Filter by:The purpose of this study is to compare the safety and efficacy of the anterior versus posterior myotomy technique in Per Oral Endoscopic Myotomy (POEM) for the treatment of Achalasia. The primary efficacy outcome is periprocedural pain requiring the use of narcotics. The secondary outcomes focus on safety which includes technical procedure duration time; tunneling time, myotomy time, and closure time; incidence of mucosotomy (transmural and non-transmural injury), capnoperitoneum, and the postoperative sequelae of gastrointestinal reflux disease (GERD). Periprocedural pain data collection will include post POEM procedure pain scores, administrations of analgesia until discharge. The final analysis will focus on determining whether there is a statistically significant difference in the amount and severity of pain in the Anterior versus Posterior myotomy subject populations. Additional analysis will be the collection of analgesic type (narcotic versus non-narcotic), dosage, frequency, and duration of treatment from post POEM procedure in the endoscopy recovery suite until the subjects are discharged.
Aim of this study is to compare the outcomes of a short esophageal myotomy extending from 3 cm cephalad to the EGJ, to 3 cm distal to it with a long esophageal myotomy with an additional proximal extension (at least 6 cm cephalad to the EGJ, to 3 cm distal) for POEM procedures. Principle of POEM is to reduce pressure gradient across LES by Myotomy. Hypothesis is that performing short myotomy will result in similar efficacy in achalasia cardia while reducing the total time taken for the procedure and ultimately will result in less complications.
POEM is a new intervention for the treatment of achalasia and has been reported to relieve the dysphagia symptom effectively. Although the cost of POEM method is less than the method of Laparoscopic Heller Myotomy and Fundoplication, it is still of an economic burden for the patients with achalasia. In this trial, investigators plan to use snare to assist POEM procedure, to observe the safety, efficacy and cost-effectiveness of this method, compared with other knifes-assisted procedure.
Achalasia is an esophagus motor disability characterized by a lack of relaxation of the lower esophageal sphincter (LES) to deglutition. Myotomy is the gold standard surgical technique allowing to cure this pathology. In this study, investigators are using a new endoluminal technique of myotomy, innovative and less invasive, called POEM (PerOral Endoscopic Myotomy). This technique does not require any cutaneous incision. Mini-invasive surgery is more and more associated to endoscopy. The practice was initiated by the accession of natural orifice transluminal endoscopic surgery (NOTES). In this context, the introduction of the POEM technique seems to be an original approach and a natural evolution to a new generation of surgical endoscopy.
Per-oral endoscopic myotomy (POEM) is an incisionless procedure used to treat esophageal achalasia, performed by GI endoscopist without cutting any surface of the human body. The main constituent of the procedure is the myotomy part, through which the endoscopist cuts the muscle fibers in the submucosa. Since this procedure is completely new to the area of treatment of achalasia, it is unknown whether a posterior or an anterior myotomy is better in relieving the symptoms. Thenceforth, this study aims at randomizing patients with achalasia presenting for POEM to getting either the posterior or the anterior myotomy. Patients will be followed up for symptoms and complications; data will be extracted and the appropriate analysis will be employed to determine if there is any difference of outcome between the two techniques of myotomy.
The investigators wish to monitor the adoption of a new, incisionless approach to performing a Heller myotomy for the surgical treatment of achalasia. The method, the Peroral Endoscopic Myotomy (POEM), will provide less-invasive treatment for esophageal achalasia, ideally providing similar if not better outcomes (safety and efficacy) as the Heller myotomy. The investigators hope to enroll 10 patients with a clinical diagnosis of achalasia who meet inclusion criteria. The POEM procedure has been done in many hospitals without any research associated with it. Dr. Ginsberg, Dr. Chandrasekhara and Dr. Kochman will perform the procedures after being trained. Dr. Ginsberg has personally witnessed the performance of 10 POEM procedures and has performed in a swine model. The PI is credentialed to initiate POEM at HUP with the first case to be proctored by an experienced operator. The PI will then proctor the other adopters. The investigators would like to evaluate the safety of it and the effectiveness of it. The investigators will use their symptom scores and radiology tests pre- and post-POEM to evaluate effectiveness.
Treatment options for achalasia include endoscopic dilations and surgical myotomy. Recently the POEM (Per oral endoscopic myotoymy) technique has been described. Patients undergo myotomy under endoscopic control. It has advantage over endoscopic dilation since myotomy is performed, and has advantage over surgery because it is performed endoscopically, thus is less invasive. One potential disadvantage in respect to surgery may be that it may determine higher rates of post-operative reflux. The purpose of this study is to prospectively assess the feasibility of PEOM in our Center with the new hybrid knife, and clinical results at 1, 3 and 12 months. This is a prospective, phase II study. Ten patients (age 18-75 years old) with diagnosis of achalasia, without megaesophagus or colonic esophagus, will be included for the POEM procedure. This study will last about 2 years. The aim is the feasibility, security and success rate of POEM for achalasia. Patients will be followed for at least one year.
Patients with newly diagnosed achalasia have been submitted to either treatment with pneumatic dilatation or surgical myotomy. Minimal follow up five years.
This is a pilot study for a new endoscopic treatment of achalasia. Up to 25 patients will be recruited for this trial, with the intent to treat 20 patients.
Achalasia is a rare motor disorder of the gastroesophageal junction which is associated with an increased pressure of the esophageal sphincter. This leads to impairment to swallow and heartburn. Esophageal myotomy, which is a surgical longitudinal incision of the esophageal muscle layer extending over to the gastroesophageal junction is the treatment of choice for achalasia. In order to prevent reflux of stomach content into the esophagus this has to be combined with an antireflux procedure where the upper part of the stomach (fundus) is wrapped around the esophagus (fundoplication). This procedure can be performed with the wrapped fundus either in front of the esophagus (Dor procedure) or behind (Toupet). The latter introduces an angulation of the esophagus, which possibly may lead to an impairment of swallowing ability and passage of food to the stomach. On the other hand, the Toupet procedure may give a better control of reflux. The primary endpoint of the study is symptoms of impaired swallowing 1 year after treatment. Secondary outcomes include reflux (pH measurements in the esophagus), radiological imaging of swallowing and quality of life.
