Fecal Microbiota Transplantation (FMT) for Severe Acute Pancreatitis(SAP)

Alteration of Intestinal Microflora and Efficacy and Safety of Fecal Microbiota Transplantation for Severe Acute Pancreatitis

Severe acute pancreatitis is an acute and rapid progress of the digestive system disease.Most patients with severe pancreatitis associated with intestinal mucosal barrier dysfunction.Intestinal microflora,an important part of the intestinal mucosal barrier, play an important role in the development process in the course of severe acute pancreatitis. At this stage of the study that infection of pancreas and other organs is the leading cause of death in patients with severe acute pancreatitis，and the main pathogens from intestinal micro-organisms， but the intestinal flora changes did not be mentioned. Fecal Microbiota Transplantation that has been used for treatment of inflammatory bowel disease and Clostridium difficile infection may be a new technology for regulation of intestinal mucosal dysfunction and intestinal flora unbalance.

Patients with acute pancreatitis will be assessed depending on APACHE II and CT score and all of them also will be separated into two parts depending on acceptation or refusal of FMT. Blood specimens from patients will be collected to analysis inflammatory factors，and fecal microbiota samples will be detection.
