Comparison of an Inside Stent and a Fully Covered Self-Expandable Metallic Stent as Preoperative Biliary Drainage for Patients with Resectable Perihilar Cholangiocarcinoma. Can J Gastroenterol Hepatol 2022; 2022:3005210. [PMID: 35845721 PMCID: PMC9277217 DOI: 10.1155/2022/3005210] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/11/2022] [Revised: 04/29/2022] [Accepted: 05/23/2022] [Indexed: 11/17/2022] Open
Abstract
Background There is a need for a more tolerable preoperative biliary drainage (PBD) method for perihilar cholangiocarcinoma (PHCC). In recent years, inside stents (ISs) have attracted attention as a less suffering PBD method. Few studies have compared IS with a fully covered self-expandable metallic stent (FCSEMS) as PBD for resectable PHCC. The aim of this study is to compare them. Methods This study involved 86 consecutive patients (IS: 51; FCSEMS: 35). The recurrent biliary obstruction (RBO) rate until undergoing surgery or being diagnosed as unresectable, time to RBO, factors related to RBO, incidence of adverse events related to endoscopic retrograde cholangiography, and postoperative complications associated with each stent were evaluated retrospectively. Results There was no significant difference between the two groups in the incidence of adverse events after stent insertion. After propensity score matching, the mean (SD) time to RBO was 37.9 (30.2) days in the IS group and 45.1 (35.1) days in the FCSEMS group, with no significant difference (P=0.912, log-rank test). A total of 7/51 patients in the IS group and 3/35 patients in the FCSEMS group developed RBO. The only risk factor for RBO was bile duct obstruction of the future excisional liver lobe(s) due to stenting (HR 29.8, P=0.008) in the FCSEMS group, but risk factors could not be indicated in the IS group. There was no significant difference in the incidence of bile leakage or liver failure. In contrast, pancreatic fistula was significantly more common in the FCSEMS group (13/23 patients) than in the IS group (3/28 patients) (P < 0.001), especially in patients who did not undergo pancreatectomy (P=0.001). Conclusions As PBD, both IS and FCSEMS achieved low RBO rates. Compared with FCSEMS, IS shows no difference in RBO rate, is associated with fewer postoperative complications, and is considered an appropriate means of PBD for resectable PHCC. This trail is registered with UMIN000025631.

Abstract
Background Prevention of posthepatectomy liver failure is a prerequisite for improving the postoperative outcome of perihilar cholangiocarcinoma. From this perspective, appropriate assessment of future liver remnant (FLR) function and the optimized preparation are mandatory. Summary FLR volume ratio using CT volumetry based on 3-dimensional vascular imaging is the current assessment yardstick and is sufficient for assessing a normal liver. However, in a liver with underling parenchymal disease such as fibrosis or prolonged jaundice, weighing up the degree of liver damage against the FLR volume ratio is necessary to know the real FLR function. For this purpose, the indocyanine green (ICG) clearance test, monoethylglycinexylidide (MEGX) test, liver maximum capacity (LiMAX) test, 99mTc-labeled galactosyl human serum albumin (99mTc-GSA) scintigraphy, albumin-bilirubin (ALBI) grade, and ALPlat (albumin × platelets) criterion are used. After the optimization of FLR function by means of portal vein embolization or associating liver partition and PVL (portal vein ligation) for staged hepatectomy (ALPPS), SPECT scintigraphy with either 99mTc-GSA or 99mTc-mebrofenin compensates for misestimation due to the regional heterogeneity of liver function. The role of preoperative biliary drainage has long been debated, with the associated complications having led to a lack of approval. However, the recent establishment of safety and an improvement in success rates of endoscopic biliary drainage seem to be changing the awareness of the importance of biliary drainage. Key Messages Appropriate selection of an assessment method is of prime importance to predict the FLR function according to the preoperative condition of the liver. Preoperative biliary drainage in patients with perihilar cholangiocarcinoma is gaining support due to the increasing safety and success rate, especially in patients who need optimization of their liver function before hepatectomy.

