Abstract
The last decades have brought impressive advances in liver transplantation. As a result, there was a notable rise in the number of liver transplants globally. Advances in surgical techniques, immunosuppressive therapies and radiologically guided treatments have led to an improvement in the prognosis of these patients. However, the risk of complications remains significant, and the management of liver transplant patients requires multidisciplinary teams. The most frequent and severe complications are biliary and vascular complications. Compared to vascular complications, biliary complications have higher incidence rates but a better prognosis. The early diagnosis and selection of the optimal treatment are crucial to avoid the loss of the graft and even the death of the patient. The development of minimally invasive techniques prevents surgical reinterventions with their associated risks. Liver retransplantation remains the last therapeutic solution for graft dysfunction, one of the main problems, in this case, being the low number of donors.

Abstract
Objectives Anastomotic biliary strictures (ABSs) are common complications following living donor liver transplantation (LDLT). We evaluated the feasibility of a novel removable, intraductal, fully covered, self‐expandable metallic stent (FCSEMS) for the treatment of ABSs following LDLT. Methods Nine patients with duct‐to‐duct ABSs that developed following LDLT were prospectively enrolled in this study. We placed a short FCSEMS with a long lasso and middle waist formation in each patient's ABS above the papilla and removed it 16 weeks later. Results The FCSEMS placements were successful in all nine cases. Four patients experienced mild cholangitis, which was resolved with conservative treatment. Additionally, there was one case of distal migration. The FCSEMSs were successfully removed from all the patients, and the clinical success rate was 100%. Stricture recurrence occurred in one (11.1%) patient during the follow‐up period. Limitations The small number and lack of comparison with other types of FCSEMSs and plastic stents. Conclusions Intraductal placement of FCSEMSs is useful for treating refractory ABSs after LDLT, although further studies are required with larger sample sizes.

Abstract
A biliary stricture is an abnormal narrowing in the ductal drainage system of the liver that can result in clinically and physiologically relevant obstruction to the flow of bile. The most common and ominous etiology is malignancy, underscoring the importance of a high index of suspicion in the evaluation of this condition. The goals of care in patients with a biliary stricture are confirming or excluding malignancy (diagnosis) and reestablishing flow of bile to the duodenum (drainage); the approach to diagnosis and drainage varies according to anatomic location (extrahepatic vs perihilar). For extrahepatic strictures, endoscopic ultrasound-guided tissue acquisition is highly accurate and has become the diagnostic mainstay. In contrast, the diagnosis of perihilar strictures remains a challenge. Similarly, the drainage of extrahepatic strictures tends to be more straightforward and safer and less controversial than that of perihilar strictures. Recent evidence has provided some clarity in multiple important areas pertaining to biliary strictures, whereas several remaining controversies require additional research. The goal of this guideline is to provide practicing clinicians with the most evidence-based guidance on the approach to patients with extrahepatic and perihilar strictures, focusing on diagnosis and drainage.

Abstract
Abnormal liver tests are common after liver transplantation. The differential diagnosis depends on the clinical context, particularly the time course, pattern and degree of elevation, and donor and recipient factors. The perioperative period has distinct causes compared with months and years after transplant, including ischemia-reperfusion injury, vascular thrombosis, and primary graft nonfunction. Etiologies seen beyond the perioperative period include biliary complications, rejection, infection, recurrent disease, and non-transplant-specific causes. The evaluation begins with a liver ultrasound with Doppler as well as appropriate laboratory testing and culminates in a liver biopsy if the imaging and laboratory testing is unrevealing.

