Clin J Gastroenterol 2024; 17:352-355. [PMID: 38363445 DOI: 10.1007/s12328-024-01920-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Accepted: 01/03/2024] [Indexed: 02/17/2024]
Abstract
Hepatic artery pseudoaneurysms have been reported to occur in approximately 1% of cases after metal stenting for malignant biliary obstruction. In contrast, only a few cases have been reported as complications after plastic stenting for benign biliary disease. We report a 61-year-old man with cholangitis who presented with a rare complication of hemobilia after implantation of 7 Fr double pigtail plastic biliary stents. No bleeding was observed approximately one month after biliary stent tube removal. Contrast-enhanced CT scan revealed a circularly enhanced lesion (5 mm in diameter) in the arterial phase at the tip of the previously inserted plastic bile duct stent. Color Doppler ultrasonography enhanced the lesion and detected arterial blood flow inside. He was diagnosed with a hepatic artery pseudoaneurysm. However, he had no risk factors such as prolonged catheterization, severe cholangitis, liver abscess, or long-term steroid use. Superselective transarterial embolization using two metal microcoils was successfully completed without damage to the surrounding liver parenchyma. If hemobilia is suspected after insertion of a plastic bile duct stent, immediate monitoring using contrast-enhanced computed tomography or Doppler ultrasonography is recommended.

J Clin Med 2023; 12:3786. [PMID: 37297981 PMCID: PMC10253433 DOI: 10.3390/jcm12113786] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 05/18/2023] [Accepted: 05/28/2023] [Indexed: 06/12/2023] Open
Abstract
PURPOSES The management of patients with iatrogenic bile duct injuries (IBDI) is a challenging field, often with dismal medico legal projections. Attempts to classify IBDI have been made repeatedly and the final results were either analytical and extensive but not useful in everyday clinical practice systems, or simple and user friendly but with limited clinical correspondence approaches. The purpose of the present review is to propose a novel, clinical classification system of IBDI by reviewing the relevant literature. METHODS A systematic literature review was conducted by performing bibliographic searches in the available electronic databases, including PubMed, Scopus, and the Cochrane Library. RESULTS Based on the literature results, we propose a five (5) stage (A, B, C, D and E) classification system for IBDI (BILE Classification). Each stage is correlated with the recommended and most appropriate treatment. Although the proposed classification scheme is clinically oriented, the anatomical correspondence of each IBDI stage has been incorporated as well, using the Strasberg classification. CONCLUSIONS BILE classification represents a novel, simple, and dynamic in nature classification system of IBDI. The proposed classification focuses on the clinical consequences of IBDI and provides an action map that can appropriately guide the treatment plan.

Real-life patency of plastic biliary stents in the pandemic era: is stent removal after 6 months safe and effective? Scand J Gastroenterol 2023:1-7.

Abstract
BACKGROUND The SARS-CoV-2 pandemic conditioned the optimal timing of some endoscopic procedures. ESGE guidelines recommend replacement or removal of the plastic biliary stents within 3-6 months to reduce the risk of complications. Our aim was to analyse the outcomes of patients who had delayed plastic biliary stent removal following endoscopic retrograde cholangiopancreatography (ERCP) in the pandemic era. METHODS Retrospective study including consecutive ERCPs with plastic biliary stent placement between January 2019 and December 2021. Delayed removal was defined as presence of biliary stent >6 months after ERCP. The evaluated outcomes were stent migration, stent dysfunction, obstructive jaundice, cholangitis, acute pancreatitis, hospitalization, and biliary pathology-related mortality. RESULTS One-hundred and twenty ERCPs were included, 56.7% male patients, with a mean age of 69.4 ± 15.7 years. Indications for plastic biliary stent insertion were choledocholithiasis (72.5%), benign biliary stricture (20.0%), and post-cholecystectomy fistula (7.5%). Delayed stent removal occurred in 32.5% of the cases. The median time to stent removal was 3.5 ± 1.3 months for early removal and 8.6 ± 3.1 months for delayed removal. Patients who had delayed stent removal did not have a significantly higher frequency of stent migration (20.5 vs 11.1%, p = 0.17), stent dysfunction (17.9 vs 13.6%, p = 0.53), hospitalization (17.9 vs 14.8%, p = 0.66), obstructive jaundice (2.6 vs 0.0%, p = 0.33), cholangitis (10.3 vs 13.6%, p = 0.77), acute pancreatitis (0.0 vs 1.2%, p = 1.0), or biliary pathology-related mortality (2.6 vs 1.2%, p = 0.55). CONCLUSIONS Delayed plastic biliary stent removal does not seem to have a negative impact on patients' outcomes. In the current pandemic situation, while scheduled endoscopic procedures may have to be postponed, elective removal of plastic biliary stents can be safely deferred.

