Fully covered versus partially covered self-expandable metal stents for palliation of distal malignant biliary obstruction: a systematic review and meta-analysis. Gastrointest Endosc 2024; 99:314-322.e19. [PMID: 37813199 DOI: 10.1016/j.gie.2023.10.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 08/28/2023] [Accepted: 10/04/2023] [Indexed: 10/11/2023]
Abstract
BACKGROUND AND AIMS Self-expandable metal stents (SEMSs) are standardly used for distal malignant biliary obstruction (dMBO). Although data suggest that covered versus uncovered SEMSs increase the time to recurrent biliary obstruction (TRBO), no data are available for fully covered (FC) versus partially covered (PC) designs. METHODS PubMed, Scopus, and Cochrane databases were screened up to January 2023 for studies concerning dMBO treated by an FC- or PC-SEMS and describing adverse events (AEs), recurrences, or TRBO for specific design subpopulations. Pooled proportions or means were calculated using a random-effects model. Several subanalyses were preplanned, including a subanalysis restricted to prospective studies and unresectable diseases. Heterogeneity and publication bias were explored. Standardized differences (d-values) were calculated between groups. RESULTS From 1290 records, 62 studies (3327 using FC-SEMSs and 2322 using PC-SEMSs) were included. FC- versus PC-SEMSs showed negligible differences in the rate of total AEs (12% vs 9.9%) and all specific AEs, including cholecystitis (2.5% vs 2.6%). In a subanalysis restricted to prospective studies and unresectable diseases, the rate of RBO was comparable between FC-SEMSs (27.3% [95% confidence interval {CI}, 23.7-31.2], I2 = 35.34%) and PC-SEMSs (25.3% [95% CI, 20.2-30.7], I2 = 85.09%), despite small differences (d-values between .186 and .216) in the rate of ingrowth (.5% vs 2.9%) favoring FC-SEMSs and migration (9.8% vs 4.3%) favoring PC-SEMSs. TRBO was shorter for FC-SEMSs (238 days [95% CI, 191-286], I2 = 63.1%) versus PC-SEMSs (369 days [95% CI, 290-449], I2 = 71.9%; d-value = .116). CONCLUSIONS Despite considerable heterogeneity and small standardized differences, PC-SEMSs consistently exhibited longer TRBO than FC-SEMSs across analyses, without any other differences in AE rates, potentially proposing PC-SEMSs as the standard comparator and TRBO as the primary outcome for future randomized studies on dMBO.

Abstract
Abstract
Background and study aims For distal malignant biliary obstruction, self-expandable metallic stents (SEMSs) have a larger inner diameter compared to plastic stents, which prolongs time to recurrent biliary obstruction (TRBO), although stent-related complications are still a problem. This study aimed to compare the outcomes between using 10– and 6-mm-diameter fully-covered SEMS (FCSEMS) for distal malignant biliary obstruction.
Patients and methods This single-center, retrospective study included patients with 10-mm or 6-mm-diameter FCSEMS to treat distal malignant biliary obstruction. Clinical success, stent-related adverse events (AEs), cumulative incidence of RBO, factors involved in stent-related AEs, and factors involved in RBO were evaluated.
Results There were 243 eligible cases between October 2017 and December 2021. The cumulative incidence of RBO did not differ significantly between the 10-mm and 6-mm groups. Stent-related AEs occurred in 31.6 % and 11.4 % of patients between the 10-mm and 6-mm groups, respectively (P < 0.01). Pancreatitis occurred in 10.5 % and 3.6 % (P = 0.04) and cholecystitis occurred in 11.8 % and 3.0 % of patients (P = 0.03) in the 10-mm and 6-mm groups, respectively. In multivariate analysis, the 6-mm stent was extracted as a factor linked to a reduced risk of AEs, but not as a risk factor of RBO.
Conclusions The 6-mm-diameter FCSEMS for distal malignant biliary obstruction is a well-balanced stent with a cumulative incidence of RBO compatible to that of the 10-mm-diameter FCSEMS and fewer stent-related AEs.

Abstract
BACKGROUND AND AIMS Patients with distal malignant biliary obstruction (MBO) and cystic duct orifice tumoral involvement have an increased risk for the development of acute cholecystitis after self-expandable metallic stent (SEMS) placement. We aimed to determine whether primary EUS-guided gallbladder drainage prevents acute cholecystitis in these patients. METHODS This was a single-center, randomized control trial in patients with distal MBO enrolled from July 2018 to July 2020. Patients were randomized into 2 groups: an interventional group treated with conventional ERCP biliary drainage with SEMS placement and subsequent primary EUS-guided gallbladder drainage (EUS-GBD) and a control group treated with conventional biliary drainage alone. The primary outcome of the study was the occurrence of post-treatment acute cholecystitis, assessed for ≤12 months or until death. The secondary outcomes were hospitalization length and median survival time. RESULTS Forty-four patients were included in the study: 22 in each group. Five patients in the control group (22.7%) and none in the intervention group experienced acute cholecystitis. The median hospitalization time was significantly lower in the interventional group than in the control group (2 days vs 1 day, P = .017). There was no difference in the observed median survival rates in the primary EUS-GBD group (2.9 months) and the control group (2.8 months) (P = .580). CONCLUSION In this single-center study of patients with unresectable MBO and occlusion of the cystic duct orifice, prophylactic EUS-GBD demonstrated a reduced incidence of acute cholecystitis.

Abstract
BACKGROUND/AIMS Patients with acute cholecystitis (AC) after metallic stent (MS) placement for malignant biliary obstruction (MBO) have a high surgical risk. We performed percutaneous transhepatic gallbladder aspiration (PTGBA) as the first treatment for AC. We aimed to identify the risk factors for AC after MS placement and the poor response factors of PTGBA. METHODS We enrolled 401 patients who underwent MS placement for MBO between April 2011 and March 2020. The incidence of AC was 10.7%. Of these 43 patients, 37 underwent PTGBA as the first treatment. The patients' responses to PTGBA were divided into good and poor response groups. RESULTS There were 20 patients in good response group and 17 patients in poor response group. Risk factors for cholecystitis after MS placement included cystic duct obstruction (p<0.001) and covered MS (p<0.001). Cystic duct obstruction (p=0.003) and uncovered MS (p=0.011) demonstrated significantly poor responses to PTGBA. Cystic duct obstruction is a risk factor for cholecystitis and poor response factor for PTGBA, whereas covered MS is a risk factor for cholecystitis and an uncovered MS is a poor response factor of PTGBA for cholecystitis. CONCLUSION The onset and poor response factors of AC after MS placement were different between covered and uncovered MS. PTGBA can be a viable option for AC after MS placement, especially in patients with covered MS.

