World J Gastrointest Oncol 2021; 13:2050-2063. [PMID: 35070041 PMCID: PMC8713328 DOI: 10.4251/wjgo.v13.i12.2050] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2021] [Revised: 04/28/2021] [Accepted: 10/14/2021] [Indexed: 02/06/2023] Open
Abstract
Hilar cholangiocarcinoma (hCCA) is a primary liver tumor associated with a dim prognosis. The role of preoperative and palliative biliary drainage has long been debated. The most common techniques are endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic biliary drainage (PTBD); however, recently developed endoscopic ultrasound-assisted methods are gaining more atention. Selecting the best available method in any specific scenario is crucial, yet sometimes challenging. Thus, this review aimed to discuss the available techniques, indications, perks, pitfalls, and timing-related issues in the management of hCCA. In a preoperative setting, PTBD appears to have some advantages: low risk of postprocedural complications (namely cholangitis) and better priming for surgery. For palliative purposes, we propose ERCP/PTBD depending on the experience of the operators, but also on other factors: the level of bilirubin (if very high, rather PTBD), length of the stenosis and the presence of cholangitis (PTBD), ERCP failure, or altered biliary anatomy.

Abstract
Complications related to percutaneous biliary tract interventions (PBTIs) can range from access site discomfort to life-threatening vascular complications. These complications are relatively uncommon, and most of them are self-limiting. However, major complications for which an increased level of patient care and/or a prolonged hospital stay are required and that may lead to death-albeit rarely-can occur. Some of the most common complications related to PBTI include pain, infection, bile leakage, and catheter blockage. These conditions can be easily recognized by using the patient's clinical history and laboratory examination results. However, the more uncommon complications, such as life-threatening hemobilia, acute pancreatitis, and catheter and stent fractures, may have nonspecific clinical manifestations, and the underlying pathologic condition may be found only when it is being sought specifically. It is important that diagnostic and interventional radiologists be aware of the wide spectrum of PBTI-related complications, as early recognition and treatment may prevent catastrophic situations. In addition, knowledge of the different treatment options is essential for guidance in interventional radiology procedures such as transarterial control of hemobilia, imaging-guided direct percutaneous embolization of pseudoaneurysms, and percutaneous treatment of catheter- and stent-related complications such as fractures. The authors review a wide spectrum of complications associated with PBTI and the percutaneous management of these conditions. They also highlight valuable lessons learned from morbidity and mortality rounds at a high-volume tertiary care center. ©RSNA, 2017.

Abstract
BACKGROUND Percutaneous biliary drainage is an accepted palliative treatment for malignant biliary obstruction. PURPOSE To assess the effect on quality of life (QOL) and bilirubin level reduction in patients with inoperable malignant biliary obstruction treated by unilobar or bilobar percutaneous transhepatic biliary drainage (PTBD). MATERIALS AND METHODS Over a period of 2 years, 49 patients (age range, 22-75 years) of inoperable malignant biliary obstruction were treated by PTBD. Technical and clinical success rates, QOL, patency rates, survival rates, and complications were recorded. Clinical success rates, QOL, and bilirubin reduction were compared in patients treated with complete (n = 21) versus partial (n = 28) liver parenchyma drainage. QOL before and 1 month after biliary drainage were analyzed retrospectively between these two groups. RESULTS Biliary drainage was successful in all 49 patients, with an overall significant reduction of the postintervention bilirubin levels (P < 0.001) resulting in overall clinical success rate of 89.97%. Clinical success rates were similar in patients treated with whole-liver drainage versus partial-liver drainage. Mean serum bilirubin level before PTBD was 19.85 mg/dl and after the procedure at 1 month was 6.02 mg/dl. The mean baseline functional score was 39.35, symptom scale score was 59.55, and global health score was 27.45. At 1 month, mean functional score was 61.25, symptom scale score was 36.0 4, and global health score was 56.33, with overall significant improvement in QOL (<0.001). There was a statistically significant difference in the improvement of the QOL scores (P = 0.002), among patients who achieved clinical success, compared with those patients who did not achieve clinical success at 1 month. We did not find any significant difference in the QOL scores in patients according to the amount of liver drained (unilateral or bilateral drainage), the type of internalization used (ring biliary or stent). Overall, minor and major complications rates were 14.3% and 8.1%, respectively. CONCLUSION Percutaneous biliary drainage provides good palliation of malignant obstructive jaundice. Partial-liver drainage achieved results as good as those after complete liver drainage with significant improvements in QOL and reduction of the bilirubin level.

