate. Twenty-four patients (30%) complained of side effects, all mild, including somnolence (16%), irritability and behavioral changes (6%), increased appetite and weight gain (5%), and abdominal pain (2.5%), but only 2 of these patients discontinued therapy. Multivariate analysis demonstrated an association between side effects and lack of response to therapy (P = .04), but no associations with age and sex. CONCLUSION Cyproheptadine is safe and effective for treating dyspeptic symptoms in children, particularly in young children and those with early vomiting and retching after fundoplication.

Abstract
BACKGROUND Factors associated with abdominal pain in gastroparesis are incompletely evaluated and comparisons of pain vs other symptoms are limited. This study related pain to clinical factors in gastroparesis and contrasted pain/discomfort- with nausea/vomiting-predominant disease. METHODS Clinical and scintigraphy data were compared in 393 patients from seven centers of the NIDDK Gastroparesis Clinical Research Consortium with moderate-severe (Patient Assessment of Upper Gastrointestinal Disorders Symptoms [PAGI-SYM] score ≥ 3) vs none-mild (PAGI-SYM < 3) upper abdominal pain and predominant pain/discomfort vs nausea/vomiting. KEY RESULTS Upper abdominal pain was moderate-severe in 261 (66%). Pain/discomfort was predominant in 81 (21%); nausea/vomiting was predominant in 172 (44%). Moderate-severe pain was more prevalent with idiopathic gastroparesis and with lack of infectious prodrome (P ≤ 0.05) and correlated with scores for nausea/vomiting, bloating, lower abdominal pain/discomfort, bowel disturbances, and opiate and antiemetic use (P < 0.05), but not gastric emptying or diabetic neuropathy or control. Gastroparesis severity, quality of life, and depression and anxiety were worse with moderate-severe pain (P ≤ 0.008). Factors associated with moderate-severe pain were similar in diabetic and idiopathic gastroparesis. Compared to predominant nausea/vomiting, predominant pain/discomfort was associated with impaired quality of life, greater opiate, and less antiemetic use (P < 0.01), but similar severity and gastric retention. CONCLUSIONS & INFERENCES Moderate-severe abdominal pain is prevalent in gastroparesis, impairs quality of life, and is associated with idiopathic etiology, lack of infectious prodrome, and opiate use. Pain is predominant in one fifth of gastroparetics. Predominant pain has at least as great an impact on disease severity and quality of life as predominant nausea/vomiting.

Abstract
GERD and functional dyspepsia are the two most prevalent upper gastrointestinal disorders. Gastro-oesophageal reflux is most commonly diagnosed using the cardinal symptoms of heartburn and regurgitation. Patients might also be diagnosed using a questionnaire, after empiric treatment with an acid suppressant, after upper endoscopy or by pH testing. Functional dyspepsia is best diagnosed using symptoms outlined by the Rome committee in conjunction with a normal upper endoscopy. Theoretically, distinguishing these two populations should be easy for all health-care providers. In reality, however, carefully separating out these two populations can be quite difficult, as substantial overlap exists epidemiologically, symptomatically and even diagnostically. This overlap renders precise diagnosis a challenge; given the limited treatment options, the primary goal is to identify those patients who will respond to acid suppressive therapy. Despite the frequency with which functional dyspepsia and GERD overlap, remarkably few studies have investigated this overlap. Most recommendations are based on data derived from separate studies of functional dyspepsia and GERD. A further limitation of existing studies is their failure to differentiate between the various diagnostic categories into which the individual presenting with heartburn might belong.

Abstract
Functional dyspepsia refers to painful and nonpainful symptoms that are perceived to arise in the upper digestive tract but are not secondary to organic, systemic or metabolic diseases. The symptoms of this syndrome often overlap with those of GERD and IBS, making its management far from simple. If Helicobacter pylori infection is diagnosed in patients with functional dyspepsia, it should be treated. In patients with mild or intermittent symptoms, reassurance and lifestyle advice might be sufficient; in patients not responding to these measures, or in those with more severe symptoms, drug therapy should be considered. Both PPIs and prokinetics can be used in initial empirical pharmacotherapy based on symptom patterns--a PPI is more likely to be effective in the presence of retrosternal or epigastric burning or epigastric pain, whereas a prokinetic is more effective in dyspepsia with early satiation or postprandial fullness. Although combinations of PPIs and prokinetics might have additive symptomatic effects, single-drug therapy is initially preferable. Antidepressants or referral to a psychiatrist or psychotherapist can be considered in nonresponders and in those whose symptoms have a marked effect on daily functioning. Despite extensive research, functional dyspepsia treatment often remains unsatisfactory. Better characterization of dyspeptic subgroups and understanding of underlying mechanisms will enable treatment advances to be made in the future.

