Incomplete resection of choledochal cysts (CCs) that extend deep into the pancreas can lead to protein plug or stone formation, pancreatitis, and cholangiocarcinoma. We encountered two cases of choledocholithiasis in remnant intrapancreatic CCs, in which the patients exhibited symptoms after 3 and 21 years of cyst excision. A 21-year-old woman who had undergone excision of a CC, as a neonate, p...

A 49-year-old man with a history of acute pancreatitis was hospitalized with a diagnosis of pancreatic pseudocyst. Ultrasonography, computed tomography, and magnetic resonance imaging all demonstrated a homogeneous cyst, 9 x 4 cm in size, at the tail of the pancreas without mural nodules or septa. Because an intestinal structure was identified between the cyst and stomach preoperatively by comp...

The aim of this study was to present a case of enteric duplication cyst and criteria for a proper differential diagnosis. A 51-year-old male was hospitalized for pancreatic tail neoplasm and distal pancreatectomy with splenectomy was performed. During surgery, a jejunal cystic lesion was incidentally detected and jejunectomy was performed. Microscopically, the cyst was observed to be covered by...

CONTEXT Choledochal cysts, rarely present with chronic calcific pancreatitis. We report two patients with choledochal cysts who had concomitant chronic pancreatitis. CASE REPORT #1: A 27-year-old female with a history of recurrent abdominal pain, fever and jaundice presented with a type I choledochal cyst with calcifications in the uncinate process of the pancreas on CT scan. Her magnetic reson...

PURPOSE Pancreatic cysts frequently pose clinical dilemmas. On one hand, cysts with high-grade dysplasia offer opportunities for cure, on the other hand, those with low-grade dysplasia are easily over treated. Cyst fluid markers have the potential to improve the evaluation of these cysts. Because telomerase activity is commonly activated in malignant cells, we evaluated the diagnostic performan...

BACKGROUND This study was performed to evaluate the utility of serum and cyst fluid analysis for enzymes (amylase and lipase) and tumor markers (carcinoembryonic antigen, CA 19-9, CA 125, and CA 72-4) in the differential diagnosis of cystic pancreatic lesions. METHODS Serum and cyst fluid were obtained from 48 patients with pancreatic cysts (21 pseudocysts, 14 mucinous cystic neoplasms, 6 duc...