Abstract
Objective To investigate the outcomes of percutaneous unilateral metallic stent placement in patients with a malignant obstruction of the biliary hila and a contralateral portal vein steno-occlusion. Materials and Methods Sixty patients with a malignant hilar obstruction and unilobar portal vein steno-occlusion caused by tumor invasion or preoperative portal vein embolization were enrolled in this retrospective study from October 2010 to October 2013. All patients were treated with percutaneous placement of a biliary metallic stent, including expanded polytetrafluoroethylene (ePTFE)-covered stents in 27 patients and uncovered stents in 33 patients. Results A total of 70 stents were successfully placed in 60 patients. Procedural-related minor complications, including self-limiting hemobilia (n = 2) and cholangitis (n = 4) occurred in six (10%) patients. Acute cholecystitis occurred in two patients. Successful internal drainage was achieved in 54 (90%) of the 60 patients. According to a Kaplan-Meier analysis, median survival time was 210 days (95% confidence interval [CI], 135-284 days), and median stent patency time was 133 days (95% CI, 94-171 days). No significant difference in stent patency was observed between covered and uncovered stents (p = 0.646). Stent dysfunction occurred in 16 (29.6%) of 54 patients after a mean of 159 days (range, 65-321 days). Conclusion Unilateral placement of ePTFE-covered and uncovered stents in the hepatic lobe with a patent portal vein is a safe and effective method for palliative treatment of patients with a contralateral portal vein steno-occlusion caused by an advanced hilar malignancy or portal vein embolization. No significant difference in stent patency was detected between covered and uncovered metallic stents.

Abstract
INTRODUCTION Placement of self-expanding metallic stents has been a standard palliative treatment for patients with inoperable biliary malignancy, aiming at improving quality of life via a minimally invasive procedure. This study aimed to evaluate the efficacy of percutaneous placement of expanded polytetrafluoroethylene/fluorinated ethylene propylene-covered metallic stents for palliation of inoperable biliary malignancy. MATERIAL AND METHODS Between February 2012 and April 2013, 11 patients with inoperable malignant biliary obstruction were treated with stent implantation. Serum bilirubin and liver enzyme levels were measured before/immediately after stent placement and at one, three, and six months. Patient survival and stent patency were calculated using Kaplan-Meier analysis. RESULTS No migration occurred. Patients showed clinical improvement immediately and one month after stent placement, with a significant reduction in mean serum bilirubin level (p < 0.05). At six months, bilirubin levels were <1.5 mg/dL in all cases. One patient developed acute liver failure four days after stent implantation, leading to death. Survival rates were 90% at three months and 70% at six months. Primary patency rates were 100%, 100%, and 90% at one, three, and six months, respectively. CONCLUSION Percutaneous placement of expanded polytetrafluoroethylene/fluorinated ethylene propylene-covered metallic stents offered an effective palliative therapy for patients with inoperable biliary malignancy.

Abstract
PURPOSE To assess clinical outcomes of metal stent insertion in patients with bilobar bile duct obstruction by malignant tumors. MATERIALS AND METHODS Records of 120 consecutive patients who underwent placement of metallic stents for palliation of malignant bilobar biliary obstruction between 1995 and 2010 were retrospectively reviewed. Single-duct stent insertion was performed in 44 patients with one liver lobe that accounted for more than 70% of total liver volume or only one patent lobar portal vein (group 1). Bilobar stent insertion was performed in 60 patients with approximately equal lobe sizes, patent lobar portal veins, or cholangitis at presentation (group 2). In 16 patients with discontiguous right anterior and posterior segmental ducts (group 3), three stents were deployed in the left lobar and right anterior and posterior segmental ducts. Overall survival, primary patency, and patient morbidity rates following stent insertion were assessed. RESULTS No significant differences in mean overall survival (group 1, 7.3 mo; group 2, 10.3 mo; group 3, 6.5 mo; P = .21) or mean primary stent patency (group 1, 4.2 mo; group 2, 5.9 mo; group 3, 3.5 mo; P = .17) were demonstrated. However, patients in group 3 were significantly more likely to require hospitalizations for cholangitis and additional invasive procedures for recurrent biliary obstruction than patients in groups 1 and 2. CONCLUSIONS Unilobar and bilobar metal stent insertion led to similar outcomes when treatment decision was based on relative liver lobe volumes, lobar portal vein patency, and presence of cholangitis on presentation.

