Study summary

This study is a non invasive study to see if 100% oxygen therapy will help to resolve an intestinal obstruction.

Read the detailed description

TOGA involves the provision of a 6- hour treatment with 100% oxygen via non breather mask to hospitalized patients with ileus, small bowel obstruction and/or colonic pseudo-obstruction will be a useful supplemental therapy, decreasing the diameter of the intestinal lumen and enhancing resolution of ileus/pseudo-obstruction

In context

Ileus

167 studies on the registry are indexed under Ileus; 23 are open to participants now.

This study's enrollment of 17 is below the median of 90 across 138 interventional studies indexed under Ileus.

Inclusion criteria

  • patient or health proxy has been adequately informed of risks and benefits and agrees to his/her participation in the study.
  • patient is a hospitalized inpatient diagnosed with ileus, bowel obstruction or colonic pseudo-obstruction [clinician interpretation or small bowel diameter ≥3.5 cm, cecal diameter ≥ 9 cm, sigmoid colon diameter ≥ 6 cm].
  • patient is clinically and hemodynamically stable
  • patient does not require supplemental oxygen greater than 2 liters per minute via nasal cannula
  • patient does not have any respiratory to 100% oxygen
  • failure to respond to non-surgical/non-endoscopic therapy for at least 24 hours, therapy at discretion of treating physician [to eliminate patients with trivial ileus not requiring advanced intervention]

Exclusion criteria

Exclusion Criteria:

  • patient is not expected to survive in the short term.
  • patient is a pregnant or lactating woman.
  • patient presents with severe or unstable psychiatric disorders.
  • patient is participating in concomitant research studies that would interfere with this study.
  • patient is an alcohol or drug abuser.
  • respirator support required.
  • unable to tolerate 100% oxygen for respiratory reasons or any other reasons.
  • perforation of the viscus.
  • inability to obtain .
  • hypoxemia, as in room air oxygen saturation less than 90%.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Changes in Diameter of Colon

    X-ray of kidney, ureter and bladder (KUB) to determine maximal cecal diameter, maximal mid-transverse colon diameter, maximal mid-sigmoid colon diameter.

    Time frame: 6 - 24 hours

  2. Changes in Diameter of the Small Bowel

    X-ray of kidney, ureter and bladder (KUB) to determine maximal cecal diameter, maximal mid-transverse colon diameter, maximal mid-sigmoid colon diameter.

    Time frame: 6 - 24 hours

Secondary outcomes

  1. Demonstrates No Resolution of Ileus

    A second treatment with TOGA will be offered.

    Time frame: 24 - 30 hours after initial TOGA

  2. Worsening of Ileus

    Worsening of ileus after initial treatment but not requiring surgical or endoscopic intervention, will be offered a second treatment of TOGA.

    Time frame: 24 - 30 hours after initial TOGA

  3. Need for endoscopic or surgical intervention

    Worsening of ileus after initial treatment, requiring surgical or endoscopic intervention

    Time frame: 24 - 30 hours after initial TOGA

  4. Length of Hospital Stay

    Length of stay, measured at the end of hospitalization

    Time frame: up to 100 weeks

  5. Patient Complaints

    Recording of patient perception/tolerance \[daily\] of TOGA.

    Time frame: Up to 48 hours

  6. Patient Pain Measurement

    Patient pain measurement determined subjectively through a visual analogue scale (VAS) scale of 0 (no pain) to 10 (worst pain imaginable) taken before and after TOGA treatment.

    Time frame: Up to 48 hours

  7. Medication Measurement

    Documenting medication requirements for patients exposed to TOGA.(past 24 hours on a scale of 0 (no pain) to 10 (worst pain imaginable)

    Time frame: 24 hours before through 24 hours after TOGA

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 Dec 12, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
