Abstract
BACKGROUND Peritoneal dissemination is the most frequent mode of recurrence in patients with gastric cancer. We tried to identify factors that predict peritoneal recurrence with high sensitivity. STUDY DESIGN Clinical and pathologic data from 587 consecutive patients with gastric cancer were reviewed retrospectively. The stepwise Cox proportional hazards regression model was used to assess the prognostic significance of the magnitude of serosal changes. Multiple stepwise logistic regression analysis was used to determine factors associated with peritoneal recurrence in 375 patients who underwent curative resection. RESULTS The 5-year survival rate of patients with S2 disease (greatest dimension of macroscopic serosal changes >/= 2.5 cm) was 18%, which was worse than S0 (no serosal changes) and S1 disease (macroscopic serosal changes < 2.5 cm)(p < 0.001). Patients with S0 tumors who underwent curative resection had the best 5-year survival rate. Multivariate analyses indicated that the magnitude of serosal changes was an independent prognostic factor for survival both overall and after curative resection. Logistic regression analysis showed that peritoneal recurrence was more than four times as likely with S2 than with S0 or S1 tumors. The sensitivity for predicting peritoneal recurrence was 79%; the sensitivity of cytologic examination was 38%. CONCLUSIONS Magnitude of serosal changes is easy to measure intraoperatively and predicts peritoneal recurrence of gastric cancer with greater sensitivity than conventional peritoneal lavage cytology.

Abstract
BACKGROUND The functional recovery of the remnant liver after an extended hepatectomy is critical for the outcome of the patient. The aim of this prospective study was to examine whether biliary bile acids could be an indicator for postoperative liver function. METHODS Externally drained bile samples were obtained from 51 patients with biliary or periampullary carcinomas before and after surgery. Patients were categorized into 3 groups: group A, 29 hepatectomized patients without liver failure; group B, 7 hepatectomized patients with liver failure (maximum serum bilirubin level, >10 mg/dL); and group C, 15 patients who underwent biliopancreatic resection without hepatectomy, with a good postoperative course. Bile samples were withdrawn 1 day before surgery and on postoperative days 1, 2, 3, 4, 6, and 7. Total bile acids were measured with a 3 alpha-hydroxysteroid dehydrogenase method. RESULTS Before surgery, the concentration of bile acids was higher in groups A and C than in group B, and correlated significantly with the indocyamine green disappearance rate (KICG) values (R(2) = 0.557; P <.0001). After surgery, bile acid concentrations decreased in all 3 groups until postoperative day 2, which was followed by a gradual increase. The concentration recovered to the preoperative level in groups A and C but remained low in group B. Biliary bile acid concentrations on day 2 correlated significantly with remnant liver KICG values (R(2) = 0.257; P =.0019). Among several parameters studied, including KICG, remnant liver KICG, biliary bile acids, and biliary bilirubin, biliary bile acid concentration had the most predictive power for occurrence of postoperative liver failure. CONCLUSION Biliary bile acid concentration could be a simple, real-time, reliable indicator of preoperative and postoperative liver function.

Abstract
BACKGROUND The dorsal subsegmental intrahepatic bile duct in the right anterior superior segment (B8c) sometimes joins the posterior sectorial duct. In such cases it can be misidentified as the right posterior superior segmental duct (B7). However, there are no published studies on the confluent pattern of B8c. MATERIALS AND METHODS We studied B8c in the resected liver of 107 patients (65 with bile duct carcinoma and 42 with gallbladder carcinoma) who had undergone right hepatectomy or more extensive right-sided liver resection. RESULTS B8c was identified in all cases. It joined the right posterior sectorial duct or B7 in 18 cases (16.8%). In 12 cases B8c joined independently the posterior sectorial duct or B7. In 6 cases B8c joined the posterior sectorial duct after making the common duct with the lateral subsegmental duct in the anterior superior or anterior inferior segment (B8b or B5c). CONCLUSIONS B8c does not join the anterior sectorial bile duct in every sixth case.

