Filter by: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
Postoperative pain after peroral endoscopic myotomy occurs due to involuntary esophageal smooth muscle spasms. Magnesium has antispasmodic properties as a smooth muscle relaxant. This study hypothesizes that among patients having peroral endoscopic myotomy, magnesium will decrease postoperative esophgeal pain as measured by the esophageal symptoms questionnaire, while decreasing perioperative opioid requirements.
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.
Opioids act on opioid receptors located in the brain as well as in the gastrointestinal (GI) tract to induce changes in motility. A variety of studies have linked chronic opioid use with changes in intestinal and to a lesser extent esophageal motility. Less is known about acute administration effects on distal esophageal motility and LES and even less with respect to proximal esophagus, UES and pharynx. Codeine, an opioid receptor agonist, by acting both centrally as well as in the periphery may induce changes in parts of the GI tract implicated in deglutition. Therefore, to evaluate the hypothesis the researchers will study motility patterns in the pharynx, UES, proximal and distal esophagus and LES in 22 healthy volunteers receiving placebo or codeine (60 mg) in a double-blind randomized cross-over controlled fashion. Motility patterns will be studied using state-of-the-art criteria and analytic tools (Chicago 3.0, AIMPlot analysis).
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.
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.
Stress is well known to affect visceral sensitivity and gastrointestinal function in general. A majority of patients with gastroesophageal reflux disease (GERD) report stress as an important factor triggering symptom exacerbation. A real-life stressor could exacerbate heartburn symptoms in GERD patients by enhancing perceptual response to esophageal acid exposure. In Irritable Bowel Syndrome (IBS) patients, visceral hypersensitivity is a major pathophysiological mechanism and stress is shown to trigger or exacerbate symptoms. A possible mechanism of stressāinduced visceral sensitivity could be the barrier dysfunction. Indeed, in a study performed by our group, in human, an acute psychological stressor induces hyperpermeability in a mast cell dependent fashion and exogenous peripheral corticotrophin-releasing hormone (CRH) recapitulated its effects on barrier function. This increase in intestinal permeability is a phenomenon which appears as a prerequisite for visceral hypersensitivity. Furthermore, few studies indicate that human intestinal motility is probably modulated by CRH. It has been shown that the brain-gut axis in IBS patients has an exaggerated response to CRH.To our knowledge, the acute effect of exogenous CRH on esophageal motility has not been studied before.
This study aims to evaluate the efficacy and the safety of endoscopic injection of 100 IU of botulinum toxin (BTX) in the distal esophagus in patients with symptoms related to hypercontractile esophageal motility disorders.
Spastic esophageal motility disorders induced significant symptoms including dysphagia, retrosternal pain and regurgitation. Per oral endoscopic myotomy (P.O.E.M.) is a novel approach to perform myotomy through the esophagus with long submucosal tunnel. This study aimed to investigate the feasibility and safety of P.O.E.M. and translate the techniques from animal study to clinical practice in human.
Patients with difficulty in swallowing (dysphagia) or with reflux disease are frequently found to suffer from oesophageal hypomotility (weak contractions). Oesophageal motility is currently measured using high-resolution manometry (HRM). This technique has a 36 pressure sensors on a plastic tube to record the pressure in side the oesophagus. Several pharmaceutical agents (prokinetics) can stimulate oesophageal motility. However, use of prokinetics in patients with oesophageal hypomotility led to disappointing results. An explanation for these disappointing results is that inappropriate patients were targeted. The appropriate patient would be the one who still have some viable muscle in the oesophagus that can respond to pharmacological stimuli. In the process of developing treatment strategies in patients with oesophageal hypomotility, testing the preserved capacity of oesophageal muscles could be useful to predict the response of these patients to prokinetic drugs. The following tests have the potential to reveal the preserved capacity of the oesophageal muscle to respond to stronger/medicinal stimuli. 1. - Multiple rapid swallowing (MRS) of 5ml water boluses stimulates oesophagus. A normal response to MRS requires on the one hand integrity of neural mechanisms and on the other hand a functional oesophageal muscle. 2. - External abdominal compression can increase the resistance to bolus transport via oesophagus. The normal oesophagus produces contractions of higher amplitude and duration in order to maintain a normal bolus transit. 3. - Swallowing bread boluses require stronger oesophageal contractions for a successful bolus transit. The purpose of the proposed project is to firstly assess the effect of Azithromycin on oesophageal hypomotility and secondly to evaluate the predictive values of the stimulation techniques in predicting the likelihood the positive response to drug therapy.