Abstract
BACKGROUND Considering the limitations in both uncovered self-expandable metallic stents (USEMS) and covered self-expandable metallic stents (CSEMS), it is difficult to make a general recommendation for their application in percutaneous decompression of malignant biliary obstruction (MBO). PURPOSE To compare percutaneous transhepatic CSEMSs versus USEMSs for the palliative treatment of MBO in terms of technical success, clinical success, stent patency, patient survival, complications, and stent dysfunction. MATERIAL AND METHODS This prospective randomized study included 66 patients with unresectable MBO. CSEMSs were inserted in 31 patients (26 men, 5 women; mean age = 63.8 ± 7.96 years) and USEMSs were inserted in 35 patients (26 men, 9 women; mean age = 62.3 ± 11.7 years). RESULTS Mean primary stent patency duration was 138 ± 92.7 days in CSEMSs versus 150 ± 77.9 days in USEMSs (P = 0.578). Tumor overgrowth occurred exclusively in one patient with CSEMS (P = 0.470) and tumor ingrowth exclusively in two patients with USEMS (P = 0.494). Stent migration occurred in two patients with CSEMSs versus one patient with USEMSs (P = 0.579). Hemobilia occurred in five patients with CSEMSs versus three patients with USEMSs while bile leakage occurred in one patient in each group despite the larger introducer sheath caliber with CSEMSs (9 F vs. 6-7 F). There was no significant difference regarding patient survival (P = 0.969). CONCLUSION In our cohort of patients with rather poor life expectancy, there was no significant difference between covered and uncovered stents for the palliative treatment of MBO. However, considering the higher cost of CSEMs and the larger introducer diameter necessary for their placement, USEMSs can be preferred.

Abstract
Background and Aim A self-expandable metallic stent (SEMS) is commonly used for biliary stricture caused by pancreatic cancer. Covered SEMS may obstruct the cystic duct, causing acute cholecystitis. This study aimed to determine the outcomes of using a half-covered SEMS with an offset covered portion for preventing cystic duct obstruction. Methods Among 80 patients with half-covered SEMS placement for the treatment of pancreatic cancer-induced distal biliary stricture, 74 were followed up. The half-covered SEMS has a total length of 6 or 7 cm, and the offset covered part was 0.5-4.5 or 0.5-5.5 cm, respectively. Intraductal ultrasonography (IDUS) and endoscopic nasobiliary drainage (ENBD) were performed during the initial endoscopic retrograde cholangiopancreatography (ERCP). IDUS findings and ENBD tube cholangiogram confirmed the cystic duct confluence. SEMS placement was performed on the second ERCP or several weeks after the initial tube stent placement. Results Half-covered SEMS placement was successful in all patients. However, four (5.4%) patients exhibited early complications, including acute cholecystitis in one patient and stent displacement in another. Over 30 days, cholangitis, tumor growth, and stent displacement occurred in nine (11.3%), five (6.3%), and two (2.5%) patients, respectively. The median stent patency was 71.1 weeks, and the median overall survival in patients with and without chemotherapy was 31.8 and 12.2 weeks, respectively. Conclusions With confirmation of the cystic duct confluence, half-covered SEMS placement may become a treatment option for distal biliary stricture caused by pancreatic cancer to prevent acute cholecystitis. Half-covered SEMS patency was comparable with that of covered SEMS.

Abstract
BACKGROUND For decades, endoscopic retrograde cholangiopancreatography (ERCP) has been widely performed as a diagnostic and therapeutic procedure for biliary and pancreatic diseases. Complications of ERCP include pancreatitis, hemorrhage, perforation, cholangitis, and cholecystitis. There are few studies that focus on the incidence of post-ERCP cholecystitis and its potential risk factors. METHODS A retrospective single-center study was performed in 1345 ERCP procedures after excluding patients with current cholecystitis or post-cholecystectomy between January 2009 and December 2011. Potential risk factors for post-ERCP acute cholecystitis, including age, gender, biochemistry, imaging data, procedures such as endoscopic sphincterotomy (EPT), or endoscopic retrograde biliary drainage (ERBD), were obtained and analyzed by multivariate logistic regression analysis. RESULTS Cholecystitis developed after 13 (0.96%) of the 1345 ERCP procedures. Univariate and multivariate logistic regression analyses showed that cystic duct stones (odds ratio [OR] = 198.26; 95% CI, 5.12-7835.44) and ERBD (OR = 37.58; 95% CI, 3.25-445.56) were important potential risk factors for post-ERCP cholecystitis. The percentage of ERBD procedures and cystic duct stones in patients with post-ERCP cholecystitis was 76.9% and 39.8%, respectively. The 13 patients with post-ERCP cholecystitis all received antibiotics, and four of them also received percutaneous gallbladder drainage. All patients recovered without significant clinical event or mortality. CONCLUSION The incidence of post-ERCP cholecystitis was 0.96% in the 1345 ERCP procedures performed. Cyst duct stones and ERBD were found to be risk factors for post-ERCP cholecystitis.

Abstract
BACKGROUND Endoscopic transpapillary gallbladder drainage (ETGBD) for acute cholecystitis (AC) after self-expandable metal stent (SEMS) placement is technically challenging and there are no reports about its outcome in a several cases. This study aims to assess the outcomes of ETGBD for AC after SEMS placement. METHODS Between April 2011 and April 2019, 314 patients underwent SEMS placement for biliary stricture. Among them, 12 of 21 patients who developed AC after SEMS placement underwent ETGBD. In general, ETGBD was performed after SEMS removal in cases in which a covered SEMS was previously placed or with the SEMS kept in place in cases in which an uncovered SEMS was previously placed. When the orifice of the cystic duct overlapped the uncovered SEMS, ETGBD was performed through the mesh of the SEMS. RESULTS Among the 12 patients who underwent ETGBD, the previously placed SEMS was in the distal (n=8) or perihilar (n=4) bile duct. The type of SEMS placed in the distal bile duct was covered in 7 (fully covered: 6, partially covered: 1) and uncovered in 1, whereas that in the perihilar bile duct was uncovered for all. The technical success rate of ETGBD was 83.3% (10/12), and that according to the previous SEMS placement site was 75.0% (6/8) for the distal bile duct and 100% (4/4) for the perihilar bile duct. In the technically successful, the clinical success rate for AC was 90.0% (9/10). The rate of adverse event was 16.7% (2/12) (stent kink: 1, tube self-removal: 1). CONCLUSIONS ETGBD can have relatively good outcomes for AC after SEMS placement.

Abstract
Biliary and pancreatic cancers occur silently in the initial stage and become unresectable within a short time. When these diseases become symptomatic, biliary obstruction, either with or without infection, occurs frequently due to the anatomy associated with these cancers. The endoscopic management of these patients has changed, both with time and with improvements in medical devices. In this review, we present updated and integrated concepts for the endoscopic management of malignant biliary stricture. Endoscopic biliary drainage had been indicated in malignant biliary obstruction, but the concept of endoscopic management has changed with time. Although routine endoscopic stenting should not be performed in resectable malignant distal biliary obstruction (MDBO) patients, endoscopic biliary drainage is the treatment of choice for palliation in unresectable MDBO patients. Self-expanding metal stents (SEMS) have better stent patency and lower costs compared with plastic stents (PS). For malignant hilum obstruction, PS and uncovered SEMS yield similar short-term outcomes, while a covered stent is not usually used due to a potential unintentional obstruction of contralateral ducts.