Abstract
BACKGROUND AND AIMS Limited data are available regarding fully covered metal stents in the management of malignant distal biliary strictures. The aim of this study was to evaluate the safety of a fully covered self-expanding metal stent (FCSEMS) with flared ends, in treating malignant biliary strictures. We report our long-term retrospective analysis from 6 centers. METHODS A total of 260 patients (142 males, median age 68 y) underwent endoscopic retrograde cholangiopancreatography with placement of FCSEMS (WallFlex; Boston Scientific, Natick, MA) for the palliation of obstructive jaundice in the setting of pancreatic adenocarcinoma (169), metastatic disease (36), cholangiocarcinoma (23), ampullary cancer (19), or other (13). Patients were evaluated clinically in follow-up and biochemical tests of liver function were obtained. Data were recorded for the following variables: patient survival, duration of stent patency, the need for subsequent biliary intervention, and complications. RESULTS A total of 266 FCSEMS were placed in 260 patients. There was a median survival of 100 days (range, 7 to 531 d). There was a mean follow-up of 134±118 days (range, 4 to 519 d). Biliary decompression was successful in 252 patients (97%). At the end of the study period, 121 were alive with a patent stent, 65 patients died with a patent stent, 40 patients were successfully bridged to surgery, 8 patients had their patent stent removed and had no need for further stenting, and 18 patients were lost to follow-up. Five patients who had a successfully placed FCSEMS were considered a failure due to the following reason: migration (2), cholangitis (1), stent occlusion (1), and removal for management of proximal biliary obstruction (1). Two additional patients experienced migration that did not require FCSEMS removal or replacement. Stent replacement was required in 10 patients, of whom 6 had a second FCSEMS placed. The remaining 4 were in the failure group and underwent replacement with either uncovered stents or plastic stents. Other complications, managed conservatively, included pain (2), postendoscopic retrograde cholangiopancreatography pancreatitis (4), fever (1), retroperitoneal perforation (1), and postsphincterotomy bleeding (1). The mean patency duration was 328 days (SE 19.04). The patency percentage was 83% at 3 months, 63% at 6 months, and 48.5% at 12 months. CONCLUSIONS In the management of malignant distal biliary strictures, the fully covered WallFlex stent has acceptable patency and complication rates. Further long-term prospective data are required to confirm this observation.

