Abstract
Endoscopic therapy is the first line of management for chronic pancreatitis (CP)-related benign biliary strictures. Multiple plastic stents (MPS) exchanged at regular intervals and temporary placement of fully covered self-expanding metal stents (FCSEMS) are preferred modalities of endotherapy. FCSEMS placement is non-inferior to MPS and requires fewer sessions of endoscopic retrograde cholangiopancreatography than MPS placement. The presence of head calcifications, severe CP, and length of stricture are predictors of failure or recurrence after endotherapy. Failure of endotherapy should be considered after 1 year when surgery should be considered.

Biomechanical Behaviors and Degradation Properties of Multilayered Polymer Scaffolds: The Phase Space Method for Bile Duct Design and Bioengineering. Biomedicines 2023; 11:biomedicines11030745.

Abstract
This article reports the electrospinning technique for the manufacturing of multilayered scaffolds for bile duct tissue engineering based on an inner layer of polycaprolactone (PCL) and an outer layer either of a copolymer of D,L-lactide and glycolide (PLGA) or a copolymer of L-lactide and ε-caprolactone (PLCL). A study of the degradation properties of separate polymers showed that flat PCL samples exhibited the highest resistance to hydrolysis in comparison with PLGA and PLCL. Irrespective of the liquid-phase nature, no significant mass loss of PCL samples was found in 140 days of incubation. The PLCL- and PLGA-based flat samples were more prone to hydrolysis within the same period of time, which was confirmed by the increased loss of mass and a significant reduction of weight-average molecular mass. The study of the mechanical properties of developed multi-layered tubular scaffolds revealed that their strength in the longitudinal and transverse directions was comparable with the values measured for a decellularized bile duct. The strength of three-layered scaffolds declined significantly because of the active degradation of the outer layer made of PLGA. The strength of scaffolds with the PLCL outer layer deteriorated much less with time, both in the axial (p-value = 0.0016) and radial (p-value = 0.0022) directions. A novel method for assessment of the physiological relevance of synthetic scaffolds was developed and named the phase space approach for assessment of physiological relevance. Two-dimensional phase space (elongation modulus and tensile strength) was used for the assessment and visualization of the physiological relevance of scaffolds for bile duct bioengineering. In conclusion, the design of scaffolds for the creation of physiologically relevant tissue-engineered bile ducts should be based not only on biodegradation properties but also on the biomechanical time-related behavior of various compositions of polymers and copolymers.

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
BACKGROUND Endoscopic fully-covered self-expandable metal stents (FCSEMSs) are used to treat benign biliary strictures (BBSs); however, treatment for perihilar BBSs is technically challenging. The aim of this study was to evaluate the usefulness of an unflared FCSEMS designed for intraductal placement in patients with refractory perihilar BBS. METHODS Twenty-two consecutive patients with perihilar BBS unresolved by endoscopic plastic stent placement at 13 tertiary medical centers were prospectively enrolled. The FCSEMS was placed above the papilla and removed after 4 months. The primary outcome was stricture resolution at 4 months, and the secondary outcomes were technical success, stent removal, adverse events, and recurrence. RESULTS The technical success rate of intraductal FCSEMS placement was 100%, and plastic stent placement at contralateral or side branch was performed in 86% of patients. The rate of successful stent removal at 4 months was 100%, and stricture resolution was observed in 91% of patients. Stent migration or stent-induced de novo stricture did not occur in any patient. The stricture recurrence rate was 16%, and the median (interquartile range) follow-up duration was 2.8 (1.6-3.3) years. CONCLUSIONS Intraductal placement of unflared FCSEMS is effective treatment for refractory perihilar BBS.