Abstract
Flexible digestive endoscopes are used for the management of various conditions with hundreds of thousands of therapeutic procedures performed worldwide each year. Duodenoscopes are indispensable tools for the delivery of minimally invasive vital care of numerous pancreaticobiliary disorders. Despite the fact that nosocomial infections after endoscopic retrograde cholangiopancreatography (ERCP) have always been among the most frequently cited postprocedural complications, recent emergence of duodenoscope-transmitted multiple drug-resistant bacterial infections has led to intense research and debate yet with no clearly delineated solution. Duodenoscope-transmitted nosocomial infections have become one of the most visible topics in the recent literature. Hundreds of high-impact articles have therefore been published in the last decade. This review article discusses how such infections were seen in the past and what is the current situation in both research and practice and thus tries to solve some of the unanswered questions for the future. With the persistence of nosocomial infections despite strict adherence to both manufacturer-issued reprocessing protocols and international guidelines and regulations, an urgent and proper microbiologically driven common action is needed for controlling such nosocomial worldwide threat.

Abstract
Benign and malignant biliary strictures are common indications for endoscopic retrograde cholangiopancreatography. Diagnosis involves high-quality cross-sectional imaging and cholangiography with various endoscopic sampling techniques. Treatment options include placement of plastic biliary stents and self-expanding metal stents, which differ in patency duration and cost effectiveness. Whether the etiology is benign or malignant, a multidisciplinary strategy should be implemented. This article will discuss general principles of biliary stenting in both benign and malignant conditions.

Endoscopic Sphincterotomy before Fully Covered Metal Stent Placement Is Not Required for Distal Malignant Biliary Stricture due to a Pancreatic Head Tumor. Gastroenterol Res Pract 2019; 2019:9675347. [PMID: 30774655 PMCID: PMC6350600 DOI: 10.1155/2019/9675347] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/11/2018] [Revised: 11/15/2018] [Accepted: 12/04/2018] [Indexed: 02/03/2023] Open
Abstract
Background/Aims Endoscopic sphincterotomy (EST) is often performed before fully covered self-expandable metal stent (FCSEMS) placement in order to prevent pancreatitis. However, it is not clear whether EST prevents pancreatitis or affects other adverse events (AEs). This study is conducted to evaluate the necessity of EST before FCSEMS placement for distal malignant biliary strictures due to a pancreatic head tumor. Methods This study included 68 patients who underwent FCSEMS placement for distal malignant biliary stricture due to a pancreatic head tumor. Treatment outcomes and AEs were retrospectively compared between 32 patients with EST before FCSEMS placement (EST group) and 36 patients without EST (non-EST group). Results The success rates of drainage for the EST and non-EST groups were 100% and 97.2%, respectively (P = 0.95). The incidence of pancreatitis in the EST and non-EST groups was 3.1% and 0%, respectively (P = 0.95). The incidence of hyperamylasemia in the EST and non-EST groups was 12.5% and 13.9%, respectively (P = 0.85). The incidence of all AEs in the EST and non-EST groups was 15.6% (pancreatitis: 1, cholecystitis: 2, and stent migration: 2) and 13.9% (cholecystitis: 3, stent migration: 2), respectively (P = 0.89). Conclusions EST before FCSEMS placement for distal malignant biliary stricture due to a pancreatic head tumor does not affect the successful drainage and incidence of adverse events. The necessity of EST to prevent pancreatitis before FCSEMS placement was deemed low.

Abstract
BACKGROUND Both fully covered (FC) and partially covered (PC) self-expandable metal stents (SEMSs) are now commercially available for distal malignant biliary obstruction (MBO). While FCSEMS can be easily removed at the time of re-interventions, it is theoretically prone to migration. However, few comparative data between FC and PC SEMSs have been reported. AIMS The aim of this study was to compare clinical outcomes of FCSEMS with those of PCSEMS. METHODS This was a multicenter, prospective study of FCSEMS for unresectable distal MBO with a historical control of PCSEMS, which was previously reported as the WATCH study. The primary outcome was recurrent biliary obstruction (RBO), and secondary outcomes were stent migration, stent removal, stent-related adverse events, and survival. RESULTS A total of 151 cases with unresectable distal MBO undergoing FCSEMS placement were enrolled and compared with a historical cohort of 141 cases undergoing PCSEMS placement. No significant differences were found in the rate of RBO (29 vs. 33%; P = 0.451), time to RBO (318 vs. 373 days; P = 0.382), and survival (229 vs. 196 days; P = 0.177) between FCSEMS and PCSEMS. The rate of stent migration also did not differ significantly between the two groups (14 vs. 8%; P = 0.113). The removal of FCSEMSs was successful in all 24 attempted cases (100%). CONCLUSIONS FCSEMSs appeared comparable to PCSEMSs in terms of RBO without a significant increase in stent migration rate in patients with unresectable distal MBO.

Abstract
BACKGROUND AND AIM Cholecystitis is a major complication after self-expandable metallic stent (SEMS) placement for malignant biliary obstruction. Ischemia is one of the risk factors for cholecystitis, but little is known about the influence of tumor invasion to the feeding artery of the gallbladder on the onset of cholecystitis after SEMS placement. The aim of the present study was to identify risk factors for cholecystitis after SEMS placement. METHODS Incidence and nine predictive factors of cholecystitis were retrospectively evaluated in 107 patients who underwent SEMS placement for unresectable distal malignant biliary obstruction at Kyoto University Hospital and Otsu Red Cross Hospital between January 2012 and June 2016. RESULTS Cholecystitis occurred in 13 of 107 patients (12.1%) after SEMS placement during the median follow-up period of 262 days. Univariate analyses showed that tumor invasion to the feeding artery of the gallbladder and tumor involvement to the orifice of the cystic duct were significant predictors of cholecystitis (P = 0.001 and P < 0.001). Multivariate analysis confirmed that these two factors were significant and independent risks for cholecystitis with odds ratios of 22.13 (95% CI, 3.57-137.18; P = 0.001) and 25.26 (95% CI, 4.12-154.98; P < 0.001), respectively. CONCLUSIONS This study showed for the first time that tumor invasion to the feeding artery of the gallbladder as well as tumor involvement to the orifice of the cystic duct are independent risk factors for cholecystitis after SEMS placement.

Abstract
OPINION STATEMENT Pancreas cancer is a fourth-leading cause of cancer death in the USA and its incidence is rising as the population is aging. The majority of patients present at an advanced stage due to the silent nature of the disease and treatment have focused more on palliation than curative intent. Gastroenterologists have become integral in the multidisciplinary care of these patients with a focus on providing endoscopic palliation of pancreas cancer. The three most common areas that gastroenterologists palliate endoscopically are biliary obstruction, cancer-related pain, and gastric outlet obstruction. To palliate biliary obstruction, the procedure of choice is to perform endoscopic retrograde cholangiopancreatography (ERCP) with biliary stent placement. We tend to place covered self-expandable metal stents (SEMS) due to their longer patency and removability unless the patient has resectable disease. Pancreas cancer pain is a result of tumor infiltration of the celiac plexus and can be severe and poorly responsive to narcotics. To improve pain control, neurolysis of the celiac plexus has been performed for decades. Since 1996, neurolysis of the celiac area has been performed endoscopically by Endoscopic Ultrasound-Guided Celiac Plexus Neurolysis. This has proven to be as safe and effective as traditional non-endoscopic methods and has allowed the patients to decrease their narcotic use and improve their pain control. This should be done early on in the course of the disease to have maximal effect. Gastric outlet obstruction (GOO) occurs in approximately 15-20% of patients with pancreas cancer. Endoscopic palliation of GOO can be performed by placing uncovered metal enteral stents across the obstruction. This procedure has proven to be very effective in patients who have a short life expectancy (less than two to 6 months) while surgical bypass should be considered for patients with longer life expectancies because it offers better long-term symptom relief. This chapter will review the current literature, latest advancements, and optimal techniques for endoscopic palliation of pancreatic cancer.

