A single center cohort study. Pediatr Transplant 2021; 25:e14014.

Abstract
BACKGROUND The technique of « en bloc» liver and small bowel transplantation (L-BT) spares a biliary anastomosis, but does not protect against biliary complications. We analyze biliary and duodenal complications (BDC) in our pediatric series. METHODS Between 1994 and 2020, 54 L-BT were performed in 53 children. The procurement technique included in situ vascular dissection and pancreatic reduction to the head until 2009 (group A). Thereafter, the whole pancreas was recovered (group B). RESULTS Nine BDCs occurred in 8/53 (15%) patients (7 in group A and 1 in group B): leak of the donor's duodenal stump (2), stenosis of the extra-pancreatic bile duct (5), and intra-pancreatic bile duct stenosis (2). Median delay for diagnosis of stricture was 8 months (4-168). Interventional radiology was successful in one child only, the others required reoperations. Two patients died, of biliary cirrhosis or cholangitis, 15-month and 12-year post-L-BT. One was listed and liver re-transplanted 13 years post-L-BT. At last follow-up, two patients only had normal liver tests and ultrasound. CONCLUSION BDC after L-BT can cause severe morbidities. Pancreatic reduction might increase this risk. Early surgical complications or chronic pancreatic rejection might be co-factors. Early diagnosis and treatment are key to the long-term prognosis.

Abstract
BACKGROUND Bilio-enteric diversion is the current surgical standard in patients after deceased donor liver transplantation (DDLT) with a biliary anastomotic stricture failing interventional treatment and requiring surgical repair. In contrast to this routine, the aim of this study was to show the feasibility and safety of a duct-to-duct biliary reconstruction. PATIENTS Between 2012 and 2019, we performed a total of 308 DDLT in 292 adult patients. The overall biliary complication rate was 20.5%. Patients with non-anastomotic or combined strictures were excluded from this analysis. Out of 273 patients after a primary duct-to-duct reconstruction, 20 (7.3%) developed late isolated AS. Seven of these patients failed interventional biliary treatment and required a surgical repair. RESULTS Duct-to-duct reconstruction was feasible and successful in all patients. Liver function tests fully normalized and no patient required any form of biliary intervention after surgery. One patient with intraoperative cholangiosepsis was ICU bound for 5 days, and another patient with a subhepatic abscess required percutaneous drainage. There was no perioperative death. The median length of hospital stay was 8 (5-17) days. The median time of follow-up after relaparotomy was 1593 (434-2495) days. CONCLUSION Duct-to-duct reconstruction is a feasible and safe option in selected patients requiring surgical repair for isolated AS after DDLT. This approach preserves the biliary anatomy and avoids the potential side effects of a bilio-enteric diversion.

Abstract
Biodegradable polymers are promising materials for use in medical applications such as stents. Their properties are comparable to commercially available resistant metal and polymeric stents, which have several major problems, such as stent migration and stent clogging due to microbial biofilm. Consequently, conventional stents have to be removed operatively from the patient's body, which presents a number of complications and can also endanger the patient's life. Biodegradable stents disintegrate into basic substances that decompose in the human body, and no surgery is required. This review focuses on the specific use of stents in the human body, the problems of microbial biofilm, and possibilities of preventing microbial growth by modifying polymers with antimicrobial agents.

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

Long-term Outcome of Endoscopic and Percutaneous Transhepatic Approaches for Biliary Complications in Liver Transplant Recipients. Transplant Direct 2019; 5:e432.

