Abstract
BACKGROUND Preoperative recognition of the anatomy of caudate biliary branches is important for the safe and complete resection of perihilar cholangiocarcinoma (PHC). In the present study, we identified these branches using an endoscopic nasobiliary drainage tube (ENBD). METHODS Between January 2012 and October 2022, 89 patients with suspected PHC underwent computed tomographic (CT) cholangiography through ENBD and caudate biliary branching patterns were examined. Multidetector raw CT (MDCT) scans on 85 patients with PHC without biliary drainage were also investigated. The caudate biliary branches detected by each modality were evaluated. RESULTS ENBD-CT cholangiography detected 206 caudate branches (2.44 branches/patient), while MDCT identified 62 branches (0.78 branches/patient). ENBD-CT cholangiography showed that 89 caudate branches drained into the left hepatic duct (LHD), 87 into the posterior hepatic duct (Bpost), and 30 into the right hepatic duct. LHD and Bpost were the common roots of the caudate branches. Some branches (20%) joined the contralateral hepatic duct across the left-right border, but not the anterior hepatic duct or infraportal-type Bpost. CONCLUSIONS ENBD-CT cholangiography clearly showed the caudate biliary branches in patients with PHC after biliary drainage.

Application of three-dimensional visualization technology in early surgical repair of bile duct injury during laparoscopic cholecystectomy. BMC Surg 2024; 24:271. [PMID: 39334148 PMCID: PMC11438028 DOI: 10.1186/s12893-024-02571-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2024] [Accepted: 09/16/2024] [Indexed: 09/30/2024] Open
Abstract
OBJECTIVE This study aimed to explore the application value of three-dimensional (3D) visualization technology in the early surgical repair of bile duct injury during laparoscopic cholecystectomy (LC). METHODS A retrospective analysis was conducted on the clinical data of 15 patients who underwent early surgical repair of bile duct injury during LC with the assistance of 3D visualization technology at the Hepatobiliary Surgery Department of Ningxia Hui Autonomous Region People's Hospital from January 2019 to December 2022. Postoperative efficacy and long-term follow-up outcomes were summarized. RESULTS Before the repair surgery, 15 cases of bile duct injury during LC were evaluated using 3D visualization technology according to the Strasberg-Bismuth classification: 2 cases of type C, 4 of type E1, 3 of type E2, 3 of type E3, and 3 of type E4. Intraoperative findings were consistent with the 3D visualization reconstruction results, and all patients successfully underwent hepaticojejunostomy using Roux-en-Y anastomosis guided by the 3D visualization navigation. The time interval between LC and bile duct repair surgery ranged from 5 to 28 (14.2 ± 9.7) days. The surgical time was between 120 and 190 (156.40 ± 23.92) min, and estimated blood loss ranged from 80 to 250 (119.66 ± 47.60) mL. The length of hospital stay ranged from 12 to 25 days (median: 16 days). One patient experienced mild bile leakage after the operation, which healed with conservative treatment. All patients were followed up for 12-56 months (median: 34 months) without any loss to follow-up. During the follow-up period, no complications, such as anastomotic stricture or stone formation, were observed. CONCLUSION The application of 3D visualization technology for preoperative evaluation and intraoperative navigation can accurately and effectively facilitate early surgical repair of bile duct injury during LC and has clinical value for promotion and application.

Abstract
BACKGROUND Distal bile duct carcinoma continues to be one of the most difficult cancers to manage in terms of staging and radical resection. Pancreaticoduodenectomy (PD) with regional lymph node dissection has become the standard treatment of distal bile duct carcinoma. We evaluated treatment outcomes and histological factors in patients with distal bile duct carcinoma. METHODS Seventy-four cases of resection of carcinoma of the distal bile ducts treated at our department during the period from January 2002 and December 2016 using PD and regional lymph node dissection as the standard surgical procedure were investigated. Survival rates of factors were analyzed using uni- and multivariate analyses. RESULTS The median survival time was 47.8 months. On univariate analysis, age of 70 years or older, histologically pap, pPanc2,3, pN1, pEM0, v2,3, ly2,3, ne2,3 and postoperative adjuvant chemotherapy were statistically significant factors. On multivariate analysis, histologically pap was identified as a significant independent prognostic factor. The multivariate analysis identified age of 70 years or older, pEM0, ne2,3 and postoperative adjuvant chemotherapy as showing a significant trend towards independent prognostic relevance. CONCLUSION The good news about resected distal bile duct carcinoma is that the percentage of those who achieved R0 resection has risen to 89.1%. Our multivariate analysis identified age of 70 years or older, pEM0, ne2,3 and postoperative adjuvant chemotherapy as prognostic factors. In order to improve the outcome of treatment, it is necessary to improve preoperative diagnostic imaging of pancreatic invasion and lymph node metastasis, establish the optimal operation range and clarify whether aortic lymph node dissection is needed to control lymph node metastasis, and establish effective regimens of chemotherapy.

Abstract
BACKGROUND Liver cancer resection is an effective but complex way to treat liver cancer, and complex anatomy is one of the reasons for the difficulty of surgery. The use of 3D technology can help surgeons cope with this dilemma. This article intends to conduct a bibliometric analysis of the role of 3D technology in liver cancer resection. METHODS (TS = (3D) OR TS = (three-dimensional)) AND (TS = (((hepatic) OR (liver)) AND ((cancer) OR (tumor) OR (neoplasm)))) AND (TS = (excision) OR TS = (resection)) was used as a search strategy for data collection in the Web of Science (WoS) Core Collection. CiteSpace, Carrot2 and Microsoft Office Excel were used for data analysis. RESULTS Three hundred and eighty-eight relevant articles were obtained. Their annual and journal distribution maps were produced. Countries/regions and institutions collaboration, author collaboration, references co-citations and their clusters and keywords co-occurrences and their clusters were constructed. Carrot2 cluster analysis was performed. CONCLUSIONS There was an overall upward trend in the number of publications. China's contribution was greater, and the USA had greater influence. Southern Med Univ was the most influential institution. However, the cooperation between institutions still needs to be further strengthened. Surgical Endoscopy and Other Interventional Techniques was the most published journal. Couinaud C and Soyer P were the authors with the highest citations and centrality, respectively. "Liver planning software accurately predicts postoperative liver volume and measures early regeneration" was the most influential article. 3D printing, 3D CT and 3D reconstruction may be the mainstream of current research, and augmented reality (AR) may be a future hot spot.

