Abstract
Although rare, iatrogenic bile duct injury (BDI) after laparoscopic cholecystectomy may be devastating to the patient. The cornerstones for the initial management of BDI are early recognition, followed by modern imaging and evaluation of injury severity. Tertiary hepato-biliary centre care with a multi-disciplinary approach is crucial. The diagnostics of BDI commences with a multi-phase abdominal computed tomography scan, and when the biloma is drained or a surgical drain is put in place, the diagnosis is set with the help of bile drain output. To visualize the leak site and biliary anatomy, the diagnostics is supplemented with contrast enhanced magnetic resonance imaging. The location and severity of the bile duct lesion and concomitant injuries to the hepatic vascular system are evaluated. Most often, a combination of percutaneous and endoscopic methods is used for control of contamination and bile leak. Generally, the next step is endoscopic retrograde cholangiography (ERC) for downstream control of the bile leak. ERC with insertion of a stent is the treatment of choice in most mild bile leaks. The surgical option of re-operation and its timing should be discussed in cases where an endoscopic and percutaneous approach is not sufficient. The patient's failure to recover properly in the first days after laparoscopic cholecystectomy should immediately raise suspicion of BDI and this merits immediate investigation. Early consultation and referral to a dedicated hepato-biliary unit are essential for the best outcome.

Abstract
Biliary complications are often referred to as the Achilles' heel of liver transplantation (LT). The most common of these complications include strictures, and leaks. Prompt diagnosis and management is key for preservation of the transplanted organ. Unfortunately, a number of factors can lead to delays in diagnosis and make adequate treatment a challenge. Innovations in advanced endoscopic techniques have increased non-surgical options for these complications and in many cases is the preferred approach.

Abstract
Liver transplantation is the current standard of care for end-stage liver disease and an accepted therapeutic option for acute liver failure and primary liver tumors. Despite the remarkable advances in the surgical techniques and immunosuppressive therapy, the postoperative morbidity and mortality still remain high and the leading causes are biliary complications, which affect up to one quarter of recipients. The most common biliary complications are anastomotic and non-anastomotic biliary strictures, leaks, bile duct stones, sludge and casts. Despite the absence of a recommended treatment algorithm many options are available, such as surgery, percutaneous techniques and interventional endoscopy. In the last few years, endoscopic techniques have widely replaced the more aggressive percutaneous and surgical approaches. Endoscopic retrograde cholangiography is the preferred technique when duct-to-duct anastomosis has been performed. Recently, new devices and techniques have been developed and this has led to a remarkable increase in the success rate of minimally invasive procedures. Understanding the mechanisms of biliary complications helps in their early recognition which is the prerequisite for successful treatment. Aggressive endoscopic therapy is essential for the reduction of morbidity and mortality in these cases. This article focuses on the common post-transplant biliary complications and the available interventional treatment modalities.

Abstract
BACKGROUND Endoscopic stents are the first-line treatment in the management of benign biliary stricture (BBS) which include multiple plastic stents (MPSs), fully covered self-expandable metal stents (FCSEMS) including the conventional and modified ones (FCSEMS-C and FCSEMS-M) and biodegradable stents. However, different stents have their distinct advantages and disadvantages. We aim to conduct this systematic review to compare the efficacy of different stents in the management of BBS. METHODS Several databases were searched from inception through March 2018. Studies including >10 patients with postoperative stricture treated with endoscopic stents were enrolled. Pooled odds ratio of outcomes were calculated to compare MPS with FCSEMS. Weighted pooled rates were calculated to show the efficacy of FCSEMS-M, FCSEMS-C, and MPS. RESULTS Twenty-two articles were reviewed including 4 randomized controlled studies, 4 cohort studies, and 14 case series studies. Comparing FCSEMS with MPS, the pooled odds ratio was 0.48 [95% confidence interval (CI): 0.22-1.05] (P=0.07) for stricture resolution, 0.3 (95% CI: 0.1-0.92) (P=0.03) for adverse event, 1.9 (95% CI: 0.3-12) (P=0.49) for stent migration, and 1.38 (95% CI: 0.36-5.3) (P=0.34) for stricture recurrence. The pooled rates for stricture recurrence of MPS, FCSEMS-C, and FCSEMS-M were 19%, 19%, and 7%, respectively. The pooled rates for stent migration were 4% of MPS, 25% of FCSEMS-C, and 3% of FCSEMS-M. CONCLUSIONS FCSEMS-M is more favorable in the management of BBS comparing with MPS or FCSEMS-C. The biodegradable stent may be a promising option but currently available data is insufficient to draw a firm conclusion.