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

Abstract
BACKGROUND Hilar cholangiocarcinoma (HCCA) is a rare tumor, usually associated with obstructive jaundice and unfavorable prognosis. Obstructive jaundice can affect the liver, kidney, heart, and the immune system of the patients. Currently, controversy exists in whether preoperative biliary drainage (PBD) is of any benefit to the patients, and the best way for PBD in patients with resectable HCCA of malignant biliary obstruction remains to be determined. OBJECTIVES To compare the clinical outcomes and effectiveness of endoscopic biliary drainage (EBD) treatment with those of percutaneous transhepatic biliary drainage (PTBD) treatment in patients with malignant biliary obstruction caused by resectable HCCA. MATERIALS AND METHODS The databases including MEDLINE, EMBASE, PubMed, CBM (China Biological Medicine Database), and CNKI were employed to identify the clinic trials on EBD versus PTBD for malignant biliary obstruction associated with resectable HCCA from January 2008 to October 2017. A systematic review and meta-analysis were carried out. RESULTS Six trials were identified and included in this study. Overall, the differences in technical success rate, R0 resection, incidence of total complication after resection, postoperative hospitalization time, resection time, and recurrence were not statistically significant between the EBD group and PTBD group (all P > .05). However, the incidence of total complications after EBD treatment is higher than that after PTBD treatment (P < .05). CONCLUSION For patients with obstructive jaundice associated with HCCA, current evidence indicate no superiority of PTBD over EBD regarding clinical feasibility and success rate, but data suggest a better clinical safety of PTBD compared with EBD in short-term postoperation. In long-term evaluation, the differences in clinical outcomes are not statistically significant between PTBD and EBD.

Abstract
BACKGROUND The role of preoperative biliary drainage (PBD) for hilar cholangiocarcinoma (HCC) remains unclear. The aim of this meta-analysis is to investigate the role of PBD in the treatment of potentially resectable HCC. METHODS All studies reporting outcomes on patients with PBD vs without PBD were included. A systematic literature search was performed in PubMed, Embase, and the Cochrane Library for studies published between 1980 and 2016. RESULTS Initial search identified 667 articles. Only 9 studies met the inclusion criteria and were included in this analysis. No significant differences in mortality were observed between the two groups (RR = 0,935; 95% CI = 0,612 to 1429; p = 0,463). Overall morbidity was significantly higher in PBD group (RR = 1266; 95% CI = 1039 to 1543; p = 0,011). No significant differences in transfusion rate, hospital stay, anastomotic leaks, abdominal collections and operative time, were found. Wound infections were significantly higher in PBD group. CONCLUSIONS PBD seems to be associated with higher postoperative morbidity and increases the risk of wound infections. Further prospective studies are needed to better define the impact of PBD in outcomes after surgery for hilar cholangiocarcinoma.

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

Abstract
BACKGROUND The need for routine use of preoperative biliary drainage (PBD) for major liver resection in jaundiced patients has recently been questioned. METHODS We present our experience of 22 consecutive patients with hilar biliary obstruction who underwent major liver resection without PBD between January 2007 and January 2011. RESULTS Twenty-two patients with hilar biliary obstruction underwent major liver resection without PBD over a 4-year period; nineteen had malignant and 3 benign hilar strictures. Fifteen patients underwent right hepatectomy (7) or right trisectionectomy (8) and seven underwent left hepatectomy. Segment 4a was spared in all patients who underwent right trisectionectomy. Six patients had concomitant portal vein resection. Fourteen patients had varying degrees of lobar atrophy. The median preoperative bilirubin was 18 mg % (range 9.1 to 27 mg %). The median blood transfusion requirement was 2 units (range 1-6). There was one postoperative death from portal vein thrombosis. Three patients who underwent greater than 50 % resection developed postoperative ascites. CONCLUSIONS Major liver resection leaving a liver remnant of 50 % is safe in jaundiced patients without PBD even when portal vein reconstruction is necessary. PBD should be used selectively.