Radiological Shape of the Tumor Predicts Progression and Survival in Resected Extrahepatic Cholangiocarcinoma. J Gastrointest Surg 2023:10.1007/s11605-023-05614-y. [PMID: 36749559 DOI: 10.1007/s11605-023-05614-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Accepted: 01/27/2023] [Indexed: 02/08/2023]
Abstract
BACKGROUND The histological features and radiological shape of extrahepatic cholangiocarcinoma (eCCA) have not been widely studied in relation to prognosis. Multi-detector computed tomography (MDCT) is thought to be useful in diagnosis of progress and tumor distribution; it can also show morphological differences (round, triangular, and square forms) at the tumoral obstruction sites. Histological types of eCCA may be revealed, with potential association with tumor growth and survival. METHODS We examined the distribution of tumor radiological shape subtypes on MDCT. The surgical outcomes of consecutive patients with eCCA who underwent macroscopic curative resection were reviewed. RESULTS CT subtypes in 109 patients were 62 triangular, 35 square, and 12 round. There were clear prognostic differences in long-term survival rates (P < 0.001); 5-year survival rates were 100% in round, 64% in triangular, and 19% in square types. There was no recurrence in any cases of round-type tumor at the site of obstruction. Depth of tumor invasion and rates of nodal involvement were significantly higher in triangular and square-type tumors than in round-type tumors. In papillary adenocarcinoma, radiological obstructions were round type in seven patients (78%) and triangular type in two patients (22%). In tubular adenocarcinoma, all round-type tumors were well differentiated, the ratio of square-type tumors increasing as the degree of differentiation decreased from "well" to "moderate," and "poor" respectively (23%, 39%, 57%; P = 0.033). CONCLUSIONS Tumor radiological shape predicts tumor progression, histological type, and survival in eCCA. This information may be helpful in preoperative radiological staging on MDCT.

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
BACKGROUND Surgical resection is the only curative strategy for perihilar cholangiocarcinoma (PHC), but recurrence rates are high even after purported curative resection. This study aimed to evaluate the efficacy and safety of gemcitabine/S-1 (GS) combination chemotherapy in the neoadjuvant setting. METHODS In an open-label, single-arm, phase 2 study, neoadjuvant chemotherapy (NAC) with GS, repeated every 21 days, was administered for three cycles to patients with histologic or cytologically confirmed borderline resectable (BR) PHC who were eligible for inclusion in the study. In this study, BR PHC was defined as positive for lymph node metastasis and for cancerous vascular invasion or Bismuth type 4 on preoperative imaging. The primary end point consisted of the 3- and 5-year survival rates. The secondary end points were feasibility, resection rate, and pathologic effect. RESULTS The study enrolled 60 patients between January 2011 and December 2016. With respect to toxicity, the major adverse effect was neutropenia, which reached grade 3 or 4 in 53.3% of cases. The overall disease control rate was 91.3%. The median survival time for the entire cohort was 30.3 months. For all the patients, the estimated 3-year survival rate was 44.1%, and the 5-year survival rate was 30.0%. Resection with curative intent was performed for 43 (71%) of the 60 patients. For 81% of the resected patients, R0 resection was performed, and Clavien-Dindo grade 3 complications or a higher morbidity rate was seen in 41% of the patients. The median survival time was 50.1 months for the resected and 14.8 months for the unresected patients. For the resected patients, the estimated 3-year survival rate was 55.8%, and the estimated 5-year survival rate was 36.4%. CONCLUSIONS Gemcitabine/S-1 combination NAC has promising efficacy and good tolerability for patients with BR PHC.

Abstract
Objective To conduct a systematic literature review of imaging techniques and findings
in patients with peribiliary liver metastasis. Methods Several electronic datasets were searched from January 1990 to June 2017 to
identify studies assessing the use of different imaging techniques for the
detection and staging of peribiliary metastases. Results The search identified 44 studies, of which six met the inclusion criteria and
were included in the systematic review. Multidetector computed tomography
(MDCT) is the technique of choice in the preoperative setting and during the
follow-up of patients with liver tumors. However, the diagnostic performance
of MDCT for the assessment of biliary tree neoplasms was low compared with
magnetic resonance imaging (MRI). Ultrasound (US), without and with contrast
enhancement (CEUS), is commonly employed as a first-line tool for evaluating
focal liver lesions; however, the sensitivity and specificity of US and CEUS
for both the detection and characterization are related to operator
expertise and patient suitability. MRI has thus become the gold standard
technique because of its ability to provide morphologic and functional data.
MRI showed the best diagnostic performance for the detection of peribiliary
metastases. Conclusions MRI should be considered the gold standard technique for the radiological
assessment of secondary biliary tree lesions.

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
BACKGROUND The Japanese Society of Hepato-Biliary-Pancreatic Surgery launched the clinical practice guidelines for the management of biliary tract cancers (cholangiocarcinoma, gallbladder cancer, and ampullary cancer) in 2007, then published the 2nd version in 2014. METHODS In this 3rd version, clinical questions (CQs) were proposed on six topics. The recommendation, grade for recommendation, and statement for each CQ were discussed and finalized by an evidence-based approach. Recommendations were graded as Grade 1 (strong) or Grade 2 (weak) according to the concepts of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. RESULTS The 31 CQs covered the six topics: (a) prophylactic treatment, (b) diagnosis, (c) biliary drainage, (d) surgical treatment, (e) chemotherapy, and (f) radiation therapy. In the 31 CQs, 14 recommendations were rated strong and 14 recommendations weak. The remaining three CQs had no recommendation. Each CQ includes a statement of how the recommendations were graded. CONCLUSIONS This latest guideline provides recommendations for important clinical aspects based on evidence. Future collaboration with the cancer registry will be key for assessing the guidelines and establishing new evidence.

Three-dimensional versus two-dimensional video-assisted hepatectomy for liver disease: a meta-analysis of clinical data. Wideochir Inne Tech Maloinwazyjne 2020; 16:1-9. [PMID: 33786111 PMCID: PMC7991933 DOI: 10.5114/wiitm.2020.100678] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2020] [Accepted: 08/04/2020] [Indexed: 12/21/2022] Open
Abstract
Introduction The benefit of three-dimensional (3D) visualization for liver disease is uncertain. Aim To evaluate the effectiveness and safety of 3D versus two-dimensional (2D) video-assisted hepatectomy for LD. Material and methods We searched PubMed, Embase, Cochrane Library, Medline, and Web of Science for studies addressing 3D versus 2D for 2D until 30 February 2020. Study-specific effect sizes and their 95% confidence intervals (CIs) were combined to calculate the pooled value using a fixed-effects or random-effects model. Results Nine studies with 808 patients were included. The 3D group had shorter operative time (mean difference (MD) = 34.39; 95% CI = 59.50, 9.28), experienced less intraoperative blood loss (MD = 106.55; 95% CI = 183.76, 29.34), and a smaller blood transfusion volume (MD = 88.25; 95% CI = 141.26, 35.24). The 3D group had a smaller difference between the predicted volume and the actual resected volume (MD = 103.25; 95% CI = 173.24, 33.26) and a lower rate of postoperative complications (odds ratio (OR) = 0.57; 95% CI: 0.35, 0.91). Conclusions During surgery, 3D video-assisted hepatectomy could effectively reduce operative time, intraoperative bleeding, and blood transfusion volume, and had a smaller difference between the predicted volume and the actual resected volume and a lower rate of postoperative complications. More high-quality randomized controlled trials are required to verify the reliability and validity of our conclusion.

