2 Clinical Trials for Various Conditions
This study is designed to obtain data on the safety and efficacy of oral nitroglycerin solution for the treatment of esophageal food impaction in patients presenting to the Emergency Department with presumed esophageal food impaction. The main hypothesis is to determine the success rate of oral nitroglycerin solution in relieving the food impaction by assessing the resolution of symptoms and the ability of the patient to swallow.
This will be a prospective, observational, case-control study of adult patients presenting to the WellSpan York Hospital Emergency Department (YHED) with signs and symptoms of esophageal food or foreign body impaction. Point of care ultrasound (POCUS) will then be performed by a trained emergency physician to collect ultrasound data, including the presence or absence of direct visualization food bolus/foreign body, as well as secondary markers of dilatation, such as maximal esophageal area. Investigators will also enroll an age/sex-matched control group of asymptomatic individuals to establish baseline esophageal measurements. Patients will otherwise receive medical treatment per standard of care. Subsequent interventions will also be documented, including glucagon, carbonated beverages, and esophagogastroduodenoscopy (EGD). If patients remain in the ED and improve without need for EGD they will undergo repeat ultrasound. Chart review at 1 month will be performed to establish results of EGD including improvement, recurrence, or presence of pathologic abnormalities. The investigators aim to establish normal and abnormal parameters to aid in the diagnosis of esophageal food impactions to predict need for definitive EGD management.
