Abstract
Autonomic neuropathy in patients with diabetes mellitus, and especially complications related to gastrointestinal neuropathy, are often overlooked in the clinic. Diabetic gastroenteropathy affects every segment of the gastrointestinal tract and generates symptoms that may include nausea, early satiety, vomiting, abdominal pain, constipation, and diarrhea. Severe cases can be complicated by weight loss, dehydration, and electrolyte disturbances. The pathophysiology is complex, the diagnostics and treatment options are multidisciplinary, and there is generally a lack of evidence for the treatment options. The aims for this review are first to summarize the pathophysiology and describe possible and expected symptoms and complications.Further, we will try to supply the clinician with a straightforward tool for diagnostics, and then, we shall summarize established treatment options, including diet recommendations, pharmacological and non-pharmacological options. Finally, we will explore the multiple possibilities of novel treatment, looking at medications related to the pathophysiology of neuropathy, other manifestations of autonomic neuropathies, and symptomatic treatment for other gastrointestinal disorders, also including new knowledge of endosurgical and neuromodulatory treatment. The overall goal is to increase awareness and knowledge on this frequent diabetic complication and to provide better tools for diagnosis and treatment. Ultimately, we hope to encourage further research in this field, as there are clear shortcomings in terms of biomarkers, pathophysiology, as well as treatment possibilities. In conclusion, diagnosis and management of diabetic gastroenteropathy are challenging and often require multidisciplinary teams and multimodal therapies. Treatment options are sparse, but new pharmacological, endoscopic, and neuromodulatory techniques have shown promising results in initial studies.

Abstract
BACKGROUND/AIMS The aim of this study was to compare the effects of erythromycin infusion and gastric lavage in order to improve the quality of visualization during emergency upper endoscopy. METHODS We performed a prospective randomized pilot study. Patients presented with hematemesis or melena within 12 hours and were randomly assigned to the erythromycin group (intravenous infusion of erythromycin), gastric lavage group (nasogastric tube placement with gastric lavage), or erythromycin + gastric lavage group (both erythromycin infusion and gastric lavage). The primary outcome was satisfactory visualization. Secondary outcomes included identification of a bleeding source, the success rate of hemostasis, duration of endoscopy, complications related to erythromycin infusion or gastric lavage, number of transfused blood units, rebleeding rate, and bleeding-related mortality. RESULTS A total of 43 patients were randomly assigned: 14 patients in the erythromycin group; 15 patients in the gastric lavage group; and 14 patients in the erythromycin + gastric lavage group. Overall satisfactory visualization was achieved in 81% of patients: 92.8% in the erythromycin group; 60.0% in the gastric lavage group; and 92.9% in the erythromycin + gastric lavage group, respectively (p = 0.055). The identification of a bleeding source was possible in all cases. The success rate of hemostasis, duration of endoscopy, and number of transfused blood units did not significantly differ between groups. There were no complications. Rebleeding occurred in three patients (7.0%). Bleeding-related mortality was not reported. CONCLUSIONS Intravenous erythromycin infusion prior to emergency endoscopy for acute nonvariceal upper gastrointestinal bleeding seems to provide satisfactory endoscopic visualization.

Abstract
Gastroparesis is a very common condition, however many times it becomes difficult to manage even after long-term treatment due to multiple etiologies or improper therapy. Patients with severe gastroparesis are considered candidates for gastric electrical stimulants. The "Pulse Therapy" using metoclopramide and erythromycin to reprogram gastric motility can delay or even avoid the need for gastric electrical stimulants. This case report focuses on a patient with severe gastroparesis, who was considered for a gastric pacemaker implantation and was instead treated successfully with "Pulse Therapy." As a part of this regimen, he was given metoclopramide continuously for 3 months along with pulses of erythromycin for 10 days a month for 3 months. Patient recovered dramatically that he no longer remained a candidate for gastric pacemaker implantation. This case study emphasizes on how the proper use of prokinetic agents based on symptoms and gastric emptying study can reprogram the stomach motility in these patients with severe gastroparesis.

