Purpose of this paper is to extend help for clinical application in balloon cholangiography on patients who have undergone endoscopic sphincterotomy, impacted stones of intrahepatic duct, and missed bile duct because of other diseases in operating endoscopic retrograde cholangiopancreatography. This study was done for the patients who had clinical signs of biliary diseases from January to December In 1996. We studied 45 patients who had endoscopic sphincterotomy, re-examination after interventional treatment of the endoscopic retrograde cholangiopancreatography, and uncertain diagnosis due to common bile duct and intrahepatic duct those are not filled with contrast media. Balloon cholangiography was performed in case of uncertain diagnosis while operating endoscopic retrograde cholangiopancreatography. First of all, we insert balloon catheter Into the working channel of treatment jejunofiberscope and remove treatment Jejunofiberscope after ballooning, and lastly take biliary tract X-ray after Injection and changing position of patient. The results of this study were as follows. (1) In classification of diseases, stones of gall bladder, those of common bile duct, and those of intrahepatic duct were 30 cases, fistula was 1 case. (2) In total cases of 45, only diagnosis were 25 cases, interventional treatment were 20 cases. (3) In case of interventional treatment, endoscopic sphincterotomy and endoscopic nasobiliary drainage, and stone removal were about the same, 7, 7, 6 respectively. Balloon cholangiography will be useful to prevent patients from having repeated and unnecessary studies for the cases above explained. It is considered that this study will be useful for clinical application in terms of reducing medical expenses, pain while examination, and consultation hours.

An 89-year-old man was referred to our hospital for treatment of hepatolithiasis causing recurrent cholangitis. He had undergone a prior Whipple procedure. Computed tomography demonstrated left-sided hepatolithiasis. First, we conducted peroral direct cholangioscopy (PDCS) using an ultraslim endoscope. Although PDCS was successfully conducted, it was unsuccessful in removing all the stones. The stones located in the B2 segment were difficult to remove because the endoscope could not be inserted deeply into this segment due to the small size of the intrahepatic bile duct. Next, we substituted the endoscope with an upper gastrointestinal endoscope. After positioning the endoscope, the SpyGlass digital system (SPY-DS) was successfully inserted deep into the B2 segment. Upon visualizing the residual stones, we conducted SPY-DS-guided electrohydraulic lithotripsy. The stones were disintegrated and completely removed. In cases of PDCS failure, a treatment strategy using the SPY-DS can be considered for patients with hepatolithiasis after a Whipple procedure.

A 6-year-old, intact female mixed dog was referred to Veterinary Medical Teaching Hospital of Gyeongsang National University due to vomiting, anorexia, depression of 1 month's duration. On abdominal radiography, numerous irregularly marginated mineralized branching structures were present within the liver. On ultrasonography, irregular hyperechoic spots with an strong acoustic shadow was identified, but evidence of ductal dilatation was absent. Based on radiography and ultrasonography, intrahepatic gallstones were diagnosed incidentally.

Choledochal cyst is a dilation that encloses the intrahepatic or both extra- and intrahepatic portions of the biliary ducts. Postnatally, ultrasonography is the initial diagnostic modality of choice, allowing for precise measurements of intra- or extrahepatic duct dilatation and identification of stones and sludge. Symptoms depend on the age at presentation. Common bile duct malformations should be considered as a differential diagnosis of a cystic mass regardless of the cyst's size or patient's age, especially in children presenting with abdominal pain, jaundice, and palpable mass. To the best of our knowledge, we report the largest choledochal cyst in infancy.

Purpose: The aim of this study was to describe our treatment experiences with patients who had acute abdomen (AA) with common bile duct (CBD) dilatation. Methods: The treatment outcomes in children with AA and CBD dilatation were retrospectively reviewed. According to the shape of the intrahepatic bile ducts on ultrasonography (US), the origin of the pain was estimated as choledochal cyst (CC) complication or choledocholithiasis in normal CBD. Patients with complicated CC underwent surgery, and patients with choledocholithiasis in a normal appearing CBD underwent symptomatic treatment initially. Results: Of the 34 patients, 30 (88.2%) were female. The mean age of the patients was $6.4{\pm}4.9$ (range, 0.8-17) years. Seventeen (50.0%) patients had CBD stones and 17 (50.0%) did not. Surgical treatment was performed in 20 (58.8%) patients, 2 of whom underwent preoperative stone removal with endoscopic retrograde cholangiopancreatography and an operation. Conservative treatment was applied in 12 (35.3%) patients (8 with and 4 without stones), 1 of whom developed symptom relapse and underwent an operation. Among the 8 patients with CBD stones, 4 (4/17, 23.5%) had complete resolution of the stones and recovery of the CBD diameter after conservative treatment. US findings of patients with stone showed a fusiform or cylindrical shape of the CBD in 14 (82.4%) patients. Conclusion: The presence of stones in the distal CBD and the US features of CBD dilatation may be helpful to diagnose and treat the causes of biliary dilatation. Conservative treatment can be considered as initial therapy in patients with uncomplicated CBD dilatation with stone.