Abstract
Benign biliary strictures (BBS) are usually treated with endoscopic retrograde cholangiopancreatography (ERCP) with the placement of multiple plastic stents (MPS) or a covered self-expandable metal stent (CSEMS). In this meta-analysis, we compared the efficacy and safety of MPS and CSEMS in the management of BBS. We reviewed several databases from inception to 28 April 2021 to identify RCTs that compared MPS with CSEMS in the management of BBS. Our outcomes of interest were stricture resolution, stricture recurrence, adverse events, stent migration and mean number of ERCPs to achieve stricture resolution. Data were analyzed using a random-effects model. We included eight RCTs with 524 patients. We found no significant difference in the rate of stricture resolution (risk ratio, 1.02; 95% CI, 0.96-1.10), stricture recurrence (risk ratio, 1.68; 95% CI, 0.72-3.88) or adverse events (risk ratio, 1.17; 95% CI, 0.73-1.87) between groups. Mean number of ERCPs was significantly lower in the CSEMS group (SMD, -1.99; 95% CI, -3.35 to -0.64). The rate of stent migration was significantly higher in the CSEMS group. CSEMS are comparable in efficacy and safety to MPS in the management of BBS but require fewer ERCPs to achieve stricture resolution.

Abstract
BACKGROUND The management of difficult lithiasis of common bile duct (CBD) often requires a multimodal approach. Fully Covered Metal Stents (FCSEMS) could fragment the stones, dilate strictures of the CBD and progressively enlarge the papillary orifice. The aim of the study was to evaluate the efficacy of FCSEMS in the treatment of difficult lithiasis of CBD. METHODS All consecutive cases of difficult lithiasis of CBD after an attempt of clearance with complete sphincterotomy were retrospectively considered from 2009 to 2019. Intrahepatic lithiasis cases were excluded. Multivariable analysis (stepwise logistic regression if p value < 0.1 at univariable analysis) was made to understand factors associated with efficacy of FCSEMS in difficult lithiasis of CBD. RESULTS 163 cases of difficult lithiasis over 1516 cases of lithiasis of CBD (incidence of 11%) were considered. Among eligible patients, 96 (mean age 78 ± 11.9 years, 43% males) placed a FCSEMS during the first ERCP. Mean diameter of stone was 17.5 ± 5.5 mm. An attempt of dilation during the same procedure was made in 18% cases. After removal of the stent, 52 (54%) patients had complete clearance of CBD at cholangiography. The rest of patients (44), subsequently underwent multimodal treatment (final success of 95%). After logistic regression, variables positively associated with clearance of CBD were sex male (OR 3.5) and stent permanence ≥ 30 days (OR 3.2). Diameter of the stone ≥ 2 cm was associated with failure (OR 0.2). 7 post-ERCP pancreatitis, 6 post-sphincterotomy bleeding and 3 cholangitis occurred. CONCLUSIONS FCSEMS are useful in the approach of difficult lithiasis of CBD with no significant adverse events associated.

Abstract
Background/Aims This study assessed the significance of biliary stricture in symptomatic chronic pancreatitis patients requiring extracorporeal shock wave lithotripsy (ESWL) and endoscopic retrograde cholangiopancreatography (ERCP) to remove obstructing pancreatic calculi. Methods A total of 97 patients underwent ESWL followed by ERCP to remove pancreatic calculi between October 2014 and October 2017 at Virginia Mason Medical Center. Significant biliary stricture (SBS) was defined as a stricture with upstream dilation on computed tomography scan or magnetic resonance cholangiopancreatography scans accompanied by cholestasis and/or cholangitis. SBS was initially managed by either a plastic stent or fully covered self-expandable metallic stent (fcSEMS). If the stricture did not resolve, the stent was replaced with either multiple plastic stents or another fcSEMS. Data were collected by retrospectively reviewing the medical records. Results Biliary strictures were noted in approximately one-third of patients (34/97, 35%) undergoing ESWL for pancreatic calculi. Approximately one-third of the biliary strictures (11/34, 32%) were SBS. Pseudocysts were more frequently found in those with SBS (36% vs 8%, p=0.02), and all pseudocysts in the SBS group were located in the pancreatic head. The initial stricture resolution rates with fcSEMSs and plastic prostheses were 75% and 29%, respectively. The overall success rate for stricture resolution was 73% (8/11), and the recurrence rate after initial stricture resolution was 25% (2/8). Conclusions Although periductal fibrosis is the main mechanism underlying biliary stricture development in chronic pancreatitis, inflammation induced by obstructing pancreatic calculi, including pseudocysts, is an important contributing factor to SBS formation during the acute phase.

