ARTICLE HIGHLIGHTS
Research background

Splanchnic vein thrombosis (SVT) is a severe complication of acute pancreatitis that may cause portal hypertensive complications and bowel ischemia. To prevent such complications, therapeutic anticoagulation is recommended in the general population of patients with an acute SVT.

Research motivation

Evidence to support this recommendation in acute pancreatitis patients does however not exist and as a result, clinical decision-making is mostly based on the preferences and beliefs of the pancreatologists.

Research objectives

To gain insight into current opinions on the use of therapeutic anticoagulation for SVT in acute pancreatitis.

Research methods

An online survey was sent to 139 Dutch pancreatologists. The threshold to assume agreement was set at 75%.

Research results

The response rate was 67% (n = 93). Seventy-one pancreatologists (77%) regularly prescribed therapeutic anticoagulation for SVT, using LMWH in the acute phase (87%). The majority favored therapeutic anticoagulation for acute thrombosis (90%), portal vein thrombosis in patients with or without infected necrosis (82% and 90%) and in case of thrombus progression (88%). There was no agreement whether the risk of bleeding is a barrier for initiation of therapeutic anticoagulation.

Research conclusions

The pancreatologists reached agreement regarding the use of therapeutic anticoagulation for SVT, particularly in cases of acute thrombosis, portal vein thrombosis and thrombus progression.

Research perspectives

To get a better understanding of the therapeutic role of anticoagulation, it is crucial to conduct prospective studies targeting the pathophysiology and natural course of SVT in acute pancreatitis patients.