Abstract
BACKGROUND Patients with strangulating small bowel obstructions (SBOs) can rapidly deteriorate, in condition; therefore, immediate and appropriate diagnosis is required. However, some cases of SBO are difficult to diagnose using axial computed tomography (CT) images alone. The impact of 3D vessel imaging for the diagnosis, surgical indication, and timing of strangulating SBOs was investigated, prospectively. METHODS Clinical data were collected for 111 strangulating SBOs and 48 simple SBOs from patients receiving surgical interventions from January 2009 to March 2018. The accuracy of preoperative diagnoses for the type of SBO was evaluated. Among 159 patients, 27 underwent contrast-enhanced CT imaging as well as prospectively reconstructed 3D vessel imaging of the superior mesenteric artery, vein, and branches. The concordance rate of operative findings and preoperative diagnoses of the type of SBO were compared between axial CT imaging alone and combination of axial and 3D vessel imaging. RESULTS Overall concordance rate of diagnosis for the type of SBO by axial imaging was 93.1% and that of strangulating and simple SBOs was 92.8% and 93.8%, respectively. Combined axial and 3D vessel imaging resulted in 100% accuracy of preoperative diagnoses for both types of SBO. In addition, abnormalities could be classified from 3D vessel images as central twists or peripheral twists, and deteriorated vascular flow could also be detected. CONCLUSIONS The combination of axial imaging and 3D vessel imaging can be used to accurately diagnose SBOs, and this imaging technique may be useful for determining the surgical indication and suitable timing of strangulating SBOs.

Abstract
BACKGROUND The concept of "borderline resectable" was recently introduced to the field of surgery for pancreatic cancer, and surgical outcomes for this disease with extremely dismal prognosis have improved since the introduction of this concept. However, no such concept has yet been introduced to the field of surgery for hilar cholangiocarcinoma (HCca). AIM To determine a definition and criteria for "borderline resectable" in the field of surgery for HCca. PATIENTS AND METHODS Retrospective analysis of 88 patients undergoing curative-intent surgery for HCca at our institution between May 1992 and December 2008 to clarify independent prognostic factors. RESULTS Survival outcomes were obtained for these 88 patients, with a 5-year overall survival rate of 31.8%. Independent factors predictive of cancer death were determined by multivariate analysis to be the presence of regional lymph node metastasis (LNM) and pathological confirmed vascular invasion (VI). Cumulative survival rates of 23 patients with both LNM and VI who underwent surgery were significantly worse than those of the remaining 65 surgically treated patients and similar to those of 26 patients who were considered to have unresectable disease and treated with non-surgical multidisciplinary treatment during the same study period. CONCLUSION Outcomes of surgery for cases of HCca showing regional LNM and VI were no better than those of non-surgical treatment for unresectable disease. Coexistence of these two factors indicates oncologically dismal condition and thus such cases should be considered "borderline resectable." Treatments additional to surgery are required for "borderline resectable" cases to obtain better outcomes.

Abstract
BACKGROUND We sought to expand the clinico-anatomical limit of the proximal ductal margin (Limit-PDM) for resectability of hilar cholangiocarcinoma (HCCA). METHODS The practical boundary of the hilar plate (PBHP) was defined as the location where the bile duct (BD) could not be isolated by dissection. The distance between PBHP and two well-known clinical landmarks of Limit-PDM, the right edge of the bifurcation of the anterior and posterior branch of the right portal vein (Posterior-Landmark) and the left edge of the umbilical portion of the portal vein (Left-Landmark), and histological features around the PBHP were assessed using 55 adult cadaver livers. RESULTS BD was almost always isolatable beyond the traditional clinical landmarks. The median distance was 6.9 mm (interquartile range [IQR] 6.0-8.3 mm) between the PBHP and the Posterior-Landmark, and 8.9 mm (IQR 6.7-10.2 mm) between the PBHP and the Left-Landmark. Histologically, the sheath surrounding the portal triad was loose, thick with few elastic fibers and small arteries near the hepatic hilum. Near the PBHP, the sheath was dense, thin, and abundant with elastic fibers and small arteries. CONCLUSIONS Limit-PDM is more peripheral than the traditional clinical landmark-based margin and histological transition near the PBHP was revealed.

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
The 30th meeting of the JSHBPS is the first domestic meeting of our society to have been organized completely in English. In that sense, we have established the theme of the 30th meeting of the JSHBPS as "The Second Opening of Japan on the Way to a Bright Future". Last 30 years, several strategies have been undertaken to battle hepatobiliary (HPB) malignancies, such as aggressive operative procedures, operative planning using state-of-the-art technologies, neoadjuvant therapy, conversion surgery for initially unresectable diseases, and immunomodulation. According to the rapid development of precision medicine, HBP surgeons should have a literacy for individualized therapy. Here, I review recent improvements in regard to HBP surgery. In addition, education for the next generations should be our highest priority. Collaboration with foreign researchers is the most effective tool to promote personal growth.

Modification and establishment of CT criteria in preoperative assessment of portal venous invasion by hilar cholangiocarcinoma. HPB (Oxford) 2018; 20:1163-1171. [PMID: 30030081 DOI: 10.1016/j.hpb.2018.05.013] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2018] [Revised: 05/09/2018] [Accepted: 05/19/2018] [Indexed: 12/12/2022]
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
The aim of the present study was to examine the utility of convex endoscopic ultrasonography (EUS) for the preoperative vascular evaluation of malignant biliary tract neoplasm, by comparing EUS findings with histological findings from resected specimens. Between January 2008 and January 2016, the present study retrospectively retrieved 82 cases diagnosed with malignant biliary tract neoplasm to compare findings from convex EUS with histological findings from resected specimens. A total of four groups were defined according to the results of EUS of the hepatic artery (HA) and portal vein (PV): Group 1, hyperechoic tissue between tumor and vessel; group 2, close proximity between tumor and vessel without loss of hyperechoic tissue; group 3, tumor and vessel contiguity, with loss of hyperechoic tissue; and group 4, encasement >180°. Regarding the HA, all 17 cases in groups 2 and 3 in which the tumor was close to the HA however no obvious encasement was evident, demonstrated no histological invasion, or the HA could be separated from the tumor intraoperatively. However, this was not the case for the portal vein. Of the six cases in group 3, 4 cases (66.7%) demonstrated PV invasion. Overall, convex EUS is useful for the preoperative evaluation of malignant biliary tract neoplasms, and surgery may be considered when the tumor is close to the HA on computed tomography scans, however there is no obvious encasement visualized by convex EUS.