Abstract
BACKGROUND/OBJECTIVES This paper is part of the international consensus guidelines on chronic pancreatitis, presenting for interventional endoscopy. METHODS An international working group with experts on interventional endoscopy evaluated 26 statements generated from evidence on 9 clinically relevant questions. The Grading of Recommendations Assessment, Development, and Evaluation approach was used to evaluate the level of evidence. To determine the level of agreement, a nine-point Likert scale was used for voting on the statements. RESULTS Strong consensus was obtained for 15 statements relating to nine questions including the recommendation that endoscopic intervention should be offered to patients with persistent severe pain but not to those without pain. Endoscopic decompression of the pancreatic duct could be used for immediate pain relief, and then offered surgery if this fails or needs repeated endoscopy. Endoscopic drainage is preferred for portal-splenic vein thrombosis and pancreatic fistula. A plastic stent should be placed and replaced 2-3 months later after insertion. Endoscopic extraction is indicated for stone fragments remaining after ESWL. Interventional treatment should be performed for symptomatic/complicated pancreatic pseudocysts. Endoscopic treatment is recommended for bile duct obstruction and afterwards surgery if this fails or needs repeated endoscopy. Surgery may be offered if there is significant calcification and/or mass of the pancreatic head. Percutaneous endovascular treatment is preferred for hemosuccus pancreaticus. Surgical treatment is recommended for duodenal stenosis due to chronic pancreatitis. CONCLUSIONS This international expert consensus guideline provides evidenced-based statements concerning indications and key aspects for interventional endoscopy in the management of patients with chronic pancreatitis.

Abstract
Benign biliary strictures can be difficult to manage. Untreated biliary strictures can lead to complications, such as chronic cholestasis, jaundice, recurrent sepsis, and secondary biliary cirrhosis, which can have severe ramifications. The management landscape is constantly evolving, with the development of modifiable self-expandable metal stents and biodegradable stents. This review critically appraises current endoscopic treatment strategies, in particular focusing on the shortfalls, such as stent migration and stricture recurrence. It also proposes a treatment algorithm based on aetiologias and the location of the strictures.

Abstract
BACKGROUND AND AIMS Endoscopic therapy of benign biliary strictures with multiple plastic stent (MPS) placement has shown satisfactory results. However, the literature describes various benign biliary stricture etiologies. The aim of this study was to evaluate long-term MPS results in patients with postcholecystectomy biliary strictures (PCBSs). METHODS PCBS patients without complete bile duct transection were included. ERCP consisted of placing an increasing plastic stent number over time, exchanged at regular intervals (3-4 months), until complete morphologic stricture disappearance. After stent removal, patient follow-up comprised liver function tests and clinical assessment. RESULTS One hundred fifty-four patients (43.5% men; mean age, 53 years) were enrolled; in 43% of the cases, PCBSs were involved or were close to the main hepatic confluence. PCBS resolution rate was 96.7% (n = 149). A mean maximum number of 4.3 ± 1.6 stents were placed side-by-side; a mean of 4.2 ± 1.5 ERCPs per patient was needed to obtain PCBS resolution during a mean treatment period of 11.8 ± 6.4 months. Unscheduled stent exchange because of cholangitis, jaundice, or pain occurred in 7.4% of cases. Procedure-related mortality was absent. Follow-up data were available in 85.2% of cases. After a mean follow-up of 11.1 ± 4.9 years, stricture recurrence rate was 9.4% (n = 12). Subsequent to retreatment, 83.3% of patients (n = 10) were asymptomatic after a mean time of 9 years, whereas 2 patients underwent hepaticojejunostomy because of failed retreatment. Statistical analysis revealed no risk factors for PCBS recurrence after MPS. CONCLUSIONS Endoscopic therapy of PCBSs with MPSs is safe and effective at long-term follow-up. PCBSs involving or close to the main hepatic confluence were successfully treated with MPSs. PCBS recurrence rate is low and can be successful endoscopically retreated without precluding possible surgical treatment.