Abstract
Background/Aims The covered self-expandable metal stent (CMS) was developed to prevent tumor ingrowth-induced stent occlusion during the treatment of malignant biliary obstruction. However, complications such as cholecystitis, pancreatitis, and stent migration can occur after the endoscopic insertion of CMSs. The aim of the present study was to assess the efficacy and safety of a double-layered CMS (DCMS) for the management of malignant bile duct obstruction. Methods DCMSs were endoscopically introduced into 59 patients with unresectable malignant extrahepatic biliary obstruction at four tertiary referral centers, and the patient medical records were retrospectively reviewed. Results Both the technical and functional success rates were 100%. Procedure-related complications including pancreatitis, cholangitis, stent migration, and liver abscess occurred in five patients (8.5%). The median follow-up period was 265 days (range, 31 to 752 days). Cumulative stent patency rates were 68.2% and 40.8% at 6 and 12 months, respectively. At the final follow-up, the rate of stent occlusion was 33.9% (20/59), and the median stent patency period was 276 days (range, 2 to 706 days). Conclusions The clinical outcomes of DCMSs were comparable to the outcomes previously reported for CMSs with respect to stent patency period and complication rates.

Abstract
AIM To compare the efficacy of using covered self-expandable metal stents (CSEMSs) and uncovered self-expandable metal stents (UCSEMSs) to treat objective jaundice caused by an unresectable malignant tumor. METHODS We performed a comprehensive electronic search from 1980 to May 2015. All randomized controlled trials comparing the use of CSEMSs and UCSEMSs to treat malignant distal biliary obstruction were included. RESULTS The analysis included 1417 patients enrolled in 14 trials. We did not detect significant differences between the UCSEMS group and the CSEMS group in terms of cumulative stent patency (hazard ratio (HR) 0.93, 95% confidence interval (CI) 0.19-4.53; p = 0.93, I2 = 0%), patient survival (HR 0.77, 95% CI 0.05-10.87; p = 0.85, I2 = 0%), overall stent dysfunction (relative ratio (RR) 0.85, M-H, random, 95% CI 0.57-1.25; p = 0.83, I2 = 63%), the overall complication rate (RR 1.26, M-H, fixed, 95% CI 0.94-1.68; p = 0.12, I2 = 0%) or the change in serum bilirubin (weighted mean difference (WMD) -0.13, IV fixed, 95% CI 0.56-0.3; p = 0.55, I2 = 0%). However, we did detect a significant difference in the main causes of stent dysfunction between the two groups. In particular, the CSEMS group exhibited a lower rate of tumor ingrowth (RR 0.25, M-H, random, 95% CI 0.12-0.52; p = 0.002, I2 = 40%) but a higher rate of tumor overgrowth (RR 1.76, M-H, fixed, 95% CI 1.03-3.02; p = 0.04, I2 = 0%). Patients with CSEMSs also exhibited a higher migration rate (RR 9.33, M-H, fixed, 95% CI 2.54-34.24; p = 0.008, I2 = 0%) and a higher rate of sludge formation (RR 2.47, M-H, fixed, 95% CI 1.36-4.50; p = 0.003, I2 = 0%). CONCLUSIONS Our meta-analysis indicates that there is no significant difference in primary stent patency and stent dysfunction between CSEMSs and UCSEMSs during the period from primary stent insertion to primary stent dysfunction or patient death. However, when taking further management for occluded stents into consideration, CSEMSs is a better choice for patients with malignant biliary obstruction due to their removability.

Abstract
PURPOSE Presence of biliary stent may alter biliary dynamics, which may change the results of cholescintigraphy. We assessed the frequency of gallbladder (GB) nonvisualization and its specificity for acute cholecystitis (AC) in patients with stent. PATIENTS AND METHODS Of 44 with stent who had cholescintigraphy, 22 were excluded because of prior cholecystectomy or little to no radiotracer excretion from the liver precluding assessment of GB filling. Cholescintigraphy performed on the remaining 22 with stent and their medical records were reviewed. We also assessed the frequency of GB nonvisualization in the comparison group of 1044 without stent who had cholescintigraphy for evaluation of AC. RESULTS Gallbladder was not visualized in 21 (96%) of 22 with stent, 10 of whom did not have high clinical suspicion of AC. Gallbladder was visualized in only 1 patient on delayed imaging at 4 hours. Four had cholecystectomy, 3 had chronic cholecystitis and 1 AC superimposed on chronic cholecystitis. The highest possible specificity derived from our data assuming an extreme hypothetical scenario was only 25% with the true specificity likely being 7% or lower. In contrast to patients with stents, only 188 (18%) of the 1044 without stent had GB nonvisualization (P < 0.0001). CONCLUSIONS In patients with stents, cholescintigraphy using morphine augmentation or 4-hour delayed imaging is futile to evaluate for AC because the frequency of GB nonvisualization is high and the specificity of GB visualization is low. It is unknown whether further delayed imaging at 24 hours would improve the study efficacy in this population.

Abstract
BACKGROUND AND AIM Tumor involvement to the orifice of cystic duct (OCD) is a risk factor for cholecystitis after self-expandable metallic stent (SEMS) placement, but its prevention is still difficult. We conducted this multicenter analysis to clarify a type of SEMS or a method to place SEMS which would decrease the incidence of cholecystitis after SEMS placement. METHODS The incidence of cholecystitis was studied in consecutive patients receiving SEMS for distal malignant biliary obstruction in five tertiary care centers. Multiple logistic regression analysis was performed to evaluate risk factors for cholecystitis. RESULTS A total of 376 patients who received SEMS placement for distal malignant biliary obstruction were analyzed. Tumor involvement to OCD was diagnosed in 25.3%. Overall incidence of cholecystitis was 6.9%. Cholecystitis was observed in 8.0% of 300 patients with covered SEMS, 16.8% of 95 patients with tumor involvement to OCD, 10.8% of 234 patients with SEMS of high axial force (AF), and 12.0% of 158 patients with SEMS length ≤ 60 mm. In the multivariate analysis, tumor involvement to OCD (odds ratio [OR] 5.40, P < 0.001), SEMSs with high AF (OR 5.33, P = 0.002), and SEMS length ≤ 60 mm (OR 3.19, P = 0.010) are risk factors. Among patients with tumor involvement to OCD, the incidence of cholecystitis in SEMS with high and low AF was 25.0% and 5.0%, respectively. CONCLUSION This study with an expanded cohort reconfirmed tumor involvement to OCD as a risk factor for cholecystitis after SEMS placement. SEMS with low AF might decrease cholecystitis.