Abstract
BACKGROUND AND AIMS Biliary strictures after liver transplantation are associated with significant morbidity and mortality. Although various endoscopic treatment strategies are available, consensus on a particular strategy is lacking. Moreover, the influence of endoscopic therapy on overall survival has not been studied. This retrospective study aimed to evaluate the impact of scheduled endoscopic dilatation of biliary strictures after orthotopic liver transplantation on therapeutic success, adverse events, and survival. METHODS Between 2000 and 2016, patients with post-transplant anastomotic and nonanastomotic strictures were treated with balloon dilatation at defined intervals until morphologic resolution and clinical improvement. The primary clinical endpoint was overall survival, whereas secondary outcomes were technical and sustained clinical success, adverse events, treatment failure, and recurrence. RESULTS Overall, 165 patients with a mean follow-up of 8 years were included; anastomotic and nonanastomotic strictures were diagnosed in 110 and 55 patients, respectively. Overall survival was significantly higher in patients with anastomotic strictures than in those with nonanastomotic strictures (median, 17.6 vs 13.9 years; log-rank: P < .05). Sustained clinical success could be achieved significantly more frequently in patients with anastomotic strictures (79.1% vs 54.5%, P < .001), and such patients showed significantly superior overall survival (19.7 vs 7.7 years; log-rank: P < .001). Sustained clinical success and the presence of nonanastomotic strictures were independently associated with better and worse outcomes (P < .05), respectively. CONCLUSIONS Scheduled endoscopic treatment of biliary anastomotic and nonanastomotic strictures after liver transplantation is effective and safe, with high success rates. The implementation of this strategy controls symptoms and significantly improves survival.

Abstract
INTRODUCTION The occurrence of anastomotic biliary stricture (BS) remains an essential issue following liver transplantation (LT). The present study aimed to compare our findings regarding the incidence of anastomotic BS to what is known. METHODS The present study is a single-center, retrospective cohort study of a total number of 717 consecutive patients (426 men and 291 women) who had undergone LT from January 2001 to March 2016. Multivariable Cox regression analysis was conducted to evaluate the risk factors associated with anastomotic BS development. RESULTS Post-transplant anastomotic BS developed in 70 patients (9.8%). In the Cox multivariate analysis (a stepwise forward conditional method), factors including biliary leak (hazard ratio [HR]: 6.61, 95% confidence interval [CI]: 3.08-17.58, p < 0.001), hepatic artery thrombosis (HR: 2.29, 95% CI: 1.03-5.88; p = 0.003), and acute rejection (HR: 2.18, 95% CI: 1.16-3.37; p = 0.006) were identified as independent risk factors for the development of anastomotic BS. Surgery in 6 cases (66.7%), followed by endoscopic retrograde cholangiopancreatography (ECRP) with a metal stent in 18 cases (62.1%), percutaneous transhepatic biliary drainage in 9 (20.9%), and ERCP with a single plastic stent in 8 (18.2%), had the highest effectiveness rates in the management of BS, respectively. CONCLUSIONS Risk factors including biliary leak, hepatic artery thrombosis, and acute rejection were independently associated with an anastomotic BS. ERCP with a metal stent may be considered as an effective treatment procedure with a relatively low complication rate in the management of benign post-LT anastomotic BS.

Abstract
BACKGROUND Endoscopic biliary stenting (EBS) with a fully covered, self-expandable metallic stent (FC-SEMS) and plastic stent (PS) is safe and efficient for biliary anastomotic strictures (ASs) after a deceased donor liver transplantation. Limited studies have investigated the use of FC-SEMSs for biliary strictures post-living donor liver transplantation (LDLT). We compared the resolution rate of biliary ASs post-LDLT and the 12-month recurrence rates post-stent removal between EBS with an FC-SEMS, PS, and percutaneous transhepatic biliary drainage (PTBD). METHODS Patients with biliary ASs after an LDLT (mean age: 57.3 years, 76.1% men) hospitalized between 2014 and 2017 were enrolled. Endoscopic retrograde cholangiopancreatography (ERCP) was repeated every 3-4 months. Patients were followed-up for at least 1-year post-stent removal. RESULTS Of the 75 patients enrolled, 16, 20, and 39 underwent EBS with an FC-SEMS, PS, and PTBD, respectively. Median follow-up period was 39.2 months. Fewer ERCP procedures were needed in the FC-SEMS group than in the PS group (median, 2 vs. 3; P = 0.20). Median stent indwelling periods were 4.7, 9.3, and 5.4 months in the FC-SEMS, PS, and PTBD groups, respectively (P = 0.006). The functional resolution rate was lower in the PS group (16/20) than in the FC-SEMS (16/16) or PTBD (39/39) group (P = 0.005). The radiologic resolution rate was higher in the FC-SEMS group (16/16) than in the PS group (14/20) (P = 0.07). The 12-month recurrence rates showed no significant differences (FC-SEMS, 4/16; PS, 3/16; PTBD, 6/39; P = 0.66). The rates of complications during treatment differed significantly between the groups (P = 0.04). Stent migration occurred in 1 (6.3%) and 5 (25.0%) patients in the FC-SEMS and PS groups, respectively (P = 0.59). CONCLUSIONS EBS with an FC-SEMS is comparable with EBS with a PS or PTBD in terms of biliary stricture resolution and 12-month recurrence rates. The use of FC-SEMSs is potentially effective and safe for biliary AS resolution after LDLT.

