Introduction The most common etiologies of gastroparesis are typically understood to be post-infectious, post-operative, diabetic, and idiopathic (the latter often overlapping with post-infectious gastroparesis, which can be difficult to identify confidently by clinical history). Case series often frame idiopathic gastroparesis…
Introduction Idiopathic gastroparesis (IG) is defined as delayed gastric emptying with associated symptoms thereof without an identifiable cause. Although more than 90 possible causes of gastroparesis have been identified in the literature including case reports, the most common subsets are…
Introduction Postsurgical gastroparesis (PSG) is a syndrome of objectively delayed gastric emptying without mechanical obstruction following a surgical intervention on the stomach or esophagus. It most commonly results from a surgical disruption of the vagal pathways innervating the stomach and…
Introduction Type 1 and type 2 diabetes are associated with a variety of symptoms at all levels of the gastrointestinal tract, a phenomenon documented by Rundles as early as 1945 . Probably the best known gastrointestinal complication of diabetes is…
Introduction Gastroparesis presents with cardinal symptoms suggestive of delayed gastric emptying including nausea, vomiting, early satiety, postprandial fullness, bloating, visible distention, and upper abdominal pain. The diagnosis is made by documenting delays in gastric emptying on scintigraphy, breath testing, or…
Background This chapter will discuss the possible use and importance of antroduodenal manometry in the diagnosis and treatment of gastroparesis. As discussed in other chapters, gastroparesis is defined by symptoms of nausea, vomiting and abdominal pain. Generally there is a…
Introduction Electrogastrography refers to the noninvasive method for recording and analyzing gastric myoelectrical activity (GMA) from electrodes placed on the upper abdominal surface . Electrogastrography methods are used to record electrogastrograms (EGGs) which measure GMA. The normal frequency of GMA…
Magnetic resonance imaging for gastric motility and function Magnetic resonance imaging (MRI) is a valuable tool for visualization of the anatomy and the function of the digestive system in health and disease . Use of MRI in assessment of gastric…
Introduction Many providers are often faced with the decision of selecting the best test available from their armamentarium to diagnose gastroparesis. This can be challenging with recent evidence showing poor correlation between symptom relief and gastric emptying . There are…
Gastroparesis Background Gastroparesis is a chronic disorder characterized by delayed gastric emptying in the absence of mechanical obstruction, which results in typical symptoms of nausea, vomiting, bloating, abdominal distention, postprandial fullness, early satiation, and upper abdominal pain . Population-based studies…