Abstract
The goal of this study was to determine which projection for percutaneous transhepatic portography best depicts the anatomy of the proximal portal vein. Portograms ( n = 47) obtained in the anteroposterior, right anterior oblique, and right anterior caudal oblique projections were analyzed retrospectively. Lengths of the right portal trunk, the transverse portion of the left portal vein, and the right anterior and posterior portal branches, as well as angles between the right portal trunk and the transverse portion of the left portal vein and between the right anterior and posterior portal branches were measured in the various projections. Differences were evaluated using analysis of variance with Scheffe's method. The transverse portion of the left portal vein and the right anterior and posterior portal branches appeared longer on the right anterior caudal oblique views than on the anteroposterior ( p < 0.0001, < 0.0001, < 0.0001) or right anterior oblique ( p < 0.0001, = 0.001, < 0.0001) views. The angle between the right portal trunk and the transverse portion of the left portal vein was wider on the right anterior oblique views than on the anteroposterior ( p < 0.0001) or right anterior caudal oblique ( p = 0.007) views. The angle between the right anterior and posterior portal branches was wider on the right anterior caudal oblique views than on the anteroposterior ( p < 0.0001) or right anterior oblique ( p = 0.030) views. The right anterior caudal oblique projection provides the best image of the proximal portal vein, and therefore should be obtained whenever possible in preoperative staging of hepatobiliary cancer.

Abstract
Factors influencing postoperative hospital mortality and long-term survival after radical resection of stage IV gallbladder carcinoma remain unclear. The objective of this study was to identify characteristics of patients who are good candidates in terms of surgical risk and long-term survival for radical resection of stage IV gallbladder carcinoma. A retrospective study was made of attempted surgical cure in 72 patients with stage IV gallbladder carcinoma. There were 14 postoperative hospital deaths (19%). Eleven (19%) of the 58 patients discharged from hospital survived for more than 3 years. Multivariate analysis indicated male gender, extended right hepatic lobectomy in a cholestatic liver, and portal vein resection as independent risk factors that correlated with hospital death. Distant metastasis was the sole independent factor that related negatively with long-term survival by multivariate analysis. Subset analysis was performed with combinations of the four independent factors obtained by multivariate analyses. The hospital mortality rate and the 3-year survival rate in the 44 patients without portal vein involvement were 9% and 28%, respectively, and were 3% and 27%, for the 31 women in this group. The highest 3-year survival rate (39%) was observed in the 26 patients without distant metastasis and portal vein involvement, despite a hospital mortality rate of 12%. Better patient selection may improve the outcome of radical surgery for stage IV gallbladder carcinoma. These data may be useful in designing future trials of the surgical treatment of advanced gallbladder carcinoma.

Abstract
OBJECTIVE To investigate whether immunohistochemically demonstrated lymph node micrometastasis has prognostic significance in patients with histologically node-negative (pN0) hilar cholangiocarcinoma. SUMMARY BACKGROUND DATA The clinical significance of immunohistochemically detected lymph node micrometastasis recently has been evaluated in various tumors. However, no reports have addressed this issue with regard to hilar cholangiocarcinoma. METHODS A total of 954 lymph nodes from surgical specimens of 45 patients with histologically node-negative hilar cholangiocarcinoma who underwent macroscopically curative resection were immunostained with monoclonal antibody against cytokeratins 8 and 18. The results were examined for relationships with clinical and pathologic features and with patient survival. RESULTS Lymph node micrometastases were detected immunohistochemically in 11 (24.4%) of the 45 patients, being found in 13 (1.4%) of 954 lymph nodes examined. Of the 13 nodal micrometastases, 11 (84.6%) were found in the N2 regional lymph node group rather than N1. Clinicopathologic features showed no associations with lymph node micrometastases. Survival curves were essentially similar between patients with and without micrometastasis. In addition, the grade of micrometastasis showed no effect on survival. The Cox proportional hazard model identified microscopic venous invasion, microscopic resection margin status, and histologic differentiation as significant prognostic factors in patients with pN0 disease. CONCLUSIONS Lymph node micrometastasis has no survival impact in patients with otherwise node-negative hilar cholangiocarcinoma. The authors do not recommend extensive lymph node sectioning with keratin immunostaining for prognostic evaluation.

