Abstract
BACKGROUND There is some degree of overlap in the symptomatic spectrum of patients with gastroparesis and small intestinal bacterial overgrowth (SIBO) and some of the etiologies for gastroparesis, such as diabetes mellitus and vagotomy are known to predispose to SIBO. The aims of our study were to measure the prevalence of SIBO in a cohort of gastroparetic patients with prominence of abdominal pain and bloating and try to identify predictors with regard to demographics, concurrent use of medications such as prokinetics, proton pump inhibitors, and opiate analgesics, and predominant bowel movement abnormality. METHODS Glucose breath testing (GBT) for SIBO was performed in 50 patients (41 females) with gastroparesis. Demographic data, medication profiles, baseline and peak measurements of hydrogen or methane gas on the GBT, and results of the most recent gastric emptying scintigraphy test were recorded. RESULTS Thirty of fifty (60%) patients had a positive GBT for SIBO on the basis of hydrogen (63%), methane (27%), or both criteria (10%). SIBO was more likely (P=0.001) in patients with gastroparetic symptoms of greater duration (mean 5 y; 95% CI: 4-6 y). No significant differences were noted in both groups with regard to age, sex, or etiology of gastroparesis. Gastric emptying was similar in the SIBO and non-SIBO group (P>0.05). After adjusting for tegaserod and opiate analgesic use, 14/23 (61%) had a positive GBT. CONCLUSIONS SIBO is very common in gastroparetics with predominance of abdominal pain and bloating, especially those with a longer duration of gastroparesis. Awareness of SIBO in the setting of gastroparesis will facilitate separation of the 2 entities and allow appropriate therapies to be instituted.

Abstract
BACKGROUND The clinical course of patients with gastroparesis is characterized by symptomatic exacerbations often necessitating hospitalization. AIMS To investigate precipitating factors leading to hospitalization for exacerbation of symptoms in patients with gastroparesis. METHODS This was a retrospective review of 103 admissions (63 patients) for gastroparesis exacerbation. RESULTS Etiologic categories for gastroparetic patients were diabetic (43%), idiopathic (39%), and post surgical (8%). Poor glycemic control was present in 36%, infection in 19% (12 urinary tract infections and two bacteremia), and noncompliance with or intolerance of, medications in six and 5% of patients, respectively. Fasting morning cortisol concentrations were \3 mcg/dl in 9%. Elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were seen in 34 of 65 (52%) and 11 of 50 patients (22%), respectively. No identifiable infection was found in 74 and 45% of patients with elevated ESR and elevated CRP, respectively. ESR and CRP were higher when patients were symptomatic necessitating hospitalization (26.2 +/- 6.6 mm/h and 1.6 +/- 1.0 mg/l) compared with when they were seen in outpatient follow-up and less symptomatic (10.3 +/- 2.9 mm/h and 0.3 +/- 0.1 mg/l; P = 0.0001 and P = 0.211, respectively). CONCLUSIONS Poor glycemic control, infection, noncompliance with/intolerance of medications, and, perhaps, adrenal insufficiency were contributory factors leading to hospitalizations of gastroparetic patients. Hospitalized patients with gastroparesis exacerbations had elevated ESR and CRP levels. Although many patients with elevated inflammatory markers had evidence of infection, some did not. Assessment of inflammatory markers may help indicate those gastroparetic patients in whom a search for infection should be undertaken.

Abstract
It is long known that both type 1 and type 2 diabetes can be associated with changes in gastric emptying; a number of publications have linked diabetes to delayed gastric emptying of variable severity and often with poor relationship to gastrointestinal symptomatology. In contrast, more recent studies have reported accelerated gastric emptying when adjusted for glucose concentration in patients with diabetes, indicating a reciprocal relationship between gastric emptying and ambient glucose concentrations. This review proposes that gastroparesis or gastroparesis diabeticorum, a severe condition characterized by a significant impairment of gastric emptying accompanied by severe nausea, vomiting, and malnutrition, is often overdiagnosed and not well contrasted with delays in gastric emptying. The article offers a clinically relevant definition of gastroparesis that should help differentiate this rare condition from (often asymptomatic) delays in gastric emptying. The fact that delayed gastric emptying can also be observed in non-diabetic individuals under experimental conditions in which hyperglycaemia is artificially induced suggests that a delay in gastric emptying rate when blood glucose concentrations are high is actually an appropriate physiological response to hyperglycaemia, slowing further increases in blood glucose. The article discusses the strengths and weaknesses of various methodologies for assessing gastric emptying, especially with respect to the diabetes population, and reviews newer diabetes therapies that decelerate the rate of gastric emptying. These therapies may be a beneficial tool in managing postprandial hyperglycaemia because they attenuate rapid surges in glucose concentrations by slowing the delivery of meal-derived glucose.

