To review our 34-year experience with 574 consecutive resections for perihilar cholangiocarcinoma and to evaluate the progress made in surgical treatment of this disease.Few studies have reported improved outcomes cholangiocarcinoma; therefore, it is still unclear whether intractable disease has progressed.Between April 1977 December 2010, a total 754 patients were treated, whom (76.1%) underwent resection. The medical records these resected retrospectively reviewed.The incidence major...

In Brief Objective: To outline our experience with hepatectomy simultaneous resection of the portal vein and hepatic artery for advanced perihilar cholangiocarcinoma, to discuss clinical significance this challenging hepatectomy. Summary Background Data: Only a few authors reported negative results surgery in very limited number patients. Methods: We retrospectively reviewed medical records 50 patients cholangiocarcinoma who underwent (left trisectionectomy 26, left 23, right 1)...

Abstract Background It is difficult to predict hepatic functional reserve accurately before major hepatectomy. The aim of this study was analyse the usefulness future liver remnant plasma clearance rate indocyanine green (ICGK-F, calculated as (ICGK) × proportion remnant) in predicting death after Methods Data on ICGK and ICGK-F were collected prospectively analysed retrospectively for 274 patients who underwent right hepatectomy, trisectionectomy or left biliary cancer between 1991 2008....

To outline our experience with hepatopancreatoduodenectomy (HPD) as a treatment for cholangiocarcinoma and to appraise the clinical significance of this challenging procedure.Cholangiocarcinomas often exhibit an extensive ductal spread invading from hepatic hilus lower bile duct, such tumors can be completely resected only by HPD. Early experiences HPD were associated high mortality morbidity, leading underestimation survival benefit HPD.We retrospectively reviewed medical records 85...

Abstract Objective To review our surgical experience with hilar cholangiocarcinoma in the “new era.” Methods The medical records of 428 patients who underwent treatment between 2001 and 2008 at First Department Surgery, Nagoya University Hospital, were retrospectively reviewed. Results Of patients, 298 (70%) resection (R0, n = 220; R1, 70; R2, 8). Portal vein was performed 111 (37%) hepatic artery 53 (18%) patients. Several different types postoperative complications occurred a total 129...

Abstract Background The aim of the study was to clarify incidence, risk factors and treatment percutaneous transhepatic biliary drainage (PTBD) catheter tract recurrence in patients with resected cholangiocarcinoma. Methods medical records 445 perihilar distal cholangiocarcinoma who underwent resection following PTBD were reviewed retrospectively. Results detected 23 (5·2 per cent). mean(s.d.) interval between surgery onset 14·4(13·8) months. On multivariable analysis, duration (60 days or...

To review our experience with cholangiocarcinoma superficial spread, to clarify its clinical features, and discuss treatment strategies.Most of the previous reports on spread were case reports. Little is known about this type cholangiocarcinoma.The medical records 471 patients who underwent resection (351 perihilar 120 distal cancers) retrospectively reviewed, focusing which was defined as noninvasive cancer extension more than 20 mm.Superficial found in 69 (14.6%) patients, length 54 +/- 19...

To analyze lymph node status in resected perihilar cholangiocarcinoma, to clarify which index (ie, location, number, or ratio of involved nodes) is better for staging, and determine the minimum requirements examination.In TNM classification number nodes not considered nodal staging. The requirement histologic examination arbitrary.This study 320 patients with cholangiocarcinoma who underwent resection from January 2000 December 2009 at Nagoya University Hospital. relationship between patient...

<i>Backgrounds:</i> Portal vein embolization (PVE) has been widely applied before extended hepatectomy; however, its clinical utility for patients with biliary cancer not fully addressed. <i>Methods:</i> Between 1991 and 2010, 494 cholangiocarcinoma (n = 353) or gallbladder 141) underwent PVE hepatectomy. was performed by a transhepatic ipsilateral approach using fibrin glue absolute ethanol steel coils. Surgical outcomes of this cohort were retrospectively reviewed....

Bismuth type IV perihilar cholangiocarcinoma has traditionally been categorized as unresectable disease. The aim of this study was to review experience with a resection-based strategy in patients who have cholangiocarcinoma.Medical records consecutive diagnosis between 2006 and 2015 were reviewed retrospectively. Primary outcomes assessed surgical results long-term survival.Of the 332 tumour, 216 (65·1 per cent) underwent resection. Left hepatic trisectionectomy most common procedure (112...

To review our experiences with left-sided hepatectomy for perihilar cholangiocarcinoma, to compare left trisectionectomy, and evaluate the clinical significance of trisectionectomy from viewpoint surgical oncology.Only 4 large case series have been reported on only a few patients diagnosed cholangiocarcinoma. Therefore, oncologic advantage compared cholangiocarcinoma is still unclear.This study involved 201 who underwent (86 trisectionectomies 115 hepatectomies). Surgical outcome survival...

To clarify the value of resection gallbladder cancer involving extrahepatic bile duct.: Several recent studies have proven that jaundice and biliary involvement are independent predictors a poor outcome. Only few authors recommend such advanced disease.One hundred patients with pT3/4, pN0/1, M0 disease were subjects this study. Mortality long-term outcome analyzed using prospectively collected database.The only factor associated mortality in univariate multivariate analyses was...

Hepatectomy of segments 4a and 5 (S4a+5) is the recommended treatment for pT2 gallbladder cancer. However, bed resection also occasionally used. Using nationwide data from Japanese Biliary Tract Cancer Registry a questionnaire survey, we retrospectively compared these 2 methods treatment.The study involved 85 patients with pT2, pN0 cancer (55 treated resection, 30, S4a+5 hepatectomy). The prognosis mode tumor recurrence following were analyzed retrospectively, overall survival as...
