Abstract: Objective?To explore the application of plastic pancreatic stents and/or nasal biliary drainage for choledocholithiasis patients having DSBC during Endoscopic Retrograde Cholangiopancreatography (ERCP).?Methods?Retrospective analysis on clinical data of 57 ERCP cases aiming at choledocholithiasis patients having DSBC from January 2010 to December 2015 has been carried out. According to the guide wire cannulation in an operation, patients are divided into three groups, i.e. plastic pancreatic stents group, nasal biliary drainage group, and plastic pancreatic stents + nasal biliary drainage group, so as to observe the success rate of operation and the occurrence rate of postoperative complications, such as pancreatitis or hyperamylasemia, as well as to compare the differences between the three groups.?Results?Out of the 57 patients receiving ERCP, 13 patients are in the plastic pancreatic stents group, with two successful operations (15.4%), one case of hyperamylasemia (7.7%), two cases of postoperative pancreatitis (15.4%), one case of fever (7.7%) and one case of hemorrhage (7.7%); 20 patients are in the nasal biliary drainage group, with 20 successful operations (100.0%), no occurrence of hyperamylasemia or postoperative pancreatitis or other complications including hemorrhage and fever; 24 patients are in the plastic pancreatic stents + nasal biliary drainage group, with 19 ERCP operations succeeded at the first attempt (79.2%) and 5 ERCP operations succeeded at the second try (20.8%), as well as 4 cases of hyperamylasemia (16.7%), 2 cases of hemorrhage (8.3%) , no occurrence of fever cases and postoperative pancreatitis. In comparison between the three groups, the occurrence of postoperative pancreatitis and successful rate of operation show a significant difference.?Conclusion?By adopting plastic pancreatic stents and/or nasal biliary drainage for patients having a difficult selective biliary cannulation during ERCP, the success rate of operation can be improved, and the occurrence of pancreatitis can also be reduced.

Abstract: Background and objectives: plastic biliary stents are often used after an ERCP session without complete common bile duct stones (CBDS) extraction. Sometimes, the volume of biliary drainage with these stents may be insufficient. We present our experience with the use of fully covered self-expanding metal stents (FCSEMS) in the setting of incomplete CBDS extraction. Patients and methods: after an ERCP session with difficult CBDS not completely removed, biliary FCSEMS (Wallflex) were inserted in some patients when it was deemed that biliary sphincterotomy and a single plastic stent would not provide an adequate drainage. Results: a retrospective study was performed. Biliary FCSEMS were inserted in 29 patients, mean age 81 years. CBDS could not be extracted through a biliary sphincterotomy due to its large size (n = 18) or because of the presence of inflammatory distal strictures (n = 11). The greatest biliary drainage with shortest ERCP time was considered mandatory due to clinical instability of patients and/or poor tolerance to conscious sedation administered by the endoscopist. Successful biliary drainage was obtained in all cases. FCSEMS were removed after a median of 199.5 days in 16 patients with a complete CBDS extraction in 15 (93.7%). FCSEMS were not removed in the remaining 13 patients due to their clinical condition, and a wait-and-see strategy was undertaken. Conclusions: in selected cases, utilization of removable FCSEMS can be a good option for a quick and adequate biliary drainage in the setting of difficult CBDS. Because of the higher cost of these stents its use needs to be individualized. Introducción y objetivos: las prótesis biliares plásticas suelen emplearse tras una sesión de CPRE sin extracción completa de coledocolitiasis. En ocasiones, el calibre de drenaje con estas prótesis puede ser insuficiente. Presentamos nuestra experiencia en la utilización de prótesis metálicas autoexpandibles totalmente recubiertas (PMATR) en coledocolitiasis no extraídas. Pacientes y métodos: se insertó una PMATR (Wallflex biliar) en algunos pacientes con coledocolitiasis difíciles no extraídas tras una sesión de CPRE cuando se consideró que la esfinterotomía biliar y una prótesis plástica no aportaban un calibre de drenaje adecuado. Resultados: estudio retrospectivo en el que se utilizó una PMATR en 29 pacientes, edad media 81 a os. Las coledocolitiasis no pudieron extraerse por la esfinterotomía biliar debido a su gran tama o (n = 18) o por la presencia de estenosis distal inflamatoria (n = 11). Se consideró que era preciso el mayor drenaje biliar con

Abstract: Studies have shown that SEMS remain patient longer with fewer associated complications compared with conventional plastic strents. Zilver stent , a nitinol zig-zag mash SEMS has a special advantage, having a thin introducer diameter of 7 Fr with a fully deployed span of 10mm. For a 48- year-old woman presented with obstructive jaundice and a diagnosis of unresectable pancreatic carcinoma with consequent stenosis of common bile duct (CBD), infiltration of local blood vessels and life expectancy longer than six months, it was decided that an endoscopic palliative drainage procedure should be performed. The technique of transendoscopic plastic to metal stent exchange is described, using a diagnostic duodenoscope. The patient lived 7 months after implementation of Zilver stent and died anicteric due to progression of a primary disease. The transendoscopic plastic to metal stent exchange is feasible palliative method which requires a basic endoscopic equipment and experienced staff and therefore is applicable in developing countries as well.