Abstract
We report a case of paediatric Boerhaave's syndrome in 15-year-old girl associated with massive dilatation of the stomach into the pelvis and transient hepatitis of uncertain aetiology. This cluster of clinical finding has not previously been reported. The young girl initially presented with abdominal pain, vomiting and lower urinary tract symptoms. She was initially treated for urinary tract infection after urine dipstick showed leucocytes and nitrates. Later she was found to have the spectrum of findings as described. Patient was treated by restricting to strict no oral intake and gastric decompression. Enteral nutrition maintained via a feeding jejunostomy.Boerhaave's syndrome frequently presents in the context of other emetogenic illnesses which may mimic its features as a result the diagnosis can be difficult. A high index of clinical suspicion is therefore required. We review the literature of paediatric Boerhaave's syndrome to aid the clinician with this diagnostic conundrum.

Abstract
BACKGROUND & AIMS The aim of this study was to evaluate the prognostic value of gastric emptying studies on the morbidity associated with diabetic gastroparesis. METHODS This was a parallel cohort study of 3 groups. Group A (n = 94) contained diabetic patients (type 1 and type 2) with classic symptoms of gastroparesis (including early satiety, postprandial fullness, bloating, abdominal swelling, nausea, vomiting, and retching) and delay in radionucleotide gastric emptying study. Group B (n = 94) contained diabetic subjects with classic symptoms of gastroparesis but negative scintigraphy. Group C (n = 94) contained diabetic subjects without symptoms of gastroparesis. Data were gathered on the number of days hospitalized and hospitalizations, office visits, emergency department visits, death rate, glycosylated hemoglobin levels, medications, and past medical history. RESULTS Group A had significantly more hospital days per 1000 patient days (25.5) than both group B (5.1; P < .01) and group C (2.3; P < .01). Group A also had significantly more hospitalizations, office visits, and emergency department visits than both group B and group C. Deaths and mean glycosylated hemoglobin levels did not differ between the groups. Patients in group A were more likely to have cardiovascular disease (19.2% vs 6.4%, A vs C; P < .05), hypertension (63% vs 43%, A vs C; P = .005), and retinopathy (33% vs 11.7%, A vs C; P < .001). CONCLUSIONS A delayed radionucleotide gastric emptying study predicts negative health outcomes in diabetic patients with symptoms of gastroparesis. We identified a correlation between diabetic gastroparesis and cardiovascular disease, hypertension, and retinopathy that may indicate an underlying vascular etiology.

Abstract
OBJECTIVES To evaluate the efficacy of botulinum toxin-A in the treatment of postvagotomy gastroparesis. METHODS This open-labeled trial identified and recruited 11 subjects who developed symptomatic gastroparesis after a vagotomy (9 fundoplication, 1 trauma, and 1 exploratory laparotomy). Gastroparesis was defined as an abnormal solid-phase gastric emptying test using the standardized 4-hour radionuclide eggbeater meal method and vagotomy was confirmed with a sham meal challenge test. To complete the study, subjects should have completed the 6-month follow-up visit after their pylorus was injected with botulinum toxin-A injection in a 4-quadrant manner. Patients either received 100 (n = 2) or 200 (n = 9) units of botulinum toxin. Questionnaires recorded symptom severity of gastroparesis at baseline and at monthly intervals for 6 months after the therapy was completed by the patients. RESULTS Of the 11 subjects initially recruited, 10 finished the 6-month follow-up visit (7 women). Mean age was 51 years (range, 31-84 years). Mean symptom score at baseline was 16 (95% CI 13-19) and showed a numerical decline to 9 (P > 0.05) over the 6-month period after the procedure (95% CI 5-13). Seven (70%) patients observed >30% improvement in the total symptom score. No complications were recorded. CONCLUSIONS In conclusion, this open-label study in patients with postvagotomy gastroparesis patients reveals a reduction of gastroparetic symptoms at 1 and 3 months after treatment with pyloric injection of botulinum toxin-A, with return of symptoms by 6 months. Thus, botulinum toxin treatment does not produce a sustained reduction in gastroparetic symptoms in this clinical setting.

