Effects of Early Stage Mini-invasive Abdominal Drainage on Complications and Prognosis of SAP
Effects of Early Stage Mini-invasive Abdominal Drainage on Complications and Prognosis of SAP
This study aims to standardized the process of mini-invasive abdominal draniage of SAP in
 early stage.To determine the indications and occasion.
Pancreatitis associated ascetic fluids(PAAF) gather with the beginning of SAP and induced
 IAP(intra-abdominal pressure) increasement.With an excess of 12mmHg ,IAP presents as
 IAH(intra-abdominal hypertension) and when a ≥20mmHg IAP accompanied with at least one
 organ's dysfunction it is ACS(abdominal compartment syndrome).Previous recommended theraphy
 of ACS is laparotomy.However,with inherited advantages such as ease-to-operate and minimal
 invassiveness, early stage mini-invasive abdominal drainage therapies , for example,
 percutaneous catheter drainage(PCD) instructed by ultrasound or CT ,have shown a promised
 future in recent years. It is reported that patients acquired PCD decreased 81% in operation
 rate compared to those who did not and had lower mortality rate. Whereas, the operation flow
 of early stage mini-invasive abdominal drainage remains controversial, and whose validity
 calls for evidence from large-scale clinical trials.
