7 Clinical Trials for Various Conditions
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.
To test the idea that submucosal endoscopy is effective and safe for endoscopic myotomy, endoscopic submucosal dissection, and access for tissue acquisition and resection. Submucosal endoscopy is a recent innovative addition to gastrointestinal endoscopy. This involves endoscopic maneuvers in the gut wall, by dissection of the submucosal layer of GI tract, thereby allowing endoscopic myotomy (incision of the muscle), endoscopic access for tissue acquisition and therapy, and resection of precancerous and cancerous gastrointestinal tissue. This approach has been a dramatic game-changer for minimally invasive management of various gastrointestinal conditions such as Zenker's diverticulum, Achalasia, Spastic Esophageal Disorders, Gastroparesis, esophageal obstruction, Hirschsprung's Disease, and Gastrointestinal neoplasia. The aim of the proposed study is to prospectively assess technical success, clinical success, and adverse events after submucosal endoscopy. Technical success will be defined as ability to successfully complete the submucosal endoscopic procedure. Clinical success will be defined as symptom relief and objective evaluation which will be assessed with radiologic imaging, repeat endoscopy, gastrointestinal motility studies, and pathology results routinely performed post-procedure for clinical care, as indicated. Adverse events will be recorded per published ASGE criteria. A database/ registry of patients undergoing submucosal endoscopic procedures will be created to demonstrate this.
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.
Placement of a feeding tube through a gastrostomy can be performed endoscopically or radiologically. While percutaneous endoscopic gastrostomy (PEG) tube placement is most frequently performed using a "pull" technique, this method may not feasible in patients with malignant, or tight benign, esophageal stenosis. Further, the "pull" technique may drag tumor cells with the feeding tube and lead to implantation metastasis at the gastrostomy site. A clinical practice update by the American Gastroenterological Association has recommended that the pull-through PEG placement method should be avoided in all patients with oropharyngeal or esophageal cancer. It also recommends that the introducer/Push PEG method should be favored instead of the pull PEG. In such situations, an introducer-style, "Direct" gastrostomy tube can be placed endoscopically or radiologically. However, the published data comparing outcomes and safety of endoscopic "Direct" PEG (D-PEG) and interventional radiological PEG (IR-PEG) are very sparse. The D-PEG is performed under endoscopic visualization of the gastric wall which facilitates greater control and allows safe selection of gastrostomy site. Further, the presence of an endoscope enables transillumination to confirm the absence of intervening abdominal viscera between the abdominal wall and the anterior wall of the stomach. These advantages are lacking with the IR-PEG. We hypothesize that D-PEG is safer than IR-PEG. In this single center, non-randomized study, patients unable to undergo a conventional per-oral "Pull" PEG and needing a D-PEG will be prospectively enrolled. For the comparison arm, historical IR-PEG procedures at our center will be assessed. The technical success and rates of adverse events will be compared between the two arms. Approval from the Institutional review board has been obtained. Based on our experience, we estimate a sample size of 40 participants in each arm and anticipate completion of this pilot study by June 2021.
This study compares two treatments for Idiopathic Esophagogastric Junction Outflow Obstruction: pneumatic dilation compared with expectant management, on symptoms and liquid barium emptying exams.
The investigators propose a preliminary study performing exome sequencing on samples from patients and their biologically related family members with tracheal and esophageal birth defects (TED). The purpose of this study is to determine if patients diagnosed with TED and similar disorders carry distinct mutations that lead to predisposition. The investigators will use advanced, non-invasive magnetic resonance imaging (MRI) techniques to assess tracheal esophageal, lung, and cardiac morphology and function in Neonatal Intensive Care Unit (NICU) patients. MRI techniques is done exclusively if patient is clinically treated at primary study location and if patient has not yet had their initial esophageal repair.
POEM (per oral endoscopic myotomy) is effective for the treatment of swallowing disorders but can induce acid reflux. If acid reflux remains untreated in this situation, it can lead to significant problems. Thus, minimizing abnormal acid exposure after POEM is very important. Typically, this is done with acid suppression medications such as Prilosec or Nexium. However, long term acid suppression medication has been linked to possible long-term complications. Transoral incisionless fundoplication (TIF) has been approved for the treatment of reflux, but its use in reflux after POEM has not been investigated in detail. We hypothesize TIF will be able to decrease the amount of acid reflux in to the esophagus, thereby allowing patients to remain off of acid suppression medications. Once enrolled into the study, you will undergo the POEM procedure. 3 months after the procedure we will assess for abnormal reflux via questionnaires and diagnostic testing as part of the standard management post POEM. If there is evidence of abnormal reflux, the TIF procedure will be performed. 3 months after the TIF, you will have similar testing again to document resolution in abnormal acid reflux.You will be followed for 12 months as part of the study. If at the 3 month mark, there is no evidence of abnormal reflux, you will neither be placed on PPI nor undergo TIF and will be followed for 12 months to assess for abnormal reflux