Abstract
AIM To investigate the clinical efficiency of percutaneous trans-hepatic bilateral biliary metallic stenting for the management of Bismuth IV malignant obstructive disease. METHODS Our hospital's database was searched for all patients suffering from the inoperable malignant biliary obstruction Bismuth IV, and treated with percutaneous bilateral trans-hepatic placement of self-expandable nitinol stents. The indication for percutaneous stenting was an inoperable, malignant, symptomatic, biliary obstruction. An un-correctable coagulation disorder was the only absolute contra-indication for treatment. Bismuth grading was performed using magnetic resonance cholangiopancreatography. Computed tomography evaluation of the lesion and the dilatation status of the biliary tree was always performed prior to the procedure. All procedures were performed under conscious sedation. A single trans-hepatic track technique was preferred (T-configuration stenting) and a second, contra-lateral trans-hepatic track (Y-configuration stenting) was used only in cases of inability to access the contra-lateral lobe using a single track technique. The study's primary endpoints were clinical success, defined as a decrease in bilirubin levels within 10 d and patient survival rates. Secondary endpoints included peri-procedural complications, primary and secondary patency rates. RESULTS A total of 35 patients (18 female, 51.4%) with a mean age 69 ± 13 years (range 33-88) were included in the study. The procedures were performed between March 2000 and June 2008 and mean time follow-up was 13.5 ± 22.0 mo (range 0-96). The underlying malignant disease was cholangiocarcinoma (n = 10), hepatocellular carcinoma (n = 9), pancreatic carcinoma (n = 5), gastric cancer (n = 2), bile duct tumor (n = 2), colorectal cancer (n = 2), gallbladder carcinoma (n = 2), lung cancer (n = 1), breast cancer (n = 1) or non-Hodgkin lymphoma (n = 1). In all cases, various self-expandable bare metal stents with diameters ranging from 7 to 10 mm were used. Stents were placed in Y-configuration in 24/35 cases (68.6%) using two stents in 12/24 patients and three stents in 12/24 cases (50%). A T-configuration stent placement was performed in 11/35 patients (31.4%), using two stents in 4/11 cases (36.4%) and three stents in 7/11 cases (63.6%). Follow-up was available in all patients (35/35). Patient survival ranged from 0 to 1763 d and the mean survival time was 168 d. Clinical success rate was 77.1% (27/35 cases), and peri-procedural mortality rate was 5.7% (2/35 patients). Biliary re-obstruction due to stent occlusion occurred in 25.7% of the cases (9/35 patients), while in 7/11 (63.6%) one additional percutaneous re-intervention due to stent occlusion resulting in clinical relapse of symptomatology was successfully performed. In the remaining 4/11 patients (36.4%) more than 1 additional reintervention was performed. The median decrease of total serum bilirubin was 60.5% and occurred in 81.8% of the cases (27/33 patients). The median primary and secondary patency was 105 (range 0-719) and 181 d (range 5-1763), respectively. According to the Kaplan-Meyer survival analysis, the estimated survival rate was 73.5%, 47.1% and 26.1% at 1, 6 and 12 mo respectively, while the 8-year survival rate was 4.9%. Major and minor complication rates were 5.7% (2/35 patients) and 17.1% (6/35 patients), respectively. CONCLUSION Percutaneous bilateral biliary stenting is a safe and clinically effective palliative approach in patients suffering from Bismuth IV malignant obstruction.

Abstract
BACKGROUND Unilateral biliary metallic stent placement in the lobe with patent portal vein seemed to be a safe and effective palliative treatment of patients with contralateral portal vein occlusion caused by advanced hilar malignancy, obviating bilateral stent placement in these patients, because the hepatic lobe with portal vein occlusion ceases to produce bile due to interruption of enterohepatic circulation. PURPOSE To investigate the safety and efficacy of percutaneous unilateral expanded polytetrafluoroethylene (ePTFE)-covered stent placement in malignant hilar biliary obstruction with contralateral portal vein occlusion. MATERIAL AND METHODS From February 2008 to March 2011, 24 consecutive patients with malignant hilar biliary obstruction and unilobar portal vein occlusion were enrolled in this prospective study. All patients were treated by percutaneous placement of ePTFE-covered stents. RESULTS Stent deployment was technically successful in all patients. Two (8%) patients experienced minor self-limiting hemobilia. No major complication was noted. Successful internal drainage was achieved in 22 (91.6%) patients. Mean serum bilirubin level, which was 12.5 mg/dl ± 8.4 before drainage, decreased significantly to 2.7 mg/dl ± 3.4, 1 month after stent placement (P < 0.001). Median survival was 191 days (95% CI, 94-288 days) and cumulative stent patency rates at 1, 3, 6, 9, and 12 months were 100%, 95%, 95%, 95%, and 71%, respectively. Two (8%) patients presented with stent occlusion due to sludge incrustation. Aside from two patients who had died within 30 days after stent placement, the other 22 patients demonstrated slight decrease in diameter of undrained lobe and did not experience cholangitis nor jaundice. CONCLUSION Unilateral placement of ePTFE-covered stent in the lobe with patent portal vein seems to be a safe and effective method for palliative treatment of patients with contralateral portal vein occlusion. In addition, ePTFE-covered stent placement can prevent tumor ingrowth without functional occlusion of segmental bile ducts.

