Abstract
INTRODUCTION The current endoscopic treatment for postoperative benign hepaticojejunostomy anastomotic stricture (HJAS) has a high technical success rate and is highly effective in the short term. However, long-term results have shown a high rate of stenosis recurrence, which indicates an insufficient response to treatment. Three prospective studies on fully covered self-expandable metallic stent (FC-SEMS) treatment for benign HJAS used the stenosis resolution rate as the primary endpoint, and no study has yet used the long-term non-stenosis rate (at 12 months) as the primary endpoint. METHODS AND ANALYSIS We launched the 'saddle-cross study', which will be conducted as a multicentre, prospective intervention of endoscopic treatment using two modified FC-SEMSs (BONASTENT️ M-Intraductal) that have been improved for benign stenosis in patients with benign HJAS, with the long-term non-restenosis rate (at 12 months) as the primary endpoint. This study aims to evaluate the long-term non-restenosis rate (at 12 months) and safety of the saddle-cross technique for benign HJAS. We plan to enrol 50 participants. ETHICS AND DISSEMINATION This study has been approved by the Certified Review Board of the National Cancer Center, Japan (CRB3180009). The results will be reported at various conferences and published in international peer-reviewed journals.

Abstract
BACKGROUND In recent years, the number of patients with hepaticojejunostomy anastomotic strictures has increased. Balloon dilation and placement of multiple plastic stents have proven effective for hepaticojejunostomy anastomotic strictures. However, for refractory strictures, there is often a need for repeated endoscopic procedures within a short period. This study aimed to assess the efficacy and safety of the new saddle-cross technique, which uses two fully covered self-expandable metallic stents. METHODS This was a retrospective analysis of 20 patients with benign hepaticojejunostomy anastomotic strictures who underwent placement of two fully covered self-expandable metallic stents at the National Cancer Center, Japan, from November 2017 to June 2021. RESULTS The technical and clinical success rates were 100% (20/20). The median time of the procedure was 61 (range 25-122) min. The scheduled stent removal rate was 70% (14/20). Spontaneous dislodgement of the stent was observed on computed tomography in five patients (25.0%). The non-restenosis rate 12 months after the saddle-cross technique was 88.2% (15/17). Procedure-related early adverse events included mild ascending cholangitis in three patients (15.0%) and sepsis in one patient (5.0%). Procedure-related late adverse events included mild ascending cholangitis in three patients (15.0%) and bile duct hyperplasia in one patient (5.0%). CONCLUSIONS The saddle-cross technique performed using two fully covered self-expandable metallic stents resulted in promising long-term stricture resolution with a high technical success rate. Based on these findings, the saddle-cross method can be considered an option for the standard procedure for benign hepaticojejunostomy anastomotic strictures.

Sci Rep 2022; 12:15875. [PMID: 36151222 PMCID: PMC9508112 DOI: 10.1038/s41598-022-19317-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Accepted: 08/26/2022] [Indexed: 11/24/2022] Open
Abstract
To assess the feasibility and safety of a novel 3D-printed biodegradable biliary stent using polycaprolactone (PCL) in an in vivo porcine model. In this animal study using domestic pigs, biodegradable radiopaque biliary stents made of polycaprolactone (PCL) and barium sulfate were produced using 3D printing and surgically inserted into the common bile duct (CBD) of pigs (stent group, n = 12). Another five pigs were allocated to the control group that only underwent resection and anastomosis of the CBD without stent insertion. To check the position and status of the stents and stent-related complications, follow-up computed tomography (CT) was performed every month. The pigs were sacrificed 1 or 3 months after surgery, and their excised CBD specimens were examined at both the macroscopic and microscopic levels. Three pigs (one in the stent group and two in the control group) died within one day after surgery and were excluded from further analysis; the remaining 11 in the stent group and 3 in the control group survived the scheduled follow-up period (1 month, 5 and 1; and 3 months, 6 and 2 in stent and control groups, respectively). In all pigs, no clinical symptoms or radiologic evidence of biliary complications was observed. In the stent group (n = 11), stent migration (n = 1 at 3 months; n = 2 at 1 month) and stent fracture (n = 3 at 2 months) were detected on CT scans. Macroscopic evaluation of the stent indicated no significant change at 1 month (n = 3) or fragmentation with discoloration at 3 months (n = 5). On microscopic examination of CBD specimens, the tissue inflammation score was significantly higher in the stent group than in the control group (mean ± standard deviation (SD), 5.63 ± 2.07 vs. 2.00 ± 1.73; P = 0.039) and thickness of fibrosis of the CBD wall was significantly higher than that of the control group (0.46 ± 0.12 mm vs. 0.21 ± 0.05 mm; P = 0.012). Despite mild bile duct inflammation and fibrosis, 3D-printed biodegradable biliary stents showed good feasibility and safety in porcine bile ducts, suggesting their potential for use in the prevention of postoperative biliary strictures.

