The patient was a 22 year-old male. Hereditary chronic pancreatitis was suspected as a diagnosis since his mother's uncle had been operated on for chronic pancreatitis 14 years previously at the age of 64 years and his mother had been operated on for chronic pancreatitis with calculi 5 years previously at the age of 40 years. Surgery was needed, since: 1) he had experienced abdominal pain for 8 years; 2) endoscopic retrograde cholangiopancreatography (ERCP) revealed a marked irregular dilatation in the main pancreatic duct and a marked irregular dilatation and protein plugs in the ductule of the tail of the pancreas; and, 3) pancreatic functional diagnostic (PFD) test examination showed a 75% decrease in exocrine function. If a surgical procedure had not been performed, the patient would likely have experienced calculi formation in the pancreas and a further decrease in exocrine function. Since the patient was very young and had many protein plugs in the dilated ductule of the tail of the pancreas, we decided to perform a spleen-preserving Puestow's procedure with removal of the tail of the pancreas. Clinical and pathological findings of hereditary pancreatitis are reviewed.

Hereditary chronic pancreatitis (HCP) is a very rare form of early onset chronic pancreatitis. With the exception of the young age at diagnosis and a slower progression, the clinical course, morphological features and laboratory findings of HCP do not differ from those of patients with alcoholic chronic pancreatitis. As well, diagnostic criteria and treatment of HCP resemble that of chronic pancreatitis of other causes. The clinical presentation is highly variable and includes chronic abdominal pain, impairment of endocrine and exocrine pancreatic function, nausea and vomiting, maldigestion, diabetes, pseudocysts, bile duct and duodenal obstruction, and rarely pancreatic cancer. Fortunately, most patients have a mild disease. Mutations in the PRSS1 gene, encoding cationic trypsinogen, play a causative role in chronic pancreatitis. It has been shown that the PRSS1 mutations increase autocatalytic conversion of trypsinogen to active trypsin, and thus probably cause premature, intrapancreatic trypsinogen activation disturbing the intrapancreatic balance of proteases and their inhibitors. Other genes, such as the anionic trypsinogen (PRSS2), the serine protease inhibitor, Kazal type 1 (SPINK1) and the cystic fibrosis transmembrane conductance regulator (CFTR) have been found to be associated with chronic pancreatitis (idiopathic and hereditary) as well. Genetic testing should only be performed in carefully selected patients by direct DNA sequencing and antenatal diagnosis should not be encouraged. Treatment focuses on enzyme and nutritional supplementation, pain management, pancreatic diabetes, and local organ complications, such as pseudocysts, bile duct or duodenal obstruction. The disease course and prognosis of patients with HCP is unpredictable. Pancreatic cancer risk is elevated. Therefore, HCP patients should strongly avoid environmental risk factors for pancreatic cancer.

Apart from young age at diagnosis and a slower progression, the clinical course, morphological features and laboratory findings of HCP do not differ from those of patients with alcoholic chronic pancreatitis. Diagnostic criteria and treatment of HCP also resemble those of chronic pancreatitis of other causes. The clinical presentation is highly variable and includes chronic abdominal pain, impairment of endocrine and exocrine pancreatic function, nausea and vomiting, maldigestion, diabetes, pseudocysts, bile-duct and duodenal obstruction, and rarely pancreatic cancer.