Abstract
Background Biliary complications occur in 6% to 34% of liver transplant recipients, for which endoscopic retrograde cholangiopancreatography has become widely accepted as the first-line therapy. We evaluated long-term outcome of biliary complications in patients liver transplanted between 2004 and 2014 at Karolinska University Hospital, Stockholm. Methods Data were retrospectively collected, radiological images were analyzed for type of biliary complication, and graft and patient survivals were calculated. Results In 110 (18.5%) of 596 transplantations, there were a total of 153 cases of biliary complications: 68 (44.4%) anastomotic strictures, 43 (28.1%) nonanastomotic strictures, 24 (15.7%) bile leaks, 11 (7.2%) cases of stone- and/or sludge-related problems, and 7 (4.6%) cases of mixed biliary complications. Treatment success rates for each complication were 90%, 73%, 100%, 82% and 80%, respectively. When the endoscopic approach was unsatisfactory or failed, percutaneous transhepatic cholangiography or a combination of treatments was often successful (in 18 of 24 cases). No procedure-related mortality was observed. Procedure-related complications were reported in 7.7% of endoscopic retrograde cholangiopancreatography and 3.8% of percutaneous transhepatic cholangiography procedures. Patient survival rates, 1, 3, 5, and 10 years posttransplant in patients with biliary complications were 92.7%, 80%, 74.7%, and 54.1%, respectively, compared with 92%, 86.6%, 83.7%, and 72.8% in patients free from biliary complications (P < 0.01). Similarly, long-term graft survival was lower in the group experiencing biliary complications (P < 0.0001). Conclusions Endoscopic and percutaneous approaches for treating biliary complications are safe and efficient and should be considered complementing techniques. Despite a high treatment success rate of biliary complications, their occurrence still has a significant negative impact on patient and graft long-term survivals.

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

Peripheral portal vein-oriented non-dilated bile duct puncture for percutaneous transhepatic biliary drainage. World J Gastroenterol 2015; 21:12628-12634. [PMID: 26640339 PMCID: PMC4658617 DOI: 10.3748/wjg.v21.i44.12628] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2015] [Revised: 07/31/2015] [Accepted: 09/30/2015] [Indexed: 02/06/2023] Open
Abstract
AIM: To evaluate the efficacy of peripheral portal vein (PV)-oriented non-dilated bile duct (BD) puncture for percutaneous transhepatic biliary drainage (PTBD).
METHODS: Thirty-five patients with non-dilated BDs underwent PTBD for the management of various biliary disorders, including benign bilioenteric anastomotic stricture (n = 24), BD stricture (n = 5) associated with iatrogenic BD injury, and postoperative biliary leakage (n = 6). Under ultrasonographic guidance, percutaneous transhepatic puncture using a 21-G needle was performed along the running course of the peripheral targeted non-dilated BD (preferably B6 for right-sided approach, and B3 for left-sided approach) or along the accompanying PV when the BD was not well visualized. This technique could provide an appropriate insertion angle of less than 30° between the puncture needle and BD running course. The puncture needle was then advanced slightly beyond the accompanying PV. The needle tip was moved slightly backward while injecting a small amount of contrast agent to obtain the BD image, followed by insertion of a 0.018-inch guide wire (GW). A drainage catheter was then placed using a two-step GW method.
RESULTS: PTBD was successful in 33 (94.3%) of the 35 patients with non-dilated intrahepatic BDs. A right-sided approach was performed in 25 cases, while a left-sided approach was performed in 10 cases. In 31 patients, the first PTBD attempt proved successful. Four cases required a second attempt a few days later to place a drainage catheter. PTBD was successful in two cases, but the second attempt also failed in the other two cases, probably due to poor breath-holding ability. Although most patients (n = 26) had been experiencing cholangitis with fever (including septic condition in 8 cases) before PTBD, only 5 (14.3%) patients encountered PTBD procedure-related complications, such as transient hemobilia and cholangitis. No major complications such as bilioarterial fistula or portal thrombosis were observed. There was no mortality in our series.
CONCLUSION: Peripheral PV-oriented BD puncture for PTBD in patients with non-dilated BDs is a safe and effective procedure for BD stricture and postoperative bile leakage.

Abstract
A hepatitis B virus carrier suffering from acute flare of chronic hepatitis B infection underwent deceased-donor liver transplantation. He was put on the immunosuppressive agent tacrolimus. On routine follow-up, he was found to have abnormal liver function. Computed tomography scan of the abdomen did not show any dilatation of the biliary system. Liver biopsy showed scattered microabscesses, and a microgranuloma was detected. Endoscopic retrograde cholangiography was performed and a biliary anastomotic stricture (BAS) was noted. In addition, the Chinese liver fluke, Clonorchis sinensis, was discovered. Balloon dilatation and stenting were performed. The patient was given a course of praziquantel. His liver function improved and normalized. We present the case of a liver transplant recipient with cholangitis caused by C. sinensis infestation and infection and biliary obstruction resulting from BAS.