Abstract
Bile duct injury (BDI) is a dangerous complication of cholecystectomy, with significant postoperative sequelae for the patient in terms of morbidity, mortality, and long-term quality of life. BDIs have an estimated incidence of 0.4-1.5%, but considering the number of cholecystectomies performed worldwide, mostly by laparoscopy, surgeons must be prepared to manage this surgical challenge. Most BDIs are recognized either during the procedure or in the immediate postoperative period. However, some BDIs may be discovered later during the postoperative period, and this may translate to delayed or inappropriate treatments. Providing a specific diagnosis and a precise description of the BDI will expedite the decision-making process and increase the chance of treatment success. Subsequently, the choice and timing of the appropriate reconstructive strategy have a critical role in long-term prognosis. Currently, a wide spectrum of multidisciplinary interventions with different degrees of invasiveness is indicated for BDI management. These World Society of Emergency Surgery (WSES) guidelines have been produced following an exhaustive review of the current literature and an international expert panel discussion with the aim of providing evidence-based recommendations to facilitate and standardize the detection and management of BDIs during cholecystectomy. In particular, the 2020 WSES guidelines cover the following key aspects: (1) strategies to minimize the risk of BDI during cholecystectomy; (2) BDI rates in general surgery units and review of surgical practice; (3) how to classify, stage, and report BDI once detected; (4) how to manage an intraoperatively detected BDI; (5) indications for antibiotic treatment; (6) indications for clinical, biochemical, and imaging investigations for suspected BDI; and (7) how to manage a postoperatively detected BDI.

Abstract
BACKGROUND A reliable large animal model of benign biliary stricture (BBS) is essential to study endoscopic management of BBS. The aim of this study was to establish a swine BBS model of endobiliary electrothermal injury with a diathermic sheath and screen out the optimal energy dose. MATERIALS AND METHODS Twelve swine were equally randomized into a low (20 W), a medium (30 W), and a high (40 W)-dose group. Endobiliary electrothermal injury was applied to the common bile duct using a diathermic sheath at different energy doses for 20 seconds via endoscopic retrograde cholangiopancreatography. Cholangiographic findings and liver function were evaluated weekly after thermal injury. Two animals from each group were sacrificed at 2 weeks and the other 2 sacrificed 4 weeks after thermal injury for histopathologic evaluation. RESULTS BBS was established successfully in 10 of the 12 animals. Two of the 4 animals in low-dose group did not produce biliary stricture at 4 weeks; in medium-dose group, BBS was induced in both animals at 2 weeks without causing severe complications; and in high-dose group, BBS was produced in 4 animals at 2 weeks, causing perforation and abdominal abscess formation in 1 animal. CONCLUSIONS A safe and reproducible swine model of BBS could be established successfully by applying endobiliary electrothermal injury with a diathermic sheath at 30 W for 20 seconds.

Abstract
Prolonged indwelling of endoscopically placed biliary plastic stents may lead to complications. We conducted a retrospective analysis of patients who underwent endoscopic retrograde cholangio-pancreaticography (ERCP) at our centre in 2017 and were noted to have retained biliary plastic stents ( > 3 months after an index ERCP). A total of 127 patients had previously placed biliary plastic stents, out of which 45 (35.4%) were retained. The median age of the latter was 52 years (range = 22-79 years) with 27 (60%) patients being men. The median duration of the retained stents was 144 days (range = 94-3292 days). The majority of the patients were asymptomatic. However, 9 (20%) patients had cholangitis, 2 (4.4%) had choledocholithiasis, 2 (4.4%) had cholangitic abscess and 1 (2.2%) developed septicaemia. Fortunately, all these complications could be managed medically and endoscopically. Retention of biliary plastic stents is a problem often overlooked and underestimated in clinical practice. Various measures need to be instituted to create awareness of this entity to prevent undesirable outcomes.

