Brief Summary

This prospective observational study aims to investigate the association between the autonomic dysfunction and hemodynamic instability during per-oral endoscopic myotomy under general anesthesia in achalasia patients. Per-oral endoscopic myotomy is known as the effective treatment for achalasia patients. During per-oral endoscopic myotomy, capnoperitoneum, capnomediastinum, and systemic CO2 accumulation can potentially impair hemodynamics. Moreover, it has been suggested that achalasia is associated with autonomic dysfunction. We hypothesized that patients with autonomic dysfunstion would esperience more hemodynamic instability during per-oral endoscopic myotomy compared with patients without autonomic dysfunction. In this prospective observational study, the autonomic function test will be performed before surgery, and advanced hemodynamic parameters will be recorded using EV1000 clinical platform (Edwards Lifesciences, USA) during surgery. The association between the autonomic dysfunction and hemodynamic instability during per-oral endoscopic myotomy will be analyzed.

Outcome Measures

Primary Outcomes (1)

  • Wobble of Systolic Arterial Pressure (SAP) during surgery

    Wobble of SAP will be calculated according to the following formula. Performance Error (PE (%)) = (measured SAP-reference SAP) × 100/reference SAP Median performance error (MDPE (%)) = median {PEi, i = 1, 2, 3…, N} Median absolute performance error (MDAPE (%)) = median {\|PE\| , i = 1, 2, 3…, N} (N, number of measured SAP) Wobble (%) = median{\|MDPE - PEi\|, i = 1, 2, 3…, N}(N, number of measured PE) reference SAP = 120 mmHg

    During the intraoperative period, from the enterance to the operating room to the emergence of anesthesia

Study Arms (2)

Patients with autonomic dysfunction

Achalasia patients who have autonomic dysfunction in the heart rate variability test (HRV test) performed preoperatively.

Procedure: Per-oral endoscopic myotomy

Patients with normal autonomic function

Achalasia patients without autonomic dysfunction in the heart rate variability test (HRV test) performed preoperatively.

Procedure: Per-oral endoscopic myotomy

Interventions

Per-oral endoscopic myotomy will be performed under general anesthesia. Per-oral endoscopic myotomy will be performed according to the standard care. General anesthesia will be conducted according to the standard care in our institution, and standardized as follows. * Monitoring: ECG, SpO2, noninvasive blood pressure, invasive blood pressure monitoring via radial artery cannulation, advanced hemodynamic monitoring (including cardiac output, cardiac index) uisng EV1000 clinical platform (Edwards Lifesciences, USA), anesthetic depth monitoring by SedLine Sedation monitor (Masimo corporation). * Anesthetic induction: Target controlled infusion (TCI) of Remifentanil (target 3.0 ng/mL), propofol 2 mg/kg IV, rocuronium 0.8 mg/kg IV * Anesthetic maintence: sevoflurane 0.9 age corrected MAC and remifentanil TCI (target range 1.0-4.0 ng/mL)