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

Abstract
AIM: To investigate the diagnostic performance of multi-detector computed tomography (MDCT) in detecting biliary complications after orthotopic liver transplantation (OLT).
METHODS: Eighty-three consecutive OLT recipients, who presented with clinical or biochemical signs of biliary complications, underwent MDCT examination. Two experienced radiologists assessed MDCT images in consensus to determine biliary complications. Final confirmation was based on percutaneous transhepatic cholangiography or endoscopic retrograde cholangiography in 58 patients, surgery in four patients, liver biopsy in 10, and clinical and sonography follow-up in 11 patients.
RESULTS: Biliary complications were eventually confirmed in 62 of 83 patients (74.7%), including anastomotic biliary strictures in 32, nonanastomotic biliary strictures in 21, biliary stones in nine (5 with biliary strictures), anastomotic bile leak in five, and biloma in six (all with nonanastomotic strictures, and 2 with biligenic hepatic abscess). Twenty-one patients had no detection of biliary complications. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of MDCT for detecting biliary strictures were 90.6%, 86.7%, 89.2%, 92.3% and 83.9%, respectively. For detecting biliary stones, anastomotic bile leak and biloma, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of MDCT were all 100%.
CONCLUSION: MDCT is a useful screening tool for detecting biliary complications after OLT.

Abstract
BACKGROUND Treatment or prevention of a benign biliary tree stricture is an unresolved problem. A novel self-expandable biodegradable polydioxanon biliary stent in a porcine model was studied. MATERIALS AND METHODS This new stent was used in 23 pigs. Feasibility and safety of surgical stenting, time of biodegradation, and histologic reaction in 2, 8, 13, and 20 wk of a follow-up were studied. All stents were inserted into a common bile duct through a duodenal papilla following small dilatation. After surgical evaluation of abdominal cavities, the pigs were sacrificed to remove common bile ducts with the stents. All bile ducts were assessed by macroscopic and histopathologic examination. RESULTS Self-expansion was correct in all cases. Neither bile duct obstruction nor postsurgical complications were observed. Macroscopic evaluation indicated lightening of the stent color in 2 wk, a partial disintegration in 8 wk, and a complete absorption in 13 and 20 wk. Histologic evaluation in general substantiated a mild-to-moderate inflammatory reaction in the lamina propria during the whole follow up and had no clinical consequences. No cholangitis, necrosis, abscess, or excessive fibroplasia was found in a hepatoduodenal ligament. CONCLUSIONS Our results suggest that polydioxanon biodegradable self-expanding stents seem to be useful for biliary system implantation, offer a good biocompatibility, and completely degrade within 13 wk.

Abstract
OBJECTIVE AND BACKGROUND Bile leakage is a serious postoperative complication and percutaneous transhepatic biliary drainage (PTBD) may be an option when endoscopic treatment is not feasible. In this retrospective study, we established technical and clinical success rates as well as the complication rates of PTBD in a large group of patients with postoperative bile leakage. METHODS Data on all patients with nondilated intrahepatic bile ducts who underwent a PTBD procedure for the treatment of bile leakage between January 2000 and August 2012 were retrospectively assessed. Data included type of surgery, site of bile leak, previous attempts of bile leak repair, interval between surgery and PTBD placement. Outcome measures were the technical and clinical success rates, the procedure-related complications, and mortality rate. RESULTS A total of 63 patients were identified; PTBD placement was technically successful in 90.5% (57/63) after one to three attempts. The clinical success rate was 69.8% (44/63). Four major complications were documented (4/63; 6.3%): liver laceration, pneumothorax, pleural empyema, and prolonged hemobilia. One minor complication involved pain. CONCLUSIONS PTBD is an effective treatment with low complication rates for the management of postsurgical bile leaks in patients with nondilated bile ducts.