Abstract
BACKGROUND The treatment of post-cholecystectomy bile leak is endoscopic retrograde cholangiography (ERC) with plastic stent (PS) insertion combined with external drainage. Self-expanding biodegradable biliary stents (BDBS) have only recently become available. AIM The aim was to compare success rate, adverse events and costs of BDBS with PS in the treatment of post-cholecystectomy cystic duct leak Materials and methods: Patients recruited prospectively for treatment with BDBS during the period 2014-2017 were compared to a control group treated with PS in a non-randomized setting. RESULTS Altogether 32 patients (median age 68, range 33-88, 59% male) were treated for Strasberg A bile leak over a period of 3.5 years, accounting for 1.8% of all ERCs. Eight patients were treated with BDBS and 24 with PS. Treatment with BDBS was safe; rate of readmissions and 30-day adverse events were 13% in both groups. There was no statistical difference in the clinical success rate. All cases with laparoscopic lavation or re-ERC with stent exchange occurred in the PS group. Total drain output was lower in BDBS patients (330ml vs 83ml, p=.002). All PS patients required another endoscopy for stent removal, whereas all BDBS patients were spared repeated endoscopy. CONCLUSION Treatment of cystic duct leak with BDBS is highly successful and as safe as traditional treatment with PS. The most obvious benefit of BDBS is that it avoids stent removal. The lower drain output after ERC with a trend for fewer unplanned interventions may indicate more efficient leak resolution with the large bore BDBS.

Abstract
Orthotopic liver transplantation is the definitive treatment for end-stage liver disease and hepatocellular carcinomas. Biliary complications are the most common complications seen after transplantation, with an incidence of 10-25%. These complications are seen both in deceased donor liver transplant and living donor liver transplant. Endoscopic treatment of biliary complications with endoscopic retrograde cholangiopancreatography (commonly known as ERCP) has become a mainstay in the management post-transplantation. The success rate has reached 80% in an experienced endoscopist's hands. If unsuccessful with ERCP, percutaneous transhepatic cholangiography can be an alternative therapy. Early recognition and treatment has been shown to improve morbidity and mortality in post-liver transplant patients. The focus of this review will be a learned discussion on the types, diagnosis, and treatment of biliary complications post-orthotopic liver transplantation.

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) has evolved from a diagnostic and therapeutic tool to a predominantly therapeutic tool. There is a limited role for diagnostic ERCP with widespread availability of magnetic resonance cholangiopancreatography and endoscopic ultrasound (EUS). Since its introduction, EUS evolved from a diagnostic imaging modality to one with combined diagnostic and therapeutic capabilities. Currently, ERCP remains the standard of care for biliary decompression. In future, it is possible that EUS guided transmural biliary drainage may replace ERCP for certain indications. Given the risk of adverse events related with these more invasive endoscopic procedures, a multidisciplinary team-based approach is recommended.

Abstract
The two most relevant endoscopic treatable benign biliary diseases (BBD) are benign biliary strictures (BBSs) and biliary leaks (BLs), often associated with high morbidity. The most common endoscopic treatment for biliary strictures involves placement of multiple plastic stents (PSs), with or without balloon dilation, followed by planned exchange of the stents. Thus, there continues to be high interest in pursuing alternative endoscopic approaches that may achieve better results with fewer interventions. In this setting, the use of a fully-covered, self-expandable metal stent (FCSEMS) is an attractive alternative to single or multiple PSs for the treatment of BBDs. A single metal stent can remain in place for a longer period of time before removal; however, the maximum time the stent can be remain in place is still not well defined. The aim of this review is to determine the removal time of the TaeWoong® FCSEMS, placed for BBD. According to our data analysis, considering the absence of loss of the covering of the FCSEMS and of any adverse events during and after stent removal, leaving the TaeWoong medical FCSEMS in situ for an 8 months' period seems to be acceptable for benign biliary diseases. Further studies need to evaluate their removability at 1 year.

Abstract
Biliary complications are considered to be the Achilles' heel of liver transplantation. The most common complications are leaks and bile duct strictures. Strictures can arise at the level of the anastomosis (anastomotic strictures; AS) or at other locations in the biliary tree (non-anastomotic strictures; NAS). Endoscopic treatment via endoscopic retrograde cholangiopancreatography (ERCP) is considered to be the preferred therapy for these complications. This review will focus on the diagnostic modalities, new insights in etiology of biliary complications and outcomes after different endoscopic therapies, in both deceased donor transplantation and living-donor liver transplantations. Advances in recent therapies, such as the use of self-expendable metal stents (SEMS) and endoscopic therapy for patients with a bilio-digestive anastomosis will be discussed.