Abstract
BACKGROUND/OBJECTIVES In endoscopic retrograde cholangiopancreatography, post-sphincterotomy bleeding (PSB) is a common complication of biliary sphincterotomy. Recently, the temporary placement of fully-covered metal stents (FCMS) into the biliary tree in order to achieve a tamponade effect has been described as an additional therapeutic option for PSB. The aim of this article is to review the literature on FCMS for hemostasis in PSB and update the treatment algorithm for this complication. METHODS A PubMed literature search was conducted using the search terms post-sphincterotomy, bleeding, and stent. 33 articles were reviewed, along with their references, and four were found to describe the use of FCMS for hemostasis in PSB. RESULTS A total of 21 patient cases were described in the four articles. All patients received FCMS for PSB hemostasis following the application and subsequent failure of traditional therapies (conventional pharmacologic injection, thermal or electrocoagulation, and mechanical therapy (balloon tamponade or endoclip)). Successful hemostasis was achieved in all patients through FCMS placement. No major complications were observed. CONCLUSION These 21 cases demonstrate that FCMS are a viable therapeutic option for PSB. It is reasonable to consider stent placement for patients in which traditional interventions fail in order to avoid the need for angiographic or surgical hemostasis.

Abstract
BACKGROUND Self-expandable metal stents (SEMSs) are used to relieve malignant biliary obstruction. OBJECTIVE To compare outcomes between covered self-expandable metal stents (CSEMSs) and uncovered self-expandable metal stents (USEMSs) in malignant biliary obstruction. DESIGN Retrospective cohort study. SETTING Tertiary cancer center. PATIENTS Patients with malignant biliary obstruction. INTERVENTIONS Placement of CSEMS or USEMS. MAIN OUTCOME MEASUREMENTS Time to recurrent biliary obstruction (TRO), overall survival (OS), and adverse events. RESULTS From January 2000 to June 2011, 749 patients received SEMSs: 171 CSEMSs and 578 USEMSs. At 1 year, there was no significant difference in the percentage of patients with recurrent obstruction (CSEMSs, 35% vs USEMSs, 38%) and survival (CSEMSs, 45% vs USEMSs, 49%). There was no significant difference in the median OS (CSEMSs, 10.4 months vs USEMSs, 11.8 months; P = .84) and the median TRO (CSEMSs, 15.4 months vs USEMSs, 26.3 months; P = .61). The adverse event rate was 27.5% for the CSEMS group and 27.7% for the USEMS group. Although tumor ingrowth with recurrent obstruction was more common in the USEMS group (76% vs 9%, P < .001), stent migration (36% vs 2%, P < .001) and acute pancreatitis (6% vs 1%, P < .001) were more common in the CSEMS group. LIMITATIONS Retrospective study. CONCLUSIONS There was no significant difference in the patency rate or overall survival between CSEMSs and USEMSs for malignant distal biliary strictures. The CSEMS group had a significantly higher rate of migration and pancreatitis than the USEMS group. No significant SEMS-related adverse events were observed in patients undergoing neoadjuvant chemoradiation or surgical resection.

Abstract
To evaluate clinical safety and efficacy of percutaneous transhepatic hybrid biliary prostheses for palliative treatment in patients with common bile duct obstruction caused by advanced malignancies. A total of 13 consecutive patients was treated with percutaneous transhepatic biliary endoprostheses concurrently using both plastic and metallic stents. Serum total bilirubin levels before and after stent placement were evaluated. The technical success rate, the period with no obstructive jaundice, patient survival and complications were also assessed. Median bilirubin levels decreased from 3.8 mg/dL before to 1.2 mg/dL after stent placement, and this difference was statistically significant. The median no-jaundice period after bile duct stent placement was 6.0 months (range: 2-11 months), and overall survival time was 7.0 months. Of the 13 patients, nine did not have recurrent jaundice by the time of death, whereas four (31%) had recurrent jaundice. A second intervention was performed in these four patients. A new plastic stent was placed and jaundice did not recur up to the time of death. No serious complications such as cholangitis, pancreatitis or bile duct perforation developed. Percutaneous transhepatic hybrid biliary endoprostheses using both plastic and metallic stents can be useful as non-invasive palliative treatment to relieve jaundice in patients with malignant obstructive jaundice.

Abstract
BACKGROUND Anastomotic biliary strictures (ABSs) are common after liver transplantation, especially with living donors. The strategy of balloon dilation and multiple plastic stents (MPSs) is effective in treating ABSs, but requires multiple ERCPs with the associated risks, cost, and patient burden. Covered self-expandable metal stents (SEMSs) have been increasingly used in this setting. However, it is not clear whether there are definite advantages of using SEMSs over MPSs. OBJECTIVE To compare the efficacy and safety of MPSs and SEMSs in ABS after orthotopic liver transplantation (OLT) and living donor liver transplantation (LDLT). DESIGN Systematic review by searching MEDLINE and EMBASE databases. PATIENTS OLT and LDLT patients. INTERVENTIONS MPSs versus SEMSs. MAIN OUTCOME MEASUREMENTS Stricture resolution and adverse event rates. RESULTS Eight studies (446 patients) using MPSs in OLT, 3 studies (120 patients) using MPSs in LDLT, and 10 studies (200 patients) using SEMSs fulfilled the inclusion and exclusion criteria. The stricture resolution rates were highest (94%-100%) when MPS duration was 12 months or longer. The stricture resolution rates with SEMSs in OLT patients were also high when stent duration was 3 months or longer (80%-95%) compared with a duration less than 3 months (53%-88%). Although the overall adverse event rates were low, the overall SEMS migration rate was significant at 16%. LIMITATIONS No randomized, controlled trials were identified; only small case series using either MPSs or SEMSs were included. CONCLUSIONS Although SEMSs appeared to be a promising option in the endoscopic management of ABSs after liver transplantation, current evidence does not suggest a clear advantage of SEMS use over MPSs for this indication.

Abstract
BACKGROUND Biliary partially covered self-expandable metal stents (PC-SEMS) offer prolonged relief of symptoms of biliary obstruction but may induce complications including pancreatitis, cholecystitis and migration. AIMS To assess efficacy and safety of the ComVi partially covered self-expandable metal stents as primary palliative treatment of distal malignant biliary obstruction. METHODS Seventy patients (mean age 69.2 years) with distal malignant biliary strictures were prospectively included and underwent endoscopic retrograde cholangio-pancreatography and partially covered self-expandable metal stents placement. Follow-up was done for 12 months. self-expandable metal stents patency, survival and complication-rate after partially covered self-expandable metal stents placement were evaluated. RESULTS Overall median survival time was 190 days (30-856). Forty-four patients (62.8%) died after median 175.5 days (30-614) without signs of stent dysfunction; 37 patients (52.8%) were alive after 6 months without signs of self-expandable metal stents occlusion. Survival rapidly dropped between 8 and 12 months after treatment. Survival was not influenced by sex (P = 0.1) or type of neoplasia (P = 0.178). Median survival was longer (254 days [44-836]) in patients who underwent chemotherapy (P < 0.0001). Partially covered self-expandable metal stents occlusion had 24 (35.7%) patients 154 days (35-485) after treatment. Median survival after re-treatment was 66 days (13-597). Cholecystitis occurred in one patient (1.7%). CONCLUSIONS The ComVi partially covered self-expandable metal stents is effective for palliation of biliary obstruction secondary to distal malignant biliary strictures. Self-expandable metal stents patency during follow-up is satisfactory without significant complications.

Abstract
Malignant biliary obstruction can arise from intrahepatic, extrahepatic, and hilar locations from either primary or metastatic disease. Biliary-enteric surgical bypass has been surpassed in the last 20 years by endoscopic balloon dilation and stenting. The goal of stenting for biliary decompression is to palliate obstructive symptoms; it has not been shown that survival is affected by stenting alone. Novel endoscopic therapies, including photodynamic therapy and radiofrequency ablation, have been evaluated and show promise. Both therapies seem to be safe and effective in the treatment of malignant bile duct strictures but are in need of prospective studies of longer duration.

