Abstract
Background Hepatectomy with vascular resection (VR) for perihilar cholangiocarcinoma (PHCC) is a challenging procedure. However, only a few reports on this procedure have been published and its clinical significance has not been fully evaluated. Methods Patients undergoing surgical resection for PHCC from 2002–2017 were studied. The surgical outcomes of VR and non-VR groups were compared. Results Some 238 patients were included. VR was performed in 85 patients. The resected vessels were hepatic artery alone (31 patients), portal vein alone (37 patients) or both (17 patients). The morbidity rates were almost the same in the VR (49.4 per cent) and non-VR (43.8 per cent) groups (P = 0.404). The mortality rates of VR (3.5 per cent) and non-VR (3.3 per cent) were also comparable (P > 0.999). The median survival time (MST) was 45 months in the non-VR group and 36 months in VR group (P = 0.124). Among patients in whom tumour involvement was suspected on preoperative imaging and whose carbohydrate antigen 19-9 (CA19-9) value was 37 U/ml or less, MST in the VR group was significantly longer than that in the non-VR group (50 versus 34 months, P = 0.017). In contrast, when the CA19-9 value was greater than 37 U/ml, MST of the VR and non-VR groups was comparable (28 versus 29 months, P = 0.520). Conclusion Hepatectomy with VR for PHCC can be performed in a highly specialized hepatobiliary centre with equivalent short- and long-term outcomes to hepatectomy without VR.

Abstract
BACKGROUND Hepatectomy with extrahepatic bile duct resection is associated with a high risk of posthepatectomy liver failure (PHLF). However, the utility of the remnant liver volume (RLV) in cholangiocarcinoma has not been studied intensively. METHODS Patients who underwent major hepatectomy with extrahepatic bile duct resection between 2002 and 2018 were reviewed. The RLV was divided by body surface area (BSA) to normalize individual physical differences. Risk factors for clinically relevant PHLF were evaluated with special reference to the RLV/BSA. RESULTS A total of 289 patients were included. The optimal cut-off value for RLV/BSA was determined to be 300 ml/m2. Thirty-two patients (11.1 per cent) developed PHLF. PHLF was more frequent in patients with an RLV/BSA below 300 ml/m2 than in those with a value of 300 ml/m2 or greater: 19 of 87 (22 per cent) versus 13 of 202 (6.4 per cent) (P < 0.001). In multivariable analysis, RLV/BSA below 300 ml/m2 (P = 0.013), future liver remnant plasma clearance rate of indocyanine green less than 0.075 (P = 0.031), and serum albumin level below 3.5 g/dl (P = 0.015) were identified as independent risk factors for PHLF. Based on these risk factors, patients were classified into three subgroups with low (no factors), moderate (1-2 factors), and high (3 factors) risk of PHLF, with PHLF rates of 1.8, 14.8 and 63 per cent respectively (P < 0.001). CONCLUSION An RLV/BSA of 300 ml/m2 is a simple predictor of PHLF in patients undergoing hepatectomy with extrahepatic bile duct resection.

Abstract
BACKGROUND The length of tumour-vein contact between the portal-superior mesenteric vein (PV/SMV) and pancreatic head cancer, and its relationship to prognosis in patients undergoing pancreatic surgery, remains controversial. METHODS Patients diagnosed with pancreatic head cancer who were eligible for pancreatoduodenectomy between October 2002 and December 2016 were analysed. The PV/SMV contact was assessed retrospectively on CT. Using the minimum P value approach based on overall survival after surgery, the optimal cut-off value for tumour-vein contact length was identified. RESULTS Among 491 patients included, 462 underwent pancreatoduodenectomy for pancreatic head cancer. PV/SMV contact with the tumour was detected on preoperative CT in 248 patients (53·7 per cent). Overall survival of patients with PV/SMV contact exceeding 20 mm was significantly worse than that of patients with a contact length of 20 mm or less (median survival time (MST) 23·3 versus 39·3 months; P = 0·012). Multivariable analysis identified PV/SMV contact longer than 20 mm as an independent predictor of poor survival, whereas PV/SMV contact greater than 180° was not a predictive factor. Among patients with a PV/SMV contact length exceeding 20 mm on pretreatment CT, those receiving neoadjuvant therapy had significantly better overall survival than patients who had upfront surgery (MST not reached versus 21·6 months; P = 0·002). CONCLUSION The length of PV/SMV contact predicts survival, and may be used to suggest a role for neoadjuvant therapy to improve prognosis.

Abstract
BACKGROUND AND AIM Intrahepatic metastasis (IM) of hepatocellular carcinoma (HCC) occurs via vascular invasion; the tumor diameter that affects the risk of micro intra-hepatic metastasis (MIM) should be larger than that which affects the risk of micro vessel invasion (MVI). The aim of the present study was to determine the optimum tumor diameter cut-off value for predicting the presence of MIM in HCC patients without treatment history and HCC patients with a treatment history and to compare these diameters between cases of MVI and MIM. METHODS This retrospective study included 621 patients without macroscopic vessel invasion or intrahepatic metastasis on preoperative imaging who underwent hepatectomy. The cut-off tumor diameter for predicting the presence of MIM was determined by a receiver operating characteristic curves analysis. RESULTS The optimum cut-off value for predicting the presence of MIM in HCC patients without treatment history was 43 mm. In contrast, the optimum cut-off value for predicting the presence of MIM in HCC patients with a treatment history was 20 mm. Among 46 HCC patients with MIM without treatment history, there were 20 patients with MIM without MVI who were considered to have potential multi-centric (MC) tumors rather than IM. The cumulative overall survival rates in patients with MIM without MVI (potential MC) was significantly better than that in patients with both MIM and MVI (P = 0.022). CONCLUSIONS The tumor diameter cut-off value for predicting MIM differed between HCC patients without treatment history and with a treatment history and slightly smaller than those for predicting MVI beyond our expectation.