Abstract
BACKGROUND Anastomotic bile duct stricture (ABS) is one of the most common complications after liver transplantation. Current practice of endoscopic retrograde cholangiopancreatography (ERCP) with multiple plastic stent (MPS) insertion often requires multiple sessions before achieving stricture resolution. We aimed to compare the efficacy of fully covered self-expandable metallic stent (FCSEMS) with MPS method while simultaneously analyzing the relative healthcare cost between the two methods in the management of ABS. METHODS Liver transplant patients with ABS who received ERCP with stent placement were identified by query of our endoscopic database. Comparative analyses between the group of patients treated with ERCP with MPS and the group treated with FCSEMS were performed. The costs to achieve stricture resolution, and the rates of stricture resolution, recurrence and complications were also compared. RESULTS A total of 158 patients underwent ERCP with stent insertion for the management of ABS. Of those, 49 patient received FCSEMS for their ABS while 109 patients were treated with MPS only. Our cost analysis showed early utilization of FCSEMS can deliver up to 25% savings in the total procedure cost while providing comparable rates of stricture resolution. The rates of technical success, stricture recurrence and adverse outcomes, and stricture free durations were also comparable between the two groups. CONCLUSION While providing efficacy and safety rates comparable to ERCP-MPS, the incorporation of FCSEMS at early stage of ABS management could provide a substantial savings by reducing the number of ERCP session to achieve stricture resolution. Optimization of the timing and duration of FCSEMS indwelling time needs further validation.

Abstract
Cholangiopathies describe a group of conditions affecting the intrahepatic and extrahepatic biliary tree. Impairment to bile flow and chronic cholestasis cause biliary inflammation, which leads to more permanent damage such as destruction of the small bile ducts (ductopaenia) and biliary cirrhosis. Most cholangiopathies are progressive and cause end-stage liver disease unless the physical obstruction to biliary flow can be reversed. This review considers large-duct cholangiopathies, such as primary sclerosing cholangitis, ischaemic cholangiopathy, portal biliopathy, recurrent pyogenic cholangitis and Caroli disease.

Abstract
Background Anastomotic biliary strictures (ABS) following liver transplantation (LT) are one of the most common complications, occurring in 4.5-32% of patients. Multiple plastic stenting (MPS) requires multiple sessions, with the associated risk, cost and patient discomfort. Fully covered self-expandable metal stents (FC-SEMS) have increasingly been used in this setting. We performed a systematic review and meta-analysis of randomized controlled trials (RCTs), comparing the role of FC-SEMS and MPS in the treatment of ABS post-LT. Methods We conducted a bibliographic search using PubMed and EMBASE, aimed at identifying available RCTs that compared MPS to FC-SEMS in patients with ABS post LT from January 2000 to October 2017. Primary outcomes were ABS resolution and recurrence, while secondary outcomes were adverse events and number of procedures performed. Pooled estimates were calculated using random-effects models. Results Four RCTs (205 patients) were included. ABS resolution and recurrence did not differ significantly between the groups (odds ratio [OR] 1.05, 95% confidence interval [CI] 0.43-2.56, P=0.92; and OR 2.37, 95%CI 0.54-10.38, P=0.25). The same was true for adverse events (OR 0.91, 95%CI 0.84-3.48, P=0.86) and migration rate (OR 1.31, 95%CI 0.46-3.71, P=0.61). The mean number of endoscopic retrograde cholangiopancreatography procedures was lower for FC-SEMS (mean difference [MD] -2.08). Conclusions FC-SEMS and MPS had equal ABS resolution and recurrence, although there was a trend towards a higher recurrence rate in FC-SEMS that disappeared when trials with a shorter stent indwelling time were excluding. No difference was found in overall adverse events or migration rate.

