Utility of modified pancreaticoduodenectomy (Hi-cut PD) for middle-third cholangiocarcinoma: an alternative to hepatopancreaticoduodenectomy. HPB (Oxford) 2024; 26:530-540. [PMID: 38216429 DOI: 10.1016/j.hpb.2023.12.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Revised: 11/05/2023] [Accepted: 12/18/2023] [Indexed: 01/14/2024]
Abstract
BACKGROUND The standard procedure for middle-third cholangiocarcinoma (MCC) is pancreaticoduodenectomy (PD); hepatopancreaticoduodenectomy (HPD) is often performed despite its high risk. There is no clear selection guidance for these procedures. METHODS Patients with MCC who underwent HPD or PD were retrospectively evaluated. The conventional PD was modified (mPD) to transect the bile duct beyond or close to the cranial level of the portal bifurcation. RESULTS The mPD group (n = 55) was characterized by older age, shorter operation time, less blood loss, and less frequent complications than were observed in the HPD group (n = 34). The median grossly tumor-free margin of the proximal bile duct (GM) was 13 mm vs 20 mm (P = 0.006). Overall survival did not differ significantly between groups (48% vs 53% at 5 years, P = 0.399). Multivariate analysis identified positive surgical margin as a sole independent prognostic factor (hazard ratio, 1.89; P = 0.043), which was statistically associated with GM length. Five-year survival for mPD patients with GM ≥15 mm was significantly better than that for those who had GM <15 mm (69% vs 33%, P = 0.011) and comparable to that of HPD patients (53%, P = 0.450). CONCLUSION The mPD may be recommended in patients with MCC, provided that GM ≥15 mm is expected from the preoperative radiological imaging. Otherwise, HPD should be considered.

Safety and feasibility of laparoscopic radical resection for bismuth types III and IV hilar cholangiocarcinoma: a single-center experience from China. Front Oncol 2023; 13:1280513. [PMID: 38188306 PMCID: PMC10766688 DOI: 10.3389/fonc.2023.1280513] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2023] [Accepted: 11/29/2023] [Indexed: 01/09/2024] Open
Abstract
Background Surgery represents the only cure for hilar cholangiocarcinoma (HC). However, laparoscopic radical resection remains technically challenging owing to the complex anatomy and reconstruction required during surgery. Therefore, reports on laparoscopic surgery (LS) for HC, especially for types III and IV, are limited. This study aimed to evaluate the safety and feasibility of laparoscopic radical surgery for Bismuth types III and IV HC. Methods The data of 16 patients who underwent LS and 9 who underwent open surgery (OS) for Bismuth types III and IV HC at Mianyang Central Hospital, School of Medicine, University of Electronic Science and Technology of China, between December 2017 and January 2022 were analyzed. Basic patient information, Bismuth-Corlette type, AJCC staging, postoperative complications, pathological findings, and follow-up results were evaluated. Results Sixteen patients underwent LS and 9 underwent OS for HC. According to the preoperative imaging data, there were four cases of Bismuth type IIIa, eight of type IIIb, and four of type IV in the LS group and two of type IIIa, four of type IIIb, and three of type IV in the OS group (P>0.05). There were no significant differences in age, sex, ASA score, comorbidity, preoperative percutaneous transhepatic biliary drainage rate, history of abdominal surgery, or preoperative laboratory tests between the two groups (P>0.05). Although the mean operative time and mean intraoperative blood loss were higher in the LS group than in OS group, the differences were not statistically significant (P=0.121 and P=0.115, respectively). Four patients (25%) in the LS group and two (22.2%) in the OS group experienced postoperative complications (P>0.05). No significant differences were observed in other surgical outcomes and pathologic findings between the two groups. Regarding the tumor recurrence rate, there was no difference between the groups (P>0.05) during the follow-up period (23.9 ± 13.3 months vs. 17.8 ± 12.3 months, P=0.240). Conclusion Laparoscopic radical resection of Bismuth types III and IV HC remains challenging, and extremely delicate surgical skills are required when performing extended hemihepatectomy followed by complex bilioenteric reconstructions. However, this procedure is generally safe and feasible for hepatobiliary surgeons with extensive laparoscopy experience.

The role of subspecialized radiologist reviews in preoperative conference for hepato-pancreato-biliary disease. Eur J Radiol 2023; 169:111183. [PMID: 37944332 DOI: 10.1016/j.ejrad.2023.111183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 10/10/2023] [Accepted: 10/30/2023] [Indexed: 11/12/2023]
Abstract
PURPOSE To identify the role of subspecialized radiologists in preoperative conferences of radiologists and surgeons in the management of hepato-pancreato-biliary (HPB) diseases. METHODS We retrospectively evaluated the prospective data of 247 patients (mean age, 63.8 years; 173 men) who were referred for preoperative conferences (n = 258; 11 were discussed twice) for HPB disease between September 2021 and April 2022. Before each preoperative conference, subspecialized radiologists reviewed all available imaging studies and treatment plan information. After each conference, any change to the treatment plan was documented (major, minor, or none). Additional information provided by the radiologists was collected (significant, supplementary, or none). Uni- and multivariable analyses were performed to determine factors that resulted in a major change to the treatment plan. RESULTS Of the 258 reviewed cases, a major change was made to the treatment plan in 26 cases (10.1 %) and a minor change in 41 (15.9 %). Significant information was provided in 27 cases (10.5 %) and supplementary information in 72 (27.9 %). In the multivariable analysis, additional information about local tumor extent (odds ratio [OR], 6.3; 95 % confidence interval [CI], 2.1-19.5; p = 0.001) and distant metastasis detection (OR, 33.2; 95 % CI, 5.1-216.6; p < 0.001) was significantly associated with a major change. CONCLUSION The involvement of subspecialized radiologists in preoperative conferences resulted in major treatment plan changes in 10.1 % of the cases, primarily associated with the added information about local tumor extent and distant metastasis.

Screening for hilar biliary invasion in ampullary cancer patients. World J Gastrointest Endosc 2022; 14:536-546.

Abstract
BACKGROUND The treatment for ampullary cancer is pancreatoduodenectomy or local ampullectomy. However, effective methods for the preoperative investigation of hilar biliary invasion in ampullary cancer patients have not yet been identified.
AIM To determine the necessity of and an appropriate method for investigating hilar biliary invasion of ampullary cancer.
METHODS Among 43 ampullary cancer patients, 34 underwent endoscopic treatment (n = 9) or surgery (n = 25). The use of imaging findings (thickening and enhancement of the bile duct wall on contrast-enhanced computed tomography, irregularity on endoscopic retrograde cholangiography, thickening of the entire bile duct wall on intraductal ultrasonography (IDUS), and partial thickening of the bile duct wall on IDUS) and biliary biopsy results for diagnosing hilar biliary invasion of ampullary cancer was compared.
RESULTS Hilar invasion was not observed in every patient. Among the patients who did not undergo biliary stent insertion, the combination of partial thickening of the bile duct wall on IDUS and biliary biopsy results showed the highest accuracy (100%) for diagnosing hilar biliary invasion. However, each imaging method and biliary biopsy yielded some false-positive results.
CONCLUSION Although some false-positive results were obtained with each method, the combination of partial thickening of the bile duct wall on IDUS and biliary biopsy results was useful for diagnosing hilar biliary invasion of ampullary cancer. However, hilar invasion of ampullary cancer is rare; therefore, the investigation of hilar biliary invasion of ampullary cancer might be unnecessary.

