Abstract
UNLABELLED We sought to determine factors that predict the successful surgical repair of biliary complications after adult living donor liver transplantation (ALDLT). METHODS Records of 82 consecutive ALDLT right lobe recipients were reviewed. Operations were performed on 19 recipients for biliary complications. Post-operative biliary complications were analyzed. Fisher's exact test was used to identify variables that correlated with successful surgical repair. RESULTS A total of 29 recipients had biliary complications, of which 19 had a surgical repair. The five recipients, operated on for a stricture without history of leaks, did not develop further complications. However, nine of 14 with a history of a leak developed further complications after surgical repair (p-value = 0.044). All five who presented with a biliary complication more than 100 d after transplant had successful surgical repair; however, nine out of 13 who presented within 57 d had additional complications after repair. CONCLUSIONS Operations for strictures after ALDLT are more successful than operations for leaks. Recipients with isolated biliary strictures after ALDLT can be managed surgically; however, recipients with history of a leak often require additional interventions after surgical repair.

Abstract
AIMS To present our case series of fully covered self-expandable metallic stents (FCSESs) placed to treat biliary stenosis after liver transplantation and leakage after failure of plastic stenting. MATERIALS AND METHODS We retrospectively reviewed the courses of patients who had undergone liver transplantation with a biliary complication that was treated by an FCSES installed by endoscopic retrograde cholangiopancreatography. We evaluated the following variables: gender, age, indication for transplantation, time between transplant and diagnosis of the complication, number of plastic stents placed before the FCSES, and procedure-related complications. RESULTS From April 2008 to March 2010, 11 patients who had undergone a duct-to-duct anastomosis suffered posttransplant biliary stenosis or leakage with failure of endoscopic treatment using a plastic biliary stent: Namely, eight cases of stenosis and three of biliary leaks. Three patients underwent a papillotomy to place the FCSES, with no significant morbidity. No severe complications were observed after the endoscopic treatments; two patients developed mild pancreatitis; two, hyperamylasemia; and one, mild biliary sepsis. We removed the FCSES after a mean of 280 (range=173-310) days. Five patients lost the FCSES spontaneously. One patient underwent a choledocojejunostomy and two are waiting biliary surgery. CONCLUSION We avoided cholangiojejunostomy in 6/9 cases (not including the two deaths). Papillotomy did not engender a greater morbidity. The spontaneous loss of the stent is a problem that need to be resolved.

Abstract
Biliary reconstruction remains common in postoperative complications after liver transplantation. A systematic search was conducted on the PubMed database and 61 studies of retrospective or prospective institutional data were eligible for this review. The study comprised a total of 14,359 liver transplantations. The overall incidence of biliary stricture was 13%; 12% among deceased donor liver transplantation (DDLT) patients and 19% among living donor liver transplantation (LDLT) recipients. The overall incidence of biliary leakage was 8.2%, 7.8% among DDLT patients and 9.5% among LDLT recipients. An endoscopic strategy is the first choice for biliary complications; 83% of patients with biliary stricture were treated by endoscopic modalities with a success rate of 57% and 38% of patients with leakage were indicated for endoscopic biliary drainage. T-tube placement was not performed in 82% of duct-to-duct reconstruction. The incidence of biliary stricture was 10% with a T-tube and 13% without a T-tube and the incidence of leakage was 5% with a T-tube and 6% without a T-tube. A preceding bile leak and LDLT procedure are accepted risk factors for anastomotic stricture. Biliary complications remain common, which requires further investigation and the refinement of reconstruction techniques and management strategies.

Abstract
Biliary complications occur in 5-25% of patients after liver transplantation and represent a major source of morbidity in this group of individuals. The major risk factor for most of these complications is ischemia of the bile tree usually due to obstruction or vascular insufficiency of the hepatic artery. The most common complications include biliary strictures (anastomostic and nonanastomotic), bile leaks, and biliary filling defects. The initial diagnostic approach starts with a high index of suspicion along with an abdominal ultrasound and Doppler exam. Magnetic resonance imaging is highly sensitive and is usually reserved for confirmation. The vast majority of these complications can be successfully treated with endoscopic retrograde cholangiography, however if this procedure cannot be performed a percutaneous approach or surgery is recommended. Nonanastomotic strictures and living donor recipients present a less favorable response to endoscopic management. This review focuses on the current diagnostic and therapeutic approaches for the management of biliary complications after liver transplantation.

