ABSTRACT
Although arteriovenous malformations (AVM) occur frequently in digestive organs, pancreatic AVM is rare. The clinical symptoms of pancreatic AVM are variable and include gastrointestinal bleeding, abdominal pain, jaundice, portal hypertension, pancreatitis, and duodenal ulcer. However, choledochoduodenal or pancreaticoduodenal fistulas complicated with ascending infection and pancreatitis is extremely rare. Herein, we report a case of pancreaticoduodenal fistula associated with a pancreatic AVM that induced recurrent anemia and ascending infection.

Primary pancreatic lymphoma (PPL) is a rare form of extranodal lymphoma, and this accounts for less than 0.5% of all pancreatic tumors. Differentiating PPL from pancreatic adenocarcinoma is important because the prognosis and survival of PPL is much better than those of pancreatic adenocarcinoma. Although the treatment usually consists of a combination of chemotherapy and radiation therapy, PPL patient with biliary tract or gastrointestinal obstruction should undergo biliary or gastric bypass to relieve the symptoms. Herein, we describe a case of PPL with acute pancreatitis and obstructive jaundice, and the patient was successfully managed with endoscopic retrograde pancreatic and biliary drainage.

Primary neuroendocrine carcinoma of the gallbladder is extremely rare because normal gallbladder mucosa does not contain neuroendocrine cells. Neuroendocrine cells can be detected at sites of intestinal metaplasia induced by chronic inflammation, which may be the initial step in the development of neuroendocrine tumor of the gallbladder. Anomalous union of the pancreaticobiliary duct (AUPBD) is an uncommon congenital anomaly that is frequently associated with choledocholithiasis, cholangitis, pancreatitis, and cancer of the gallbladder or bile duct. In AUPBD, cancers of the gallbladder and bile duct can be induced by chronic inflammation. We report herein a case of large-cell neuroendocrine tumor of the gallbladder associated with AUPBD.

Clonorchiasis is a trematodasis caused by ingestion of a raw fish that contains the infective cysts. In cases of early infection, the patients complained non-specific gastrointestinal symptoms, including anorexia, epigastric pain or diarrhea. In cases of long-standing infection, an association with gallstones, choledocholithiasis, cholangitis and cholangiocarcinoma has been reported. However, acute hemorrhagic complications of clonorchiasis are extremely rare. Herein, we report on a case of hemobilia that was caused by Clonorchis sinensis, and this was confirmed by operation.
