Gastrointestinal motility modulating drugs include all compounds which have pharmacological activity of modulating (stimulating or inhibiting) gastrointestinal motility. They are mainly used for the treatment of functional gastrointestinal diseases. Gastrointestinal motility modulating drugs include 5HT receptor agonists, antagonists, and antidopaminergic agents. Many new gastrointestinal motility modulating drugs are currently under investigation. The aims of this article are to review the mechanism of action, efficacy and side effects of the gastrointestinal motility modulating drugs.

Electrogastrography (EGG) is a non-invasive method for the measurement of gastric myoelectrical activity. It was first discovered in 1921 and popularized in 1990s. EGG is attractive because it is non-invasive. However, due to its non-invasive nature, there have also been controversies regarding validity and applications of EGG. The aim of this review is to discuss the methodologies, validation and applications of EGG. Pros and cons of EGG will also be discussed in detail. First, the gastric slow wave and its correlation with gastric motility are presented. The association between gastric dysrhythmia and impaired gastric motility is reviewed. Secondly the method for recording the electrogastrogram is presented in detail and pitfalls in the recording and analysis of EGG are discussed. Thirdly, findings reported in the literature demonstrating the accuracy of EGG in recording gastric slow waves and gastric dysrhythmia are reviewed and discussed. The correlation of the electrogastrogram with gastric contraction is carefully discussed. Finally, applications of EGG in a few major areas are reviewed.

Primary chronic intestinal pseudo-obstruction is a rare condition characterized by the symptoms and signs of the functional intestinal obstruction due to intestinal motility dysfunction in the absence of an anatomic obstruction. Megacystis associated with primary chronic intestinal pseudo-obstruction is very rare. Herein we report a case of megacystis associated with primary chronic intestinal pseudo-obstruction.

Stress is the non-specific systemic response that occurs when the body is stimulated by various factors, and it can affect multiple systems of the body. Recent studies have shown that gut microbiota is an essential part of human microecology, and plays a pivotal role in keeping the body healthy. Stress can result in gut dysbiosis by affecting the function of intestinal mucosal barrier, intestinal immune and gastrointestinal motility. This article reviewed the alteration of gut microbiota caused by stress and the possible mechanisms involved.

Manometry is a noninvasive diagnostic tool for identifying motility dysfunction of the gastrointestinal tract. Despite the great technical advances in monitoring motility, performance of the study in pediatric patients has several limitations that should be considered during the procedure and interpretation of the test results. This article reviews the clinical applications of conventional esophageal and anorectal manometries in children by describing a technique for performing the test. This review will develop the uniformity required for the methods of performance, the parameters for measurement, and interpretation of test results that could be applied in pediatric clinical practice.

Current scintigraphic tests of gastrointestinal motor function provides relevant pathophysiologic information, but their clinical utility is controversial. Many scintigraphic methods are developed to investigate gastrointestinal motility from oral cavity to colon. These are esophageal transit scintigraphy, oropharyngeal transit study, gastric emptying test, small bowel transit time measurement, colon transit study and gastroesopahgeal reflux scintigraphy. Scintigraphy of gastrointestinal tract is the most physiologic and noninvasive method to evaluate gastrointestinal motility disorders. Stomach emptying test is regarded as a gold standard in motility study. Gastrointestinal transit scintigraphy also has a certain role in assessment of drug effect to GI motility and changes after therapy of motility disorders. Scintigraphy provides noninvasive and quantitative assessment of physiological transit throughout the gastrointestinal tract, and it is extremely useful for diagnosing gastrointestinal motor dysfunction. This article reviews the current procedures, indications, significance and guidelines for gastrointestinal motility measurements by scintigraphy.