Preoperative biliary drainage before resection for hilar cholangiocarcinoma: whether or not? A systematic review. Dig Dis Sci 2011; 56:663-72.

Abstract
BACKGROUND The value of preoperative biliary drainage (PBD) before resection for hilar cholangiocarcinoma (HCCA) is still controversial nowadays. The objective of this review is to summarize quantitatively the evidence related to this issue. METHODS Two investigators independently searched the Medline, Embase, Academic Search Premier (EBSCO), Chinese BioMedical Literature on disc (CBMdisc), and Chinese Medical Current Contents (CMCC) databases. Eleven studies with a total number of 711 HCCA cases were included. Comparison was made of PBD versus no PBD in HCCA patients undergoing surgical resection. Outcome measures were postoperative complications, in-hospital death rate, postoperative infectious complications, and postoperative hospital stay. RESULTS There was no difference in death rate or postoperative hospital stay between the two treatment modalities. However, the overall postoperative complication rate and postoperative infectious complication rate were significantly adversely affected by PBD compared with surgery without PBD. In postoperative complications analysis, ten studies including 442 patients who underwent PBD and 233 patients who had no PBD were estimated. The odds ratio (OR) for postoperative morbidity was 1.67: 95% confidence interval (CI) [1.17, 2.39]. In postoperative mortality analysis, ten studies including 422 patients who underwent PBD and 238 patients who had no PBD were estimated. The OR for postoperative mortality was 0.70: 95% CI [0.41, 1.19]. In postoperative infectious complications analysis, five studies including 134 patients who underwent PBD and 122 patients who had no PBD were estimated. The OR for infectious morbidity was 2.17: 95% CI [1.24, 3.80]. In postoperative hospital stay analysis, only three studies with 84 patients who underwent PBD and 65 patients who had no PBD were estimated; the weighted mean difference (WMD) for postoperative hospital stay was 5.37 days: 95% CI [-1.78, 12.52 days]. CONCLUSIONS This systematic review could not provide evidence for a clinical benefit of using PBD in jaundiced patients with HCCA planned for surgery. Preoperative drainage should not routinely be performed in patients with proximal bile duct cancer scheduled for surgical resection. Because of the lack of uniformity of this analysis, randomized controlled trials (RCTs) with large sample size and improved PBD techniques should be carried out to confirm our results.

Abstract
BACKGROUND The aim of the study was to clarify the incidence, risk factors and treatment of percutaneous transhepatic biliary drainage (PTBD) catheter tract recurrence in patients with resected cholangiocarcinoma. METHODS The medical records of 445 patients with perihilar and distal cholangiocarcinoma who underwent resection following PTBD were reviewed retrospectively. RESULTS PTBD catheter tract recurrence was detected in 23 patients (5.2 per cent). The mean(s.d.) interval between surgery and onset of the recurrence was 14.4(13.8) months. On multivariable analysis, duration of PTBD (60 days or more), multiple PTBD catheters and macroscopic papillary tumour type were identified as independent risk factors. In four patients with synchronous metastasis, the PTBD sinus tract was resected simultaneously, at the time of initial surgery. Of 19 patients with metachronous metastasis, 15 underwent surgical resection of the metastasis. Survival of the 23 patients with PTBD catheter tract recurrence was poorer than that of the 422 patients without recurrence (median 22.8 versus 27.3 months; P = 0.095). Even after surgical resection of PTBD catheter tract recurrence, survival was poor. CONCLUSION PTBD catheter tract recurrence is not unusual. The prognosis for these patients is generally poor, even after resection. To prevent this troublesome complication, endoscopic biliary drainage is first recommended when drainage is indicated.