Abstract
BACKGROUND Farrar's criteria for cystic duct carcinoma (histopathological diagnosis of a carcinoma strictly limited to the cystic duct) have practical limitations. We propose new "working definition": a gallbladder tumor, the center of which is located in the cystic duct. PATIENTS AND METHODS Between 1980 and 2000 we diagnosed cystic duct carcinoma in 31 patients, 28 of whom (90%) had increased serum bilirubin concentrations. Extrahepatic bile duct resection and cholecystectomy were performed in 10 patients; in others, extended right hepatectomy (16), right hepatectomy (3), and liver bed resection (2) were necessary as well for a potentially curative resection. Additional procedures were portal vein resection (10) and pancreatoduodenectomy (7). RESULTS All tumors were adenocarcinomas. Depth of invasion was T2 in 3 patients, T3 in 12, and T4 in 16. Thirteen patients (42%) had lymph node metastasis. Curative resection was performed in 24 patients (77%). Hospital mortality was 5 of 31 (16%). Actuarial 5-year survival rate excluding hospital deaths was 22%. CONCLUSIONS The proposed "working definition" avoids the problems associated with Farrar's criteria and describes a distinct patient group with an approximately equal proportion of men and women, advanced T stage, but a lower than expected frequency of lymph node metastasis. It establishes a basis for standard reporting of results.

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
An aggressive approach to peritoneal dissemination involves peritonectomy procedures combined with preoperative intraperitoneal chemotherapy, intraoperative chemo-hyperthermia, and postoperative systemic chemotherapy. We have been performing multimodal therapy consisting of peritonectomy plus perioperative chemotherapy for the treatment of patients with peritoneal dissemination. Fifty-seven patients with established peritoneal dissemination from gastric cancer (n = 32), colon cancer (n = 17), ovarian cancer (n = 7), and mesothelioma (n = 1) have been treated with peritonectomy and intraoperative chemo-hyperthermia. Five-year survival rates of patients with gastric and colon cancer were 18% and 38%, respectively. Among various clinical factors, complete tumor resection was the most significant prognostic factor, and the prognosis of patients who underwent complete cytoreduction was significantly better than those who received incomplete cytoreduction. A multimodal therapy consisting of perioperative chemotherapy and peritonectomy with complete cytoreduction may be the most powerful method to treat patients with established peritoneal dissemination.

Abstract
BACKGROUND AND AIMS The mode and degree of tumor spread in gallbladder carcinoma is poorly documented. The present study classifies the patterns of dissemination of this tumor with a focus on surgical strategy. PATIENTS AND METHODS Surgical specimens from 112 patients who underwent curative resection were reviewed. There were stage I, II, III, and IV in 9, 11, 14, and 78 patients, respectively. RESULTS Six types of spread were identified. In the hepatic bed type ( n=20) a large mass in the fundus and body penetrated into the liver through the gallbladder bed with or without contiguous spread to the gastrointestinal tract. The extent of hepatectomy was individualized from wedge resection to extended right hepatectomy based on the clinical findings. In the hepatic hilum type ( n=26) a relatively small tumor in the neck infiltrated the hepatic hilum causing obstructive jaundice. Extended right hepatectomy plus bile duct resection with or without portal vein resection was necessary for curative resection because the tumor had extended into the right portal pedicle, and postoperative hepatic failure was common. In the bed and hilum type ( n=18) a huge mass occupying the entire gallbladder involved both the gallbladder bed and the hepatic hilum. Extended right hepatectomy with combined resection of contiguous spread was necessary for curative resection. In the lymph node type ( n=15) enlarged metastatic lymph nodes were the most prominent feature, and the primary tumor remains limited to the gallbladder in most cases. Extended lymphadenectomy with combined individualized resection was performed. In the cystic duct type ( n=9) a small mass arising from the cystic duct involved the common bile duct. This type presented at an earlier stage than the first four types. In the localized type ( n=24) tumor spread is localized to the gallbladder and presented at the earliest stage of any type. Simple cholecystectomy with or without wedge hepatic resection and regional lymphadenectomy resulted in a satisfactory outcome. Prognosis depends on the stage rather than on the mode of tumor spread. Even in the advanced types favorable results may be obtained in selected patients undergoing radical resection for M0 tumors without portal vein invasion. Success also was achieved in the rare patients with para-aortic lymph node metastases that were not infiltrative. CONCLUSIONS These six types of gallbladder cancer can be diagnosed preoperatively by clinical and radiological examination. This information should assist the surgeon in the choice of operation and predict outcome.