Abstract
PURPOSE To assess the technical success, clinical success and complications after 1 month of percutaneous biliary drainage with the placement of several metallic endoprostheses in complex hilar liver tumours. MATERIALS AND METHODS This is a retrospective study, on a homogenous target population of 68 consecutive patients, who underwent multiple percutaneous biliary drainage for complex hilar tumour (Bismuth type II, III and IV) between August 1998 and August 2010. Patients benefiting from previous endoscopic drainage were excluded from the study. The clinical data, biological data, imaging and interventional radiology procedures were studied. RESULTS The rate of success of the technique was 98.5% and the clinical rate of success was 84% after 1 week and 93% after 1 month. The rate of minor and major complications was 25 and 13% respectively. CONCLUSION Multiple percutaneous biliary drainage in complex hilar tumour is a safe and effective first intention procedure.

Abstract
PURPOSE To investigate the technical and clinical safety and efficacy of percutaneous Y-configured covered stent placement in patients with malignant hilar biliary obstruction. MATERIALS AND METHODS This prospective, pilot study enrolled 20 consecutive patients with malignant hilar biliary obstructions from October 2009 to December 2010. All patients were treated by percutaneous transhepatic placement of partially expanded polytetrafluoroethylene (ePTFE)-covered stents in a Y configuration. RESULTS Bilateral Y-configured covered stent deployment was technically successful in all 20 patients. Minor procedure-related complications occurred in four (20%) patients including self-limiting hemobilia in one patient and rapidly resolving cholangitis in three patients. Successful internal drainage was achieved in 18 (90%) of 20 patients. Mean serum bilirubin level, which was 12.6 mg/dL ± 5.1 before drainage, decreased significantly to 2.5 mg/dL ± 4.5 1 month after stent placement (P < .001). Median patient survival and stent patency times were 218 days (95% confidence interval [CI] 112-324 days) and 375 days (95% CI 55-695 days). Seven (35%) patients presented with stent occlusion, in six owing to sludge incrustation and in one owing to tumor overgrowth, and required repeat percutaneous transhepatic biliary drainage (PTBD). Tumor ingrowth, acute cholecystitis, or stent migration was not observed in any patient. CONCLUSIONS Preliminary results suggest that percutaneous palliative treatment of malignant hilar biliary obstruction with Y-configured covered stents is safe and clinically effective in achieving internal biliary drainage. Y-configured, ePTFE-covered stents can also prevent tumor ingrowth without functional occlusion of hepatic segmental bile ducts.

Abstract
OBJECTIVE The purpose of this study was to investigate the outcome of biliary metallic stent placement in patients with contralateral portal vein occlusion caused by advanced hilar malignancy and to compare the outcomes of unilateral and bilateral stent placement. MATERIALS AND METHODS From January 2007 to December 2009, 41 patients with unilobar portal vein occlusion due to advanced hilar malignancy were enrolled in this retrospective study. All patients were treated with percutaneous placement of biliary metallic stents: unilateral stent placement in 23 patients, bilateral stent placement in 18 patients. RESULTS There were no significant differences in technical success (p > 0.999), successful drainage (p > 0.999), early cholangitis (p = 0.734), stent occlusion (p = 0.713), stent patency (p = 0.653), or patient survival (p = 0.493) between the two groups. In the patients who underwent unilateral stent placement, a slight decrease in diameter (mean diameter, 7.2 ± 3 mm before drainage, 6.2 ± 3 mm after stent placement) (p = 0.058) was observed in the intrahepatic bile duct of the undrained lobe with portal vein occlusion. Four of the patients who underwent unilateral stent placement had stent malfunctions, but the other 19 patients did not experience cholangitis or jaundice before death or the end of the study. CONCLUSION Unilateral biliary metallic stent placement in the lobe with a patent portal vein seems to be a safe and effective palliative treatment of patients with contralateral portal vein occlusion caused by advanced hilar malignancy, obviating bilateral stent placement in these patients.

