pancreatic fistula/protease

BACKGROUND Ischaemia and local protease activation close to the pancreaticojejunal anastomosis (PJA) are potential mechanisms of postoperative pancreatic fistula (POPF) formation. To provide information on the pathophysiology of POPF, intraperitoneal microdialysis was used to monitor metabolic

Objectives: Postoperative pancreatic fistula (POPF) subsequent to pancreatectomy often causes activation of pancreatic juice, resulting in serious complications. In POPF, the types of pancreatic juices found are active and inactive, and

BACKGROUND Pancreatic duct cells (PDCs) are responsible for bicarbonate production by the pancreas. The trypsin-sensitive protease-activated receptor (PAR-2), also known as the trypsin receptor, is highly expressed in the pancreatic duct system and has been shown to regulate PDC ion transport. The

Postoperative pancreatic fistula (POPF) is the most serious and challenging complication following gastroenterological surgery. Activated pancreatic juice leaking from the organ remnant contains proteases that attack the surrounding tissue, potentially leading to severe inflammation, tissue

Although older work indicated that luminal peptides are stimulants of pancreatic secretion, these earlier experiments were performed with crude peptide mixtures containing amino acids that are also known stimulants. Furthermore, no information was provided about size or composition of stimulating

BACKGROUND Pancreatic fistula after pancreatoduodenectomy (PD) is associated with high mortality and morbidity. Trypsinogen activation and bacteria, although hypothesized to be interrelated etiopathogenetically, have not had their relationship and pathogenic mechanisms elucidated. This study

Pancreatic secretion in rats is regulated by feedback inhibition of cholecystokinin (CCK) release by proteases in the gut lumen, but little is known about the role of gastric acid in this regulation. This study, carried out on conscious rats with large gastric fistulas (GF) and pancreatic fistulas,

BACKGROUND Pancreatic fistula (PF) remains the most serious complication after digestive surgery. It is difficult to prevent because of the inability to visualize the leakage of pancreatic juice during surgery or to evaluate the protease activity of leaked fluid, which is responsible for PF

Pancreatic bicarbonate and protein secretory responses to intestinally perfused proteins or digests of proteins were measured in dogs with chronic gastric and pancreatic fistulas when luminalpancreatic protease concentrations were reduced to undetectable levels. Protein digests were analyzed for

Pancreaticoduodenectomy (Whipple's procedure) represents a considerable surgical challenge. Postoperative complications are common and typically related to leakage of pancreatic exocrine secretions following anastomosis failure. Pancreatic proteases and lipase leaking from the organ remnant attack
