To investigate morphological changes in the endocrine pancreas of chicken after pancreatic duct ligation, experimental animals were subdivided to control, 12 hours, 1 day, 2 days, 4 days, 7 days and 10 days groupes and all of three pancreatic ducts of chicken were ligated by surgical procedure and then the morphological changes were observed. In pancreatic islets, the vacuolation and invasion of connective tissue were occurred in all experimental groups and dissociation of pancreatic islets was detected in 4 days after pancreatic duct ligation and hold out to 10 days. The peak of the morphological changes in pancreatic islets was detected in 4 days after pancreatic duct ligation. In the results of immunohistochemical methods against glucagon, insulin, somatostatin and bovine pancreatic polypeptide(BPP), the number of immunoreactive pancreatic islets were decreased but the size increased with time, so the number of immunoreactive cells in each pancreatic islets were increased. Glucagon-immunoreactive cells were not changed but insulin-immunoreactive cells were decreased with time(p<0.05). BPP-immunoreactive cells were increased in 2 days after pancreatic duct ligation and then decreased with time(p<0.05). Somatostatin-immunoreactive cells were increased with time(p<0.05) in dark islets.

To investigate morphological changes in the exocrine pancreas of chicken after pancreatic duct ligation, experimental animals were subdivided to control, 12 hours, 1 day, 2 days, 4 days, 7 days and 10 days groupes and all of three pancreatic ducts of chicken were ligated by surgical procedure and then the morphological changes were observed. In pancreatic ducts, once for a while the ducts were dilated on 12 hours after pancreatic duct ligation and then they were obstructed because of proliferated epithelial cells and connective tissues in pancreatic duct. Marginal dissociation of acini was detected in 12 hours after pancreatic duct ligation and then dissociation of acini was increased with time and finally in 4 days after pancreatic duct ligation the acini showed completely dissociation except periductular regions and around pancreatic islets. Most of dissociated acini cells showed marginal condensation of nuclear chromatin and atropy of cytoplasm, namely, apoptotic features were detected in dissociated acinar cells. Interacinar spaces of dissociated acinar regions were dilated and fulfilled with increased connective tissue and in 4 days after pancreatic duct ligation, deposition of lymphocytes and hemocytes was occurred.

Chronic pancreatitis is a rare problem in childhood and sometimes shows pancreatic calcification. The most common symptom is recurrent upper abdominal pain with or without associated nausea or vomiting. Pancreatic calcifications are virtually pathognomonic of chronic pancreatitis. In our case, however, chronic pancreatitis caused by multiple pancreatic stones in dilated pancreatic duct, which was very rare in childhood. Endoscopic retrograde cholangiopancreaticography (ERCP) is valuable in confirming the diagnosis and decision making process for further medical or surgical management of pancreatic disease. We experienced a case of chronic relapsing pancreatitis with pancreatic stones in 13-year-old girl who presented with recurrent upper abdominal pain. She was investigated with ERCP and treated by endoscopic sphincterotomy of sphincter of Oddi and by some stone removal with endoscopic basket. We report this case and review related literatures briefly.

Treatment of human calculi by extracorporeal shock-wave lithotripsy(ESWL) was introduced for kidney stones in 1980. This technology was then applied to the treatment of bile duct stones and pancreatic stones. Some reports have also shown that disintegration of pancreatic stones by extracorporeal shock-wave lithotripsy is possible with successful subsequent endoscopic extraction of the fragments at home ana abroad. We tried removal of pancreatic calcification stones by endoscopic procedures, but could't be removed because the basket got entagled in the endoscopy. We report one case of this pancreatic calcification stones ; the stones were successfully fragmented and completely removal by extracorporeal shock-wave lithotripsy.

척추동물 11목 21종의 췌장에서 insulin(B)세포, glucagon(A)세포, somatostatin( D)세포 및 pancreatic polypeptide(PP)세포 등을 면역세포화학적 방법으로 동정하여 이들의 출현율, 분포양상 및 형띨 등을 계통별로 비교하였다. 포유강에서는 전형적인 췌도를 형성하였고, 조강에서는 대 ·소췌도로 구분되었다. 내분비세포의 크기는 계통간의 차이가 있어서 B세포와 PP세포는 포유강의 것이 조강의 것에 비해 윤으나, A세포와 D세포는 그 반대이었다. 세포의 모양은 B세포의 경우 두 강에서 대체로 원형 및 난원형이었고, A세포와 D세포는 원형, 난원형 및 방추형이었다. PP세포는 방추형 및 난원형이 대다수 이었으며 간혹 원형 또는 다각형 등의 모습도 나타났다. 세포들의 출현율은 두 강에서 모두 B세포가가장 많았고, A, D및 PP세포 순으로 낮아졌다. B세포는포유강이 조강보다높았고, A, D및 PP세포는조강이 포유강보다 많았다. B세포는 조강의 경우 대췌도 주변부와 소췌도 중앙부에 분포하였고, 포유강에서는 중앙부에 균등하게 분포하였다. A와 0세포는 포유강에서 주로 췌도 주면부에 분포하나, 조강에서는 췌도중앙부에 위치하였다. PP세포는 두 강에서 대부분 췌도 주변부에 위치하였다. 일반적으로 두강에서 모두 외분비 선포조직에서도 내분비세포들이 출현하였으며 일부 종에서는 췌관상피에서도 내분비세포들이 드물게 나타났다.