Abstract
BACKGROUND AND AIMS Limited data exist regarding fully-covered, self-expandable metal stents (CSEMS) with anchoring fins for the management of malignant distal biliary strictures. The aim of this study is to evaluate their safety and patency. METHODS Over a period of 2 years, 70 patients (45 males, 66 ± 13 years) underwent endoscopic retrograde cholangiopancreatography (ERCP) with placement of a 10-mm (67 patients) or 8-mm diameter (3 patients) CSEMS for the palliation of distal malignant biliary obstruction (pancreatic [53] or other [17]). Data were collected prospectively for survival and stent patency; complications were evaluated retrospectively. RESULTS After CSEMS placement, 17 patients proceeded to surgery, and 53 patients were deemed unresectable. Mean survival for non-surgical candidates was 180 days (range: 15-1091), and 170 days (range: 9-589) for patients who underwent surgical management. CSEMS were left in place and remained patent for a mean of 163 days (range: 15-1091) in non-surgical candidates, and a mean of 55 days (range: 5-126) in surgical candidates. Complications during placement included wire perforations (4) and proximal deployment requiring repositioning (4), one of which was complicated by a bile leak. Post-procedure complications were observed in 24 cases (34%) and included post-ERCP pancreatitis (8, with 2 of them severe), post-procedure pain (5, with 3 requiring admission), cholecystitis (3), stent occlusion (3), cholangitis (2), proximal migration (1), post-sphincterotomy bleeding (1), and sepsis leading to death (1). CONCLUSION CSEMS appear to provide acceptable short-term patency rates; however, their limited long-term patency and high complication rate might limit their widespread use. Further long-term prospective data are required to confirm this observation.

Abstract
BACKGROUND & AIMS For the treatment of unresectable biliary tract carcinoma with hilar biliary stricture, antitumor therapy and biliary stenting should be addressed in terms of prolonged survival with a good quality of life. However, the endoscopic management of malignant hilar biliary strictures is difficult even for an expert endoscopist. We evaluated the efficacy and safety of the endoscopic deployment of multiple JOSTENT SelfX units in patients with hilar biliary strictures treated with or without chemotherapy. METHODS Between November 2003 and December 2006, endoscopic deployment of multiple JOSTENT SelfX units in hilar biliary strictures by using a partial stent-in-stent procedure was performed on 41 consecutive patients with primary cholangiocarcinoma (n = 34) and gallbladder carcinoma (n = 7) at a gastroenterologic center of Okayama University Hospital. Thirty-three patients were treated with gemcitabine (n = 25) or S-1 (n = 8). RESULTS Metallic stent deployment was successfully accomplished in all cases via only endoscopic procedures. During the follow-up period (mean, 210 days), mean patency time was 150 days, and metallic stent obstruction occurred in 15 cases (37%). Although a repeat intervention was required in all metallic stent obstructed cases, the deployment of the second metallic or plastic stent was completed successfully. The remaining 26 cases (63%) required no interventions. The median overall survival period was only 235 days. However, that of the patients receiving chemotherapy was 392 days. CONCLUSIONS Endoscopic partial stent-in-stent deployment with multiple JOSTENT SelfX prostheses is effective and safe for the treatment of malignant hilar biliary stricture even in patients receiving chemotherapy.

Abstract
We report a case of simultaneous late migration of two ePTFE-FEP covered biliary endoprostheses (Viabil, W.L. Gore, Flagstaff, AZ, USA) that were percutaneously implanted for the treatment of malignant obstructive jaundice. The first Viabil covered stent was placed successfully without any evidence of dislocation or other complication during follow-up. Occlusion of the stent occurred 4 months later and was treated with the placement of a second stent of the same type. Thirteen months later the patient became symptomatic. Percutaneous transhepatic cholangiography (PTC) revealed the presence of a choledocho-duodenal fistula and the disappearance of the two endoprostheses previously implanted. A third metallic stent was then percutaneously positioned through the bilioenteric fistula. The computed tomography scan that followed for the detection of the metallic bodies did not reveal the dislocated metallic stents. Stent migration is a well-known complication of uncovered metallic stents, though Viabil stent migration is assumed to be most unlikely to happen due to the stent's anchoring barbs. Furthermore, the stent had already been tightly fixed by tumor over- and ingrowth, as recognized in previous imaging. This is a very unusual case, describing the disappearance of two metallic foreign bodies encapsulated by tumor.