Gastric hypochlorhydria is associated with an exacerbation of dyspeptic symptoms in female patients. J Gastroenterol 2013; 48:214-21.

Abstract
BACKGROUND Gender and gastric acid have been suggested to be independently involved in the pathophysiology of functional dyspepsia, but the interrelationship among gender, dyspeptic symptoms, and gastric acid secretion remains to be evaluated. We sought to explore this issue in dyspeptic patients. METHODS A total of 89 outpatients (male, 36; mean age, 55.6 years) with dyspeptic symptoms were analyzed. The degree of dyspeptic symptoms was evaluated and scored using a symptom questionnaire consisting of 3 subcategories: dysmotility-related symptoms, reflux-related symptoms, and epigastric pain-related symptoms. Stimulated gastric acid secretion was directly measured using an endoscopic gastrin test. RESULTS The total symptom scores and the epigastric pain-related symptom scores were significantly higher in female patients than in male patients. The dysmotility-related and reflux-related symptom scores were also higher, but not significantly, in the female patients. Multiple regression analysis of age, gender, habitual drinking, smoking, Helicobacter pylori infection, and gastric acid secretion revealed that gender and gastric hypochlorhydria, defined as less than 2.1 mEq/10 min in the endoscopic gastrin test, were significantly associated with higher dyspeptic symptom scores. The total scores and the dysmotility-related scores were significantly higher in the patients with gastric hypochlorhydria than in those with gastric non-hypochlorhydria, and this difference was found to be present only in females. CONCLUSIONS Gastric hypochlorhydria in female dyspeptic patients may be involved in the exacerbation of dyspeptic symptoms. Differences in the responsiveness to gastric hypochlorhydria between males and females may be partly responsible for the gender differences in the prevalence and severity of dyspeptic symptoms.

Abstract
AIM: To investigate the prevalence of impaired proximal stomach function and its relationship to symptoms in patients with functional dyspepsia (FD).
METHODS: Fifty-nine patients with FD and 32 healthy subjects (HS) were enrolled in this study. After an overnight fast of at least 12 h, a double-lumen polyvinyl tube with an adherent plastic bag that was finely folded was introduced through the patient's mouth. A gastric barostat was used to evaluate proximal stomach function (sensitivity, accommodation and compliance). After an overnight fast, gastric emptying was measured by single photon emission computerized tomography (SPECT). The gastric emptying curve was plotted to calculate the gastric emptying half-time. Individual dyspepsia symptom scores were obtained for all patients and their relationship with proximal stomach function was assessed. Logistic regression analysis and χ2 statistics were used to identify the association between proximal stomach function and symptoms.
RESULTS: Visceral hypersensitivity to gastric distention was found in 44.07% of the patients, and their gastric emptying half-time did not significantly differ from that of patients with normal sensitivity. Epigastric pain was significantly more prevalent in patients with visceral hypersensitivity than in those with normal sensitivity (P < 0.01). Epigastric pain was independently and significantly associated with hypersensitivity to gastric distention (OR = 4.430, P < 0.05). Impaired gastric accommodation was found in 37.29% of the patients, and their gastric emptying half-time did not differ from that of other patients. Impaired gastric accommodation to gastric distention was associated with a higher prevalence of early satiety (P < 0.05). The presence of early satiety was the only symptom that was independently associated with impaired accommodation to gastric distention (OR = 3.231, P < 0.05). Reduced compliance was found in 54.24% of the patients; however, no relationship was found between reduced compliance and dyspeptic symptoms.
CONCLUSION: Symptoms are associated with impaired proximal stomach function in patients with FD. Epigastric pain and early satiety can be used to predict the presence of hypersensitivity and impaired accommodation, respectively.