Abstract
Postoperative biliary strictures are the most common cause of benign biliary stricture in Western countries, secondary to either operative injury or bile duct anastomotic stricture following orthotopic liver transplantation (OLT). Surgery or endoscopic interventions are the mainstay of treatment for benign biliary strictures. We aim to report the outcome of 2 patients with refractory anastomotic biliary stricture post-OLT, who had successful temporary placement of a prototype removable covered self-expandable metal stent (RCSEMS). These 2 patients (both men, aged 44 and 53 years) were given temporary placement of a prototype RCSEMS (8.5 Fr gauge delivery system, 8 mm × 40 mm stent dimensions) in the common bile duct across the biliary stricture. There was no morbidity associated with stent placement and removal in these 2 cases. Clinical parameters improved after the RCSEMS placement. Long-term biliary patency was achieved in both the patients. No further biliary intervention was required within 14 and 18 mo follow-up after stent removal.

Abstract
Complications of the biliary tract are an important cause of morbidity and mortality after liver transplantation. The most frequent complications are anastomotic biliary tract strictures, bile leaks, and bile duct stones. The estimated incidence of these complications ranges between 5% and 25%, although rates have been decreasing in recent years. Most complications can be managed successfully with endoscopic retrograde cholangiography. This article reviews the various biliary complications after liver transplantation (both deceased donor and living-related donor) and their endoscopic management.

Abstract
BACKGROUND The optimal endoscopic protocol for treating postorthotopic liver transplantation (OLT) anastomotic biliary strictures (ABSs) has not been established. OBJECTIVE To review the technique and outcomes of endoscopic retrograde cholangiopancreatography (ERCP) with maximal stenting for post-OLT ABSs at our institution. DESIGN Retrospective study. SETTING Tertiary-care center. PATIENTS Eighty-three patients with a diagnosis of ABS. INTERVENTIONS ERCP with balloon dilation and maximal stenting. MAIN OUTCOME MEASUREMENTS Stricture resolution, stricture recurrence, and complication rates. RESULTS Of 83 patients, 69 completed treatment, of whom 65 (94%) achieved resolution and 4 (6%) required hepaticojejunostomy (HJ). The remaining 14 patients who did not achieve a study endpoint were excluded (9 deaths or redo OLT unrelated to biliary disease, and 5 without follow-up). Comparing the resolution group and the HJ group, there were, respectively, 8.0 and 3.5 total stents (P = .021), 2.5 and 1.3 stents per ERCP (P = .018) (maximum = 9), 4.2 and 2.8 ERCPs (P = .15), and 20 and 22 months from OLT to ABS diagnosis (P = .19). There were 2 cases of ERCP pancreatitis (0.7%) and 2 cases of periprocedural bacteremia of 286 total ERCPs and no episodes of cholangitis caused by stent occlusion. In a median follow-up of 11 months (range 0-39), 2 (3%) patients had ABS recurrence that was successfully re-treated with ERCP. A multivariate Cox model demonstrated that treatment success was directly related to the number of stents used in total and per ERCP. LIMITATIONS Retrospective study, single endoscopist. CONCLUSIONS Our maximal stenting protocol for ABSs is effective, safe, rarely associated with ABS recurrence, and conducive to less frequent stent exchange and therefore fewer ERCPs compared with conventional treatment.

Abstract
BACKGROUND Biliary strictures are a serious complication after liver transplantation. Endoscopic and percutaneous transhepatic procedures have gained an increasing potential for the management of this problem. OBJECTIVE Long-term follow-up of endoscopic and/or percutaneous transhepatic therapy of biliary strictures after liver transplantation was evaluated. PATIENTS AND METHODS Between January 1996 and December 2007, 47 patients with biliary stricture after liver transplantation were identified by analysing the endoscopic database, hospital charts and cholangiograms. Long-term follow-up was evaluated using cholangiograms, transabdominal ultrasound, laboratory parameters and physical examination. RESULTS The type of biliary stricture after liver transplantation was subdivided into anastomotic stricture (n = 29), non-anastomotic stricture (n = 14) and bilioenterostomy stricture (n = 4). Of the patients, 38/47 were treated by endoscopic procedures (ERCP), and 9/47 patients were treated by percutaneous transhepatic procedures (PTBD). In 2 of 47 patients combined approaches (rendezvous technique) were performed. Overall, 23/29 patients in the anastomotic group, 12/14 patients in the non-anastomotic group, and 3/4 patients in the bilioenterostomy group had successfully completed endoscopic and/or percutaneous transhepatic therapy. Biliary drainage could be respectively terminated after median 9 (1-83), 11 (1-89) and 10 (4-14) months. CONCLUSIONS Endoscopic as well as percutaneous transhepatic approaches in combination or as monotherapy are effective in the management of anastomotic and non-anastomotic strictures after liver transplantation.

