Abstract
Background The long-term prognosis after surgery of patients with hepatocellular carcinoma (HCC) and extrahepatic bile duct tumor thrombus (Ex-BDTT) remains unknown. We aimed to identify the surgical outcomes of patients with HCC and Ex-BDTT. Methods A total of 138 patients with Ex-BDTT who underwent hepatectomy with preservation of the extrahepatic bile duct from five large hospitals in China between January 2009 and December 2017 were included. The Cox proportional hazards model was used to analyze overall survival (OS) and recurrence-free survival (RFS). Results With a median follow-up of 60 months (range, 1-127.8 months), the median OS and RFS of the patients were 28.6 and 8.9 months, respectively. The 1-, 3-, and 5-year OS rates of HCC patients with Ex-BDTT were 71.7%, 41.2%, and 33.5%, respectively, and the corresponding RFS rates were 43.5%, 21.7%, and 20.0%, respectively. Multivariate analysis identified that major hepatectomy, R0 resection, and major vascular invasion were independent prognostic factors for OS and RFS. In addition, preoperative serum total bilirubin ≥ 4.2 mg/dL was an independent prognostic factor for RFS. Conclusion Major hepatectomy with preservation of the extrahepatic bile duct can provide favorable long-term survival for HCC patients with Ex-BDTT.

Liu H, Shi C, Yan Z, Luo M. A single-center retrospective study comparing safety and efficacy of endoscopic biliary stenting only vs. EBS plus nasobiliary drain for obstructive jaundice. Front Med (Lausanne) 2022; 9:969225. [PMID: 36186815 PMCID: PMC9515354 DOI: 10.3389/fmed.2022.969225] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Accepted: 08/23/2022] [Indexed: 11/13/2022] Open
Abstract
PurposeBiliary drainage is an important modality for extrahepatic obstructive jaundice both in patients with palliative and resectable. Currently, endoscopic biliary drainage is preferred in clinical practice, including endoscopic nasobiliary drainage (ENBD) and endoscopic biliary stenting (EBS), both of which have their own advantages and disadvantages. The purpose of our study was to compare the safety and efficacy of endoscopic biliary stenting (EBS) only vs. EBS plus nasobiliary drain for obstructive jaundice.MethodsWe consecutively reviewed patients with endoscopic biliary drainage in our institution from November 2014 to March 2021. Combined (ENBD plus stent) and single approach (EBS only) were defined as combined approach and single modality, respectively, and all eligible patients were divided into a combined approach group and a single modality group. We compared combined vs. single modality approaches to investigate whether there were statistical differences in liver chemistries, postoperative adverse events, and stent patency time.ResultsIn 271 patients, a total of 356 times endoscopic biliary drainages were performed. All eligible patients were divided into the combined approach group (n = 74) and the single modality group (n = 271). The combined approach was associated with a lower incidence of postoperative cholangitis and bleeding and greater improvement in liver chemistries, although it was not statistically significant. However, it was superior to the single modality group in terms of hospital stay (12.7 ± 5.2 vs. 14.5 ± 7.9 days, p = 0.020 < 0.05) and stent patency time (8.1 ± 3.9 vs. 4.3±2.7 months, p = 0.001 < 0.05).ConclusionEndoscopic combined (ENBD plus stent) drainage is a more advantageous biliary drainage method that is characterized by more adequate biliary drainage, a lower incidence of postoperative adverse events, and longer effective biliary drainage time.