Abstract
In some patients, bile ducts of segments 2 and 3 (B2 and B3) run caudally to the umbilical portion of the left portal vein (UP)--an infraportal course. We aimed to evaluate the frequency and clinical implications of this variation. Between January 1992 and October 2000, 108 patients underwent resection for hilar cholangiocarcinoma. The records of the 6 patients with infraportal left hepatic ducts were evaluated. An infraportal B3 was diagnosed in 6 patients (6%). No patient had an infraportal B2. An infraportal B3 could be demonstrated by computed tomography (CT) before biliary drainage, percutaneous transhepatic or endoscopic cholangiography, portography after percutaneous transhepatic biliary drainage (PTBD) via B3 and CT after PTBD via B3. Four patients (4/6) had a liver bridge covering Rex's recess (B3 not in the bridge). The incidence of the bridge in 75 comparable patients was 9/75. In conclusion, common radiologic methods are sufficient for diagnosis of abnormal biliary anatomy. The presence of a liver bridge over Rex's recess is suggestive of this variation. Separate biliary reconstruction for an infraportal branch is mandatory in an extended right hepatectomy for biliary tract cancer and may be necessary in liver transplantation with segments 2+3 grafting.

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
We have aggressively performed extensive surgery including major liver resection for advanced gallbladder cancer since 1979. The 5-year survival rates for stage IVa and IVb patients after curative resection were 19% and 6%, respectively. Seven patients in the stage IVa group (n = 69) and one in stage IVb (n = 16) have survived for more than 5 years. The hospital mortality rate including all deaths within and over 30 days of curative operation for stage IV gallbladder cancer was 19%. Although radical resection is the only treatment of choice for advanced gallbladder cancer to obtain long-term survival, there are serious problems in extensive surgery. The most important issue is reduction of the hospital mortality rate. Elucidation of the clinical and molecular characteristics leading to potential long-term survival and development of new strategies for the treatment of recurrent tumors are also important issues.

Abstract
BACKGROUND AND AIMS Septic complications after hepatectomy remain a difficult problem. Intra-abdominal sources of postoperative infections are well described in the literature. However, no studies have examined the cause and outcome of bacteremia after hepatectomy. This study evaluated the incidence and outcome of bloodstream infections, bacteremia, after hepatectomy and determined the risk factors associated with the development of this serious complication. PATIENTS AND METHODS Records were retrospectively reviewed of 407 patients who underwent an elective first hepatectomy at Nagoya University Hospital between January 1990 and December 1999. The incidence, cause, outcome, and possible risk factors for bacteremia were examined. RESULTS A total of 403 blood cultures were performed after hepatectomy in 188 patients (46%), and bacteremia was confirmed in 46 (11%). The incidence was significantly different between patients with obstructive jaundice and those without (24% vs. 4%). Multivariate analysis identified four significant independent variables: operative time, age, obstructive jaundice, and large-scale hepatectomy. The most common bacteria isolated were Staphylococci, followed by Enterococci, Klebsiella pneumoniae, and Enterobacter. A probable source of bacteremia was identified in 21 (46%) of the 46 patients. Patients with bacteremia had higher morbidity and mortality rates than patients without bacteremia, and the incidence of organ failure was five to ten times that of patients without bacteremia; the mortality rate was 43% (20/46). CONCLUSIONS Postoperative bacteremia is a common complication of hepatectomy to resect biliary tract carcinoma, especially in older patients with obstructive jaundice undergoing major hepatectomy. In addition, for more than half of patients with bacteremia, no clear source of the infection is identified. Thus blood cultures are mandatory in high-risk patients who spike a fever after hepatectomy to identify the correct pathogen and its antibiotic susceptibility.