Abstract
Endoscopic management for perihilar cholangiocarcinoma (PHCC) is evolving toward more accurate diagnosis and safer drainage. In imaging, it is important to diagnose the entire lesion using multidetector-row computed tomography to determine resectability and optimal surgical planning, followed by local diagnosis using endoscopic retrograde cholangiopancreatography. Video peroral cholangioscopy and probe-based confocal laser endomicroscopy have been newly introduced as diagnostic imaging methods and are being applied clinically. In transpapillary forceps biopsy for PHCC diagnosis, the location in the bile duct (for mapping biopsy) and the number of biopsy samples should be determined depending on resectability, the morphological type, and future surgical planning. Preoperative drainage has shifted from percutaneous transhepatic biliary drainage to endoscopic nasobiliary drainage given the possibility of seeding metastasis. In addition, considering potential patient discomfort from a nasal tube, the usefulness of the placement of a plastic stent above the papilla (inside stent) as a bridging therapy for surgery has been reported. For drainage of unresectable PHCC, the improved prognosis due to advances in chemotherapy has necessitated a strategy that accounts for reintervention. Thus, in addition to uncovered self-expandable metallic stents (SEMS), exchangeable slim fully covered SEMS and inside stents have started to be used. In addition to the conventional transpapillary approach, an endoscopic ultrasonography-guided approach has been introduced, and a combination of both methods has also been proposed. To improve the quality of life and prognosis of PHCC patients, endoscopists need to understand and be able to use the various methods of endoscopic management for PHCC.

Abstract
Background In extrahepatic bile duct (EHD) cancer, accurate assessment of resectability is essential for curative surgery, but pertinent guidelines from the perspectives of radiologists are yet to be developed. Purpose To investigate the performance of multiphasic CT in the assessment of longitudinal tumor extent, vascular invasion, and resectability of EHD cancer according to the Korean Society of Abdominal Radiology consensus recommendation and to evaluate the interreader agreement. Materials and Methods This retrospective study included patients with EHD cancer who underwent multiphasic CT examinations with section thickness of 3 mm or less before surgery from January 2016 to December 2018. Four abdominal radiologists independently evaluated the overall and biliary segment-wise longitudinal tumor extent, the presence of hepatic artery and/or portal vein invasion, and the resectability according to the Korean Society of Abdominal Radiology recommendations. The diagnostic performance was assessed with sensitivity, specificity, accuracy, and area under the receiver operating characteristic curve. Interreader agreement was determined using κ statistics. Results A total of 112 patients (mean age ± SD, 61 years ± 11; 73 men) were evaluated. The accuracy of the overall longitudinal tumor extent assessment ranged from 56.3% (63 of 112 patients) to 74.1% (83 of 112 patients). The sensitivity for detecting secondary confluence involvement (n = 62) was lower than that for the primary confluence or intrapancreatic duct (n = 115; 38.5%-75% vs 72.1%-96.3%, respectively). Vascular invasion (n = 17) had moderate sensitivity (28.6%-71.4%) and high specificity (77.5%-99.0%). For predicting negative-margin (R0) resection (n = 85), the sensitivity and specificity ranged from 71.8% to 96.5% and from 11.1% to 66.7%, respectively, and the areas under the receiver operating characteristic curve ranged from 0.69 to 0.80. Interreader agreements for tumor extent, vascular invasion, and resectability had κ values of 0.65-0.89, 0.21-0.64, and 0.35-0.56, respectively. Conclusion For the preoperative evaluation of extrahepatic bile duct cancer, the Korean Society of Abdominal Radiology consensus recommendation enabled systematic assessment of longitudinal tumor extent and vascular invasion with acceptable performance in predicting negative-margin resection with use of multiphasic CT and with fair to good interreader agreement. © RSNA, 2022 Online supplemental material is available for this article.

Abdom Radiol (NY) 2021; 46:1922-1930. [PMID: 33159559 DOI: 10.1007/s00261-020-02849-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Revised: 10/23/2020] [Accepted: 10/30/2020] [Indexed: 12/28/2022]
Abstract
OBJECTIVE To compare the diagnostic performance of three CT criteria and two signs in evaluating hepatic arterial invasion by hilar cholangiocarcinoma. METHODS In this study, we retrospectively reviewed the CT images of 85 patients with hilar cholangiocarcinoma. Modified Loyer's, Lu's, and Li's standards were used to evaluate hepatic arterial invasion by hilar cholangiocarcinoma with the reference of intraoperative findings and/or the postoperative pathological diagnosis. Arterial tortuosity and contact length were also evaluated. RESULTS Loyer's, Lu's, and Li's standards showed sensitivities of 91.7%, 90.3%, and 72.2%, specificities of 94.0%, 94.5%, and 95.6%, and accuracies of 93.3%, 93.3%, and 89.0%, respectively, in evaluating hepatic arterial invasion by hilar cholangiocarcinoma. Loyer's and Lu's standards and contact length performed better than Li's standard (P < 0.001). Arterial tortuosity performed worse than other criteria (P < 0.001). The CT criteria performed best in evaluating proper hepatic arterial invasion compared with the left and right hepatic artery. When the cut-off contact length of 6.73 mm was combined with Loyer's standard, 4 false-negative cases could be avoided. CONCLUSIONS Loyer's and Lu's standards and the contact length performed best in evaluating hepatic arterial invasion by hilar cholangiocarcinoma on preoperative CT images, particularly in assessing the proper hepatic artery. Arterial tortuosity could serve as an important supplement. The combination of the contact length and Loyer's standard could improve the diagnostic performance.

Abstract
Cholangiocarcinoma (CCC) is the most aggressive malignant tumor of the biliary tract. Perihilar CCC (pCCC) is the most common CCC and is burdened by a complicated diagnostic iter and its anatomical location makes surgical approach burden by poor results. Besides its clinical presentation, a multimodal diagnostic approach should be carried on by a tertiary specialized center to avoid miss-diagnosis. Preoperative staging must consider the extent of liver resection to avoid post-surgical hepatic failure. During staging iter, magnetic resonance can obtain satisfactory cholangiographic images, while invasive techniques should be used if bile duct samples are needed. Consistently, to improve diagnostic potential, bile duct drainage is not necessary in jaundice, while it is indicated in refractory cholangitis or when liver hypertrophy is needed. Once resecability criteria are identified, the extent of liver resection is secondary to the longitudinal spread of CCC. While in the past type IV pCCC was not considered resectable, some authors reported good results after their treatment. Conversely, in selected unresectable cases, liver transplantation could be a valuable option. Adjuvant chemotherapy is the standard of care for resected patients, while neoadjuvant approach has growing evidences. If curative resection is not achieved, radiotherapy can be added to chemotherapy. This multistep curative iter must be carried on in specialized centers. Hence, the aim of this review is to highlight the main steps and pitfalls of the diagnostic and therapeutic approach to pCCC with a peculiar attention to type IV pCCC.

Abstract
There has been enormous progress in the surgical treatment of biliary tract cancers in the past 50 years. In preoperative management, biliary drainage methods have changed from percutaneous transhepatic biliary drainage to endoscopic nasobiliary drainage, while the advent of multidetector-row computed tomography in imaging diagnostics now enables visualization of three-dimensional anatomy, extent of cancer progression, and hepatic segment volume. Portal vein embolization has also greatly improved the safety of extended hepatectomy, and indication of extended hepatectomy can now be objectively determined with a combination of the indocyanine green test and computed tomography volumetry. In terms of surgery, combined resection and reconstruction of the portal vein and/or hepatic artery can now be safely carried out at specialized centers. Further, long-term survival can be attained with combined vascular resection if R0 resection can be achieved, even in locally advanced cancer. Hepatopancreatoduodenectomy, combined major hepatectomy with pancreatoduodenectomy, should be aggressively carried out for laterally advanced cholangiocarcinoma, whereas its indication for advanced gallbladder cancer should be carefully evaluated. Japanese surgeons have made a significant contribution to the progression of extended surgeries such as combined vascular resection and hepatopancreatoduodenectomy for biliary tract cancer.

