Isolated injury to the pancreas after abdominal trauma is uncommon, and a delay in diagnosis and treatment can increase the morbidity and mortality. Therapeutic decisions with respect to pancreatic trauma are usually made based on the site of injury and the status of the pancreatic ductal system. In this report, we describe the surgical management of pancreatic head transection as an isolated injury following blunt abdominal trauma. A 55-year-old man presented with epigastric pain that radiated to the back. Abdominal computed tomography revealed a hematoma in the pancreatic head and upstream dilatation of the main pancreatic duct. Endoscopic retrograde cholangiopancreatography showed complete disruption of and contrast leakage from the main pancreatic duct in the pancreatic head region with a nonenhanced upstream duct. Emergency pancreaticoduodenectomy was successfully performed, and the patient was discharged on postoperative day 9 without any complications.

The anomalous pancreaticobiliary duct union (APBDU) might cause the formation of choledochal cyst and malignancies of hepatopancreaticobiliary system. The purpose of this study is to make an experimental animal model of APBDU similar to that of human. One to two-month-old Mongrel dogs (n=12) were divided into two groups; the control group (n=2) had a sham operation performed, and in the experimental group (n=10) the end of distal ' common bile duct (CBD) was anastomosed to the side of the dorsal pancreatic duct making APBDD. Serum was obtained for chemical analysis on the 10th postoperative day. The dogs were sacrificed at the 5th week (n=3), the 6th week (n=3), the 7th week (n=2), the 8th week (n=2) and the 6th month (n=2) after the experimental surgery. With sacrifice, operative cholangiogram was taken, and bile juice was obtained for chemistry and bacterial culture. The en-bloc specimens of the hepatopancreaticobiliary system were removed for microscopic examination. Serum and bile juice amylase levels were elevated in the experimental group(n=10), but not in the control group(n=2). Operative cholangiograms of control group revealed no evidence of bile duct dilatation.. On the other hand, the bile duct in the experimental group was markedly dilated without any evidence of stenosis at the anastomosis site (n=10). Histologic examination of the hepatopancreaticobiliary system in the experimental group resembled the findings of choledochal cyst in human. The APBDU of this animal model can produce bile duct dilatation by pancreaticobiliary reflux. We think that this animal model can be potentially promising for the research about the APBDU associated hepatopancreaticobiliary diseases.

An 18-year-old woman with annular pancreas and duodenal duplication presented with recurrent acute pancreatitis and underwent a resection of duodenal duplication. However, the patient experienced recurrent abdominal pain after resection. Abdominal computed tomography and magnetic resonance imaging showed a dilatation of the peripheral pancreatic duct and stenosis and malformation of both the Wirsung's and Santorini's duct due to multiple stones. The modified puestow procedure was performed. The main pancreatic ducts in the body and tail were opened, and the intrapancreatic common bile duct was preserved. A Roux-en-Y pancreatico-jejunostomy was performed for reconstructing the pancreaticobiliary system after removing the ductal protein plug. The patient experienced no abdominal pain, no significant elevation of the serum amylase and lipase levels, and no stone formation during the 2 years of follow-up. This procedure is considered to be beneficial for pediatric patients with chronic pancreatitis due to annular pancreas and duodenal duplication.

Objective: To evaluate the role of percutaneous pancreatic stent placement in postoperative pancreaticojejunostomy stenosis (PJS). Materials and Methods: This retrospective single-center study included seven procedures in five patients (four males and one female; median age, 63 years) who underwent percutaneous pancreatic stent placement for postoperative PJS between January 2005 and December 2021. The patients were referred to interventional radiology because of unfavorable anatomy or bowel abnormalities. The pancreatic duct was accessed under ultrasound and/or computed tomography guidance. A stent was placed after balloon dilatation of the PJS. Moreover, plastic stents were placed for the first two procedures, whereas bare-metal stents were used for the remaining five procedures. Technical success was defined as the successful placement of stents for the PJS, meanwhile, clinical success was defined as the normalization of pancreatic enzymes without recurrence of pancreatitis. Results: Pancreatic duct access and stent placement were successfully performed in all patients (technical success rate: 100%). All the procedures initially yielded clinical success. However, recurrence of pancreatitis was observed after two procedures that used plastic stents because of stent migration at 0.3 and 3 months after the procedure. In contrast, no instances of recurrent pancreatitis were noted after metal stent placement for a follow-up duration of 1-36 months. No serious procedure-related adverse events were observed. Conclusion: Percutaneous pancreatic stent placement may be a viable option for patients with postoperative PJS in whom an endoscopic approach is not feasible. Metal stents may be considered over plastic stents for the management of PJS, considering the possible lower stent migration and infeasibility of frequent endoscopic stent exchange due to the altered anatomy.

