Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Clinical success rates

    Clinical success is defined as a post-POEM Eckardt score ≤3 without additional treatment (Eckardt AJ et al, Nat Rev Gastroenterol Hepatol 2011).

    12 months after treatment

Secondary Outcomes (12)

  • Procedure-related adverse events

    baseline to 12 months after treatment

  • Procedure time

    POEM procedure

  • The volume of intraoperative bleeding

    POEM procedure

  • The use of hemostatic forceps

    POEM procedure

  • Postoperative pain requiring the use of tramadol

    Through hospital stay after procedure, an average of 2-7 days

  • +7 more secondary outcomes

EXPERIMENTAL

snare-assisted POEM

Device: snare-assisted POEM

ACTIVE COMPARATOR

knife-assisted POEM

Device: knife-assisted POEM

Interventions

POEM is performed by using a snare which is retracted into the sheath to expose the tip, leaving a 1-2mm length for operation. 1. After submucosal injection, an initial 2-cm mucosal incision is made by a snare in the posterior esophageal wall. 2. A submucosal tunnel from the esophagus to the gastric cardia is created using a snare. 3. Full-thickness myotomy is performed and extended 2-3 cm beyond the esophagogastric junction (EGJ) using a snare. 4. The mucosal incision is closed with endoclips.

snare group

POEM is performed by using a conventional endoscopic knife. 1. After submucosal injection, an initial 2-cm mucosal incision is made by a knife in the posterior esophageal wall. 2. A submucosal tunnel from the esophagus to the gastric cardia is created using a knife. 3. Full-thickness myotomy is performed and extended 2-3 cm beyond the esophagogastric junction (EGJ) using a knife. 4. The mucosal incision is closed with endoclips.