Abstract
BACKGROUND Right hepatectomy with caudate lobectomy (RHx) is considered an appropriate procedure for Bismuth type I/II perihilar cholangiocarcinoma in terms of its anatomical and oncological aspect. However, validity of left hepatectomy with caudate lobectomy (LHx) concomitant with arterial resection and reconstruction (AR) is not fully evaluated. METHODS The patients who underwent surgical resection for Bismuth type I/II perihilar cholangiocarcinoma between 2002 and 2013 were studied. The standard procedure for Bismuth type I/II cholangiocarcinoma in the institute was RHx, while in patients who had insufficient functional reserve of the left liver, LHx was selected, irrespective of the necessity of AR. The clinicopathologic and perioperative outcomes after LHx + AR were compared with those after RHx. RESULTS The surgical procedures comprised LHx + AR in 12 and RHx in 24. The left liver volume and left liver functional reserve were significantly lower with LHx + AR than with RHx (left liver volume: 28.0 vs. 33.7%, p = 0.026; estimated indocyanine green clearance of the left liver: 0.036 vs. 0.046, p < 0.001). The rate of surgical morbidity was almost identical between the two procedures. No arterial reconstruction-related complications occurred. The overall 3- and 5-year survival rates and median survival time were 66.7%, 41.7% and 44 months for LHx + AR and 70.8%, 49.0% and 57 months for RHx (p = 0.640). CONCLUSION LHx + AR for Bismuth type I/II perihilar cholangiocarcinoma is considered to be a valid alternative to RHx in patients with an insufficient left liver functional reserve.

Diagnosis by 64-Row Multidetector Computed Tomography for Longitudinal Superficial Extension of Distal Cholangiocarcinoma. J Surg Res 2019; 235:487-493. [PMID: 30691833 DOI: 10.1016/j.jss.2018.10.045] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Revised: 08/28/2018] [Accepted: 10/25/2018] [Indexed: 12/13/2022]
Abstract
BACKGROUND This study aimed to demonstrate the diagnostic ability of 64-row multidetector computed tomography (64-row MDCT) for longitudinal superficial extension of distal cholangiocarcinoma (LSEDC). METHODS Twenty-seven patients with distal cholangiocarcinoma (DC) underwent preoperative 64-row MDCT without drainage tubes. LSEDC was diagnosed using curved planar reconstruction images reconstructed from 64-row MDCT, which were compared with pathologic findings. RESULTS LSEDC was observed in 13 patients (48%). Ten patients (37%) had enhancing nonthickened bile ducts extending continuously from the main tumor (type 1). These coincided with pathologic findings of high-grade dysplasia (HGD) in 90.0% of cases; that is, a positive predictive value (9/10). Fourteen patients (52%) had only wall thickening of the main tumor with or without enhancement (type 2). Four patients with HGD in this group were difficult to diagnose. Three patients (11%) had enhancing nonthickened bile ducts not in continuity with the main tumor (type 3). This finding revealed an inflammatory change instead of a carcinoma in the pathologic findings. The sensitivity and specificity of detecting HGD were 75% and 93% on the liver side, 33% and 100% on the duodenal side, respectively. Four patients (67%) with HGD on the liver side were overdiagnosed, and one patient (17%) was underdiagnosed. Most of the patients overdiagnosed on the liver side (3/4 or 75%) had drainage tubes inserted before the MDCT. CONCLUSIONS For DC patients without drainage tubes, the 64-row MDCT technique may be useful for diagnosing HGD depicted as LSEDC on the liver side but not as useful on the duodenal side.

Abstract
BACKGROUND To compare the diagnostic performance of CT criteria and to establish a new model in evaluating portal venous invasion by hilar cholangiocarcinoma. METHODS CT images of 67 patients with hilar cholangiocarcinoma were retrospectively reviewed. Modified Loyer's, Lu's and Li's standard introduced from pancreatic cancer were used to evaluate portal venous invasion with the reference of intraoperative findings and/or postoperative pathological diagnosis. A new model was constructed with modified Lu's standard and contact length between portal vein and tumor. RESULTS The modified Loyer's standard, modified Lu's standard and Li's standard showed a sensitivity of 86.7%, 83.3%, 70.0%, a specificity of 89.4%, 95.7%, 95.7% and an accuracy of 88.6%, 92.0%, 88.1%, respectively. CT criteria performed better in evaluating left branch. The new model performed significantly better than any CT criterion or contact length, with a sensitivity of 95.0%, a specificity of 96.5% and an accuracy of 96.0%. CONCLUSIONS Modified Lu's standard performed best in evaluating portal venous invasion by hilar cholangiocarcinoma among three CT criteria. The left branch invasion could be evaluated by CT criteria better than the right branch and the trunk of portal vein. The new mode significantly improved the diagnostic performance of portal venous invasion by hilar cholangiocarcinoma.

Abstract
BACKGROUND Although multidetector-row computed tomography (MDCT) before biliary drainage is useful for the assessment of the resectability of perihilar cholangiocarcinoma (PHC), the impact of biliary drainage on MDCT images before surgical resection for PHC has been poorly studied, and its possible consequences for R0 resection of PHC remain unclear. This study was performed to compare the surgical outcomes of patients with PHC who underwent MDCT before versus after biliary drainage. METHODS All consecutive patients who underwent major hepatectomy extending to segment 1 with extrahepatic bile duct resection for PHC from 2009 to 2016 were retrospectively evaluated. R0 resection was defined as no residual cancer at all surgical margins. Patients with pathological stage IV PHC were excluded. RESULTS Of 142 patients who underwent major hepatectomy, 108 were eligible for this study. Of these 108 patients, 64 (59%) and 44 (41%) underwent MDCT before and after biliary drainage, respectively. The total bilirubin concentration at presentation was lower in patients who underwent MDCT before than after biliary drainage (4.1 ± 5.9 vs. 8.0 ± 7.1 mg/ml, respectively; p = 0.002). Although there were no significant differences in the surgical characteristics or pathological stages between the two groups, R0 resection was more frequently achieved in patients who underwent MDCT before than after biliary drainage [46/64 (72%) vs. 22/44 (50%), respectively; p = 0.03]. On multivariate analysis, MDCT before biliary drainage was independently associated with R0 resection of PHC (risk ratio: 2.38, 95% CI 1.05-5.41; p = 0.04). CONCLUSIONS In selected patients, MDCT should be performed before biliary drainage to achieve R0 resection of PHC.

Abstract
BACKGROUNDS We aimed to investigate the diagnostic accuracy of multidetector-row computed tomography (MDCT), mapping biopsy, and other imaging modalities to predict the longitudinal extension and depth of invasion of extrahepatic cholangiocarcinoma at possible surgical ductal margins. METHODS Of 102 patients with surgical resection of extrahepatic cholangiocarcinoma between January 2010 and October 2015, 32 evaluated by multidetector-row computed tomography (MDCT) performed before biliary drainage and mapping biopsy were enrolled. Mapping biopsies were performed at 74 sites to determine the resection point of the bile duct (at 74 possible surgical ductal margins). Diagnostic accuracy was evaluated by histopathology. RESULTS The diagnostic accuracy of MDCT for longitudinal cancer spread was 79.7%, that of biopsy was 73.0%, and combining the two modalities showed highest accuracy (83.8%). The depth of tumor invasion could be predicted by combination of the ductal wall thickness and contrast enhancement on MDCT, that is, at 11 of 13 sites (84.6%) with submucosal invasion, ductal wall thickness was > 2.5 mm with high contrast enhancement. CONCLUSIONS MDCT demonstrated highest accuracy of diagnosing longitudinal extension at possible surgical ductal margins in patients with extrahepatic cholangiocarcinoma. The depth of tumor invasion could be predicted by ductal wall thickness and contrast enhancement of MDCT.