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

Abstract
BACKGROUND A few authors have reported the value of multidetector row CT (MDCT) for evaluating the longitudinal extent of cholangiocarcinoma. They have not focused on CT attenuation of a tumor and actual tumor extent along the bile ducts. We designed the present study to analyze attenuation. METHODS Between January 2003 and July 2005, 113 consecutive patients with cholangiocarcinoma underwent a surgical resection following MDCT. Of these MDCT studies, 73 (perihilar cholangiocarcinoma, n = 62; middle and distal cholangiocarcinoma, n = 11) were suitable for analysis, and the patients were enrolled in the study. Patients were divided according to tumor hypoattenuation and hyperattenuation on MDCT. Histologic differentiation, desmoplastic reaction, and vascular density were microscopically compared with the tumor attenuation to differentiate the characteristics of the attenuation. The extent of cancer along the bile duct diagnosed by MDCT was compared with the actual extent determined by the microscopic findings. RESULTS Hyperattenuated tumor was observed in 40 patients. There was no difference in histologic differentiation, desmoplastic reaction, or vascular density between the hyperattenuated and hypoattenuated cholangiocarcinomas. Neither the proximal nor the distal borders between the normal and thickened bile duct wall could be determined in the 33 patients with hypoattenuated tumor; in contrast, an accurate assessment of extent of tumor was obtained in 76% of the proximal borders and 82% of the distal borders in the 40 patients with hyperattenuated tumor. CONCLUSIONS Although the cause of the difference between the hyperattenuated and hypoattenuated cholangiocarcinoma still is unclear, MDCT can be an alternative to direct cholangiography in selected patients with hyperattenuated cholangiocarcinoma.

Abstract
Of the patients who underwent resection of hilar cholangiocarcinoma, those who received palliative surgery, or could not be followed up clinicopathologically, were excluded from this study. In the remaining 37 patients, the cumulative postoperative survival rate (simply referred to as the cumulative survival rate below) was analyzed according to gross types, histopathological parameters, final stages, and final curability. These patients showed a 5-year survival rate of 17.7% and a 50% survival of 2.2 years. By gross type, patients with a localized papillary or nodular expansion type tended to have a better survival rate than those with an invasive papillary or nodular expansion type. A greater histological depth of invasion tended to be associated with a poorer prognosis: the s(-) group, that is, a group of patients without serosal exposure of cancer (invasion depths of m, fm, and ss) had a significantly better prognosis than the s(+) group, a group of patients with serosal exposure of cancer (invasion depths of se and si). Other histopathological parameters, such as ly, pn, pHinf, pHM, and pEM, were associated with significant prognostic differences. By final stage, the stage I/II group and stage III or higher group showed a particularly significant difference in prognosis. By final curability, the curability A/B group had a significantly better prognosis than the curability C group. Taken together, surgery providing curability A and B promises a good long-term prognosis. Therefore, it is important that efforts are made to detect cancer early, adequately evaluate the degree of cancer extension, and determine the extent of resection and the surgical technique.

Abstract
OBJECTIVE To clarify the optimal surgical strategy for Bismuth type I and II hilar cholangiocarcinomas. SUMMARY BACKGROUND DATA Local or hilar resections is often performed for Bismuth type I and II tumors; however, reported outcomes have been unsatisfactory with a high recurrence and low survival rate. To improve survival, some authors have recommended right hepatectomy. However, the clinical value of this approach has not been validated. METHODS Records of 54 consecutive patients who underwent resection of a Bismuth type I or II hilar cholangiocarcinoma were analyzed retrospectively. Through 1996, bile duct resection or the smallest necessary hepatic segmentectomy was performed. Beginning in 1997, choice of resection was based on the cholangiographic tumor type. For nodular or infiltrating tumor, right hepatectomy was indicated; for papillary tumor, bile duct resection with or without limited hepatectomy was chosen. RESULTS Right hepatectomy was performed in 5 (20.8%) of 24 patients through 1996 and was done in 22 (73.3%) of 30 patients from 1997 (P = 0.0003). In patients without pM1 disease, R0 resection was achieved more frequently in the later period than in the earlier period (23 of 24 = 95.8% vs. 13 of 21 = 61.9%, P = 0.0073), which lead to better survival (5-year survival, 44.3% vs. 25.0%, P = 0.0495). In the 31 patients with nodular or infiltrating tumor, who tolerated surgery and did not have pM1 disease, survival was better in the 18 patients who underwent right hepatectomy than in those who did not (5-year survival, 62.9% vs. 23.1%, P = 0.0030). In cases of papillary tumor, bile duct resection with or without limited hepatectomy was sufficient to improve long-term survival. CONCLUSIONS The surgical approach to Bismuth type I and II hilar cholangiocarcinomas should be determined according to cholangiographic tumor type. For nodular and infiltrating tumors, right hepatectomy is essential; for papillary tumor, bile duct resection with or without limited hepatectomy is adequate.