Abstract
BACKGROUND Although some retrospective studies have suggested the value of adjuvant therapy, no recommended standard exists in bile duct cancer. The aim of this study was to test the hypothesis that adjuvant gemcitabine chemotherapy would improve survival probability in resected bile duct cancer. METHODS This was a randomized phase III trial. Patients with resected bile duct cancer were assigned randomly to gemcitabine and observation groups, which were balanced with respect to lymph node status, residual tumour status and tumour location. Gemcitabine was given intravenously at a dose of 1000 mg/m2 , administered on days 1, 8 and 15 every 4 weeks for six cycles. The primary endpoint was overall survival, and secondary endpoints were relapse-free survival, subgroup analysis and toxicity. RESULTS Some 225 patients were included (117 gemcitabine, 108 observation). Baseline characteristics were well balanced between the gemcitabine and observation groups. There were no significant differences in overall survival (median 62·3 versus 63·8 months respectively; hazard ratio 1·01, 95 per cent c.i. 0·70 to 1·45; P = 0·964) and relapse-free survival (median 36·0 versus 39·9 months; hazard ratio 0·93, 0·66 to 1·32; P = 0·693). There were no survival differences between the two groups in subsets stratified by lymph node status and margin status. Although haematological toxicity occurred frequently in the gemcitabine group, most toxicities were transient, and grade 3/4 non-haematological toxicity was rare. CONCLUSION The survival probability in patients with resected bile duct cancer was not significantly different between the gemcitabine adjuvant chemotherapy group and the observation group.

Abstract
Background Non‐anatomical liver resection (NAR) and radiofrequency ablation (RFA) are treatment options for early‐stage hepatocellular carcinoma (HCC). The aim was to compare the outcomes of NAR and RFA for HCC in patients with three or fewer tumour nodules, each measuring not more than 3 cm in maximum diameter. Methods Eligible patients undergoing NAR or RFA with curative intent between September 2002 and December 2014 were identified. A propensity score‐matching analysis was performed to reduce bias, and outcomes in these patients were analysed. Results From a total of 199 patients, 1:1 propensity score matching identified 70 matched pairs. Patients having NAR had a longer hospital stay (median 10 days versus 4 days for those who had RFA; P < 0·001) and a higher morbidity rate (24 versus 10 per cent respectively; P = 0·042). Patients who had NAR had slightly better recurrence‐free survival but this failed to reach statistical significance in univariable analysis (P = 0·064). There was no significant difference in overall survival between the two groups (P = 0·475). RFA was identified as an independent risk factor for recurrence‐free survival (hazard ratio (HR) 1·57; P = 0·041) in multivariable analysis. Local recurrence was significantly more common in patients receiving RFA (23 versus 1 per cent; P < 0·001). Conclusion RFA was an independent risk factor for shorter recurrence‐free survival, with a significantly higher local recurrence rate than NAR. Despite these differences, overall survival was not affected.

Abstract
BACKGROUND Some reports have stated that pancreatoduodenectomy for elderly patients have comparable morbidity and mortality to that of young patients. However, the long-term outcomes of these patients have not been fully evaluated, especially for pancreatic head cancer. METHODS A total of 227 patients who underwent pancreatoduodenectomy for pancreatic head cancer between 2007 and 2014 were included. They were stratified according to age: young (<70 years), elderly (70 to <80 years), and very elderly (≥80 years). The short- and long-term outcomes were evaluated. RESULTS There were no significant differences in terms of morbidity among the three groups. The median disease-free survival times were 15 months in the young, 11 months in the elderly, and 7 months in the very elderly. The disease-free survival of the young patients was significantly better than that in both the elderly and the very elderly (p = 0.012 and p = 0.016). The median overall survival times were 30 months in the young, 20 months in the elderly, and 14 months in the very elderly. The overall survival of the young patients was significantly better than that in both the elderly and the very elderly (p = 0.007 and p < 0.001). The difference was marginal between the elderly and the very elderly (p = 0.053). Multivariate analysis revealed that lymph node metastasis (p < 0.001), age ≥80 years (p = 0.013), lack of adjuvant chemotherapy (p = 0.003), blood transfusion (p = 0.015), and CA 19-9 ≥300 U/ml (p = 0.040) were significant prognostic factors. CONCLUSIONS Patient age influenced the survival after pancreatoduodenectomy for pancreatic cancer.

Abstract
Abstract
Background
The preoperative serum neutrophil to lymphocyte ratio (NLR) has been associated with survival in patients with hepatocellular carcinoma (HCC). However, it is still unclear what the NLR reflects precisely. This study aimed to elucidate the relationship between the NLR and TNM stage, and the role of NLR as a prognostic factor after liver resection for HCC.
Methods
This retrospective study enrolled patients who underwent liver resection as initial treatment for HCC. The best cut-off value of serum NLR was determined, and overall survival was compared among patients grouped according to TNM stage (I, II and III).
Results
The best cut-off value for NLR was 2·8. A high preoperative NLR was more frequently associated with poor overall survival than a low preoperative NLR after resection for TNM stage I tumours (5-year survival 45·0 versus 76·4 per cent, P < 0·001), but not stage II (P = 0·283) or stage III (P = 0·155) tumours. Among patients with TNM stage I disease, the proportion of patients with extrahepatic recurrence was greater in the group with a high preoperative NLR than in the low-NLR group (P = 0·006). In multivariable analysis, preoperative NLR was the strongest independent prognostic risk factor for overall survival in TNM stage I (hazard ratio 2·69, 95 per cent c.i. 1·57 to 4·59; P < 0·001).
Conclusion
Preoperative NLR was an important prognostic factor for TNM stage I HCC after liver resection with curative intent. These results suggest that the NLR may reflect the malignant potential of HCC.