To determine its usefulness and safety of extracorporeal shock-wave lithotripsy in common bile duct and pancreatic duct stones, we analyzed the results of 13 patients with common bile duct stones and 6 patients with pancreatic duct stones which were removed by endoscopic procedures using the balloon or basket, who was performed the extracorporeal shock-wave lithotripsy using the ultrasonography for stone localization with a spark gap type Lithotriptor(Dernier MPL 9000, Germany). Fragmentation and complete clearance of the common bile duct and pancreatic duct stones were obtained in 19 of 19 patients(100%). Apart from transient attacks of fever in 2 of 13 patients with common bile duct stones(15%) and mild elevation of serum amylase and lipase in 2 of 6 patients with pancreatic duct stones(33%), no other serious side effects were observed. In our experiences, extracorporeal shock-wave lithotripsy is a safe and useful treatment for endoscopically unretrievable common bile duct and pancreatic duct stones.

A pancreatico-pleural fistula (PPF), caused by rupture of a pancreatic pseudocyststectomy or obstruction of the pancreatic duct, is a rare condition. A 48-year-old man with chronic alcoholism was admitted with a massive pleural effusion. Pleural fluid studies revealed elevated amylase and lipase. A PPF complicated by a ruptured pancreatic pseudocyststectomy was diagnosed by computerized tomography scan. Although the symptoms improved with conservative management, (chest tube drainage, NPO, total parenteral nutrition, and a pancreatic secretion inhibitor), a distal pancreatectomy, including a pseudocystectomy and thoracotomy, were performed for an increasing size of the hemorrhagic pancreatic pseudocyststectomy and a recurrent hemorrhagic pleural effusion. There were no post-operative complications and the patient was discharged on post-operative day 27.

Over-density of pancreatic duct tail part on the endoscopic retrograde pancreatogram results from patient's position and inserted air during the study. The aim of this paper is to decide the filter angle to obtain an uniform density. Endoscopic retrograde pancreatography was performed to 234 patients, and angled wedge filter was used differently. They are $10^{\circ}$ (47), $20^{\circ}$ (45), $30^{\circ}$ (50), and $40^{\circ}$ (50). We also did not use wedge filter to 42 patients. We decided reliance degree in 95%. The statistical difference was p<0.05. The patients' sex rate was 1.8 : 1 between 18 and 87 years old(average age 58 years). Their body girth was 18.71 cm on the average. Of total 234 patients, difference of right and left average density was 0.01 by $30^{\circ}$ wedge filter, -0.08 $40^{\circ}$ wedge filter and 0.27 non-wedge filter. These average values of difference density were very significant statistically, and standard deviation also was close to regular distribution. In conclusion, there is a usefulness of angled wedge filter for increasing diagnostic value of pancreatic duct tall part on the endoscopic retrograde pancreatogram.

Recent studies suggest that sphincter of Oddi dysfunction (SOD) is one of the possible causes of unexplained recurrent acute pancreatitis in children. A 14-year-old boy who had suffered from idiopathic recurrent acute pancreatitis was diagnosed with SOD. Abdominal ultrasonography, computerized tomography, and magnetic resonance cholangiopancreatography revealed no evidence of stone, tumor, or pancreatic ductal anomaly. Endoscopic retrograde cholangiopancreatography (ERCP) and sphincter of Oddi manometry (SOM) revealed elevated basal pressure and tachyoddia consistent with SOD. Hence, an endoscopic pancreatic sphincterotomy was performed. We report a case of recurrent acute pancreatitis associated with SOD in a child. ERCP and SOM may be considered in patients with multiple unexplained attacks of pancreatic pain and negative abdominal imaging.

An 8-year-old boy presented with abdominal pain and poor oral intake for two months. Serum amylase and lipase levels were elevated. CT of the abdomen and chest X-ray showed two pseudocysts at the pancreatic uncinate process, pancreatitis with a parenchymal defect, a large amount of ascites, and a right pleural effusion. MR cholangiography and endoscopic retrograde cholangiopanreaticography revealed a pancreatic duct disruption. The patient was successfully treated with a chest tube placement and percutaneous drainage. After surgery, his general condition improved; the serum level of amylase normalized and the pleural effusion resolved. Pancreatic injuries are rare in pediatric blunt trauma; however, diagnostic difficulty is common with isolated blunt trauma. Therefore, a high index of suspicion should follow such an injury. We report the case of an 8-year-old boy with pancreas transection, ductal disruption, ascites, and pleural effusion who was successfully treated.