Abstract
BACKGROUND Hepaticojejunostomy following hepatobiliary resection has been performed using a Roux-en-Y jejunal limb via the antecolic or the retrocolic-anteduodenal route. However, in morbidly obese patients difficulty arises from the thickened, foreshortened mesentery of the jejunum and from limited mobility due to intra-abdominal fat deposition. METHODS We developed new placement of Roux-en-Y jejunal limb in which the limb is placed via the retrocolic-retrogastric route. Hepaticojejunostomy via this route was performed in 133 obese and nonobese patients with biliary cancer. RESULTS Tension-free anastomosis was successfully performed in all patients. Neither early nor late complications directly related to this new reconstruction route occurred. CONCLUSIONS The retrocolic-retrogastric route is simple and an alternative to the standard methods of biliary reconstruction following hepatobiliary resection. This new placement may circumvent the obesity-related problem.

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
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
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.

Abstract
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.

Abstract
BACKGROUND The diagnostic value of percutaneous transhepatic portography (PTP) for assessing cancer invasion of the portal bifurcation in patients with hilar cholangiocarcinoma has not been studied previously. METHODS From April 1977 to March 1998 combined hepatobiliary and portal vein resection was performed in 45 patients. In 25 patients, PTP was carried out before operation and the resected portal bifurcation was examined histologically. Correlation between portographic and microscopic findings at the portal bifurcation was studied retrospectively. RESULTS Portographic and microscopic findings were classified into three groups (type A, B or C, and grade 0, I or II respectively) according to the findings at the portal bifurcation. There was a significant correlation between the portographic type and degree of cancer invasion (P = 0.0001). In seven of the eight patients with type A portograms, there was no microscopic cancer invasion of the portal bifurcation. In 15 of the 17 patients with type B or C portograms, cancer invasion was found microscopically. All patients with microscopic grade II invasion had type C portograms. CONCLUSION PTP can be used to evaluate cancer invasion of the portal bifurcation with sufficient reliability for preoperative staging of hilar cholangiocarcinoma.

Abstract
Intrahepatic cholangiocarcinomas that secrete macroscopically excessive mucin into the biliary system are rare, and few of the previously reported cases have achieved a curative resection. We defined these tumors as "mucin-producing intrahepatic cholangiocarcinomas" and clarify the optimal preoperative and surgical management for them. Eleven patients with mucin-producing intrahepatic cholangiocarcinomas underwent surgical resection in our department. The clinical, radiologic, surgical, and pathologic findings were studied. The clinical presentation of the 11 patients included repeated abdominal pain, jaundice, and fever. Conventional cholangiographies, such as percutaneous transhepatic cholangiography or endoscopic retrograde cholangiography, could not offer precise information about tumor location and extension because of abundant mucin in the biliary system. Using percutaneous transhepatic biliary drainage (PTBD) and percutaneous transhepatic cholangioscopy (PTCS), we were able to drain the mucin and determine precisely the cancer extension into intrahepatic segmental bile ducts. Based on these findings, various types of liver resection with or without extrahepatic bile duct resection were planned, and 10 patients obtained curative resection. The cumulative 5-year survival rate after curative resection was 78%. In patients with mucin-producing intrahepatic cholangiocarcinoma, PTBD and PTCS are important for evaluating the cancer extension. Rational surgery based on accurate preoperative diagnosis improved the prognosis of patients with this disease.