Abstract
INTRODUCTION Recommendations for gastric emptying scintigraphy (GES) suggest imaging over 4 hours to better define gastroparesis. AIMS To determine the value of defining delayed gastric emptying at time points earlier than 4 hours. METHODS GES was performed with ingestion of a liquid egg white meal with imaging at 0, 0.5, 1, 2, 3, and 4 hours. Patients completed the Patient Assessment of Gastrointestinal Symptoms questionnaire immediately before GES. RESULTS Of 1499 patients undergoing GES from September 2007 to January 2010 (76.2% were female, mean age of 45.5±0.5 y, 21.3% had diabetes, 9.5% had earlier gastric surgery), 160 (10.7%) had increased gastric retention at 1 hour (>90%), 404 (27%) had increased retention at 2 hours (>60%), 576 (38.4%) had increased retention at 3 hours (>30%), and 629 (42%) had increased retention at 4 hours (>10%). Gastric retention at 4 hours correlated with retention at 3 hours (r=0.890; P<0.001), 2 hours (r=0.738; P<0.001), and 1 hour (r=0.510; P<0.001). Symptoms correlated better with the gastric retention at later time points. The symptoms correlating with gastric retention at 4 hours included early satiety (r=0.170; P<0.01), vomiting (r=0.143; P<0.01), feeling excessively full after meals (r=0.123; P<0.01), and loss of appetite (r=0.122; P<0.01). CONCLUSIONS Gastric retention at 4 hours correlates well with gastric retention at 3 hours, good at 2 hours, but only fair with gastric retention at 1 hour. Gastric retention at 1 hour may miss 36% of patients found to have delayed gastric emptying at 4 hours. Symptoms (early satiety, vomiting, feeling excessively full after meals, and loss of appetite) correlated better with the gastric retention at later time points.

Abstract
Patients with gastroparesis often present a challenge to the treating physician. Postprandial symptoms with nausea and vomiting may not only lead to nutritional and metabolic consequences, but also cause significant disruptions to social activities that often center around food. While the definition of gastroparesis focuses on impaired gastric emptying, treatment options that affect gastric function are limited and often disappointing. The female predominance, the mostly idiopathic nature of the illness with a common history of abuse, and coexisting anxiety or depression show parallels with other functional disorders of the gastrointestinal tract. These parallels provided the rationale for some initial studies investigating alternative therapies that target the brain rather than the stomach. This emerging shift in medical therapy comes at a time when clinical studies suggest that gastric electrical stimulation may exert its effects by modulating visceral sensory processing rather than altering gastric motility. Physiologic and detailed anatomic investigations also support a more complex picture with different disease mechanisms, ranging from impaired accommodation to apparent visceral hypersensitivity or decreased interstitial cells of Cajal to inflammatory infiltration of myenteric ganglia. Delayed gastric emptying remains the endophenotype defining gastroparesis. However, our treatment options go beyond prokinetics and may allow us to improve the quality of life of affected individuals.

Abstract
BACKGROUND & AIMS Idiopathic gastroparesis (IG) is a common but poorly understood condition with significant morbidity. We studied characteristics of patients with IG enrolled in the National Institute of Diabetes and Digestive and Kidney Diseases Gastroparesis Clinical Research Consortium Registry. METHODS Data from medical histories, symptom questionnaires, and 4-hour gastric emptying scintigraphy studies were obtained from patients with IG. RESULTS The mean age of 243 patients with IG studied was 41 years; 88% were female, 46% were overweight, 50% had acute onset of symptoms, and 19% reported an initial infectious prodrome. Severe delay in gastric emptying (>35% retention at 4 hours) was present in 28% of patients. Predominant presenting symptoms were nausea (34%), vomiting (19%), an abdominal pain (23%). Women had more severe nausea, satiety, constipation, and overall gastroparesis symptoms. Patients who experienced acute-onset IG had worse nausea than those with insidious onset. Overweight patients had more bloating and gastric retention at 2 hours but less severe loss of appetite. Patients with severely delayed gastric emptying had worse vomiting and more severe loss of appetite and overall gastroparesis symptoms. Severe anxiety and depression were present in 36% and 18%, respectively. A total of 86% met criteria for functional dyspepsia, primarily postprandial distress syndrome. CONCLUSIONS IG is a disorder that primarily affects young women, beginning acutely in 50% of cases; unexpectedly, many patients are overweight. Severe delay in gastric emptying was associated with more severe symptoms of vomiting and loss of appetite. IG is a diverse syndrome that varies by sex, body mass, symptom onset, and delay in gastric emptying.