Purpose: Choledochal cyst is a cystic dilatation of common bile duct. Although the etiology is presently uncertain, anomalous pancreaticobiliary ductal union (APBDU) is thought to be a major etiology of choledochal cyst. In this study, we analyzed the clinical and anatomical characteristics and pathologies of patients diagnosed with choledochal cyst in a single institute for 25 years. Methods: A total of 113 patients, diagnosed with choledochal cyst and who received an operation in Severance Children's Hospital from January 1988 to May 2013, were included. Medical records were reviewed, including clinical and demographic data, surgical procedures. Abdominal ultrasonography, magnetic resonance cholangiopancreatography, and intraoperative cholangiography were used as diagnostic tools for evaluation and classification of choledochal cyst and the presence of anomalous pancreaticobiliary ductal union. Todani's classification, and relationship between APBDU and surgical pathology. Results: Among 113 patients, 77 patients (68.1%) presented symptoms such as hepatitis, pancreatitis and/or cholecystitis. Eighty three patients (73.5%) had APBDU, and 94 patients (83.2%) showed inflammatory pathologic changes. APBDU, pathologic inflammation, and serological abnormalities such as hepatitis or pancreatitis showed a statistically significant correlation to one another. Conclusion: APBDU is thought to be one of the etiologic factors of choledochal cyst. It is related to the inflammatory changes in bile duct that can lead to the cystic dilatation.

췌관 내 유두상 점액종양은 매우 다양한 자연경과와 예후를 가지고 있어 추적 검사방법, 간격, 기간 등이 아직도 논란이 되고 있다. 이 종양에 대한 진료지침들에서는 추적 검사를 받을 환자군과 수술적 치료가 필요한 군으로 분류하기 위하여 악성화 고위험 특징 또는 절대적 수술 적응증과 걱정스러운 특징 또는 상대적 수술 적응증으로 분류하였다. 걱정스러운 특징이나 고위험 특징이 없는 분지형 유두상 점액종양은 혼합형이나 주췌관 종양에 비하여 악성화 위험성이 매우 낮다고 보고되고 있다. 그러나 저위험 특징을 가진 환자들을 장기간 추적한 연구에서 시간이 지남에 따라서 췌장암 발생이 점점 높아지고 있다고 보고하고 있어 지속적인 장기간 추적 검사가 필요하다. 혼합형과 주췌관형 유두상 점액종양은 악성화 가능성이 매우 높아 수술적 치료가 필요하다고 알려져 있다. 무결절이고 주췌관 직경이 10 mm 미만으로 분절형 주췌관 확장을 가진 환자들은 악성화 가능성이 낮아서 즉각적인 수술보다는 주의 깊은 추적관찰을 고려해볼 수 있다. 고령이나 기저질환을 동반한 환자의 치료 방향을 결정할 때는 췌장암 발생의 위험도와 수술의 위험성을 균형있게 평가해야 한다.

카롤리병은 섬유낭성 간질환이다. 상염색체 열성 장애로 담관의 선천적 다발성 확장이 특징이다. 카롤리병을 진단하는 방법으로 전산화단층촬영, 자기공명영상 검사, 담관 조영술, 초음파 검사가 있다. 전산화단층촬영검사는 섬유다낭성 간 질환을 감지하고 구별하는데 필수적이며, 간 내 담관의 확장을 판별하는 데 유용하다. 하지만 조영제를 사용함으로써 일어날 수 있는 부작용에 대한 인지가 필요하다. 자기공명영상검사는 대표적으로 자기공명담췌관조영술 방법을 이용한다. 비침습적 검사로 환자의 고통을 경감할 수 있고, 담췌관부의 해부학적 구조와 병변 유무를 쉽고 빠르게 관찰이 가능하다. 담관 조영술은 비대해진 담관 전체에 걸친 여러 낭성 확장을 직접 시각화할 수 있는 효과적인 진단 방법이다. 하지만 이 시술 또한 침습적인 시술이므로 진단이 아닌 치료 목적으로 권장된다. 초음파 검사는 전산화단층촬영과 유사한 소견을 확인할 수 있다. 간동맥 뿌리는 기존의 그레이 스케일 초음파에서 증명하기 쉽지 않다. 하지만 관 내 혈관 뿌리를 가진 확장된 담관을 묘사할 수 있을 뿐만 아니라 관 내 색상 도플러 신호를 쉽게 식별할 수 있다는 점에서 임상적 가치를 갖고 있다. 최근엔 영상진단의 발전으로 전산화단층촬영 검사, 자기공명영상 검사, 담관 조영술, 초음파 검사 등으로 조기 진단이 가능해졌다. 조기 진단을 통해 치료 후에 장기적인 예후가 개선될 수 있도록 영상 진단 발전에 더욱 기여하고자 각 검사별 카롤리병에 대하여 어떠한 양상이 나타나는지 고찰하였다
