Trial summary

Esophageal surgery is a complex surgery, with high post-operative morbidity and mortality. The incidence of complications associated with esophagectomy varies from 17% to 74%, in the literature. A section of vagus nerves is conventionally performed during esophagectomy for cancer, because of oncological margins. Read more about this study

About this study

Official title: Prospective Monocentric Evaluation of the Autonomic Nervous System in Patients Undergoing Esophagectomy for Cancer

Esophageal surgery is a complex surgery, with high post-operative morbidity and mortality. The incidence of complications associated with esophagectomy varies from 17% to 74%, in the literature. A section of vagus nerves is conventionally performed during esophagectomy for cancer, because of oncological margins. The vagus nerve is responsible for the parasympathetic innervation at the gastrointestinal level, but also at the cardiac and pulmonary level. The post-operative morbidity of these procedures could be linked in part to the bilateral section of the vagus nerves, because of their impact on the autonomous regulation of this vital functions. The main objective of the study is to find a modification of the sympathomimetic balance pre and post operatively, in patients undergoing esophagectomy.

Read the detailed description

The sympathomimetic balance was measured using a Holter-ECG heart rate monitor. The parameters collected were used to calculate the variability of the heart rate, the high frequencies (HF, reflection of the parasympathetic system), the low frequencies (LF, reflection of the sympathetic system and the parasympathetic system) and the ratio // LF / HF (reflection of the sympathetic activity) thanks to Fourier analysis and the use of HRVanalysis software.

The measurements were taken at night, to overcome the great sympathomimetic variabilities due to external stimulations during the day: one night 3 month before surgery/before the first chemotherapy, one night between 2 and 4 weeks before hospitalization (remotely of possible chemotherapy), the night before the intervention (context of hospitalization and preoperative stress), one night between D7 and D10 (context of hospitalization, and distance from anesthetic drugs), one night at home between 4 and 8 weeks post-operative, and one night at home at 3 months post-operative.

The measurements were therefore not carried out the first nights following the intervention to overcome the anesthetic drugs that affect the balance of the autonomic nervous system.

A baroreflex measurement was carried out at the patient's entrance, the day before the intervention, during hospitalization, and the day of discharge. This measure was renewed at 3 months.

A measurement of patient activity was carried out preoperatively by wearing an actimeter watch for 1 week then renewed at 3 months.

A Respiratory Functional Exploration associated with a stress test with calculation of the VO2max is systematically carried out before the esophageal surgery. A Respiratory Functional Exploration was renewed 4 to 8 weeks after the intervention, and then at 3 months. the 6-minute walk test was performed at the same time.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Holter ECGDiagnostic test

    Measurement of the modification of the sympathomimetic balance

  • QuestionaryBehavioural

    Lifestyle questionary (time spent in front of television, physical activity)

  • PupillometryDiagnostic test

    Monitoring of nociception and autonomic nervous system by pupillometry in intraoperative.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Analysis of Standard deviation of all NN (SDNN) (ms)

    Analysis of Standard deviation of all NN (SDNN) intervals, over the entire registration period, provides information on global variability. Measured by Holter results. Day 0 = surgery

    Measured: before surgery

  2. Analysis of Standard deviation of all NN (SDNN) (ms)

    Analysis of Standard deviation of all NN (SDNN) intervals, over the entire registration period, provides information on global variability. Measured by Holter results. Day 0 = surgery

    Measured: day 7 to day 90

Secondary outcomes (10)
  1. HF activity

    Day 0 = surgery measured with the Holter Electrocardiogram

    Measured: before surgery : Day -82, Day -30, Day -1

  2. LF activity

    Day 0 = surgery measured with the Holter Electrocardiogram

    Measured: before surgery : Day -82, Day -30, Day -1

  3. LF/HF ratio

    Day 0 = surgery measured with the Holter Electrocardiogram

    Measured: before surgery : Day -82, Day -30, Day -1

  4. HF activity

    Day 0 = surgery measured with the Holter Electrocardiogram

    Measured: after surgery : day 7, day 60, day 90

  5. LF activity

    Day 0 = surgery measured with the Holter Electrocardiogram

    Measured: after surgery : day 7, day 60, day 90

  6. LF/HF ratio

    Day 0 = surgery measured with the Holter Electrocardiogram

    Measured: after surgery : day 7, day 60, day 90

  7. change in baroreflex

    baroreflex sensitivity : ms/mmHg Day 0 = surgery

    Measured: Day -1, Day 7, day discharge, day 90

  8. modify the respiratory functional exploration

    Peak expiratory volume per second : L Day 0 = surgery

    Measured: Day -30, Day 30, Day 60

  9. intraoperative pupillometry

    pupillary diameter : mm

    Measured: during surgery

  10. physical capacity

    walking distance in 6 minutes Day 0 = surgery

    Measured: Day-30, Day 30, Day 90

Questions about this trial

What is this clinical trial studying?

An observational study of Esophageal Cancer, run by Centre Hospitalier Universitaire de Saint Etienne at 1 site in France.

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 2 inclusion and 4 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: withdrawn, as of the sponsor's last update on 24 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

The study was withdrawn before enrolling participants, so there are no results.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Analysis of Standard deviation of all NN (SDNN) (ms) (time frame: before surgery). The study lists 2 primary outcomes in all. 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 24 Nov 2023.