Ascaris lumbricoides causes one of the most common soil-transmitted helminthiases globally. The worms mostly infect the human small intestine and elicit negligible or nonspecific symptoms, but there are reports of extraintestinal ectopic ascariasis. We describe a rare case of biliary ascariasis mistaken for biliary stent in a 72-year-old female patient with a history of liver resection. She visited our outpatient clinic complaining of right upper quadrant pain and fever for the past week. She had previously undergone left lateral sectionectomy for recurrent biliary and intrahepatic duct stones 2 years ago. Besides mildly elevated gamma-glutamyl transferase levels, her liver function tests were normal. Magnetic resonance cholangiopancreatography revealed a linear filling defect closely resembling an internal stent from the common bile duct to the right intrahepatic bile duct. A live female A. lumbricoides adult worm was removed by endoscopic retrograde cholangiopancreatography (ERCP). Despite a significant decrease of the ascariasis prevalence in Korea, cases of biliary ascariasis are still occasionally reported. In this study, a additional case of biliary ascariasis, which was radiologically misdiagnosed as the biliary stent, was described in a hepatic resection patient by the worm recovery with ERCP in Korea.

목적 본 연구는 담낭절제술 후 보상적 총담관 확장의 빈도와 정도를 조사하고, 담낭절제술과 common bile duct (이하 CBD) 확장 사이의 시간을 평가하고, 폐쇄성 CBD 확장을 암시하는 잠재적으로 유용한 CT 소견을 식별하는 것을 목표로 한다. 대상과 방법 2009년에서 2011년 사이에 단일 센터에서 담낭절제술 전후에 여러 차례 CT 스캔을 받은 담도 폐쇄가 없는 121명의 환자를 대상으로 한 후향적 연구를 진행하였다. 또한 담낭절제술 후 CBD 결석 또는 팽대부 종양으로 인해 초기에 연구에서 제외되었던 11명의 환자의 임상 및 CT 소견을 조사하여 폐쇄성 및 비폐쇄성 CBD 확장의 특징을 확인하였다. 결과 121명의 환자의 평균(표준편차) 단축 최대 CBD 직경은 담낭절제술 전 축면에서 5.6(± 1.9) mm였지만 담낭절제술 후 7.9 (± 2.6) mm로 증가했다(p < 0.001). 담낭절제술 전 축성 CBD 직경이 8 mm 미만인 106명의 환자 중 39명(36.8%)이 담낭절제술 후 ≥ 8 mm의 CBD 확장을 보였다. 장기(> 2년) 연속 추적 CT 스캔을 받은 17명의 환자 중 6명(35.3%)은 결국 모두 담낭 절제술 후 2년 이내에 축성 CBD 직경이 유의미하게(> 1.5배) 증가한 것으로 나타났다. 폐색 또는 관련 증상이 없는 121명의 환자 중 단 1명(0.1%)만이 담낭 절제술 후 intrahepatic duct (이하 IHD) 확장 > 3 mm를 보였던 반면, CBD 폐쇄가 있는 11명의 환자 모두 복통과 비정상 검사실 지수가 있었고 81.8% (9/11)가 IHD 및 CBD의 상당한 확장을 보였다. 결론 보상적 비폐쇄성 CBD 확장은 일반적으로 폐쇄성 확장과 비슷한 정도로 담낭절제술 후에 발생한다. 그러나 담낭절제술 후 담관 폐색과 관련 증상이 있거나, 의미 있는 IHD 확장 또는 2-3년 후 추가적인 CBD 확장이 발생하는 경우 CBD 폐쇄를 의심해야 한다.

담즙산 분비 저하 및 콜레스테롤의 과도한 분비는 담석 형성의 주된 원인으로 담즙내의 담즙산과 콜레스테롤 및 그 전구 물질인 스테롤의 상대적인 농도는 담즙 성분의 이상을 알아보기 위한 중요한 지표로 알려져 있다. 이에 본 연구에서는 염기를 이용한 가수 분해와 pH 14와 1에서 두 번의 액체-액체 추출을 거친 후, $MSTFA/NH_4I$ 혼합액으로 유도체화 시키는 전처리 방법과 GC/MS를 이용한 새로운 분석 방법을 설정, 담즙산과 스테롤 그리고 콜레스테롤의 동시 분석을 시도하였다. 그 결고 회수율은 73.56-96.95% 이었고 within-a-day 및 day-to-day 분석의 RSD 값은 각각 1.72-13.79%, 0.68-14.10% 이었으며, 이 방법을 간내 담석증 환자에 적용하여 담즙과 담석내에 존재하는 7종의 스테롤과 5종의 담즙산, 그리고 콜레스테롤의 농도 및 그들간의 상대적인 농도 분포를 측정한 결과 담즙고 담석에서 현저히 다른 차이를 보였다.
