To simplify assessment of gastric emptying, we have developed a radiopaque barium marker method. The subjects were 11 healthy volunteers, 30 patients with progressive systemic sclerosis, 16 patients with dysmotility-like dyspepsia, 7 patients with irritable bowel syndrome, and 6 patients with diabetes mellitus. We tested three types of radiopaque markers with manometry by a three-channel strain gauge transducer. The 4.5-mm ring-shaped markers with a specific gravity of 1.2 were emptied from the stomach in correlation with the number of high-amplitude (>50 mm Hg) antral contractions. The percentage of residual markers at 2 hr was significantly (P < 0.05) lower in patients with irritable bowed syndrome than in normal controls, and at 5 hr it was significantly (P < 0.05) higher in patients with systemic sclerosis with esophageal dysmotility, dysmotility-like dyspepsia, or diabetes than in normal controls. This radiopaque barium marker method may be useful as a screening test for determining whether gastric emptying is rapid or delayed.

Despite the extensive impact of autonomic function on the gastrointestinal system, there is little understanding of the mechanisms by which specific autonomic abnormalities translate into particular gastrointestinal complaints. Three logical alternatives include: (1) the underlying disorder affects the autonomic and gastrointestinal systems independently; (2) autonomic dysfunction alters gastrointestinal processing directly; (3) gastrointestinal manifestations arise as a delayed, indirect consequence of autonomic dysfunction. The major gastrointestinal manifestations of dysautonomia include esophageal dysmotility such as achalasia, gastroparesis, and small bowel bacterial overgrowth in the upper tract. Lower tract disorders include diarrhea, fecal incontinence, and constipation. Sorting through the varied causes of these disorders requires a careful history and examination in each patient. Supportive diagnostic studies may include radionuclide imaging, motility examination, and electrogastrography. Autonomic studies can (1) distinguish a purely enteric from a more generalized dysautonomia; (2) provide surrogate information about motility; (3) differentiate primary (e.g., multiple system atrophy) from secondary (e.g., irritable bowel syndrome) dysautonomias as the etiology of gastrointestinal symptoms. Several new strategies are available for the treatment of gastroparesis, constipation, irritable bowel, and sphincteric incontinence.

Introduction Ehlers-Danlos syndrome (EDS), specifically the hypermobility type (hEDS), is associated with a variety of gastrointestinal (GI) conditions. This study aims to evaluate the prevalence of and factors associated with gut dysmotility in patients with hEDS. Methods This is a retrospective study of hEDS patients conducted at the Cleveland Clinic's Center for Personalized Genetic Healthcare between January 2007 and December 2017. Demographics, GI motility testing, endoscopic, and imaging data were extracted from the patients' charts. Results A total of 218 patients with hEDS were identified. Among them, 136 (62.3%) patients had at least one GI symptom at the time of EDS diagnosis. Motility testing was performed and reported in 42 (19.2%) patients. Out of them, five (11.9%) had esophageal dysmotility, 18 (42.8%) had gastroparesis, five (11.9%) had small bowel/colon altered transit time, and four (9.5%) had global dysmotility. In univariable analysis, patients with postural orthostatic tachycardia syndrome (POTS) [odds ratio (OR): 8.88, 95% CI: 3.69-24.9, p<0.0001], fibromyalgia (OR: 4.43, 95% CI: 2.04-10.1, p=0.0002), history of irritable bowel syndrome (OR: 5.01, 95% CI: 2.31-11.2, p<0.0001), and gastroesophageal reflux disease (OR: 3.33, 95% CI: 1.55-7.44, p=0.002) were more likely to be diagnosed with GI dysmotility. On multivariable analysis, only POTS (OR: 5.74, 95% CI: 2.25-16.7, p=0.0005) was significantly associated with an increased likelihood of GI dysmotility. Conclusions This study suggests that GI symptoms are relatively common among patients with hEDS. Of the patients tested for dysmotility, 76.2% were found to have some form of dysmotility. POTS was found to be an independent predictive factor for GI dysmotility.
