Filter by:The prospective clinical trial will study muscle fibrosis in relation to lower esophageal sphincter (LES) measurements on Functional Lumen Imaging Probe (FLIP) Topography (the novel technology that utilizes impedance planimetry) after pharmacologic challenge. A better understanding of achalasia will allow intervention at an earlier stage.
There will be a retrospective chart review for patients who underwent endoscopic procedures and POEM from 06/2016 - 01/2019 & a prospective chart review will be performed for patients who will undergo endoscopic procedures and POEM from 02/2019 - 06/2021
Esophageal achalasia is a precancerous condition for epidermoid carcinoma; incidence and risk factors for cancer development are not defined. Incidence and risk factors for epidermoid carcinoma development in achalasia patients were investigated.
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)
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.
Prospective Multicenter registry study to assess the safety and efficacy of clinically indicated peroral endoscopic myotomy (POEM) for the treatment of Achalasia
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.
This study will assess short and long term outcomes of individuals undergoing minimally invasive surgery of the gastro-esophageal junction (MISGEJ). Patients will respond to questionnaires on an annual basis evaluating quality of life and functionality following MISGEJ. Hospital charts will also be reviewed on an annual basis to assess patient health outcomes.
The aim of the study is to compare the efficacy of per-oral endoscopic myotomy (POEM) to the efficacy of pneumodilation as the initial treatment of symptomatic idiopathic achalasia. It is hypothesized that POEM has a higher long-term efficacy than pneumodilation in treatment of therapy-naive patients with idiopathic achalasia.
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.