Abstract
The regulation of gastrointestinal motility mainly involves the smooth muscle, neural (extrinsic and intrinsic), and hormonal elements, the glial cells, and the interstitial cells of Cajal. An orchestrated function of all these components is required for the appropriate propulsive movement of the food in the gastrointestinal tract. Gastroparesis, a pathological slowing-down of gastric emptying, is a result of the damage to the tissue elements involved in the regulation of motility. Gastroparesis is one of the well-known complications of long-standing diabetes mellitus. Although it is rarely a life-threatening complication, it has a deteriorating effect on the quality of life, leads to unpredictable oscillation of the blood glucose level, and increases the time required for the absorption of food and medicines. This review describes the clinical characteristics of diabetic gastroparesis and summarizes the organic and functional motility abnormalities caused by this complication. Finally, the currently available and potential future therapeutic approaches are summarized.

Abstract
BACKGROUND Food residue in the remnant stomach after subtotal gastrectomy (STG) interferes with endoscopic observation. We investigated whether intravenous erythromycin improves gastric mucosa visualization in patients with STG. METHODS This study was conducted from April 2012 to October 2012 as a double-blinded, placebo-controlled, randomized trial. Patients who received STG with complete resection (stage T1-2N0M0) were included. Exclusion criteria were diabetes mellitus, neurologic disease, myopathy, recent viral enteritis history, concomitant therapy influencing gastrointestinal motility and severe comorbidity. Patients were instructed to consume a soft diet for dinner between 1800 and 2000 h, and endoscopies were performed between 0900 and 1200 h. Patients were assigned randomly to receive either erythromycin (125 mg in normal saline 50 cc) or placebo saline. The endoscopy was performed 15 min after infusion. Grade of residual food was rated as follows: G0, no residual food; G1, a small amount of residual food; G2, a moderate amount of residual food; G3, a moderate amount of residual food that hinders observation of the entire surface, even with body rolling; G4, a great amount of residual food such that endoscopic observation is impossible. RESULTS When good visibility was defined as G0+G1, visibility was significantly better in the erythromycin group (61 + 19 %) than in the placebo group (38 + 12 %, p < 0.001). However, this effect was not seen in patients within 6 months after gastrectomy. The risk factor for food stasis in the placebo group (n = 58) was food stasis at last endoscopy. The only factor predicting erythromycin response in the erythromycin group (n = 56) was elapsed time since surgery. Adverse effects included nausea [11 (19.7 %)] and vomiting [1 (1.8 %)] in the erythromycin group and vomiting [3 (5.2 %)] in the placebo group. However, they were transient and tolerable. CONCLUSIONS Premedication with erythromycin improves mucosal visualization during endoscopy in patients with STG. ( CLINICAL TRIALS REGISTRATION NUMBER NCT01659619).

Abstract
Gastroparesis is a prevalent condition that produces symptoms of delayed gastric emptying in the absence of physical blockage. The most common etiologies of gastroparesis are idiopathic, diabetic, and postsurgical disease, although some cases stem from autoimmune, paraneoplastic, neurologic or other conditions. Histologic examination of gastric tissues from patients with severe gastroparesis reveals heterogeneous and inconsistent defects in the morphology of enteric neurons, smooth muscle and interstitial cells of Cajal, and increased levels of inflammatory cells. Diagnosis is most commonly made by gastric emptying scintigraphy; however, wireless motility capsules and nonradioactive isotope breath tests have also been validated. A range of treatments have been used for gastroparesis including dietary modifications and nutritional supplements, gastric motor stimulatory or antiemetic medications, endoscopic or surgical procedures, and psychological interventions. Most treatments have not been subjected to controlled testing in patients with gastroparesis. The natural history of this condition is poorly understood. Active ongoing research is providing important insights into the pathogenesis, diagnosis, treatment and outcomes of this disease.