Abstract
PURPOSE To determine the application and clinical effectiveness of ePTFE/FEP-covered metallic stents for palliation of malignant biliary disease, and to evaluate the efficiency of stent coverage in preventing tumor ingrowth. METHODS During a 3-year period, 36 patients with malignant obstructive jaundice were treated with ePTFE/FEP-covered stents, with or without proximal side holes. The stricture was located in the lower common bile duct (CBD) in 18 cases, the upper CBD in 9, the lower common hepatic duct (CHD) in 6, and the upper CHD in 3 patients. RESULTS Thirty-seven covered stents were percutaneously implanted. The technical success rate was 97%. Reintervention was required in 6 cases. The 30-day mortality rate was 40%, not procedure-related. Mean survival was 128 days. Primary patency rates were 100%, 55.5%, and 25% at 3, 6, and 12 months, respectively, while the assisted patency rate was 100% at 12 months. Stents without side holes had higher primary patency rates compared with those with side holes, where occlusion was always due to tumor ingrowth. Tumor ingrowth did not occur in the completely covered stents. No stent dysfunction due to sludge incrustation was found. Complications were 1 case of arterial laceration that occurred during percutaneous transhepatic cholangiography, and a subcapsular hematoma and 1 case of bile peritonitis, that both occurred during primary stenting. No complications followed the secondary stenting technique. CONCLUSION ePTFE/FEP-covered metallic stents are safe and effective for palliation of malignant biliary disease. The presence of the ePTFE/FEP coating is likely to prevent from tumor ingrowth.

Abstract
BACKGROUND Percutaneous metal stenting is an accepted palliative treatment for malignant biliary obstruction. Nevertheless, factors predicting survival are not known. METHODS Seventy-six patients with inoperable malignant biliary obstruction were treated with percutaneous placement of metallic stents. Twenty patients had non-hilar lesions. Fifty-six patients had hilar lesions classified as Bismuth type I (n = 15 patients), type II (n = 26), type III (n = 12), or type IV (n = 3 patients). Technical and clinical success rates, complications, and long-term outcome were recorded. Clinical success rates, patency, and survival rates were compared in patients treated with complete (n = 41) versus partial (n = 35) liver parenchyma drainage. Survival was calculated and analyzed for potential predictors such as the tumor type, the extent of the disease, the level of obstruction, and the post-intervention bilirubin levels. RESULTS Stenting was technically successful in all patients (unilateral drainage in 70 patients, bilateral drainage in 6 patients) with an overall significant reduction of the post-intervention bilirubin levels (p < 0.001), resulting in a clinical success rate of 97.3%. Clinical success rates were similar in patients treated with whole-liver drainage versus partial liver drainage. Minor and major complications occurred in 8% and 15% of patients, respectively. Mean overall primary stent patency was 120 days, while the restenosis rate was 12%. Mean overall secondary stent patency was 242.2 days. Patency rates were similar in patients with complete versus partial liver drainage. Mean overall survival was 142.3 days. Survival was similar in the complete and partial drainage groups. The post-intervention serum bilirubin level was an independent predictor of survival (p < 0.001). A cut-off point in post-stenting bilirubin levels of 4 mg/dl dichotomized patients with good versus poor prognosis. Patient age and Bismuth IV lesions were also independent predictors of survival. CONCLUSIONS Percutaneous metallic biliary stenting provides good palliation of malignant jaundice. Partial liver drainage achieved results as good as those after complete liver drainage. A serum bilirubin level of less than 4 mg/dl after stenting is the most important independent predictor of survival, while increasing age and Bismuth IV lesions represent dismal prognostic factors.

