What this trial studies

This observational study aims to investigate the respiratory and hemodynamic effects during general anesthesia in patients with esophageal achalasia or gastroparesis who undergo endoscopic treatments like peroral endoscopic myotomy (POEM) or gastric peroral endoscopic myotomy (GPOEM). The study will assess the predictability of adverse events and the relationship between intra-abdominal pressure and changes in respiratory and hemodynamic parameters. Participants will receive standard care during the procedure, and the study will focus on collecting data related to complications associated with anesthesia. The findings could enhance understanding of anesthetic management in these procedures.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are scheduled for POEM or GPOEM procedures and classified as ASA risk 1 to 3.

Not a fit: Patients who are unable to follow study procedures due to language barriers, psychological disorders, or dementia may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the safety and effectiveness of anesthetic management during endoscopic treatments for esophageal and gastric motility disorders.

How similar studies have performed: While the approach of studying anesthetic management in these specific procedures is relatively novel, similar studies have shown the importance of understanding complications in endoscopic treatments.