Abstract
BACKGROUND AND OBJECTIVES Gastric emptying (GE) may be delayed or rapid in diabetes mellitus. We sought to ascertain differences in risk factors or associated features (i.e. diabetic 'phenotype') among patients with diabetes who have rapid, slow or normal GE. METHODS From a database of patients in whom gastrointestinal transit was assessed by scintigraphy, we compared the diabetic phenotype in diabetic patients with rapid, slow and normal GE. RESULTS Of 129 patients, 55 (42%) had normal, 46 (36%) had delayed and 28 (22%) patients had rapid GE. In each GE category, there was an approximately equal number of type 1 and type 2 diabetes. In multivariable analyses, significant weight loss (OR, 2.81; 95% CI, 1.09-7.23) and neuropathy (OR, 3.60; 95% CI, 1.007-12.89) were the risk factors for delayed and rapid GE, respectively. Insulin therapy (OR, 0.08; 95% CI, 0.01-0.53) was associated with a lower risk of rapid compared to normal GE. However, other manifestations or characteristics of the diabetes 'phenotype' (i.e. type and duration of diabetes, glycosylated haemoglobin levels, and extraintestinal complications) were not useful for discriminating normal from delayed or rapid GE. At a specificity of 60%, clinical features were 73% sensitive for discriminating between normal and delayed GE and 80% sensitive for discriminating normal from rapid GE. CONCLUSIONS Diabetes is associated with slow and rapid GE. Because the diabetic phenotype is of limited utility for identifying disordered GE, GE should be assessed in patients with diabetes and gastrointestinal symptoms.

Abstract
Gastroparesis is a relatively common and often disabling condition that is characterized by a broad range of clinical presentation ranging from dyspeptic symptoms to nausea, vomiting, abdominal pain, malnutrition, frequent hospitalizations and incapacitation. The treatment of gastroparetic symptoms can be challenging to the gastroenterologist and the intensity of therapy varies with the physician's knowledge. Hence the determination that a patient is refractory to 'standard medical therapy' is an assessment that is subspeciality-based and could differ around the world depending on medications available. In this article, we review the use of available prokinetics, antiemetic agents, the approach for analgesia in the context of gastroparesis, and also discuss potential and evolving pharmacotherapies. The progress has been relatively limited as far as availability of new medications for gastroparesis is concerned; however, active research in developing newer prokinetics holds great promise for the future of management of this challenging entity.

Abstract
1. This study examined interactions via common metabolism or via common pharmacodynamic pathways between frequently co-prescribed metoclopramide (a prokinetic) and morphine (an opioid analgesic). 2. In human liver microsomes, morphine 3-glucuronide and morphine 6-glucuronide formation had V(max) estimates of 6.2 +/- 0.07 and 0.75 +/- 0.01 (nmole min(-1) mg(-1) protein) and K(m) estimates of 1080 +/- 37 and 665 +/- 55 (microM), respectively. The in vitro K(i) for morphine 3-glucuronide formation in the presence of metoclopramide in human liver microsomes or recombinant uridine diphosphoglucuronosyltransferase 2B7 predicted a lack of in vivo interaction. 3. Morphine (2 mg kg(-1) subcutaneously) delayed gastrointestinal meal transit in mice, metoclopramide (10 mg kg(-1) subcutaneously) had no effect on meal transit, and metoclopramide did not alter this effect of morphine. 4. Morphine (2 or 5 mg kg(-1) subcutaneously) was antinociceptive in mice (hot plate test) and metoclopramide (10 mg kg(-1) subcutaneously) did not alter the antinociceptive effects of morphine. 5. Together, the data suggest a lack of interaction between morphine and metoclopramide.