Abstract
Background Endoscopic treatment of post-cholecystectomy biliary strictures (PCBS) with multiple plastic biliary stents placed sequentially is a minimally invasive alternative to surgery but requires multiple interventions. Temporary placement of a single fully-covered self-expanding metal stent (FCSEMS) may offer safe and effective treatment with fewer re-interventions. Long-term effectiveness of treatment with FCSEMS to obtain PCBS resolution has not yet been studied. Methods In this prospective multi-national study in patients with symptomatic benign biliary strictures (N = 187) due to various etiologies received a FCSEMS with scheduled removal at 6–12 months and were followed for 5 years. We report here long-term outcomes of the subgroup of patients with PCBS (N = 18). Kaplan Meier analyses assessed long-term freedom from re-stenting. Adverse events were documented. Results Endoscopic removal of the FCSEMS was achieved in 83.3% (15/18) of patients after median indwell of 10.9 (range 0.9–13.8) months. In the remaining 3 patients (16.7%), the FCSEMS spontaneously migrated and passed without complications. At the end of FCSEMS indwell, 72% (13/18) of patients had stricture resolution. At 5 years after FCSEMS removal, 84.6% (95% CI 65.0–100.0%) of patients who had stricture resolution at FCSEMS removal remained stent-free. In addition, at 75 months after FCSEMS placement, the probability of remaining stent-free was 61.1% (95% CI 38.6–83.6%) for all patients. Stent or removal related serious adverse events occurred in 38.9% (7/18) all resolved without sequalae. Conclusions In patients with symptomatic PCBS, temporary placement of a single FCSEMS intended for 10–12 months indwell is associated with long-term stricture resolution up to 5 years. Temporary placement of a single FCSEMS may be considered for patients with PCBS not involving the main hepatic confluence.

Abstract
PURPOSE OF REVIEW Benign biliary strictures can be treated with plastic stents and self-expandable metal stents (SEMS). This review article delineates the latest scientific evidence for their usage. RECENT FINDINGS Despite evolving literature on both type of stents as treatment modalities of benign biliary strictures, which encompass mainly anastomotic strictures and strictures related to chronic pancreatitis, no final conclusions can be drawn regarding the superiority of a particular stent. SEMS tend to have higher stricture resolution rates and fewer procedural requirements which are partly offset by higher stent migration and stricture recurrence rates compared with plastic stents. Additional studies focusing on new SEMS types with anti-migration features as well as cost-effectiveness calculations are necessary for clinical decision-making when treating patients with benign biliary strictures.

Abstract
Benign biliary strictures (BBSs) may form from chronic inflammatory pancreaticobiliary pathologies, postoperative bile-duct injury, or at biliary anastomoses following liver transplantation. Treatment aims to relieve symptoms of biliary obstruction, maintain long-term drainage, and preserve liver function. Endoscopic therapy, including stricture dilatation and stenting, is effective in most cases and the first-line treatment of BBS. Radiological and surgical therapies are reserved for patients whose strictures are refractory to endoscopic interventions. Response to treatment is dependent upon the technique and accessories used, as well as stricture etiology. In this review, we discuss the various BBS etiologies and their management strategies.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic inflammatory disease of the biliary tree of unknown etiology leading to stricturing and dilation. There is currently no effective medical therapy for PSC and liver transplantation (LT) remains the ultimate treatment for severe disease defined as repeated episodes of cholangitis, decompensated biliary cirrhosis or in exceptional cases, cholangiocarcinoma (CCA). Patients often present with a "dominant" stricture and the therapeutic endoscopist plays an important role in management to improve biliary patency using a variety of techniques that involve sampling, balloon dilation and temporary stenting. Newer modalities such as self-expanding metal stents or magnetic compression anastomosis that have been used in other diseases may have a role to play in PSC but should remain investigational. Liver transplantation for PSC is curative in most cases but the optimal timing remains unclear. The lifetime risk of CCA is 10-15% in PSC patients and LT is often not possible at the time of diagnosis. Multiple studies have tried to identify risk factors and to diagnose CCA at an early stage when surgical resection may be possible or LT can be performed. However, deceased donor organs for LT remain in short supply throughout the world so even identifying PSC patients with CCA at an early stage may not be beneficial unless a live donor organ is available.