Abstract
BACKGROUND/AIMS To clarify a correlation between serum alkaline phosphatase (ALP) levels and liver function and regeneration after major hepatectomy. METHODOLOGY Post-operative changes in serum ALP levels were retrospectively examined in 91 non-cirrhotic patients with biliary tract carcinoma who underwent right hepatic lobectomy or more extensive liver resection. In addition, changes in liver volume after resection were assessed in 31 patients who underwent computed tomography before surgery and within 1 month after resection. RESULTS Serum ALP levels reached its nadir on post-operative day 1, followed by a gradual increase until post-operative day 28. In patients with post-hepatectomy liver failure (n = 32), serum ALP levels were significantly lower on days 1, 7, 10, 14, 21, and 28 after resection than in those without such failure (n = 59). Unexpectedly, the volumetric study of the liver showed no significant difference between the two groups in the remnant liver volume after resection. CONCLUSIONS Serum ALP levels can function as an indicator of liver function after hepatectomy, but not reflect morphological regeneration of the liver. Thus, increased ALP levels after hepatectomy may not reflect the cellular proliferation process itself.

Abstract
Fibrolamellar hepatocellular carcinoma (FLHCC), which is quite uncommon in Japan, is known to be frequently associated with lymph node metastasis in Western countries. Herein, we describe a case of a 25 year-old Japanese woman with recurrent FLHCC in the lymph nodes after undergoing right hepatic lobectomy. She underwent a second operation for removal of a recurrent celiac lymph node tumor 23 months after the initial operation. In Japan, the frequency of lymph node metastasis in ordinary hepatocellular carcinoma is only 1.6%, whereas 3 out of 9 (33%) reported domestic FLHCCs including this case had lymph node metastasis. The surgical management of lymph node metastasis in FLHCC is discussed.

Abstract
Our strategy for recurrent tumor after surgical resection for biliary malignancies, especially for hilar cholangiocarcinoma, is described. One hundred and thirty-three patients with hilar cholangiocarcinoma underwent curative resection in our department until November, 1998, and recurrent carcinomas have been pointed out in 73 patients (54.9%). The site of recurrence was peritoneum (21 cases), liver (16 cases), pre-caval and retro-duodenal space (15 cases), hepatic hilum (11 cases), lymph node (9 cases), bone (6 cases), sinus tract of percutaneous transhepatic biliary drainage (PTBD) (5 cases) and so on. Surgical resection was applied to recurrent carcinomas after careful evaluation, and 9 patients underwent surgical resection of the recurrent tumor: sinus tract of PTBD in the abdominal and/or chest wall (4 cases), lymph node (2 cases), liver (1 case), hepaticojejunostomy (1 case) and duodenum (1 case). There were three hospital death patients. Other six patients survived for 16 months on an average (11-20 months) after surgery for recurrent tumor. PTBD for recurrent cancer at the hepatic hilum and gastrojejunostomy for local recurrence around the duodenum improved quality of life of patients. Radiation therapy for bone metastasis or local recurrence at the hepatic hilum was sometimes very effective. Effect of systemic or transarterial chemotherapy is still unknown.

Abstract
We reviewed the records of 64 patients with resected intrahepatic cholangiocarcinoma (ICC) according to the macroscopic classification proposed by the Liver Cancer Study Group of Japan, in which ICC is classified into three types based on the macroscopic appearance of the cut sur-face of the tumor: mass-forming, periductal-infiltrating, and intraductal growth types. There were 24 patients with the periductal-infiltrating type, 28 with the mass-forming type, and 12 with the intraductal growth type. The mass-forming type essentially showed expansive growth irrespective of hilar invasion. The periductal-infiltrating type of tumor exhibited diffuse infiltration along the portal pedicle, and preoperative planning of the resection procedure was similar to that for primary bile duct carcinoma of the hepatic confluence. Vascular resection and reconstruction was required in some patients with advanced disease. In the intraductal growth type of tumor, precise determination of tumor extent was difficult because of the ambiguity caused by abundant mucin secreted by the tumor and/or by the superficial mucosal spread of the tumor along the bile duct. Percutaneous transhepatic cholangioscopy provided the most reliable information for designing the operative procedure. The macroscopic classification is useful for preoperative diagnosis of tumor extent and for planning the surgical procedure.