Abstract
AIM In patients with malignant hilar obstruction, liver resection is associated with an increased risk of postoperative liver failure attributed to the need for major liver resection in a context of obstructive jaundice. To overcome this issue, most authors recommend preoperative biliary drainage (PBD). However, PBD carries risks of its own, including, primarily, sepsis and, more rarely, tumor seeding, bile peritonitis, and hemobilia. We, unlike most authors, have not used routine PBD before liver resection in jaundiced patients. MATERIAL AND METHODS Our series includes 62 patients who underwent major liver resection for cholangiocarcinoma; 33 of these had elevated bilirubin (60-470 micromol/l) and were operated without PBD. There were 43 extended right hepatectomies and 18 extended left hepatectomies. RESULTS Hospital deaths occurred in 5 patients (8%) including 3 of 33 jaundiced patients (9%, ns). All deaths occurred after extended right hepatectomy (12%), including 3 patients with a serum bilirubin level above 300 micromol/l and 2 with normal bilirubin. There were no deaths after left-sided resections, whatever the level of bilirubin. CONCLUSIONS PBD can be omitted in the following situations: recent onset jaundice (<2-3 weeks), total bilirubin <200 micromol/l, no previous endoscopic or transhepatic cholangiography, absence of sepsis, future liver remnant >40%. These criteria include most patients requiring left-sided resections and selected patients requiring right-sided resections. In other cases, PBD is required, associated with portal vein embolization in the event of a small future liver remnant.

Abstract
Hilar cholangiocarcinomas grow slowly, and metastases occur late in the natural history. Surgical cure and long-term survival have been demonstrated, when resection margins are clear. Preoperative biliary drainage has been proposed as a way to improve liver function before surgery, and to reduce post-surgical complications. Percutaneous transhepatic biliary drainage (PTBD) with multiple drains was previously the preferred method for the preoperative relief of obstructive jaundice. However, the introduction of percutaneous transhepatic portal vein embolization (PTPE) and wider resection has changed preoperative drainage strategies. Drainage is currently performed only for liver lobes that will remain after resection, and for areas of segmental cholangitis. Endoscopic biliary drainage (EBD) is less invasive than PTBD. Among EBD techniques, endoscopic nasobiliary drainage (ENBD) is preferable to endoscopic biliary stenting (EBS), because secondary cholangitis (due to the retrograde flow of duodenal fluid into the biliary tree) does not occur. ENBD needs to be converted to PTBD in patients with segmental cholangitis, those with a prolonged need for drainage, or when the extent of longitudinal tumor extension is not sufficiently well characterized.

Abstract
Since extrahepatic bile duct cancer is difficult to diagnose and to cure, a safe and radical surgical strategy is needed. In this review, the modes of infiltration and spread of extrahepatic bile duct cancer and surgical strategy are discussed. Extended hemihepatectomy, with or without pancreatoduodenectomy (PD), plus extrahepatic bile duct resection and regional lymphadenectomy has recently been recognized as the standard curative treatment for hilar bile duct cancer. On the other hand, PD is the choice of treatment for middle and distal bile duct cancer. Major hepatectomy concomitant with PD (hepatopancreatoduodenectomy) has been applied to selected patients with widespread tumors. Preoperative biliary drainage (BD) followed by portal vein embolization (PVE) enables major hepatectomy in patients with hilar bile duct cancer without mortality. BD should be performed considering the surgical procedure, especially, in patients with separated intrahepatic bile ducts caused by hilar bile duct cancer. Right or left trisectoriectomy are indicated according to the tumor spread and biliary anatomy. As a result, extended radical resection offers a chance for cure of hilar bile duct cancer with improved resectability, curability, and a 5-year survival rate of 40%. A 5-year survival rate has ranged from 24% to 39% after PD for middle and distal bile duct cancer.