Clinical efficacy of anti-migration features in fully covered metallic stents for anastomotic biliary strictures after liver transplantation: comparison of conventional and anti-migration stents. Gastrointest Endosc 2018; 88:655-664. [PMID: 30003877 DOI: 10.1016/j.gie.2018.06.035] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2018] [Accepted: 06/26/2018] [Indexed: 02/06/2023]
Abstract
BACKGROUND AND AIMS Anastomotic biliary strictures (ABSs) are one of the most frequent adverse events that occur after orthotopic liver transplantation (OLT). Multiple plastic stents (MPS) have been validated for this indication. More recently, fully covered self-expandable metallic stents (FCSEMSs) have been used with positive outcomes, but also have a higher rate of migration, which may limit success. Our primary objective was to compare stent migration rates observed with standard FCSEMSs (Std-FCSEMSs) and so-called anti-migration FCSEMSs (Am-FCSEMSs), which are newly designed with reversed proximal side flaps. Secondary objectives were to compare rates of stricture resolution and procedure-related morbidity. METHODS We conducted a retrospective analysis of a subset of patients (FCSEMSs for post-OLT ABS) from 2 prospectively maintained databases of (1) OLT patients, and (2) ERCP and stent placement. Between January 2009 and January 2016, consecutive patients presenting with ABS after OLT referred to Cochin Hospital (Paris, France) for ERCP and receiving a FCSEMS were included. Exclusion criteria were any other cause of biliary stricture (ie, malignant stricture, ischemic origin), and biliary fistulae. RESULTS One hundred twenty-five FCSEMSs (57 Am-FCSEMSs, 52 type 1 Std-FCSEMSs, and 16 type 2 Std-FCSEMSs) were used in 75 patients for ABS after OLT, with a planned stent placement period of 6 months in all patients. Patient characteristics and rates of previous endoscopic treatment or timing of ABS occurrence after OLT were not different between the groups. The rate of FCSEMS complete migration was 16% (20/125), consisting of 1.7% (1/57) for Am-FCSEMSs and 28% (19/68) for type 1 and 2 Std-FCSEMSs (P < .0001). All attempted stent removals (100% of patients) were successful. First follow-up ERCP after each FCSEMS highlighted a stricture resolution rate of 78.4% (98/125), including 93% (53/57) for Am-FCSEMSs and 66.2% (45/68) for type 1 and 2 Std-FCSEMSs (P < .001). After a median follow-up of 28 months after stent removal (range, 12-66 months), stricture recurrence was observed in 12.3% (range, 11%-17%) of patients treated with Am-FCSEMSs against 55.9% (range, 54%-56%) of those receiving Std-FCSEMSs (P < .0001). CONCLUSIONS In patients with ABS after OLT, the use of Am-FCSEMSs significantly decreased the risk of stent migration, improved stricture resolution at the time of stent removal, and reduced the rate of stricture recurrence during follow-up. Endoscopic removal success and procedure-related morbidity were similar for both standard and anti-migration stents.

Abstract
BACKGROUND Endoscopic placement of multiple plastic stents (MPS) has been the first-line treatment for benign biliary stricture (BBS). Covered self-expanding metal stents (cSEMS) have been used in treatment of BBS; however, the efficacy has not been verified. Therefore, we conducted this meta-analysis according to PRISMA guidelines. METHODS PubMed, Embase, and the Cochrane Library were electronically and manually searched for studies published between January 1, 1990 and April 12, 2017. Of 153 studies screened, 90 were excluded because of duplications. After scanning the title or abstract, only 24 studies were eligible for review and 6 were finally included. The investigators selected publications according to inclusion and exclusion criteria, processed the data, and assessed the quality of the selected studies. The primary endpoint outcome was stricture resolution, and the secondary endpoint outcomes included stricture recurrence rate, the number of endoscopic retrograde cholangiopancreatography (ERCP) sessions, and stent migration. RESULTS A total of 6 randomized controlled trials with 330 participants were included in the current meta-analysis. There was no significant difference in stricture resolution between the cSEMS and MPS groups (odds ratio [OR] = 1.05, 95% confidence interval [CI] = 0.53-2.07, I = 29%, P = .23, Z = 0.13, P = .90). Similarly, the stricture recurrence rates (OR = 1.39, 95% CI = 0.69-2.81, I = 38%, P = .17, Z = 0.91, P = .36) were comparable between cSEMS and MPS groups. Stent migration rates (OR = 1.71, 95% CI = 0.84-3.50, I = 4%, P = .241, Z = 1.47, P = .14) were similar between cSEMS and MPS groups. There were fewer ERCP sessions in the cSEMS group than in the MPS group. CONCLUSIONS This meta-analysis showed that cSEMS were comparable to MPS in achieving resolution of BBSs with fewer ERCP procedures.