Abstract
OBJECTIVE To investigate the long-term outcomes of percutaneous treatment of benign biliary strictures using temporary placement of a retrievable expanded polytetrafluoroethylene (PTFE) covered stent. MATERIALS AND METHODS We retrospectively analyzed the outcomes of 148 patients (84 male and 64 female; age range, 11-92 years) who underwent percutaneous transhepatic placement and removal of a retrievable PTFE-covered stent for the treatment of benign biliary strictures between March 2007 and August 2019 through long-term follow-up. Ninety-two patients had treatment-naïve strictures and 56 had recurrent/refractory strictures. RESULTS Stent placement was technically successful in all 148 patients. The mean indwelling period of the stent was 2.4 months (median period, 2.3 months; range, 0.2-7.7 months). Stent migration, either early or late, occurred in 28 (18.9%) patients. Clinical success, defined as resolution of stricture after completing stent placement and removal, was achieved in 94.2% (131 of 139 patients). The overall complication rate was 15.5% (23 of 148 patients). During the mean follow-up of 60.2 months (median period, 52.7 months; range, 1.6-146.1 months), 37 patients had a recurrence of clinically significant strictures at 0.5-124.5 months after removal of biliary stent and catheter (median, 16.1 months). The primary patency rates at 1, 3, 5, 7, and 10 years after removal of biliary stent and catheter were 88.2%, 70.0%, 66.2%, 60.5%, and 54.5%, respectively. In the multivariable Cox proportional hazard regression analysis, sex, age, underlying disease, relation to surgery, stricture type, biliary stones, history of previous treatment, and stricture site were not significantly associated with the primary patency. CONCLUSION Long-term outcomes suggest that percutaneous treatment of benign biliary strictures using temporary placement of retrievable PTFE-covered stents may be a clinically effective method.

Abstract
OBJECTIVE To describe, assess the feasibility of, and quantify the long-term patency achieved with percutaneous transhepatic biliary dilation using the anastomotic biliary stricture (ABS) oversized balloon dilation technique as a single-step procedure for the treatment of benign anastomotic biliary strictures following hepatobiliary surgery. MATERIALS AND METHODS This was a retrospective, two-center study including 16 consecutive cases of symptomatic benign biliary-enteric strictures. After assessment of the diameter of the bile duct by computed tomography or magnetic resonance imaging, the strictures were dilated with oversized balloons (40-50% larger than the bile duct diameter) and an external biliary-enteric drain was placed. After drain removal, clinical symptoms and laboratory test results were evaluated every three months, whereas follow-up magnetic resonance imaging was performed at 30 days out and follow-up computed tomography was performed at 6 and 12 months out. RESULTS The mean follow-up time was 31.8 ± 8.15 months. Kaplan-Meier-estimated 1-, 2-, and 3-year patency rates were 88.2%, 82.4%, and 82.4%, respectively. There was one major complication-a small dehiscence of the anastomosis-which extended the catheter dwell time. Minor complications occurred in two cases-one small perihepatic hematoma and one segmental thrombosis of the left portal branch-neither of which required further intervention. CONCLUSION The single-step ABS oversized balloon dilation technique is a feasible treatment for benign anastomotic biliary-enteric strictures. The technique appears to be associated with high rates of long-term clinical success and patency.