Abstract
BACKGROUND AND STUDY AIMS To decrease complications associated with preoperative endoscopic nasobiliary drainage (ENBD) for perihilar cholangiocarcinoma patients, we developed a modified 6-Fr ENBD catheter with multiple side holes (m-ENBD). The aim of this retrospective study was to compare the m-ENBD catheter with a conventional 7-Fr ENBD catheter (c-ENBD). PATIENTS AND METHODS This study involved 371 patients with suspected perihilar cholangiocarcinoma who underwent ENBD using a c-ENBD catheter or an m-ENBD catheter. The effectiveness of each catheter and the incidence of complications were evaluated. Univariate and multivariate analyses followed by propensity score matching were performed. RESULTS In 145 patients with total bilirubin levels ≥ 2.0 mg/dL prior to drainage, these levels decreased to < 2.0 mg/dL after ENBD in 81.1 % of the c-ENBD patients and in 74.0 % of the m-ENBD patients ( P = 0.325). Post-ENBD cholangitis occurred in 24.9 % of the c-ENBD patients and in 12.4 % of the m-ENBD patients ( P = 0.006). After propensity score matching, the rate of post-ENBD cholangitis ( P = 0.007) and the number of patients requiring subsequent or additional drainage ( P = 0.030) were significantly lower in the m-ENBD group. CONCLUSION The modified 6-Fr ENBD catheter was associated with a lower incidence of post-ENBD cholangitis than the conventional 7-Fr ENBD catheter, and the incidence of subsequent or additional drainage procedures was also decreased.

Komaya K, Ebata T, Yokoyama Y, Igami T, Sugawara G, Mizuno T, Yamaguchi J, Nagino M. Recurrence after curative-intent resection of perihilar cholangiocarcinoma: analysis of a large cohort with a close postoperative follow-up approach. Surgery 2018; 163:732-738. [PMID: 29336813 DOI: 10.1016/j.surg.2017.08.011] [Citation(s) in RCA: 81] [Impact Index Per Article: 13.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2017] [Revised: 08/18/2017] [Accepted: 08/30/2017] [Indexed: 01/04/2023]
Abstract
BACKGROUND Although several studies have been conducted on the patterns of recurrence in resected perihilar cholangiocarcinoma, they have many limitations. The aim of this study was to investigate recurrence after resection and to evaluate prognostic factors on the time to recurrence and recurrence-free survival. METHODS Consecutive patients who underwent curative-intent resection of perihilar cholangiocarcinoma between 2001 and 2012 were reviewed retrospectively. The Cox proportional hazards model was used for multivariable analysis. RESULTS In the study period, 402 patients underwent resection of perihilar cholangiocarcinoma (R0, n = 340; R1, n = 62). Radial margin positivity (n = 43, 69%) was the most common reason for R1 resection. The median follow-up of survivors was 7.4 years. The cumulative recurrence probability was higher in R1 than in R0 resection (86% vs 57% at 5 years, P < .001). Seventeen R0 patients had a recurrence over 5 years after resection. There was no difference in median survival time after recurrence between R0 and R1 resection (10 vs 7 months). The proportion of isolated locoregional recurrence was higher in R1 than in R0 resection (37% vs 16%, P < .001), whereas the proportion of distant recurrence was similar. In R0 resection, the independent prognostic factors for time to recurrence and recurrence-free survival were microscopic venous invasion and lymph node metastasis. CONCLUSION More than half of patients with perihilar cholangiocarcinoma experience recurrence after R0 resection. These recurrences occur frequently within 5 years but occasionally after 5 years, which emphasizes the need for close and long-term surveillance. Adjuvant strategies should be considered, especially for patients with nodal metastasis or venous invasion even after R0 resection.

Abstract
Cholangiocarcinomas (CC) are rare tumors which usually present late and are often difficult to diagnose and treat. CCs are categorized as intrahepatic, hilar, or extrahepatic. Epidemiologic studies suggest that the incidence of intrahepatic CCs may be increasing worldwide. In this chapter, we review the risk factors, clinical presentation, and management of cholangiocarcinoma.

Abstract
BACKGROUND 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 type IV perihilar cholangiocarcinoma. METHODS Medical records of consecutive patients with a diagnosis of type IV perihilar cholangiocarcinoma between 2006 and 2015 were reviewed retrospectively. Primary outcomes assessed were surgical results and long-term survival. RESULTS Of the 332 patients with type IV tumour, 216 (65·1 per cent) underwent resection. Left hepatic trisectionectomy was the most common procedure (112 patients). Combined vascular resection was performed in 131 patients. Median duration of operation was 607 (range 356-1045) min, and blood loss was 1357 (209-10 349) ml. Complications of Clavien-Dindo grade III or more developed in 90 patients (41·7 per cent) and four (1·9 per cent) died from complications within 90 days. Survival rates were better for the 216 patients whose tumours were resected than for the 116 patients with unresected tumours (32·8 versus 1·5 per cent at 5 years; P < 0·001). Patients with pN0 M0 disease after resection had a favourable 5-year survival rate of 53 per cent. Percutaneous transhepatic biliary drainage, blood transfusion, lymph node metastasis and distant metastasis were identified as independent negative prognostic factors for survival. CONCLUSION Although resection for type IV tumour is technically demanding with high morbidity, it can be performed with low mortality and offers better survival probability in selected patients.

Abstract
Purpose This study was conducted to evaluate the impact of radiation dose after margin involved resection in patients with extrahepatic bile duct cancer. Methods Among the 251 patients who underwent curative resection followed by adjuvant chemoradiotherapy, 86 patients had either invasive carcinoma (n = 63) or carcinoma in situ (n = 23) at the resected margin. Among them, 54 patients received conventional radiation dose (40-50.4 Gy) and 32 patients received escalated radiation dose (54-56 Gy). Results Escalated radiation dose was associated with improved locoregional control (5yr rate, 73.8% vs. 47.1%, p = 0.069), but not disease-free survival (5yr rate, 43.4% vs. 32.6%, p = 0.490) and overall survival (5yr rate, 40.6% vs. 29.6%, p = 0.348). In multivariate analysis for locoregional control, invasive carcinoma at the margin (HR 2.957, p = 0.032) and escalated radiation dose (HR 0.394, p = 0.047) were independent prognostic factors. No additional gastrointestinal toxicity was observed in escalated dose group. Conclusions Delivery of radiation dose ≥ 54 Gy was well tolerated and associated with improved locoregional control, but not with overall survival after margin involved resection. Further validation study is warranted.

The development of an automatically produced cholangiography procedure using the reconstruction of portal-phase multidetector-row computed tomography images: preliminary experience. Surg Today 2016; 47:365-374.

Abstract
PURPOSE Fusion angiography using reconstructed multidetector-row computed tomography (MDCT) images, and cholangiography using reconstructed images from MDCT with a cholangiographic agent include an anatomical gap due to the different periods of MDCT scanning. To conquer such gaps, we attempted to develop a cholangiography procedure that automatically reconstructs a cholangiogram from portal-phase MDCT images. METHODS The automatically produced cholangiography procedure utilized an original software program that was developed by the Graduate School of Information Science, Nagoya University. This program structured 5 candidate biliary tracts, and automatically selected one as the candidate for cholangiography. The clinical value of the automatically produced cholangiography procedure was estimated based on a comparison with manually produced cholangiography. RESULTS Automatically produced cholangiograms were reconstructed for 20 patients who underwent MDCT scanning before biliary drainage for distal biliary obstruction. The procedure showed the ability to extract the 5 main biliary branches and the 21 subsegmental biliary branches in 55 and 25 % of the cases, respectively. The extent of aberrant connections and aberrant extractions outside the biliary tract was acceptable. Among all of the cholangiograms, 5 were clinically applied with no correction, 8 were applied with modest improvements, and 3 produced a correct cholangiography before automatic selection. CONCLUSIONS Although our procedure requires further improvement based on the analysis of additional patient data, it may represent an alternative to direct cholangiography in the future.