Abstract
Chronic pancreatitis is defined as a pathological fibro-inflammatory syndrome of the pancreas in individuals with genetic, environmental and/or other risk factors who develop persistent pathological responses to parenchymal injury or stress. Potential causes can include toxic factors (such as alcohol or smoking), metabolic abnormalities, idiopathic mechanisms, genetics, autoimmune responses and obstructive mechanisms. The pathophysiology of chronic pancreatitis is fairly complex and includes acinar cell injury, acinar stress responses, duct dysfunction, persistent or altered inflammation, and/or neuro-immune crosstalk, but these mechanisms are not completely understood. Chronic pancreatitis is characterized by ongoing inflammation of the pancreas that results in progressive loss of the endocrine and exocrine compartment owing to atrophy and/or replacement with fibrotic tissue. Functional consequences include recurrent or constant abdominal pain, diabetes mellitus (endocrine insufficiency) and maldigestion (exocrine insufficiency). Diagnosing early-stage chronic pancreatitis is challenging as changes are subtle, ill-defined and overlap those of other disorders. Later stages are characterized by variable fibrosis and calcification of the pancreatic parenchyma; dilatation, distortion and stricturing of the pancreatic ducts; pseudocysts; intrapancreatic bile duct stricturing; narrowing of the duodenum; and superior mesenteric, portal and/or splenic vein thrombosis. Treatment options comprise medical, radiological, endoscopic and surgical interventions, but evidence-based approaches are limited. This Primer highlights the major progress that has been made in understanding the pathophysiology, presentation, prevalence and management of chronic pancreatitis and its complications.

Abstract
BACKGROUND AND AIM Management of benign biliary stricture is challenging. Endoscopic therapy has evolved as the first-line treatment for various benign biliary strictures. However, covered self-expandable metal stents (CSEMS) have not been approved by the United States Food and Drug Administration for the treatment of benign biliary stricture. With this goal, we conducted the present systemic review and meta-analysis to evaluate the efficacy and safety of endoscopic stenting with CSEMS in the treatment of benign biliary stricture. METHODS Systematic review and meta-analysis by searching PubMed, MEDLINE and Embase databases. RESULTS In total, 37 studies (1677 patients) fulfilled the inclusion criteria. Pooled stricture resolutions were achieved in 83% of cases. Median stent dwelling time was 4.4 months, with median endoscopic retrograde cholangiopancreatography sessions of 2.0. Stricture recurrence at 4-year follow up was 11% (95% CI, 8-14%). Pooled complication rate was 23% (95% CI, 20-26%). CONCLUSIONS Placement of CSEMS is effective in the treatment of benign biliary stricture with relatively short stenting duration and low long-term stricture recurrence rate. However, more prospectively randomized studies are required to confirm the results.

Abstract
Background Benign biliary stricture is a rare condition and the majority of the cases are caused by operative trauma or chronic inflammation based on various etiology. Although the initial results of endoscopic, percutaneous and surgical treatment are impressive, no comparison about long term stricture resolution is available. Aims The goal of this study was to compare the long term disease free survival in benign biliary strictures with various etiology after surgery, percutaneous transhepatic—and endoscopic treatment. Methods PubMed, Embase, and Cochrane Library were searched by computer and manually for published studies. The investigators selected the publications according to the inclusion and exclusion criteria, processed the data and assessed the quality of the selected studies. Meta-analysis of data of 24 publications was performed to compare long term disease free survival of different treatment groups. Results Compared the subgroups surgery resulted in the highest long term stricture resolution rate, followed by the percutaneous transhepatic treatment, the multiple plastic stent insertion and covered self-expanding metal stents (SEMS), however the difference was not significant. All compared methods are significantly superior to the single plastic stent placement. Long term stricture resolution rate irrespectively of any therapy is still not more than 84%. Conclusions In summary, the use of single plastic stent is not recommended. Further randomized studies and innovative technical development are required for improving the treatment of benign biliary strictures.

