The extensive research you carried out was on acute pancreatitis that’s unrelated to gallstones. Please could you explain the reason for only focussing upon this rather than including acute pancreatitis that’s linked to gallstones? There are two main reasons. Firstly, the large part of patients with acute pancreatitis that is classified as idiopathic pancreatitis. Secondly, the known fact that just a minority of chronic alcohol abusers develops acute pancreatitis. Gallstones also induce acute pancreatitis by mechanical obstruction of the bile duct and/or the pancreatic duct . This mechanical obstruction isn’t the case for additional proposed causes of acute pancreatitis.All privileges reserved.