Abstract
In cholestatic liver diseases, coagulopathy is induced by malabsorption of vitamin K. Supplementation of vitamin K has previously been shown to prevent coagulopathy. In this study, we tested the efficacy of a newly invented micellized vitamin K2 (m-vitK2) in treating coagulopathy, using a rat bile duct ligation (BDL) model. Experiment 1: m-vitK2 (0.3 mg/kg) or m-vitK2 (0.3 mg/kg) mixed with taurocholic acid (TA) (10 mg/body) was orally administrated every day for 7 d from the fourth day after BDL (n=6 for each). Experiment 2: To evaluate absorption, m-vitK2 (0.3 mg/kg) with or without TA (10 mg/body) was orally administered on the fourth day after BDL and compared with the untreated control BDL (n=2 for each). These data were compared with sham-operated (n=6) and untreated control BDL rats (n=6). The m-vitK2 recovered prothrombin time (PT) in Experiment 1 (control 42.7±5.7 s vs. m-vitK2 24.0±9.3 s, p<0.05). Experiment 2 demonstrated that the mixture of m-vitK2 and TA enhanced absorption compared to m-vitK2 alone. Moreover, in Experiment 1, m-vitK2 mixed with TA completely recovered PT (control 42.7±5.7 s vs. m-vitK2+TA 14.9±1.2 s, p<0.01). Micelle sizes decreased with the m-vitK2 and TA treatment (m-vitK2 86.3±5.6 nm vs. m-vitK2+TA 71.9±4.7 nm, p<0.05). Orally administered, newly invented m-vitK2 recovered coagulopathy even under obstructive jaundice. TA decreased the mean micelle size and improved m-vitK2 absorption.

Abstract
Since biliary tract external drainage (BTED) is increasingly used to treat patients with shock, it is necessary to clarify pathophysiological changes following BTED in hemorrhagic shock (HS). The present study aimed to investigate the effect of BTED on farnesoid X receptor (FXR) and Takeda G-protein coupled receptor 5 (TGR-5) expression in HS. A total of 24 Sprague-Dawley rats were randomly allocated to sham, BTED, HS and HS + BTED groups. Rat models of HS were induced by drawing blood from the femoral artery until a mean arterial pressure of 40±5 mmHg was achieved and maintained for 60 min. Rat models of BTED were induced by inserting a catheter into the bile duct. The distal end of the bile duct was ligated, and the catheter was passed through the rat flank to allow external collection of bile. Reverse transcription-quantitative PCR, western blotting and immunohistochemistry were performed to detect changes in expression levels of FXR and TGR-5 in the jejunum, ileum and liver. Expression levels of FXR and TGR-5 increased significantly in jejunum and liver following HS (P<0.05). BTED significantly decreased expression levels of FXR in the liver (P<0.05) and TGR-5 in the jejunum, ileum and liver (P<0.05). In conclusion, expression levels of FXR and TGR-5 increased in HS but BTED decreased expression levels of FXR and TGR-5 in HS.

Abstract
OBJECTIVES People who are critically ill have high rates of endotoxemia that can significantly decrease bile flow and increase bile cytokines, the latter of which might worsen their condition. Bile acids are nutrient-signaling hormones that have a significant impact on gut barrier function and motility, and the gut is considered the origin of systemic inflammation. Therefore, healthy exogenous bile could be a promising gut nutrient for critical illness, so the biomedical role of bile in endotoxemia was investigated in this study. METHODS Twelve rats were injected with lipopolysaccharide (LPS) and randomized into a group with sham operation) and a group with bile external drainage (n = 6 for each group); six rats with sham operation served as the control group. In addition, interleukin-6 (IL-6) knockout mice and macrophages were treated with LPS. RESULTS Compared to the control animals, the group with LPS injection and sham operation had significantly increased levels of gut permeability, gut bacterial translocation, gut mucosal tumor necrosis factor α, IL-6 transcripts, and serum tumor necrosis factor α and IL-6. Compared to group with sham operation and LPS injection, bile external drainage (in LPS-challenged rats) increased gut bacterial translocation by 10 times, and this detrimental effect was associated with prolonged intestinal transit time, increased serum IL-6 concentration, and up-regulated gut mucosal IL-6 transcripts. Moreover, bile selectively inhibited LPS-stimulated macrophages in IL-6 release, which can activate gastrointestinal submucosal neurons to promote motility. Knocking out IL-6 significantly reduced gut bacterial translocation in endotoxemic mice. CONCLUSIONS Bile is a promising gut nutrient that inhibits gut bacterial translocation and promotes gut motility via an IL-6-related pathway in experimental endotoxemia.