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
Due to a vulnerable blood supply of the bile ducts, biliary complications are a major source of morbidity after liver transplantation (LT). Manifestation is either seen at the anastomotic region or at multiple locations of the donor biliary system, termed as nonanastomotic biliary strictures. Major risk factors include old donor age, marginal grafts and prolonged ischemia time. Moreover, partial LT or living donor liver transplantation (LDLT) and donation after cardiac death (DCD) bear a markedly higher risk of biliary complications. Especially accumulation of several risk factors is critical and should be avoided. Prophylaxis is still a major issue; however no gold standard is established so far, since many risk factors cannot be influenced directly. The diagnostic workup is mostly started with noninvasive imaging studies namely MRI and MRCP, but direct cholangiography still remains the gold standard. Especially nonanastomotic strictures require a multidisciplinary treatment approach. The primary management of anastomotic strictures is mainly interventional. However, surgical revision is finally indicated in a significant number of cases. Using adequate treatment algorithms, a very high success rate can be achieved in anastomotic complications, but in nonanastomotic strictures a relevant number of graft failures are still inevitable.

Abstract
OBJECTIVE The purpose of this study is to compare technical success and complications of percutaneous transhepatic cholangiography (PTC) and percutaneous transhepatic biliary drainage (PTBD) between patients with and without transplanted liver. MATERIALS AND METHODS Between 2007 and 2011, 89 PTCs, including 34 PTBDs, in 87 patients with transplanted liver were attempted, and 131 PTCs, including 118 PTBDs, in 126 patients without transplanted liver were attempted. Technical success, diameters of the bile ducts, fluoroscopy time, and complications were statistically compared between the two groups. RESULTS The technical success rate of PTC for transplanted liver was significantly lower than that for nontransplanted liver (88.8% vs 98.5%; p = 0.004). Consequently, the technical success rate of PTBD for transplanted liver was also significantly lower than that for nontransplanted liver (75.0% vs 95.8%; p < 0.001). The average diameters of the first branches and second branches of the bile ducts of transplanted liver were significantly smaller than those of nontransplanted liver (5.8 ± 3.4 mm vs 8.7 ± 3.9 mm for the first branches [p < 0.001]; and 3.7 ± 1.7 mm vs 5.8 ± 2.4 mm for the second branches [p < 0.001]). No significant difference of fluoroscopy time of unilateral successful PTBD was observed (21.8 ± 11.7 vs 19.3 ± 12.9 min; p = 0.372), and no significant difference of overall complication rates was observed (8.0% vs 8.7%; p = 1.000) between transplanted and nontransplanted liver. CONCLUSION The technical success rates of PTC and PTBD for transplanted liver are slightly lower than those for nontransplanted liver because the bile ducts are smaller. There is no significant difference in complication rate.

Abstract
OBJECTIVES To summarize the pathotyping and clinical manifestations of biliary cast syndrome in patients after an orthotopic liver transplant. MATERIALS AND METHODS The clinical manifestations, auxiliary examination, therapeutic regimen, and clinical efficacy of 103 biliary cast syndrome patients who underwent an orthotopic liver transplant were retrospectively analyzed. Patients were divided into 6 groups from type 1 to type 6, according to the injury level of the biliary duct epithelium. RESULTS Many biliary cast syndrome patients showed symptoms including jaundice, dark urine, argillaceous stool, itchy skin, and fever. Serum levels of alanine aminotransferase, γ-glutamyl transpeptidase, alkaline phosphatase, and total bilirubin were increased. In addition, total white cell counts in peripheral blood also were increased. T-tube cholangiography showed filling defects of various amounts. Optical fiber choledochoscope examination revealed that the biliary tract was filled with solid substances, and necrosis of the biliary tract epithelium was observed in some biliary cast syndrome patients. From type 1 to type 6 biliary cast syndrome patients, the probability of clinical symptoms and biliary tract stricture gradually increased, the time needed for supporting gradually prolonged after removal of the biliary cast, and T-tube cholangiography showed that the filling defects gradually expanded. CONCLUSIONS Clinical manifestations and cholangiography presentations mainly depend on pathotyping.