Abstract: Background and Aims: Palliation therapy is the only available therapeutic method for most patients with tumor-induced obstructive jaundice. Metallic stents are now performed percutaneously as an alternative route to the endoscopic approach. It is widely accepted because of its safety, good patency rate, and minimal invasiveness. This study was designed to evaluate the long-term results of metallic self-expandable stent insertion in patients with malignant stenosis of the biliary tree.Methods: It is a longitudinal study of patients with percutaneously biliary stenting from September 2005 to March 2009. The patients had unresectable malignant biliary obstruction with unsuccessful endoscopic stenting and access. Percutaneous transhepatic cholangiogram performed after adequate local anesthesia, under sonographic or fluoroscopic guidance. Stenting or balloon dilation was performed through the hydrophilic guide wire. Among 50 patients, 45 stents were placed in biliary tree stenosis sites. Patients' follow-up was during the first, second, third, and then the sixth month after insertion of biliary stents. Stent patency was considered successful in our patients, when there were no lab results or sonographic appearance of biliary tree obstruction.Results: 10(20%) patients' stent placement treatment failed because of unsuccessful technical procedure. The stenosis of biliary tract was complete and passage of guide wire was not possible through the tumor growth. 6 (15 %) patients with successful stent placements died within one month (mean, 22 days). Total serum bilirubin resolved to below 1.5 mg/dl within 30 days for 36 (90%) patients with successful stent placements. Early complications not leading to death occurred in 28% of cases. The mean survival time for all patients who underwent stent placement was 140 days (16-420days). The mean patency rate for all stents was 147 days.Conclusions: Percutaneous biliary stenting is a safe procedure with few technical complications and a high success rate of palliation for patients with malignant biliary jaundice. Early complications are mostly managed conservatively and death is mainly due to systemic effects of the malignant disease.

Abstract: standard surgical techniques offer a good chance of cure forthe majority of patients affected by extrahepatic benign biliarystricture. nevertheless, operative repair has a long-termrecurrence rate of stricture in 10% to 30% of patients. advancesin endoscopic procedures have provided alternative options ofrelieving biliary obstructions, but prolonged length of treatmentand rehospitalization have to be considered if endoscopy isperformed. malignant stenoses are an important factor determining cholangitis, jaundice and pain and it's each systemic consequences. the endoscopic approach intends to create a deviation of bile juice to duodenum by means of metal or plastic stents aiming a safe palliation. the purpose of this review is to show to the readers effectiveness of endoscopic treatments of benign and malignat stenosis of the bile duct and pancreatic.

Abstract: This report describes a method for percutaneous transhepatic biliary stenting with a BLAKE Silicone Drain, and discusses the usefulness of placement of the drain connected to a J-VAC Suction Reservoir for the treatment of stenotic hepaticojejunostomy. Percutaneous transhepatic biliary drainage was performed under ultrasonographic guidance in a patient with stenotic hepaticojejunostomy after hepatectomy for hepatic hilum malignancy. The technique used was as follows. After dilatation of the drainage root, an 11-Fr tube with several side holes was passed through the stenosis of the hepaticojejunostomy. A 10-Fr BLAKE Silicone Drain is flexible, which precludes one-step insertion. One week after insertion of the 11-Fr tube, a 0.035-inch guidewire was inserted into the tube. After removal of the 11-Fr tube, the guidewire was put into the channel of a 10-Fr BLAKE Silicone Drain. The drain was inserted into the jejunal limb through the intrahepatic bile duct and was connected to a J-VAC Suction Reservoir. Low-pressure continued suction was applied. Patients can be discharged after insertion of the 10-Fr BLAKE Silicone Drain connected to the J-VAC Suction Reservoir. Placement of a percutaneous transhepatic biliary stent using a 10-Fr BLAKE Silicone Drain connected to a J-VAC Suction Reservoir is useful for the treatment of stenotic hepaticojejunostomy.

Abstract: AIM: To compare diverse endoscopic interventions in the management of occluded uncovered self-expanding metal stents (SEMSs) that had been placed for palliative treatment of unresectable malignant biliary obstruction.METHODS: A retrospective review was undertaken in 4 tertiary endoscopic centers to determine optimal management of different types of occluded SEMSs. The technical success of performed treatment in occluded SEMSs, the patency of the stent, the need for re-intervention and the financial costs of each treatment were analyzed.RESULTS: Fifty four patients were included in the analysis; 21 received Hanaro, 19 Wallstent and 14 Flexus. For the relief of obstruction, a plastic stent was inserted in 24 patients, a second SEMS in 25 and mechanical cleaning was performed in 5 patients. The overall median second patency rates between second SEMSs and plastic stents did not differ (133 d for SEMSs vs 106 d for plastic stents; P = 0.856). Similarly, no difference was found between the overall survival of SEMS and plastic stent groups, and no procedure-related complications occurred. Incremental cost analysis showed that successive plastic stenting was a cost-saving strategy at least in Greece.CONCLUSION: Insertion of uncovered SEMSs or plastic stents is a safe and effective treatment for occluded uncovered SEMSs; insertion of plastic stents appears to be the most cost-effective strategy.

Abstract: Pancreatic cancer is devastating due to its poor prognosis. Patients require a multidisciplinary approach to guide available options, mostly palliative because of advanced disease at presentation. Palliation including relief of biliary obstruction, gastric outlet obstruction, and cancer-related pain has become the focus in patients whose cancer is determined to be unresectable. Endoscopic stenting for biliary obstruction is an option for drainage to avoid the complications including jaundice, pruritus, infection, liver dysfunction and eventually failure. Enteral stents can relieve gastric obstruction and allow patients to resume oral intake. Pain is difficult to treat in cancer patients and endoscopic procedures such as pancreatic stenting and celiac plexus neurolysis can provide relief. The objective of endoscopic palliation is to primarily address symptoms as well improve quality of life.