Abstract
Abstract
Background
Several risk factors for complications after pancreaticoduodenectomy have been reported. However, the impact of intraoperative bacterial contamination on surgical outcome after pancreaticoduodenectomy has not been examined in depth.
Methods
This retrospective study included patients who underwent pancreaticoduodenectomy and peritoneal lavage using 7000 ml saline between July 2012 and May 2014. The lavage fluid was subjected to bacterial culture examination. The influence of a positive bacterial culture on surgical-site infection (SSI) and postoperative course was evaluated. Risk factors for positive bacterial cultures were also evaluated.
Results
Forty-six (21·1 per cent) of 218 enrolled patients had a positive bacterial culture of the lavage fluid. Incisional SSI developed in 26 (57 per cent) of these 46 patients and in 13 (7·6 per cent) of 172 patients with a negative lavage culture (P < 0·001). Organ/space SSI developed in 32 patients with a positive lavage culture (70 per cent) and in 43 of those with a negative culture (25·0 per cent) (P < 0·001). Grade B/C pancreatic fistula was observed in 22 (48 per cent) and 48 (27·9 per cent) respectively of patients with positive and negative lavage cultures (P = 0·010). Postoperative hospital stay was longer in patients with a positive lavage culture (28 days versus 21 days in patients with a negative culture; P = 0·028). Multivariable analysis revealed that internal biliary drainage, combined colectomy and a longer duration of surgery were significant risk factors for positive bacterial culture of the lavage fluid.
Conclusion
Intraoperative bacterial contamination has an adverse impact on the development of SSI and grade B/C pancreatic fistula following pancreaticoduodenectomy.

Abstract
BACKGROUND Preoperative portal vein embolization (PVE) is performed to enhance the future remnant liver function (FRLF) and volume (FRLV). However, the volume of the nonembolized liver does not increase enough in some patients, which results in an insufficient FRLF. The aim of this study was to evaluate the predictors of insufficient FRLF after PVE for extended hepatectomy. METHODS This retrospective study included 172 patients (107 patients with cholangiocarcinoma, 40 patients with metastatic liver cancer and 25 patients with hepatocellular carcinoma) who underwent PVE before extended hepatectomy. The total liver function was evaluated by measuring the indocyanine green plasma clearance rate (KICG). Computed tomography volumetry was conducted to evaluate the total liver volume and FRLV. The KICG of the future remnant liver (remK) was calculated using the following formula: KICG × FRLV/total liver volume. The safety margin for hepatectomy was set at remK after PVE (post-PVE remK) ≥ 0.05. RESULTS One hundred and twenty-three patients with a post-PVE remK level of >0.05 underwent hepatectomy without postoperative liver failure [sufficient liver regeneration (SLR) group], and 9 patients with a post-PVE remK level of <0.05 did not due to insufficient FRLF [insufficient liver regeneration (ILR) group]. In the SLR group, the KICG values did not change after PVE (median, 0.144-0.146, p = 0.523); however, the %FRLV and remK increased significantly (35.0-44.3%, p < 0.001 and 0.0488-0.0610, p < 0001, respectively). In contrast, in the ILR group, the KICG values decreased significantly (0.128-0.108, p = 0.021) and the %FRLV increased marginally (27.4-32.6%, p = 0.051). As a result, the remK did not increase significantly (0.0351-0.0365, p = 0.213). A receiver operating characteristic curve demonstrated an remK value of 0.04 obtained before PVE (pre-PVE remK) to be the optimal cutoff point for defective liver regeneration. The univariate and multivariate analyses revealed that a pre-PVE remK value of <0.04 was a factor for ILR. It was also correlated with postoperative liver failure in the analysis of the patients who underwent hepatectomy. CONCLUSIONS The patients in the ILR group did not achieve SLR after PVE due to a significant decrease in the KICG and an insufficient increase in %FRLV. A pre-PVE remK value of <0.04 is a useful predictor of insufficient regeneration of the nonembolized liver, even after PVE.

Abstract
84 Background: In recent TNM classification, positive peritoneal cytology (CY1) is regarded as M1 disease and classified into stage IV. However, the prognosis of the CY1 patients underwent R1 surgery (microscopic residual tumor) is considered to be relatively better than those underwent R2 surgery (macroscopic residual tumor). Adjuvant chemotherapy with S-1 had demonstrated significant survival benefit in stage II and III gastric cancer in Japan. However, the efficacy of adjuvant S-1 in patients with relatively more advanced stage had not been investigated. Therefore, we investigated the efficacy of adjuvant chemotherapy with S-1 in CY1 patients underwent R1 surgery. Methods: Among the 2,202 patients with gastric cancer treated at our department between September 2002 and July 2009, a total of 105 patients with CY1 and underwent R1 surgery were included in this study. Clinocopathological features and survival were retrospectively analyzed using prospectively registered data base system. Results: There were 64 male and 41 female patients. The median age was 61 years old. Eighty-five patients had T4a or T4b tumor and 96 patients had lymph node metastasis. Seventy-eight patients had undifferentiated type of tumor. In 83 patients, adjuvant chemotherapy with S-1 had been performed. In the uni-variate analysis, only the extent of lymph node dissection (D2) and the adjuvant chemotherapy with S-1 demonstrated significant survival benefit. In multi-variable analysis using Cox proportional hazarded model, N-factor, extent of lymph node dissection (D2 vs D1), and adjuvant chemotherapy with S-1 were selected as independent prognostic factors. The median survival time and 5-year survival rate in patients underwent R1 resection with D2 lymphadenectomy and adjuvant S-1 treatment were 42 months and 46%, respectively. Conclusions: In patients with CY1 and underwent R1 surgery, adjuvant chemotherapy with S-1 demonstrated significant survival benefit. In patients with positive peritoneal cytology without other non-curative factors, D2 lymph node dissection and adjuvant chemotherapy using S-1 is recommended. No significant financial relationships to disclose.