Abstract
BACKGROUND Major hepatectomy with concomitant pancreatoduodenectomy (major-HPD) is the only procedure that provides a curative resection for diffusely spread extrahepatic bile duct cancer (DSEBDC). We sometimes encounter patients who cannot undergo major-HPD because of a poor functional hepatic reserve. The aim of the present study was to assess the feasibility of central hepatectomy with pancreatoduodenectomy (central-HPD) for patients with DSEBDC as an alternative to major-HPD. METHODS Between 2002 and 2010, six patients with DSEBDC underwent central-HPD. The hepatectomy procedures for central-HPD included central bisectionectomy with S1 resection (S1r) and right anterior sectionectomy with S1r. RESULTS The estimated resection liver volume was decreased from 77.5% to 46.6% by the application of central-HPD. The median operative duration was 929 min, and the median blood loss was 2568 ml. Postoperative complications were observed in five patients. The proximal ductal stump was histologically positive with non-invasive cancer in three patients and positive with invasive cancer in one. The overall survival of the six patients was 62.5% at 5 years after surgery. CONCLUSIONS While central-HPD was a technically complicated procedure associated with a high morbidity rate, it offered a favorable overall survival and might be an alternative option for DSEBDC patients with a poor hepatic functional reserve.

Abstract
BACKGROUND Biliary strictures following laparoscopic cholecystectomy (Lap-C), which are often associated with vascular injuries, remain a serious problem to manage. The aim of this study was to review our experiences with postoperative biliary stricture. METHODS This study involved 14 consecutive patients with biliary strictures that resulted from bile duct injuries during Lap-C between 1997 and 2013. Their medical records were retrospectively analyzed. RESULTS Percutaneous transhepatic biliary drainage (PTBD) catheter dilatation was first attempted in eight patients, and five patients were successfully treated. Biliary re-stricture recurred in one patient after 34-month follow-up period. This patient underwent repeated catheter dilatations, which led to recurrent stricture resolution. All five patients maintained biliary tract patency over 72-month follow-up period. The remaining nine patients underwent surgical procedures, including hepaticojejunostomy in two patients, re-hepaticojejunostomy in two patients, and the remaining five patients, with biliary strictures involving the secondary biliary branch and concomitant vascular injuries underwent right hemihepatectomy with cholangiojejunostomy. There were no major postoperative complications. After 80-month follow-up period, all nine patients were alive without biliary stricture. CONCLUSIONS PTBD catheter dilatation is recommended first for postoperative Lap-C-associated biliary strictures. In complicated injury patients with vascular injuries, right hemihepatectomy with cholangiojejunostomy should be indicated.

Abstract
OBJECTIVE To evaluate recent surgical strategy for hilar cholangiocarcinoma (HC) of the left-side predominance. BACKGROUND When employing left hemihepatectomy (LH) for HC, vasculobiliary anatomy of the right liver often makes it difficult to achieve a tumor-free margin of the right posterior sectional bile duct (RPSBD). Because left trisectionectomy (LTS) can produce a longer resection margin for the RPSBD, we have expanded the indications for LTS over the last 5 years. METHODS Sixty-one consecutive patients underwent left-sided hepatectomy for HC, divided into 2 groups according to the operative periods: period 1 (2001-2007; n = 29) and period 2 (2008-2012; n = 32). Clinicopathological outcomes of the groups were compared. The difference in the length of the resectable RPSBD between LH and LTS was radiologically investigated using multidetector-row computed tomography. RESULTS The proportion of LTS increased from 10.3% (3/29) in period 1 to 46.9% (15/32) in period 2. R0 resection rates were also improved in period 2. The most common margin positive site in period 1 was the stump of the proximal bile duct; high rates of positive RPSBD stump were noted after LH. The positive proximal ductal margin ratio decreased significantly in period 2. The difference in the length of resectable RPSBD between LH and LTS was 9.0 ± 1.3 mm. There was no mortality in period 2, even after LTS. CONCLUSIONS LTS for HC of the left-side predominance improved R0 resection rates without affecting postoperative mortality. LTS should be aggressively performed in patients with appropriate hepatic function, even if tumors are possibly resectable by LH.

Abstract
Perihilar cholangiocarcinomas often involve the bifurcation of the portal vein and the hepatic artery at initial presentation. Previously, vascular invasion was a major obstacle for R0 resection; therefore, such tumors were regarded as locally advanced, unresectable disease. Recently, in leading centers, these tumors have been resected using a specific technique, vascular resection and reconstruction. Vascular resection is classified into three types: portal vein resection alone, hepatic artery resection alone, and simultaneous resection of both the portal vein and hepatic artery. Of these, portal vein resection is widely performed, whereas hepatic artery resection remains controversial. Therefore, hepatectomy combined with simultaneous resection of the portal vein and hepatic artery represents one of the most complicated and challenging procedures in hepatobiliary surgery. The survival benefit of this extended procedure remains unproven, and there is only a single study reporting an unexpectedly favorable outcome in 50 patients. Considering the dismal survival in patients with unresectable disease, hepatic artery resection and/or portal vein resection may be a promising option of choice. However, the technique is highly demanding and has not been standardized. Therefore, this extended surgery may be allowed only in selected hepatobiliary centers.

Abstract
Assessment of surgical resectability in cholangiocarcinoma is more complicated than other gastrointestinal malignancies and remains unestablished. According to the primary origin and tumor extent, the applied surgical procedure varies from extrahepatic bile duct resection to right or left trisectionectomy concomitant with pancreatoduodenectomy. Portal vein resection and reconstruction during hepatectomy has been feasible. Thanks to the availability of new microscopic surgical techniques, hepatic arterial resection and reconstruction have also come to be applied for locally advanced cholangiocarcinoma cases. These vascular surgical techniques can expand surgical indications for advanced cholangiocarcinoma. On the other hand, determination of the tumor extent or staging still remains difficult and imprecise. The endoscopic approach has come to play significant roles both for preoperative biliary drainage and tumor staging. Estimation of the functional reserve of future remnant liver in cholestatic patients still remains unresolved. Hepatobiliary surgeons should carefully estimate the safety of the surgical procedure in each individual patient requiring extensive hepatobiliary resection. Early establishment of the measurement methods of the functional capacity of future remnant liver is an important and urgent issue for assessing safer surgical resectablity of cholangiocarcinoma.

