A choledochocele is an expanded sac of the duodenal side of the distal common bile duct (CBD), and is categorized as a type III choledochal cyst. Unlike other choledochal cysts, it can be easily overlooked because of its very low prevalence, non-specific clinical symptoms, and lack of distinctive radiological findings. However, a patient having a repeated pancreaticobiliary disorder with an unknown origin, frequent abdominal pain after cholecystectomy, or repeated non-specific gastrointestinal symptoms can be suspected as having a choledochocele, and a more accurate diagnosis can be achieved via endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound. Because it rarely becomes malignant, a choledochocele can be treated via endoscopic sphincterotomy (EST) and surgical treatment. The authors were able to diagnose choledochocele accompanied by a stone in a patient admitted to the authors' hospital due to cholangitis and pancreatitis. The patient's condition was suspected to have been caused by a distal CBD stone detected via multiple detector computed tomography and ERCP, and was successfully treated via EST.

Background/Aims: Difficult biliary cannulation is an important risk factor for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP). Therefore, this study aimed to identify the factors that predict difficult cannulation for common bile duct stones (CBDS) to reduce the risk for PEP. Methods: This multicenter retrospective study included 1,406 consecutive patients with native papillae who underwent ERCP for CBDS. Factors predicting difficult cannulation for CBDS were identified using univariate and multivariate analyses. Results: Univariate analysis showed that six factors significantly predicted difficult cannulation: ERCP performed by non-expert endoscopists, low-volume center, absence of acute cholangitis, normal serum bilirubin, intradiverticular papilla, and type of major duodenal papilla. Multivariate analysis identified ERCP performed by non-expert endoscopists (odds ratio [OR], 2.5; p<0.001), low-volume center (OR, 1.6; p<0.001), intradiverticular papilla (OR, 1.3; p=0.007), normal serum bilirubin (OR, 1.3; p=0.038), and absence of acute cholangitis (OR, 1.3; p=0.049) as factors significantly predicting difficult cannulation for CBDS. Conclusions: Initial cannulation by an experienced endoscopist, early rescue cannulation, or early takeover by an experienced endoscopist should be considered when performing ERCP for CBDS in the presence of factors predicting difficult cannulation.

Background/Aims: There are few studies assessed the efficacy and mortality of endoscopic retrograde cholangiopancreatography (ERCP) for the removal of common bile duct (CBD) stones in the elderly aged ≥90 years. We aimed to assess the safety and efficacy of endoscopic removal of CBD stones in nonagenarians. Methods: We retrospectively reviewed ERCP reports for CBD stone removal. The endoscopic and therapeutic outcomes were collected. The length of stay (LOS), the total number of adverse events, and mortality rate were compared between groups. Results: A total of 125 nonagenarians were compared with 1,370 controls (65-89 years old individuals). The mean LOS for nonagenarians was significantly higher than in controls (13.6 days vs. 6.5 days). Completed intended treatment was similar in the nonagenarians and controls (89.8% and 89.5%, respectively). The overall complication rate did not differ between the groups. However, nonagenarians had a higher incidence of post-ERCP pneumonia (3.9%). None of the nonagenarians were readmitted to the hospital within 7 days. Four nonagenarians (3.2%) and 25 (1.8%) controls died within 30 days. Conclusions: Advanced age alone did not affect the decision to perform the procedure. However, prompt diagnosis and treatment of post-ERCP pneumonia in nonagenarians could improve the outcomes and reduce mortality.

A 75-year-old man with chronic cholangitis and a common bile duct stone that was not previously identified was admitted for right upper quadrant pain. Acute cholecystitis with cholangitis was suspected on abdominal computed tomography (CT); therefore, endoscopic retrograde cholangiopancreatography with endonasal biliary drainage was performed. On admission day 5, hemobilia with rupture of two intrahepatic artery pseudoaneurysms was observed on follow-up abdominal CT. Coil embolization of the pseudoaneurysms was conducted using percutaneous transhepatic biliary drainage. After several days, intrahepatic artery pseudoaneurysm rupture recurred and coil embolization through a percutaneous transhepatic biliary drainage tract was conducted after failure of embolization via the hepatic artery due to previous coiling. After the second coil embolization, a common bile duct stone was removed, and the patient presented no complications during 4 months of follow-up. We report a case of intrahepatic artery pseudoaneurysm rupture without prior history of intervention involving the hepatobiliary system that was successfully managed using coil embolization through percutaneous transhepatic biliary drainage.

담관 결석은 동통뿐만 아니라 황달이나 담도염 또는 췌장염 등을 유발할 수 있다. 결석에 대한 내시경적 제거가 실패할 경우 체외충격파쇄석술이 요구될 수 있는데, 이 논문은 담관 결석환자에 대한 체외충격파쇄석술 적용에 있어 보다 더 적절한 선택 기준을 정하는데 도움을 주기 위함이다. 총담관 결석 환자 중 기계적 쇄석술을 포함한 내시경적 제거에 실패한 46명이 체외충격파쇄석술을 받았다. 46명 모두 체외충격파쇄석술 전에 내시경적 유두괄약근 절개술을 받았으며, 경비담도배액관의 삽입이 이루어 졌다. 사용된 쇄석기는 초음파 유도하에 결석을 포착하는 시스템으로 spark-gap type이였다. 쇄석 후 추가적인 내시경적 제거술이 이루어 졌으며, 결석이 완전 제거된 경우는 89.1%(41/46)였으며, 자연 배출된 경우는 6.5%였다. 쇄석 후 결석제거율은 결석의 수(단일: 82.8%, 둘-셋: 100%, 넷 이상: 100%)와 크기(33 mm 미만: 92.9%, 33 mm 이상: 83.3%)에서는 큰 차이가 없었으나, 결석들의 장축 길이 합과 결석이 위치하지 않는 부분의 총담관 길이 합을 비교하였을 때 완전 제거된 경우와 그렇지 않은 경우의 비가 1:1.4와 1:1.1, 그리고 가장 큰 결석의 직경과 결석하방의 총담관 직경을 비교한 경우는 그 비가 1:0.9와 1:0.4로 의미 있는 차이를 보였다. 결론적으로, 결석의 수나 크기보다는 총담관 내에 분쇄된 결석이 충분히 움직여 바스켓으로 포획될 수 있는 공간이 있을 경우에 체외충격파쇄석술 적용이 상당히 유용하나 그렇지 않은 경우는 경피적 담도경을 이용한 제거가 유용할 것으로 보인다.

