Filter by: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 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.
Esophageal outflow obstruction is characterized by failure to relax the lower esophageal sphincter (LES), resulting in impaired flow of ingested food into the stomach. The subsequent stasis of ingested food leads to symptoms of dysphagia, regurgitation, chest pain, and weight loss. The core objective of the treatment of esophageal outflow obstruction is to disrupt the LES and reduce its pressure to allow esophageal emptying. Therapeutic options include pharmacologic therapy, Botulinum toxin injection, pneumatic balloon dilation, and surgical myotomy with partial fundoplication. In addition, peroral endoscopy myotomy (POEM) has recently been introduced as a minimally invasive treatment, but there have a few studies regarding long-term outcomes. The aim of this study is to evaluate clinical outcomes of POEM for esophageal outflow obstruction.
This is a study of an investigational surgical procedure for the treatment of achalasia the inability of smooth muscle to move food down the esophagus. A new procedure, called the POEM procedure (per oral endoscopic myotomy) has been developed for achalasia. This study is being performed to determine if patients can go home on the same day as their procedure.
Achalasia is an esophageal motility disorder, which leads to clinical symptoms such as dysphagia, regurgitation, chest pain and consecutive weight loss. Although conventional treatment such as laparoscopic Heller myotomy (LHM) and balloon dilatation (BD) can provide sufficient symptom relief in many patients, both interventions have their individual drawbacks. Additionally, treatment after failed LHM or BD can be challenging and in few might even lead to esophagectomy. Per oral endoscopic myotomy (POEM) and prolonged dilatation (PRD) are two novel endoscopically performed therapeutic options for achalasia and other esophageal motility disorders. Both not only appear to provide good results, when performed as initial treatment but also might be an excellent option after e.g failed LHM. The purpose of this study is to evaluate the long-term efficacy of four different treatment options, such as POEM, PRD with stent-fixation, PD and conventional LHM for achalasia in an individualized treatment setting.
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.
Prospective Multicenter registry study to assess the safety and efficacy of clinically indicated peroral endoscopic myotomy (POEM) for the treatment of Achalasia
The aim of this study is to compare efficacy of POEM and pneumatic dilatation in treatment of achalasia cardia.
Patient with achalasia have a 10-50 fold increased risk to develop esophageal squamous cell carcinoma (ESCC). Early diagnosis of ESCC is essential, and detection of an earlier dysplastic stage is preferred. Endoscopic detection is however difficult and often delayed. Chromoendoscopy with Lugol dye increases detection rates dysplasia and ESCC to 91-100%. The aim of this study was therefore to evaluate a screening program using chromoendoscopy with Lugol to detect dysplasia in patients with idiopathic achalasia. A second objective is to study the relationship between foodstasis and the development op dysplasia
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.
