Endoscopic treatment of chronic pancreatitis has drawn benefits from endoscopic procedures previously described for the main bile duct. Endotherapy is developing throughout the world. Cyst drainage procedures certainly represent the largest step forward in that non-surgical approach, whatever it is either direct (through the stomach or the duodenum) or indirect through the papilla in the duodenum. This procedure gives similar results to surgery with a lower morbidity. Pancreatic duct drainage associated with stone clearance is feasible and provides good results which have not yet been compared with those obtained thanks to surgery. Nonetheless, when the duct is not widely dilated it has been proven to be a satisfactory alternative to surgery. By contrast, chronic cholestasis does not appear to be a good indication of endotherapy.

Autoimmune pancreatitis (AIMP) is a recently described clinical entity causing chronic pancreatitis. It often presents with diffuse enlargement of the pancreas and/or a focal mass at the head of the pancreas causing common bile duct obstruction and jaundice. In most instances, AIMP is mistaken for pancreatic cancer. A number of laboratory abnormalities such as positive antinuclear antibody, hypergammaglobulinemia, and antibody to carbonic anhydrase are often present in these patients. Currently, pancreatic biopsy demonstrating characteristic histopathologic changes is essential to establish the diagnosis. We report the first case of AIMP presenting as a pancreatic tail mass and lower gastrointestinal bleed.

We report three cases of postoperative recurrent cholangitis due to a defective hepaticojejunal anastomosis. Causal diseases were alveolar echinococcosis of the liver, alcoholic chronic pancreatitis, liver colorectal metastases. Clinical presentation included major cholestasis and cachexia. Imaging explorations showed that cholangitis was due to an inversion of the Roux-en-Y jejunal loop which had been disposed in a wrong position. Clinical improvement was remarkable after reoperation and replacement of the defective loop in the right position. This exceptional cause of postoperative cholangitis after Roux-en-Y hepaticojejunal anastomosis must be identified and treated by prompt restorative surgery.

Fungal infection resulting in chronic pancreatitis is rare. We report a case of chronic pancreatitis due to fungal infection causing common bile duct obstruction and abdominal pain mimicking pancreatic cancer. Treatment included resection to cure the pain and rule out malignancy. Long-term effects of fungal infection may be seen more frequently as total parenteral nutrition, antibiotics, and foreign bodies (e.g., stents, drains, central venous catheters) are more often being used in the treatment of many diseases.

The prevalence and the mechanisms of hepatic fibrosis in chronic alcoholic pancreatitis remain uncertain. The aim of this study was to investigate the fibrogenic activity of the liver in patients with chronic pancreatitis and its relation with either the alcohol or cholestasis. Liver biopsies were obtained from 16 patients with chronic pancreatitis at the time of surgery and from 10 organ donors. Samples were processed for histologic examination to assess the presence and extent of fibrosis, inflammatory reactions, and cholestasis- and alcohol-related lesions. In other samples, the collagen content was measured by morphometry, and prolylhydroxylase activity was determined. Liver-function tests, ultrasonography, and endoscopic retrograde cholangiopancreatography were performed before surgery in all the patients. Of patients with chronic pancreatitis, 75% had significantly greater hepatic fibrosis and prolylhydroxylase activity than the control group. Moreover, prolylhydroxylase activity in patients with chronic pancreatitis was higher in those with cholestasis or partial obstruction of the common bile duct than in those without cholestasis or partial obstruction of the common bile duct. Both the fibrogenic activity and the collagen content in the livers of patients with chronic alcoholic pancreatitis are significantly increased, even in those without histologic lesions, and these alterations may be secondary to a partial occlusion of the common bile duct.

Magnetic resonance Cholangiopancreatography (MRCP) is a non-invasive imaging technique able to provide projectional images of the bile ducts. Different sequences, using both breath-hold and non-breath-hold acquisition techniques, have been employed in order to obtain MRCP images. The authors discuss technical aspects, considering both three-dimensional non-breath-hold techniques and two-dimensional breath-hold, multi-slice and thick slab sequences. Clinical applications of MRCP are evaluated, presenting data from both the literature and personal experience. The main indication for MRCP study is represented by the evaluation of common bile duct obstruction, with the aim of assessing the presence of the obstruction (accuracy 85-100%) and, subsequently, its level (accuracy 91-100%) and its cause. The utility of associating conventional MR images to MRCP in malignant strictures, in order to characterize and stage the malignant lesion, is also discussed. Finally, data are presented regarding the indications and the utility of MR-pancreatography in the evaluation of patients with pancreatic duct anomalies and chronic pancreatitis.

