Active clinical trials for "Esophageal Motility Disorders"

This study evaluates the effect of botulinum toxin 100 U or saline, injected endoscopically in the distal esophagus, on symptoms and manometry pattern in patients with diffuse esophageal spasm.

Achalasia and esophageal spasm are primary esophageal motility disorders where the lower esophageal sphincter fails to relax in response to swallowing with no well understood underlying cause. Surgical myotomy represents an appropriate therapeutic option. The purpose of this study is to evaluate flexible endoscopic myotomy a novel therapeutic approach to overcome the need for invasive surgery.

rimary spastic esophageal motility disorders, though uncommon, induce significant symptoms to patients including dysphagia, spastic chest pain, regurgitation as well as heartburn. The commonest causes of spastic esophageal motility disorders included Achalasia, hypertensive lower esophageal sphincter (LES), Nutcracker esophagus and Diffuse esophageal spasm (DES). Majority of these diseases were diagnosed by manometry. Achalasia is the most common primary esophageal motility disorder in which the LES failed to relax with increased pressure. Currently the standard treatment for Achalasia and spastic motility disorders is Laparoscopic Myotomy. The development of Natural Orifices Transluminal Endoscopic Surgery (N.O.T.E.S.) has lead to a new way to perform myotomy - Peroral Endoscopic Myotomy (P.O.E.M.). Basically, through mucosal incision, a submucosal tunnel is created after identification of the level of gastroesophageal junction. Myotomy will be performed with endoscopic instruments and the entrance site will be closed with clips.

No recommendation regarding antibiotic prophylaxis and preparation modalities are available for patients with esophageal motor disorders who benefit from Per-Oral Endoscopic Myotomy (POEM). The aim of our study was to evaluate the impact of antibiotic prophylaxis on the POEM's safety. This study was a comparative and multicentric retrospective analysis of a database prospectively maintained. Patients over 18 year's old with esophageal motor disorders confirmed by prior manometry, who underwent POEM were included. The primary endpoint was the occurrence of complications, as classified by Cotton, based on whether or not antibiotic prophylaxis was administered.

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

Noncardiac chest pain (NCCP) is a common clinical problem worldwide. In Hong Kong, it has been estimated that about 20% of patients with chest pain are misdiagnosed to have coronary heart disease. Despite its benign nature, this condition causes anxiety, impairs quality of life and consumes a substantial amount of healthcare resources. While acid reflux and motility disorder in the esophagus are often attributed as the cause of NCCP, visceral hyperalgesia of esophagus is now recognized to play a central role in the pathogenesis of this condition. This research project aims to evaluate the role of visceral hyperalgesia in Chinese patients with NCCP. NCCP patients will be evaluated for the prevalence of gastroesophageal reflux disease and esophageal motility disorder by endoscopy, manometry and pH study. The visceral sensory and pain thresholds of these patients will be compared with asymptomatic controls.

Chronic esophageal disorders affect approximately one third part of global population, with a deleterious impact in the quality of life of patients. Measured of health related quality of life in chronic esophageal conditions such as gastroesophageal reflux disease and achalasia are widely used to measure this important patient-reported outcome. The Northwestern Esophageal Quality of Life (NEQOL) is a hybrid measure of esophageal illness, allowing for broad use across esophageal diseases while maintain sensitivity to nuances of a specific condition. The NEQOL is a reliable and valid hybrid measure of disease specific health related quality of life across several chronic esophageal conditions. The Ecuadorian Institute of Digestive Diseases aims to translate and validate this survey into Spanish for its use in a Hispanic population. This cross-sectional study aims to translate, apply and validate the NEQOL in the patients attending in the esophageal division of the institute.

Gastroesophageal reflux disease (GERD) is involved in the development of esophageal motility disorders like Jackhammer esophagus (JE), a novel hypercontractile condition that was associated with progression to achalasia and limited outcomes following surgical anti-reflux therapy. This trial was designed to assess the prevalence and characteristics of JE in patients with typical symptoms of GERD and responsiveness to PPI therapy.

In the current study we plan to evaluate the effects of the conversion from gastric banding to gastric bypass on esophageal function using combined monitoring. The primary aim of the current study is to evaluate esophageal function before and 3-months after the conversion from gastric banding to gastric bypass. A second objective is to evaluate the severity of symptoms, esophageal dysmotilities, endoscopic abnormalities and bolus retention found in patients referred for conversion from gastric banding to gastric bypass. Our hypothesis is that esophageal motility disorders associated with gastric banding are reversed by conversion to gastric bypass.

The pronounced effect of goiter on the esophagus needs further exploration, as the mechanisms by which goiter leads to swallowing difficulties are unknown. By investigating esophageal motility using high resolution esophageal manometry before and after thyroidectomy we seek to examine the impact of the goiter mass on the esophagus and swallowing with six months follow-up.
