Marathon pancreatitis: a case of acute pancreatitis caused by distance running.

ABSTRACT

Marathon running or other forms of strenuous exercise have been reported as a rare cause of acute pancreatitis. Theories as to the mechanism of acute pancreatitis include microvascular ischaemia due to dehydration or repetitive trauma to the pancreas. We report a case of a healthy woman in her 30s who developed abdominal pain, nausea and vomiting after a 32 km marathon training run. She was found to have elevated lipase and inflammation of the pancreatic tail with associated pericolic and pelvic free fluid on CT scan. Workup including abdominal ultrasound and magnetic resonance cholangiopancreatography (MRCP) did not reveal biliary or pancreatic duct pathology. She improved with conservative management. These findings support the hypothesis of exercise-induced pancreatitis from long-distance running.