Abstract
PURPOSE The aim of this study was to evaluate our experience with percutaneous treatment of biliary strictures after orthotopic liver transplantation in adult patients without the endoscopic access possibility and to evaluate the technical outcomes and long-term clinical results of this treatment. MATERIALS AND METHODS Thirty percutaneous procedures were performed in adult liver transplant recipients (13 men, 17 women, mean age 46.4 years) in our institution between 1996 and 2010. Patients were treated with balloon dilatation and biliary duct drainage due to anastomotic stenosis (n = 20), nonanastomotic stenosis (n = 7), or due to stenosis caused by lymphoproliferation (n = 3). The percutaneous procedure was the first line of treatment due to hepaticojejunoanastomosis (n = 18) or after unsuccessful endoscopic therapy (n = 12). RESULTS Technical success was achieved in 27 patients (90%). The remaining three patients only achieved external drainage with subsequent surgery. There were two complications (6.3%). Long-term clinical success, defined as the absence of clinical, laboratory, or sonographic signs of stricture recurrence was achieved in 22 patients (73.3%) for a mean follow-up of 5.8 years. CONCLUSION Percutaneous treatment--balloon dilatation and biliary duct drainage--is a first-line option to manage biliary duct strictures in liver recipient, when endoscopic treatment is not possible or unsuccessful. It has a high technical success rate and low complication rate with favorable long-term results.

Abstract
Benign biliary stenosis can have various causes and requires differentiation from disorders caused by malignant disease. Treatment of benign stenosis is often difficult and includes treatment modalities such as endoscopic, percutaneous or surgical interventions. Exact knowledge of the etiology and localization of the stenosis is essential when selecting the appropriate method of treatment. Here we present the case of a 71-year-old patient admitted to our hospital with cholangitis 13 years after undergoing radiotherapy of the renal bed due to hypernephroma of the right kidney. The patient was diagnosed with common bile duct stenosis due to the secondary effects of radiation, which is rarely reported in the literature. Our case covers a total treatment period of 15 years, enabling us to also discuss a viable sequence of treatment modalities in the treatment of benign bile duct stenosis.

Abstract
Anastomotic strictures (ASs) of the biliary duct after liver transplantation (LT) are primarily managed with endoscopic retrograde cholangiopancreatography (ERCP), but in some cases, this fails because of difficulties in passing the strictures. The aim of this case-control study was to examine specific risk factors for initial ERCP failure and the outcomes of percutaneous transhepatic cholangiography (PTC) as a second-line approach in LT recipients with ASs. Between January 2002 and December 2010, we identified LT recipients with ASs who experienced initial ERCP failure (which was defined as the inability to traverse the AS with guidewires in 2 or more consecutive procedures). A period-matched control group (ratio = 1:2) with ASs and initial ERCP success was analyzed. Preoperative, intraoperative, postoperative, and endoscopic variables were evaluated as risk factors. The outcomes of PTC and the need for hepaticojejunostomy (HJ) or retransplantation were evaluated. Seventeen cases who experienced initial ERCP failure were compared with 34 controls. The median times from LT to ERCP were similar (8.7 months for cases and 8.6 months for controls, P = not significant). A multivariate analysis revealed that previous bile leaks [odds ratio (OR) = 6.07, 95% confidence interval (CI) = 1.0-36.5] and more than 4 U of intraoperatively transfused red blood cells (OR = 11.51, 95% CI = 1.9-71.2) were independent risk factors for failure. PTC was an effective second-line treatment in only 3 of 12 cases (25%). The need for HJ was more frequent for the cases (13/17 or 76.5%) versus the controls (7/34 or 20.6%, P < 0.001). One patient in each group underwent retransplantation (P = not significant). In conclusion, previous bile leaks and high packed red blood cell transfusion requirements during surgery are risk factors for initial ERCP failure in LT recipients with ASs. A high proportion of these patients will need surgery as their final therapy.

