Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this study, the investigators aim to distinguish patients with Post-Endoscopic retrograde cholangiopancreatography (ERCP) Pancreatitis (PEP) vs. those without PEP based on difference in pre- vs. post-ERCP measurements of AGIS-derived intestinal rates (IR). Based on the clinical observation that many patients with PEP develop ileus following ERCP, the investigators hypothesize that patients who develop PEP will exhibit lower IR following ERCP, and therefore a larger difference in pre- vs. post-ERCP IR.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This will be a prospective case series in 100 patients presenting to Cedars Sinai Medical Center who undergo Endoscopic retrograde cholangiopancreatography (ERCP).

The investigators will place the AGIS sensor on each patient enrolled in the study, 30 minutes prior to procedure. The investigators will continuously record AGIS acoustic signals from T-30 minutes to the time that they leave the hospital, either on discharge from the Post-Anesthesia Care Unit or discharge from hospitalization, with the option to discontinue if clinically required or requested by the provider or patient. Acoustic signal will be evaluated, and intestinal motility events will be calculated; however, this data will not be used to make decisions regarding clinical care. Physicians and nurses will not be made aware of the AbStats readings.These measurements are solely observational. Patients will be managed according to standard-of-care practice.

Routinely, patients are kept in the post-operative unit after their procedure, for one hour. Those with pain are examined by a physician and the decision is made to admit for observation to monitor for complications of ERCP, or to discharge home. The patients who are discharged home from procedure will be followed by telephone surveys every day for 2 days post procedure to determine if they have developed symptoms suggestive of PEP. If so, they will be asked to go to the closest urgent care or emergency department for further evaluation. Those who are admitted for observations post procedure will be followed for signs or symptoms of PEP which includes meeting 2 of 3 criteria: Abdominal pain, amylase/lipase \>3 times the upper limit of normal 24 hours after procedure, and/or imaging consistent with pancreatitis.

The AGIS multi-sensor wireless abdominal monitoring system includes low profile acoustic sensors that are applied to the anterior abdominal wall with Tegaderm and monitors sounds emanating from the GI tract. The acoustic sensors continuously and non-invasively monitor and capture audio signals representing GI and abdominal wall function. The captured data is recorded in a synchronized manner from two sensors, each placed 3cm on either side of the umbilicus.

After a patient's participation in the study is complete, the investigators will analyze the AbStats readings and the their clinical outcomes to observe if correlations exist between patients with lower intestinal rates and those who develop PEP.