Abstract
Background To compare the efficacy of endoscopic nasobiliary drainage (ENBD) and endoscopic biliary stenting (EBS) in preoperative biliary drainage (PBD). Methods ENBD and EBS related literature of patients with malignant biliary obstruction published before September 2019 were collected from PubMed, EMBASE, and Cochrane Library for comparison analysis. Revman 5.3 statistical software was used for analysis. Results Nine studies were used for our comparative study. A total of 1435 patients were included, which consisted of 813 in the ENBD group and 622 in the EBS group. Meta-analysis showed that patients with malignant biliary obstruction who received ENBD had reductions in the rates of preoperative cholangitis (RR = 0.46, 95% CI = 0.34–0.62, P < 0.00001), preoperative pancreatitis (RR = 0.69, 95% CI = 0.50–0.95, P = 0.02), stent dysfunction (RR = 0.58, 95% CI = 0.43–0.80, P = 0.0008), morbidity (RR = 0.77, 95% CI = 0.64–0.93, P = 0.007), and postoperative pancreatic fistula (RR = 0.65, 95% CI = 0.45–0.92, P = 0.02) compared with patients who received EBS. Conclusions The rates of preoperative cholangitis, preoperative pancreatitis, post-operative pancreatic fistula, stent dysfunction, and morbidity of ENBD patients were lower than those of EBS patients. In clinical practice, the physical condition of each patient and their tolerance should be fully considered. ENBD should be given priority. EBS should be replaced if stent dysfunction or intolerance occurs.

Abstract
WHAT IS KNOWN AND OBJECTIVE Vitamin K deficiency is known to cause impaired coagulation. We report a case of marked prolongation of the prothrombin time-international normalized ratio (PT-INR) associated with warfarin and vitamin K deficiency caused by endoscopic nasobiliary drainage (ENBD). CASE PRESENTATION Oral administration of warfarin was initiated in a 67-year-old man after left hemihepatectomy. He developed a biliary fistula after surgery that was treated by ENBD, which resulted in significant prolongation of the PT-INR. WHAT IS NEW AND CONCLUSION The effect of warfarin was enhanced in this patient due to reduced absorption of vitamin K as a result of external biliary drainage.

Abstract
BACKGROUND Although there are many studies on technical outcomes of endoscopic nasobiliary drainage (ENBD), no authors reported on preoperative course of patients undergoing ENBD. The aim of this study was to investigate the course of patients with ENBD during the waiting period. METHODS Patients who underwent resection of perihilar cholangiocarcinoma (PHCC) between January 2013 and September 2017 were retrospectively reviewed. RESULTS During the study period, 191 consecutive patients underwent surgical resection of PHCC after ENBD. Of the study patients, 154 (80.6%) patients were discharged, returned to their home, then re-admitted for surgery. The remaining 37 patients were continuously hospitalized. The number of cholangitis events during the waiting period was 0 in 120 patients, 1 in 59 patients, 2 ≤ in 12 patients. Endoscopic re-intervention was needed in 52 patients. The median length between the first admission and surgery was 37 days (range 12-197 days) in the entire cohort; it was longer in patients with portal vein embolization than in those without (43 vs. 27 days, P < 0.001). CONCLUSIONS In patients undergoing resection of PHCC, ENBD is widely tolerable with relatively low incidence of cholangitis and thus recommended for preoperative biliary drainage.