Abstract
Background Benign biliary strictures may be a consequence of surgical procedures, chronic pancreatitis or iatrogenic injuries to the ampulla. Stents are increasingly being used for this indication, however it is not completely clear which stent type should be preferred. Methods A systematic review on stent placement for benign extrahepatic biliary strictures was performed after searching PubMed and EMBASE databases. Data were pooled and evaluated for technical success, clinical success and complications. Results In total, 47 studies (1116 patients) on outcome of stent placement were identified. No randomized controlled trials (RCTs), one non-randomized comparative studies and 46 case series were found. Technical success was 98,9% for uncovered self-expandable metal stents (uSEMS), 94,8% for single plastic stents and 94,0% for multiple plastic stents. Overall clinical success rate was highest for placement of multiple plastic stents (94,3%) followed by uSEMS (79,5%) and single plastic stents (59.6%). Complications occurred more frequently with uSEMS (39.5%) compared with single plastic stents (36.0%) and multiple plastic stents (20,3%). Conclusion Based on clinical success and risk of complications, placement of multiple plastic stents is currently the best choice. The evolving role of cSEMS placement as a more patient friendly and cost effective treatment for benign biliary strictures needs further elucidation. There is a need for RCTs comparing different stent types for this indication.

Abstract
After liver transplantation, the most common biliary complication is the anastomotic stricture, which is followed by biliary leakage. Studies have focused on the endoscopic treatment of biliary complications in transplanted patients with duct-to-duct reconstruction, showing a success rate of 70% to 80% after orthotopic liver transplantation and of 60% after living-related liver transplantation. Once the endoscopic approach fails, surgical treatment with a Roux-en-Y choledochojejunostomy is the sole alternative treatment. The aim of this prospective observational study was to analyze the efficacy and safety of fully covered self-expandable metallic stents for the treatment of posttransplant biliary stenosis and leaks in patients in whom conventional endoscopic retrograde cholangiopancreatography (ERCP) failed. From January 2008 to January 2009, 16 patients met the criteria of endoscopic treatment failure, and instead of surgery, a fully covered stent was placed. All patients had at least 6 months of follow-up (mean follow-up of 10 months). After removal, 14 patients showed immediate resolution of both the biliary stenosis and leak. After a mean of 10 months of follow-up, only 1 patient showed biliary stenosis recurrence. No major complications occurred in any of the patients, except for stent migration in 6 patients, although these presented with no clinical consequences. In conclusion, in patients not responding to standard endoscopic treatment, the placement of fully covered metal stents is a valid alternative to surgery. A cost analysis should be performed in order to evaluate whether to treat transplanted patients suffering from biliary complications with covered self-expandable metallic stent placement as first-line therapy.

Abstract
Bile duct strictures remain a major source of morbidity after orthotopic liver transplantation (OLT). Biliary strictures are classified as anastomotic or non-anastomotic strictures according to location and are defined by distinct clinical behaviors. Anastomotic strictures are localized and short. The outcome of endoscopic treatment for anastomotic strictures is excellent. Non-anastomotic strictures often result from ischemic and immunological events, occur earlier and are usually multiple and longer. They are characterized by a far less favorable response to endoscopic management, higher recurrence rates, graft loss and need for retransplantation. Living donor OLT patients present a unique set of challenges arising from technical factors, and stricture risk for both recipients and donors. Endoscopic treatment of living donor OLT patients is less promising. Current endoscopic strategies for biliary strictures after OLT include repeated balloon dilations and placement of multiple side-by-side plastic stents. Lifelong surveillance is required in all types of strictures. Despite improvements in incidence and long term outcomes with endoscopic management, and a reduced need for surgical treatment, the impact of strictures on patients after OLT is significant. Future considerations include new endoscopic technologies and improved stents, which could potentially allow for a decreased number of interventions, increased intervals before retreatment, and decreased reliance on percutaneous and surgical modalities. This review focuses on the role of endoscopy in biliary strictures, one of the most common biliary complications after OLT.