Abstract
Percutaneous biliary interventions are among the commonly performed nonvascular radiological interventions. Most common of these interventions is the percutaneous transhepatic biliary drainage for malignant biliary obstruction. Other biliary procedures performed include percutaneous cholecystostomy, biliary stenting, drainage for bile leaks, and various procedures like balloon dilatation, stenting, and large-bore catheter drainage for bilioenteric or post-transplant anastomotic strictures. Although these procedures are being performed for ages, no standard guidelines have been formulated. This article attempts at preparing guidelines for performing various percutaneous image-guided biliary procedures along with discussion on the published evidence in this field.

Abstract
Benign biliary strictures are often due to a variety of etiologies, most of which are iatrogenic. Clinical presentation can vary from asymptomatic disease with elevated liver enzymes to obstructive jaundice and recurrent cholangitis. Diagnostic imaging methods, such as ultrasound, multidetector computed tomography, and magnetic resonance imaging (cholangiopancreatography), are used to identify stricture location, extent, and possible source of biliary obstruction. The management of benign biliary strictures requires a multidisciplinary team approach and include endoscopic, percutaneous, and surgical interventions. Percutaneous biliary interventions provide an alternative diagnostic and therapeutic approach, especially in patients who are not amenable to endoscopic evaluation. This review provides an overview of benign biliary strictures and percutaneous management by interventional radiologists. Diagnostic evaluation with percutaneous transhepatic cholangiography and treatment options, including biliary drainage, balloon dilation, retrievable/biodegradable stents, and other innovative minimally invasive options, are discussed.

Abstract
PURPOSE To retrospectively compare the safety and efficacy of a covered self-expandable metal stent (CSEMS) with a transhepatic fixation string and a large-bore catheter for benign biliary anastomotic stricture after hepatobiliary surgery. MATERIALS AND METHODS From March 2012 to June 2017, 49 patients with benign biliary anastomotic strictures, untreatable with endoscopy, were included. Twenty-three patients (catheter group) were treated with a large-bore catheter (with progressive catheter upsizing to 16-18 Fr), whereas 26 patients (stent group) were treated by CSEMS (10-mm stent) placement. Technical success, clinical success, primary patency, recurrent strictures, complication rate, and catheter or stent indwelling time were compared between the groups. RESULTS Technical success and clinical success were achieved in all patients. In the stent group, stent retrieval was successful in all patients. The overall complication rate was 24.5% (catheter group vs. stent group, 30.4% vs. 19.2%; P = .363). Stent migration occurred in 1 patient during follow-up (1/26, 3.8%). The mean indwelling time was 10.3 ± 3.0 months (range, 8-16 months; median, 10 months) in the catheter group and 4.0 ± 1.2 months (range, 3-7 months; median, 4 months) in the stent group (P < .001). Recurrent strictures occurred in 10 (43.5%) patients in the catheter group and 4 (15.4%) patients in the stent group (P = .030). The 1- and 3-year primary patency rates were 82.6% and 69.3% in the catheter group and 92.3% and 84.4% in the stent group (P = .042). CONCLUSIONS Percutaneous placement of a retrievable CSEMS showed superior intermediate-term outcomes over a large-bore catheter in patients with benign biliary anastomotic strictures.

Abstract
AIM To evaluate the technical feasibility and safety of percutaneous recanalisation of benign postoperative hepaticojejunostomy strictures using the reverse end of a microwire. MATERIALS AND METHODS Twenty-one patients with benign postoperative hepaticojejunostomy strictures that had failed to recanalise following management with conventional percutaneous techniques from January 2012 to March 2019 were included in the study. The stricture was punctured by the reverse end of a microwire. Subsequently, serial balloon dilatation and covered stent placement was performed. Technical as well as clinical success, complications, and patency of the hepaticojejunostomy were evaluated. RESULTS Technical success was achieved in 19 of 21 (90.5%) patients. The mean number of treatment sessions was 1.2 (range, 1-2). The obstructive symptoms were resolved within 3 days after the procedure in 19 patients (100%). There were no major complications. The 1-year and 3-year patency rates were 76.9% and 61.5%, respectively. CONCLUSION Percutaneous recanalisation using the reverse end of a microwire is technically feasible and safe in the treatment of benign postoperative hepaticojejunostomy strictures. This technique is useful when the conventional percutaneous technique cannot be used to cross the stricture.