Abstract
24 Background: Duodenal invasion (DI) has been considered as a poor prognostic factor of gastric cancer patients. Not all the patients would be able to undergo curative operation. Neoadjuvant chemotherapy (NAC) may improve the rate of curative operation of these patients. In this study, we investigated whether the length of duodenal invasion preoperative diagnosis can be one of factor to decide indication of NAC. Methods: A total of 118 gastric cancer patients with clinically evident DI, who underwent laparotomy at our center, were enrolled in this study. 42 patients with DI length 20 mm or longer were categorized into long invasion group (LI), 76 patients with DI length shorter than 20 mm were categorized into short invasion group (SI). Clinicopathologic features, rate of direct invasion and lymph nodes involvement, R0 resection, and survival rate were compared between two groups. Results: Resection rate was significantly different between two groups: SI group (85.5%; 65/76), LI group (69.0%; 29/42). Direct invasion to adjacent organs was significantly more frequently observed in LI group (21%; 6/29) than SI group (4 %; 3/65, p = 0.02). In LI group, pancreas invasion was observed in all patients except for one patient. Multivariate analysis to predict the adjacent organ invasion revealed that CT diagnosis (p = 0.005) and invasion length (p = 0.01) were selected as risk factors of direct invasion to adjacent organs. There was no significant difference of nodal involvement between LI group (83%; 24/29) and SI group (83%; 54/65 p = 0.99). The 5-year survival rate was 19% in LI group and 43% in SI group (p = 0.23). The number of patients who underwent R0 resection was more frequently in SI group (75.4%; 49/65) than SI group (69.1%; 16/29). The factors of R1 or R2 resection were metastasis of peritoneum or direct invasion to adjacent organs. Conclusions: In patients with long duodenal invasion, direct invasion to the pancreas was more frequently observed, and resulted in low curative resection rate and poor survival. Preoperative chemotherapy may improve the curative resection rate and survival in these patients. Prospective study is warranted to evaluate the efficacy of NAC for these patients. No significant financial relationships to disclose.

Abstract
4622 Background: To evaluate the benefits of adjuvant intra-operative radiation therapy after curative resection in advanced pancreatic cancer (APC) patients, a multi-center phase III trial was conducted by 11 participating institutions in Japan. Methods: Eligibility included pts with potentially resectable APC (duct cell origin) by image diagnosis. Patients were randomized in a 1:1 ratio to adjuvant IORT or surgery alone less than a week before surgery. Stratification factors were tumor size (TS1/TS2,3,4), location (head/body and tail), and institution. Patients who were assigned to adjuvant IORT arm received IORT after curative resection before reconstruction. IORT consisted of 25Gy with electron beam energies of more than 6MeV and was delivered by the round shaped acrylic cylinder of 6–8cm diameter. The radiation field included the tumor bed and in most cases included the celiac axis, superior mesenteric artery, and the portal vein. The primary endpoint was overall survival. The secondary endpoint was local control rate at 2 years after surgery. Assuming 65 eligible pts in each arm, the study had 0,8 power to detect 20% difference in 2-year survival rate. Results: Between 05/2002 to 12/2006 198 pts were randomized and 153 pts underwent curative resection with assigned treatment. Among the 153 pts with curative resection, seven pts revealed ineligible by the histological examination. Finally full analysis sets were 144 pts. Seventy three pts were in the IORT arm and 71 pts in the surgery alone arm. There was only one hospital death in the IORT arm. Cause of the death was intraabdominal arterial bleeding due to pancreatic fistula. Conclusions: We now are collecting the final follow up data. The final analyses will be presented at the meeting. No significant financial relationships to disclose.

Abstract
Abstract
Background
The purpose of this study was to clarify the efficacy of, and define the indications for, extensive surgery for gallbladder carcinoma.
Methods
Between 1979 and 1994, 116 patients with gallbladder carcinoma underwent operation. Radical resection was performed in 80 patients.
Results
In 68 patients with stage III or IV disease, extensive resection including extended right hepatectomy (n = 40), pancreaticoduodenectomy (n = 23) and/or portal vein resection (n = 23) was employed to achieve complete tumour excision. The hospital mortality rate was 18 per cent. The postoperative 3- and 5-year survival rates were 44 and 33 per cent respectively in the patients with stage III disease (n = 9), and 24 and 17 per cent respectively in patients with stage IV (M0) disease (n = 29). In contrast, the postoperative survival rate for the 30 patients with stage IV (M1) disease (7 per cent at 3 years and 3 per cent at 5 years) was worse than that for patients with stage III and stage IV (M0) disease (P = 0·009 and P = 0·062 respectively).
Conclusion
Radical resection should be undertaken for stage III and stage IV (M0) gallbladder cancer. Although portal vein resection and/or pancreaticoduodenectomy did not contribute to long-term survival, better survival was obtained than that for the unresected patients.