The most widely used technique is placement of multiple plastic stents, but discussions are ongoing on the benefits of fully-covered self-expandable metallic stents (FCEMS) in this situation. This study aimed to compare results from use of plastic and metal stents to treat biliary stricture after transplantation. Patients and methods Searches were performed in the Medline, EMBASE, SciELO/LILACS, and Cochrane databases, and only randomized studies comparing the two techniques were included in the meta-analysis. Results Our study included four randomized clinical trials totaling 205 patients. No difference was observed between the stricture resolution rate (RD: 0.01; 95 %CI [-0.08 - 0.10]), stricture recurrence (RD: 0.13; 95 %CI [-0.03 - 0.28]), and adverse events (RD: -0.10; 95 %CI [-0.65 - 0.44]) between the plastic and metallic stent groups. The metallic stent group demonstrated benefits in relation to the number of ERCPs performed (MD: -1.86; 95 %CI [-3.12 to -0.6]), duration of treatment (MD: -105.07; 95 %CI [-202.38 to -7.76 days]), number of stents used (MD: -10.633; 95 %CI [-20.82 to -0.44]), and cost (average $ 8,288.50 versus $ 18,580.00, P < 0.001). Conclusions Rates of resolution and recurrence of stricture are similar, whereas the number of ERCPs performed, number of stents used, duration of treatment, and costs were lower in patients treated with FCEMS, which shows that this device is a valid option for initial treatment of post-OLTX biliary stricture.

Abstract
BACKGROUND Standard methods for endoscopic retrograde cholangiopancreatography (ERCP) management of anastomotic strictures (AS) after OLT includes repeated balloon dilation of the stricture with subsequent insertion of a plastic biliary stent (PBS). In post-OLT patients not responding to standard endoscopic treatment, the placement of fully covered self-expanding metal stents (FCSEMS) is a valid alternative to surgical treatment. The aim of this study was to compare the results of new FCSEMS implantation with the standard ERCP stricture management protocol and with conventional FCSEMS insertion. MATERIAL AND METHODS This retrospective study involved 39 post-OLT patients with confirmed diagnosis of biliary AS. Enrolled subjects were divided into 2 groups: the FCSEMS group (study group) and the PBS group (control group). The study group was divided into 2 subgroups: the conventional FCSEMS group and the new-type FCSEMS group. RESULTS Stricture recurrence after PBS placement was observed in 36.36% of controls and in only 9.52% of study group members (P=0.170). Recurrence rates in patients after conventional FCSEMS and new type FCSEMS implantation was similar (10% vs. 9.09%; P=0.501). The applied treatment was successful in 82.61% of study group members and only 43.75% of controls (P=0.029). Success rates of conventional FCSEMS and new-type SEMS insertion did not differ significantly (81.82% vs. 83.33%, P=0.649). There was no statistically significant difference in complication rates between groups (P=0.879). CONCLUSIONS Implantation of FCSEMS is more effective than repeated balloon dilatation of AS with subsequent PBS placement and is they have similar complication rates. Application of new-type FCSEMS gives results comparable to conventional FCSEMS.

Abstract
BACKGROUND AND AIMS Treatment of anastomotic biliary strictures (ABSs) after orthotopic liver transplantation by endoscopic insertion of multiple plastic stents (MPSs) is well established. The use of covered self-expandable metal stents (cSEMSs) for this indication is less investigated. METHODS In an open-label, multicenter, randomized trial, patients with confirmed ABSs were randomly assigned 1:1 to receive either an MPS or a cSEMS. The primary endpoint was the number of endoscopic interventions until ABS resolution. Secondary endpoints were frequency of adverse events, treatment success rates, and time to treatment success and recurrence of ABS during follow-up of at least 1 year. RESULTS Fifty-eight patients were included between 2012 and 2015, and 48 patients completed follow-up. Patients receiving MPS (n = 24) underwent a median of 4 (range, 3-12) endoscopic retrograde cholangiography examinations, whereas those in the cSEMS group (n = 24) underwent a median of 2 (range, 2-12) sessions until ABS resolution (P < .001). A median of 8 (range, 2-32) stents was used until ABS resolution within the MPS group and 1 (range, 1-24) in the cSEMS group (P < .0001). cSEMS migration occurred in 8 (33.3%) patients. Treatment duration did not differ significantly. Initial treatment success rates were high with 23 (95.8%) in the MPS group and 24 (100%) for cSEMSs (P = 1). Five (20.8%) patients in both groups showed stricture recurrence after a median follow-up of 500 days (range, 48-1317 days). CONCLUSIONS cSEMSs for treatment of ABSs needed less endoscopic interventions to achieve similar efficacy as MPS and might become a new treatment standard. However, the optimal duration of cSEMS therapy and cost-efficacy have to be evaluated. (Clinical trial registration number: NCT01393067.).

