About this study

Official title: A Prospective Trial to Evaluate Whether Variations in Tissue Oxygenation Are Associated With Anastomotic Leak Rates After an Ivor Lewis Esophagectomy

The purpose of this study is to test whether after an Ivor Lewis esophagectomy (the removal of a portion of the stomach and esophagus with re-attachment) there is an association between the intraoperative level of oxygen at the site where the esophagus is re-attached to the stomach (measured using the Wipox), and the incidence of a disruption at the site of the attachment after the surgery.

What participants receive

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

  • wireless pulse oximeter (Wipox)Device

    Also called Post-operatively, all complications will be recorded and graded by the RSA., Anastomotic leaks present either symptomatically or asymptomatically. An, asymptomatic leak is only detected on the routine post-operative esophagram on, post-operative days 5-7, and is isusally described as a 'contained leak'. A

    In addition to the one Wipox measurement at the planned anastomotic site, the RSA will collect the systemic pulse oximeter reading, blood pressure, and heart rate at the time of the Wipox measurement. These measurements will be obtained as both internal controls of the accuracy of the Wipox (matching the Wipox pulse rate with the patient's), as well as additional variables to control for when assessing factors which might contribute to oxygen saturation at the anastomotic site. Pre-operative demographic information will be collected. This will include age, sex, any co-morbidities (cardiac, diabetes, respiratory), and use of pre-operative chemotherapy or chemo-radiotherapy.

Study groupRoleWhat they receive
Pts scheduled for Ivor Lewis esophagectomyDuring the operation, once the gastric conduit has been mobilized and positioned, and once the anastomotic site has been identified by the surgeon, the assigned RSA will provide the Wipox instrument to the fellow (the primary surgeon will be blinded to the result) who will then obtain one measurement from the anastomotic site.
Receives: Device: wireless pulse oximeter (Wipox)

What is being measured

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

  1. association between tissue oxygenation (measured using the Wipox) at the anastomotic site and the incidence of anastomotic leak after an Ivor Lewis esophagectomy.

    The primary objective of this observational study is to determine whether in patients undergoing Ivor Lewis esophagectomy, low levels of tissue oxygenation at the anastomotic site are associated with increased risk of anastomotic leak (AL).

    Measured: 2 years

Secondary outcomes (3)
  1. To correlate various demographic

    (age, co-morbidities, smoking history) and clinical variables (pre-operative therapy, intra-operative blood pressure and systemic oxygen saturation) with tissue oxygenation at the anastomotic site. Spearman rank correlation (for continuous variables) and Wilcoxon rank sum test (for categorical variables) will be used to test these associations.

    Measured: 2 years

  2. To correlate anastomotic site tissue oxygenation with the postdischarge incidence of stricture

    the association between anastomotic site tissue oxygenation and the incidence of post-discharge stricture observed during the 6 months following surgery will be assessed using Wilcoxon rank sum test (with O2 levels on a continuous scale) and Fisher exact test.

    Measured: 2 years

  3. To correlate clinical variables

    (age, co-morbidities, smoking history) and clinical variables (pre-operative therapy, intra-operative blood pressure and systemic oxygen saturation) with tissue oxygenation at the anastomotic site. Spearman rank correlation (for continuous variables) and Wilcoxon rank sum test (for categorical variables) will be used to test these associations.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Esophageal Cancer, run by Memorial Sloan Kettering Cancer Center at 1 site in United States.

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 1 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: finished, as of the sponsor's last update on 18 Aug 2016. 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 United States. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

association between tissue oxygenation (measured using the Wipox) at the anastomotic site and the incidence of anastomotic leak after an Ivor Lewis esophagectomy. (time frame: 2 years). 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 18 Aug 2016.