Abstract
BACKGROUND The clinical significance of perineural invasion of gallbladder carcinoma remains unclear. The aim of this study was to elucidate the incidence and mode of perineural invasion of gallbladder carcinoma and clarify its prognostic significance. METHODS A clinicopathological study was conducted on 68 patients who underwent attempted curative resection for gallbladder carcinoma. According to the pathological tumour node metastasis (pTNM) classification of the Union Internacional Contra la Cancrum, there were five (7 per cent), nine (13 per cent), 20 (29 per cent) and 34 (50 per cent) patients with pT1, pT2, pT3 and pT4 disease respectively. Twenty patients (29 per cent) had pM1 disease, including involved para-aortic nodes, liver metastases and localized dissemination. RESULTS The overall incidence of perineural invasion was 71 per cent (48 of 68 patients). Forty-four (96 per cent) of 46 patients with extrahepatic bile duct invasion had perineural invasion. Although several histological factors were associated with perineural invasion, multivariate analysis demonstrated that extrahepatic bile duct invasion was the only significant factor correlated with perineural invasion (odds ratio 99.0, P < 0.001). The perineural invasion index, defined as the ratio of the number of involved nerves to the total number of nerves examined, was significantly higher at the centre than in the proximal and distal parts of the tumour in the 46 patients with extrahepatic bile duct invasion (P < 0.001). The 5-year survival rate for patients with perineural invasion was significantly lower than that for patients with no invasion (7 versus 72 per cent; P < 0.001). Cox proportional hazard analysis identified perineural invasion (relative risk (RR) 5.3, P < 0.001) and lymph node metastasis (RR 2.5, P = 0.008) as significant independent prognostic factors. CONCLUSION Perineural invasion is common in advanced gallbladder carcinoma and has a significant negative impact on patient survival.

Abstract
PURPOSE To describe 5-year survivors after radical surgery for stage IV gallbladder cancer and to determine the characteristics leading to potential long-term survival. METHODS Of 59 patients undergoing radical resection for stage IV disease between 1979 and 1994, 6 patients who have survived for more than 5 years were followed up. RESULTS Three patients had developed obstructive jaundice due to involvement of the hepatic hilum, but the other three had not. The jaundiced patients had remarkable tumor spread over the bile duct and right hepatic artery within the hepatoduodenal ligament. However, the proper and left hepatic arteries and the portal trunk and its left branch were free from tumor involvement. The nonjaundiced patients had N1 or N2 lymph node metastasis. However, none underwent bile duct resection or pancreatoduodenectomy to establish radical lymphadenectomy. CONCLUSIONS Selected patients with stage IV gallbladder cancer may be candidates for 5-year survival when the primary tumor is fairly localized even if it forms a large mass and involves neighboring organs including the hepatic duct, lymph node metastasis is limited to N1 and N2 except for the celiac and superior mesenteric nodes and is less infiltrative, and distant metastasis including that in the paraaortic area is absent.

Abstract
We retrospectively reviewed postoperative complications in 105 patients with hilar cholangiocarcinoma who underwent hepatectomy at Nagoya University Hospital from January 1990 through March 1999. Of the 105 subjects, 97 (92.4%) underwent resection of two or more Healey's segments of the liver. Combined portal vein resection was performed in 33 (31.4%) patients and pancreatoduodenectomy in 10 (9.5%). Twenty (19.0%) patients had no postoperative complications, another 39 (37.1%) patients had minor complication(s) only, and the remaining 46 (43.8%) developed major complication(s). The morbidity rate reached as high as 81.0%. Major complications required relaparotomy in 11 (10.5%) patients. Of the 46 patients with major complication(s) 36 recovered; the remaining 10 patients died of liver failure with other organ failure(s) or of intraabdominal bleeding 12, 14, 18, 21, 57, 75, 75, 87, 93, or 134 days after surgery. Thus the 30-day mortality was 3.8% and the overall mortality 9.5%. Pleural effusion was the most frequent complication found in 66 (62.9%) patients, followed by wound sepsis in 39 (37.1%), and then liver failure in 29 (27.6%). Liver failure developed in 16.7% of 48 patients with less than 50% liver resection and in 36.8% of 57 patients with 50% or more resection (P < 0.05). Other organ failures, including renal, respiratory, gastrointestinal, and hematologic failures, developed as a sign of multiple organ failure following liver failure in most patients or preceding liver failure in a few patients. None of the six patients with four or more organ failures survived. Hepatectomy for hilar cholangiocarcinoma is risky owing to impaired hepatic functional reserve in jaundiced patients and the technical difficulty associated with hepatobiliary resection. Our goal is to reduce mortality to less than 5% while keeping a high resectability rate (above 80%).

