Code:

NCT07293650

Conditions

Type I Achalasia

Tailored Short Myotomy

Study Details

Brief summary:

The goal of this clinical trial is to learn if shorter Per-Oral Endoscopic Myotomy (POEM) works as well as a longer POEM in patients with trouble swallowing due to certain conditions. The main question\[s\] it aims to answer \[is/are\]:

  • Does making a smaller cut in the muscle at the bottom of the esophagus work just as well as making the standard bigger cut in relieving symptoms?
  • Does making the smaller cut reduce the side effects of the procedure compared to the standard bigger cut? Researchers will compare the symptoms and side effects of making a shorter cut to the symptoms and side effects of a longer cut.

Participants will allow researchers to access their standard of care information in their medical record, complete questionnaires at up to 6 times over a 2-year period.

Interventions and Outcome Measures

Arms

active comparator: Standard Myotomy

experimental: Tailored Short Myotomy

Interventions

Standard Myotomy

Myotomy during POEM of 8-10 cm in length, extending 2-3 cm into the gastric cardia; intention to perform selective circular myotomy, but allowing full thickness myotomy. FLIP is used to confirm adequate myotomy.

Tailored Short Myotomy

Myotomy during POEM of 4-5 cm in length, extending 1-2 cm into the gastric cardia; intend to perform selective circular myotomy, but allowing full thickness myotomy. FLIP is used to confirm adequate myotomy.

Primary outcome measure

  • Clinical Response-Overall [ Time Frame: From enrollment to Year 2 ]
  • Clinical Response-by Sex [ Time Frame: From enrollment to Year 2 ]
  • Clinical Response-by Race [ Time Frame: From Enrollment to Year 2 ]
  • Clinical Response-by Ethnicity [ Time Frame: From Enrollment to Year 2 ]