Biocompatible Polymer Materials with Antimicrobial Properties for Preparation of Stents. NANOMATERIALS 2019; 9:nano9111548.

Abstract
Biodegradable polymers are promising materials for use in medical applications such as stents. Their properties are comparable to commercially available resistant metal and polymeric stents, which have several major problems, such as stent migration and stent clogging due to microbial biofilm. Consequently, conventional stents have to be removed operatively from the patient's body, which presents a number of complications and can also endanger the patient's life. Biodegradable stents disintegrate into basic substances that decompose in the human body, and no surgery is required. This review focuses on the specific use of stents in the human body, the problems of microbial biofilm, and possibilities of preventing microbial growth by modifying polymers with antimicrobial agents.

Abstract
With an increasing number of hospital admissions, an average of 16-to 20 days in hospital per year, 34% of patients constantly taking pain medication, 57% in need of enzyme supplementation, and 29% with diabetes mellitus, chronic pancreatitis is a debilitating disease of high socio-economic relevance. In total, 33% of all patients suffering from chronic pancreatitis can no longer practice their original profession. The number of unemployed chronic pancreatitis patients due to prolonged stays in hospital or continued alcohol abuse is known to be as high as 40%. Continued alcohol abuse with a hazard ratio (HR) of 1.6, smoking with a HR of 1.4, and the presence of liver cirrhosis with a HR of 2.5 negatively affects the prognosis of chronic pancreatitis. In a patient cohort burdened with high co-morbidity, endoscopic therapy can provide short-term relief of symptoms. Endotherapy is the first line of management in chronic pancreatitis with symptomatic pancreatobiliary ductal obstruction. Further studies are required in certain key areas such as the use of fully covered self-expanding metallic stents for pancreatic ductal and biliary strictures. Long-term success rates can mainly be achieved by surgical procedures, which can be performed with acceptable morbidity in pancreatic centers. The current review focuses on the advantages and disadvantages of endoscopic and surgical treatment of chronic pancreatitis.

Abstract
BACKGROUND AND AIMS Self-expanding biodegradable biliary stents (BDBSs) have recently become available for use in endoscopic retrograde cholangiography (ERC). The aim was to evaluate the effectiveness and safety of novel BDBSs in iatrogenic cystic duct leaks and benign biliary strictures (BBSs). METHODS Patients providing informed consent were recruited for the prospective study. Braided self-expanding poly-dioxanone BDBSs were inserted using ERC during from 2014 to 2016. Repeated liver function tests and magnetic resonance imaging were performed during follow-up. The main outcomes were treatment success and adverse events. RESULTS Thirteen patients, 5 women, median age 67 years (range, 43-79) underwent BDBS insertion for iatrogenic cystic duct leak (n = 7) or BBS (n = 6). Stent insertion using ERC was successful in all cases. All bile leaks were treated uneventfully with BDBSs. In BBSs, the clinical success rate of BDBS therapy was 83% in a median of 21 months of follow-up (range, 14-25). Early ERC-related adverse events included 1 cholangitis (8%) and 1 pancreatitis (8%), both in the stricture group. During the first 90 days, 23% of patients were readmitted for mild cholangitis. CONCLUSIONS The short- and long-term safety of endoscopically inserted poly-dioxanone BDBSs was satisfactory. The management of cystic duct leaks and benign distal common bile duct strictures was highly successful. Episodes of mild cholangitis during stent indwelling seemed to be typical of BDBSs. The advantage of BDBSs is the avoidance of repeated endoscopy for stent removal. (Clinical trial registration number: NCT02353286.).

Liver transplant-related anastomotic biliary strictures: a novel, rapid, safe, radiation-sparing, and cost-effective management approach. Gastrointest Endosc 2018; 87:501-508.

