Active clinical trials for "Esophageal Achalasia"

For the treatment of Achalasia, LHM has been the only surgical therapy. Recently, an endoscopic approach for this therapy has been developed (peroral endoscopic Myotomy POEM). Studies show promising short and mid term results for POEM. At present, POEM is considered a promising new technique with the potential to become a standard achalasia treatment. For this to happen, long-term comparative data with LHM is required. Therefore,the intention for this study is to investigate the short and long-term efficacy of POEM for the treatment of achalasia as it was performed in international centers and compare outcomes with database assessment of LHM.

Achalasia is a rare esophageal motility disorder, which is characterized clinically by symptoms of dysphagia, regurgitation, weight loss and chest pain. These symptoms are primarily caused by incomplete relaxation of a frequently hypertensive lower esophageal sphincter (LES) and to some extent by a lack of peristalsis in the tubular esophagus. Unfortunately, no therapy returns normal esophageal function. Treatment is therefore directed at lowering the LES pressure, with the aim of reducing the functional obstruction to bolus transit at this site. Current treatments can be endoscopic or surgical. Peroral endoscopic myotomy (POEM) has recently been described as a new minimally invasive endoscopic myotomy technique intending a permanent cure from primary achalasia in some centers. The investigators purpose was to further evaluate the efficacy and the feasibility of POEM for patients with achalasia in a prospective larger study.

Achalasia is a rare esophageal motility disorder, which is characterized clinically by symptoms of dysphagia, regurgitation, weight loss and chest pain. With respect to long-term efficacy, Heller myotomy (HM) using an open or a laparoscopic approach has gained wide acceptance as the procedure of choice for the management of patients with primary achalasia in recent years. Although good or excellent long-term symptomatic response rates can be achieved in more than 90% of patients undergoing HM, recurrence or persistence of symptoms occurs in approximately 20%. Controversy exists regarding the therapy of patients with failed success after HM. Peroral endoscopic myotomy (POEM) has recently been described as a new minimally invasive endoscopic myotomy technique intending a permanent cure from primary achalasia. Our purpose was to evaluate the efficacy and the feasibility of POEM for patients with failed HM.

The purpose of this study is to compare pneumatic dilatation and laparoscopic Heller myotomy in patients with achalasia in order to learn which of these two treatments should be recommended to patients in the future.

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.

POEM has recently described as an alternative treatment for achalasia in humans. In this procedure the esophageal sphincter is incised through a submucosal tunnel in the esophagus. In this study we aim to perform POEM on achalasia patients.

Patients who have had laparoscopic surgery for the treatment of achalasia will be asked to have pH studies done in order to determine is these patients suffer from reflux after surgery.

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 a primary esophageal motility disorder where the lower esophageal sphincter fails to relax in response to swallowing with no well understood underlying cause. Surgical myotomy represents an appropriate therapeutic option. The purpose of this study is to evaluate flexible endoscopic myotomy, a novel therapeutic approach to overcome the need for invasive surgery.

Achalasia is a rare motility disorder of the oesophagus that is characterized by aperistalsis of the oesophagal body and dysrelaxation of the lower oesophagal sphincter (LES). Current treatment is palliative, and the aim of the treatment is to diminish the obstructive function of the esophagogastric junction (EGJ). Due to this approach, the most frequent complication post-treatment is gastroesophageal reflux (GER). However, not every treated patient develops GER symptoms and the mechanism behind the occurrence of GER in treated achalasia are unclear. In this study, we aim to Investigate the incidence of reflux in patients after peroral endoscopic myotomy in patients with achalasia cardia.
