[Postpartum idiopathic acute pancreatitis: diagnostic difficulties (case report)].

Acute pancreatitis during the postpartum period or during pregnancy is rare. Biliary disease is the most common cause of acute pancreatitis, followed by hypertriglyceridemia. We here report the case of a 19-year-old patient with acute pancreatitis occurring 4 weeks after delivery and revealed by epigastralgia radiating to the back, lipasemia more than 36 times the normal limit and etiologic investigation that gave negative results. Early diagnosis of acute pancreatitis during the postpartum period is a challenge for clinicians because it is rare and differential diagnosis includes multiple disorders.
