Active clinical trials for "Esophageal Achalasia"

The purpose of this study is to determine the efficacy and safety of peroral endoscopic myotomy (POEM) compared with pneumatic dilation in the treatment of esophageal achalasia.

In patients with achalasia, the relationship between the perception of dysphagia, oesophageal emptying, lower oesophageal sphincter (LOS) distensibility and oesophageal circular and longitudinal muscle contraction is not clear. We aim to characterize oesophageal circumferential and longitudinal muscle contractility and LOS distensibility in patients with achalasia (either before or after treatment). This may allow an understanding of the mechanisms underlying persistent dysphagia and delayed oesophageal emptying after treatment.

This study compares the clinical efficacy of safety of circular myotomy and full-thickness myotomy guided by peroral endoscopic in treatment of incision length of ≤7cm and of ≥7cm in achalasia patients.

Achalasia cardia is a primary oesophageal motility disorder of unknown etiology. Recently, peroral endoscopic myotomy (POEM) has gained widespread acceptance as an effective treatment modality for achalasia. Major adverse events are uncommon with POEM. Since the operator works close to mediastinum during the POEM procedure, there is a potential for infectious complications. Therefore, intravenous antibiotics are universally used to prevent infection-related adverse events. There is no fixed protocol or duration of antibiotics for the same.

From clinical observation that some achalasia patients drink water to help swallow food, the investigators have proposed a systemic hot water drinking therapy. This study is to observe its efficacy on achalasia symptoms and explore its mechanism.

Peroral endoscopic myotomy (POEM) has recently been introduced as promising alternative to laparoscopic Heller myotomy for patients with idiopathic achalasia. Several technical modifications have been proposed but have not yet been tested in randomized trials.

In this study, we will evaluate the incidence of reflux esophagitis between two different techniques of posterior per-oral endoscopic myotomy (POEM) i.e. conventional POEM versus oblique/ sling fiber sparing POEM. This is a randomized trial where the patients with idiopathic achalasia will be randomized in two groups in 1:1 fashion into groups.

Per-Oral Endoscopic Myotomy (POEM) is increasingly used for the treatment of achalasia. In published series, a 12cm-POEM is usually performed. Surgical myotomy is typically shorter (8cm). The clinical efficacy of both procedure is comparable. This study intends to investigate if clinical outcomes of POEM depends on the length of esophageal myotomy, in patients with classic-type achalasia (type I and type II according to Chicago Classification)

This study evaluates the efficacy and safety of the Per-Oral Endoscopic Myotomy (POEM) technique for lower esophageal sphincter myotomy in patients suffering from spastic esophageal disorders such as achalasia at a Canadian institution. The investigators hypothesize that POEM is a safe and effective technique for the surgical management of such disorders at our institution.