Abstract
OBJECTIVES Benign strictures of the bile duct may be difficult to treat endoscopically due to altered bowel anatomy. Furthermore, recurrence of stenosis and symptoms remains high. The aim of the Spanish Prospective Registry BiELLA study was to investigate the safety and efficacy of absorbable stents in the treatment of benign biliary strictures and their outcomes on the medium and long-term follow-up. METHODS A prospective, multicenter, observational, non-randomized study (the BiELLA study) was conducted from January 2014 to September 2018. One hundred fifty-nine patients with benign biliary strictures, mostly postsurgical, were enrolled for implantation of absorbable biliary stents in the 11 participating Spanish tertiary hospitals. The average patient follow-up was 45.4 ± 15.9 months (range, 12-60 months). The follow-up data included symptoms, biochemical parameters, and ultrasound images at 1, 6, and 12 months and then yearly for up to 60 months. RESULTS The immediate technical and clinical success rates were 100%. In all patients, stent placement resulted in improvement of clinical symptoms and biochemical parameters. The primary mean patency for stent was 86.7, 79.6, and 78.9% at 12, 36, and 60 months, respectively (95% CI). Biliary restenosis and occlusion occurred in 40 (26.6%) patients. Of the 40 patients, 18 (12%) patients were treated with a second stent and 22 (14.6%) patients had operative repair of the recurrent strictures. There were no major complications associated with stent implantation. CONCLUSIONS Implantation of an absorbable polydioxanone biliary stent is safe and effective for treatment of benign biliary strictures refractory to balloon dilatation or other biliary intervention. KEY POINTS • Percutaneous implantation of biodegradable prostheses for the treatment of benign postsurgical biliary strictures is a safe and effective procedure. • More than 75% of the patients presented patency of the stented biliary tree at 5 years follow-up. • Absorbable stents improved clinical symptoms and signs (jaundice, itching, fever), and laboratory parameters in a few days after stent placement.

Abstract
Background and Objectives: The management of benign biliary stricture in patients with altered anatomy secondary to surgery is challenging. Percutaneous transhepatic biliary drainage (BD) represents the standard therapy for benign biliary stricture, but it is associated with nontrivial morbidity rates. Despite the increasing application of guided BD (EUS-BD) for the management of malignant obstruction, its role in patients with benign biliary stricture is limited. This retrospective study aimed to evaluate the feasibility, safety, and clinical effectiveness of EUS-BD with multiple transanastomotic plastic stent treatment in patients with benign biliary stricture. Materials and Methods: This study included consecutive patients who underwent EUS-BD for benign biliary stenosis at our center. EUS-BD with fully covered self-expandable metal stent placement was performed first. When feasible, the stricture was treated by balloon dilation with the placement of a transanastomotic double-pigtail plastic stent. Scheduled procedures were repeated to remove the metal stent and replace the plastic stent to treat the stenosis. Technical success and adverse events (AEs) were assessed. Results: Twelve patients underwent EUS-BD for benign biliary strictures. Procedural and clinical successes were achieved in all patients (100%). Multistenting treatment was performed in 10/12 patients (77%). The median number of stents inserted, maximum number of stents placed, and median time of retreatment were 2.4 (range: 1–4), 4, and 3.4 (range: 1–7), respectively. In total, 4/12 patients (33.3%) developed AEs that required endoscopic interventions (Clavien-Dindo Grade III). Conclusions: EUS-BD with the placement of multiple trans-stenosis plastic stents is a safe, feasible, and well-tolerated alternative for the management of benign biliary stricture in patients with surgery-altered anatomy. Long-term follow-up is necessary to support our results.

Abstract
We aimed to evaluate the feasibility and safety of long-term balloon indwelling technique for the treatment of single benign biliary stricture. Five patients with single benign biliary stricture were included from December 2014 to November 2016. The patients were three men and two women with a mean age of 50 years (range, 30-65 years). A balloon catheter was inserted into the drainage catheter and emerged through the side hole of the catheter so that the balloon and drainage catheters could be placed together at the stricture site. Follow-up fluoroscopic examination was performed at least once every 2 weeks to evaluate the adequacy of expansion and location of the balloon. The balloon was reinflated at each session, and then removed after an approximately two-month indwelling period. The catheters used were 10-16 French and the diameter of indwelling balloons were 4-8 mm. The primary technical and clinical success rates were 100%. Maintenance of the balloon location was achieved in 25 of 26 follow-up fluoroscopic examinations (mean, 5.2 times per patient) with a rate of 96.1%. The mean follow-up period after successful removal of the balloon was 542.2 days (range, 93-1042 days), and there were no recurrences in the five cases. The long-term balloon indwelling technique is a good way to induce maximal dilatation at the stricture site without large diameter skin and subcutaneous tract dilatation and can be successfully used for single benign biliary stricture.