Abstract
Hilar cholangiocarcinoma is a rare tumor. Surgery remains the only treatment to prolong survival. There is a correlation between the extent of diagnostic work-up and the achieved resection rates. Moreover, diagnostic work-up may contribute to an improvement of the surgical technique. Due to the perihilar fibrosis, the extent of the central lesion may be overestimated, which may lead to exclude the patient from potentially curative surgery. En bloc resection is requested to achieve tumor-free resection margins. The prognosis of the patients treated with surgery is strongly influenced by negative resection margins. According to our experience, 5-year survival of 78/111 patients with tumor resection (resection rate 71%) has been 30%. Forty-eight percent of the patients with curative en bloc resection of tumor and liver survived for more than 5 years. Perioperative mortality was 5.1%. The available data are supposed to reflect the results of centers with high caseload and not the general situation.

Abstract
HC is an uncommon--although readily recognizable-clinical entity. Although current hepatobiliary imaging has improved, accurate staging of HC preoperatively is difficult. In patients who have potentially resectable HC, careful preoperative preparation with biliary drainage, portal vein embolization, or both is indicated because major hepatic resection has become an essential component of surgical treatment, and these interventions may reduce perioperative risks. Currently, lobar or extended lobar hepatic and bile duct resection, regional lymphadenectomy, and Roux-en-Y hepaticojejunostomy are the treatments of choice for HC. Whether major vascular resection coupled with these procedures or hepatic transplantation in selected patients will improve overall survival is unknown. Finally, current outcomes dictate investigation of effective adjuvant therapy.

Abstract
BACKGROUND The indication for a hepatopancreatoduodenectomy (HPD) in patients with advanced biliary tract cancer is still controversial, because this aggressive surgery might be associated with high mortality and morbidity rates. In this study, we review our experience with HPD for advanced biliary tract cancer, and seek to define the indication for HPD. METHODS Eleven patients with biliary tract cancer underwent HPD at Wakayama Medical University Hospital between 1986 and 2004. Univariate analysis was used to assess independent variables of the mortality and morbidity associated with HPD. RESULTS The rates of mortality and morbidity were 18% and 82%, respectively. Univariate analysis showed that the total serum bilirubin level before surgery and the hepatic parenchymal resection of more than two Healey's segments correlated significantly with an increased risk of severe complications (P = 0.044, 0.0152, respectively). The 1-, 2-, and 3-year survival rates were 44%, 33%, and 11%, respectively. CONCLUSIONS Hepatopancreatoduodenectomy might offer a chance of long survival by yielding a tumor-free margin in selected patients who are able to tolerate such an aggressive operation, but the indication for this aggressive surgery should be carefully considered.

