A santorinicele is defined as a focal cystic dilatation of the terminal portion of the dorsal pancreatic duct at the minor papilla. Most cases reported previously were associated with pancreas divisum and a santorinicele without pancreas divisum is known to be rare. We recently experienced a typical case of a santorinicele without pancreas divisum in a 67-yr-old woman with abdominal pain and hematochezia, subsequently proven to be the result of an ischemic colitis. The santorinicele was diagnosed incidentally with multi-detector row computed tomography using a minimum intensity projection technique, which clearly showed a cystic dilatation of the terminal portion of the dorsal pancreatic duct and a communication between the ventral and dorsal pancreatic ducts. This finding was also confirmed by a magnetic resonance cholangiopancreatography.

Though congenital anomalies of the pancreas and pancreatic duct are relatively uncommon and they are often discovered as an incidental finding in asymptomatic patients, some of these anomalies may lead to various clinical symptoms such as recurrent abdominal pain, nausea and vomiting. Recognition of these anomalies is important because these anomalies may be a surgically correctable cause of recurrent pancreatitis or the cause of gastric outlet obstruction. An awareness of these anomalies may help in surgical planning and prevent inadvertent ductal injury. The purpose of this article is to review normal pancreatic embryology, the appearance of ductal anatomic variants and developmental anomalies of the pancreas, with emphasis on magnetic resonance cholangiopancreaticography and multidetector computed tomography.

Chronic pancreatitis causes a variety of complications such as glucose intolerance, pancreatic pseudocyst and duodenal obstruction. However pericardial effusion is very rarely complicated with chronic pancreatitis and life-threatening. The hypothesis of the development of pleuropericardial effusion in chronic pancreatitis has been variously proposed; fistula formation through esophageal or aortic hiatus, local transfer of pancreatic enzyme. Recently, we experienced a case of pleuropericardial effusion complicated by chronic recurrent pancreatitis causing cardiac tamponade. There was a contrast leakage appearing from the pancreatic duct to the mediastinum in endoscopic retrograde pancreaticography. The transpapillary pancreatic stent insertion led to the disappearance of pleuropericardial effusion on the radiography. We report this unusual manifestation of chronic recurrent pancreatitis with the review of literature.

OBJECTIVE: Since choledochal cyst is frequently associated with the anomalous union of pancreaticobiliary duct (AUPBD), AUPBD has been regarded to be the etiologic factor of choledochal cyst. However, the clinical significance of AUPBD an patients with choledochal cyst has not been clearly defined. Therefore, to clarify the significance of AUPBD in choledochal cyst patients, we compared the clinical features of patients with choledochal cyst according to the presence or absence of AUPBD. METHODS: Among 52 cases which were diagnosed as choledochal cyst out of 5,037 ERCP referrals between August 1990 and December 1996, we selected 44 cases, in which the pancreaticobiliary junction was clearly visualized on cholangio-pancreaticography. These cases were divided into AUPBD-present group (n = 28) and AUPBD-absent group (n = 16). Clinical features were compared between the two groups. Furthermore, in AUPBD-present group, clinical data were also analyzed according to Kimura's classification of AUPBD. RESULTS: In our study, AUPBD was associated with choledochal cyst in 28 (64%) cases. AUPBD was found only in type I and IV according to Todani's classification of choledochal cyst. There were no significant differences between the AUPBD-present group and the AUPBD-absent group in the incidence of gallstone disease, while the incidence of acute inflammation was 93% (26/28) in the AUPBD-absent group (p < 0.01). Carcinoma developed only in the AUOBD-present group (9/28, 32%) (p < 0.05). Pancreatic disorders (i.e. pancreatic stone, pancreatitis or pancreatic cancer) occurred in 12 of 28 cases in the AUPBD-present group (43%), while only in 1 of 16 cases in the AUPBD-absent group (6%) (p < 0.05). CONCLUSION: AUPBD associated with choledochal cyst may have implications not only as a possible etiologic factor but also as an important factor that may affect the clinical course, surgical planning and prognosis. In cases with choledochal cyst, we should make an effort to evaluate the presence of AUPBD.

