Filter by:Peroral endoscopic myotomy (POEM) is a minimally invasive treatment for esophageal achalasia with a natural orifice transluminal endoscopic procedure and far less invasive than the standard surgical or laparoscopic Heller myotomy (LHM). Less is known about the postoperative pain after POEM and the minor surgery trauma, short length of stay may lead to underestimation of postoperative pain control. We tend to observe the pain status after the POEM surgery under the empirical treatment in our center, and find a proper intra-operative way of pain control to solve the post-operative pain and seek the possible influence factors of postoperative pain.
Therapy for end-stage achalasia is under debate: comparative data on the long-term functional results of myotomy and oesophagectomy are lacking. The study aimed to compare the objective outcomes and quality of life after oesophageal myotomy and oesophagectomy. The study included 31 patients (57 years) who underwent the Heller-Dor procedure with verticalisation of the distal oesophagus (pull-down technique dedicated to sigmoid oesophagus treatment) and 29 patients (recurrence free, 64 years) (p=0.539) who underwent oesophagectomy for end-stage achalasia or for cancer, extracted from a database designed for prospective clinical research. The objective outcomes of treatment were evaluated with semi-quantitative scales investigating dysphagia, reflux symptoms and endoscopic oesophagitis. Quality of life was assessed with the SF-36 questionnaire.
Achalasia is a primary esophageal motility disorder characterized on high-resolution manometry (HRM) studies by 100% failed peristalsis and elevated integrated relaxation pressure of the lower esophageal sphincter. It is further divided into 3 sub-types according to the Chicago classification v3.01. The pathophysiology of achalasia is poorly understood; however, the NGEU is increasingly recognized as playing a key role in the development of this disorder. Similarly, the esophageal muscle tissue is probably involved, but its sampling remained challenging until the recent advent of the POEM procedure. Indeed, it is now possible, easy and safe to take biopsies of the muscle tissue during POEM. Therefore, POEM not only represents an innovative and effective treatment for achalasia, but also an opportunity to better understand its underlying pathophysiological mechanisms. Currently available treatments for achalasia (pneumatic dilation (PD), Heller's myotomy (HM), botox injections, POEM) are "palliative" procedures that do not restore normal contractile function of the esophagus, but a better understanding of the pathophysiological mechanisms underlying this disorder could potentially help developing curative, or even preventative treatments. To date, muscle tissue sampled during a POEM has only been characterized qualitatively (normal, atrophic, hypertrophic) with no assessment of the enteric nervous system. Moreover, there has been no studies of the mucosal or NGEU anomalies on biopsies taken during a minimally invasive procedure for achalasia such as a POEM. This study aims to evaluate the feasibility of the assessment of NGEU and esophageal muscle tissue in biopsies taken during a POEM for achalasia. It also aims to determine whether specific biomarkers within the NGEU and muscle tissue can predict a better therapeutic response to a POEM. The goal is to include 30 patients within 12 months. Given that approximately 100 new cases of achalasia are diagnosed each year at the included centers, and that about 50% of treatment-naive patients are offered and accept to undergo a POEM, recruitment should be completed relatively rapidly. All POEMs will be performed at the CHU de Nantes by a single endoscopist who has already performed more than 100 procedures. Other than the complications related to the POEM itself, the addition of 14 esophageal biopsies required for our study is a very low-risk intervention. Biopsy sampling extends the length of the procedure by only 4-5 minutes and has not been associated with an increased risk of complications in a previous study. Patients will be evaluated at five time points: preinclusion visit (up to four months before the POEM), inclusion visit (day of the POEM), post-POEM phone calls (3-6, 9-12, 22-26 months after POEM). During the preinclusion visit, relevant information regarding inclusion/exclusion criteria, consent, HRM and pH impedance results, past medical history, and pregnancy status (if applicable) will be gathered. At each time point, current medical history, Eckhardt score2 and pH impedance results (if available) will be documented. The patient will also answer the quality of life (SF36)3 and nutritional status questionnaires and will undergo blood sampling for albumin and prealbumin levels. Additionally, on the day of the POEM, there will be another blood sampling for complete blood count, PT, APTT, serum electrolytes and CRP level. Finally, at each post-POEM phone calls, the occurrence of adverse events will be reported. Our primary hypothesis is that the analysis of mucosal and muscle tissue biopsies taken safely during a POEM will allow better characterization of transcriptomic and molecular remodeling of the mucosa (especially the NGEU) and the muscularis propria in achalasia. We also hypothesize that these anomalies could eventually serve as treatment targets and as a way of better stratifying patients according to achalasia type and treatment (in our case, POEM) response.
The peroral endoscopic myotomy for the treatment of achalasia is associated with a higher incidence of gastroesophageal reflux disease compared with Heller's myotomy. Remodeling of the esophagogastric junction with hybrid argon plasma could decrease the passage of gastric or gastroduodenal content into the esophagus.

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.
Researchers are reviewing and analyzing surgical and clinical outcomes of subjects who underwent POPE for end-stage achalasia, a sigmoid esophagus, or a redundant conduit that has been used to replace the esophagus. This data will help researchers determine the safety and efficacy of a novel minimally invasive treatment compared to invasive surgery.
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.
Achalasia is a disease characterized by lack of peristalsis and lower esophageal sphincter failing to relax. Longitudinal muscle, outer layer of esophageal smooth muscle, is recently found to be responsible for emptying of esophagus for achalasia patients, especially for those type Ⅱcases. Clinical observations also conclude that type Ⅱ achalasia which still preserve longitudinal muscle response best to treatment, among the 3 types. Thus, with high frequent intraluminal ultrasound, clinically applied as endoscopic ultrasound, to measure the function of longitudinal muscle in achalasia patients, the current research aims to explore the influence of longitudinal muscle on the prognosis of achalasia patients after peroral endoscopic myotomy, a routine treatment.
POEM (Peroral Endoscopic Myotomy) is an endoscopic procedure most commonly used to treat achalasia. Achalasia is a disorder resulting from the inability of esophageal muscles to relax.The POEM procedure, performed under general anesthesia, involves inserting an endoscope into the esophagus where a specialized knife is able to cut a new pathway through the esophageal tissue. The knife is then used to incise, and therefore loosen, tight muscles within the esophagus, lower esophageal sphincter, and the upper region of the stomach that are responsible for the symptoms.This study seeks to improve patient's post-operative pain levels by placing ropivacaine (a local anesthetic) into the newly cut pathway that is created in the POEM procedure. It is hypothesized that the topical irrigation of the POEM tunnel with ropivacaine will result in decreased pain scores and a decreased need for additional pain medications.