Abstract
AIM: To determine the efficacy and safety of erythromycin infusion prior to emergency endoscopy for acute upper gastrointestinal bleeding.
METHODS: A computer-based search of the Cochrane library, Medline, PubMed and China Journal Full-text database and a manual search of Gastroenterology Week and the American Gastroenterological Association Conference Proceedings to identify relevant controlled trials, regardless of language. The references were manually retrieved according to reference index. The randomized controlled trials that evaluated the use of erythromycin in endoscopy for acute upper gastrointestinal bleeding were included in our study. A meta-analysis was conducted using the method for Cochrane systematic review.
RESULTS: Three trials involving 245 patients were included in the systematic review. The meta-analysis showed that erythromycin was superior to placebo in gastric emptying and second-look endoscopy (OR = 5.10 and 0.48; 95%CI: 1.96-13.27 and 0.27-0.88; P = 0.0008 and 0.02, respectively), but no more effective than placebo in mean duration of endoscopy, mean blood transfusion volume and mean hospital stay (P = 0.84, 0.07 and 0.36, respectively). No complications were observed in all patients.
CONCLUSION: Erythromycin infusion is effective and safe in improving endoscopic view in patients with acute upper gastrointestinal bleeding.

Abstract
Gastroparesis presents with nausea, vomiting, early satiety and abdominal discomfort, as well as a range of nongastrointestinal manifestations in association with delays in gastric emptying. The disorder may be a consequence of systemic illnesses, such as diabetes mellitus, occur as a complication of gastroesophageal surgery or develop in an idiopathic fashion and may mimic other disorders with normal gastric emptying. Some cases of idiopathic gastroparesis present after a viral infection. Management relies primarily on therapies that accelerate gastric emptying or reduce vomiting, although endoscopic or surgical options are available for refractory cases. Current research is focusing on the cellular and molecular mechanisms underlying development of delayed gastric emptying, as well as factors unrelated to motor dysfunction that may elicit some symptoms. Future pharmaceuticals will target the contractile and nonmotor defects via novel pathways. Novel electrical stimulation techniques will be employed either alone or in combination with medications.

Abstract
Gastroparesis presents with gastrointestinal symptoms and nongastrointestinal manifestations in association with objective delays in gastric emptying. The condition may complicate several systemic disorders or may be idiopathic in nature. The diagnosis is made by directed evaluation to exclude organic diseases, which can mimic the clinical presentation of gastroparesis coupled with quantification of gastric emptying. Current therapies rely on dietary modifications, medications to stimulate gastric evacuation, and agents to reduce vomiting. Endoscopic and surgical options are increasingly used for cases refractory to medication treatment.

Abstract
Chronic gastroparesis and CIP are debilitating disorders that are difficult to treat with currently available therapies. Failure of proper migration and differentiation of enteric neurons or ICC can result from specific genetic mutations and lead to phenotypes of CIP with or without concomitant gastroparesis. Intestinal dysfunction in diabetes may reflect a depletion of NO production (and perhaps other neurotransmitters or modulators), which is manifest as a syndrome of gastroparesis, diarrhea, or constipation in individual patients. As the key molecular changes underlying these disorders are defined, clinicians will begin to understand their precise etiology and rational medical therapy may become possible. In the future, testable hypotheses regarding the etiology of other functional bowel disorders (e.g., functional dyspepsia, irritable bowel syndrome, and so forth) may be developed.

Abstract
Motor disorders of the gastrointestinal tract are characterized by definable impairments of gut contractile function. Other conditions exhibit specific disturbances of visceral afferent and efferent activity, which may underlie selected symptom complexes. Medications in several classes have been developed to treat these disorders of gastrointestinal function. Prokinetic agents are effective therapies for ailments with reduced motor function, whereas antispasmodic drugs reduce symptoms in conditions with exaggerated pressure wave activity. Recently, medications designed to blunt transmission in visceral sensory pathways have been proposed for use in the functional bowel disorders. Finally, some patients may benefit from initiation of nonspecific therapies, which have no appreciable effect on gut motor or sensory function.