Abstract
BACKGROUND Complications of the biliary tract after liver transplantation are successfully managed with ERCP; however, the incidence and risk factors for post-ERCP complications remain unknown. OBJECTIVE To examine the incidence, risk factors, and short-term outcome of post-ERCP complications in liver transplant (LT) recipients. DESIGN Retrospective evaluation of all ERCPs performed in LT recipients at our institution during a 7-year, 4-month period. SETTING Tertiary referral center. PATIENTS A total of 243 ERCPs performed in 121 LT recipients with duct-to-duct anastomosis. MAIN OUTCOME MEASUREMENTS Incidence of post-ERCP complications. Predictive factors were determined by univariate and multivariate analyses. RESULTS Overall complications occurred in 22 procedures (9%) (13 mild, 9 moderate): pancreatitis in 9 patients (3.7%), cholangitis in 8 patients (3.3%), postsphincterotomy bleeding in 4 patients (1.6%), and subcapsular hematoma in 1 patient (0.4%). The mean hospitalization for post-ERCP complications was 4.8 days (range 2-11 days). Logistic regression identified mammalian target of rapamycin inhibitors (odds ratio [OR], 4.65; 95% CI, 1.01-21.81; P = .049), serum creatinine level greater than 2 mg/dL (OR, 4.17; 95% CI, 1.07-16.26; P = .04), biliary sphincterotomy (OR, 3.03; 95% CI, 1.07-8.53; P = .037), and more than 2 pancreatic duct contrast injections (OR, 2.95; 95% CI, 1.10-7.91; P = .032) as independent risk factors for post-ERCP complications, whereas steroid therapy (OR, 0.23; 95% CI, 0.08-0.63; P = .004) was an independent protective factor. LIMITATIONS Single-center retrospective study. CONCLUSIONS The rate of complications after ERCP in LT recipients seems to be similar to that of non-LT recipients. Complications in this analysis were more common in LT recipients receiving mammalian target of rapamycin inhibitors and those with renal failure, biliary sphincterotomy, and more than 2 pancreatic duct injections, whereas they were less common in those patients on steroid therapy.

Abstract
Biliary plastic stenting plays a key role in the endoscopic management of benign biliary diseases. Complications following surgery of the biliary tract and liver transplantation are amenable to endoscopic treatment by plastic stenting. Insertion of an increasing number of plastic stents is currently the method of choice to treat postoperative biliary strictures. Benign biliary strictures secondary to chronic pancreatitis or primary sclerosing cholangitis may benefit from plastic stenting in select cases. There is a role for plastic stent placement in nonoperative candidates with acute cholecystitis and in patients with irretrievable bile duct stones.

