Acquired obstructive forms typically result from blunt abdominal trauma or accidents involving motor vehicles, bicycles, horses, or, on occasion, severe falls. In these cases, the pancreas is whiplashed against the spine, causing trauma to the ductal system, resulting in a stricture close to the surgical genu. In rare instances, chronic inflammatory conditions affecting the duodenum, or primarily the duodenal papilla, can induce fibrosis and papillary stenosis in a subset of patients, leading to chronic pancreatitis.