Previously reported series suggested that the morbidity rate of internal surgical drainage procedure alone was about 15% and the mortality rate was less than 5% in patients with pancreatic pseudocysts. Recently, ultrasonography or CT-guided percutaneous drainage and endoscopic drainage techniques have created a new dimension of invasive, non-surgical treatment options for these patients. In the absence of prospective, randomized, controlled studies comparing outcomes of different pseudocysts drainage techniques, the decision as to which method should be employed often lies with local expertise and enthusiasm. In our experience, radiologic percutaneous drainage with subsequent transpapillary endosopic drainage had a high success rate and was relatively less difficult which resulted in rapid clinical improvement. We report three cases of pancreatic pseudocysts treated with percutaneous drainage as a first-line treatment followed by endoscopic treatment.

We report a case of a mediastinal pseudocyst with a pleural effusion that developed in a patient suffering from alcohol-related chronic pancreatitis. A 53-year-old man was admitted to another institution complaining of pleuritic chest pain and coughing. A chest X-ray revealed a pleural effusion with a collapse of the right middle and lower lobes. Pleural fluid taken by thoracentesis was exudative, and the patient was transferred to our institution. A CT scan showed a loculated cystic lesion in the mediastinum and pancreatic changes that were consistent with chronic pancreatitis. The endoscopic retrograde cholangiopancreatography (ERCP) findings were compatible with chronic pancreatitis showing severe pancreatic ductal stricture at the head with an upstream dilation and distal bile duct stricture. After a one week of treatment with fasting and octreotide without improvement, both pancreatic and biliary stents were placed endoscopically. After stenting, the pleural effusion and pseudocyst rapidly resolved. The stents were changed 3 months later, at which time a repeated CT demonstrated a complete resolution of the pseudocyst. Since the initial stenting, he has been followed up for 7 months and is doing well with no recurrence of the symptoms, but he will need to undergo regular stent changes. Overall, endoscopic pancreatic stenting appears to be a good option for managing selected cases of mediastinal pancreatic pseudocysts.

A 64 year-old male, with a history of alcoholism, presented at our hospital with dyspnea. He had a history of admission to hospital for treatment of chronic pancreatitis 4 month ago. Chest radiography showed a marked amount of right pleural effusion. Thoracentesis revealed an exudate of amylase-rich fluid. After conservative management he was discharged, but 1 month later increased right pleural effusion was detected. A pancreaticopleural fistula was detected on ERCP and abdomen CT. After 2 months of conservative management, there had been no improvement of the fistula; therefore, the authors decided to operate. The pancreas was hard and atrophic, with severe adhesion to adjacent tissues. Several pancreatic duct stones were found intraoperatively, with a pseudocyst was also found at the body portion. A suspicious fistula tract was observed at the posterior aspect of the body, which was subsequently ligated. A distal pancreatectomy, with a lateral pancreaticojejunostomy, and an additional side-to-side choledochojejunostomy were performed. A small amount of right pleural effusion was detected, with thoracentesis performed on the 8th postoperative day. The pleural effusion did not show a pancreatic juice nature, with amylase and protein levels of 9 U/L and 2,127 mg/L, respectively. No further increase in the amount of pleural effusion was observed, and the patient was discharged on the 16th postoperative day, without any complications. There was no evidence of recurrence at the 6 month follow up.

Lung cancer metastases can occur in almost any organ. However, metastasis of small cell lung cancer to the pancreas is rare. Moreover, not all cases present with clinically diagnosed pancreatitis. We recently treated a patient with small cell lung carcinoma that invaded the pancreatic duct causing acute pancreatitis. Generally, the treatment for tumor-induced acute pancreatitis is initially supportive followed by aggressive chemotherapy or surgery. If the patient can tolerate the insertion of an endoscopic intrapancreatic stent, this is performed in addition to chemotherapy and surgery; this approach offers a safe and effective treatment modality for such patients.
