Three cytology examinations of the patient's bile could not establish that the tumor was an adenocarcinoma. However, adenocarcinoma was suspected due to the hypervascularity shown on contrast-enhanced computed tomography. Cholecystectomy and extrahepatic bile duct resection with D2 lymph node dissection was performed. The pathological study revealed it to be CDC. Her postoperative course has been uneventful and without recurrence for 21 months.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>DISCUSSION:<\/jats:title>\n                    <jats:p>At their first medical examination, many CDC patients are found to have such advanced spread of the cancer to adjacent organs that an extended operation might be necessary. As in our case, better patient outcome results when no lymph node or remote metastasis is present.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION:<\/jats:title>\n                    <jats:p>Diagnosing CDC as early as possible contributes to curative resections and favorable patient outcomes and also allows surgeons to recommend a mini-invasive procedure to their patients rather than extended resection including that of adjacent organs.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1016\/j.ijscr.2014.04.022","type":"journal-article","created":{"date-parts":[[2014,4,30]],"date-time":"2014-04-30T13:34:49Z","timestamp":1398864889000},"page":"354-357","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Preoperative diagnosis of an asymptomatic cancer restricted to the cystic duct"],"prefix":"10.1097","volume":"5","author":[{"given":"Shuji","family":"Komori","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juji","family":"Tsuchiya","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Iwao","family":"Kumazawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hajime","family":"Kawagoe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kimitoshi","family":"Nishio","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuki","family":"Misao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"R1-3-20260114","doi-asserted-by":"crossref","first-page":"183","DOI":"10.1002\/bjs.18003915414","article-title":"Carcinoma of the cystic duct","volume":"39","author":"Farrar","year":"1951","journal-title":"Br J Surg"},{"key":"R2-3-20260114","doi-asserted-by":"crossref","first-page":"1218","DOI":"10.1002\/1097-0142(1955)8:6<1218::AID-CNCR2820080619>3.0.CO;2-#","article-title":"Extrahepatic biliary-tract cancer","volume":"8","author":"Glenn","year":"1955","journal-title":"Cancer"},{"key":"R3-3-20260114","first-page":"1","article-title":"Carcinoma of the gall-bladder.