Abstract
Biliary and pancreatic stents are used in a variety of benign and malignant conditions including strictures and leaks and in the prevention of post-ERCP pancreatitis.Both plastic and metal stents are safe, effective, and easy to use. SEMSs have traditionally been used for inoperable malignant disease. Covered SEMSs are now being evaluated for use in benign disease. Increasing the duration of patency of both plastic and metal stents remains an important area for future research.

Abstract
Endoscopic biliary stent placement is widely accepted as palliation for malignant biliary obstruction or as a treatment of benign biliary stricture. Although various biliary stent designs have become available since self-expandable metallic stents were introduced, no single ideal stent has been developed. An ideal stent should be patent until death, or surgery, in patients with resectable malignant biliary obstruction. Fewer complications, maneuverability, cost-effectiveness, and removability are also important factors. Alternatively, should we develop a novel method for biliary drainage other than biliary stenting via endoscopic retrograde cholangiopancreatography? This article reviews the current status of biliary stenting for malignant biliary obstructions.

Abstract
BACKGROUND Covered self-expandable metal stents (CSEMSs) were developed to prevent tumor ingrowth, but stent migration is one of the problems with CSEMSs. OBJECTIVE To evaluate a new, commercially available CSEMS with flared ends and low axial force compared with a commercially available CSEMS without the anti-migration system and high axial force. DESIGN Multicenter, prospective study with a historical cohort. SETTING Twenty Japanese referral centers. PATIENTS This study involved patients with unresectable distal malignant biliary obstruction. INTERVENTION Placement of a new, commercially available, partially covered SEMS. MAIN OUTCOME MEASUREMENTS Recurrent biliary obstruction rate, time to recurrent biliary obstruction, stent-related complications, survival. RESULTS Between April 2009 and March 2010, 141 patients underwent partially covered nitinol stent placement, and between May 2001 and January 2007, 138 patients underwent placement of partially covered stainless stents as a historical control. The silicone cover of the partially covered nitinol stents prevented tumor ingrowth. There were no significant differences in survival (229 vs 219 days; P = .250) or the rate of recurrent biliary obstruction (33% vs 38%; P = .385) between partially covered nitinol stents and partially covered stainless stents. Stent migration was less frequent (8% vs 17%; P = .019), and time to recurrent biliary obstruction was significantly longer (373 vs 285 days; P = .007) with partially covered nitinol stents. Stent removal was successful in 26 of 27 patients (96%). LIMITATIONS Nonrandomized, controlled trial. CONCLUSION Partially covered nitinol stents with an anti-migration system and less axial force demonstrated longer time to recurrent biliary obstruction with no tumor ingrowth and less stent migration.

Abstract
BACKGROUND Endoscopic biliary stenting is a well-established palliative treatment in patients with unresectable malignant biliary strictures. Obstruction of uncovered self-expanding metal stent (SEMS) due to tumor ingrowth is the most frequent complication. Partially covered SEMS might increase stent patency but could favor complications related to stent covering, such as pancreatitis, cholecystitis, and migration. The aim of this study was to evaluate the efficacy and safety of partially covered SEMS in patients with an unresectable malignant biliary stricture. METHODS Patients with malignant extrahepatic biliary obstruction treated endoscopically with partially covered SEMS were included in this multicenter, prospective, nonrandomized study. RESULTS One hundred ninety-nine patients were endoscopically treated with partially covered SEMS in 32 Spanish hospitals. Clinical success after deep cannulation was 96%. Early complications occurred in 4% (3 pancreatitis, 2 cholangitis, 1 hemorrhage, 1 perforation, and 1 cholecystitis). Late complications occurred in 19.5% (18 obstructions, 10 migrations, 6 cholangitis without obstruction, 3 acute cholecystitis, and 2 pancreatitis), with no tumor ingrowth in any case. Median stent patency was 138.9 ± 112.6 days. One-year actuarial probability of stent patency was 70% and that of nonmigration was 86%. Multivariate analysis showed adjuvant radio- or chemotherapy as the only independent predictive factor of stent patency and previous insertion of a biliary stent was the only predictive factor of migration. CONCLUSIONS The partially covered SEMS was easily inserted, had a high clinical success rate, and prevented tumor ingrowth. The incidence of possible complications related to stent coverage, namely, migration, pancreatitis, and cholecystitis, was lower than in previously published series.

Abstract
Pancreatic cancer is devastating due to its poor prognosis. Patients require a multidisciplinary approach to guide available options, mostly palliative because of advanced disease at presentation. Palliation including relief of biliary obstruction, gastric outlet obstruction, and cancer-related pain has become the focus in patients whose cancer is determined to be unresectable. Endoscopic stenting for biliary obstruction is an option for drainage to avoid the complications including jaundice, pruritus, infection, liver dysfunction and eventually failure. Enteral stents can relieve gastric obstruction and allow patients to resume oral intake. Pain is difficult to treat in cancer patients and endoscopic procedures such as pancreatic stenting and celiac plexus neurolysis can provide relief. The objective of endoscopic palliation is to primarily address symptoms as well improve quality of life.

Abstract
Malignant biliary obstruction results in jaundice, often with symptoms that decrease the quality of life. Biliary stent placement has largely supplanted surgical bypass for palliation of malignant biliary obstruction. Traditional rigid plastic stents are commonly used, inexpensive and easily removed, although with limited duration of stent patency. Self-expandable metal stents (SEMS) attain larger luminal diameters and provide longer patency than traditional rigid plastic stents in patients with distal bile duct obstruction. SEMS are composed of a variety of metals and can be uncoated, partially covered, or fully covered. Data do not support a prolongation of patency with covered SEMS for distal obstruction, although they have the potential for removability. The data to support SEMS for palliation of hilar biliary obstruction are not as convincing and reintervention for stent occlusion can be difficult. In this article, the design and performance of expandable metal stents for treatment of malignant biliary obstruction will be reviewed.

Radiotherapy and chemotherapy as therapeutic strategies in extrahepatic biliary duct carcinoma. Strahlenther Onkol 2010; 186:672-80.

Abstract
PURPOSE this report aims to provide an overview on radiotherapy and chemotherapy in extrahepatic biliary duct carcinoma (BDC). PATIENTS AND METHODS a PubMed research identified clinical trials in BDC through April 1, 2010 including randomised controlled trials, SEER analyses and retrospective trials. Additionally, publications on the technical progress of radiotherapy in or close to the liver were analysed. RESULTS most patients with cholangiocarcinoma present with unresectable disease (80-90%), and more than half of the resected patients relapse within 1 year. Adjuvant and palliative treatment options need to be chosen carefully since 50% of the patients are older than 70 years at diagnosis. Adjuvant radiotherapy or chemotherapy after complete resection (R0) has not convincingly shown a prolongation of survival but radiotherapy did after R1 resection. However, data suggest that liver transplantation could offer long-term survival in selected patients when combined with neoadjuvant chemoradiotherapy in patients with marginally resectable disease. For patients with unresectable biliary tract carcinoma (BTC), palliative stenting was previously the treatment of choice. But recent SEER analyses show that radiotherapy prolongs survival, relieves symptoms and contributes to biliary decompression and should be regarded as the new standard. Novel technical advances in radiotherapy may allow for dose-escalation and could significantly improve outcome for patients with cholangiocarcinoma. CONCLUSION both the literature and recent technical progress corroborate the role of radiotherapy in BDC offering chances for novel clinical trials. Progress is less pronounced in chemotherapy.

