Breath tests (BTs) are important for the diagnosis of carbohydrate maldigestion syndromes and small intestinal bacterial overgrowth (SIBO). However, standardization is lacking regarding indications testing, test methodology interpretation results. A consensus meeting experts was convened to develop guidelines clinicians research.Pre-meeting survey questions encompassing five domains; indications, preparation, performance, results, knowledge gaps, were sent 17 clinician-scientists, 10...
This consensus statement from the members of American Neurogastroenterology and Motility Society Nuclear Medicine recommends a standardized method for measuring gastric emptying (GE) by scintigraphy. A low-fat, egg-white meal with imaging at 0, 1, 2, 4 h after ingestion, as described published multicenter protocol, provides information about normal delayed GE. Adoption this protocol will resolve lack uniformity testing, add reliability credibility to results, improve clinical utility GE test.
The diagnosis of gastroparesis implies delayed gastric emptying. diagnostic gold standard is scintigraphy, but techniques and measured endpoints vary widely among institutions. In this study, a simplified scintigraphic measurement emptying was compared to conventional normal values defined in healthy subjects.In 123 volunteers (aged 19-73 yr, 60 women 63 men) from 11 centers, scintigraphy used assess 99Tc-labeled low fat meal (egg substitute) percent intragastric residual contents 60, 120,...
To update and expand on previously published clinical practice guidelines for the treatment of cancer treatment-induced diarrhea.An expert multidisciplinary panel was convened to review recent literature discuss recommendations updating by this group in Journal Clinical Oncology 1998. MEDLINE searches were performed relevant since 1998 reviewed all members. The algorithm revised consensus.A early toxic deaths occurring two National Cancer Institute-sponsored cooperative trials irinotecan...

Summary Background Gastric emptying scintigraphy (GES) using a radio‐labelled meal is used to measure gastric emptying. A nondigestible capsule, SmartPill, records luminal pH, temperature, and pressure during gastrointestinal transit providing of time (GET). Aims To compare GES by assessing their correlation, GET for discriminating healthy subjects from gastroparetics. Methods Eighty‐seven 61 gastroparetics enrolled with simultaneous SmartPill GES. Fasted were ingested capsule [ 99m Tc]‐SC...
Sacral nerve stimulation has been approved for use in treating urinary incontinence the United States since 1997, and Europe both fecal (FI) 1994. The purpose of this study was to determine safety efficacy sacral a large population under rigors Food Drug Administration-approved investigational protocol.Candidates SNS who provided informed consent were enrolled Institutional Review Board-approved multicentered prospective trial. Patients showing > or =50% improvement during test received...
To determine if hiatus hernia (HH) contributes to the delayed clearance of acid from esophagus in patients with gastroesophageal reflux (GER), we performed simultaneous esophageal pH recordings and radionuclide studies three study populations: 12 GER HH, 5 no 8 subjects HH but symptoms. Acid was measured at cm. above manometrically located lower sphincter (LES) after injecting a 15-ml. bolus 0.1 N HCl 15 LES. The labeled 200 mu Ci 99mTc-sulfur colloid. also 10 LES injection 20 faster...
OBJECTIVES: Despite a lack of supportive data, stool form and frequency are often used as clinical surrogates for gut transit in constipated patients. The aim this study was to assess the correlation between characteristics (form frequency) healthy adults. METHODS: Apost hocanalysis performed on 110 subjects (46 chronic constipation) from nine US sites recording (Bristol Stool Scale) during simultaneous assessment whole-gut colonic by wireless motility capsule (WMC) radio-opaque marker (ROM)...
Colon transit (CT) measurements are used in the management of significant constipation. The radiopaque marker (ROM) method provides limited information.We proposed to validate wireless motility capsule (WMC), that measures pH, pressure and temperature, ROM measurement CT patients with symptomatic constipation evaluated at multiple centers. Of 208 recruited, 158 eligible underwent simultaneous colonic time (CTT) using (Metcalf method, cut off for delay >67 h), WMC (cutoff >59 h). study was...