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
Right-sided ligamentum teres (RSLT) is a rare congenital anomaly often accompanied by variation of the hepatic vasculature. We herein report a surgical case of a hilar cholangiocarcinoma with RSLT in whom preoperative hepatectomy simulation proved useful for understanding the anatomical structure of the liver. A 78-year-old male with obstructive jaundice was referred to our department for further examination. The patient was suspected of having a hilar cholangiocarcinoma originating from the left hepatic bile duct by contrast-enhanced computed tomography (CT), and CT also showed right umbilical portion (RUP). Three-dimensional images of the hepatic vasculature and biliary system reconstructed using a hepatectomy simulation system suggested that all portal branches ramified from RUP were right paramedian branches, and three leftward portal branches from these ran parallel to the peripheral bile ducts confluent with the left hepatic bile duct, where the tumor was present. Hepatic resection of part of the ventral area of the right paramedian sector and left hemiliver was performed along the demarcation line drawn after clamping the portal branches; the ratio of estimated liver resection volume was 28.9%. After the operation, bile leakage occurred. However, the leakage was treated with percutaneous drainage alone, and the patient was discharged 77 days after the operation. The patient is doing well without any signs of recurrence 21 months after the operation. The vascular and biliary anatomy in patients with RSLT is complicated and should be evaluated in detail preoperatively using a hepatectomy simulation system.

Impact of Preoperative Three-Dimensional Computed Tomography Cholangiography on Postoperative Resection Margin Status in Patients Operated due to Hilar Cholangiocarcinoma. Gastroenterol Res Pract 2017; 2017:1947023.

Abstract
INTRODUCTION The purpose of this study was to analyse the value of 3-dimensional computed tomography cholangiography (3D-ERC) compared to conventional retrograde cholangiography in the preoperative diagnosis of hilar cholangiocarcinoma (HC) with special regard to the resection margin status (R0/R1). PATIENTS AND METHODS All hepatic resections performed between January 2011 and November 2013 in patients with HC at the Department of General, Visceral and Transplant Surgery of the RWTH Aachen University Hospital were analysed. All patients underwent an ERC and contrast-enhanced multiphase CT scan or a 3D-ERC. RESULTS The patient collective was divided into two groups (group ERC: n = 17 and group 3D-ERC: n = 16). There were no statistically significant differences between the two groups with regard to patient characteristics or intraoperative data. Curative liver resection with R0 status was reached in 88% of patients in group ERC and 87% of patients in group 3D-ERC (p = 1.00). We could not observe any differences with regard to postoperative complications, hospital stay, and mortality rate between both groups. CONCLUSION Based on our findings, preoperative imaging with 3D-ERC has no benefit for operative planning and R0 resection status. It cannot replace the exploration by an experienced surgeon in a centre for hepatobiliary surgery.

Abstract
Portal vein tumor thrombus (PVTT) usually worsens prognosis of hepatocellular carcinoma (HCC), as characterized by aggressive disease progression, impaired liver function and tolerance to treatment. Conventionally, the European Association for the Study of the Liver (EASL) and the American Association for the Study of Liver Diseases (AASLD) accepted the Barcelona Clinical Liver Cancer (BCLC) treatment algorithms, identifying PVTT as an absolute contra-indication of surgical resection for HCC. HCC-PVTT patients are offered sorafenib as the standard treatment. Evidently, SHARP and Asia-Pacific trials demonstrated that sorafenib only improves overall survival by approximately 3 months in patients with advanced HCC. Besides, BCLC treatment algorithm does not provide different therapeutic recommendations for different degree of PVTT, and only supports single treatment option for each stage of HCC rather than a combination of comprehensive treatments, which limited individual and best care for every HCC-PVTT patients. In the past few years, many surgeons do not restrict surgical resection to HCC with PVTT. There have been new reports demonstrated that surgical treatment is feasible for selected HCC-PVTT patients with resectable tumor and moderate liver function to prolong survival period and elevate life quality as long as PVTT limited to the first-order branch, whereas non-surgical treatments fail to provide comparable therapeutic effects. At present, guidelines on HCC management from mainland China, Japan, and Hong Kong have been updated and a consensus of Asia-Pacific experts has established that portal venous invasion is not an absolute contradiction of surgical resection for HCC. This review summarized the emerging data on surgical resection for HCC-PVTT patients beyond the BCLC treatment algorithms and discussed recent therapeutic conceptualchanges in the Asia-Pacific region.

Abstract
BACKGROUND Preoperative evaluation of vasculobiliary anatomy in the umbilical fissure (U-point) is pivotal for perihilar cholangiocarcinoma (PCCA) applied to right-sided hepatectomy. The purpose of our study was to review the vasculobiliary anatomy in the U-point using three-dimensional (3D) reconstruction technique, to investigate the diagnostic ability of 2D scans to evaluate anatomic variations, and to discuss its surgical implications. METHODS A retrospective study of 159 patients with Bismuth type I, II, and IIIa PCCA, who received surgery at our institution from November 2012 to September 2016, was conducted. Anatomic structures were assessed using multidetector computed tomography (MDCT) by one hepatobiliary surgeon, whereas 3D images were reconstructed by an independent radiologist. Normal confluence pattern of left biliary system was defined as the left medial segmental bile duct (B4) joining the common trunk of segment II (B2) and segment III (B3) ducts, whereas aberrant confluence patterns were classified into 3 types: type I, triple confluence of B2, B3, and B4; type II, B2 draining into the common trunk of B3 and B4; type III, other patterns. Surgical anatomy of B4 was classified into the central, peripheral, and combined type according to its relation to the hepatic confluence. The lengths from the bile duct branch of Spiegel's lobe (B1l) to the orifice of B4 and the junction of B2 and B3 were measured on 3D images. The anatomy of left hepatic artery (LHA) was classified according to different origins and the spatial relationship related to the U-point. RESULTS 3D reconstruction revealed that normal confluence pattern of left biliary system was observed in 71.1% (113/159) of all patients, and variant patterns were type I in 11.9% (19/159), type II in 12.6% (20/159), and type III in 4.4% (7/159). The length from B1l to the junction of B2 and B3 was 12.1 ± 3.1 mm in type I variation, which was significantly shorter than that in normal configuration (30.0 ± 6.8 mm, P < 0.001) but significantly longer than that in type II variation (9.6 ± 3.4 mm, P = 0.019). Surgical anatomy of B4: the peripheral type was most commonly seen (74.2%, 118/159), followed by central type (15.7%, 25/159) and combined type (10.1%, 16/159). The distance between the B1l and B4 was 8.4 ± 2.4 mm in central and combined type, which was significantly shorter than that in peripheral type (14.5 ± 4.1 mm, P < 0.001). A replaced or accessory LHA from the left gastric artery was present in 6 (3.8%) and 9 (5.7%) patients, respectively. LHA running along the left caudal position of U-point was present in 143 cases (89.9%), along the right cranial position of U-point in nine cases (5.7 %), and combined position in seven cases (4.4%). Interobserver agreement of two imaging modalities was almost perfect in biliary confluence pattern (kappa = 0.90; 95% confidence interval: 0.79-1.00), substantial in surgical anatomy of B4 (kappa = 0.74; 95% confidence interval: 0.62-0.86), and perfect in LHA (kappa = 1.00). CONCLUSIONS Thoroughly understanding the imaging characters of surgical anatomy in the U-point may be benefit for preoperative evaluation of PCCA by successive review of 2D images alone, whereas 3D reconstruction technique allows detailed hepatic anatomy and individualized surgical planning for advanced cases.