Abstract
BACKGROUND The aim of this study was to evaluate serial changes in liver volume after major hepatectomy for biliary cancer and to elucidate clinical factors influencing liver regeneration. METHODS Serial changes in liver volume were determined, using computed tomography, in 81 patients with biliary cancer who underwent right hepatic lobectomy or more extensive liver resection with or without portal vein resection and/or pancreatoduodenectomy. Possible factors influencing liver regeneration were evaluated by univariate and multivariate analyses. RESULTS The remnant mean(s.d.) liver volume was 41(8) per cent straight after hepatectomy. This increased rapidly to 59(9) per cent within 2 weeks, then increased more slowly, finally reaching a plateau at 74(12) per cent about 1 year after hepatectomy. The regeneration rate within the first 2 weeks was 16(8) cm3/day and was not related to the extent of posthepatectomy liver dysfunction. On multivariate analysis, the extent of liver resection (P < 0.001), body surface area (P = 0.02), combined portal vein resection (P = 0.024) and preoperative portal vein embolization (P = 0.047) were significantly associated with the liver regeneration rate within the first 2 weeks. In addition, body surface area (P < 0.001) and liver function expressed as plasma clearance rate of indocyanine green (P = 0.01) were significant determinants of final liver volume 1 year after hepatectomy. CONCLUSION The liver regenerates rapidly in the first 2 weeks after major hepatectomy for biliary cancer. This early regeneration is influenced by four clinical factors. Thereafter, liver regeneration progresses slowly and stops when the liver is three-quarters of its original volume, approximately 6 months to 1 year after hepatectomy.

Abstract
BACKGROUND The aim of this study was to clarify clinicopathologic characteristics of, and to evaluate an aggressive treatment strategy for, hepatocellular carcinoma with biliary tumor thrombi. METHODS From 1980 to 1999, a total of 132 patients underwent hepatectomy for hepatocellular carcinoma. Of these, 17 patients had macroscopic biliary tumor thrombi and were retrospectively analyzed. RESULTS The operative procedures included right hepatic trisegmentectomy (n = 1), right or left hepatic lobectomy (n = 11), and segmentectomy or subsegmentectomy (n = 5). In 13 patients, tumor thrombi extended beyond the hepatic confluence and was treated by thrombectomy through a choledochotomy in 8 patients and extrahepatic bile duct resection and reconstruction in 5 patients. The 3- and 5-year survival rates were 47% and 28%, respectively, with a median survival time of 2.3 years. These survival rates were similar to those achieved in 115 patients without biliary tumor thrombi. In a multivariate analysis, expansive growth type and solitary tumors were independent prognostic variables for favorable outcome after operation, whereas biliary tumor thrombi was not a significant prognostic factor. CONCLUSIONS Surgery after appropriate preoperative management of hepatocellular carcinoma with biliary tumor thrombi yields results similar to those of patients without biliary involvement. Hepatectomy with thrombectomy through a choledochotomy appears to be as effective as a resection procedure.

Abstract
Intrapancreatic bile duct metastasis from rectal carcinoma is rare. A 48-year-old man underwent extended left hepatic lobectomy and caudate lobectomy with extrahepatic bile duct resection for liver metastasis from a rectal carcinoma presenting with intrabiliary growth. A second recurrent tumor was successfully resected by pancreatoduodenectomy without injury to the jejunal loop for biliary reconstruction. Preservation of the previous bilio-enteric anastomosis was critical. Placing the jejunal limb of the hepaticojejunostomy through the retrogastric route was superior to placement through the common retrocolic and anteduodenal route, because the mesentery of the Roux-en Y jejunal limb did not obscure the pancreatic head. Histologic examination revealed a recurrent tumor growing into the remnant intrapancreatic bile duct. This suggested two possibilities: spontaneous shedding of cancer cells from the proximal metastasis, and implantation as a complication of percutaneous transhepatic biliary drainage. In both these circumstances, the metastatic lesion is not systemic, but is a local disease. An aggressive surgical approach for localized recurrence of this type may improve survival.

Abstract
During a major hepatectomy, inadvertent ligation of the major segmental bile-duct branch of the liver remnant is a serious complication. We experienced this serious complication of inadvertent ligation of the bile-duct branch, which should be anastomosed to the jejunal loop, during a left hepatic trisegmentectomy with total caudate lobectomy for a hilar cholangiocarcinoma. A percutaneous transhepatic bilioenteric connection was then created, modifying an endoscopic ureteroneocystostomy technique, between the ligated segmental bile duct and the jejunal loop. In this procedure, we used two cholangioscopes; one was introduced through the percutaneous transhepatic drainage route, the other was introduced through an enterostomy which was made during the surgery for postoperative enteral feeding; we also used a transjugular intrahepatic portosystemic shunt (TIPS) kit under fluoroscopic guidance. We present here our technique of percutaneous transhepatic bilioenterostomy.

Abstract
We report two different types of portal vein obstruction after liver resection: portal vein thrombosis due to steal phenomenon via a splenorenal shunt, and kinking of the skeletonized left portal vein after right hepatic lobectomy with caudate lobectomy. The two cases of portal vein obstruction were asymptomatic without any suggestive laboratory findings. Only routine Doppler ultrasonography detected portal vein obstruction which was successfully treated by emergency operation.