Bile pigment, bilirubin, and biliverdin concentrations may change as a results of biliary tract cancer (BTC) altering the mechanisms of radical oxidation and heme breakdown. We explored whether changes in bile pigment components could help distinguish BTC from benign biliary illness by evaluating alterations in patients with BTC. We collected bile fluid from 15 patients with a common bile duct stone (CBD group) and 63 individuals with BTC (BTC group). We examined the bile fluid's bilirubin, biliverdin reductase (BVR), heme oxygenase (HO-1), and bacterial taxonomic abundance. Serum bilirubin levels had no impact on the amounts of bile HO-1, BVR, or bilirubin. In comparison to the control group, the BTC group had considerably higher amounts of HO-1, BVR, and bilirubin in the bile. The areas under the curve for the receiver operating characteristic curve analyses of the BVR and HO-1 were 0.832 (p<0.001) and 0.891 (p<0.001), respectively. Firmicutes was the most prevalent phylum in both CBD and BTC, according to a taxonomic abundance analysis, however the Firmicutes/Bacteroidetes ratio was substantially greater in the BTC group than in the CBD group. The findings of this study showed that, regardless of the existence of obstructive jaundice, biliary carcinogenesis impacts heme degradation and bile pigmentation, and that the bile pigment components HO-1, BVR, and bilirubin in bile fluid have a diagnostic significance in BTC. In tissue biopsies for the diagnosis of BTC, particularly for distinguishing BTC from benign biliary strictures, bile pigment components can be used as additional biomarkers.

목적 : 총담관 확장을 유발하는 원인 중 결석과 종양을 제외한 여러 원인을 평가하는데 있어서 MRCP의 진단적 유용성을 알아보고자 하였다. 대상 및 방법 : ERCP와 MRCP를 모두 시행받은 환자 26명 (남:여=15:11, 평균연령 62세)을 대상으로 하였으며, 이들 중 12명은 역동적 MRCP를, 10명은 조영증강 MRI를 추가로 시행하였다. 총담관, 간내 담도, 췌관 등의 확장 정도, 간내 담도 결석, 췌장 가성낭종, 유두부의 부종이나 결절성 종대 등을 관찰하였다. 총담관은 T2-강조 관상영상에서 담낭절제술을 받지 않은 경우 7 mm 이상, 절제술을 받은 경우 10 mm 이상을 비정상적인 확장으로 판정하였다. 결과 : 담낭절제술을 받지 않은 환자의 총담관 평균 직경은 12.7mm(n=21, 9-19 mm)였고, 절제술을 받은 환자의 평균 직경은 13.0 mm(n=5, 10-15mm)였다(p〉0.05). MRCP에서 담관염 11명(42.3%), 만성 췌장염 8명(30.8%), 원위부 총담관 협착 6명(23.1%), 팽대부 주위 게실 3명(11.5%), Vater 팽대부 협착, 오디 괄약근 기능장애, 췌장 두부의 국소적 췌장염이 각각 2명 (7.7%), 유두염, 췌장 두부 가성낭종에 의한 총담관 확장, 총담관 내 회충이 각각 1명(3.8%) 있었다. 췌관의 확장은 10명(38.5%)에서 보였고, 십이지장 게실은 3명(11.5%)에서 관찰되었다. 역동적 MRCP(n=12)에서 2명(16.7%)은 일반 MRCP에서 보이지 않던 원위부 총담관이 관찰되었고, 조영증강 MRI를 시행한 10명 중 1명 (10.0%)만이 유두염의 소견을 보였다. 결론 : 비결석, 비종양성 총담관 확장의 원인을 찾는데 있어서 MRCP는 총담관 원위부 협착 및 만성 췌장염, 역동적 MRCP를 이용한 생리적 총담관의 확장, 조영증강 MRI 를 통한 담관염 및 담관 외 병소의 발견 등에 있어서 도움이 되는 것으로 생각된다.

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.

Fascioliasis is a zoonotic infection caused by Fasciola hepatica or Fasciola gigantica. We report an 87-year-old Korean male patient with postprandial abdominal pain and discomfort due to F. hepatica infection who was diagnosed and managed by endoscopic retrograde cholangiopancreatography (ERCP) with extraction of 2 worms. At his first visit to the hospital, a gallbladder stone was suspected. CT and magnetic retrograde cholangiopancreatography (MRCP) showed an intraductal mass in the common bile duct (CBD) without proximal duct dilatation. Based on radiological findings, the presumed diagnosis was intraductal cholangiocarcinoma. However, in ERCP which was performed for biliary decompression and tissue diagnosis, movable materials were detected in the CBD. Using a basket, 2 living leaf-like parasites were removed. The worms were morphologically compatible with F. hepatica. To rule out the possibility of the worms to be another morphologically close species, in particular F. gigantica, 1 specimen was processed for genetic analysis of its ITS-1 region. The results showed that the present worms were genetically identical (100%) with F. hepatica but different from F. gigantica.