Abstract
Gastroparesis refers to abnormal gastric motility characterized by delayed gastric emptying in the absence of mechanical obstruction. The most common etiologies include diabetes, post-surgical and idiopathic. The most common symptoms are nausea, vomiting and epigastric pain. Gastroparesis is estimated to affect 4% of the population and symptomatology may range from little effect on daily activity to severe disability and frequent hospitalizations. The gold standard of diagnosis is solid meal gastric scintigraphy. Treatment is multimodal and includes dietary modification, prokinetic and anti-emetic medications, and surgical interventions. New advances in drug therapy, and gastric electrical stimulation techniques have been introduced and might provide new hope to patients with refractory gastroparesis. In this comprehensive review, we discuss gastroparesis with emphasis on the latest developments; from the perspective of the practicing clinician.

Abstract
Critical illness affects gastrointestinal motility - not only as a primary problem, which brings the patient to the intensive care unit (ICU), but also as a complication consecutive to the ICU stay. Motility disturbances may result from impaired function of gastrointestinal muscle, pacemaker cell function and nerve activity. The most important neural control system is the enteric nervous system that contains the largest collection of neurons (10(8) cells) outside the central nervous system. Through its organization it can operate independently of the brain and generate motility patterns according to need: a postprandial motility pattern starting after food intake, and an interdigestive motility pattern starting several hours after a meal. Undisturbed intestinal motility depends critically on a balanced interaction between inhibition and excitation, and a disturbance in this balance leads to severe derangements of intestinal motility. These motility disturbances differ in clinical appearance and location but can affect all parts of the gastrointestinal tract. This review focuses on select motility disturbances such as gastroparesis, postoperative ileus, and Ogilvie's syndrome. Generally effective methods to treat these conditions are given. Finally, we focus on special management options to prevent such motility disturbances or to reduce their severity.

Abstract
Phytobezoars associated with diabetic gastroparesis are often sources of diminished quality of life for patients. Poor blood sugar control has been associated with increasing gastroparesis. For recipients of pancreas transplants to correct diabetes, phytobezoar treatment post-transplant can typically be limited to invasive procedures and prokinetic agents. We present the case of an alternative treatment to phytobezoar, cola libation, i.e., "cola-lysis."

Abstract
Gastroparesis is a disorder of gastric emptying that occurs in the absence of mechanical obstruction. Its cardinal features include nausea, vomiting, bloating, early satiety and discomfort. Weight loss, dehydration, electrolyte disturbances and malnutrition may develop in severe cases. The majority of cases is idiopathic, long standing diabetes mellitus is responsible for about 25-30% of cases. Diabetic gastroparesis may render glucose control extremely difficult, its treatment represents a major challenge. Besides frequent, small meals and psychological support, several drug options are available, however, their efficacy is limited and only a few randomized studies have been performed to date. Prokinetic agents (erythromycin, domperidone, metoclopramide) and antiemetics (phenothiazines, serotonin antagonists, butyrophenones) are the most wide-spread medicaments. Among the novel, recently developed agents, 5-HT4 serotonin receptor agonists and dopamine D2 receptor antagonists are the most promising. Injection of botulinum toxin into the pyloric sphincter resulted in faster gastric emptying and symptom alleviation in some studies. Gastric electric stimulation appears to be one of the most effective options, both low and high-frequency stimulation may alleviate symptoms. Gastrostomy/jejunostomy and other surgical interventions are considered as "last resort".

Abstract
PURPOSE Gastric electrical stimulation (GES) has been performed in adults as a treatment of refractory nausea and vomiting in patients who have failed medical treatment, but has not been used in children. METHODS Nine patients with chronic nausea and vomiting with a mean age of 14 years were evaluated for temporary GES. All 9 patients subsequently underwent placement of a temporary followed by permanent GES device. Symptoms were recorded at baseline, after temporary GES, and then after permanent GES using a Likert scale for gastroparesis. Statistical analysis was performed using a paired Student's t test. RESULTS At baseline, all patients were symptomatic and most had delayed solid gastric emptying. As a group, there was a significant improvement in combined symptoms score (P = .04), nausea (P = .039), and vomiting (P = .0016). Gastric emptying and electrogastrogram values did not change significantly. Follow-up ranged from 8 to 42 months, with 7 of the 9 patients reporting sustained improvement in symptoms and improved quality of life. CONCLUSIONS Gastric electrical stimulation can be successfully applied to adolescents with intractable nausea and gastroparesis symptoms who fail medical therapy. There is a significant improvement in symptoms over a prolonged period, and there are no adverse effects of the GES. Long-term efficacy of this therapy in children needs to be established.