Abstract
OBJECTIVE 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. BACKGROUND Few studies have reported improved surgical outcomes for perihilar cholangiocarcinoma; therefore, it is still unclear whether surgical treatment of this intractable disease has progressed. METHODS Between April 1977 and December 2010, a total of 754 consecutive patients with perihilar cholangiocarcinoma were treated, of whom 574 (76.1%) underwent resection. The medical records of these resected patients were retrospectively reviewed. RESULTS The incidence of major hepatectomies has increased, and limited resections, including central hepatectomies and bile duct resections, were rarely performed. Combined vascular resection was being used more often. Operative time has become shorter, and intraoperative blood loss has also decreased significantly. Because of refinements in surgical techniques and perioperative management, morbidity decreased significantly but was still high, with a rate of 43.1% in the last 5 years. Mortality rate has also decreased significantly (P < 0.001) from 11.1% (8/72) before 1990 to 1.4% (3/218) in the last 5 years. The ratio of advanced disease defined as pStage IVA and IVB has increased significantly from 49.4% before 2000 to 61.4% after 2001. The disease-specific survival for the 574 study patients (including all deaths) was 44.3% at year 3, 32.5% at year 5, and 19.9% at year 10. The survival was significantly better in the later period of 2001 to 2010 than in the earlier period of 1977 to 2000 (38.1% vs 23.1% at year 5, P < 0.001). For pM0, R0, and pN0 patients (n = 243), the survival in the later period was good with 67.1% at year 5, which was significantly better than that of the earlier period (P < 0.001). For pM0, R0, and pN1 patients (n = 142), however, the survival in the later period was similar to that of the earlier period (22.1% vs 14.6% at year 5, P = 0.647). Multivariate analysis revealed that lymph node metastasis was the strongest prognostic indicator. CONCLUSIONS Surgical treatment of perihilar cholangiocarcinoma has been evolving steadily, with expanded surgical indication, decreased mortality, and increased survival. Survival for R0 and pN0 patients was satisfactory, whereas survival for pN1 patients was still poor, suggesting that establishment of effective adjuvant chemotherapy is needed.

Abstract
The aim of this study was to evaluate 64-slice spiral CT image reconstruction of the portal vein in biliary obstruction. A total of 34 clinical patients with biliary obstruction were confirmed by 64-slice spiral CT scanning with portal venous phase multi-planar reconstruction (MPR) of the biliary tract, curved planar reconstruction (CPR), thin-slab minimum-intensity projection (TS-MinIP) and maximum intensity projection (MIP). The reconstructed images were reviewed to further assess the position and cause of the biliary obstruction and to judge the accuracy of diagnosis. The 64-slice spiral CT image reconstruction of the biliary obstructions determined the causes with an accuracy of 88.2% (30/34) and identified the location of the obstruction with an accuracy of 100%. A 64-slice spiral CT reconstructed image of the portal bile duct lesions was generated, which indicated the lesion morphology, location and anatomical relationship with surrounding tissues, secondary biliary stricture and the degree of expansion and is of great clinical value in the characterization and preoperative evaluation of biliary disease.

Preoperative endoscopic nasobiliary drainage in 164 consecutive patients with suspected perihilar cholangiocarcinoma: a retrospective study of efficacy and risk factors related to complications. Ann Surg 2013; 257:121-7.

Abstract
OBJECTIVE To assess the clinical benefits of preoperative endoscopic nasobiliary drainage (ENBD) in patients with perihilar cholangiocarcinoma. BACKGROUND The advantages of ENBD have been previously reported. However, no studies to date have examined a large number of patients, including those with Bismuth-Corlette (B-C) type III to IV tumors. In addition, sufficient data on the risk factors associated with ENBD complications are not available. METHODS This study involved 164 consecutive patients with suspected perihilar cholangiocarcinoma (128 patients with B-C type III-IV tumors) who had undergone unilateral ENBD between January 2007 and December 2010. The success and efficacy of this procedure and the risk factors for post-ENBD cholangitis and pancreatitis were retrospectively evaluated. RESULTS The ENBD procedure was successful in 153 (93.3%) of the 164 patients. Of these 164 patients, 65 had serum total bilirubin (TB) levels of 2.0 mg/dL or more before the drainage. The first unilateral ENBD was successfully performed in 60 of the 65 patients, and the TB level decreased to less than 2.0 mg/dL after ENBD in 50 of these 60 patients (83.3%). The significant predictive factors for ENBD efficacy included the pre-ENBD TB level (P = 0.032; 95% confidence interval [CI], 1.01-1.23) and post-ENBD cholangitis (P = 0.012; 95% CI, 1.61-43.2). Post-ENBD cholangitis occurred in 47 (28.8%) of the 163 patients, and a previous endoscopic sphincterotomy (EST) was found to be a significant risk factor for post-ENBD cholangitis (P = 0.008; 95% CI, 1.30-5.46). Post-ENBD pancreatitis occurred in 33 (20.1%) of the 164 patients (26 grade 1 patients, 4 grade 2 patients, and 3 grade 3 patients). The significant risk factors included undergoing pancreatography (P < 0.001; 95% CI, 2.44-31.1) and the absence of previous EBS or ENBD (P < 0.001; 95% CI, 3.03-29.2). CONCLUSIONS Unilateral ENBD of the future remnant lobe(s) exhibited a high success rate, suggesting that it is an effective and suitable preoperative drainage method for perihilar cholangiocarcinoma even in patients with B-C type III to IV tumors. To reduce the postprocedural complications, ENBD should be performed without EST or pancreatography.

Abstract
Clinical guidelines of the European Society of Gastrointestinal Endoscopy recommend the insertion of self-expandable metallic stents (SEMS) as opposed to plastic stents (PS) in patients with unresectable malignant perihilar stricture (MHS). However, PS are cheaper and easier to insert into the biliary duct compared to SEMS. Furthermore, PS are removable and easy to move into subsequent drainage procedures. We conducted the present retrospective single-center study to elucidate the predictive factors associated with stent patency period duration in patients with unresectable MHS who would benefit from a long patency period after PS placement. This study included 56 consecutive patients with unresectable MHS who were drained using PS. PS failure occurred in 26 (46.4%) patients. The median patency period was 72 days (95% confidence interval: 29.8-114). The only significant predictive factor associated with the length of the stent patency period was history of previous endoscopic sphincterotomy (EST). Median patency periods with and without previous EST were 28 and 109 days, respectively (P = 0.016). In conclusion, we suggest that conventional biliary drainage with PS is still a suitable option for the treatment of unresectable MHS in patients without previous EST.

Abstract
BACKGROUND A salvage hepatectomy for an "inoperable" advanced perihilar tumor initially treated with a self-expanding metallic stent (SEMS) is challenging, and its safety and survival benefits remain unclear. The aim of this study was to report our experiences with this difficult resection. METHODS This study involved 10 consecutive patients with suspected perihilar cholangiocarcinoma who underwent SEMS placement at a local hospital and were referred to our clinic for possible resection as their last option. Their medical records were analyzed retrospectively. RESULTS Tumor extent was first reevaluated using multidetector-row computed tomography. Of the 10 patients, 4 were diagnosed as inoperable owing to locally advanced tumors (n = 3) or poor physical condition (n = 1). In the remaining 6 patients, after additional biliary drainage, a salvage hepatectomy was performed, including a right hepatectomy with a caudate lobectomy in 5 patients and a central bisectionectomy with a caudate lobectomy in 1. A combined portal vein resection was required in 3 patients, and a combined pancreatoduodenectomy was performed in 2 patients. R0 resection was achieved in 5 patients, and all patients tolerated the resection. Three patients died of recurrence, and the remaining 3 were alive without recurrence at the time of publication, 1 of whom has survived >10 years. CONCLUSION Pre-resection SEMS placement does not preclude a subsequent hepatectomy for patients with advanced perihilar tumors. Salvage hepatectomy, although technically demanding, is feasible and can revise the palliative scenario and benefit selected patients treated initially with an SEMS.