Abstract
Anastomotic biliary strictures (ABSs) occur in up to 15% of patients after liver transplantation (LT). The aim of this study was to compare the efficacy and safety of self-expandable metal stents (SEMS) versus multiple plastic stents (MPS). Databases were searched through April 2017. The outcome measures were technical success, stricture resolution, recurrence and complications. We synthesized the findings descriptively and performed a meta-analysis. Three randomized controlled trials and one retrospective cohort study were identified, including 179 MPS and 119 SEMS patients. Outcome data were pooled in a meta-analysis that showed an advantage of SEMS in terms of the number of ERCP procedures (mean difference: 1.69 ERCP; 95% CI, 1-2.39; P < 0.00001) and treatment days (mean difference: 40.2 days; 95% CI, 3.9-76.4; P = 0.03), with no differences in terms of ABS resolution or recurrence. Fourteen case series reported MPS outcomes and fifteen reported SEMS outcomes, including 647 and 419 patients, respectively. Based on low-quality evidence, we cannot draw any reliable conclusions on the superiority of MPS or SEMS strategies. Even though shorter treatment times and fewer ERCP procedures support the use of SEMS, whether one technique has well-defined advantages over the other remains unclear.

Abstract
BACKGROUND & AIMS Anastomotic bile duct stricture (ABS) remains as one of the most common complications in liver transplant patients. Current practice of endoscopic retrograde cholangiopancreatography (ERCP) with insertion of plastic stent often requires multiple procedures before achieving stricture resolution. To date, studies using covered self-expandable metallic stent (cSEMS) in ABS management reported varying degrees of efficacy. The aim of this study was to analyze long-term efficacy of cSEMS in patients with ABS and identify factor(s) influencing the probability of stricture resolution. METHODS Liver transplant patients with ABS who received cSEMS were identified by query of our endoscopic database. The rate of stricture resolution, duration of stricture-free interval, factors associated with stricture resolution, and adverse outcomes were analyzed. RESULTS Among 44 liver transplant patients with refractory ABS who underwent ERCP-cSEMS, stricture resolution was observed in 33 patients (75%). Longer duration of cSEMS insertion was the only variable associated with increasing probability of stricture resolution. There was 20% increase in odds of stricture resolution for every additional week cSEMS was in place. Among 33 patients with initial stricture resolution, 26 patients (78.8%) maintained bile duct patency throughout the follow-up period. The most common adverse outcome was internal migration of cSEMS, which occurred in 11 patients (25%). CONCLUSIONS The rate of ABS resolution observed with cSEMS placement in a single ERCP session appears to be comparable with that of multiple ERCPs with plastic stent placement reported previously. Longer stent insertion period is associated with higher likelihood of ABS resolution.

Abstract
INTRODUCTION Orthotopic liver transplantation anastomotic biliary strictures (OLT ABS) are managed with endoscopic biliary stent therapy but the recurrence rate is substantial. Our aims were to retrospectively determine the recurrence rates of OLT ABS after initial successful stent therapy, characterize the management of recurrences and identify associated variables. MATERIALS AND METHODS Clinical data from 943 patients receiving non-living donor OLT at our institution from 2005-2012 were reviewed, and 123 OLT ABS patients receiving stent therapy were identified. Features of their endoscopic stent therapy and other pertinent clinical information were evaluated. RESULTS ABS recurred in 25.5% of patients (24/94) after an initial successful course of stent therapy. Recurrences were received a second course of endoscopic stent therapy and 67% of patients (16/24) achieved long-term remediation of ABS. Six patients underwent a third course of endoscopic stent therapy with 4 patients achieving remediation. Overall remediation rate among ABS recurrences was 83.3% (20/24). A bivariate comparison demonstrated HCV infection, age, median months of maximal stenting and a lower maximum cumulative stent diameter were risk factors for ABS recurrence. Using a Cox regression model, only HCV status proved to be a risk factor for recurrence. DISCUSSION In conclusion repeat stent therapy achieved high stricture remediation rates. Recurrence after the first or even second course of stenting should not imply failure of endoscopic therapy. A positive HCV status may be associated with higher stricture recurrence rates and this association should be further investigated.