Abstract
To perform accurate hepatectomy without injury, it is necessary to understand the anatomical relationship among the branches of Glisson's sheath, hepatic veins, and tumor. In Japan, three-dimensional (3D) preoperative simulation for liver surgery is becoming increasingly common, and liver 3D modeling and 3D hepatectomy simulation by 3D analysis software for liver surgery have been covered by universal healthcare insurance since 2012. Herein, we review the history of virtual hepatectomy using computer-assisted surgery (CAS) and our research to date, and we discuss the future prospects of CAS. We have used the SYNAPSE VINCENT medical imaging system (Fujifilm Medical, Tokyo, Japan) for 3D visualization and virtual resection of the liver since 2010. We developed a novel fusion imaging technique combining 3D computed tomography (CT) with magnetic resonance imaging (MRI). The fusion image enables us to easily visualize anatomic relationships among the hepatic arteries, portal veins, bile duct, and tumor in the hepatic hilum. In 2013, we developed an original software, called Liversim, which enables real-time deformation of the liver using physical simulation, and a randomized control trial has recently been conducted to evaluate the use of Liversim and SYNAPSE VINCENT for preoperative simulation and planning. Furthermore, we developed a novel hollow 3D-printed liver model whose surface is covered with frames. This model is useful for safe liver resection, has better visibility, and the production cost is reduced to one-third of a previous model. Preoperative simulation and navigation with CAS in liver resection are expected to help planning and conducting a surgery and surgical education. Thus, a novel CAS system will contribute to not only the performance of reliable hepatectomy but also to surgical education.

Abstract
BACKGROUND Since biliary variations are commonly seen, our aims are to clarify these insidious variations and discuss their surgicopathologic implications for Bismuth-Corlette (BC) type IV hilar cholangiocarcinoma (HC) applied to hemihepatectomy. METHODS Three-dimensional images of patients with distal bile duct obstruction (n = 97) and advanced HC (n = 79) were reconstructed and analyzed retrospectively. Normal biliary confluence pattern was defined as the peripheral segment IV duct (B4) joining the common trunk of segment II (B2) and segment III (B3) ducts to form the left hepatic duct (LHD) that then joined the right hepatic duct (RHD). The lengths from left and right secondary biliary ramifications to the right side of the umbilical portion of the left portal vein (Rl-L) and the cranio-ventral side of the right portal vein (Rr-R) were measured, respectively, and compared with the resectable bile duct length in HCs. Surgicopathologic findings were compared between different BC types. RESULTS The resectable bile duct length in right hemihepatectomy for eradication of type IV tumors was significantly longer than the Rl-L length in normal biliary configuration (17.4 ± 1.8 and 10.3 ± 3.4 mm, respectively, p < 0.001), and type III variation (B2 joining the common trunk of B3 and B4) was the predominant configuration (53.8%). The resectable length in left hemihepatectomy for eradication of type IV tumors was comparable with the Rr-R length in RHD absent cases (15.2 ± 2.5 and 16.4 ± 2.6 mm, respectively, p = 0.177) but significantly longer than that in normal configuration (p < 0.001). The estimated length was 8.5 ± 2.0 mm in unresectable cases. There was no significant difference between type III and IV tumors, except for the rate of nodal metastasis (29.7 and 76.0%, respectively, p < 0.001). CONCLUSION Hemihepatectomy might be selected for curative-intent resection of BC type IV tumors considering the advantageous biliary variations, whereas anatomical trisegmentectomy is recommended for the resectable bile duct length less than 10 mm. Biliary variations might result in excessive classification of BC type IV but require validation on further study.

Abstract
Primary liver cancer is the fifth most common cancer worldwide. Apart from liver transplantation, surgical resection has been accepted as the effective local treatment for hepatocellular carcinoma (HCC), one of the most common primary liver cancers. Recent technological innovations including navigation technology and intraoperative real-time fluorescence guidance have been utilized for liver resections in clinical practice. With respect to liver resection techniques, the laparoscopic approach has been increasingly gaining popularity as one of the minimally-invasive treatments of HCC. These technological innovations and technical advancements are expected to further improve the safety and efficacy of liver resections.

Abstract
BACKGROUND AND STUDY AIMS Neoadjuvant chemotherapy (NAC) may lead to a successful margin-negative resection in patients with initially unresectable locally advanced Klatskin tumor (IULAKT). Use of removable plastic stents is preferable for the safe implementation of NAC in patients with IULAKT to reduce the risk of recurrent cholangitis. Our aim was to evaluate the efficacy associated with the use of plastic stents placed across the stenosis and above the papilla (above stent) during NAC. PATIENTS AND METHODS In this study, we stratified the patients into two groups chronologically with respect to the period of stent placement: above stent group (n = 17) and across stent group (n = 23) (plastic stent across the sphincter of Oddi). RESULTS The median stent patency period was 99 days in the above stent group and 31 days in the across stent group (P < 0.0001). The number of stents (P = 0.017) and the rate of emerging undrained cholangitis areas (P = 0.025) were significantly reduced in the above stent group than the counterpart. Regarding time to recurrent biliary obstruction, the above stent group had a longer duration than the across stent group (log rank test, P = 0.004). Length of hospital stay was significantly shorter for the above stent group than the across stent group (P = 0.0475). Multivariate analysis revealed that above stent placement (odds ratio = 33.638, P = 0.0048) was significantly associated with stent patency over a period of 90 days. CONCLUSIONS Above stent placement should be considered for the relief of biliary obstruction and potentially reduces the cost for patients with IULAKT scheduled to receive NAC.

Abstract
BACKGROUND Accurate assessment of characteristics of tumor and portal vein tumor thrombus is crucial in the management of hepatocellular carcinoma. AIMS Comparison of the three-dimensional imaging with multiple-slice computed tomography in the diagnosis and treatment of hepatocellular carcinoma with portal vein tumor thrombus. METHOD Patients eligible for surgical resection were divided into the three-dimensional imaging group or the multiple-slice computed tomography group according to the type of preoperative assessment. The clinical data were collected and compared. RESULTS 74 patients were enrolled into this study. The weighted κ values for comparison between the thrombus type based on preoperative evaluation and intraoperative findings were 0.87 for the three-dimensional reconstruction group (n = 31) and 0.78 for the control group (n = 43). Three-dimensional reconstruction was significantly associated with a higher rate of en-bloc resection of tumor and thrombus (P = 0.025). Using three-dimensional reconstruction, significant correlation existed between the predicted and actual volumes of the resected specimens (r = 0.82, P < 0.01), as well as the predicted and actual resection margins (r = 0.97, P < 0.01). Preoperative three-dimensional reconstruction significantly decreased tumor recurrence and tumor-related death, with hazard ratios of 0.49 (95% confidential interval, 0.27-0.90) and 0.41 (95% confidential interval, 0.21-0.78), respectively. CONCLUSION For hepatocellular carcinoma with portal vein tumor thrombus, three-dimensional imaging was efficient in facilitating surgical treatment and benefiting postoperative survivals.

