Brief Summary

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)

Outcome Measures

Primary Outcomes (1)

  • Non-inferiority of a Short-POEM compared to a Long-POEM

    Treatment success, defined as an Eckard score ≤ 3. The Eckardt score is a clinical score for evaluating the severity of achalasia-related symptoms. Eckardt score varies between 0 and 12. Questions are asked about the frequency of dysphagia, regurgitation and retrosternal pressure sensation. Depending on whether any of these symptom occurrs, never, occasionally, daily or with each meal, a symptom score between 0 and 3 is applied. In addition a symptom score of 0-3 is assigned to the degree of weight loss (0 - No weight loss; 1 - weight loss \< 5Kg, 2 - weight loss between 5 and 10Kg, 3- weight loss \> 10Kg). Each symptom score (dysphagia, regurgitation, retrosternal pressure, and wieight loss) is summed to the other. Thus, a completely asymptomatic patient has a score of 0 and the most severely affected patient had a maximum score of 12.

Study Arms (2)

Short POEM

ACTIVE COMPARATOR

Patients in the Short POEM-group will undergo a Peroral Endoscopic Myotomy (POEM) extended for a total of 7 cm (including 4 cm above the esophago-gastric junction and 3cm on the stomach).

Procedure: Peroral Endoscopic Myotomy (POEM)

Long POEM

ACTIVE COMPARATOR

Patients in the Long POEM-group will receive a 12cm-long Peroral Endoscopic Myotomy (POEM), including 9 cm on the esophagus and 3cm on the gastric wall

Procedure: Peroral Endoscopic Myotomy (POEM)

Interventions

Peroral endoscopic myotomy (POEM) is a minimally invasive intervention for the treatment of esophageal achalasia. POEM includes different steps: 1. Lifting of the esophageal mucosa, with the injection of saline solution, and mucosal incision on the esophageal body (approximately 12 or 7 cm above the esophagogastric junction, for about 1-2cm) 2. Advance of the endoscope into the submucosa, repeated submucosal injection and dissection of a submucosal tunnel into the distal esophagus up to 3 cm into the gastric wall. 3. Myotomy of the distal esophagus, cardia and gastric wall, starting 3 cm below the mucosal incision 4. After the completion of myotomy, and check for mucosal integrity, the mucosal incision is closed using endoscopic clips
