Endoscopic retrograde cholangiopancreatography (ERCP), together with its substantial therapeutic capabilities, carries a higher potential for complications than other endoscopic procedures. Common major complications specific to pancreaticobiliary instrumentation include pancreatitis, post-sphincterotomy hemorrhage, perforation, and cholangitis with or without systemic sepsis. Two patients underwent therapeutic ERCP for recurrent episodes of abdominal pain and elevation of hepatobiliary enzymes. Endoscopic sphincterotomy was difficult and prolonged. The calculi were successfully extracted by sweeping the choledochus with a balloon-tipped catheter or basket in both cases. The patients experienced postprocedure diffuse abdominal pain unassociated with nausea or vomiting. Laboratory data showed normal serum amylase and lipase 2, 6, and 18 h after the end of procedure, a fall in hematocrit level, and an increase of indirect bilirubin and lactic dehydrogenase. The abdominal pain subsided in 4 to 6 h. The hematocrit level remained stable during the next 3 days, and the patients were very well when discharged. Examination of glucose-6-phosphate dehydrogenase (G-6PD) enzyme levels in red cells 20 days later showed complete enzyme deficiency. This report highlights the importance of examining G-6PD deficiency in patients with post-ERCP abdominal pain, normal serum amylase and lipase, and laboratory findings of hemolysis.