Abstract
Background A detailed evaluation of blood supply anatomy, especially the biliary anatomy at the hepatic hilus, is essential to ensure a complete and curative resection for Bismuth and Corlette type III hilar cholangiocarcinoma. The study aimed to investigate the impact of individualized preoperative planning using 3D modeling on surgical treatment for type III hilar cholangiocarcinoma. Methods This was a retrospective study of patients with type III hilar cholangiocarcinoma (n = 47) who underwent surgery at the Hepatobiliary Surgery Department of Zhujiang Hospital between March 2007 and January 2015. All patients had undergone preoperative computed tomography (CT) examination, and 3D images were reconstructed. Preoperative surgery simulation was performed, and the simulation was applied in the subsequent surgery. Clinical, surgical, and pathological characteristics were compared between patients undergoing preoperative planning (n = 25) and those who did not (n = 22). Complications were examined. Results Surgical time and blood loss were significantly smaller in patients with 3D reconstruction compared to those without. The number of bile duct orifices was correctly estimated in 14/25 (56.0 %) patients with preoperative planning. The width of the hepatic surgical margin could be measured for 18 hepatic ducts, and 17 (68.0 %) of them were pathologically diagnosed as margin-negative. Conclusions This technique has the advantages of precise visualization of the anatomic structures and 3D assessment of biliary branches and vessels, allowing improved operative planning for the treatment of hilar cholangiocarcinoma.

[PMID: 26379403 PMCID: PMC4566391 DOI: 10.3748/wjg.v21.i34.9982] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2015] [Revised: 05/07/2015] [Accepted: 07/03/2015] [Indexed: 02/06/2023] Open
Abstract
AIM: To develop a novel 3-dimensional (3D) virtual hepatectomy simulation software, Liversim, to visualize the real-time deformation of the liver.
METHODS: We developed a novel real-time virtual hepatectomy simulation software program called Liversim. The software provides 4 basic functions: viewing 3D models from arbitrary directions, changing the colors and opacities of the models, deforming the models based on user interaction, and incising the liver parenchyma and intrahepatic vessels based on user operations. From April 2010 through 2013, 99 patients underwent virtual hepatectomies that used the conventional software program SYNAPSE VINCENT preoperatively. Between April 2012 and October 2013, 11 patients received virtual hepatectomies using the novel software program Liversim; these hepatectomies were performed both preoperatively and at the same that the actual hepatectomy was performed in an operating room. The perioperative outcomes were analyzed between the patients for whom SYNAPSE VINCENT was used and those for whom Liversim was used. Furthermore, medical students and surgical residents were asked to complete questionnaires regarding the new software.
RESULTS: There were no obvious discrepancies (i.e., the emergence of branches in the portal vein or hepatic vein or the depth and direction of the resection line) between our simulation and the actual surgery during the resection process. The median operating time was 304 min (range, 110 to 846) in the VINCENT group and 397 min (range, 232 to 497) in the Liversim group (P = 0.30). The median amount of intraoperative bleeding was 510 mL (range, 18 to 5120) in the VINCENT group and 470 mL (range, 130 to 1600) in the Liversim group (P = 0.44). The median postoperative stay was 12 d (range, 6 to 100) in the VINCENT group and 13 d (range, 9 to 21) in the Liversim group (P = 0.36). There were no significant differences in the preoperative outcomes between the two groups. Liversim was not found to be clinically inferior to SYNAPSE VINCENT. Both students and surgical residents reported that the Liversim image was almost the same as the actual hepatectomy.
CONCLUSION: Virtual hepatectomy with real-time deformation of the liver using Liversim is useful for the safe performance of hepatectomies and for surgical education.

Radiological Imaging for Assessing the Respectability of Hilar Cholangiocarcinoma: A Systematic Review and Meta-Analysis. BIOMED RESEARCH INTERNATIONAL 2015; 2015:497942. [PMID: 26448940 PMCID: PMC4569758 DOI: 10.1155/2015/497942] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/13/2015] [Revised: 07/26/2015] [Accepted: 07/28/2015] [Indexed: 02/05/2023]
Abstract
Hilar cholangiocarcinoma (HCC) remains one of the most difficult tumors to stage and treat. The aim of the study was to assess the diagnostic efficiency of computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography/computer tomography (PET/CT) in evaluating the resectability of HCC. A systematic search was performed of the PubMed, EMBASE, and Cochrane databases. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy were calculated for individual studies and pooled data as well as test for heterogeneity and public bias. Our data showed that CT had the highest pooled sensitivity at 95% (95% CI: 91–97), whereas PET/CT had the highest pooled specificity at 81% (95% CI: 69–90). The area under the curve (AUC) of CT, MRI, and PET/CT was 0.9269, 0.9194, and 0.9218, respectively. In conclusion, CT is the most frequently used imaging modality to assess HCC resectability with a good sensitivity and specificity. MRI was generally comparable with that of CT and can be used as an alternative imaging technique. PET/CT appears to be the best technique in detecting lymph node and distant metastasis in HCC but has no clear role in helping to evaluate issues of local resectability.

Abstract
BACKGROUND Full understanding of the hilar anatomy is crucial for successful surgical resection of perihilar cholangiocarcinoma (PHC). METHODS The three-dimensional positional relationship between the left hepatic artery (LHA) and the umbilical portion of the left portal vein (UP) was evaluated using multidetector-row computed tomography (CT) in 58 consecutive patients who underwent right-sided hepatectomy for Bismuth-Corlette IIIa or IV tumors. The positional relationship of the LHA related to UP was classified into the following three types: L-UP type, LHA runs into the left lateral section (LLS) from the left caudal side of the UP; R-UP type, LHA runs into the LLS from the right cranial side of the UP; and combined type, one branch of the LHA runs into the LLS from the right cranial side of the UP, and the other from the left caudal side of the UP. RESULTS L-UP-type LHA was observed in 53 cases (91.4 %), R-UP type in three cases (5.2 %), and combined type in two cases (3.4 %). No cancer involvement of the LHA was seen in any cases with L-UP type. In one case with R-UP type (one of three; 33.3 %) and one case with combined type (one of two, 50 %), cancer invasion to the LHA was observed at the right side of the UP, requiring combined resection of the involved LHA. CONCLUSIONS R-UP-type LHA running just along the left hepatic duct may be easily involved by right-side predominant PHC when extending to the left hepatic duct. Hepatobiliary surgeons should recognize this anatomical variant and carefully evaluate the running courses of LHA to successfully perform R0 resection in right-sided hepatectomy for PHC.