A 51 year old male patient with a history of chronic alcohol consumption and recurrent pancreatitis was referred to our hospital with jaundice, epigastric pain, severe diarrhoea and weight loss of 28 kg within the last 12 months. A CT scan of the abdomen 4 months before admission had shown a pancreatitis with free fluid around the corpus and tail of the pancreas as well as dilated intrahepatic bile ducts and a cavernous transformation of the portal vein. Moreover, a tumor (3.5 x 3.0 x 3.6 cm) with irregular contrast enhancement was seen within the left liver lobe. The patient was referred to us for further evaluation and treatment. The initial B-Mode sonogram revealed a bull's eye like well defined lesion (8.1 x 7.5 x 7.0 cm) within the left liver lobe, consistent with a tumour or abscess. Prior to a diagnostic needle biopsy a PTCD was performed in this case presenting with dilated intrahepatic bile ducts and having a history of Billroth II operation. An additional colour coded Duplex Doppler ultrasonography demonstrated a visceral artery aneurysm and prevented us from performing the diagnostic puncture. The aneurysm was assumed to originate from a variant or a branch of the left hepatic artery. Angiography revealed a pseudoaneurysm of the pancreaticoduodenal artery and coil embolization was performed because of the increasing size and the risk of a bleeding complication. Postinterventional colour duplex ultrasound measurement showed no blood flow within the aneurysm. Retrospectively, the pseudoaneurysm must have led to a compression of the common bile duct, since the patient did not develop cholestasis after embolization and removal of the PTCD. Thus, a pseudoaneurysm of the pancreaticoduodenal artery must be included in the differential diagnosis of liver tumours in patients with chronic pancreatitis, despite its unusual localization near the liver. Therefore, we suggest that colour coded ultrasonography should be applied to any unclear, bull's eye like lesion, even though this method alone cannot exactly determine the origin of the pseudoaneurysm. Interventional angiography remains the gold standard for the diagnosis and therapy of visceral artery aneurysm.

Up to present time there is no common view on the role of diverticuli of the papillar region of the duodenum (DPRD) in development of the strictures of terminal parts of the common bile duct and major pancreatic duct. The main method for the diagnosis of DPRD is fibroduodenoscopy (FDS). Relaxational FDS is the most informative method for detailed examination of diverticulum and for assessment of its interrelations with longitudinal crease and the major duodenal papilla (MDP). During the last 2 years all patients with DPRD underwent ERCPG, which helped to obtain more complete information of the presence and the character of the strictures of terminal parts of the common bile duct and the pancreatic duct. DPR has been revealed in 5% of patients with calculous cholecystitis and in 9.5% of patients with choledocholithiasis. Of the patients, admitted to the Institute for postcholecystectomy syndrome from 1994 to 1999, DPRD were revealed in 30% of cases. The patients with DPR and chronic pancreatitis of nonalcoholic and nonlithogenic etiology, made up 9% of all patients with DPR and chronic pancreatitis. In 87 patients with DPR, suffering from various surgical diseases, following changes of bile and pancreatic ducts were revealed: choledocholithiasis (47%), stenosis of the large bile duct (15%), strictures of terminal parts of the large bile duct and major pancreatic duct (10%). There is evidence, that para- and peripapillary diverticuli deteriorate evacuatory function of the bile and pancreatic tracts due to compression of terminal parts of the choledochus and the pancreatic ducts with strictures formation, which promote disturbances of the bile and pancreatic juice passage. Biliary stasis and pancreatic juice passage disturbances create favorable conditions for lithogenesis and promote development of cholangitis, mechanical jaundice and chronic pancreatitis. Patients with choledochal and major pancreatic duct strictures and stenoses of the papilla in DPR underwent EPST with favorable initial and long-term results. The authors suggest, that DPR are an important etiopathogenetic link in the development of many diseases of the organs of hepatobiliary region, associated with biliary and pancreatic hypertension.

Pain is a leading symptom in chronic pancreatitis (CP) and often its management necessitates surgical intervention. Nevertheless the presence of different hypotheses, the pathophysiology of pain is not understood, thus the indications for therapy remain controversial. Increased pressure within the ductal system and/or the parenchyma has been suggested to be one of the causes of pain. This controversial theory has been substantiated by the demonstration of a relationship between intrapancreatic pressure and intensity of pain. On the other hand, recent studies have shown the inflammatory involvement of intrapancreatic nerve fibres in a so called "neuroimmune interaction". In fact, infiltration of inflammatory cells around the nerves together with an increase in the number of nerve fibres in the fibrotic pancreatic tissue have been proposed as a possible cause of pain in chronic pancreatitis. Moreover, immunohistological studies have shown that the amount of neurotransmitters, such as substance P and calcitonin gene related peptide, is increased in afferent pancreatic nerves and a close interrelationship between pain and immune cell infiltration of the nerves has been reported in CP. In addition to these hypothesis, extrapancreatic causes such as common bile duct obstruction and duodenal stenosis are discussed. This article review points to the different pathogenic mechanisms of pancreatic pain in CP.

Authors report two cases of childhood chronic pancreatitis, causing severe symptoms and common bile duct stenosis with cholestasis. Both patients had to be operated on. Chronic pancreatitis with calcification led to significant common bile duct stenosis in a 13 years old girl. After ERCP a double bypass procedure was performed (Wirsungo-jejunostomy and hepatico-jejunostomy). During 42 months follow-up the patient remained pain- and symptom-free gaining 16 kilograms. In a 9 years old girl severe stenosis of the intrapancreatic common bile duct and a small duct type chronic pancreatitis with extensive fibrosis was found. Treatment was Roux-en-Y hepatico-jejunostomy. Thirty-four months after the operation she is symptom-free with normal enzyme parameters. Authors report results of genetic investigations performed on registered chronic pancreatitis children and their families in Hungary, including the two operated cases. Two of the 5 patients were hereditary type, despite negative family history. Cationic trypsinogen gene R122H (R117H) mutation were detected in both patients. Chronic non-hereditary pancreatitis is a very rare disease in childhood but may cause severe secondary conditions requiring surgery.
