Study 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. 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 researchers measure

Primary outcomes

  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

    Time frame: 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

    Time frame: day 7 to day 90

Secondary outcomes

  1. HF activity

    Day 0 = surgery measured with the Holter Electrocardiogram

    Time frame: before surgery : Day -82, Day -30, Day -1

  2. LF activity

    Day 0 = surgery measured with the Holter Electrocardiogram

    Time frame: before surgery : Day -82, Day -30, Day -1

  3. LF/HF ratio

    Day 0 = surgery measured with the Holter Electrocardiogram

    Time frame: before surgery : Day -82, Day -30, Day -1

  4. HF activity

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 24, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