Abstract
BACKGROUND The complexity of hepatic hilar anatomy is an obstacle to precise diagnosis of tumor spread and appropriate operative planning for biliary malignancies. Three-dimensional (3D) cholangiography and angiography may overcome this obstacle and facilitate curative resection. The objective of this study was to evaluate the impact of 3D CT cholangiography on operative planning and outcomes of biliary malignancies. METHODS From 2009 to 2014, 3DCT cholangiography was performed on 49 patients with biliary malignancies requiring major hepatic resection and extrahepatic bile duct resection. The 3D cholangiogram was merged with 3D angiography and portography to create an all-in-one 3D image of the hepatic hilum. The cutting line of the bile duct and the type of liver resection were determined based on the spatial relationship between tumor spread and the landmark vessels. The necessity of vascular reconstruction was also evaluated. Preoperative imaging and operative findings were compared. Operative curability was compared with that of the historical cohort before the introduction of 3D cholangiography. RESULTS Histologic examination of the bile duct stump showed a negative margin in 39 (80%), carcinoma in situ in 7 (14%), and invasive cancer (IC) in 3 patients (6%) on the first cutting. The IC-free rate (94%) on the first cutting was superior to that in the historical cohort (80%; P = .02). The necessity for portal and arterial reconstruction was predicted with 98 and 94% accuracy, respectively. CONCLUSION We found 3D cholangiography to provide accurate information about hilar anatomy and plays a role in facilitating adequate operative planning.

Abstract
The first separate staging system for perihilar cholangiocarcinoma was introduced by the seventh edition American Joint Committee on Cancer (AJCC) manual. To determine whether it strengthens the prognostic value, a comparative analysis with the sixth edition was performed, through which some areas for improvements were identified. The tumor-nodes-metastasis (TNM) stage and R status of 378 operated perihilar cholangiocarcinoma patients between 1990 and 2011 were reviewed. Survival analyses were conducted. Although the stages were up-numbered from I to II and II to III, the sixth and seventh editions had intercorresponding stages providing similar classifications. Applying the seventh edition, 9.8% were downstaged and 1.3% upstaged. Several issues were identified. First, both editions did not discriminate node-free locally advanced resectable diseases and node-positive resectable diseases. Second, stages IVA and IVB in the seventh edition had different prognoses suggesting misclassification of stage IVA. Third, the prognosis of liver invasion (T2b) resembled that of T3 more than T2a in the seventh edition, warranting investigation into the downstaging of liver invasion. Lastly, curative resections were possible in some Bismuth type 4 tumors allowing for better survival, suggesting that classifying them as unresectable disease (T4) should be revised. A discrete staging for perihilar cholangiocarcinoma is necessary; however, some points need further clarifications.

Abstract
The purpose of radiological imaging in patients with suspected or known cholangiocarcinoma (CCA) is tumour detection, lesion characterization and assessment of resectability. Different imaging modalities are implemented complementary in the diagnostic work-up. Non-invasive imaging should be performed prior to invasive biliary procedures in order to avoid false positive results. For assessment of intraparenchymal tumour extension and evaluation of biliary and vascular invasion, MRI including MRCP and CT are the primarily used imaging modalities. The role of PET remains controversial with few studies showing benefit with the detection of unexpected metastatic spread, the differentiation between benign and malignant biliary strictures, and for discriminating post therapeutic changes and recurrent CCA.

Abstract
BACKGROUND The Japanese Society of Hepato-Biliary-Pancreatic Surgery launched the clinical practice guidelines for the management of biliary tract and ampullary carcinomas in 2008. Novel treatment modalities and handling of clinical issues have been proposed after the publication. New approaches for editing clinical guidelines, such as the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system, also have been introduced for better and clearer grading of recommendations. METHODS Clinical questions (CQs) were proposed in seven topics. Recommendation, grade of recommendation and statement for each CQ were discussed and finalized by evidence-based approach. Recommendation was graded to grade 1 (strong) and 2 (weak) according to the concept of GRADE system. RESULTS The 29 CQs covered seven topics: (1) prophylactic treatment, (2) diagnosis, (3) biliary drainage, (4) surgical treatment, (5) chemotherapy, (6) radiation therapy, and (7) pathology. In 27 CQs, 19 recommendations were rated strong and 11 recommendations weak. Each CQ included the statement of how the recommendation was graded. CONCLUSIONS This guideline provides recommendation for important clinical aspects based on evidence. Future collaboration with cancer registry will be a key for assessment of the guidelines and establishment of new evidence. Free full-text articles and a mobile application of this guideline are available via http://www.jshbps.jp/en/guideline/biliary-tract2.html.

Abstract
Optimal treatment of hilar cholangiocarcinoma depends on location of the cancer and extent of biliary and vascular involvement. Candidates for resection or transplantation must be evaluated and managed by a multidisciplinary team at a high-volume hepatobiliary center. Success requires absence of distant nodal or extrahepatic metastases and an adequate functional liver remnant with a negative ductal margin. Ipsilateral portal vein resection and reconstruction should be performed in patients with venous involvement. Neoadjuvant chemoradiation and liver transplantation is the best treatment option for patients with unresectable hilar cholangiocarcinoma without nodal or distant metastases and for patients with underlying chronic liver disease.

Abstract
Our objective was to investigate the application of three-dimensional (3D) stereoscopic volume rendering with perceptual colorization on preoperative imaging for malignant pleural mesothelioma. At present, we have prospectively enrolled 6 patients being considered for resection of malignant pleural mesothelioma that have undergone a multidetector-row computed tomography (CT) scan of the chest. The CT data sets were volume rendered without preprocessing. The resultant 3D rendering was displayed stereoscopically and used to provide information regarding tumor extent, morphology, and anatomic involvement. To demonstrate this technique, this information was compared with the corresponding two-dimensional CT grayscale axial images from two of these patients. Three-dimensional stereoscopic reconstructions of the CT data sets provided detailed information regarding the local extent of tumor that could be used for preoperative surgical planning. Three-dimensional stereoscopic volume rendering for malignant pleural mesothelioma is a novel approach. Combined with our innovative perceptual colorization algorithm, stereoscopic volumetric analysis potentially allows for the accurate determination of the extent of pleural mesothelioma with results difficult to duplicate using grayscale, multiplanar CT images.