Abstract
Biliary strictures can be broadly classified as benign or malignant. Benign biliary strictures are most commonly iatrogenic in nature and are a consequence of hepatobiliary surgery. Cholangiocarcinoma and adenocarcinoma of the pancreas are the most common causes of malignant biliary obstruction. This article reviews state-of-the-art minimally invasive techniques used to manage these strictures. In addition, the roles of (a) recently introduced biodegradable biliary stents in the management of benign biliary strictures and (b) intraprocedural imaging and navigation tools, such as cone-beam CT, in percutaneous reconstruction of the biliary-enteric anastomosis are discussed.

Percutaneous treatment of benign bilioenteric anastomotic strictures: temporary covered stent placement versus balloon dilatation. Eur Radiol 2018; 29:2690-2697.

Abstract
OBJECTIVES To compare percutaneous temporary covered stent placement with balloon dilatation in the treatment of benign stricture of bilioenteric anastomosis. METHODS From November 2004 to August 2017, 56 patients with benign bilioenteric anastomotic strictures underwent percutaneous transhepatic treatment. A temporary covered stent designed for spontaneous migration was placed in 23 patients (stent group). Balloon dilatation was performed in 33 patients (balloon group). The technical success, percutaneous transhepatic biliary drainage (PTBD) indwelling times, stent indwelling times and patency rates were retrospectively compared between the two groups. RESULTS Technical success was achieved in all patients in the stent group and in 96.8% (32/33) of patients in the balloon group. All stents spontaneously migrated into the jejunum, and stent indwelling times were 3-9 months (median, 6 months). The PTBD indwelling time was shorter for the stent group than for the balloon group (median, 7 vs. 71 days, p = 0.001). Recurrent strictures occurred more frequently in the balloon group than in the stent group (54.5% vs. 13.0%, p = 0.002; hazard ratio 3.7). The 1- and 3-year primary patency rates were 90.2% and 84.9% for the stent group and 75.1% and 52.8% for the balloon group, respectively (p = 0.04). CONCLUSIONS Percutaneous temporary covered stenting is an effective treatment in patients with benign bilioenteric anastomotic strictures. It provides longer patency and shorter PTBD indwelling time compared with balloon dilatation. KEY POINTS • A temporary covered stent designed for spontaneous migration is a feasible and effective treatment for patients with benign bilioenteric anastomotic strictures. • Percutaneous temporary covered stents provide longer patency and shorter drainage catheter indwelling time compared with conventional balloon dilatation. • A covered stent with flared ends spontaneously migrated after 3-9 months.

Abstract
OBJECTIVES To analyze the safety and efficacy of percutaneous placement of coated self-expanding metallic stents (SEMS) in patients with biliary leaks. MATERIAL AND METHODS This ethics committee at our center approved this study. We retrospectively reviewed all coated SEMS placed between October 2008 and September 2015. We analyzed patient-related factors such as the primary underlying disease, prior hepatic procedures, and clinical outcome. We evaluated the location, the number and type of leak (anastomotic or non-anastomotic), and the characteristics of the interventional procedure (number of stents deployed, location of the stents, technical success, and primary functionality). We recorded the complications registered. RESULTS We studied 14 patients (11 men and 3 women). The mean follow-up period was 375.5 days (range 15-1920 days). Leaks were postsurgical in 12 patients. One patient developed an arteriobilioportal fistula. In another, the biliary leak occurred secondary to the rupture of the common bile duct after ERCP. A total of 23 coated SEMS were placed, including 21 Fluency® stents (Bard, Tempe, AZ, USA) and 2 Wallflex® stents (Boston Scientific, Galway, Republic of Ireland). The technical success of the procedure was considered total in 11 (78.6%) patients, partial in 2 (14.3%) patients, and null in 1 (7.2%) patient. The clinical outcome was good in 13 of the 14 patients. The mean period of primary functionality of the coated SEMS was 331 days (range 15-1920 days). No major complications were observed in 11 (78.6%) patients. CONCLUSIONS Percutaneous placement of coated SEMS for the treatment of benign biliary leaks is safe and efficacious, with a high rate of technical and clinical success and a moderate rate of complications.