Abstract
BACKGROUND A major barrier to furthering our understanding of the pathophysiology of neuromuscular GI diseases, including functional GI disorders, is the inability to obtain deep gastric-wall biopsy specimens that include both layers of the muscularis propria, which allows evaluation of specific cell types, including myenteric ganglia. OBJECTIVES The aims of this preclinical study were to (1) evaluate different endoscopic approaches for obtaining deep gastric-muscle-wall biopsy specimens and (2) determine if myenteric ganglia were present in the tissue samples. DESIGN AND INTERVENTIONS This was a preclinical acute study by using a pig model. Multiple samples were obtained from 4 pigs. The endoscopic techniques evaluated were (1) EUS-guided tru-cut biopsy of the gastric wall, (2) jumbo biopsy of the post-EMR site, (3) jumbo biopsy of the gastrotomy margin, (4) serosal-side biopsy through a gastrotomy, and (5) double-EMR resection. MAIN OUTCOME MEASUREMENTS Resected tissue was submitted for histology to determine which wall layers were included in the resected specimen. Hematoxylin and eosin staining was used to determine which muscle layers were biopsied, and an antibody to protein gene product 9.5 was used to determine if myenteric ganglia were present in the sample. RESULTS Seventy-two tissue samples were obtained: EUS-guided tru-cut biopsy (n=16), jumbo biopsy of the post-EMR site (n=16), jumbo biopsy of the gastrotomy (n=16), serosal-side biopsy (n=16), and double-EMR resection (n=8). Only the double-EMR resection tissues showed the presence of longitudinal muscle, indicating the presence of both muscle layers and the myenteric plexus. Immunofluorescence studies demonstrated the presence of myenteric ganglia only in the double-EMR tissues and in none of the other gastric samples. No adjacent organs were included in the resection. CONCLUSIONS The double-EMR technique was the only studied technique that resulted in a deep gastric-wall sample and provided sufficient tissue to evaluate both muscle layers and the intermuscular layer that contain myenteric ganglia. Further studies are needed to verify the efficacy and to assess the safety of this approach.

Abstract
OBJECTIVES Gastroparesis is an increasingly recognized disorder. Its prevalence in the United States is unknown. We examined the trends, characteristics, and outcomes of gastroparesis-related hospitalizations during 1995-2004. METHODS The publicly available Healthcare Cost and Utilization Project (HCUP) Nationwide Inpatient Sample (NIS) comprises a nationally representative sample of 5-8 million hospitalizations per year. Gastroparesis-related hospitalizations were identified using the International Classification of Diseases (ICD-9) code 536.3 and compared with other hospitalizations. Multivariate regressions were used to compare for differences in the outcomes including length of stay, total charges, and in-hospital deaths. RESULTS Hospitalizations with gastroparesis as the primary diagnosis increased from 3,977 in 1995 to 10,252 in 2004 (+158%) and hospitalizations with gastroparesis as the secondary diagnosis increased from 56,726 to 134,146 (+136%). These compared to smaller changes in diabetes-related hospitalizations (+53%), all hospitalizations (+13%), and hospitalizations with gastroesophageal reflux disease (GERD), gastric ulcer, gastritis, or nonspecific nausea/vomiting as the primary diagnosis (-3% to +76%). Of the five upper gastrointestinal conditions studied as the primary diagnosis, gastroparesis had the longest length of stay (+15.4% to +66.2%, all P < 0.001) and the highest or second highest total charges (-7.2% to +60.6%, all P < 0.01) in 2004, with similar results in 1995. CONCLUSIONS The number of gastroparesis-related hospitalizations has been increasing in the United States, suggesting an increasing prevalence of gastroparesis. The economic impact of gastroparesis-related hospitalizations is significant and increasing.