Abstract
Recurrent hepatitis C (HCV) and biliary complications (BC) are major causes of post liver transplant morbidity and mortality. The impact of these complications may be additive or synergistic. We performed a retrospective cohort study to analyze the effects of HCV and BC on all patients transplanted at two institutions over 6 years. BC was defined by imaging findings in the setting of abnormal liver function tests that required intervention. The primary outcomes were graft and patient survival over a mean 3.4 years. 709 patients (619 deceased, 90 living donor) were included, 337 with HCV and 372 without. BC was diagnosed more frequently in patients with HCV, 26% versus 18% (p = 0.008). One-year and overall patient and graft survival were significantly lower in patients with HCV, but BC impacted only 1-year graft survival. The combination of BC and HCV had no additional impact on survival or fibrosis rates on 1-year protocol biopsies. Multivariate analysis revealed HCV (HR 2.1) and HCC (HR 1.9) to be independent predictors of mortality. Since BC are diagnosed more frequently in HCV patients and only affect early graft loss, it is likely that recurrent HCV rather than BC accounts for the majority of adverse graft outcomes.

Abstract
Biliary tract complications are an important source of morbidity after liver transplantation, and present a challenge to all involved in their care. With increasing options for transplantation, including living donor and split liver transplants, the complexity of these problems is increasing. However, diagnosis is greatly facilitated by modern noninvasive imaging techniques. A team approach, including transplant hepatology and surgery, interventional endoscopy and interventional radiology, results in effective solutions in most cases, such that operative reintervention or retransplantation is rarely required.

Abstract
Endoscopic intervention is considered to be the primary treatment for biliary stricture after adult living donor liver transplantation (LDLT) with duct-to-duct biliary reconstruction. The aim of this study was to investigate the risk factors of biliary stricture and the clinical outcomes and predictors of failure after endoscopic retrograde cholangiography with balloon dilation (ERC-D). We enrolled 239 adult patients who underwent LDLT between 2000 and 2006. Sixty-eight patients (28.4%) developed biliary stricture. Twenty-nine patients with anastomotic biliary stricture were treated with ERC-D and stenting. We retrospectively analyzed the risk factors of biliary stricture and the clinical outcomes of ERC-D. The median follow-up period was 31 months. The risk factors of biliary stricture on multiple logistic regression analysis were a graft with multiple bile ducts, a previous history of bile leakage, and hepatic artery stenosis. The overall success rate of ERC-D was 64.5%. On simple logistic regression, the failure of primary ERC-D was associated with late biliary stricture over 24 weeks and more than 8 weeks between a 2-fold increase of serum alkaline phosphatase from the stable level and ERC-D, even though these were not statistically significant on multiple logistic regression. The relapse rate of stricture after successful ERC-D was 30%. The duration of stenting in the recurrence group was shorter than that in the nonrecurrence group (11.8 +/- 5.03 versus 29.0 +/- 11.6 weeks, P = 0.004). ERC-D is effective for the management of anastomotic biliary stricture. However, the failure rate of primary ERC-D may be high in patients with late onset and delayed diagnosis of biliary stricture. The recurrence seems to occur frequently in patients with a short duration of stenting.

Abstract
Biliary complications are still the major source of morbidity for liver transplant recipients. The reported incidence of biliary strictures is 5%-15% after deceased donor liver transplantation and 28%-32% after right-lobe live donor surgery. Presentation is usually within the first year, but the incidence is known to increase with longer follow-up. The anastomotic variant is due to technical factors, whereas the nonanastomotic form is due to immunological and ischemic events, which later may lead to graft loss. Endoscopic management of anastomotic strictures achieves a success rate of 70%-100%; it drops to 50%-75% for nonanastomotic strictures with a higher recurrence rate. Results of endoscopic maneuvers are disappointing for biliary strictures after live donor liver transplantation, and the success rate is 60%-75% for anastomotic strictures and 25%-33% for the nonanastomotic variant. Preventive strategies in the cadaveric donor include the standardization of the type of anastomosis and maintenance of a vascularized ductal stump. In right-lobe live donor livers, donor liver duct harvesting also involves a major risk. The concept of high hilar intrahepatic Glissonian dissection, dissecting the artery and the duct as one unit, use of microsurgical techniques for smaller ducts, use of ductoplasty, and flexibility in the performance of double ductal anastomosis are the critical components of the preventive strategies in the recipient. In the case of live donors, judicious use of intraoperative cholangiograms, minimal dissection of the hilar plate, and perpendicular transection of the duct constitute the underlying principals for obtaining a vascularized duct.

