Study summary

This feasibility study is for the purpose of determining if the G-Tech Device can differentiate between normal return of GI activity post-operatively and the myoelectric activity in patients who develop a POI.

Read the detailed description

While preventing the development of a POI is most important, POIs still occur; therefore, it is important to definitively diagnose a POI as early as possible during the post-operative course for treatment to prevent patient discomfort, complications, and extended hospital stay. The purpose of the G-Tech study is to determine if the G-Tech Device can detect a difference in the myoelectric signals from patients who develop a POI compared to those patients who do not develop a POI. It is anticipated that up to 20% of patients enrolled in this study and consented preoperatively, excluding screen failures, will show evidence of a post-operative ileus as detected by the G-Tech GutCheck Device and differentiate the myoelectric signals from the patients who do not develop a POI. Patients who are known to have developed a POI may also be selected for the study.

Study population

The study population will include candidates who undergo GI surgery or other surgery outside not involving the abdominal cavity, who agree to the application of the G-Tech Device to be placed on his/her abdomen and meet all eligibility criteria as defined. Up to 100 subjects may be consented prior to surgery who are planned to undergo gastrointestinal surgery or a planned surgery that does not involve the abdominal cavity or following. Up to 50 subjects who have undergone gastrointestinal surgery or surgery not involving the abdominal cavity may be consented post-operatively during their hospital stay for this study.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Willing and able to provide ;
  2. Eighteen (18) years of age or older;
  3. Subject is willing and able to follow all study requirements;
  4. Subject who will undergo or has undergone open or laparoscopic gastrointestinal surgery or surgery not involving the abdominal cavity.

Exclusion criteria

Exclusion Criteria:

  1. Subject is pregnant or suspects pregnancy;
  2. Known allergy to medical grade adhesive;
  3. Weight > 350 lbs (159 Kg);
Terms in these criteria, in plain language(1)

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.

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.

Groups and cohorts

  • Subjects with unknown POI status consented pre-surgery

    Up to 100 subjects may be consented prior to surgery who are planned to undergo gastrointestinal surgery or a planned surgery that does not involve the abdominal cavity. The investigator does not change the routine medical care of study participants.

    Device: G-Tech Myoelectric recording device

  • Subjects with known/unknown POI status consented post-surgery

    Up to 50 subjects who have undergone gastrointestinal surgery or surgery not involving the abdominal cavity may be consented post- operatively during their hospital stay for this study.The investigator does not change the routine medical care of study participants.

    Device: G-Tech Myoelectric recording device

Interventions

  • DeviceG-Tech Myoelectric recording device

    A minimum of three patches are placed on the abdomen of the patient to record myoelectric activity.

    Also known as: Gastro-intestinal electrical recording

What researchers measure

Primary outcomes

  1. Myoelectric activity pattern in POI patients versus non-POI patients

    The resumption of motor activity in the stomach, small intestine, and colon post-operatively. The measurement is myoelectric signals measured at the skin surface similar to ECG recordings for the heart

    Time frame: Up to 6 Days

Secondary outcomes

  1. Anticipated Adverse Events

    Device related anticipated adverse events; such as, skin irritation due to adhesive from the skin patch.

    Time frame: Up to 6 days

  2. UADEs

    Unanticipated adverse device effects

    Time frame: Up to 6 Days

  3. Device Success

    Device success defined as the ability to record GI myoelectric activity following GI surgery.

    Time frame: Up to 6 Days

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 Jan 20, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