Abstract
BACKGROUND AND PURPOSE Endocannabinoids (via cannabinoid CB(1) receptor activation) are physiological regulators of intestinal motility and food intake. However, their role in the regulation of gastric emptying is largely unexplored. The purpose of the present study was to investigate the involvement of the endocannabinoid system in the regulation of gastric emptying in mice fed either a standard diet (STD) or a high-fat diet (HFD) for 14 weeks. EXPERIMENTAL APPROACH Gastric emptying was evaluated by measuring the amount of phenol red recovered in the stomach after oral challenge; CB(1) expression was analysed by quantitative reverse transcription-PCR; endocannabinoid (anandamide and 2-arachidonoyl glycerol) levels were measured by liquid chromatography-mass spectrometry. KEY RESULTS Gastric emptying was reduced by anandamide, an effect counteracted by the CB(1) receptor antagonist rimonabant, but not by the CB(2) receptor antagonist SR144528 or by the transient receptor potential vanilloid type 1 (TRPV1) antagonist 5'-iodoresiniferatoxin. The fatty acid amide hydrolase (FAAH) inhibitor N-arachidonoyl-5-hydroxytryptamine (but not the anandamide uptake inhibitor OMDM-2) reduced gastric emptying in a way partly reduced by rimonabant. Compared to STD mice, HFD mice exhibited significantly higher body weight and fasting glucose levels, delayed gastric emptying and lower anandamide and CB(1) mRNA levels. N-arachidonoylserotonin (but not rimonabant) affected gastric emptying more efficaciously in HFD than STD mice. CONCLUSIONS AND IMPLICATIONS Gastric emptying is physiologically regulated by the endocannabinoid system, which is downregulated following a HFD leading to overweight.

Abstract
Diabetes mellitus is rapidly increasing, diabetic patients are likely to undergo surgical procedures more than non-diabetic patients, the hospital stay of diabetic patients is longer, and diabetic patients have increased mortality and morbidity. The correct treatment of diabetic patients in the perioperative period is crucial to improve clinical outcomes. Diabetic patients must be carefully evaluated for cardiovascular risk, keeping in mind micro- and macroangiopathic diabetic complications. Metabolic control deserves great attention because hyperglycemia is related to increased complications and worse outcomes. Insulin infusion regimens to achieve near normoglycemia must be implemented in surgical and critically ill patients.

Abstract
BACKGROUND Although gastroparesis does not influence gastroesophageal reflux disease (GERD) or antireflux surgery, many patients with GERD will also suffer from gastroparesis-related bloating as a distinct symptom different from GERD-related symptoms. The purpose of this study was to assess whether a pyloroplasty with a fundoplication will improve bloating symptoms in these patients. METHODS A prospectively gathered database of all patients undergoing antireflux surgery was reviewed. All patients underwent history, physical examination, upper gastrointestinal endoscopy, esophageal manometry, 24-hour esophageal pH monitoring, and, selectively, contrast upper gastrointestinal radiography. Patients with symptoms of bloating also underwent gastric emptying scintigraphy. All patients completed the GERD-Health Related Quality of Life (HRQL) symptom severity questionnaire. One of the items of this instrument relates to bloating. The item is scored from 0 (asymptomatic) to 5 (incapacitating) based on descriptive anchors. Patients with symptomatic GERD and objective findings by physiologic testing were offered antireflux surgery. Those with delayed gastric emptying (defined as T(1/2) > 120 minutes) were also offered a pyloroplasty. Operations performed included a laparoscopic or open Nissen or Toupet fundoplication with a Heineke-Mickulicz pyloroplasty. Postoperatively, patients completed the GERD-HRQL and had a gastric emptying scintigraphy performed. RESULTS Three-hundred and sixty-nine patients underwent antireflux surgery; of these, 35 patients also had a pyloroplasty. Twenty-eight (80%) of these patients reported significant symptomatic improvement. The median preoperative bloating score improved from 4 to 1 postoperatively (P < 0.05), and the median gastric emptying scintigraphy T(1/2) improved from 244 to 112 minutes (P < 0.05). CONCLUSIONS Although gastroparesis may not contribute to symptoms of GERD, it can contribute to symptoms of bloating. Bloating symptoms improved in 80% of patients with the addition of a pyloroplasty. Therefore, addition of pyloroplasty to a fundoplication in patients with gastroparesis-related bloating can improve bloating symptoms.