Abstract
BACKGROUND AND AIMS Biliary strictures after orthotopic liver transplantation (OLT) are typically managed by sequential ERCP procedures, with incremental dilation of the stricture and stent exchange (IDSE) and placement of new stents. This approach resolves >80% of strictures after 12 months but requires costly, lengthy ERCPs with significant patient radiation exposure. Increasing awareness of the harmful effects of radiation, escalating healthcare costs, and decreasing reimbursement for procedures mandate maximal efficiency in performing ERCP. We compared the traditional IDSE protocol with a sequential stent addition (SSA) protocol, in which additional stents are placed across the stricture during sequential ERCPs, without stent removal/exchange or stricture dilation. METHODS Patients undergoing ERCP for OLT-related anastomotic strictures from 2010 to 2016 were identified from a prospectively maintained endoscopy database. Procedure duration, fluoroscopy time, stricture resolution rates, adverse events, materials fees, and facility fees were analyzed for IDSE and SSA procedures. RESULTS Seventy-seven patients underwent 277 IDSE and 132 SSA procedures. Mean fluoroscopy time was 64.5% shorter (P < .0001) and mean procedure duration 41.5% lower (P < .0001) with SSA compared with IDSE. SSA procedures required fewer accessory devices, resulting in significantly lower material (63.8%, P < .0001) and facility costs (42.8%, P < .0001) compared with IDSE. Stricture resolution was >95%, and low adverse event rates did not significantly differ. CONCLUSIONS SSA results in shorter, cost-effective procedures requiring fewer accessory devices and exposing patients to less radiation. Stricture resolution rates are equivalent to IDSE, and adverse events do not differ significantly, even in this immunocompromised population.

Abstract
OBJECTIVE Plastic biliary stents are commonly placed during endoscopic retrograde cholangiopancreatography (ERCP) and should be removed or replaced within 3 months to reduce the risk of stent obstruction. The aim of the study was to identify predictors and outcomes of patients who had delayed plastic biliary stent removal following ERCP. MATERIALS AND METHODS Consecutive patients who received ERCP with plastic biliary stent placement at Loma Linda University Medical Center (10/2004-6/2013) were identified. Delayed removal was defined as presence of stent >3 months after index ERCP. Multivariable regression analysis to identify baseline characteristics associated with delayed removal was performed. Clinical outcomes of stent obstruction (e.g., cholangitis, hospitalization, intensive care) were also collected for those with delayed removal. RESULTS Among 374 patients undergoing ERCP with plastic biliary stent, 71 (19%) had delayed stent removal. Patients who had anesthesia assistance (AOR = 3.8, 95%CI 1.2-11.4), non-English primary language (AOR = 3.0, 95%CI 1.5-6.2), and outpatient ERCP (AOR = 2.0, 95%CI 1.1-3.4) had increased while choledocholithiasis (AOR = 0.5, 95%CI 0.3-0.99) had lower odds of delayed stent removal. Among those with delayed removal, 13 (18%) were hospitalized for stent obstruction (5 (7%) had cholangitis, 8 (11%) were hospitalized for more than a week, and 3 (4%) required intensive care). CONCLUSIONS Almost one-fifth of patients who underwent ERCP with plastic biliary stent placement had delayed removal with nearly one-fifth of these patients requiring hospitalization for stent obstruction. Targeting patients at risk by improving communication and ease of scheduling an ERCP may reduce preventable adverse events associated with delayed biliary stent removal.

Abstract
BACKGROUND Endotherapy with plastic stent (PS) placement is the main modality for treating benign biliary strictures (BBSs). Fully covered self-expandable metal stents (FCSEMSs) are being increasingly used for BBS management, with high stricture resolution. However, traditional metal tents are associated with high migration, causing treatment failure. METHODS We investigated the efficacy and safety of a new FCSEMS for postsurgical BBS treatment and compared these parameters between the FCSEMS and PS treatment through retrospective analysis. The primary outcome measurements included stricture resolution, stricture recurrence, and complications. RESULTS In total, 69 patients were included, of whom 32 underwent FCSEMS treatment and 37 underwent PS treatment. The technical success rate and the number of endoscopic retrograde cholangiopancreatography procedures were similar between the groups. The median stenting duration was 5.2 months (range 1.5-15.3) in the FCSEMS group and 10.7 months (range 2.5-22.6) in the PS group (P < 0.01). The stents removal rate was 96.9% in the FCSEMS group and 94.6% in the PS group. The stricture resolution rate based on intention-to-treat analysis was 83.8% in the PS group and 84.4% (27/32) in the FCSEMS group (P = 0.947), whereas the rates from per-protocol analysis were 88.6% (31/35) and 87.1% (27/31), respectively (P = 0.574). Early and late complications were similar between the groups. The median follow-up time was 43 months (range 13-71). The stricture recurrence rate was 11.1% (3/27) in the FCSEMS group and 16.1% (5/31) in the PS group (P = 0.435). CONCLUSIONS The new FCSEMS and the PS approach showed similar efficacy and safety in postsurgical BBS treatment. However, the FCSEMS required fewer procedural steps and shorter stenting time, making it an effective alternative modality.