Abstract
OBJECTIVE The aim of this work was to evaluate the safety and efficacy of a fully covered self-expandable metal stent (FCSEMS) in the treatment of post-liver transplantation biliary strictures. METHODS From October 2009 to October 2014, 44 patients with post-liver transplantation biliary stenosis were treated with the use of endoscopic retrograde cholangiography and placement of FCSEMS after informed consent. The FCSEMS was scheduled to remain in situ for 3-6 months. Patients were followed at regular intervals to evaluate for symptoms and liver function tests. Technical success, complications, and patient outcome were analyzed. RESULTS All of the strictures were anastomotic, 52% having occurred within the 1st year following the transplantation. Placement of the FCSEMS was possible on the 1st attempt in 54% of patients. Stricture resolution at the time of stent removal was seen in 100% of the cases. During an average follow-up of 27.83 ± 18.3 months after stent removal, stenosis recurred in 9 out of 41 patients (21.9%). The average time of recurrence was 11.78 ± 13.3 months. In all of these cases, the recurrence was resolved by means of placement of another FCSEMS. In 4 cases, the recurrence was associated with a migration of the prosthesis, partial in 2 cases and total in 2 cases. Stent migration occurred in a total of 17 of the 41 patients (41.4%), in 13 of the 32 (40.6%) who had no recurrence of stenosis and in 4 of the 9 (44.4%) of those who experienced recurrence. The average numbers of endoscopic retrograde cholangiography studies required per patient were 2.8 in those with no recurrence and 3.3 in those with recurrence. No death was associated with the process. CONCLUSIONS FCSEMS is a safe effective alternative to plastic stents in the treatment of post-transplantation biliary strictures, resulting in a lower risk of complications and better patient acceptance.

Abstract
BACKGROUND Recently, there has been an increase in clinical success rates using nonsurgical methods to resolve anastomotic biliary strictures (ABSs) that develop after liver transplantation (LT). However, some strictures are particularly refractory and cannot be completely resolved by an endoscopic or percutaneous procedure. Consequently, the aim of this study was to examine the feasibility and efficacy of using a newly designed fully covered self-expandable metal stent (FCSEMS) to resolve refractory ABS. METHODS A total of 35 patients with an ABS that developed after LT, but could not be resolved by an endoscopic or percutaneous procedure, were included in this study. FCSEMSs were positioned endoscopically and removed after 2-3 months. After stent removal, the patients were followed to assess complications, including re-stenosis. RESULTS The mean period from LT to stricture was 13.7 months, and the mean duration of the stricture was 31.8 months. The type and mean number of procedures previously attempted were endoscopic retrograde cholangiopancreatography (ERCP) (9.1 ± 5.1) in 19 patients and percutaneous transhepatic biliary drainage (9.2 ± 4.8) in 16 patients. All patients had successful FCSEMS insertions and removals; the mean stent indwelling time was 3.2 months. The mean follow-up period was 18.7 months (range: 6.4-37.8 months). Stricture recurrence was observed in 6 of 29 patients (recurrence rate: 20.7%). The anastomotic stricture resolved with the FCSEMS insertion in 29 of 35 patients (clinical success rate: 82.9%). CONCLUSIONS The newly designed FCSEMS is a potentially feasible and effective treatment for anastomotic strictures that develop after LT but are not amenable to treatment by conventional procedures.