Abstract
This is the Fourth Annual Meeting of the Society for Gastrointestinal Intervention, a multi-disciplinary group of practitioners committed to a minimally invasive approach to both the diagnosis and treatment of digestive disorders. The key concepts are minimally invasive and multi-disciplinary which can be construed as practicing in parallel with occasional lines of procedural and clinical interaction or inter-disciplinary in which patients are acutely cared for by a team, with treatments tailored to the patient and not the discipline that touches the patient first. In reality, many of us exist in both worlds. Most universities and large clinics are structured in departments along traditional training lines. As such, Interventional Radiology is housed in the Radiology Department, Laparoscopic Surgery (and potentially NOTES), as a component of the General Surgery Division, and Therapeutic Endoscopy usually resides within a gastroenterology structural framework. These divisions have historically been kept separate by multiple forces: salaries and budgets usually reside in a larger division. As a group, the amount of practice devoted to GI disorders is variable (for instance, minimally invasive surgeons may approach the adrenal glands or lung lesions in some institutions and interventional radiologists often sample tissue in multiple areas outside the GI tract, and by virtue of access to the vascular tree, can stent, embolize, or TPA almost any area of the body), as well as inherent differences in our individual abilities to access organs. I have already mentioned that angiographic capabilities allow the interventional radiologist access to virtually every GI organ and those capabilities allow therapeutic options for bleeding, tumor embolization, stenting of stenotic lesions, and formation of intravascular shunts. As such, there is very limited interdisciplinary competition here although capsule endoscopy as well as double and single balloon enteroscopy have improved the endoscopist's diagnostic and potential therapeutic reach. However, many of these diagnostic triumphs for obscure or massive GI bleed are simply to tattoo lesions that require surgical removal by laparoscopic or traditional surgery. Cooperation. However, there are potential competitive areas in the treatment of GI vascular lesions also. Whereas endoscopic band ligation has supplanted EVS, splenic devascularization, and most shunting procedures for patients with esophageal varices, endoscopic techniques have had less long-term success with glue injection for gastric varices. Multiple randomized, prospective trials have suggested therapeutic primacy of TIPS with embolization of recalcitrant vessels as an option or back-up. Despite this, therapeutic endoscopists have learned valuable lesions from our IR colleagues and studies are underway using endoscopically injected coils in addition to cyanoacrylate in an attempt to improve acute and long-term bleeding control. Nor is there any major competition in the treatment of primary or metastatic liver tumors by chemoembolization, RF current, or other thermal modalities, although selected patients with single lesions or multiple lesions isolated to a single lobe may be better handled surgically if there is curative intent. Finally, there is little IR, and progressively less, surgical competition for the treatment of high-grade dysplasia or superficial malignancies in the setting of Barrett's esophagus which are adequately treated in most patients by mucosectomy, RF ablation, or cryotherapy but require direct mucosal visualization to direct this therapy. The same has proven true for many years for colorectal polyps, superficial gastric cancers, and ampullary adenomas that had historically all been treated with major surgical resections. Still, there are many patients with advanced lesions who are good operative candidates who should be approached with conventional or minimally invasive surgery with the intent of operative cure. Cooperative, not competitive. The potential for competition between disciplines comes in mundane situations and clinical settings that have historically been "owned" by a single discipline. On the one hand, placement of PEGS and PEJs, initially done endoscopically, can be done with equal facility and occasional failure, by endoscopists and interventional radiologists, reserving failed attempts for minimally invasive surgery. What resources are utilized with these three methods? Are there advantages to defining the mucosa of the gut lumen in all, or even a subset of patients? By way of contrast, acute cholecystectomy tubes in high surgical risk patients have usually been the domain of the radiologist, although I described transcystic duct gallbladder decompression endoscopically 2½ decades ago. With the advent of new devices delivered under EUS control, the gallbladder will now be readily accessible endoscopically. What does this mean both for the acutely ill patient without a window to approach their gallbladder radiologically? Will this play a bit part and a cooperative technique to expand our therapeutic armamentarium or will it become competitive therapeutically not only for IR but for minimally invasive surgeons? The same may be said for EUS's ability to inject genes, caustics, or chemo-therapeutic agents into organs adjacent to the lumen. What is the role of TNFerade injection into unresectable pancreatic cancers and the role of absolute alcohol or Taxitol to treat cystic neoplasms of the pancreas? The real issue of competition or cooperation between the disciplines comes when treating patients with unresectable and obstructing GI neoplasms, from my perspective. The latter may occur almost anywhere in the GI tract but, of course, are more commonly noted proximally (esophagus, stomach, duodenum) and distally (left colon) as well as proximal and distal biliary obstructions. Recognizing that the occasional mid-small bowel and many proximal colon lesions are better handled with an endoscopic approach because of loss of vector force and difficulty pushing a catheter through large diameter, acutely angulated lumens, all others are fair game from my perspective. To my knowledge, although there are studies demonstrating the superiority of SEMS over open or laparoscopic bypass for malignant gastric outlet obstruction insofar as return of gut function, hospitalization time, and resource utilization, there are no studies demonstrating the superiority of one discipline or another in the placement of SEMS. Nor have cost data emerged suggesting the superiority of one technique over another from a cost standpoint. Unless or until we have such studies, this suggests to me that institutional interest and expertise should play a major role in how these unfortunate patients have continuity of their GI tract re-established. The situation is a bit more complex in pancreaticobiliary malignancy. There are 2 prospective randomized trials (level 1 evidence) that suggest that patients with proximal strictures (Bismuth II-IV) in conjunction with bile duct and gallbladder cancer, respectively, may be more successfully stented percutaneously and certainly it is easier to deliver brachytherapy or PDT under protocol to these patients who have indwelling external drains. In contrast, there are no data, positive or negative, to suggest that PTBD is a preferable treatment for distal biliary malignant obstruction, and in most parts of the world, the endoscopic approach has supplanted the percutaneous one just as metal stents have replaced plastic prostheses to preclude recurrent bouts of stent dysfunction and need for additional ERCP. The question posed at the beginning of this syllabus contribution: Are we competitive or cooperative? The answer is obviously both but, hopefully, our choice of treatment should depend less on who touches the patient first and more on skill sets within an institution and what is the best treatment for this particular individual. The importance of the SGI is technical and informational cross-fertilization. If your university or clinic will not allow blurring of training barriers to put therapeutic endoscopists, minimally invasive surgeons, and interventional radiologists together as a department or institute, you can nevertheless work together as a team in the best interest of your patients.