Abstract
BACKGROUND Surgically altered gastrointestinal anatomy poses challenges for deep enteroscopy. Current overtube-assisted methods have long procedure times and utilize endoscopes with smaller working channels that preclude use of standard accessories. A through-the-scope balloon-assisted enteroscopy (TTS-BAE) device uses standard endoscopes with a large working channel to allow metallic and plastic stent insertion. We aim to determine the efficacy and safety of TTS-BAE in patients with altered surgical anatomy. METHODS A retrospective, multicenter study of TTS-BAE in altered anatomy patients at two USA and one German institution was performed between January 2013 and December 2014. Type of anatomy, procedure indication and duration, adverse events, and target, technical, and clinical success were recorded. RESULTS A total of 32 patients (mean age 54 years, Caucasian 81.6%, female 42.1%, mean BMI 25.4 kg/m2) underwent 38 TTS-BAE procedures. Thirty-two percent of cases had a prior attempt at conventional enteroscopy which failed to reach the target site. The target was successfully reached in 23 (60.5%) cases. Of the 23 cases that reached the intended target, 22 (95.7%) achieved technical success and 21 (91.3%) achieved clinical success. The median procedure time was 43 min. Target, technical, and clinical success rates for TTS-BAE-assisted ERCP (n = 31) were 58.1, 54.8 and 54.8%. Seven self-expandable metallic stents (five biliary, two jejunal) were attempted, and all successfully deployed. Adverse events occurred in 4 (10.4%) cases, including one luminal perforation. CONCLUSION TTS-BAE is an alternative to overtube-assisted enteroscopy that is comparable in safety in patients with surgically altered anatomies. Technical success in the instances where the target had been reached was excellent. TTS-BAE confers an advantage over overtube-assisted enteroscopy as it can facilitate the deployment of self-expandable metallic stents in the biliary tree and deep small bowel.

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 Temporary placement of removable, fully covered, self-expandable metal stents (fcSEMS) for treatment of benign biliary strictures (BBS) has been reported to be effective. However, the optimal extraction time point remains unclear and stent migration has been a major concern. OBJECTIVE The objective of this study was to evaluate the efficacy and safety of this treatment modality using an fcSEMS with a special antimigration design and prolonged stent indwell time. METHODS We performed a prospective, single-arm study at six tertiary care centers in Europe. Patients with BBS underwent endoscopic or percutaneous implantation of an fcSEMS (GORE® VIABIL® Biliary Endoprosthesis, W.L. Gore & Associates, Flagstaff, AZ, USA). The devices were scheduled to be removed nine months later, and patients were to return for follow-up for an additional 15 months. RESULTS Forty-three patients were enrolled in the study. Stricture etiology was chronic pancreatitis in the majority of patients (57.5%). All fcSEMS were placed successfully, either endoscopically (76.7%) or percutaneously (23.3%). Stent migration was observed in two patients (5.2%). Primary patency of the SEMS prior to removal was 73.0%. All attempted stent removals were successful. At removal, stricture was resolved or significantly improved without need for further therapy in 78.9% of patients. Stricture recurrence during a follow-up of two years post-implant was observed in two patients. CONCLUSIONS Temporary placement of the fcSEMS is a feasible, safe and effective treatment for BBS. The design of the device used in this study accounts for very low migration rates and facilitates easy stent retrieval, even after it has been in place for up to 11 months.

