A 68-year-old male presented with
abdominal pain
and
obstructive jaundice
. CT revealed a large mass in the pancreatic head that was initially interpreted as pancreatic carcinoma. Needle biopsy revealed only fibrous tissue with signs of chronic inflammation. Together with typical findings of an idiopathic retroperitoneal fibrosis, the final diagnosis of multifocal idiopathic fibrosclerosis with focal pseudotumorous pancreatic head fibrosis could be made.

The purpose of this review is to evaluate our current knowledge of the embryologic etiology of pancreaticobiliary maljunction (PBM), its diagnosis, clinical aspects, and treatment, and to clarify the mechanisms of PBM involvement in carcinogenesis. Although the embryologic etiology of PBM still awaits clarification, an arrest of the migration of the common duct of the biliary and pancreatic ducts inwards in the duodenal wall has hitherto been speculated to result in a long common channel in PBM. However, we propose the hypothesis that the etiology of PBM is caused by a disturbance in the embryonic connections (misarrangement) of the choledochopancreatic duct system in the extremely early embryo. That is, PBM is an anomaly caused by a misarrangement whereby the terminal bile duct joins with a branch of the ventral pancreatic duct system, including the main pancreatic duct. PBM is frequently associated with congenital bile duct cyst (CCBD). However, these two anomalies are thought to have different embryonic etiologies. The diagnostic criteria for PBM are the radiological and anatomical detection of the extramural location of the junction of the pancreatic and biliary ducts in the duodenal wall. However, in PBM patients with a short common duct (less than 1 cm in length), detection of the extramural location is difficult. The clinical features of PBM are intermittent
abdominal pain
, with or without elevation of pancreatic enzyme levels; and
obstructive jaundice
, with or without acute pancreatitis, while the clinical features of PBM patients with CCBD are primary bile duct stone and acute cholangitis. The optimum approach for the treatment of PBM is the prevention of the reciprocal reflux of bile and pancreatic juice in the pancreas and the bile duct system. To achieve these aims, the surgical approach is most effective, and complete biliary diversion procedures with bile duct resection (for example, choledochoduodenostomy or choledochojejunostomy of the Roux-en-Y type) are most useful. Recently, it has been recognized that the development of biliary ductal carcinoma is associated with PBM. That is, the development of gallbladder cancer occurs frequently in PBM patients without CCBD, and bile duct cancer originating from the cyst wall also occurs in PBM patients with CCBD. It is speculated that the pathogenesis of the bile duct or gallbladder cancer in PBM patients involves the reciprocal reflux of bile and pancreatic juice. Investigations of epithelial cell proliferation in the gallbladder of PBM patients, and of K- ras mutations and p53 suppressor gene mutations, loss of heterozygosity of p53, and overexpression of the p53 gene product in gallbladder cancer and noncancerous lesions in PBM patients have been carried out in various laboratories around the world. The results support the conclusion that PBM is a high risk factor for the development of bile duct carcinoma.

Chronic pancreatitis is a rare differential diagnosis of
obstructive jaundice
and/or recurrent
abdominal pain
in childhood and adolescence. The hereditary calcifying and the noncalcifying obstructive form are the two major forms of juvenile chronic pancreatitis. Other causes include cystic fibrosis, hyperparathyroidism, hyperlipoproteinemia and ascariasis. Even less common is the so called idiopathic or fibrosing pancreatitis. Since the first description by Comfort in 1946 only 41 further cases of juvenile idiopathic fibrosing pancreatitis have been published. An association with gene mutations (PRSS1, SPINK1, CTFR-5T genotype) is suspected. We report the cases of a 17-year-old male patient who presented with painless
obstructive jaundice
and a 16-year-old female patient who presented with
abdominal pain
and
obstructive jaundice
. Both patients underwent surgical treatment with duodenum-preserving pancreatic head resection. The relevant literature with special regard to modern pancreatic surgery is reviewed to give an overview about this rare but surgically treatable pediatric condition, which merits the attention of pediatricians and gastroenterologists in cases of children and adolescents suffering from unexplained
abdominal pain
.