Abstract
There is growing interest in using covered self-expandable metal stents for the treatment of benign biliary conditions, and the presence of anastomotic biliary strictures and leaks after liver transplantation provide a valuable opportunity for testing them. The performance of the stents is encouraging, and the technical success rate is high. They provide larger diameter dilation and are easily removed, and can potentially limit costs by reducing the number of procedures needed to treat anastomotic biliary strictures. However, drawbacks such as sub-optimal tolerability and migration may affect both patient management and costs. New stent designs are currently being evaluated. Randomized controlled trials and cost-effectiveness analyses comparing covered metal stents with multiple plastic stent endotherapy are warranted in order to define the role of the former as first-line or rescue treatment.

Abstract
Endoscopic stenting has become a widely method for the management of various malignant and benign pancreatico-biliary disorders. Biliary and pancreatic stents are devices made of plastic or metal used primarily to establish patency of an obstructed bile or pancreatic duct and may also be used to treat biliary or pancreatic leaks, pancreatic fluid collections and to prevent post-endoscopic retrograde cholangiopancreatography pancreatitis. In this review, relevant literature search and expert opinions have been used to evaluate the outcome of stenting in biliary and pancreatic benign and malignant diseases.

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
Laparoscopic cholecystectomy has become the procedure of choice for management of symptomatic cholelithiasis. Although it has distinct advantages over open cholecystectomy, bile leak is more common. Endoscopic retrograde cholangiopancreatography is the diagnostic and therapeutic modality of choice for management of postcholecystectomy bile leaks and has a high success rate with the placement of plastic biliary stents. Repeat endoscopic retrograde cholangiopancreatography with placement of multiple plastic stents, a covered metal stent, or possibly cyanoacrylate therapy may be effective in refractory cases. This review will discuss the indications, efficacy, and complications of endoscopic therapy.

Abstract
PURPOSE OF REVIEW Biliary complications account for relevant morbidity and mortality after liver transplantation. Advances have taken place in understanding their aetiology, in preventive operative techniques, imaging procedures, as well as interventional and endoscopic management. However, progress in living donation, donation after cardiac death as well as paediatric transplant procedures have changed the incidence and causes of biliary complications. This review summarizes recent progress in the field, particularly related to biliary strictures after liver transplantation. RECENT FINDINGS Significant findings in the period of interest for this review focussed on improvements of endoscopic treatment of postliver transplant biliary complications, including novel stenting devices, the routine analysis of bacterial and fungal flora, and the use of steroids to prevent postendoscopic retrograde cholangiopancreaticography pancreatitis. The importance of cytomegalovirus and hepatitis C in the aetiology of biliary complications was highlighted. Under certain circumstances, biliary complications after liver transplantation of organs secondary to donation after cardiac death may be reduced to a level known from liver transplantation after brain death. Further evidence was added to support the risk-adapted use of biliary drainage during liver transplantation. SUMMARY The ongoing research in the aetiology, prevention, and treatment of biliary strictures after liver transplantation highlights the significance of biliary complications for patient and graft outcome.

Abstract
The majority of recent studies of benign biliary strictures (BBSs) have reported on treatment of stenotic injuries following cholecystectomy, orthotopic liver transplantation, living donor liver transplantation, chronic pancreatitis, and different inflammatory conditions such as common bile-duct-related strictures. Information about previous surgical procedures is very important for making a BBS diagnosis. Diagnostic tools for indeterminate strictures have increased to include (1) highly specialized cytological techniques such as fluorescence in situ hybridization, (2) cholangioscopy, and (3) endoscopic ultrasound with fine needle aspiration (FNA) and intraductal ultrasound. Magnetic resonance cholangiopancreatography before endoscopic retrograde cholangiopancreatography (ERCP) usually provides an adequate map to plan the endoscopic therapy. After traversing the stricture with a guidewire and, occasionally, performing balloon dilatation, plastic stents continue to be the basic endotherapy, trying to insert the maximum possible number, with an exchange every 3 months during a 12-month period. Progressive stenting requires a median number of five ERCPs; therefore, it is technically demanding and burdensome but has an average of 80% long-term durable stricture dilation. For not-hilar BBS, fully covered self-expanding metal stents (FCSEMSs) are emerging as a promising therapy needing fewer of the endoscopist's technical skills and reducing ERCP procedures and, probably, costs. To equal a 10-mm diameter provided by a single FCSEMS, about three plastic stents placed side-by-side are needed. Manufacturers are working to improve FCSEMS designs to reduce migration rate and to allow an easy extraction after several months in place. Many studies have tried to show reproducible protocols for the duration of FCSEMS therapy and the results in different types of BBSs.