Abstract
PURPOSE The aim of this study was to clarify the location of termination of the ligamentum venosum (LV) and topographic relationships between the left portal vein (LPV), left hepatic artery (LHA), and LV in the fissures for ligamentum teres and LV. METHODS Anatomical examination was performed on 50 livers from embalmed Korean adult cadavers. RESULTS The LV originated from a point between the transverse and umbilical portions of LPV (Tr-Um point) in all specimens, and terminated in the common trunk of the middle hepatic vein and left hepatic vein (LHV) (61%) or in the LHV (39%). In the fissures for ligamentum teres and LV, the courses of the LHA relative to the LV and the LPV varied, such that four main patterns could be discerned. In type I (48%), the LHA crossed the inferior surface of Tr-Um point and passed just left of the origin of LV. In type II (20%), the LHA crossed the inferior surface of umbilical portion of LPV. In type III (10%), the LHA crossed the inferior surface of Tr-Um point to pass just left of origin of LV, with one branch of the right hepatic artery crossing the inferior surface of umbilical portion of LPV. In type IV (12%), no arterial branches ran on the inferior surfaces of transverse and umbilical portions of LPV. CONCLUSION These details may play a role as external landmarks for facilitating preestimation of intrahepatic structures during various surgical procedures involving the liver.

Abstract
Purpose Extended liver resection may provide long-term survival in selected patients with Bismuth type IV hilar cholangiocarcinoma (HCCA). The purpose of this study was to identify anatomical factors that predict curative-intended resection. Methods Thirty-three of 159 patients with Bismuth type IV HCCA underwent major hepato-biliary resection with curative intent (CIR) between 2000 and 2010. Disease extent and anatomical variations were analyzed as factors enabling CIR. Results CIR ratio with hilar trifurcation bile duct variation (13/16) was significantly higher than that with other bile duct variation types (18/25). Hilum to left second bile duct confluence and tumor infiltration over left second bile duct confluence lengths in right-sided CIR were significantly shorter than those lengths in left-sided CIR (10.8 ± 4.9 and 2.7 ± 0.8 mm vs. 16.5 ± 8.4 and 7.0 ± 5.3 mm, respectively). Left-sided CIR patients had a marginally higher proportion of tumors invading ≤5 mm over the right second confluence than that in right-sided CIR patients (13/17 vs. 6/16; P = 0.061). The 3-year survival rate after CIR (28%) was significantly higher than after non-CIR (6.1%). Conclusion We recommend the criteria of CIR as bile duct variation type, length of hilum to contralateral second bile duct confluence, and extent of tumor infiltration over the second confluence for Bismuth type IV HCCA.

Abstract
Hilar cholangiocarcinoma (HC) is a rare disease with a poor prognosis which typically presents in the 6(th) decade of life. Of the 3,000 cases seen annually in the United States, less than one half of these tumors are resectable. A variety of risk factors have been associated with HC, most notably primary sclerosing cholangitis (PSC), biliary stone disease and parasitic liver disease. Patients typically present with abdominal pain, pruritis, weight loss, and jaundice. Computed topography (CT), magnetic resonance imaging (MRI), and ultrasound (US) are used to characterize biliary lesions. Endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiography (PTC) assess local ductal extent of the tumor while allowing for therapeutic biliary drainage. MRCP has demonstrated similar efficacies to PTC and ERCP in identifying anatomic extension of tumors with less complications. Treatment consists of surgery, radiation, chemotherapy and photodynamic therapy. Biliary drainage of the future liver remnant should be performed to decrease bilirubin levels thereby facilitating future liver hypertrophy. Standard therapy consists of surgical margin-negative (R0) resection with extrahepatic bile duct resection, hepatectomy and en bloc lymphadenectomy. Local resection should not be undertaken. Lymph node invasion, tumor grade and negative margins are important prognostic indicators. In instances where curative resection is not possible, liver transplantation has demonstrated acceptable outcomes in highly selected patients. Despite the limited data, chemotherapy is indicated for patients with unresectable tumors and adequate functional status. Five-year survival after surgical resection of HC ranges from 10% to 40% however, recurrence can be as high as 50-70% even after R0 resection. Due to the complexity of this disease, a multi-disciplinary approach with multimodal treatment is recommended for this complex disease.

Abstract
This article presents general principles and recent advancements in the clinical application of augmented reality-based navigation surgery (AR based NS) for abdominal procedures and includes a description of our clinical trial and subsequent outcomes. Moreover, current problems and future aspects are discussed. The development of AR-based NS in the abdomen is delayed compared with another field because of the problem of intraoperative organ deformations or the existence of established modalities. Although there are a few reports on the clinical use of AR-based NS for digestive surgery, sophisticated technologies in urology have often been reported. However, the rapid widespread use of video- or robot assisted surgeries requires this technology. We have worked to develop a system of AR-based NS for hepatobiliary and pancreatic surgery. Then we developed a short rigid scope that enables surgeons to obtain 3D view. We recently focused on pancreatic surgery, because intraoperative organ shifting is minimal. The position of each organ in overlaid image almost corresponded with that of the actual organ with about 5 mm of mean registration errors. Intraoperative information generated from this system provided us with useful navigation. However, AR-based NS has several problems to overcome such as organ deformity, evaluation of utility, portability or cost.

Abstract
Multiplanar reconstruction (MPR) images are used for assessing horizontal and vertical extent of hilar cholangiocarcinoma, while peroral cholangioscopy (POCS) is used for diagnosing ductal spread and mapping biopsy. We fused conventional 3-dimensional computed tomography (3DCT) with MPR images and POCS findings for preoperative assessment of cholangiocarcinoma. The extent of cancer was assessed using MPR images, which were plotted and fused onto 3DCT cholangiography. In addition, the results of mapping biopsy performed under POCS were marked on virtual endoscopic imaging and transferred onto a 3DCT image. Once an angiographic CT image was fused, a multi-3DCT image was created. The incision line was determined based on these images. Multi-3DCT images were created for 13 patients with hilar cholangiocarcinoma. Of 10 patients who underwent POCS, superficial spread was observed in two. Resection was performed in 12 patients. In two cases, the cut end of the intrahepatic bile duct was positive, resulting in 83.3% diagnostic accuracy for horizontal spread. In all patients, the estimated number of bile ducts was the same as the number of the actual resections. R0 resection was achieved in 10 patients (83.3%). Multi-3DCT imaging proved useful in diagnosing longitudinal ductal spread of hilar cholangiocarcinoma.

Abstract
Cholangiocarcinoma (CCA) is the second most common primary hepatic malignancy worldwide. The incidence of intrahepatic CCA is increasing, whereas that of extrahepatic CCA is decreasing. This review looks at the new advances that have been made in the management of CCA, based on a PubMed and Science Citation Index search of results from randomized controlled trials, reviews, and cohort, prospective and retrospective studies. Aggressive interventional approaches and new histopathological techniques have been developed to make a histological diagnosis in patients with high risk factors or suspected CCA. Resectability of the tumour can now be assessed using multiple radiological imaging studies; the main prognostic factor after surgery is a histologically negative resection margin. Biliary drainage and/or portal vein embolization may be performed before extended radical resection, or liver transplantation may be undertaken in combination with neoadjuvant chemotherapy or chemoradiotherapy. Though many advances have been made in the management of CCA, the standard modality of treatment has not yet been established. This review focuses on the clinical options for different stages of CCA.