A 45-year-old man was suffering from
abdominal pain
and vomiting. He was admitted to our hospital with a diagnosis of ileus and
obstructive jaundice
. He had undergone Roux-en-Y anastomosis for choledocholithiasis 14 years earlier. A computed tomography scan revealed a dilated afferent loop and dilated intrahepatic bile duct. Upper gastrointestinal examination with contrast medium and percutaneous transhepatic cholangiography showed a high intestinal obstruction around the jejunojejunal anastomosis. The patient underwent laparotomy based on a diagnosis of
obstructive jaundice
due to ileus. During the operation, he was found to have internal herniation of the small bowel through a rent in the mesentery around the Roux-en-Y anastomosis for choledochojejunostomy. The hernia was reduced, and bowel resection was performed due to stenosis of the afferent loop. Jejunojejunal anastomosis was re-performed and the defect in the mesocolon was closed. Internal herniation after Roux-en-Y anastomosis is a rare sequela, but it should be recognized that this complication can occur after Roux-en-Y anastomosis. For prevention of internal herniation around the Roux-en-Y limb, secure closing of the mesenteric defects is important.

We present herein a case of a 75-year-old Japanese man who had developed a pancreatic abscess 7 years after a longitudinal pancreatojejunostomy for chronic pancreatitis. The patient, a heavy drinker of alcohol, underwent surgical decompression of a ductal obstruction to relieve persistent
abdominal pain
due to severely calcifying chronic pancreatitis. After the surgery, he stopped drinking alcohol and was treated with insulin to control secondary diabetes mellitus. Thereafter, his symptoms disappeared. Seven years after the surgery, however, he was hospitalized due to
obstructive jaundice
, high-grade fever, and right hypochondria pain. Ultrasound and computed tomographic scans of the abdomen both disclosed a cystic mass, approximately 6 cm in size, in the pancreatic head. Magnetic resonance imaging strongly suggested a pancreatic abscess with necrotic fluid and debris. First, percutaneous transhepatic cholangiodrainage (PTCD) was done to treat the progressively
obstructive jaundice
. Subsequently, fine-needle aspiration of the pancreatic abscess was performed under ultrasound guidance. Enterococcus avium and Klebsiella oxytoca were revealed by culture of abscess aspirates. He was successfully cured by treatment with both appropriate antibiotic and continuous PTCD for the
obstructive jaundice
.

Pseudoaneurysm of the cystic artery is a rare cause of hemobilia, with only 11 cases having been reported in the English literature. We report this unusual condition in a 62-year-old Japanese man whose chief complaint was repeated upper
abdominal pain
. A liver function test showed
obstructive jaundice
, and endoscopy revealed a small amount of blood coming from the papilla of Vater. We diagnosed him as having hemobilia, and immediate angiography was performed. The results demonstrated a pseudoaneurysm arising in the cystic artery. Selective embolization of the cystic artery then followed. Ten days later the patient underwent elective cholecystectomy and had a good postoperative course. Microscopically, the resected specimen revealed caliculous cholecystitis and an organized pseudoaneurysm perforating the lumen of the gallbladder. We supposed that this pseudoaneurysm was associated with the inflammatory reaction seen with the acute cholecystitis. This case emphasizes the need for a high level of awareness of hemobilia whenever bleeding is associated with signs of biliary disorders. Immediate angiography and embolization of the pseudoaneurysm followed by radical surgery may be the preferred strategy. We believe this is the first reported case of successful "two-step" treatment of such a pseudoaneurysm.

We report two cases of a nonparasitic solitary huge liver cyst. The first case, that of a 42-year-old woman, was admitted with a chief complaint of upper
abdominal pain
. Computed tomography (CT) scans revealed a huge cyst, 10 cm in diameter, in segments 4 and 5 of the liver, and spontaneous rupture of the cyst with intracystic hemorrhage. Her general condition was improved by transcatheter arterial embolization (TAE). Percutaneous cystic needle aspiration cytological examination revealed no malignant cells, so she was discharged. After 3 weeks, however, the cyst had increased in size, and simple cystectomy was performed. Histological examination proved the cyst to be benign. The patient in the second case, a 70-year-old man, was admitted with epigastric discomfort and
obstructive jaundice
. CT scans revealed a huge liver cyst, 18 x 15 cm, in the right lobe of the liver, with dilation of the bile duct in the lateral segment. Magnetic resonance cholangiopancreatography showed compression of the left hepatic duct by the cyst and dilation of the bile duct in the lateral segment. Endoscopic retrograde cholangiopancreatography disclosed no communication between the bile duct and the cyst. Percutaneous transhepatic cyst drainage was performed, and minocycline hydrochloride was infused. The cyst was reduced in size, and the reduction has been maintained for 20 months since treatment.