Abstract
IMPORTANCE Endoscopic placement of multiple plastic stents in parallel is the first-line treatment for most benign biliary strictures; it is possible that fully covered, self-expandable metallic stents (cSEMS) may require fewer endoscopic retrograde cholangiopancreatography procedures (ERCPs) to achieve resolution. OBJECTIVE To assess whether use of cSEMS is noninferior to plastic stents with respect to stricture resolution. DESIGN, SETTING, AND PARTICIPANTS Multicenter (8 endoscopic referral centers), open-label, parallel, randomized clinical trial involving patients with treatment-naive, benign biliary strictures (N = 112) due to orthotopic liver transplant (n = 73), chronic pancreatitis (n = 35), or postoperative injury (n = 4), who were enrolled between April 2011 and September 2014 (with follow-up ending October 2015). Patients with a bile duct diameter less than 6 mm and those with an intact gallbladder in whom the cystic duct would be overlapped by a cSEMS were excluded. INTERVENTIONS Patients (N = 112) were randomized to receive multiple plastic stents or a single cSEMS, stratified by stricture etiology and with endoscopic reassessment for resolution every 3 months (plastic stents) or every 6 months (cSEMS). Patients were followed up for 12 months after stricture resolution to assess for recurrence. MAIN OUTCOMES AND MEASURES Primary outcome was stricture resolution after no more than 12 months of endoscopic therapy. The sample size was estimated based on the noninferiority of cSEMS to plastic stents, with a noninferiority margin of -15%. RESULTS There were 55 patients in the plastic stent group (mean [SD] age, 57 [11] years; 17 women [31%]) and 57 patients in the cSEMS group (mean [SD] age, 55 [10] years; 19 women [33%]). Compared with plastic stents (41/48, 85.4%), the cSEMS resolution rate was 50 of 54 patients (92.6%), with a rate difference of 7.2% (1-sided 95% CI, -3.0% to ∞; P < .001). Given the prespecified noninferiority margin of -15%, the null hypothesis that cSEMS is less effective than plastic stents was rejected. The mean number of ERCPs to achieve resolution was lower for cSEMS (2.14) vs plastic (3.24; mean difference, 1.10; 95% CI, 0.74 to 1.46; P < .001). CONCLUSIONS AND RELEVANCE Among patients with benign biliary strictures and a bile duct diameter 6 mm or more in whom the covered metallic stent would not overlap the cystic duct, cSEMS were not inferior to multiple plastic stents after 12 months in achieving stricture resolution. Metallic stents should be considered an appropriate option in patients such as these. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT01221311.

Abstract
Historically, neoplasia of the duodenal papilla has been managed surgically, which may be associated with substantial morbidity and mortality. In the absence of invasive cancer, even lesions with extensive lateral duodenal wall involvement, or limited intraductal extension may be cured endoscopically with a superior safety profile. Endoscopic papillectomy is associated with greater risks of adverse events such as bleeding than resection elsewhere in the gastrointestinal tract. Additionally site-specific complications such as pancreatitis exist. A structured approach to lesion assessment, adherence to technical aspects of resection, endoscopic management of complications and post-resection surveillance is required. Advances have been made in all facets of endoscopic papillary resection since its introduction in the 1980s; extending the boundaries of endoscopic cure, optimizing outcomes and enhancing patient safety. These will be the focus of the present review.

Abstract
Interventional radiologists are often consulted to help identify and treat biliary strictures that can result from a variety of benign etiologies. Mainstays of noninvasive imaging for benign biliary strictures include ultrasound, contrast-enhanced computed tomography and magnetic resonance imaging, magnetic resonance cholangiopancreatography, and computed tomography cholangiography. Endoscopic retrograde cholangiography is the invasive diagnostic procedure of choice, allowing both localization of a stricture and treatment. Percutaneous biliary interventions are reserved for patients who are not candidates for endoscopic retrograde cholangiography (eg, history of distal gastrectomy and biliary-enteric anastomosis to a jejunal roux limb). This review discusses the roles of percutaneous transhepatic cholangiography and biliary drainage in the diagnosis of benign biliary strictures. The methodology for crossing benign biliary strictures, approaches to balloon dilation, management of recalcitrant strictures (ie, large-bore biliary catheters and retrievable covered stents), and the expected outcomes and complications of percutaneous treatment of benign biliary strictures are also addressed.