Abstract
Perihilar cholangiocarcinomas are defined anatomically as "tumors that are located in the extrahepatic biliary tree proximal to the origin of the cystic duct". However, as the boundary between the extrahepatic and intrahepatic bile ducts is not well defined, perihilar cholangiocarcinomas potentially include two types of tumors: one is the "extrahepatic" type, which arises from the large hilar bile duct, and the other is the "intrahepatic" type, which has an intrahepatic component with the invasion of the hepatic hilus. The new TNM staging system published by the International Union Against Cancer (UICC) has been well revised with regard to perihilar cholangiocarcinoma, but it still lacks stratification of patient prognosis and has little applicability for assessing the feasibility of surgical treatment; therefore, further refinement is essential. Most patients with perihilar cholangiocarcinomas present with jaundice, and preoperative biliary drainage is mandatory. Previously, percutaneous transhepatic biliary drainage was used in many centers; however, it is accepted that endoscopic naso-biliary drainage is the most suitable method of preoperative drainage. Portal vein embolization is now widely used as a presurgical treatment for patients undergoing an extended hepatectomy to minimize postoperative liver dysfunction. The surgical resection of a perihilar cholangiocarcinoma is technically demanding and continues to be the most difficult challenge for hepatobiliary surgeons. Because of advances in diagnostic and surgical techniques, surgical outcomes and survival rates after resection have steadily improved. However, survival, especially for patients with lymph node metastasis, is still unsatisfactory, and the establishment of adjuvant chemotherapy is necessary. Further synergy of endoscopists, radiologists, oncologists, and surgeons is required to conquer this intractable disease.

Abstract
PURPOSE Although left-sided hepatectomy, such as a left hepatectomy or left trisectionectomy with resection of the caudate lobe and extrahepatic bile duct, is used to treat hilar cholangiocarcinoma predominantly involving the left side of the hepatic hilum, it is associated with several difficult technical points. The important points during left-sided hepatectomy are described here. TECHNIQUES There are anatomical variations of the sectional artery and bile duct. It is essential to understand the individual intrahepatic and hilar anatomy preoperatively. Surgical procedures consist of lymph node clearance, dissection of the distal bile duct, skeletonization resection of the hepatoduodenal ligament, mobilization of the liver and liver resection, dissection of the intrahepatic bile ducts, and biliary reconstruction. During lymph node dissection and skeletonization resection of the hepatoduodenal ligament, the nerve plexus around the hepatic artery is dissected, and its adventitia is exposed with great care to avoid injuring the hepatic artery. Mobilization of the caudate lobe is performed only from the left side. There is no clear landmark between the caudate lobe and the right posterior section during liver resection. In the final step of liver resection, it progresses toward the right edge of the inferior vena cava. When dividing intrahepatic bile ducts, extreme care should be used to avoid injury to the corresponding hepatic arteries, especially the anomalous supraportal posterior sectional artery. CONCLUSIONS Left-sided hepatectomy for hilar cholangiocarcinoma should be considered a more complicated and technically demanding procedure than right-sided hepatectomy. Surgeons need to pay close attention to anatomical variations in order to perform a left-sided hepatectomy safely and successfully.

Abstract
BACKGROUND Complete resection of hilar cholangiocarcinoma (HCCA) is a critical determinant of long-term survival. This study validates a previously reported preoperative clinical T staging system for determining resectability of HCCA. STUDY DESIGN Consecutive patients with confirmed HCCA treated over an 18-year period were included. Patient demographics, preoperative imaging studies, resection type, margin status, lymph node status, histopathologic findings, morbidity, and outcomes were entered prospectively and analyzed retrospectively; changes in these variables over time were assessed. All patients were placed into 1 of 3 stages based on the extent of ductal involvement by tumor, portal vein compromise, or lobar atrophy. RESULTS From March 1991 through December 2008, 380 patients were evaluated. Eighty-five patients had unresectable disease; 295 patients underwent exploration with curative intent. One hundred fifty-seven patients underwent resection: 129 (82.2%) had a concomitant hepatic resection and 120 (76.4%) had an R0 resection. Of the 32 actual 5-year survivors (120 at risk), 30 patients (93.8%) had a concomitant hepatic resection. In patients who underwent an R0 resection, concomitant partial hepatectomy, well-differentiated histology, and negative lymph nodes were independent predictors of long-term survival. In the 376 patients whose disease could be staged, the preoperative clinical T staging system predicted resectability (p < 0.001), metastatic disease (p < 0.001), and R0 resection (p = 0.007). CONCLUSIONS The preoperative clinical T staging system of Blumgart, defined by the radial and longitudinal tumor extent, accurately predicts resectability of HCCA. The full outcomes benefit of resection is realized only if a concomitant partial hepatectomy is performed.

Abstract
OBJECTIVE To evaluate the preoperative factors predictive of postoperative early recurrence in patients with resected pancreatic cancer focusing on the serum CA19-9 value. METHODS One hundred fifty-four patients undergoing surgical resection for pancreatic cancer were enrolled in this study. Univariate and multivariate analyses were performed to determine the predictors of early recurrence which was defined as relapse within 6 months after surgery. RESULTS On ROC curve analysis, the cutoff value of CA19-9 was determined to be 100 U/ml. Of 73 patients with CA19-9 value ≥ 100 U/ml, 39 (53 %) had early recurrence. In contrast, only 9 of 81 patients (11 %) with CA19-9 value < 100 U/ml developed a recurrence at an early period (p < 0.001). Multivariate analysis revealed that CA19-9 value ≥ 100 U/ml (odds ratio, 11.2) were significant predictors of early recurrence. The overall 3- and 5-year survival rates and median survival times were 47.3 %, 40.1 %, and 31 months in patients with CA19-9 value < 100 U/ml and 21.2 %, 9.4 %, and 16 months in patients with CA19-9 value ≥ 100 U/ml (p < 0.001). CONCLUSIONS A preoperative CA19-9 value ≥ 100 U/ml was a significant predictor of early recurrence and a poor prognosis after resection for pancreatic adenocarcinoma.

Abstract
BACKGROUND The sensitivity of transpapillary biliary forceps biopsy for malignancy has been reported as varying from 43-81%. Therefore, there are false negatives in more than 20% of patients, which makes it difficult to diagnose benign biliary stricture as benignancy in a clinical setting. METHODS To clarify the number of tissue samples that should be obtained during transpapillary forceps biopsy to distinguish benign biliary stricture from malignancy, patients undergoing transpapillary biliary forceps biopsy at our institute were examined retrospectively in this study. RESULTS Seventy-two biliary forceps biopsy procedures were performed on 61 patients. The final diagnoses were malignant biliary stricture in 34 patients and benign stricture in 27 patients. The overall sensitivity and specificity for malignancy in this study were 76.5% and 100%, respectively. There were zero out of 10 (0%) false-negative patients when three or more tissue samples were obtained. In contrast, when four or more tissue samples were obtained, eight out of eight (100%) patients had negative diagnoses for malignancy and were finally diagnosed with benignancy. CONCLUSION We suggest that three or more tissue samples are recommended for the diagnosis of biliary malignant stricture.

Abstract
OBJECTIVE To assess the survival benefit of additional resection of an intraoperative positive proximal bile duct margin (BD(Marg)) in patients undergoing hepatectomy for hilar cholangiocarcinoma (HCCA). SUMMARY BACKGROUND DATA Intraoperative evidence of invasive cancer at the proximal (BD(Marg)) is associated with a dismal survival irrespective of whether a final negative (BD(Marg)) is achieved with an additional resection. METHODS Clinicopathologic, operative, and survival data of consecutive patients undergone curative intent hepatectomy with bile duct resection (n = 75) for HCC (1989-2010) were analyzed. RESULTS Frozen-section examination of the proximal (BD(Marg)) revealed invasive cancer in 19 of the 67 patients. After additional resection, which was possible in 18 cases, a secondary R0 (BD(Marg)) resection was achieved in 15 patients (83.3%), with 2 of these having, at final pathology, positive radial and distal margins. Eventually, 8 patients were classified as R1 and 67 as R0 (54 primary R0 and 13 secondary R0). Median survival of patients who had a secondary R0 resection (30.6 months) was similar to that of primarily R0-resected patients (29.3 months) and significantly better than that of R1 patients (14.9 months) (P = 0.026). Median time to recurrence and site of recurrence were similar in R0 patients independently of the performance of an additional resection. The incidence of biliary fistula was significantly increased (44.4% vs 17.5%; P = 0.02) in patients necessitating a margin re-resection. CONCLUSIONS Additional resection of a positive proximal (BD(Marg)) , albeit associated with an increased risk of biliary fistula, offers a significant survival benefit and should be attempted whenever possible.