Abstract
BACKGROUND Antropyloric motility is important for regulation of gastric emptying and has not been adequately characterised in premature infants. AIM To evaluate fed patterns of antropyloric motility in premature infants. SUBJECTS Forty three healthy premature infants, 30-38 weeks of postmenstrual age. METHODS Postprandial antropyloric motility was measured using a micromanometric feeding assembly (outer diameter 1.8 mm) incorporating a pyloric sleeve sensor. The occurrence of isolated pyloric pressure waves (IPPWs) and antral pressure wave sequences (PWSs) was characterised. Sequences were further classified as being antegrade, synchronous, antegrade-synchronous, and retrograde according to the direction of propagation. RESULTS A total of 7289 pressure wave events were recorded, 48% IPPWs and 52% PWSs (18% antegrade, 12% synchronous, 13% antegrade-synchronous, 2% retrograde, and 7% undefined). IPPWs predominated in the first postprandial hour, peaking at 30-60 minutes. PWSs predominated in the period after one hour postprandially. Mean (SEM) half gastric emptying time was 42 (4) minutes. CONCLUSIONS Monitoring of antropyloric motor patterns in healthy premature infants indicates that the neuroregulatory mechanisms responsible for the coordination of antropyloric motility and gastric emptying are well developed by 30 weeks of postmenstrual age.

Abstract
BACKGROUND & AIMS Emergency endoscopy may be difficult in upper gastrointestinal bleeding when blood obscures the visibility. Erythromycin, a motilin agonist, induces gastric emptying. We investigated whether an intravenous bolus infusion of erythromycin would improve the yield of endoscopy in these patients. METHODS Patients admitted within 12 hours after hematemesis were randomly assigned to erythromycin (250 mg) or placebo, 20 minutes before endoscopy. The primary end point was endoscopic yield, as assessed by objective and subjective scoring systems and endoscopic duration. Secondary end points were the need for a second look, endoscopy-related complications, blood units transfused, and length of hospital stay. RESULTS Fifty-one patients received erythromycin and 54 received placebo. A clear stomach was found more often in the erythromycin group (82% vs. 33%; P < 0.001). This difference remained significant in patients with cirrhosis. Erythromycin shortened the endoscopic duration (13.7 vs. 16.4 minutes in the placebo group; P = 0.036) and reduced the need for second-look endoscopy (6 vs. 17 cases; P = 0.018). Length of hospital stay and blood units transfused did not significantly differ between the 2 groups. No complications were noted. CONCLUSIONS Erythromycin infusion before endoscopy in patients with recent hematemesis makes endoscopy shorter and easier, thereby reducing the need for a repeat procedure.

Abstract
BACKGROUND Motilides have prokinetic effects on the upper gut during fasting, increasing the strength of antral contractions and stimulating gastroduodenal phase 3 sequences. Effects on the distal gut, and postprandially, are less well documented. AIM To evaluate dose-response effects of motilin and erythromycin on gastric emptying, small bowel and colonic transit in the dog using a validated scintigraphic technique. METHODS For gastric emptying and small bowel transit, 99mTc labelled beads were added to a meal of dog chow (450 kcal). Regional colonic transit was measured by 111In labelled beads placed in a capsule which dissolved and released radiation into the proximal colon. Scintiscans were taken at regular intervals and indices of whole-gut transit were calculated. Drugs were given by slow intravenous administration. RESULTS In the doses used, motilin accelerated regional colonic transit but did not hasten gastric emptying or small bowel transit. Single or repeated doses of motilin had similar effects on colonic transit. Erythromycin accelerated gastric emptying, small bowel transit and regional colonic transit. CONCLUSIONS Motilin receptors are apparently present in the canine small bowel and colon. Postprandially, motilides accelerate transit in the distal gut.

BACKGROUND Erythromycin is a motilin agonist and its effects on gastrointestinal motility are dependent on both dose and whether it is administered during the postprandial or fasting state. AIM To study the motility response of the small bowel to a low dose of intravenous erythromycin after meal intake and during fasting. METHODS Eighteen healthy subjects with mean age of 25 years were studied by small bowel manometry. Erythromycin was administered intravenously (0.75 mg per kg body weight) during 20 min in the postprandial (n=9) and the fasting state (n=9), and the motility response was recorded. RESULTS Erythromycin significantly reduced the frequency of propagated contractions (P < 0.001) and the amplitude of contractions (P < 0.02) in the small bowel during established postprandial motility. During the fasting state, erythromycin invariably initiated a phase III-like activity, which was similar to the spontaneous nocturnal phase III and migrated significantly more slowly than the diurnal phase III (P < 0.01). CONCLUSIONS A low dose of erythromycin administered intravenously during the postprandial state significantly inhibits small bowel motility, whereas administration during the fasting state initiates a phase III resembling the nocturnal rather than the diurnal phase III. These effects of erythromycin may indicate interference with vagal pathways. Due to its inhibitory effects, the clinical use of erythromycin in patients with hypomotility should be reconsidered, and the potential usefulness of these effects in patients with exaggerated intestinal motility deserves further attention.