Abstract
BACKGROUND Benign biliary strictures (BBS) are usually managed with plastic stents, whereas placement of uncovered metallic stents has been associated with failure related to mucosal hyperplasia. OBJECTIVE We analyzed the efficacy and safety of temporary placement of a covered self-expanding metal stent (CSEMS) in BBS. DESIGN Patients with BBS received temporary placement of CSEMSs until adequate drainage was achieved; confirmed by resolution of symptoms, normalization of liver function tests, and imaging. SETTING Tertiary-care center with long-standing experience with CSEMSs. PATIENTS Seventy-nine patients with BBS secondary to chronic pancreatitis (32), calculi (24), liver transplant (16), postoperative biliary repair (3), autoimmune pancreatitis (3), and primary sclerosing cholangitis (1). INTERVENTION ERCP with temporary CSEMS placement. Removal of CSEMSs was performed with a snare or a rat-tooth forceps. MAIN OUTCOME MEASUREMENTS End points were efficacy, morbidity, and clinical response. RESULTS CSEMSs were removed from 65 patients. Resolution of the BBS was confirmed in 59 of 65 patients (90%) after a median follow-up of 12 months after removal (range 3-26 months). If patients who were lost to follow-up, developed cancer, or expired were considered failures, then an intent-to-treat global success rate of 59 of 79 (75%) was obtained. Complications associated with placement included 3 post-ERCP pancreatitis (4%), 1 postsphincterotomy bleed (1%), and 2 pain that required CSEMS removal (2%). In 11 patients (14%), the CSEMS migrated. In 1 patient, CSEMS removal was complicated by a bile leak that was successfully managed with plastic stents. LIMITATION Pilot study from a single center. CONCLUSIONS Temporary CSEMS placement in patients with BBS offers a potential alternative to surgery.

Abstract
Biliary complications are significant causes of morbidity and mortality after orthotopic liver transplantation (OLT). The estimated incidence of biliary complications after OLT ranges between 10%-25%, however, these numbers continue to decline due to improvement in surgical techniques. The most common biliary complications are strictures (both anastomotic and non-anastomotic) and bile leaks. Most of these problems can be appropriately managed with endoscopic retrograde cholangiography (ERC). Other complications such as bile duct stones, bile casts, sphincter of Oddi dysfunction, and hemobilia, are less frequent and also can be managed with ERC. This article will review the risk factors, diagnosis, and endoscopic management of the most common biliary complications after OLT.

Abstract
BACKGROUND The study of long-term complications after pancreaticoduodenectomy (PD) for malignant disease has been problematic given the paucity of patients with long-term survival after diagnosis and surgical resection. We therefore studied patients who were surgically treated with a PD for a benign diagnosis to evaluate long-term anastomotic durability. METHODS A retrospective analysis of 122 patients who had PD performed in the interval 1993-2003 inclusive for benign pancreatic diseases was undertaken. Long-term morbidity and mortality (specifically biliary, pancreaticojejunostomy [PJ], and gastrojejunostomy [GJ] strictures) were evaluated. RESULTS Gender was equally represented with 53% female and 47% male. The median age at surgery was 55 years (range 15-81 years). The three most frequent diagnoses were chronic pancreatitis (40%), intraductal papillary mucinous neoplasm (16%), and cystic neoplasms (9%). Median follow-up in the 95 patients alive at last follow-up was 4.1 years (10 days-12.6 years). The 5- and 10-year survival rates were 83% (76, 91%) and 62% (49%, 78%), respectively. The observed survival was significantly lower than the expected survival in an age- and gender-matched U.S. white population, p<0.001 (one-sample log-rank test). The 5- and 10-year cumulative probability of biliary stricture was 8% (2%, 14%) and 13% (4%, 22%), respectively. For pancreatic strictures the 5- and 10-year rates were 5% (0%, 9%) and 5% (0%, 9%), respectively. No GJ strictures were noted. The management of biliary strictures was primarily with dilatation and stent (78%) and less commonly operative intervention (22%). Pancreatic strictures required surgery alone (25%), surgery followed by endoscopic intervention (25%), or endoscopic therapy alone (50%). CONCLUSION Intervention for anastomotic strictures after pancreaticoduodenectomy is uncommon. Biliary strictures can usually be treated nonoperatively with dilation and stent. Our study likely underestimates the incidence of stricture formation. Prospective imaging studies may be warranted for a more accurate assessment of the rate of long-term anastomotic complications.