Abstract
BACKGROUND AND AIMS Biliary complications (BCs) occur in up to 40% of living donor liver transplant (LDLT) recipients. The aim of this study was to evaluate the efficacy of endoscopic therapy in the management of LDLT-related BCs. METHODS A retrospective study of 100 LDLT recipients at a single transplant center over a 9-year period was conducted. BC was defined as a biliary leak and/or a stricture. Patient records were used to identify time to diagnosis, type of intervention, and time to resolution. RESULTS BCs occurred in 46 (46%) patients; median follow-up was 4.6 years (range 5 days-9.3 years); and median time to diagnosis was 37.5 days (range 1 day-3.5 years). BCs were classified as a leak in 6 (6%), stricture in 22 (22%), and a leak + stricture in 18 (18%). ERCP was the initial treatment modality in 43/46 (93%) patients and was completed in 42/43 (98%). Three (6.5%) patients with a leak underwent surgery as the primary treatment approach. The median time to resolution of BCs was 91.5 days (range 21-367). Thirteen patients had a recurrence which was managed with endoscopic therapy alone. CONCLUSIONS Endoscopic therapy was successful in almost all patients (98%) and ERCP alone resulted in successful treatment in a higher proportion of patients (93%) than traditionally reported. Advanced endoscopic techniques obviate the need for PTC and/or surgery and allow successful management in almost all LDLT recipients presenting with BC and in patients with recurrence of strictures.

Abstract
The most common biliary complication after liver transplantation is anastomotic stricture (AS) and it can occur isolated or in combination with other complications. Liver graft from a cadaveric donor or a living donor has an influence on the incidence of biliary strictures as well as on the response to endoscopic treatment. Endoscopic treatment using balloon dilation and insertion of biliary stents by endoscopic retrograde cholangiopancreatography (ERCP) is the initial approach to these complications. AIM The aim of this article is to compare different endoscopic techniques to treat post-liver transplantation biliary strictures. METHODS The search was carried out on MEDLINE, EMBASE, Scielo-LILACS and Cochrane Library databases through June 2015. A total of 1100 articles were retrieved. Ten clinical trials were analyzed, and seven were included in the meta-analysis. CONCLUSIONS The endoscopic treatment of AS was equally effective when compared the use of fully covered self-expandable metal stents (FCSEMS) vs. plastic stents, but the use of FCSEMS was associated with a lower complication risk. The treatment of AS with balloon dilation or balloon dilation associated with plastic stents presented similar results. Deceased donor liver transplantation reduced the risk of biliary stenosis and the endoscopic treatment in these patients was more effective when compared with Living donor liver transplantation.

Abstract
Endoscopic treatment of biliary strictures involving plastic stent placement has been used widely. The use of self-expandable metal stents (SEMSs) has been described for anastomotic strictures following liver transplantation (LT). This review aimed to assess and compare the efficacy of plastic stents with SEMS in LT patients. Information was retrieved regarding technical success, stricture resolution, the number of endoscopic retrograde cholangiography procedures, follow-up, immediate, and late complications. Eight studies involving plastic stents had a stricture resolution rate of 84.5%, with the rates ranging from 63% to 100%. These rates are comparable with the stricture resolution rate of 75% determined from six studies that involved 236 patients who received metal stents and the rates ranged from 53% to 81%. The observed success rate for metal stents used to manage post-LT anastomotic biliary strictures was below the reported rate for multiple plastic stents. Hence, the currently available metal stents should not be offered for the management of post-LT anastomotic biliary strictures.

Abstract
The use of octogenarian donors to increase the donor pool in liver transplantation (LT) is controversial because advanced donor age is associated with a higher risk of ischemic-type biliary lesions (ITBL). The aim of this study was to investigate retrospectively the role of a number of different pre-LT risk factors for ITBL in a selected population of recipients of octogenarian donor grafts. Between January 2003 and December 2013, 123 patients underwent transplantation at our institution with deceased donor grafts from donors of age ≥80 years. Patients were divided into 2 groups based on the presence of ITBL in the posttransplant course. Exclusion criteria were retransplantations, presence of vascular complications, and no availability of procurement liver biopsy. A total of 88 primary LTs were included, 73 (83.0%) with no posttransplant ITBLs and 15 (17.0%) with ITBLs. The median follow-up after LT was 2.1 years (range, 0.7-5.4 years). At multivariate analysis, donor hemodynamic instability (hazard ratio [HR], 7.6; P = 0.005), donor diabetes mellitus (HR, 9.5; P = 0.009), and donor age-Model for End-Stage Liver Disease (HR, 1.0; P = 0.04) were risk factors for ITBL. Transplantation of liver grafts from donors of age ≥80 years is associated with a higher risk for ITBL. However, favorable results can be achieved with accurate donor selection. Donor hemodynamic instability, a donor history of diabetes mellitus, and allocation to higher Model for End-Stage Liver Disease score recipient all increase the risk of ITBL and are associated with worse graft survival when octogenarian donors are used.