Abstract
The first clinical experience of endoscopically inserted polydioxanone biodegradable biliary stents (BDBS) in the treatment of benign biliary strictures is reported. Two patients with a benign common bile duct stricture were endoscopically treated with 8-mm-bore BDBS during endoscopic retrograde cholangiography. Both BDBS insertions were technically successful and without adverse events. At 6 months, the stricture resolution was excellent and BDBS degradation was predicted in repeated magnetic resonance imaging. The first experience with endoscopic BDBS seems promising in the treatment of benign biliary strictures. During 6 months of follow up, BDBS seemed sufficient for remodeling and resolution of strictures. Further studies are needed to confirm the effectiveness of biodegradable biliary stents in endoscopic management of benign biliary strictures.

Abstract
Stricture formation occurs in up to 40% of patients with inflammatory bowel disease (IBD). Patients are often symptomatic, resulting in significant morbidity, hospitalizations, and loss of productivity. Strictures can be managed endoscopically in addition to traditional surgical management (sphincteroplasty or resection of the affected bowel segments). About 3% to 5% patients with IBD develop primary sclerosing cholangitis (PSC), which results in stricture formation in the biliary tree, managed for the most part by endoscopic therapies. In this article, we discuss endoscopic management of strictures both in the alimentary tract and biliary tree in patients with IBD and/or PSC.

Abstract
BACKGROUND Benign biliary strictures (BBS) are primarily treated endoscopically with covered self-expandable metal stents (CSEMS). Biodegradable biliary stents (BDBS) may be the future of endoscopic therapy of BBS. The aim was to assess the expression of proteins related to tissue healing in BBS compared with the intact bile duct (BD), and to study the protein expression after therapy with CSEMS or BDBS. METHODS Pigs with ischemic BBS were endoscopically treated either with BDBS or CSEMS. Samples were harvested from pigs with intact BD (n = 5), untreated BBS (n = 5), and after six months of therapy with BDBS (n = 4) or CSEMS (n = 5) with subsequent histologic analysis. Two-dimensional electrophoresis with protein identification was performed to evaluate protein expression patterns. RESULTS In BBS, the expression of galectin-2 and annexin-A4 decreased, compared to intact BD. Treatment with biodegradable stents normalized galectin-2 level; with CSEMS therapy it remained low. Transgelin expression of intact BD and BBS remained low after BDBS treatment but increased after CSEMS therapy. Histologic analysis did not show unwanted foreign body reaction or hyperplasia in the BD in either group. CONCLUSIONS The expression of proteins related to tissue healing in BBS is different after treatment with biodegradable stents and CSEMS. Treatment with biodegradable stents may bring protein expression towards what is seen in intact BD. BDBS seem to have a good biocompatibility.

Abstract
Objective Plastic biliary stents used to relieve obstructive jaundice are frequently blocked by sediment, resulting in loss of drainage. We prepared stents coated with silver nanoparticles (AgNPs) and compared their ability to resist sedimentation with Teflon stents in a beagle model of obstructive jaundice. Methods AgNP-coated Teflon biliary stents were prepared by chemical oxidation–reduction and evaluated in an obstructive jaundice model that was produced by ligation of common bile duct (CBD); animals were randomized to two equal groups for placement of AgNP-coated or Teflon control stents. Liver function and inflammatory index were found to be similar in the two groups, and the obstruction was relieved. Stents were removed 21 days after insertion and observed by scanning and transmission electron microscopy. The AgNP coating was analyzed by energy dispersive X-ray analysis (EDXA), and the composition of sediment was assayed by Fourier-transform infrared (FTIR) spectroscopy. Results Electron microscopy revealed a black, closely adherent AgNP stent coating, with thicknesses of 1.5–6 µm. Sediment thickness and density were greater on Teflon than on AgNP-coated stents. EDXA confirmed the stability and integrity of the AgNP coating before and after in vivo animal experimentation. FTIR spectroscopy identified stent sediment components including bilirubin, cholesterol, bile acid, protein, calcium, and other substances. Conclusion AgNP-coated biliary stents resisted sediment accumulation in this canine model of obstructive jaundice caused by ligation of the CBD.