Abstract
OBJECTIVE To assess the status of the regional and paraaortic lymph nodes in hilar cholangiocarcinoma and to clarify the efficacy of systematic extended lymphadenectomy. SUMMARY BACKGROUND DATA There have been no studies in which regional and paraaortic lymphadenectomies for hilar cholangiocarcinoma have been routinely performed. Therefore, the metastasis rates to the regional and paraaortic nodes, the mode of lymphatic spread, and the effect of extended lymph node dissection on survival remain unknown. METHODS This study involved 110 patients who underwent surgical resection for hilar cholangiocarcinoma with lymph node dissection including both the regional and paraaortic nodes. A total of 2,652 nodes retrieved from the surgical specimens were examined microscopically. RESULTS Of the 110 patients, 52 (47.3%) had no involved nodes, 39 (35.5%) had regional lymph node metastases, and 19 (17.3%) had regional and paraaortic node metastases. The incidence of positive nodes was significantly higher in the patients with pT3 disease than in those with pT2 disease. The pericholedochal nodes were most commonly involved (42.7%), followed by the periportal nodes (30.9%), the common hepatic nodes (27.3%), and the posterior pancreaticoduodenal nodes (14.5%). The celiac and superior mesenteric nodes were rarely involved. The 3-year and 5-year survival rates were 55.4% and 30.5% for the 52 patients without involved nodes, 31.8% and 14.7% for the 39 patients with regional node metastases, and 12.3% and 12.3% for the 19 patients with paraaortic node metastases, respectively. Of the 19 patients with positive paraaortic nodes, 7 had no macroscopic evidence of paraaortic disease on intraoperative inspection. The survival in this group was significantly better than in the remaining 12 patients. CONCLUSION The paraaortic nodes and the regional nodes are frequently involved in advanced hilar cholangiocarcinoma. Whether extended lymph node dissection provides a survival benefit requires further study. However, the fact that long-term survival is possible despite pN2 or pM1 disease encourages the authors to perform an aggressive surgical procedure with extended lymph node dissection in selected patients with hilar cholangiocarcinoma.

Abstract
BACKGROUND Liver failure accompanied by hyperbilirubinemia after major hepatic resection is profoundly associated with septic complications. Although the immune dysfunction in cholestasis has been intensively investigated, the contribution of increased serum bilirubin to the impaired resistance to bacterial infection remains to be elucidated. Because bilirubin possesses an antioxidant activity, we hypothesized that bilirubin may scavenge reactive oxygen species (ROS) produced by neutrophils and consequently impair neutrophil bacterial killing. To address this, we evaluated the effects of bilirubin on the bactericidal activity of ROS or of neutrophils in vitro. MATERIALS AND METHODS The antioxidant activity of bilirubin was determined using an ROS-sensitive fluorophore, dichlorofluorescin diacetate (DCFH-DA). Bilirubin concentration in the buffer solution was monitored spectorophotometrically after incubation with ROS. The effect of bilirubin on killing of Escherichia coli by ROS or by isolated human neutrophils was determined by counting the viable E. coli after incubation on nutrient agar. RESULTS The bilirubin concentration in the buffer solution was decreased by the addition of hydrogen peroxide, especially in the presence of peroxidase or ferrous iron. DCFH-DA oxidation by ROS or activated neutrophils was inhibited by bilirubin in a dose-dependent manner. The bactericidal activity of ROS or of isolated neutrophils was significantly attenuated by bilirubin. CONCLUSIONS Bilirubin impairs bactericidal activity of neutrophils through scavenging ROS. Increased levels of serum bilirubin may well be responsible for the impaired bacterial clearance in patients with hyperbilirubinemia.

From 1977 to 1997, surgical resection was possible in 142 (80%) of 177 patients with hilar cholangiocarcinoma after relieving jaundice by single or multiple percutaneous transhepatic biliary drainage followed by percutaneous transhepatic cholangioscopy and/or percutaneous trans-hepatic portal vein embolization. Curative resection was possible in 108 (61%) of the 142 patients, and 100 of these patients underwent various types of hepatectomy with caudate lobectomy for a 30-day operative mortality rate of 6% and 9% hospital mortality. Combined portal vein resection was carried out in 43 cases including 41 hepatectomies and 2 bile duct resections. Hepatopancreatoduodenectomy was performed in 16 patients. Cancer recurrence was observed in 58 of the 108 patients undergoing curative resection. The 3-, 5-, and 10-year survival rates for 100 patients undergoing curative hepatectomy and 8 with curative bile duct resection were 43%, 26%, and 19%; and 31%, 16%, and 0%, respectively; those for 40 patients with positive lymph node metastasis, 84 with perineural invasion, and 43 with combined portal vein resection were 27%, 14%, and 7%; 34%, 21%, and 13%; and 18%, 6%, and 0%, respectively. These survival rates are significantly better than those for 35 patients with unresectable cancer. Curative resection after aggressive preoperative management is recommended as a reasonable surgical approach to hilar cholangiocarcinoma.

Abstract
OBJECTIVE To compare the experience and outcome in the management of hilar cholangiocarcinoma at one American and one Japanese medical center. SUMMARY BACKGROUND DATA Controversies surround the issues of extent of resection for hilar cholangiocarcinoma and whether the histopathology of such cancers are similar between patients treated in America and in Japan. METHODS Records were reviewed of 100 patients treated between 1980 and 1995 at the Lahey Clinic in the United States, and of 155 patients treated between 1977 and 1995 at Nagoya University Hospital in Japan. Selected pathologic slides of resected cancers were exchanged between the two institutions and reviewed for diagnostic concordance. RESULTS In the Lahey cohort, there were 25 resections, 53 cases of surgical exploration with biliary bypass or intubation, and 22 cases of percutaneous transhepatic biliary drainage or endoscopic biliary drainage without surgery. In the Nagoya cohort, the respective figures were 122, 10, and 23. The overall 5-year survival rate of all patients treated (surgical and nonsurgical) during the study periods was 7% in the Lahey cohort and 16% in the Nagoya cohort. The overall 10-year survival rates were 0% and 12%, respectively. In patients who underwent resection with negative margins, the 5- and 10-year survival rates were 43% and 0% for the Lahey cohort and 25% and 18% for the Nagoya cohort. The surgical death rate for patients undergoing resection was 4% for Lahey patients and 8% for Nagoya patients. Of the patients who underwent resection, en bloc caudate lobectomy was performed in 8% of the Lahey patients and 89% of the Nagoya patients. Histopathologic examination of resected cancers showed that the Nagoya patients had a higher stage of disease than the Lahey patients. CONCLUSIONS In both Lahey and Nagoya patients, survival was most favorable when resection of hilar cholangiocarcinoma was accomplished with margin-negative resections. Combined bile duct and liver resection with caudate lobectomy contributed to a higher margin-negative resection rate in the Nagoya cohort.