Abstract
BACKGROUND Covered biliary metal stents have been developed to prevent tumor ingrowth. Previous comparative studies are limited and often include few patients. OBJECTIVE To compare differences in stent patency, patient survival, and complication rates between covered and uncovered nitinol stents in patients with malignant biliary obstruction. DESIGN Randomized, multicenter trial conducted between January 2006 and October 2008. SETTING Ten sites serving a total catchment area of approximately 2.8 million inhabitants. PATIENTS A total of 400 patients with unresectable distal malignant biliary obstruction. INTERVENTIONS ERCP with insertion of covered or uncovered metal stent. Follow-up conducted monthly for symptoms indicating stent obstruction. MAIN OUTCOME MEASUREMENTS Time to stent failure, survival time, and complication rate. RESULTS The patient survival times were 116 days (interquartile range 242 days) and 174 days (interquartile range 284 days) in the covered and uncovered stent groups, respectively (P = .320). The first quartile stent patency time was 154 days in the covered stent group and 199 days in the uncovered stent group (P = .326). There was no difference in the incidence of pancreatitis or cholecystitis between the 2 groups. Stent migration occurred in 6 patients (3%) in the covered group and in no patients in the uncovered group (P = .030). LIMITATIONS Randomization was not blinded. CONCLUSIONS There were no significant differences in stent patency time, patient survival time, or complication rates between covered and uncovered nitinol metal stents in the palliative treatment of malignant distal biliary obstruction. However, covered stents migrated significantly more often compared with uncovered stents, and tumor ingrowth was more frequent in uncovered stents.

Abstract
BACKGROUND The most common complication of uncovered biliary self-expandable metal stents (SEMSs) is tumor ingrowth. The addition of an impenetrable covering may prolong stent patency. OBJECTIVE To compare stent patency between uncovered and partially covered SEMSs in malignant biliary obstruction. DESIGN Multicenter randomized trial. SETTING Four teaching hospitals. PATIENTS Adults with inoperable distal malignant biliary obstruction. INTERVENTIONS Uncovered or partially covered SEMS insertion. MAIN OUTCOME MEASURES Time to recurrent biliary obstruction, patient survival, serious adverse events, and mechanism of recurrent biliary obstruction. RESULTS From October 2002 to May 2008, 129 patients were randomized. Recurrent biliary obstruction was observed in 11 of 61 uncovered SEMSs (18%) and 20 of 68 partially covered SEMSs (29%). The median times to recurrent biliary obstruction were 711 days and 357 days for the uncovered and partially covered SEMS groups, respectively (P = .530). Median patient survival was 239 days for the uncovered SEMS and 227 days for the partially covered SEMS groups (P = .997). Serious adverse events occurred in 27 (44%) and 42 (62%) patients in the uncovered and partially covered SEMS groups, respectively (P = .046). None of the uncovered and 8 (12%) of the partially covered SEMSs migrated (P = .0061). LIMITATIONS Intended sample size was not reached. Allocation to treatment groups was unequal. CONCLUSIONS There was no significant difference in time to recurrent biliary obstruction or patient survival between the partially covered and uncovered SEMS groups. Partially covered SEMSs were associated with more serious adverse events, particularly migration.

Abstract
We herein report two patients with unresectable malignant biliary stricture who underwent stenting with a newly developed fully-covered metal stent. In the first case of lower-middle bile duct cancer, a stent was placed through the stenosis. In the second case of middle bile duct stricture due to lymph node metastases from gallbladder cancer, a stent was placed in the bile duct across the stenosis. No procedure-related complications were observed. Unevenness of the outer surface and a low shortening ratio are expected to lessen the occurrence of complications characteristic of covered metal stents such as stent migration and bile duct kinking.

Abstract
BACKGROUND There are conflicting data on the risk of post-ERCP pancreatitis (PEP) related to self-expandable metallic stents (SEMSs). OBJECTIVE To compare rates of PEP in patients who undergo biliary drainage with SEMSs or polyethylene stents (PSs). DESIGN Retrospective, cohort study. SETTING Tertiary-care medical center. PATIENTS This study involved patients undergoing ERCP for malignant biliary obstruction between January 2005 and October 2008. INTERVENTION First-time placement of a SEMS or PS for biliary decompression. MAIN OUTCOME MEASUREMENTS Early post-ERCP complications, particularly PEP. RESULTS We identified 544 eligible patients, 248 SEMSs (102 covered), and 296 PSs. The etiology of malignant biliary obstruction was similar between groups, with 55% from pancreatic cancer. The frequency of PEP was significantly higher in the SEMS group (7.3%) versus the PS group (1.3%) (OR 5.7 [95% CI, 1.9-17.1]). On univariate analysis, patient age of <40 years, a history of PEP, and at least 1 pancreatic duct injection were also significant predictors of PEP, whereas female sex and having pancreatic cancer were not. When significant variables were added to a multiple-predictor regression model, the odds of PEP from SEMS placement increased to 6.8 (95% CI, 2.2, 21.4). However, the frequency of PEP was similar between covered (6.9%) and uncovered (7.5%) SEMSs (OR 0.9 [CI, 0.3-2.4]). Purported SEMS-specific risk factors, including the use of cSEMSs, overlapping SEMSs, or having a biliary sphincterotomy were not found to be significant contributors to the higher risk. LIMITATIONS Retrospective design. CONCLUSION After we controlled for confounding variables, the frequency of PEP was significantly higher with placement of a SEMS compared with a PS. Rates of PEP were comparable with use of covered and uncovered SEMSs.

Abstract
PURPOSE Covered self-expanding metal stents (CSEMS) have been used for palliation of malignant distal biliary strictures. Occlusion of the cystic duct by CSEMS may be complicated by cholecystitis. This potentially could be prevented by placement of a transpapillary gallbladder stent (GBS). PATIENTS AND METHODS Between 11/2006 and 10/2007, a total of 73 patients (50 male) aged 65 +/- 14 years underwent CSEMS placement for palliation of malignant obstructive jaundice. In cases where CSEMS placement caused occlusion of the cystic duct, a 7 French transpapillary pigtail gallbladder stent (GBS) was inserted to prevent cholecystitis. RESULTS Of the 73 patients, 18 had a prior cholecystectomy; 34 had the CSEMS placed below the cystic duct insertion. In 19 out of the 21 patients who had a CSEMS covering the cystic duct ostium, GBS placement was attempted, which was successful in 11 individuals (58%). An attempt to access the gallbladder was complicated by wire perforation of the cystic duct in three patients; one patient requiring emergent cholecystostomy tube placement. None of the patients who underwent successful GBS placement developed cholecystitis. One GBS dislodged and was repositioned. Cholecystitis occurred in two (20%) of the ten patients without transpapillary gallbladder decompression who had a CSEMS covering the cystic duct. CONCLUSIONS The ideal placement of a CSEMS is below the cystic duct insertion. Should the cystic duct ostium be occluded, placement of a GBS should be considered to minimize the risk of cholecystitis.