Abstract
OBJECTIVE To investigate the effect of bile replacement following percutaneous transhepatic biliary drainage, ie, external drainage, on intestinal permeability, integrity, and microflora in a clinical setting. SUMMARY BACKGROUND DATA Several authors have reported that internal biliary drainage is superior to external drainage. However, it is unclear whether bile replacement following external drainage is beneficial. METHODS Twenty-five patients with biliary cancer underwent percutaneous transhepatic biliary drainage (PTBD) as a part of presurgical management. All externally drained bile was replaced either per os or by administration through a nasoduodenal tube. The interval between PTBD and the beginning of bile replacement was 21.3 +/- 19.7 days, and the length of bile replacement was 20.7 +/- 9.6 days. The lactulose-mannitol test, measurement of serum diamine oxidase (DAO) activity, and analyses of fecal microflora and organic acids were performed before and after bile replacement. RESULTS The volume of externally drained bile varied widely from patient to patient, ranging from 220 +/- 106 mL/d to 1616 +/- 394 mL/d (mean, 714 +/- 346 mL/d). Biliary concentrations of bile acids, cholesterol, and phospholipids increased significantly after bile replacement. The lactulose-mannitol (L/M) ratio decreased from 0.063 +/- 0.060 before bile replacement to 0.038 +/- 0.032 after bile replacement (P < 0.05). Serum DAO activity increased from 3.9 +/- 1.4 U/L before bile replacement to 5.1 +/- 1.6 U/L after bile replacement (P < 0.005), and the magnitude of change in serum DAO activity correlated with the length of bile replacement (r = 0.483, P < 0.05). Neither the L/M ratios nor serum DAO activities before bile replacement correlated with the interval between PTBD and the beginning of bile replacement. Fecal microflora and organic acids were unchanged. CONCLUSION Impaired intestinal barrier function does not recover by PTBD without bile replacement. Bile replacement during external biliary drainage can restore the intestinal barrier function in patients with biliary obstruction, primarily due to repair of physical damage to the intestinal mucosa. Our results support the hypothesis that bile replacement during external drainage is beneficial.

Abstract
Proximal bile duct cancer poses a difficult surgical problem in hepatobiliary surgery because of its location, patterns of spread, and required extent of resection for complete excision. This article focuses on the anatomic and pathologic issues that are associated with proximal bile duct cancer and assesses the roles of partial hepatectomy and bile duct resection in the surgical management of this cancer. It is hoped that this article provides clinical evidence that supports hepatic resection as an essential and efficacious component of the surgical management of perihilar cholangiocarcinoma in selected patients.

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
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
BACKGROUND Interleukin (IL) 6 is one of the important components of the early signalling pathways leading to liver regeneration, and has been detected in the bile after liver transplantation. IL-6 concentrations in the bile were studied in an attempt to predict liver function after major hepatectomy for biliary tract carcinoma. METHODS This study involved 24 patients without cirrhosis who underwent major hepatectomy for biliary tract carcinoma. The bile was sampled regularly through external biliary drainage tubes. IL-6 concentrations in bile and serum were measured using an enzyme-linked immunosorbent assay. RESULTS Bile IL-6 concentrations increased 37-fold (from mean(s.e.) 56(13) pg/ml before hepatectomy to 2071(398) pg/ml on day 1 after operation) in patients without liver failure after hepatectomy (n = 18) and increased sevenfold (from 71(24) to 530(76) pg/ml) in patients with liver failure after hepatectomy (n = 6). The values were significantly lower in patients with liver failure than in those without liver failure (P < 0.05). The bile IL-6 concentration on day 1 after operation exhibited a significant negative correlation with the maximum serum total bilirubin concentration after hepatectomy. Although serum IL-6 concentrations were also increased in both groups after hepatectomy, there was no significant correlation with postoperative liver function. CONCLUSION Increased bile IL-6 concentrations after hepatectomy may reflect liver regenerative capacity. Measurement of bile IL-6 concentrations may be clinically useful for the early identification of liver failure after hepatectomy.