Abstract
OBJECTIVE The aim of this study was to determine whether variations in the blood glucose concentration within the normal postprandial range affect the gastrokinetic action of erythromycin. METHODS Six healthy male volunteers, aged 20-33 yr underwent measurements of gastric emptying on 2 separate days; blood glucose concentrations were maintained at approximately 4 mmol/L (72 mg/dl) on 1 day and at 8 mmol/L (144 mg/dl) on the other. The order of the two studies was randomized and they were separated by 4-7 days. On both days, erythromycin (3 mg/kg) was administered intravenously over 15 min immediately before consumption of 300 g minced beef labeled with 20 MBq 99mTc-sulphur colloid chicken liver and 150 ml water labeled with 67Ga-EDTA. RESULTS Gastric emptying of solid (p < 0.05) and liquid (p < 0.0001) were slower at a blood glucose concentration of 8 mmol/L (144 mg/dl) when compared to 4 mmol/L (72 mg/dl). The slowing of gastric emptying was associated with greater retention of both solid and liquid in the proximal (p < 0.06) and distal (p < 0.01) stomach. CONCLUSIONS After administration of erythromycin, gastric emptying and intragastric distribution of solids and liquids is influenced by physiological changes in the blood glucose concentration.

Abstract
Scintigraphic techniques can measure sequentially gastric emptying, small bowel transit, and colonic transit in humans, and comparable methods for experimental studies in animals would be useful. We developed such a method in dogs and examined the effects of prokinetic drugs on regional transit. Two isotopes were given to fasting dogs. Polystyrene pellets labeled with 99mTc were mixed in a can of dog food and 111In- labeled pellets were given in a gelatin capsule coated with a pH-sensitive polymer, designed to dissolve in the distal bowel. Gamma camera images were obtained for up to 24 h. Prokinetic drugs were given by intravenous injection. Duplicate baseline studies showed good agreement in seven dogs. In a second group (n = 4), intra- and interanimal variabilities were established. Two novel prokinetic drugs (AU-116 and AU-130) accelerated small bowel and colonic transit. A simple noninvasive method for measuring whole gut transit in dogs was developed and validated. Two new prokinetics accelerated small bowel and colonic transit.

Abstract
Functional gut disorders include several clinical entities defined on the basis of symptom patterns (e.g., functional dyspepsia, irritable bowel syndrome, functional abdominal pain, functional abdominal bloating), for which there is no established pathophysiological mechanism. Because there is no well-defined pathophysiological target, treatment should be aimed at symptom improvement. Prokinetics and antispasmodics have been widely used in the treatment of functional gut disorders on the assumption that disordered motility is the underlying cause of symptoms, and symptom improvement is indeed achievable with these compounds in some, but not all, patients with features of hypo- or hypermotility, respectively. In the first part of this review, we cover the basic pharmacology and discuss the rationale for the clinical use of prokinetics and antispasmodics. On the other hand, in the past few years, the explosive growth in the research focusing on visceral sensitivity and visceral reflexes has suggested that at least some patients with functional gut disorders have altered visceral perception. Thus, the second part of the review covers these developments and focuses on studies addressing the issue of drugs modulating visceral sensitivity.