Abstract
BACKGROUND In patients with resectable perihilar cholangiocarcinoma, biliary drainage is recommended to treat obstructive jaundice and optimise the clinical condition before liver resection. Little evidence exists on the preferred initial method of biliary drainage. We therefore investigated the incidence of severe drainage-related complications of endoscopic biliary drainage or percutaneous transhepatic biliary drainage in patients with potentially resectable perihilar cholangiocarcinoma. METHODS We did a multicentre, randomised controlled trial at four academic centres in the Netherlands. Patients who were aged at least 18 years with potentially resectable perihilar cholangiocarcinoma requiring major liver resection, and biliary obstruction of the future liver remnant (defined as a bilirubin concentration of >50 μmol/L [2·9 mg/dL]), were randomly assigned (1:1) to receive endoscopic biliary drainage or percutaneous transhepatic biliary drainage through the use of computer-generated allocation. Randomisation, done by the trial coordinator, was stratified for previous (attempted) biliary drainage, the extent of bile duct involvement, and enrolling centre. Patients were enrolled by clinicians of the participating centres. The primary outcome was the number of severe complications between randomisation and surgery in the intention-to-treat population. The trial was registered at the Netherlands National Trial Register, number NTR4243. FINDINGS From Sept 26, 2013, to April 29, 2016, 261 patients were screened for participation, and 54 eligible patients were randomly assigned to endoscopic biliary drainage (n=27) or percutaneous transhepatic biliary drainage (n=27). The study was prematurely closed because of higher mortality in the percutaneous transhepatic biliary drainage group (11 [41%] of 27 patients) than in the endoscopic biliary drainage group (three [11%] of 27 patients; relative risk 3·67, 95% CI 1·15-11·69; p=0·03). Three of the 11 deaths among patients in the percutaneous transhepatic biliary drainage group occurred before surgery. The proportion of patients with severe preoperative drainage-related complications was similar between the groups (17 [63%] patients in the percutaneous transhepatic biliary drainage group vs 18 [67%] in the endoscopic biliary drainage group; relative risk 0·94, 95% CI 0·64-1·40). 16 (59%) patients in the percutaneous transhepatic biliary drainage group and ten (37%) patients in the endoscopic biliary drainage group developed preoperative cholangitis (p=0·1). 15 (56%) patients required additional percutaneous transhepatic biliary drainage after endoscopic biliary drainage, whereas only one (4%) patient required endoscopic biliary drainage after percutaneous transhepatic biliary drainage. INTERPRETATION The study was prematurely stopped because of higher all-cause mortality in the percutaneous transhepatic biliary drainage group. Post-drainage complications were similar between groups, but the data should be interpreted with caution because of the small sample size. The results call for further prospective studies and reconsideration of indications and strategy towards biliary drainage in this complex disease. FUNDING Dutch Cancer Foundation.

Abstract
BACKGROUND AND AIM Preoperative cholangitis after preoperative drainage has been reported to increase postoperative complications, particularly pancreatic fistula. We therefore examined the effects of cholangitis after preoperative endoscopic biliary drainage (EBD) on postoperative pancreatic fistula in patients with middle and lower malignant biliary strictures. METHODS The study group comprised 102 patients who underwent EBD among patients who underwent surgery. RESULTS Of the 102 patients, 33 (32%) had postoperative pancreatic fistulas, and 56 (55%) had preoperative cholangitis after preoperative drainage. Analysis of risk factors for preoperative cholangitis showed that a total bilirubin level of 2.9 mg/dL or higher (hazard ratio [HR], 2.95; 95% confidence interval [CI], 1.223-7.130; P = 0.016) and a surgical waiting time of 29 days or longer (HR, 4.23; 95% CI, 1.681-10.637; P = 0.02) were independent risk factors for cholangitis. Patients with preoperative cholangitis had a significantly higher incidence of pancreatic fistula than did patients without preoperative cholangitis (78.8 vs 21.2%; P = 0.001). Patients with biliary cancer had a significantly higher incidence of pancreatic fistula than did those with pancreatic cancer (72.7 vs 27.2%; P = 0.005). Multivariate analysis showed that preoperative cholangitis (HR, 4.8; 95% CI, 1.785-12.992; P = 0.001) and biliary cancer (HR, 3.5; 95% CI, 1.335-8.942; P = 0.006) were significant independent risk factors for postoperative pancreatic fistula. CONCLUSION Prevention of preoperative cholangitis, a risk factor for postoperative pancreatic fistula, is likely to decrease the incidence of postoperative pancreatic fistula.

