Utility of Trypsinogen -2 in Early Detection and Follow Up of Post-pancreatectomy Acute Pancreatitis (PPAP)

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.