Cholangiocarcinoma (CC) is a malignant neoplasm deriving from intra- and extrahepatic bile ducts. It affects both sexes, and is most prevalent at the age 50 to 70. Chronic nonspecific ulcerative colitis, primary sclerosing cholangitis, hepatolithiasis, congenital hepatic fibrosis, and Caroli's disease may lead to the increased incidence of CC. Recently, hepatic cirrhosis in the course of virus-associated chronic hepatitis has been suggested to be involved in the pathogenesis CC. Histologically, 90-95% of CC are well differentiated adenocarcinomas. Usually the tumor grows slowly and metastazes late locally and even less frequently extrahepaticly. CC often causes symptoms by blocking the bile ducts,
abdominal pain
, weight loss, signs of portal hypertension, rare ascites and thrombophlebitis. Serum chemistry was compatible with
obstructive jaundice
. The increased expression of CEA, Ca19-9, as well as loss or reduction of sialomucin/sulfomucin concentration in the biliary lining epithelium may be indicative of malignant changes. CC as usually non-vascularized nonencapsulated tumor with a large amount of fibrosis. It is isochogenic in classical USG, CT or MRI. MRCP-magnetic resonance cholangiopancreatography and virtual endoscopy are more helpful methods on the diagnostics of CC. Recently, FDG positron emission tomography has been suggested to be a sensitive technique in identifying small bile duct cancers. Surgical excision of the lesion confirmed localized CC. The adjuvant radio- and chemotherapy and transplantation are not satisfactory. Palliative therapy includes surgical biliary-intestinal bypass procedures as well as operative and nonoperative techniques for biliary intestinal drainage. Recently, the local treatment of CC by photodynamic therapy as a palliative strategy is very promising. Ordinary CC is reported as a neoplasm with a poor prognosis. Post resection 5-year survival is affirmed in about 25% of CC, whereas after palliative treatment only 1 year.

We report two cases of pancreatic tuberculosis. The first patent (who tested positive for HIV) presented with
abdominal pain
, fever, weight loss, anorexia and tender epigastric lump. The CT scan revealed multiple small abscesses in the pancreas. The second patients, who had no evidence of immunodeficiency, presented with constitutional symptoms and
obstructive jaundice
. The CT scan revealed a mass in the pancreatic head with peripancreatic lymph nodes and dilatation of the intrahepatic and extrahepatic biliary tree. None of the patients had Mycobacterium tuberculosis infection of the lung or any other organ. Fine-needle aspiration biopsy clinched the diagnosis in both the patients, with caseation necrosis and plenty of acid-fast bacilli in the first patient, and characteristic granulomatous inflammation of the pancreas in the other. The first patient died during the index hospitalization, while the other responded well to antitubercular treatment with improvement in symptoms and radiological clearance of the initial lesions.

Nine children aged between 2 months and 11 years, who had congenital dilatation of extrahepatic biliary tract, with or without intrahepatic dilatation, are presented. The radiological studies performed in eight patients demonstrated abnormal choledochopancreatico ductal junction. Thus, a long common channel is formed out of the duodenal wall, leading to a continuous reflux of pancreatic juice into the biliary system, chronic inflammation of biliary tract wall, fibrosis of muscular layer and finally different types of dilatations. The main clinical findings were upper
abdominal pain
, vomiting, or
obstructive jaundice
. In only one child the dilatation was cystic type and the clinical manifestation was palpable abdominal mass. In eight patients the initial diagnosis of biliary tract dilatation was made through abdominal ultrasound and in one case by direct visualization through emergent exploratory laparotomy. The final confirmation of the presence of long common channel was made by preoperative endoscopic retrograde cholangiopancreatography or intraoperative cholangiogram. The radiologic investigation was not performed in only one case due to bad clinical conditions. The surgical treatment indicated to all cases was Roux- en- Y hepatic- jejunostomy. The late follow up demonstrated that all patients are well and assymptomatic.
