K85.1

Clinical Causes: Presence of gallstones that obstruct the pancreatic duct Blockage of the pancreatic duct by gallstones entering the bile duct and obstructing the flow Migration of gallstones from the gallbladder into the common bile duct Inflammation caused by bile reflux into the pancreas Other contributing factors may include high triglyceride levels, alcohol use, or certain medications, but these are less common in biliary pancreatitis

Key Symptoms: Sudden, severe abdominal pain that may radiate to the back Nausea and vomiting Tenderness in the upper abdomen Bluish discoloration around the navel or the sides (Cullen's sign or Grey Turner's sign) Fever or chills indicating possible infection Elevated heart rate and low blood pressure in severe cases Jaundice (yellowing of the skin and eyes) in cases where bile duct obstruction is significant

Diagnosis Path: Physical examination to identify abdominal tenderness or signs of complications Blood tests to check for elevated levels of amylase and lipase enzymes, indicative of pancreatic inflammation Liver function tests to assess bile flow and detect jaundice Imaging studies such as abdominal ultrasound to visualize gallstones and pancreatic swelling CT scan or MRCP (Magnetic Resonance Cholangiopancreatography) for detailed imaging of the pancreas and bile ducts Endoscopic procedures like ERCP (Endoscopic Retrograde Cholangiopancreatography) to locate and sometimes remove gallstones

Treatment Protocols: Hospitalization for close monitoring and management Pain management using medications to relieve severe abdominal pain Fasting or dietary restrictions to rest the pancreas IV fluids to prevent dehydration and support organ function Antibiotics if an infection is suspected Procedures such as ERCP to remove gallstones obstructing the bile or pancreatic ducts Surgical removal of the gallbladder (cholecystectomy) to prevent further stone formation Management of underlying causes like high triglycerides or other contributing conditions