Abstract
UNLABELLED Operative treatment combined with PBD has been established as a safe management strategy for Klatskin tumors. However, controversy exists regarding the preferred technique for PBD among percutaneous transhepatic biliary drainage (PTBD), endoscopic biliary stenting (EBS), and endoscopic nasobiliary drainage (ENBD). This study aimed to identify the best technique for preoperative biliary drainage (PBD) in Klatskin tumor patients. METHODS This study evaluated 98 Klatskin tumor patients who underwent PBD prior to operation with a curative aim between 2005 and 2012. The PTBD, EBS, and ENBD groups included 43, 42, and 13 patients, respectively. Baseline characteristics, technical success rate, complications of PBD, and surgical outcomes were compared. RESULTS Initial technical success rates (97.3 %, PTBD; 90.2 %, endoscopic methods, including EBS and ENBD) and mean duration until biliary decompression (31.0, PTBD; 28.7, EBS; 35.8 days, ENBD) were not significantly different between the groups. Total frequency of complications did not significantly differ between the EBS group (42.9 %) and the PTBD (27.9 %, p = 0.149) and ENBD (15.4 %, p = 0.072) groups. The ENBD group showed a significantly higher rate of conversion to other methods (76.9 %) than the PTBD (4.7 %, p < 0.0001) and EBS (35.7 %, p = 0.009) groups. CONCLUSIONS PTBD, EBS, and ENBD showed comparable results regarding initial technical success rates, complication rates, and surgical outcomes. As Klatskin tumor patients must undergo PBD prior to 3 weeks before surgery, PTBD and ENBD are uncomfortable and disadvantageous in terms of compliance. EBS was the most suitable method for initial PBD in terms of compliance among Klatskin tumor patients.

Metal versus plastic stents for drainage of malignant biliary obstruction before primary surgical resection. Gastrointest Endosc 2016; 84:814-821.

Abstract
BACKGROUND AND AIMS Preoperative biliary drainage (PBD) with stent placement has been commonly used for patients with malignant biliary obstruction. In PBD, the placement of fully covered self-expandable metal stents (FCSEMSs) may provide better patency duration and a lower incidence of cholangitis compared with plastic stents. We aimed to evaluate which type of stent showed better outcomes in PBD. METHODS In this multicenter, prospective randomized trial, we compared PBD with FCSEMSs versus plastic stents in 86 patients with malignant biliary obstruction between January 2012 and December 2014. Patients with obstructive jaundice were randomly assigned to undergo PBD either with plastic stents or FCSEMS placement. RESULTS Baseline characteristics were not significantly different between the 2 groups. Endoscopic stent placement was technically successful in all patients. Procedure-related adverse events were not significantly different between the 2 groups (plastic vs FCSEMS group; 16.3% vs 16.3%, P = 1.0). Reintervention was required in 16.3% of the plastic stent group and 14.0% of the FCSEMS group (P = .763). The interval to surgery after PBD (plastic vs FCSEMS group; 14.2 ± 8.3 vs 12.3 ± 6.9 days, P = .426) was not significantly different between groups. Surgery-related adverse events occurred in 43.6% of the plastic stent group and 40.0% of the FCSEMS group (P = .755). CONCLUSIONS In patients with resectable malignant biliary obstruction, the outcomes of PBD with plastic stents and FCSEMSs were similar. Considering the cost-effectiveness, PBD with plastic stents may be preferable to FCSEMS placement. (Clinical trial registration number: NCT01789502.).

Risk factors for a high Comprehensive Complication Index score after major hepatectomy for biliary cancer: a study of 229 patients at a single institution. HPB (Oxford) 2016; 18:735-41. [PMID: 27593590 PMCID: PMC5011079 DOI: 10.1016/j.hpb.2016.06.013] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2016] [Revised: 06/15/2016] [Accepted: 06/20/2016] [Indexed: 02/06/2023]
Abstract
BACKGROUND The Comprehensive Complication Index (CCI) is a new tool to evaluate the postoperative condition by calculating the sum of all complications weighted by their severity. The aim of this study was to identify independent risk factors for a high CCI score (≥40) in 229 patients after major hepatectomies with biliary reconstruction for biliary cancers. METHODS The CCI was calculated online via www.assessurgery.com. Independent risk factors were identified by multivariable analysis. RESULTS 57 (25%) patients were classified as having CCI ≥ 40. On multivariable analysis, volume of intraoperative blood loss (≥2.5 L) (p = 0.004) and combined pancreatoduodenectomy (PD) (p = 0.006) were independent risk factors for CCI ≥ 40. A high level of maximum serum total bilirubin was identified as independent risk factors for a high volume of intraoperative blood loss. Liver failure (p = 0.046) was more frequent in patients with combined PD than in those without. DISCUSSION Patients who undergo preoperative external biliary drainage for severe jaundice might have impaired production of coagulation factors. When blood loss during liver transection becomes difficult to control, surgeons should consider various strategies, such as second-stage biliary or pancreatic reconstruction. In patients planned to undergo major hepatectomy with combined PD, preoperative portal vein embolization is mandatory to prevent postoperative liver failure.