Abstract
BACKGROUND Biliary anastomotic strictures are a common complication of liver transplantation, occurring in up to 7% of patients at our center. Endoscopic therapy has started to replace surgical biliary reconstruction as the favored means of managing these patients in some centers, although the utility of this approach has never been tested in the setting of a standardized prospective study. METHODS This was a standardized, prospective observational study in the liver transplantation unit, Queen Elizabeth Hospital, Birmingham, United Kingdom. Between June 2000 and August 2006, a total of 791 adults underwent liver transplantation at the Birmingham liver unit and 53 patients were diagnosed with biliary anastomotic strictures. All 53 patients chose to undergo endoscopic therapy and were managed according to the unit's standardized treatment protocol. Data and information from the patient records was collated prospectively, stored in a specific database, and analyzed by intention-to-treat. RESULTS Endoscopic therapy was successful in 69% of patients referred with anastomotic strictures with a median stent free follow up of 18 months. Most patients required a median of 3 endoscopic procedures and two 24F balloon dilatations to adequately treat the stricture. The median continuous indwelling stent period was 11 months. Two patients were re-stented because of jaundice although only one patient had recurrence of the anastomotic stricture (3%). CONCLUSIONS Endoscopic balloon dilatation and stenting is a safe and effective means of treating biliary anastomotic strictures complicating liver transplantation.

Abstract
BACKGROUND Tumour biopsy is usually considered mandatory for patient management by oncologists. Currently percutaneous ablation is used therapeutically for cirrhotic patients with small hepatocellular carcinoma (HCC), not suitable for resection or waiting for liver transplantation. However malignant seeding is a recognized complication of both diagnostic and therapeutic procedures in patients with HCC. Although percutaneous therapy whether with or without biopsy of a suspected HCC nodule may minimize the risk of seeding, this has not been confirmed. AIM To evaluate the risk of seeding, defined as new neoplastic disease occurring outside the liver capsule, either in the subcutaneous tissue or peritoneal cavity following needle biopsy and/or local ablation therapy (LAT). METHODS A literature search resulted in 179 events in 99 articles between January 1983 and February 2007: 66 seedings followed liver biopsy, 26 percutaneous ethanol injection (PEI), 1 microwave, 22 radiofrequency ablation (RFA), and 64 after combined biopsy and percutaneous treatment (5 microwave; 33 PEI; 26 RFA). RESULTS In 41 papers specifying the total number of patients biopsied and/or treated, the median risk of seeding was 2.29% (range 0-11%) for biopsy group; 1.4% (1.15-1.85%) for PEI when used with biopsy and 0.61% (0-5.56%) for RFA without biopsy, 0.95% (0-12.5%) for RFA with biopsy and 0.72% (0-10%) for liver nodules (including non-HCC nodules) biopsied and ablated. CONCLUSION Risk of seeding with HCC is substantial and appears greater with using diagnostic biopsy alone compared to therapeutic percutaneous procedures. This risk is particularly relevant for patients being considered for liver transplantation.

Abstract
Biliary complications are a major cause of morbidity following orthotopic liver transplantation with an overall incidence between 11% and 25%. The most common complications are biliary leaks, strictures, and stones. These complications have an impact on graft survival, length of hospital stay, recovery, and overall cost of care. Therefore, knowledge of these complications and their management is important to the practicing gastroenterologist. Historically, biliary complications after liver transplantation have been managed surgically. However, with the growth of therapeutic endoscopic and percutaneous radiologic methods, most of these complications can now be managed less invasively. This article focuses on the incidence, timing, mechanism, and endoscopic management of biliary leak, strictures, stones, sludge, casts, and sphincter of Oddi dysfunction following liver transplantation.