Abstract
Benign biliary strictures comprise a heterogeneous group of diseases. The most common strictures amenable to endoscopic treatment are post-cholecystectomy, post-liver transplantation, related to primary sclerosing cholangitis and to chronic pancreatitis. Endoscopic treatment of benign biliary strictures is widely used as first line therapy, since it is effective, safe, noninvasive and repeatable. Endoscopic techniques currently used are dilation, multiple plastic stents insertion and fully covered self-expandable metal stents. The main indication for dilation alone is primary sclerosing cholangitis related strictures. In the vast majority of the remaining cases, temporary placement of multiple plastic stents with/without dilation is considered the treatment of choice. Although this approach is effective, it requires multiple endoscopic sessions due to the short duration of stent patency. Fully covered self-expandable metal stents appear as a good alternative to plastic stents, since they have an increased radial diameter, longer stent patency, easier insertion technique and similar efficacy. Recent advances in endoscopic technique and various devices have allowed successful treatment in most cases. The development of novel endoscopic techniques and devices is still ongoing.

Outcomes of endoscopic management of primary and refractory postcholecystectomy biliary leaks in a multicentre review of 178 patients. BMC Gastroenterol 2015; 15:105. [PMID: 26285593 PMCID: PMC4545536 DOI: 10.1186/s12876-015-0334-y] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2015] [Accepted: 08/10/2015] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Biliary leaks have been treated with endoscopic management using different techniques with conflicting results. Furthermore the appropriate rescue therapy for refractory leaks has not been established. We evaluated the clinical effectiveness of initial endotherapy for postcholecystectomy biliary leaks using an homogenous approach (sphincterotomy + placement of a 10-French plastic stent) in a large series of patients as well as the optimal and efficacy of rescue endotherapy for refractory biliary leaks. METHODS This was a multicenter, retrospective study of 178 patients who underwent endoscopic management of postcholecystectomy biliary leaks with a combination of biliary sphincterotomy and the placement of a large-bore (10-French) plastic stent. Data were collected to analyze the clinical outcomes and technical success, efficacy of the rescue endotherapy and the need for surgery, adverse events and prognostic factors for clinical success of endotherapy. RESULTS Following endotherapy, closure of the leak was accomplished in 162/178 patients (91.0%). The multivariate logistic model showed that the type of leak, namely a high-grade biliary leak, was the only independent prognostic factor associated with treatment failure (OR = 26.78; 95% CI = 6.59-108.83; P < 0.01). The remaining 16 patients were treated with multiple plastic stents (MPSs) with a success rate of 62.5% (10 patients). The use of fewer than 3 plastic stents (P = 0.023) and a high-grade biliary leak (P = 0.034) were shown to be significant predictors of treatment failure with MPSs in refractory bile leaks. The 6 patients in whom the placement of MPSs failed were retreated with a fully cover self-expandable metallic stent (FCSEMS), resulting in closure of the leak in all cases. CONCLUSIONS Endotherapy of biliary leaks with a combination of biliary sphincterotomy and the placement of a large-bore plastic stent is associated with a high rate of success (90%). However in our series there were several failures using MPSs as a strategy for rescue endotherapy suggesting that refractory biliary leaks should be treated with FCSEMS especially in patients with high-grade leaks.

Abstract
BACKGROUND Endoscopic management of postcholecystectomy biliary leaks is widely accepted as the treatment of choice. However, refractory biliary leaks after a combination of biliary sphincterotomy and the placement of a large-bore (10F) plastic stent can occur, and the optimal rescue endotherapy for this situation is unclear. OBJECTIVE To compare the clinical effectiveness of the use of a fully covered self-expandable metal stent (FCSEMS) with the placement of multiple plastic stents (MPS) for the treatment of postcholecystectomy refractory biliary leaks. DESIGN Prospective study. SETTING Two tertiary-care referral academic centers and one general district hospital. PATIENTS Forty consecutive patients with refractory biliary leaks who underwent endoscopic management. INTERVENTIONS Temporary placement of MPS (n = 20) or FCSEMSs (n = 20). MAIN OUTCOME MEASUREMENTS Clinical outcomes of endotherapy as well as the technical success, adverse events, need for reinterventions, and prognostic factors for clinical success. RESULTS Endotherapy was possible in all patients. After endotherapy, closure of the leak was accomplished in 13 patients (65%) who received MPS and in 20 patients (100%) who received FCSEMSs (P = .004). The Kaplan-Meier (log-rank) leak-free survival analysis showed a statistically significant difference between the 2 patient populations (χ(2) [1] = 8.30; P < .01) in favor of the FCSEMS group. Use of <3 plastic stents (P = .024), a plastic stent diameter <20F (P = .006), and a high-grade biliary leak (P = .015) were shown to be significant predictors of treatment failure with MPS. The 7 patients in whom placement of MPS failed were retreated with FCSEMSs, resulting in closure of the leaks in all cases. LIMITATIONS Non-randomized design. CONCLUSION In our series, the results of the temporary placement of FCSEMSs for postcholecystectomy refractory biliary leaks were superior to those from the use of MPS. A randomized study is needed to confirm our results before further recommendations.

