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.

Condition or disease Intervention/treatment
Post-operative Ileus Device: G-Tech Myoelectric recording device

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.

Group/Cohort Intervention/treatment
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
A minimum of three patches are placed on the abdomen of the patient to record myoelectric activity.
Other Name: Gastro-intestinal electrical recording
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
A minimum of three patches are placed on the abdomen of the patient to record myoelectric activity.
Other Name: Gastro-intestinal electrical recording


Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Myoelectric activity pattern in POI patients versus non-POI patients [ Time Frame: Up to 6 Days ]
    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


Secondary Outcome Measures :
  1. Anticipated Adverse Events [ Time Frame: Up to 6 days ]
    Device related anticipated adverse events; such as, skin irritation due to adhesive from the skin patch.

  2. UADEs [ Time Frame: Up to 6 Days ]
    Unanticipated adverse device effects

  3. Device Success [ Time Frame: Up to 6 Days ]
    Device success defined as the ability to record GI myoelectric activity following GI surgery.