Abstract
The lung and kidney are two organs that are easily affected by hemorrhagic shock (HS). We investigated roles of biliary tract external drainage (BTED) in inflammation and edema of the lung and kidney in HS and its relationship with the heme oxygenase-1 (HO-1) pathway. Rat models of HS were induced by drawing blood from the femoral artery until a mean arterial pressure (MAP) of 40 ± 5 mmHg was achieved. A MAP of 40 ± 5 mmHg was maintained for 60 min. Thirty-six Sprague-Dawley rats were randomized to the following groups: sham group; HS group; HS + zinc protoporphyrin IX (ZnPP), a specific HO-1 inhibitor, group; HS + BTED group; HS + BTED + ZnPP group; and HS + BTED + bile infusion (BI) group. HO-1 levels, aquaporin-1 levels, and ratios of dry/wet in the lung and kidney increased markedly after BTED, but tumor necrosis factor-α and myeloperoxidase levels in the lung and kidney decreased significantly after BTED under HS conditions. Under the condition that HO-1 was inhibited by ZnPP, all these effects induced by BTED disappeared in the lung and kidney. These results demonstrated that inflammation and edema of the lung and kidney of HS rats are alleviated by BTED via the HO-1 pathway.

Abstract
AIM: To investigate the effects of biliary tract external drainage (BTED) on intestinal barrier injury in rats with hemorrhagic shock (HS).
METHODS: BTED was performed via cannula insertion into the bile duct of rats. HS was induced by drawing blood from the femoral artery at a rate of 1 mL/min until a mean arterial pressure (MAP) of 40 ± 5 mmHg was achieved. That MAP was maintained for 60 min. A total of 99 Sprague-Dawley rats were randomized into a sham group, an HS group and an HS + BTED group. Nine rats in the sham group were sacrificed 0.5 h after surgery. Nine rats in each of the HS and HS + BTED groups were sacrificed 0.5 h, 1 h, 2 h, 4 h and 6 h after resuscitation. Plasma tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and lipopolysaccharide (LPS) levels were analyzed using enzyme-linked immunosorbent assay. Plasma D-lactate levels were analyzed using colorimetry. The expression levels of occludin and claudin-1 in the ileum were analyzed using Western blot and immunohistochemistry. Histology of the ileum was evaluated by hematoxylin and eosin staining.
RESULTS: Plasma TNF-α levels in the HS + BTED group decreased significantly compared with the HS group at 1 h and 6 h after resuscitation (P < 0.05). Plasma IL-6 levels in the HS + BTED group decreased significantly compared with the HS group at 0.5 h, 1 h and 2 h after resuscitation (P < 0.05). Plasma D-lactate and LPS levels in the HS + BTED group decreased significantly compared with the HS group at 6 h after resuscitation (P < 0.05). The expression levels of occludin in the HS + BTED group increased significantly compared with the HS group at 4 h and 6 h after resuscitation (P < 0.05). The expression levels of claudin-1 in the HS + BTED group increased significantly compared with the HS group at 6 h after resuscitation (P < 0.05). Phenomena of putrescence and desquamation of epithelial cells in the ileal mucosa were attenuated in the HS + BTED group. Ileal histopathologic scores in the HS + BTED group decreased significantly compared with the HS group at 2 h, 4 h and 6 h after resuscitation (P < 0.05).
CONCLUSION: BTED protects against intestinal barrier injury in HS rats.