Abstract
Bilioenteric anastomosis strictures are a serious complication of biliary surgery, and often result in recurrent cholangitis, choledocholithiasis, biliary cirrhosis, and hepatic failure. Bilioenteric reconstructive surgery is the standard treatment of choice for such complications. However, percutaneous transhepatic cholangioscopy (PTCS), also known as per-oral endoscopic-guided intervention, is a less invasive procedure that is becoming an increasingly popular alternative. This review describes the PTCS procedure (including the preparation process), as well as the diagnostic and therapeutic role of PTCS in bilioenteric anastomosis strictures.

Abstract
OBJECTIVE To describe techniques for endoscopic retrograde cholangiography (ERC) and endoscopic retrograde biliary stenting of the common bile duct (CBD) for minimally invasive treatment of extrahepatic bile duct obstruction (EHBDO) in dogs. DESIGN Experimental study and clinical report. ANIMALS 7 healthy research dogs and 2 canine patients. PROCEDURES ERC and endoscopic retrograde biliary stenting were performed in healthy purpose-bred research dogs and client-owned dogs with a diagnosis of EHBDO that underwent an attempted biliary stent procedure. Research dogs were euthanized after completion of the procedure and underwent necropsy. With dogs under general anesthesia, the pylorus was cannulated with a side-view duodenoscope, and the duodenum was entered. The major duodenal papilla (MDP) and minor duodenal papilla were then identified, and the MDP was cannulated. Endoscopic retrograde cholangiography and endoscopic retrograde biliary stenting were attempted with the aid of endoscopy and fluoroscopy in all dogs. Procedure time, outcome for duodenal and MDP cannulation, and success of stent placement were recorded. RESULTS Endoscopic retrograde cholangiography was successfully performed in 5 of 7 research dogs and in 1 of 2 patients. Biliary stenting was achieved in 4 of 7 research dogs and 1 of 2 patients, with a polyurethane (n = 4) or self-expanding metallic stent (1). One patient had a mass such that visualization of the MDP was impossible and no attempt at biliary cannulation could be made. After placement, stent patency was documented by means of contrast cholangiography and visualization of biliary drainage into the duodenum intra-operatively. No major complications occurred during or after the procedure in any patient. Follow-up information 685 days after stent placement in 1 patient provided evidence of biliary patency on serial repeated ultrasonography and no evidence of complications. CONCLUSIONS and CLINICAL RELEVANCE ERC and endoscopic retrograde biliary stenting were successfully performed in a small group of healthy dogs and 1 patient with EHBDO, but were technically challenging procedures. Further investigation of this minimally invasive technique for the treatment of EHBDO in dogs is necessary before this may be considered a viable alternative to current treatment methods.

Abstract
BACKGROUND Procedure-related complications of percutaneous transhepatic biliary drainage (PTBD) have been well documented in the literature. However, relatively restricted data are available concerning drainage-related complication rates in long-term PTBD therapy. The present retrospective study evaluated the extent and the nature of drainage complications during PTBD therapy and associated risk factors for these complications. PATIENTS AND METHODS Between June 1997 and May 2007, a total of 385 patients with PTBD were identified by analyzing the PTBD database and hospital charts, with a total of 2468 percutaneous biliary drainages being identified. RESULTS Among the identified patients, 243 (63%) had malignant and 142 (37%) had benign bile duct strictures. At least 1 drainage-related complication was observed in 40% of the patients. With respect to the total number of drains, prosthesis complications occurred in 23%. Occlusion, dislocation, and cholangitis were the most common complications observed during PTBD therapy. Risk factors for cholangitis and occlusion were malignant disease, prior occurrence of complications, and bilateral drainage. Proximal stenosis of the biliary system was close to significant. CONCLUSIONS Drainage-related complications are a major problem in PTBD therapy. The risk factors for occlusion and cholangitis discovered in this study can help to refine individual strategies to reduce the rate of these drainage complications.

