Investigating autonomic dysfunction and hemodynamic stability during a specific surgical procedure for achalasia

Effect of Autonomic Dysfunction on Hemodynamic Instability During Per-oral Endoscopic Myotomy in Achalasia Patients: a Prospective Observational Study

Observational Gangnam Severance Hospital · NCT05772260

This study is trying to see if patients with autonomic dysfunction have more blood pressure problems during a specific surgery for achalasia compared to those without this issue.

What this trial studies

This observational study aims to explore the relationship between autonomic dysfunction and hemodynamic instability in patients undergoing per-oral endoscopic myotomy for achalasia. The study will assess autonomic function prior to surgery and monitor advanced hemodynamic parameters during the procedure using specialized equipment. The hypothesis is that patients with autonomic dysfunction will experience greater hemodynamic instability compared to those without. This research could provide insights into patient management during surgery for achalasia.

Who should consider this trial

Good fit: Ideal candidates are patients aged 19 and older scheduled for per-oral endoscopic myotomy at Gangnam Severance Hospital.

Not a fit: Patients who are hemodynamically unstable prior to surgery or unable to undergo the necessary autonomic function tests may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the safety and outcomes of surgical procedures for achalasia patients by identifying those at higher risk for hemodynamic instability.

How similar studies have performed: While the specific approach of this study is novel, previous studies have indicated a potential link between autonomic dysfunction and surgical outcomes, suggesting that this area of investigation is relevant.