Abstract
Gastroparesis is a chronic alteration of gastric motility characterized by symptoms suggestive of mechanical obstruction and delayed gastric emptying in the absence of obstruction. Gastroparesis can be idiopathic or attributable to neuropathy or myopathy as in diabetes mellitus and scleroderma or can occur after vagotomy. Diagnosis is based on symptoms (nausea, vomiting, abdominal distension and early satiety), physical examination (capotement) and on complementary investigations, the procedure of choice being isotope gastric emptying tests. Treatment depends on the clinical repercussions. In most patients, gastroparesis can be controlled by prokinetic drugs, dietary measures, exclusion of drugs that alter gastric emptying, and exhaustive control of blood glucose levels. In patients with severe gastroparesis, hospital nutritional measures (intravenous and/or enteral), gastric decompression and intravenous antiemetic and prokinetic agents are required. Aggressive nutritional therapies (parenteral or enteral nasojejunal nutrition), intrapyloric injection of botulinum toxin, implantation of a gastric stimulation device, or gastrectomy should only be used in patients unresponsive to conservative treatment or if there is selective alteration of gastric motility.

Abstract
BACKGROUND Small intestine video-capsule endoscopy examination in patients with diabetes mellitus may be incomplete due to delayed gastric emptying. AIM To measure video-capsule endoscopy gastric and small bowel transit time and to assess the completeness of the examination in diabetes mellitus patients. METHODS In this retrospective, case-control study, we examined capsule endoscopy videos from 29 consecutive diabetes mellitus patients. Fifty-eight matched for sex, type of preparation, age and reason for referral non-diabetic controls were selected from our video-capsule endoscopy database. Two independent experienced investigators measured transit times and assessed examinations' completeness. RESULTS Video-capsule endoscopy gastric transit time was significantly longer in diabetes mellitus (87, 1-478 min) compared to non-diabetic patients (24, 4-108 min, p<0.001). The caecum was visualized in 20/29 (69%) diabetes mellitus and 52/58 (89.6%) non-diabetic controls (p=0.02). In 16 diabetes mellitus patients that video-capsule endoscopy reached the caecum, small bowel transit time was significantly shorter (261.2+/-55.5 min) compared to their 32 non-diabetic matched controls (302+/-62.7 min, p=0.03). CONCLUSIONS Patients with type 2 diabetes mellitus have prolonged video-capsule endoscopy gastric transit time compared to non-diabetic patients. Prospective studies are required to complete our understanding of video-capsule endoscopy transit times in the setting of diabetes mellitus.

Abstract
Delayed gastric emptying is frequently observed in patients with long-standing type 1 and type 2 diabetes mellitus, and potentially impacts on upper gastrointestinal symptoms, glycaemic control, nutrition and oral drug absorption. The pathogenesis remains unclear and management strategies are currently suboptimal. Therapeutic strategies focus on accelerating gastric emptying, controlling symptoms and improving glycaemic control. The potential adverse effects of hyperglycaemia on gastric emptying and upper gut symptoms indicate the importance of normalising blood glucose if possible. Nutritional and psychological supports are also important, but often neglected. A number of recent pharmacological and non-pharmacological therapies show promise, including gastric electrical stimulation. As with all chronic illnesses, a multidisciplinary approach to management is recommended, but there are few data regarding long-term outcomes.

Abstract
Functional gastrointestinal disorders, such as functional dyspepsia (FD) and irritable bowel syndrome, are common pathologies of the gut. FD is a clinical syndrome defined as chronic or recurrent pain or discomfort of unknown origin in the upper abdomen. The pathophysiological mechanisms responsible for FD have not been fully elucidated, but new ideas regarding its pathophysiology and the significance of the pathophysiology with respect to the symptom pattern of FD have emerged. In particular, there is growing interest in alterations in gastric motility, such as accommodation to a meal or gastric emptying, and visceral sensation in FD. The mechanisms underlying impaired gastroduodenal motor function are unclear, but possible factors include abnormal neurohormonal function, autonomic dysfunction, visceral hypersensitivity to acid or mechanical distention, Helicobacter pylori infection, acute gastrointestinal infection, psychosocial comorbidity, and stress. Although the optimum treatment for FD is not yet clearly established, acid-suppressive drugs, prokinetic agents, eradication of H. pylori, and antidepressants have been widely used in the management of patients with FD. The therapeutic efficacy of prokinetics such as itopride hydrochloride and mosapride citrate in the treatment of FD is supported by the results of relatively large and well-controlled studies. In addition, recent research has yielded new therapeutic agents and modalities for dysmotility in FD, including agonists/antagonists of various sensorimotor receptors, activation of the nitrergic pathway, kampo medicine, acupuncture, and gastric electric stimulation. This review discusses recent research on the pathophysiology of and treatment options for FD, with special attention given to digestive dysmotility.
