NCT02673671

Brief 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.

Outcome Measures

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

    Up to 6 Days

Secondary Outcomes (3)

  • Anticipated Adverse Events

    Up to 6 days

  • UADEs

    Up to 6 Days

  • Device Success

    Up to 6 Days

Study Arms (2)

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

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

Also known as: Gastro-intestinal electrical recording
Subjects with known/unknown POI status consented post-surgerySubjects with unknown POI status consented pre-surgery

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
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.

You may qualify if:

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

You may not qualify if:

  • Subject is pregnant or suspects pregnancy;
  • Known allergy to medical grade adhesive;
  • Weight \> 350 lbs (159 Kg);