Abstract
BACKGROUND Covered self-expanding metal stents (CSEMS) are being increasingly used in the endoscopic treatment of benign biliary strictures (BBS). There is no solid evidence yet to support their routine use. GOALS To evaluate feasibility, success rate, and complications of CSEMS compared with multiple plastic stents (PS) in BBS in a systematic review. STUDY A systematic search of electronic databases (Medline, Scopus, and Embase) for studies published from 2000 to 2012 combined to hand-search of reference lists resulted 4977 articles. Out of 99 potentially relevant studies selected for full-text review, 12 CSEMS (376 patients) and 13 PS studies (570 patients) met the final inclusion criteria. A systematic review comparing the 2 methods was made using proportion meta-analysis. RESULTS A tendency to successful use of CSEMS in strictures related to chronic pancreatitis (CP) was shown: clinical success of 77% and 33% [95% confidence interval (CI), 61%-94% vs. 4%-63%, P=0.06] was achieved with CSEMS and PS at 12 months follow-up, respectively. There were no differences in the success rates of other etiologies except CP or in the early complications. In CSEMS, incidence of late adverse events was lower in CP-related strictures (3% vs. 67%, 95% CI, 0%-13% vs. 17%-99%, P=0.02). The median number of endoscopic retrograde cholangiopancreatographies was lower with CSEMSs: 1.5 versus 3.9 (P=0.002). CONCLUSIONS Improved clinical success with fewer endoscopic sessions and corresponding complication rate may be achieved with CSEMS treatment compared with PS in BBS secondary to CP. In other BBS etiologies, this systematic review remains inconclusive.

Abstract
BACKGROUND Endotherapy of postcholecystectomy bile duct stricture (PCBS) has been established as an alternative treatment to surgery. Several studies have reported conflicting results regarding the predictors of success or failure of endotherapy. OBJECTIVE To evaluate the different cholangioscopic appearances of PCBS after endotherapy with an increasing number of plastic stents and the predictive values of these appearances for the outcome. DESIGN Prospective study with a long-term follow-up. SETTING Two academic tertiary referral centers. PATIENTS Twenty consecutive patients with major bile duct injury, with a bile leak, and a PCBS who underwent therapeutic ERCP. INTERVENTIONS Closure of the leak followed by temporary placement of multiple plastic stents for the treatment of PCBS, followed by cholangioscopy at the end of endotherapy. MAIN OUTCOME MEASUREMENTS To analyze the predictive value of cholangioscopy, other predictors of stricture recurrence after endotherapy, and long-term clinical success. RESULTS Closure of the leak was achieved in all patients. The median duration of endotherapy was 12 months (range 7-18 months). After endoscopic stenting, the PCBS was considered to be appropriately dilated in all patients. After endotherapy, 3 different findings were noted on cholangioscopy: (1) no lesion or minor defect (n = 10), (2) minor stricture with a fibrous ring (n = 6), and (3) presence of tissue hyperplasia (n = 4). During follow-up, stricture recurrence developed in 4 of 20 patients. All 4 patients were successfully retreated by an additional period of stenting and remained free of cholestasis after a median follow-up period of 44 months. By Kaplan-Meier (log-rank) and univariate analyses, the cholangioscopic pattern of tissue hyperplasia was significantly associated with stricture recurrence (P < .01). LIMITATIONS Small sample size. CONCLUSIONS Endoscopic stenting should be regarded as the primary treatment of choice because of the successful long-term outcome after 1 or more additional periods of treatment. However, the cholangioscopic pattern of tissue hyperplasia at the time of stent removal is a strong predictor of stricture recurrence, and this observation may lead to an additional period of endotherapy or other treatment modalities.

