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. A nationwide survey on choledochal cyst was undertaken among 39 members of the Korean Association of Pediatric Surgeons. The members were required to complete a questionnaire and the case registration form for each patient during the five year period of 1997 to 2001. Three hundred and forty eight patients were registered from 32 institutions. The average number of patients per surgeon was one to two every year. The male to female ratio was 1:3.4. The age of patients on diagnosis was $49.0{\pm}44.4$ months. The geographic distribution was 34.8% in Seoul and Kyoungki-do, 33.3% in Kyoungsang-do, 17.9% in Cholla-do, and 8.5% in Choongchung-do, in order of frequency. The three common clinical presentations were abdominal pain (63.8%), vomiting (35.3%), and jaundice (29.1%). Only seven patients (2%) presented with classic triad, and 25 patients were diagnosed by antenatal ultrasonographic examination. According to the Todani Classification, 238 patients (7l.3%) were type 1, 3 (0.9%) type 11, and 93 (27.8%) type IV. At the time of the operation, three important associated conditions were choledocholithiasis in 45 patients (15.1%), liver fibrosis (Grade 1-4) in 35, and previous operative procedure for biliary diseases in 10. Associated anomalies were observed in 13 patients (3.8%). Three hundred thirty nine (98.8%) of 343 lesions were treated by Cyst excision and Roux-Y hepaticoiejunostomy. One hundred seventy-six patients had an anomalous arrangement of the pancreatobiliary ductal system (APBD): APBD was not in 92 patients, biliary duct joined to the pancreatic duct in 51, and pancreatic duct joined to the biliary duct in 26. There were 8.5% early, and 7.7% late phase operative complications. The major complications were bleeding, anastomotic leakage, and acute pancreatitis. The combination of acute abdomen and choledochal cyst may suggest spontaneous rupture. Because of the development of late intrahepatic bile duct stones, long term follow up after cyst excision and hepaticojejunostomy is required. The optimal time of surgical intervention should also be considered in the situation of routine use of antenatal ultrasonographic examination. This is the first review of the choledochal cyst in Korea and provides baseline data for future comparisons.

In order to get cost reduction in the turning machining field, manpower and extra expenses are reduced. To get an optimum cutting condition, it highly tends to depend on a lot of tests according to individual field experience. So it is necessary for change of the flexible cutting conditions in industrial site, because the society becomes high technology gradually. This study presents and effective method to get optimum cutting condition using Taguchi method that is most commonly used a design of experimental method. Therefore, this study can get an optimum cutting condition at minimum of test according to make cutting plans through using the minimum design of experiment.
