The aim of our study is to evaluate S-MRCP, in comparison to direct pancreatic function, to measure pancreatic exocrine function in patients who have symptoms suspicious for insufficiency. We hypothesize that S-MRCP imaging parameters will correlate well with the direct pancreatic exocrine functioning.
Surgical resection offers the only hope of cure for pancreatic adenocarcinoma. While perioperative mortality rates have declined in recent years, pancreatic resection is still associated with significant postoperative malnutrition, maldigestion, and glucose intolerance, mostly as a result of pancreatic insufficiency. Quantifying individual pancreatic function remains a challenge, but is essential in improving the survival and quality of life of pancreatic cancer patients. Secretin-enhanced magnetic resonance cholangiopancreatography (S-MRCP) has recently emerged as a widely-accepted noninvasive technique to assess morphological changes in pancreatic ducts, as well as functional secretory capacity of the gland. The aim of our study is to evaluate S-MRCP as a means to evaluate for pancreatic exocrine insufficiency. This will be a prospective study of twelve patients who have undergone pancreatic resection and who have symptoms of abdominal pain, steatorrhea or weight loss. We will be comparing quantitative parameters of S-MRCP (maximal change in pancreatic duct diameter and volume before and after secretin administration) with endoscopic pancreatic function testing (maximal bicarbonate concentration in duodenal aspirate after secretin administration).

A peptide hormone of about 27 amino acids from the duodenal mucosa that activates pancreatic secretion and lowers the blood sugar level. (USAN and the USP Dictionary of Drug Names, 1994, p597)
Gram-negative bacterial secretion systems which carry out the secretion of folded proteins.T2SSs secrete folded proteins from the PERIPLASMIC SPACE that have been exported there by SEC TRANSLOCASE or TAT SECRETION SYSTEMS, or they secrete folded proteins directly from the CYTOPLASM. The T2SSs have four substructures, an ATPase, an inner membrane platform, a pseudopilin, and secretin, an outer membrane complex which is a channel for secretion. (This bacterial secretin is not the same as the mammalian hormone also named SECRETIN.)
C-type lectins that restrict growth of bacteria in the intestinal epithelia and have bactericidal activity against gram-positive and gram-negative bacteria. They also regulate proliferation and differentiation of KERATINOCYTES following injury. Human pancreatitis-associated protein-1 (Reg3a) is overexpressed by pancreatic ACINAR CELLS in patients with CHRONIC PANCREATITIS. It is also highly expressed by pancreatic, bladder, and gastrointestinal cancer cells and may serve as a diagnostic biomarker.
Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).
Star-shaped, myofibroblast-like cells located in the periacinar, perivascular, and periductal regions of the EXOCRINE PANCREAS. They play a key role in the pathobiology of FIBROSIS; PANCREATITIS; and PANCREATIC CANCER.