Abstract
Cholangiocarcinomas (CCAs) are rare malignancies that arise from the biliary epithelium. Intrahepatic CCAs usually present as mass lesions that are asymptomatic or cause nonspecific systemic symptoms such as fatigue, fever, and weight loss. Hilar and extrahepatic tumors most commonly present with jaundice, though cholangitis also can be seen. Tumor markers such as carbohydrate antigen 19-9 and carcinoembryonic antigen have been used to diagnose CCA, but these are nonspecific and may be elevated in infection, inflammation, or any obstruction. Endoscopic retrograde cholangiopancreatography (ERCP) has been used for the diagnosis and management of CCA for many years. This article summarizes the data regarding the application of ERCP in the diagnosis and management of CCA.

Abstract
INTRODUCTION Controversy exists over the preferred technique of preoperative biliary drainage (PBD) in patients with hilar cholangiocarcinoma (HCCA) requiring major liver resection. The current study compared outcomes of endoscopic biliary drainage (EBD) and percutaneous transhepatic biliary drainage (PTBD) in patients with resectable HCCA. METHODS One hundred fifteen consecutive patients were explored for HCCA between 2001 and July 2008 and assigned by initial PBD procedure to either EBD or PTBD. RESULTS Of these patients, 101 (88%) underwent PBD; 90 patients underwent EBD as primary procedure, and 11 PTBD. The technical success rate of initial drainage was 81% in the EBD versus 100% in the PTBD group (P = 0.20). Stent dislocation was similar in the EBD and PTBD groups (23% vs. 20%, P = 0.70). Infectious complications were significantly more common in the endoscopic group (48% vs. 9%, P < 0.05). Patients in the EBD group underwent more drainage procedures (2.8 vs. 1.4, P < 0.01) and had a significantly longer drainage period until laparotomy (mean 15 weeks vs. 11 weeks in the PTBD group; P < 0.05). In 30 patients, EBD was converted to PTBD due to failure of the endoscopic approach. CONCLUSIONS Preoperative percutaneous drainage could outperform endoscopic stent placement in patients with resectable HCCA, showing fewer infectious complications, using less procedures.

Abstract
BACKGROUND Covered self-expandable metallic stents (SEMSs) are designed to prevent tumor ingrowth and can be removed if necessary. Only limited comparative data are available on the performance of covered SEMSs after primary placement versus reintervention. OBJECTIVE To assess the effectiveness and safety of covered SEMS placement either as primary treatment or reintervention in patients requiring palliation of malignant biliary obstruction. DESIGN Retrospective clinical cohort study. SETTING Tertiary referral center. PATIENTS This study involved 104 patients with unresectable malignant biliary strictures. INTERVENTION Covered biliary SEMS placement. MAIN OUTCOME MEASUREMENTS Stent patency, technical success, and patient survival. RESULTS Covered SEMSs were placed as primary treatment in 48 patients (46%), and reintervention was performed in 56 patients (54%). At 3, 6, and 12 months thereafter, the Kaplan-Meier estimated fractions of all patients with patent stents were 94%, 84%, and 58%, respectively. Covered SEMSs remained patent until the patient's death in 75 of 89 nonsurvivors (84%). Although patency rates 3, 6, and 12 months after primary placement (100%, 93%, and 82%, respectively) were higher than those after reintervention (90%, 78%, and 48%, respectively), the differences were not statistically significant (P = .057). Overall, the most frequent adverse events were cholangitis (7%) and stent migration (4%). LIMITATIONS The distribution of stricture locations differed among the groups, and survival data suggested the presence of more extensive disease in the primary treatment group at baseline. CONCLUSION The clinical utility and safety of primary covered SEMS placement were confirmed. This study provides the most extensive evidence to date that reintervention with a covered SEMS can provide a useful palliative option.

Abstract
Several advances in diagnosis, treatment and palliation of cholangiocarcinoma (CC) have occurred in the last decades. A multidisciplinary approach to this disease is therefore recommended. CC is a relatively rare tumor and the main risk factors are: chronic inflammation, genetic predisposition and congenital abnormalities of the biliary tree. While the incidence of intra-hepatic CC is increasing, the incidence of extra-hepatic CC is trending down. The only curative treatment for CC is surgical resection with negative margins. Liver transplantation has been proposed only for selected patients with hilar CC that cannot be resected who have no metastatic disease after a period of neoadjuvant chemo-radiation therapy. Magnetic resonance imaging/magnetic resonance cholangiopancreatography, positron emission tomography scan, endoscopic ultrasound and computed tomography scans are the most frequently used modalities for diagnosis and tumor staging. Adjuvant therapy, palliative chemotherapy and radiotherapy have been relatively ineffective for inoperable CC. For most of these patients biliary stenting provides effective palliation. Photodynamic therapy is an emerging palliative treatment that seems to provide pain relief, improve biliary patency and increase survival. The clinical utility of other emerging therapies such as transarterial chemoembolization, hepatic arterial chemoinfusion and high intensity intraductal ultrasound needs further study.

Abstract
BACKGROUND The Wallstent has remained the industry standard for biliary self-expanding metal stents (SEMSs). Recently, stents of differing designs, compositions, and diameters have been developed. OBJECTIVE To compare the new nitinol 6-mm and 10-mm Zilver stents with the 10-mm stainless steel Wallstent and determine the mechanism of obstruction. DESIGN Randomized, prospective, controlled study. SETTING Nine centers experienced in SEMS placement during ERCP. PATIENTS A total of 241 patients presenting between September 2003 and December 2005 with unresectable malignant biliary strictures at least 2 cm distal to the bifurcation. MAIN OUTCOME MEASUREMENT Stent occlusions requiring reintervention and death. RESULTS At interim analysis, a significant increase in occlusions was noted in the 6-mm Zilver group at the P = .04 level, resulting in arm closure but continued follow-up. Final study arms were 64, 88, and 89 patients receiving a 6-mm Zilver, 10-mm Zilver, and 10-mm Wallstent, respectively. Stent occlusions occurred in 25 (39.1%) of the patients in the 6-mm Zilver arm, 21 (23.9%) of the patients in the 10-mm Zilver arm, and 19 (21.4%) of the patients in the 10-mm Wallstent arm (P = .02). The mean number of days of stent patency were 142.9, 185.8, and 186.7, respectively (P = .057). No differences were noted in secondary endpoints, and the study was ended at the 95% censored study endpoints. Biopsy specimens of ingrowth occlusive tissue revealed that 56% were caused by benign epithelial hyperplasia. CONCLUSIONS SEMS occlusions were much more frequent with a 6-mm diameter SEMS and equivalent in the two 10-mm arms despite major differences in stent design, material, and expansion, suggesting that diameter is the critical feature. Malignant tumor ingrowth produced only a minority of the documented occlusions.

Abstract
One of the problems affecting metallic biliary stents is the difficulty of removing them, especially after a period of months or if they have migrated. Several approaches have been used to remove both covered and uncovered stents, although with different degrees of effectiveness. We report two new approaches to removing partially covered stents that migrated proximally and that impacted in the papillary area and distal common bile duct. One stent was removed by papillectomy and the other by using duodenoscopy-guided controlled radial expansion balloon dilation. In both cases, the stents were removed without severe complications for the patient, leaving a good caliber in the stenosis.