Abstract
BACKGROUND Although the use of polytetrafluoroethylene (PTFE)-covered biliary stents has proven to be feasible for the treatment of benign and malignant biliary disease, less is known regarding the outcomes of percutaneous placement of a covered stent in patients with malignant duodenobiliary obstruction. PURPOSE To investigate the technical and clinical efficacy of the percutaneous placement of a PTFE-covered biliary stent in patients with malignant duodenobiliary obstruction. MATERIAL AND METHODS From April 2007 to September 2012, the medical records of 45 consecutive patients with malignant duodenobiliary obstruction were retrospectively reviewed. All percutaneous biliary stent deployment was performed using PTFE-covered stents, whereas duodenal stent insertion was performed either fluoroscopically or endoscopically using covered or uncovered stents. RESULTS Biliary stent deployment was technically successful in all patients. None of the stents migrated after deployment. Procedure-related minor complications, including self-limiting hemobilia, occurred in three (7%) patients. Successful internal drainage was achieved in 39 (87%) of the 45 patients. The median survival time after biliary stent placement was 62 days (95% confidence interval, 8-116 days), and the cumulative stent patency rates at 1, 3, 6, and 12 months were 96%, 92%, 75%, and 38%, respectively. The causes of biliary stent dysfunction included stent occlusion caused by a subsequently inserted duodenal stent (n = 7), food impaction (n = 3), and sludge incrustation (n = 1). One patient developed acute cholecystitis 131 days after biliary stent placement and underwent percutaneous transhepatic gallbladder drainage. CONCLUSION Percutaneous insertion of a PTFE-covered stent is a safe and effective method for palliative treatment of patients with malignant duodenobiliary obstruction. If possible, subsequent biliary stent insertion is preferable in order to prevent possible biliary stent dysfunction caused by subsequent insertion of a duodenal stent.

Abstract
BACKGROUND Percutaneous balloon dilation of benign biliary stricture has been the most widely used alternative to endoscopic treatment; however, the rate of recurrence has varied from 15 to 44 %. Recently, several investigators have reported that percutaneous transhepatic placement of retrievable covered stents is feasible for the treatment of benign biliary strictures. However, these studies had only a small number of patients and had short follow-up periods. AIM The purpose of this study was to investigate the mid-term outcomes of a retrievable covered stent for treatment of benign biliary strictures. METHODS We retrospectively assessed 68 patients who underwent percutaneous transhepatic placement and removal of a retrievable covered stent between March 2007 and November 2012, for treatment of benign biliary strictures. Forty-two patients had not previously undergone interventional treatment, whereas 26 had recurrent or refractory strictures despite previous percutaneous procedures. RESULTS Placement of the retrievable covered stents was technically successful in all patients. Stent migration occurred in 11 (16.2 %) patients. The mean indwelling period of drainage catheter and stent were 5.8 months (range, 3-22.5 months) and 3 months (range, 2-6.5 months), respectively. Clinical success was achieved in 59 (86.8 %) patients. During the mean follow-up of 36 months (range, 8.5-65 months), 12 (20 %) of 60 patients had recurrence of clinically significant strictures. The primary patency rates at 1, 2, 3, 4, and 5 years were 91, 89, 76, 68, and 68 %, respectively. CONCLUSION Mid-term outcomes suggested that percutaneous treatment of benign biliary strictures using a retrievable covered stent was a clinically effective method.

Abstract
The optimal treatment for patients with biliary obstruction varies depending on the underlying cause of the obstruction, the clinical condition of the patient, and anticipated long-term effects of the procedure performed. Endoscopic and image-guided procedures are usually the initial procedures performed for biliary obstructions. Various options are available for both the radiologist and endoscopist, and each should be considered for any individual patient with biliary obstruction. This article provides an overview of the current status of radiologic procedures performed in the setting of biliary obstruction and describes multiple clinical scenarios that may be treated by radiologic or other methods. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances in which evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment.