Abstract
Liver resection for hilar cholangiocarcinoma should be designed for individual patients, based on both precise diagnosis of cancer extent and accurate evaluation of hepatic functional reserve. Therefore we have developed various types of hepatic segmentectomy. Combined caudate lobectomy is essential in every patient with separated hepatic confluence. So-called extensive hepatectomy, resection of 50% or more of the hepatic mass, includes right lobectomy and right or left trisegmentectomy. Right lobectomy with caudate lobectomy is indicated when the progression of cancer is predominant in the right anterior and posterior segmental bile ducts. The plane of liver transection is along the Cantlie line, and the left hepatic duct is divided just at the right side of the umbilical portion of the left portal vein. Right trisegmentectomy with caudate lobectomy is performed in carcinoma which involves the right hepatic ducts in continuity with the left medial segmental bile duct. The umbilical portion of the left portal vein is freed from the umbilical plate by dividing the small portal branches arising from the cranial side of the umbilical portion. Then the left lateral segmental bile ducts are exposed and divided at the left side of the umbilical portion of the left portal vein. Left trisegmentectomy with caudate lobectomy is suitable for carcinoma which involves the left intrahepatic bile duct in continuity with the right anterior segmental bile duct. Liver transection is advanced along the right portal fissure. The right posterior segmental bile duct is usually divided distal to the confluence of the inferior and superior branches.

Abstract
BACKGROUND There have been no reports on the routine use of regional and para-aortic lymphadenectomy for gallbladder cancer. The aim of this study was to elucidate nodal status, its prognostic influence and the efficacy of lymphadenectomy. METHODS A retrospective analysis was made of 60 patients who underwent radical resection and routine regional and para-aortic lymphadenectomy. RESULTS Of the 60 patients, 73 per cent had node-positive disease and 38 per cent had positive para-aortic nodes. Postoperative survival was extremely poor in patients with minimal distant metastasis, and similarly in patients with para-aortic disease. The survival of patients with metastasis limited to the regional nodes was significantly better than that of those with distant metastasis (P = 0.029) or para-aortic disease (P = 0.017) and was not significantly different from that of patients with no metastasis (P = 0.82). CONCLUSION Regional and para-aortic lymphadenectomy provides no survival benefit for patients with para-aortic disease, which has an influence on poor prognosis equivalent to that of distant metastasis. It has the potential to bring survival benefit only in selected patients with metastasis limited to the regional nodes. A sampling biopsy of the para-aortic nodes before starting radical surgery is recommended because they are involved more frequently than expected.

Abstract
A 57-year-old woman underwent laparoscopic cholecystectomy (LC) for cholelithiasis. Continuous bile leak was observed beginning on the first postoperative day. Postoperative endoscopic retrograde cholangiography revealed bile leak through the common hepatic duct, and severe stenosis of the hepatic confluence. A total of three percutaneous transhepatic biliary drainage (PTBD) catheters were inserted to treat obstructive jaundice and cholangitis. The patient was referred to our hospital for surgery 118 days after LC. Cholangiography through the PTBD catheters demonstrated a hilar biliary obstruction. Celiac arteriography revealed obstruction of the right hepatic artery, and transarterial portography showed occlusion of the right anterior portal branch. On the basis of the cholangiographic and angiographic findings, we performed a right hepatic lobectomy with hepaticojejunostomy to resolve the bile duct obstruction and address the problem of major vascular occlusion. The patient's postoperative recovery was uneventful and she remains well 25 months after hepatectomy. We discuss a treatment strategy for bile duct injury suspected after LC, involving early investigation of the biliary tree and prompt intervention.

Abstract
BACKGROUND Right portal vein embolization has become popular in preparation for right hepatic lobectomy. However, right trisegment portal vein embolization (R3PE) is not well established. METHODS We performed R3PE in 15 patients with biliary tract carcinoma and 1 patient with primary sclerosing cholangitis. We used 2 types of 5.5 F triple-lumen balloon catheters to embolize portal branches of the right trisegment (the left medial, the right anterior, and the right posterior segments). RESULTS R3PE was successful in all patients without any complications. The calculated volume of the right lobe significantly (P < .01) decreased from 650 +/- 161 cm3 before embolization to 585 +/- 143 cm3 after embolization; the volume of the left lateral segment significantly (P < .0005) increased from 240 +/- 58 cm3 to 361 +/- 66 cm3. The volume of the left medial segment was unchanged. The volume gain of the left lateral segment was larger in patients with R3PE than in those patients (n = 41) with right portal vein embolization (122 +/- 39 cm3 vs 66 +/- 35 cm3; P < .0001). Two of the 16 patients underwent only laparotomy because of peritoneal dissemination, and the remaining 14 patients underwent right hepatic trisegmentectomy with caudate lobectomy. In addition, portal vein resection was also performed in 5 patients, and pancreatoduodenectomy and right hemicolectomy was performed in 3 patients. One patient died of posthepatectomy liver failure 87 days after surgery, a mortality rate of 7.1% (1/14 patients). CONCLUSIONS R3PE is more useful than standard right portal vein embolization in preparation for right hepatic trisegmentectomy and has the potential to increase the safety of this high-risk surgery for patients with biliary tract carcinoma.