Abstract
We report a rare case of hepatolithiasis, which was diagnosed as hilar cholangiocarcinoma and treated with hepatectomy and extrahepatic bile duct resection. A 59-year-old woman presented to a local hospital with liver dysfunction. Diagnostic imaging revealed a biliary stricture at the hepatic hilum and middle bile duct. Hilar cholangiocarcinoma was diagnosed, and she was referred to our hospital for definitive surgical treatment. She underwent left hepatic trisectionectomy, total caudate lobectomy, and extrahepatic bile duct resection. Gross examination of the resected specimen revealed intrahepatic stones firmly adherent to the bile duct wall. Pathological examination revealed no malignant lesions. The epithelium of the bile duct was absent underneath the stone, and the boundary between the stone and bile duct wall was ill defined. To our knowledge, this is the first case report of hepatolithiasis with a biliary stricture caused by peculiar stone formation, mimicking hilar cholangiocarcinoma.

Abstract
OBJECTIVE To clarify the value of resection of gallbladder cancer involving the extrahepatic bile duct. BACKGROUND : Several recent studies have proven that jaundice and extrahepatic biliary involvement are independent predictors of a poor outcome. Only a few authors recommend resection of such advanced disease. METHODS One hundred patients with pT3/4, pN0/1, M0 disease were the subjects of this study. Mortality and long-term outcome were analyzed using a prospectively collected database. RESULTS The only factor associated with mortality in univariate and multivariate analyses was intraoperative blood loss. The 5-year survival rate and median survival time were 23% and 1.5 years for patients with pathologic extrahepatic biliary invasion (pEBI), and 54% and 15.4 years for patients without pEBI. Twelve patients with pEBI survived beyond 5 years. Multivariate analysis revealed that R1/2 resection and combined resection of adjacent organs other than the liver and extrahepatic bile duct (CRAO) were independent predictors of poor outcome. Five-year survival rate and median survival time after R0 resection without CRAO were 36% and 3.8 years even in patients with pEBI. In contrast, after R0 resection with CRAO 5-year survival and median survival time were 16% and 0.8 years, respectively. CONCLUSIONS Patients with advanced gallbladder cancer with pEBI are candidates for resection when distant metastases are absent and R0 resection is achievable. When CRAO is unnecessary, surgical resection should be aggressively planned.

Abstract
The accurate diagnosis of extrahepatic bile duct carcinoma is difficult, even now. When ultrasonography (US) shows dilatation of the bile duct, magnetic resonance cholangiopancreatography followed by endoscopic US (EUS) is the next step. When US or EUS shows localized bile duct wall thickening, endoscopic retrograde cholangiopancreatography should be conducted with intraductal US (IDUS) and forceps biopsy. Fluorescence in situ hybridization increases the sensitivity of brush cytology with similar specificity. In patients with papillary type bile duct carcinoma, three biopsies are sufficient. In patients with nodular or infiltrating-type bile duct carcinoma, multiple biopsies are warranted, and IDUS can compensate for the limitations of biopsies. In preoperative staging, the combination of dynamic multi-detector low computed tomography (MDCT) and IDUS is useful for evaluating vascular invasion and cancer depth infiltration. However, assessment of lymph nodes metastases is difficult. In resectable cases, assessment of longitudinal cancer spread is important. The combination of IDUS and MDCT is useful for revealing submucosal cancer extension, which is common in hilar cholangiocarcinoma. To estimate the mucosal extension, which is common in extrahepatic bile duct carcinoma, the combination of IDUS and cholangioscopy is required. The utility of current peroral cholangioscopy is limited by the maneuverability of the “baby scope”. A new baby scope (10 Fr), called “SpyGlass” has potential, if the image quality can be improved. Since extrahepatic bile duct carcinoma is common in the Far East, many researchers in Japan and Korea contributed these studies, especially, in the evaluation of longitudinal cancer extension.

Abstract
The aim of this review is to describe recent advances and topics in the surgical management of bile duct cancer. Radical resection with a microscopically negative margin (R0) is the only way to cure cholangiocarcinoma and is associated with marked survival advantages compared to margin-positive resections. Complete resection of the tumor is the surgeon’s ultimate aim, and several advances in the surgical treatment for bile duct cancer have been made within the last two decades. Multidetector row computed tomography has emerged as an indispensable diagnostic modality for the precise preoperative evaluation of bile duct cancer, in terms of both longitudinal and vertical tumor invasion. Many meticulous operative procedures have been established, especially extended hepatectomy for hilar cholangiocarcinoma, to achieve a negative resection margin, which is the only prognostic factor under the control of the surgeon. A complete caudate lobectomy and resection of the inferior part of Couinaud’s segment IV coupled with right or left hemihepatectomy has become the standard surgical procedure for hilar cholangiocarcinoma, and pylorus-preserving pancreaticoduodenectomy is the first choice for distal bile duct cancer. Limited resection for middle bile duct cancer is indicated for only strictly selected cases. Preoperative treatments including biliary drainage and portal vein embolization are also indicated for only selected patients, especially jaundiced patients anticipating major hepatectomy. Liver transplantation seems ideal for complete resection of bile duct cancer, but the high recurrence rate and decreased patient survival after liver transplant preclude it from being considered standard treatment. Adjuvant chemotherapy and radiotherapy have a potentially crucial role in prolonging survival and controlling local recurrence, but no definite regimen has been established to date. Further evidence is needed to fully define the role of liver transplantation and adjuvant chemo-radiotherapy.

Abstract
OBJECTIVE To review our surgical experience with hilar cholangiocarcinoma in the "new era." METHODS The medical records of 428 patients with hilar cholangiocarcinoma who underwent treatment between 2001 and 2008 at the First Department of Surgery, the Nagoya University Hospital, were retrospectively reviewed. RESULTS Of the 428 patients, 298 (70%) underwent surgical resection (R0, n = 220; R1, n = 70; R2, n = 8). Portal vein resection was performed in 111 (37%) patients, and hepatic artery resection was performed in 53 (18%) patients. Several different types of postoperative complications occurred in a total of 129 (43%) patients and led to 6 (2%) deaths. Of the 298 resected tumors, 206 (69%) were extrahepatic type tumors, and the remaining 92 (31%) were intrahepatic type tumors. Using the Bismuth classification criteria, we identified 15 (5%) type I, 21 (7%) type II, 120 (40%) type III, and 142 (48%) type IV tumors. The overall 1-, 3-, and 5-year survival rates for all 298 patients were 77, 49, and 42%, respectively. The survival rates were highest among the 197 patients with pM0 disease who underwent R0 resection. Patients in this subgroup had a 5-year survival rate of 52%. The 5-year overall survival rate for the 55 patients with pM0 disease who underwent R1 resection was 32%. The survival rate for patients who had pM1 disease and/or underwent R2 resection was the worst of all the subgroups, but was nonetheless significantly better than that of patients with unresectable tumors. The survival rate for patients who underwent vascular resection and reconstruction was unexpectedly better, with 5-year survival of >20%. CONCLUSIONS The surgical approach to hilar cholangiocarcinoma has become more challenging in the new era. Nevertheless, surgical outcomes have been improved, with decreased morbidity and mortality rates being observed. Long-term survival has also steadily improved. These findings indicate that biliary surgeons should use an aggressive surgical strategy to treat this intractable disease.