Abstract
Background Benign biliary postoperative stenoses and biliary leaks and fistulas usually occur due to injury after laparoscopic cholecystectomy, gastric or hepatic resection, bilio-enteric anastomoses and after liver transplantation. In most of the cases a new surgical intervention is not possible and the percutaneous trans-hepatic approach is of paramount importance in the diagnosis and treatment of the problem. This review aims to highlight the spectrum of percutaneous cholangiographic findings and methods of treatment of postoperative benign biliary stenoses and biliary leaks and fistulas. In the case of stenosis, dilation of the narrow tract is the usually the first approach, whereas in the case of leaks and fistulas bile diversion with drainage is usually attempted in order to seal the fistulous tract. However, a great variety of combination of materials and techniques may be used on a “case-by case” approach Methods A selection of cases of benign biliary postoperative stenoses and biliary leaks and fistulas that were managed percutaneously are presented and the most common lines of approach are discussed. Conclusion The imaging spectrum of percutaneous treatment of benign biliary postoperative stenoses and biliary leaks and fistulas is presented in order to aid interpretation and management with image guided procedures. Teaching Points • Treatment of benign biliary stenosis is performed with cholangioplasty and stents. • The main goal of fistula treatment is to divert the bile away from the site of bile wall defect. • Drain collection and tract embolisation are the other options for bile leak percutaneous treatment.

Abstract
PURPOSE We sought to evaluate the feasibility and efficacy of percutaneous treatment of early postoperative biliary complications. The primary aims were to evaluate clinical and technical success and complications and perioperative mortality, and secondary aims were to evaluate treatment duration and recurrence rate. MATERIALS AND METHODS Between March 2007 and March 2010, 75 patients (42 men and 33 women; age range, 17-88 years; mean age, 60.8 years) underwent interventional radiology procedures to treat early postoperative biliary complications of biliary and pancreatic-duodenal surgery with biliodigestive anastomosis (37.7%), laparoscopic cholecystectomy (30.6%), hepatic resection (21.1%) and several other surgical procedures (10.6%). Complications included fistulas (73%), stenoses (20%) and complete bile duct transections (7%). RESULTS Interventional radiology achieved complete clinical success in 74 cases (85.9%) and in particular in 95.2% of fistulas, 76.5% of stenoses and 33.3% of complete bile duct transections. Mean indwelling catheter time was 34.9 days, with an average of 4.1 procedures. There were two cases of severe haemobilia (2.3%). Minor complications occurred in 7% of cases. Perioperative mortality rate was 1.2% and overall recurrence rate 6.7% (range, 1-18 months; mean, 10 months), with recurrences occurring predominantly in stenoses. All patients were retreated successfully. CONCLUSIONS Percutaneous procedures are feasible, effective and safe for treating early postoperative biliary complications. They provide a valuable alternative to presendoscopy, which is precluded in many of these patients, and to surgery, which has higher morbidity and mortality rates.

Abstract
PURPOSE To investigate the technical and clinical safety and efficacy of percutaneous Y-configured covered stent placement in patients with malignant hilar biliary obstruction. MATERIALS AND METHODS This prospective, pilot study enrolled 20 consecutive patients with malignant hilar biliary obstructions from October 2009 to December 2010. All patients were treated by percutaneous transhepatic placement of partially expanded polytetrafluoroethylene (ePTFE)-covered stents in a Y configuration. RESULTS Bilateral Y-configured covered stent deployment was technically successful in all 20 patients. Minor procedure-related complications occurred in four (20%) patients including self-limiting hemobilia in one patient and rapidly resolving cholangitis in three patients. Successful internal drainage was achieved in 18 (90%) of 20 patients. Mean serum bilirubin level, which was 12.6 mg/dL ± 5.1 before drainage, decreased significantly to 2.5 mg/dL ± 4.5 1 month after stent placement (P < .001). Median patient survival and stent patency times were 218 days (95% confidence interval [CI] 112-324 days) and 375 days (95% CI 55-695 days). Seven (35%) patients presented with stent occlusion, in six owing to sludge incrustation and in one owing to tumor overgrowth, and required repeat percutaneous transhepatic biliary drainage (PTBD). Tumor ingrowth, acute cholecystitis, or stent migration was not observed in any patient. CONCLUSIONS Preliminary results suggest that percutaneous palliative treatment of malignant hilar biliary obstruction with Y-configured covered stents is safe and clinically effective in achieving internal biliary drainage. Y-configured, ePTFE-covered stents can also prevent tumor ingrowth without functional occlusion of hepatic segmental bile ducts.