Abstract
BACKGROUND Erythromycin is a macrolide antibiotic that exhibits prokinetic effects. It has been shown to enhance antral contractility and accelerates gastric emptying rates, primarily by stimulating motilin receptors. AIM To determine the optimal dosage form of erythromycin for use as a prokinetic agent. METHODS Eight normal volunteers and three patients with documented gastroparesis ingested 250 mg erythromycin in tablet. suspension and intravenous forms. Serum erythromycin levels were determined at frequent intervals. These data were plotted vs. time and analysed for lag time, time to maximum concentration (tmax), maximum concentration (Cmax) and bioavailability (F). RESULTS The absorption kinetics of the erythromycin suspension was notable for short lag times and early tmax, while lag times and tmax were delayed with the tablet form. Median lag time was 15 min for the suspension vs. 90 min for the tablet (P < 0.005). Median tmax for the suspension was 45 min vs. 180 min for the tablet (P < 0.005). A non-significant decrease in F was seen with the suspension compared to the tablet (P = 0.12). CONCLUSION Based on the kinetic data from this study, erythromycin suspension is the ideal dosage form for administration of this drug as a prokinetic agent.

Abstract
BACKGROUND & AIMS EM523, a motilin agonist, is intended to be used as a gastroprokinetic during the postprandial period, but the mechanism(s) by which EM523 stimulates postprandial contractions in the stomach has not been studied before. The aim of this study was to examine the mechanism of contraction-stimulating activity by EM523 in fed dogs. METHODS Contractile activity in the gastric antrum of 5 dogs was monitored using a long-term implanted force transducer and measured by integrating the area under the curve. Test materials were continuously infused or injected intravenously. RESULTS EM523 (1-30 micrograms/kg) induced a dose-dependent increase in fed-type contractions. EM523-induced contractile activity was partially inhibited by atropine, hexamethonium, dopamine, 5-hydroxytryptamine 3 (5-HT3) receptor antagonist, and substance P antagonist. Atropine-resistant and EM523-induced contractions were further inhibited by 5-HT3 receptor antagonist and substance P antagonist, and the combined use of the two antagonists completely eliminated the atropine-resistant and EM523-induced contractions. CONCLUSIONS EM523-induced contractions in the fed stomach are quite different from phase III contractions in the fasted state and are mediated partially through the cholinergic pathway. The noncholinergic pathway involves 5-HT3 and neurokinin 1 receptors.

Abstract
The myoelectrical and motor response of the antropyloroduodenal region to intraduodenal nutrient stimulation or antral tachygastria represent useful models for, respectively, physiological and pathophysiological gastric stasis to test the efficacy of prokinetic drugs. We evaluated the effects of an intravenous bolus of cisapride (0.63 mg/kg) on the myoelectrical and motor response of the antropyloroduodenal region to an intraduodenal triglyceride emulsion (10% Intralipid, 0.5 ml/min) or antral tachygastria in conscious dogs. Intraduodenal lipid suppressed antral motility (P < 0.05, compared to intraduodenal saline) and stimulated phasic pyloric contractions (P < 0.01, compared to intraduodenal saline), a motor pattern known to be associated with delayed gastric emptying. During intraduodenal lipid stimulation cisapride virtually abolished all isolated pyloric motor events (P < 0.05) and stimulated antral and duodenal motility (P < 0.05 for both) and antropyloroduodenal coordination (65% versus 15%; P < 0.05). Antral tachygastria was associated with a higher number of isolated pyloric motor events in the fasted state [0.8 (0.7-1.1) per minute versus 0.2 (0-0.3) per minute; P < 0.05], but not during intraduodenal lipid stimulation [1.1 (0.9-1.7) per minute versus 1.2 (1.0-1.9) per minute; NS]. Cisapride decreased the number and duration of spontaneous episodes of antral tachygastria during intraduodenal saline and lipid infusion (P < 0.05 for both) and abolished the tachygastria-associated motor patterns. Cisapride induced a 20% decrease in the antral slow-wave frequency during intraduodenal saline and lipid, irrespective of gastric pacemaker rhythm. We conclude that: (1) cisapride overcomes feedback from small intestinal lipid receptors on myoelectrical and motor activities of the antropyloroduodenal region and decreases antral slow-wave frequency, and (2) cisapride inhibits antral tachygastria and tachygastria-associated motor patterns. These effects may contribute to the effective gastrokinetic properties of cisapride in physiological and certain forms of pathophysiological gastric stasis.
