Primary neuroendocrine tumors originating from the extrahepatic bile duct are rare. Among these tumors, large cell neuroendocrine carcinomas (NECs) are extremely rare. A 59-year-old man was admitted to Sanggye Paik Hospital with jaundice that started 10 days previously. He had a history of laparoscopic cholecystectomy, which he had undergone 12 years previously due to chronic calculous cholecystitis. Laboratory data showed abnormally elevated levels of total bilirubin 15.3 mg/dL (normal 0.2-1.2 mg/dL), AST 200 IU (normal 0-40 IU), ALT 390 IU (normal 0-40 IU), and gamma-glutamyl transferase 1,288 U/L (normal 0-60 U/L). Serum CEA was normal, but CA 19-9 was elevated 5,863 U/mL (normal 0-37 U/mL). Abdominal CT revealed a 4.5 cm sized mass involving the common bile duct and liver hilum and dilatation of both intrahepatic ducts. Percutaneous transhepatic drainage in the left hepatic duct was performed for preoperative biliary drainage. The patient underwent radical common bile duct and Roux-en-Y hepaticojejunostomy for histopathological diagnosis and surgical excision. On histopathological examination, the tumor exhibited large cell NEC (mitotic index >20/10 high-power field, Ki-67 index >20%, CD56 [+], synaptophysin [+], chromogranin [+]). Adjuvant concurrent chemotherapy and radiotherapy were started because the tumor had invaded the proximal resection margin. No recurrence was detected at 10 months by follow-up CT.

Choledochal cyst is a congenital dilatation of the bile duct. Intrahepatic bile duct dilatation of type IVa by Todani's classification at the time of diagnosis resolved spontaneously after cyst excision and hepaticojejunostomy in many cases. It should be distinguished from the true cystic dilatation of the intrahepatic ducts, which tends to persist, albeit after some regression. We therefore studied postoperative intrahepatic duct dilatation changes in choledochal cyst. A total of seventy-six choledochal cysts were managed at the Division of Pediatric Surgery, Department of Surgery, Samsung Medical Center from May 1995 to December 2005. The ratio of males to females was 1:2.8. Preoperative radiologic diagnosis by Todani's classification was Type I (n=52, 68.4 %), II (n=1, 1.3 %), IVa (n=23, 30.3 %). Among fifty-five patients with intrahepatic bile duct dilatation we were able to follow up forty-eight by ultrasonography. Twenty-two patients were type IVa, and twenty-six patients were type I and showed intrahepatic duct dilatation. Mean follow-up duration was 35.3 months (9~105 months). Complete regression of dilated intrahepatic duct was observed in fifteen patients of type IVa and twenty-four patients of type I. Incomplete regression of dilated intrahepatic duct was observed in six patients in type IVa and two patients in type I. Only one patient in type IVa showed no change in ductal dilatation during a follow-up period of 15 months. We conclude that true type IVa is much less frequent than what was diagnosed preoperatively by imaging study. Therefore in type IVa patients who are diagnosed preoperatively the decision to perform liver resection should be carefully considered. Postoperative long term follow up of choledochal cyst with intrahepatic bile duct dilation is needed.

Biliary atresia (BA) is an uncommon neonatal surgical disease that has a fatal outcome if not properly treated. The survival rates of the patients with native liver after Kasai's operation in countries outside Japan are not so good. We reviewed the results of 22 cases of biliary atresia treated in Kosin University Hospital between October 1987 and March 2001. There were 13 males and 9 females aged from 21 to 106 days (mean 52 days). There were 3 cases of Type I (13.6%), and 3 of Type II (13.6%), and 16 Type III (72.7%). The operative methods were resection of the common bile duct remnant and cyst followed by Roux-en-Y hepaticojejunostomy in 3 cases for Type I BA; Kasai I in 15 cases, Kasai II in 1 case, and Ueda's operation in 3 cases for Types II and III BA. There was no death within the first 30 days after operation. We were able to follow 21 of the 22 patients (95.4%) for more than 5 years. The actual 5 year survival rate (YSR) was 40.9%. One Type I case received a living-related liver transplantation at 6 years of age because of the multiple intrahepatic stones and liver cirrhosis. Five YSR after biliostomy group (Kasai II and Ueda op.) was 75 % (3/4) while that of Kasai I was 20% (3/15). One case had no bile duct in the resected fibrotic plaque on microscopic review and died 8 months after Kasai I operation, would have been a strong candidate for early liver transplantation. From the above result, our conclusions are as follows; (1) early liver transplantation should be considered for cases of no bile duct after pathologic examination of the resected specimen, (2) measures to prevent postoperative cholangitis and prevention of postoperative liver cirrhosis are needed, (3) liver transplantation program should be available for failed cases.

담낭암은 진행된 상태에서 발견되었을 경우 예후가 매우 불량한 암으로 전신항암화학요법으로 치료를 하게 되나 일반적으로 고식적인 역할에 그치는 경우가 대부분이다. 본 증례는 원위부 림프절 전이가 있어서 수술적 절제가 불가능한 담낭암 환자에서 gemcitabine과 cisplatin을 병합한 전신항암화학요법으로 여섯 주기 치료 후 부분 관해를 얻어서 확대 담낭절제술이 가능하였던 증례로 매우 드문 증례를 경험하였기에 보고하는 바이다. 담낭암에서 수술 전 항암화학요법의 효과는 아직까지 확립되어 있지 않으나, 최근 양호한 종양 반응률과 종양 억제율을 보이는 항암화학요법이 개발됨에 따라서 그 가능성이 기대되고 있다.

본 조사 결과는 32개 병원의 39명의 회원에 의해 수술받은 환자 348명의 기록과 회원 37명의 설문 응답자를 분석한 것으로 많은 수의 기록지가 내용이 불충분하거나 일치되지 않은 기술로 인해 자료로서의 한계가 있었다. 특히 췌담관합류 이상에 대한 기록 중 약 절반이 미상으로 기록된 것에서 알 수 있드시 자료가 매우 미흡하였고, 담관낭종의 유형을 정하는 것 예후 인자 및 산 전 진단된 담관낭종의 수술 적기등에 대하여도 회원마다 견해 차이가 있으나 심도있는 토론이 이루어지지 않았다. 따라서 이 결과를 외국의 통계 분석과 비교하는 것 보다는 회원들의 향 후 진료와 연구에 참고가 될 수 있다는 것에 의미를 두고자 하며, 회원들이 동일한 등록지를 작성하는 전향적 연구로 우리나라 담관낭종에 대한 분류, 췌담관 합류이상, 예후 인자들에 대한 재 논의의 출발점이 되기를 기대한다.
