Context: Endoscopic ultrasonography guided fine needle aspiration (EUS-FNA) is a front line test used for the diagnosis of solid as well as cystic lesions of the pancreas. This procedure is fairly well tolerated and associated with minimal complications. Local complications such as perforation and pancreatitis have been reported with EUS-FNA, albeit rarely. Although pancreatic duct injury can occur during EUS-FNA, symptomatic pancreatic duct leak as a complication of this procedure has never been reported., Case Report: We present a 67-year-old patient who developed symptomatic ascites after EUS-FNA of a pancreatic neck lesion that required several paracenteses. Analysis of the ascitic fluid revealed that the fluid amylase and lipase levels were very high consistent with pancreatic ascites. An endoscopic retrograde pancreatography was subsequently performed that documented the presence of a pancreatic duct leak in the neck. The pancreatic duct leak and the ascites resolved after placing a pancreatic duct stent., Conclusion: A clinically significant pancreatic leak can occur as a rare complication of EUS-FNA that can be effectively managed by endoscopic retrograde pancreatography and placement of a transpapillary pancreatic duct stent.

Context: Atypical antipsychotic agents are associated with diabetes mellitus and pancreatitis. Aripiprazole, a new antipsychotic, has never been implicated to cause either diabetes mellitus or pancreatitis. We present a patient who developed diabetes mellitus after being started on aripiprazole., Case Report: A 33 year-old male with schizophrenia presented with fatigue, dyspepsia and epigastric pain. Patient was found to have hyperglycemia, diabetic ketoacidosis, and hyperlipasemia. Imaging studies of the pancreas were normal. Patient was started on aripiprazole treatment 18 months prior to this episode and had experienced progressive weight gain since then. Work up for other causes of pancreatitis was negative., Conclusions: Diabetes mellitus in this patient was probably a complication of aripiprazole due to progressive weight gain. In the absence of radiologic evidence of pancreatitis, hyperlipasemia was probably secondary to diabetic ketoacidosis. Possible causes of hyperlipasemia and its significance in diabetic ketoacidosis are discussed.