Abstract
PURPOSE OF REVIEW Abnormalities of gastroduodenal motility are considered key players in the pathogenesis of upper gastrointestinal symptoms in disorders such as functional dyspepsia and gastroparesis. Abnormalities of sensory control are considered another important factor that contributes to symptom generation. This review summarizes recent progress in our understanding of gastroduodenal motility and sensitivity in health and in disease. RECENT FINDINGS Although gastric and small intestinal motility remain an important focus of research, including the application of the SmartPill (SmartPill Corp., Buffalo, New York, USA) wireless motility monitoring capsule, duodenal sensitivity and low-grade duodenal inflammation are new areas of interest in the pathogenesis of functional dyspepsia. A number of genetic polymorphisms associated with functional dyspepsia are being investigated, but large-scale studies are still lacking. Central processing of visceral stimuli, and its role in the pathogenesis of functional dyspepsia, is another important emerging topic. Therapeutic studies have reported on novel pharmacological approaches in functional dyspepsia and gastroparesis, as well as gastric electrical stimulation in the treatment of refractory gastroparesis. SUMMARY There is gradual progress in our understanding of the pathogenesis of gastroduodenal symptoms. Areas of recent advances including the recognition of low-grade duodenal inflammation, the role of central nervous system processing in visceral hypersensitivity and the exploration of novel pharmacotherapeutic approaches.

Abstract
BACKGROUND Gastroparesis, a chronic disorder of abnormal gastric motility, is common in patients with diabetes mellitus. A synthetic, selective ghrelin receptor agonist, TZP-101, is in clinical development for treatment of gastroparesis. This double-blind, randomized, placebo-controlled study evaluated the safety and efficacy of multiple TZP-101 doses in patients with moderate to severe symptomatic diabetic gastroparesis. METHODS Patients were admitted to the hospital and adaptively randomized to receive a single 30-min intravenous infusion of 20, 40, 80, 160, 320, or 600 μg kg(-1) TZP-101, (n = 57) or placebo, (n = 19) for four consecutive days. Symptoms were evaluated daily with the patient-rated Gastroparesis Cardinal Symptom Index (GCSI) and Gastroparesis Symptom Assessment (GSA). Clinicians rated gastroparesis symptoms on treatment day 4. KEY RESULTS The 80 μg kg(-1) dose was identified as the most effective dose. On day 4, there was statistically significant improvement compared with placebo in the severity of GCSI Loss of Appetite and Vomiting scores for that dose group (P = 0.034 and P = 0.006). In addition, at the 80 μg kg(-1) dose, the proportion of patients with at least 50% improvement in vomiting score was significantly different (P = 0.019) compared with placebo. Meal-related GSA scores for Postprandial fullness were significantly improved in the 80 μg kg(-1) TZP-101 group compared with placebo (P = 0.012). Clinicians rated the 80 μg kg(-1) group better improved than placebo for overall symptom assessment (P = 0.047). Safety profiles were similar in the placebo and TZP-101 groups and all doses were well-tolerated. CONCLUSIONS & INFERENCES TZP-101 appears to be safe, well-tolerated, and effective at acutely addressing several gastroparesis symptoms.