Abstract
BACKGROUND/AIMS We have shown that hepatocyte growth factor is excreted into bile after hepatectomy in patients with biliary tract carcinoma. However, it is not certain whether hepatocyte growth factor in bile is an active molecule or degradation products. METHODS Bile was obtained from five patients after hepatobiliary resection. Bile hepatocyte growth factor was purified on a heparin-Sepharose column and subjected to Western blotting. It was also tested for growth-stimulating activity with rat primary cultured hepatocytes. Biles from 50 patients who underwent various types of hepatobiliary resections were examined with respect to hepatocyte growth factor by an enzyme-linked immunosorbent assay. RESULTS Upon Western blotting following nonreducing electrophoresis, the purified bile hepatocyte growth factor showed an 85 kDa peptide corresponding to native hepatocyte growth factor. Under reducing conditions, it showed bands of a-subunit at 69 kDa and beta-subunit at 34 kDa with corresponding monoclonal antibodies. The purified bile hepatocyte growth factor stimulated the [3H]thymidine incorporation into primary cultured hepatocytes with a specific activity comparable to recombinant human hepatocyte growth factor. It was observed that the levels of bile hepatocyte growth factor increased after the various types of hepatobiliary resections, including bile duct resection without hepatectomy. CONCLUSIONS The human bile obtained after hepatobiliary resection contains active hepatocyte growth factor that can stimulate hepatocyte growth. Bile hepatocyte growth factor increased not only in hepatectomy but in bile duct resection. These results suggest that the biliary tract system may play an important role in the production of bile hepatocyte growth factor.

Abstract
OBJECTIVE To elucidate changes in portal blood flow (PBF) after percutaneous transhepatic portal vein embolization and their possible association with hypertrophy of the nonembolized hepatic segments. SUMMARY BACKGROUND DATA The increase in PBF of the nonembolized hepatic segments after embolization is presumed to trigger hypertrophy of these segments. However, changes in PBF after embolization have not been investigated, and their extent remains unknown. METHODS The authors prospectively measured PBF velocity, using color Doppler ultrasound, in 21 patients without cirrhosis who underwent embolization of the right portal vein or the right portal vein plus the left medial portal branch. Liver hypertrophy was assessed with a volumetric study using computed tomography. RESULTS The PBF velocity significantly increased, from 11.1+/-3.6 cm/sec before embolization to 20.1+/-7 cm/sec 1 day after embolization. Subsequently, the velocity gradually decreased, but it remained significantly elevated until postembolization day 14. The volume of the nonembolized segments significantly increased from 370+/-141 cm3 to 488+/- 145 cm3. The hypertrophy rate (cm3/day) of the nonembolized segments after embolization correlated closely with the extent of increase in the PBF velocity, expressed as the velocity on day 1 divided by the velocity before embolization. The hypertrophy rate had a significant correlation with the absolute value of the PBF velocity on day 1, but its correlation coefficient was low. No significant correlations were observed between the hypertrophy rate and other clinical variables. CONCLUSIONS The hypertrophy rate of nonembolized hepatic segments after embolization is predictable from the extent of the increase in the PBF velocity. This can be estimated easily and noninvasively with Doppler ultrasound 1 day after embolization.

Abstract
OBJECTIVE To clarify the importance of different patterns of infiltration at the proximal border of hilar bile duct carcinomas. SUMMARY BACKGROUND DATA There are few detailed pathologic studies on the proximal resection margins in patients with hilar bile duct carcinoma. METHODS Serial sections of 62 specimens of resected hilar bile duct carcinoma were examined histologically to determine the involved layers and routes of invasion at the proximal border. The degree of cancer extension was determined, and the relation between the length of the tumor-free resection margin and postoperative anastomotic recurrences was analyzed. RESULTS Mucosal extension was predominant in papillary and nodular tumors, but submucosal extension was predominant in diffusely infiltrating and nodular-infiltrating tumors. Submucosal extension usually consisted of direct or lymphatic invasion. The mean length of submucosal extension was 6.0 mm. Superficial spread of cancer, defined as mucosal extension of more than 20 mm from the main lesion, was seen in 8 specimens. No patient had an anastomotic recurrence when the tumor-free resection margin was greater than 5 mm. CONCLUSIONS The pattern of infiltration at the proximal border of resected hilar bile duct carcinomas is closely related to the gross tumor type. The length of submucosal extension is usually less than 10 mm. Superficial spread of cancer is seen in more than 10% of cases. A tumor-free proximal resection margin of 5 mm appears to be adequate in hilar bile duct carcinoma.