Abstract
The efficacy of the "one-step" technique using two different metallic stents (Wallstent and Ultraflex) and associated rate of complications was studied in 87 patients with jaundice secondary to malignant biliary obstruction, with bilirubin level less than 15 mg/dl and Bismuth type 1 or 2 strictures. The study group, composed of 40 men and 47 women with a mean age of 59.4 years (range 37-81 years), was treated with a "one-step" percutaneous transhepatic implantation of self-expanding stents. The cause of the obstruction was pancreatic carcinoma in 38 patients (44%), lymph node metastasis in 20 patients (23%), gallbladder carcinoma in 13 patients (15%), cholangiocarcinoma in 12 patients (14%) and ampullary carcinoma in four patients (5%). A significant reduction in jaundice was obtained in all but one patient, with a drop of total serum bilirubin level from a mean of 13.7 mg/dl to 4.3 mg/dl within the first 4 days. The mean postprocedural hospitalization period was 5.4 days in the Wallstent group and 6.4 days in the Ultraflex group. Mean survival rate was 7.8 months (Wallstent group) and 7.1 months (Ultraflex group). The use of both stents did not reveal any significant difference in parameters tested. The implantation of these self-expandable stents in one session, in selected patients, is clinically effective, devoid of important complications and cost-effective due to the reduction in hospitalization.

Abstract
PURPOSE To evaluate the necessity of draining more than one hepatic duct in malignant hilar obstructions. MATERIALS AND METHODS Two hundred seventeen self-expandable uncovered metallic stents (144 biliary Wallstents and 73 Memotherm nitinol stents) were placed percutaneously in 138 patients with unresectable malignant hilar obstructions. The patients included 76 men and 62 women, with a median age of 76 years (range, 43-82 years). Single-duct drainage was achieved in 74 patients (54%) by placing one stent (n = 59) or by placing an additional stent inserted telescopically through the first one (n = 15) to achieve an adequate stent length for long strictures (group 1). In 64 patients (46%), to maintain two-duct drainage, two stents were inserted through dual transhepatic tracts in a "Y" configuration (n = 41; group 2Y) or a single transhepatic tract in a "T" configuration (n = 23; group 2T). RESULTS The overall technical success rate was 100%, and early clinical response was obtained in 89% of patients. The overall rate of major complications was 5.7% and did not show a statistically significant difference among groups 1, 2Y, and 2T in Bismuth type II, III, and IV obstructions. The patency rate was not statistically significant among groups 1, 2Y, and 2T in Bismuth type II and III obstructions (P >.05). However, in Bismuth type IV obstructions, the patency rate was significantly higher in group 2Y (P =.03; Kruskal-Wallis test). CONCLUSION There is no need to place more than one stent in Bismuth type I, II, and III hilar obstructions. In Bismuth type IV obstructions, deployment of two parallel stents through dual transhepatic tracts should be performed.

Abstract
Interventional radiologists have an important role in the management of patients with malignant biliary obstruction. This article describes the techniques for percutaneous biliary drainage, insertion of biliary endoprostheses, and the management of occluded biliary endoprostheses. Most procedures are performed by using fluoroscopic guidance alone. Ultrasound is also a useful modality for guiding biliary drainage, particularly drainage of the left biliary ducts. Patients should be treated by internal drainage if possible. Metallic endoprostheses can be inserted at the time of the initial biliary drainage procedure. Plastic tubes should be inserted a few days after biliary drainage because of their relatively large size compared with metallic stents. Occluded plastic stents should be replaced. Blocked metallic stents should be treated either by placement of additional overlapping metallic stents or by placement of plastic stents within the metallic stent lumen.

Abstract
Thirty-five patients with malignant obstructive jaundice received palliative treatment using percutaneous self-expandable metallic stents. Cholangiocarcinoma was the most frequent cause of the biliary obstruction. In more than 50% of cases, the stricture was located in the hilum. Adequate biliary drainage was achieved in 97% of cases. Median survival was 182 days, and 11% of patients died within 30 days. Early complications occurred in 31% of patients, and 25% of patients showed recurrent jaundice after an average of 180 days. Percutaneous self-expandable metallic stents are an efficient means of palliatively treating malignant biliary strictures, particularly high biliary obstructions.
