Brief description of study

The goal of this study is to learn if urine trypsinogen can be used to diagnose post-pancreatectomy acute pancreatitis in patients undergoing pancreatectomy. Participants will have their urine measured by dipsticks during and after their surgery.

Patients will be recruited from the patient group undergoing pancreatectomy at IU University hospital. These patient's will be prospectively identified by reviewing the schedule of Dr. Nicholas Zyromski. All patients undergoing pancreatectomy will be offered the chance to enroll in the study. Patients will not be specifically selected for or against. These patients will be contacted the morning of their surgery at University hospital in the pre-Operative area. A discussion of the goals of the project, what it entails for the patients, and any risks for the patient will be completed.

THIS STUDY IS ENROLLING BY INVITATION ONLY - Consistent with most oncology trials, patients are not actively “recruited,” but are screened by their physician for appropriate clinical trial(s) at the time of their routine clinic visit. Occasionally, a patient may be a self-referral or physician referral, but are still screened for appropriate clinical trials at the time of their routine clinic visit. PI and staff may send copies of relevant consent forms to these patients to look over prior to actually consenting or enrolling them. This may take place at the patient's visit at which the consent is presented or the patient's next visit to the outpatient hematology/oncology clinic.

Detailed description of study

Patients will be identified utilizing preoperative scheduling and clinic visits. Patients undergoing any pancreatectomy (such as: pancreatoduodenectomy, distal pancreatectomy, duodenal preserving pancreatic head resection) will be identified. These patients will be educated about possible enrollment in the prospective study in the preoperative clinic or in the surgery preoperative area. If enrolled, these patients will receive the standard of care postoperative laboratory tests. These include, but are not limited to, postoperative serum amylase, drain amylase, complete blood counts, and complete or basic metabolic panels. These patients will have standard of care pathologic review of their operative specimens. These patients will also have their urine tested for TRP-2. This design will allow for the direct comparison of the TRP-2 dipstick tests against the standard of care serum amylase tests. Furthermore, the measuring of serum amylase will allow for the evaluation of post-pancreatectomy acute pancreatitis by the ISGPS definition.

Eligibility of study

You may be eligible for this study if you meet the following criteria:

  • Conditions: Pancreatectomy, Pancreatitis, Post-Pancreatectomy Acute Pancreatitis, PPAP
  • Age: 18 years - 100 years
  • Gender: All

Inclusion Criteria:

  • Older than 18 years of age
  • Undergoing elective pancreatectomy for any indication

Exclusion Criteria:

  • Younger than 18 years of age
  • Pregnant women
  • Prisoner

This study investigates the use of urinary trypsinogen-2 to detect post-pancreatectomy acute pancreatitis (PPAP). Pancreatectomy is a surgery to remove part or all of the pancreas. PPAP is a condition that can occur after this surgery, where the pancreas becomes inflamed. The purpose of this study is to see if measuring trypsinogen-2 in urine can help identify PPAP early, allowing for better monitoring and care of patients after their surgery.

Participants will have their urine tested for trypsinogen-2 during and after their surgery. Trypsinogen-2 is a substance that can be measured to see if the pancreas is inflamed. The study will compare these test results with other methods of diagnosing PPAP to see how well they agree.

  • Who can participate: Adults over 18 years old who are having a planned pancreatectomy can participate. Pregnant women are not eligible.
  • Study details: Participants will have urine samples collected during their surgery to measure trypsinogen-2 levels. This is to see if it can detect pancreatitis early. The study will also compare these results with other diagnosis methods.