Abstract
Biliary stents are widely used not only for palliative treatment of malignant biliary obstruction but also for benign biliary diseases. Each plastic stent or self-expandable metal stent (SEMS) has its own advantages, and a proper stent should be selected carefully for individual condition. To compensate and overcome several drawbacks of SEMS, functional self-expandable metal stent (FSEMS) has been developed with much progress so far. This article looks into the outcomes and defects of each stent type for benign biliary stricture and describes newly introduced FSEMSs according to their functional categories.

Abstract
The diagnosis and the treatment of dominant strictures (DS) in patients with primary sclerosing cholangitis (PSC) is challenging and the scientific literature on the subject is quite limited. Only level II and level III evidence is available to guide physicians managing patients with DS and PSC. For the diagnosis, intraductal endoscopic ultrasound is the most sensitive (64%) and specific (95%) test. However, the majority of cases require a combination of several different diagnostic tests, as there is no single investigation that can rule out malignancy in this group of patients. For the treatment, serial endoscopic or percutaneous dilatations provide 1- and 3-year biliary duct patency in 80 and 60% of patients, respectively. Dilatation and stenting are the most common interventions, although the optimal duration of treatment has still not been clearly defined. Bile duct resection and/or bilioenteric bypass are currently indicated only for patients with preserved liver function. For all other patients, benign DS can be treated with endoscopic dilatation with short-term stenting. This approach is effective and safe and does not increase the risk of malignant transformation or complications for liver transplant candidates. During the last decade, the use of self-expandable metallic stents for benign diseases has become an innovative option. The aim of this article is to review the diagnostic and therapeutic strategies for patients affected by PSC and DS with specific emphasis on the outcomes of patients treated with temporary stents.

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 AND OBJECTIVE An animal model for bile duct stenosis using intraductal thermal injury has not yet been established. The aims of the current study were to develop biliary stenosis in a swine model by inducing intraductal thermal injury using a heat probe or radiofrequency ablation electrode and to investigate an effective and safe energy dose. METHODS Intraluminal thermal injury was applied to the common bile duct with a heat probe in three swines and a radiofrequency ablation electrode in the other three swines by either endoscopic retrograde cholangiography or open laparotomy. Cholangiography and histologic evaluation of common bile duct were taken 2 weeks after thermal injury. RESULTS Thermal injury with a heat probe at 25 J for 40 seconds produced a stricture in all three animals. Application of a radiofrequency ablation electrode produced a stricture in two of three animals. An energy dose of 40 W at 80°C for 30 seconds produced biliary stenosis without any complications initially and 2 weeks after thermal injury. CONCLUSIONS The application of a heat probe and a radiofrequency ablation electrode for intraductal thermal injury resulted in a reproducible animal model of biliary stenosis.

Abstract
Endoscopic therapy by balloon dilation and placement of multiple large-bore plastic stents is the treatment of choice for benign biliary stricture. This approach is effective but it typically requires multiple endoscopic sessions given the short duration of stent patency. The endoscopic approach for treatment of bile leak involves the placement of a stent with or without biliary sphincterotomy. The self-expandable metal stent (SEMS) has traditionally been used for palliation of malignant biliary strictures given the long duration of stent patency owing to their larger stent diameter. Recently, SEMS has been used in a variety of benign biliary strictures and leaks, especially with the design of the covered self-expandable metal stent (CSEMS), which permits endoscopic-mediated stent removal. The use of CSEMS in benign biliary stricture could potentially result in a decrease in endoscopic sessions and it is technically easier when compared to placement of multiple plastic stents. However, complications such as cholecystitis due to blockage of cystic duct, stent migration, infection and pancreatitis have been reported. The potential subsegmental occlusion of contralateral intrahepatic ducts also limits the use of CSEMS in hilar stricture. Certain techniques and improvement of stent design may overcome these challenges in the future. Thus, CSEMS may be appropriate in only highly selected conditions, such as refractory benign biliary stricture, despite multiple plastic stent placement or difficult to treat bile duct stricture from chronic pancreatitis, and should not be used routinely. This review focuses on the use of fully covered self-expandable metal stent for benign biliary strictures and bile leaks.