Abstract
BACKGROUND & AIMS Although the most commonly recognized symptoms of gastroparesis (GP) are nausea and vomiting, patients also report abdominal pain. We aimed to define the prevalence, severity, and quality of abdominal pain in GP and to correlate abdominal pain with gastric emptying (GE) and quality of life. METHODS Patients presumed to have GP underwent 4-hour GE scintigraphy and upper endoscopy examinations and completed the following: patient assessments of gastrointestinal symptoms (Patient Assessment of Upper Gastrointestinal Symptom Severity Index), abdominal pain questionnaires (Short-Form of the McGill Pain Questionnaire), and quality-of-life questionnaires. RESULTS The study group consisted of 68 patients (58 female; 10 male) with delayed GE (18 diabetic gastroparesis [DG] and 50 idiopathic gastroparesis [IG]). Abdominal pain was present in 90% of patients (89% DG, 90% IG) and nausea was present in 96% (100% DG, 94% IG). Abdominal pain was epigastric in 43% and umbilical in 13%. Pain occurred daily in 43% and was constant in 38%. Pain often was induced by eating (72%), was nocturnal (74%), and interfered with sleep (66%). Severity ranking of symptoms based on the Patient Assessment of Upper Gastrointestinal Symptom Severity Index was as follows: abdominal fullness (3.8 +/- 0.2), bloating (3.6 +/- 0.2), nausea (3.6 +/- 0.2), upper abdominal discomfort (3.3 +/- 0.2), upper abdominal pain (3.0 +/- 0.2), and vomiting (2.2 +/- 0.2). Abdominal pain severity did not correlate with GE, but had moderate correlation with quality of life. CONCLUSIONS Abdominal pain is a frequent symptom in patients with GP, comparable with nausea and vomiting. Abdominal pain correlates with impaired quality of life but not with GE.

Abstract
BACKGROUND Symptoms of gastroparesis based on patient recall correlate poorly with gastric emptying. The aim of this study is to determine if symptoms recorded during gastric emptying scintigraphy (GES) correlate with gastric emptying and with symptoms based on patient recall. METHODS Patients undergoing GES completed the Patient Assessment of GI Symptoms (PAGI-SYM) assessing symptoms over the prior 2 weeks and a questionnaire for which patients graded six symptoms during GES. A Symptom Severity Index (SSI) represented the mean of six symptoms at each time point. KEY RESULTS A total of 560 patients underwent GES for clinical evaluation of symptoms. Of 388 patients included in the study: 232 patients had normal GES (NGES), 156 delayed GES (DGES), and 11 rapid GES (RGES). Symptom severity index increased pre to postprandial for each group: NGES: 0.51 +/- 0.07 to 0.92 +/- 0.03, DGES: 0.60 +/- 0.09 to 1.13 +/- 0.05, and RGES: 0.56 +/- 0.12 to 0.79 +/- 0.13. Delayed gastric emptying scintigraphy patients had a higher postprandial SSI than NGES patients (1.13 +/- 0.05 vs 0.92 +/- 0.03, P < 0.05). Postprandial symptoms of stomach fullness (1.9 +/- 0.12 vs 1.5 +/- 0.09; P = 0.011), bloating (1.4 +/- 0.11 vs 1.1 +/- 0.09; P = 0.033), and abdominal pain (1.1 +/- 0.08 vs 0.7 +/- 0.12; P = 0.012) were higher in DGES than NGES. Symptom severity based on PAGI-SYM for 2 weeks prior to GES correlated with symptoms during the test for nausea (NGES, r = 0.61; DGES, r = 0.70), stomach fullness (NGES, r = 0.47; DGES, r = 0.60), and bloating (NGES, r = 0.62, DGES, r = 0.66). CONCLUSIONS & INFERENCES Stomach fullness, bloating, and abdominal pain recorded during GES were higher in patients with delayed gastric emptying than in patients with normal gastric emptying. Symptoms recorded during GES correlated with those during daily life by patient recall.

Abstract
Dyspepsia is a common term used for a heterogeneous group of abdominal symptoms. Functional dyspepsia (FD) is the focus of this review. The 2006 Rome III criteria defined FD and its subgroups, postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS). FD is a very common condition with a high prevalence throughout the world, adversely affecting the quality of life of patients. The pathophysiology of FD has been under investigation during the past two decades. Multiple mechanisms such as abnormal gastric emptying, visceral hypersensitivity, impaired gastric accommodation, and central nervous system factors are likely involved. Several tests are available for the assessment of various physiologic functions possibly involved in the pathogenesis of FD, and some of these could be used in clinical practice, helping to understand the abnormalities underlining patients' complaints. Currently, the possibilities of pharmacological therapy for FD are still limited, however, experience of using prokinetics, tricyclic antidepressants, selective serotonin-reuptake inhibitors (SSRIs), proton-pump inhibitors (PPIs), and several alternative techniques has been accumulated. The different combinations of alterations in physiologic gastrointestinal and central nervous system functions result in the very heterogeneous nature of FD so combined approaches to these patients could be beneficial in challenging cases.