Abstract
INTRODUCTION Despite advances in antibiotic prophylaxis, postoperative wound infection remains a major source of morbidity after digestive surgery. Its prevention is a challenging problem, especially in high-risk patients. The authors introduced a new method to prevent surgical wound infections and evaluated its efficacy in a prospective, randomized trial in markedly high-risk patients. METHODS Patients with biliary tract carcinoma who were scheduled to undergo combined liver and extrahepatic bile duct resection with biliary reconstruction were randomly assigned to one of two groups, well matched in terms of clinical characteristics at baseline. In one group the new treatment was employed (sealed group, n=31), and in the other the wound was treated in the usual fashion (open group, n=28). In the sealed group, povidone-iodine gel was administered to the subcutaneous tissue, and the skin and peritoneum were approximated with a continuous suture. Wound infection was registered up to 30 days after surgery. RESULTS Wound infection occurred in 18 patients: 5 (16%) patients in the sealed group and 13 (46%) in the open group (P<0.05). All 18 underwent preoperative percutaneous transhepatic biliary drainage and had positive bile culture findings. In 13 of these 18 patients (72%) the microorganisms isolated from the infected wound were identical to those in the bile. CONCLUSIONS Our results confirm the close association between infected bile and wound infection in hepatobiliary surgery. Our new method, "direct wound sealing," is simple, easy to perform, virtually cost-free, and has the potential to prevent wound infections even in markedly high-risk patients.

Abstract
Seven reports of paraaortic lymphadenectomy for advanced carcinoma of the gallbladder were reviewed and positive paraaortic nodes were found in 20-40% of the resected patients and 10-15% of those with subserosal cancer invasion. The rate of patients with positive paraaortic nodes/all patients with positive nodes was 30-50%. Paraaortic lymphadenectomy did not improve the surgical outcome, and most of the patients with positive paraaortic nodes died within 1 year even after aggressive surgery with extensive lymph node dissection. Therefore it is important to clarify the value of paraaortic lymph node dissection for patients with possibly positive paraaortic node metastasis and those with histologically positive nodes excluding the paraaortic area. Although pancreatoduodenectomy for prophylactic lymphadenectomy around the head of the pancreas has been carried out in some institutions, the procedure does not seem to be effective because the main lymphatic route from the gallbladder has a direct connection with the paraaortic nodes via the pericholedochal, periportal, and/or the posterior nodes along the common hepatic artery. The present authors recommend a D2 plus paraaortic lymph node dissection (ext D2) as a standard surgical strategy for carcinoma of the gallbladder.

Abstract
Recent progress in surgical techniques for and the perioperative management of hilar cholangiocarcinoma has led to improved outcomes for aggressive liver and bile duct resections, which, however, still show considerable morbidity and mortality. In this article, the results of pioneers' attempts in hepatobiliary surgery for difficult hilar cholangiocarcinomas are reviewed. It is recommended that curative hepatobiliary resection should be performed for hilar cholangiocarcinoma, with careful preoperative management of patients complicated with several difficult conditions.

Abstract
Differences in surgical strategies for carcinoma of the pancreas, especially the head of the pancreas, between Japan and western countries are described. In Japan, pancreatoduodenectomy (PD) or pylorus-preserving PD, accompanied by extensive lymph node and extra-pancreatic nerve plexus dissection, is performed for this difficult disease. Combined resection of the portal vein is also done when needed (radical resection). In western countries, a standard PD does not include extensive lymph node dissection and portal vein resection (standard resection). Although some Japanese surgeons reported about 30% postoperative 5-year survival rates after radical resection and some American surgeons achieved about 20% 5-year survival rates after standard resection, there are some problems with comparison of these results. Surgeons in Japan and western countries use different staging systems, namely, the classifications of the Japanese Pancreas Society and the Union of Internationale Contre le Cancer (UICC). It is essential to establish a more accurate international staging system to scientifically evaluate the difference in surgical results between Japan and western countries.
