About this study

Official title: Using the High Resolution Impedance Manometry to Evaluate Swallowing Function After Cervical Spine Surgery: Anterior vs Posterior Approach

Dysphagia is a well-known complication following cervical spine surgery, including anterior or posterior approach. However, which muscle at oropharyngeal region weakness and the recovery course of these patients are still unknown.

The high resolution impedance manometry (HRIM) could be used to measure the postoperative recovery esophageal function.

Read the detailed description

Dysphagia is a well-known complication following cervical spine surgery, including anterior or posterior approach. However, which muscle at oropharyngeal region weakness and the recovery course of these patients are still unknown.

The high resolution impedance manometry (HRIM) could be used to measure the postoperative recovery esophageal function.

In this study, using the high resolution impedance manometry to determine (1) whether the occurrence of dysphagia in the postoperative 1 or 7 days and 1 month in the patients receiving anterior vs posterior approach of cervical spine surgery (2) which muscle in the pharyngeal region would be destroyed Consecutive patients who will fulfill the criteria of cervical spine surgery patients under general anesthesia and aged >= 20 will be enrolled. The patients would receive the dysphagia questionnaire. All subjects would receive the swallowing function by HRIM before the surgeries. The cough test was also measured. After the surgery, the patient would be followed the swallowing function in the postoperative one day, and 1 week by HRIM and questionnaire.

This study would expect (1) that the posterior cervical spine surgery would result in dysphagia greater than baseline, but less than that of anterior cervical procedures; (2) decreasing upper esophageal sphincter (UES) pressure may be the reason of postoperative dysphagia in the anterior cervical spine surgery, resulted from the intraoperative traction; (3) decreasing hypopharyngeal muscle pressure may be the reason of postoperative dysphagia in the posterior spine surgery, resulted from the prone and flexion positioning.

Being tested

Questions about this trial

What is this clinical trial studying?

An observational study of Pharyngeal Pressure Change, run by National Taiwan University Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 0 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 11 Oct 2019. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Chih-Jun Lai, MD (23123456, littlecherrytw@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

mean pharyngeal peak pressure (time frame: preoperative, postoperative day 1 and 7). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Oct 2019.