No Distal Migration in Unfixed Versus Fixed Cell Structure Covered Self-Expanding Metal Stents for Treatment of Benign Biliary Disease. Dig Dis Sci 2015; 60:2495-501. [PMID: 25868631 DOI: 10.1007/s10620-015-3656-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2014] [Accepted: 04/01/2015] [Indexed: 01/18/2023]
Abstract
BACKGROUND Fully covered self-expandable metal stents (FCSEMS) are increasingly used for treatment of benign common bile duct (CBD) stricture or leakage, but dislodgement of FCSEMS is frequent. AIMS To compare dislocation rate and clinical outcome of a standard fixed cell structure FCSEMS (S-FCSEMS) to a novel FCSEMS with an unfixed cell structure (N-FCSEMS). METHODS We performed a retrospective analysis of all patients with FCSEMS insertion for benign biliary disease at our Hospital from 03/2008 to 03/2014. Both stent types N-FCSEMS and S-FCSEMS were applied as available unrelated to the indication. RESULTS Twenty-nine patients (S-FCSEMS: 18, N-FCSEMS: 11) were included. Stent placement was technically successful in 28/29 (96.6 %) patients; stent removal was successful in 26/27 (96.2 %). Two patients with N-FCSEMS were excluded due to unsuccessful placement and withdrawal of consent for stent removal, respectively. Stent migration into the duodenum (distal migration) was observed in 9/18 (50 %) in the S-FCSEMS group compared to 0/9 in the N-FCSEMS (p < 0.005). FCSEMS migration into the CBD (proximal migration) was found in 2/18 (11 %, S-FCSEMS) versus 2/9 (22 %, N-FCSEMS, p = 0.514). A foreshortening of the N-FCSEMS occurred in 3/9 patients (33 %) compared to 0/18 S-FCSEMS (p = 0.08). Clinical resolution of the treated CBD-disease was observed in 5/9 (56 %, N-FCSEMS) versus 12/18 (67 %, S-FCSEMS) at the time of stent removal (p = 0.604) and in 0/9 and 10/18 (56 %) cases during follow-up, respectively (p < 0.005). CONCLUSION An unfixed cell structure of FCSEMS seems to prevent distal migration, but proximal migration still occurs and foreshortening of the N-FCSEMS constrains clinical outcome.

Abstract
Biliary complications after liver transplantation (LT) are an important cause of morbidity and mortality. In most cases, an anastomosis of the bile duct is performed as a duct-to-duct reconstruction, which makes endoscopic therapy with endoscopic retrograde cholangiography (ERC) feasible. Biliary anastomotic strictures (AS) are the most common cause of biliary complications. The early detection of an AS, which can sometimes be challenging given that its clinical presentation is often subtle, is of key importance to obtain high treatment success. In this review, we focus on the management of AS after LT with a special emphasis on ERC.

Abstract
PURPOSE OF REVIEW The purpose of this study is to provide an overview of bacterial biliary tract infections in liver transplant recipients with a focus on pathogenesis and conservative treatment strategies. RECENT FINDINGS The development of interventional endoscopic and radiologic interventions has improved the outcome of conservative treatments for bile tract strictures and bilomas. However, recent data show an important rise of infections with multidrug-resistant (MDR) pathogens in liver transplant recipients. SUMMARY Both recurrent cholangitis and infected bilomas are bacterial biliary tract infections in liver transplant recipients responsible for significant morbidity and graft loss, which require a multidisciplinary approach. Risk factors for biliary tract strictures and bilomas formation have recently been identified. With the improved outcome of a conservative management including prolonged and/or recurrent antibiotic treatments, the risk of selecting resistant pathogens is increased. There is an urgent need to develop new strategies to reduce the risk of secondary infections by MDR isolates in liver transplant recipients.
