PURPOSE: We aimed to evaluate the safety and effectiveness of fluoroscopy-guided gastroduodenal metallic stent placement with different approaches in malignant obstruction. METHODS: We retrospectively assessed 53 patients (33 men and 20 women; mean age, 58.7±15 years) who underwent stent placement between February 2004 and April 2014. All patients had unresectable tumors. The most common causes of obstruction were gastric (38%) and pancreatic cancers (36%). Uncovered self-expandable metallic stents (SEMS) were placed under fluoroscopic guidance...

A newly developed short double-balloon enteroscope with a working channel enlarged to a diameter of 3.2 mm is a novel innovation in stent placement for patients with surgically altered anatomies. Herein, we report three patients in whom this new scope contributed to an efficient technique and ideal treatment. In the first case, the double guidewire technique was efficient and effective for multiple stent placements. In the second case, covered self-expandable metal stent (SEMS) placement, which is the standard treatment for malignant biliary obstruction, could be performed in a technologically sound and safe manner...

Background/Aims: Controversy still exists regarding the benefits of covered self-expandable metal stents (SEMSs) compared to uncovered SEMSs. We aimed to compare the patency and stent-related adverse events of partially covered SEMSs (PC-SEMSs) and uncovered SEMSs in unresectable malignant distal biliary obstruction. Methods: A total of 134 patients who received a PC-SEMS or uncovered SEMS for palliation of unresectable malignant distal biliary obstruction were reviewed retrospectively...

Background and study aim Percutaneous transhepatic biliary drainage (PTBD) is a rescue procedure after a failed endoscopic retrograde cholangiopancreatography. As PTBD causes patient discomfort, conversion of the PTBD to internal biliary stenting (PTBDS) may be required; however, PTBDS is sometimes difficult because of the tight stricture. We evaluated the efficacy and safety of conversion of external PTBD to endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) after failed PTBDS. Patients and methods A total of 16 patients with malignant distal biliary obstruction who underwent conversion of external PTBD to EUS-HGS after failed PTBDS were enrolled from two institutions in Korea and Japan...

BACKGROUND: Pancreatitis is the most frequent complication due to ERCP. Pancreatic duct stent placement has been described as a preventive measure. There is also evidence pointing towards the preventive effect that early precut may provide. AIM: To determine and compare the cost-effectiveness of an early precut approach versus pancreatic duct stent placement for the prevention of post-ERCP pancreatitis. METHODS: This was a multicenter, randomized-controlled pilot study with a cost-effectiveness analysis performed between early precut (group A) and pancreatic duct stent (group B) for the prevention of pancreatitis in high-risk patients...

Although it has been reported that endoscopic double stenting using a self-expandable metallic stent (SEMS) for gastroduodenal and biliary obstruction is useful [1-2], the efficacy and safety of performing double stenting using balloon enteroscopy is uncertain in patients with surgically altered anatomy. We describe a patient who had undergone gastrectomy and then underwent endoscopic double stenting for gastrojejunostomy anastomotic and biliary obstruction. A man in his 50s with a history of having undergone distal gastrectomy with Roux-en-Y reconstruction because of gastric cancer developed gastrojejunostomy anastomotic obstruction due to local anastomotic recurrence and peritoneal dissemination (Fig...

OBJECTIVES: The clinical impact of catheter based radiofrequency ablation (RFA) under ERCP guidance has been recently reported, however severe adverse events have also been noted. If tumor is not present in the biliary tract, severe adverse events such as perforation or bleeding due to vessel injury around the biliary tract may occur. In addition, the effectiveness of RFA may not be sufficient based solely on radiographic guidance. The aim of this study was to evaluate the actual feasibility of intraductal RFA by peroral cholangioscope (POCS) evaluation before/after RFA...

Major biliary complications that require surgical intervention after hepaticojejunostomy are rare and technically challenging. While the hepaticojejunostomy can be refashioned in most patients requiring surgical reexploration after anastomotic dehiscence, a selected few may require a portoenterostomy, which involves anastomosis of the jejunum to a decapsulated area of the liver to establish a conduit from the intrahepatic bile ducts to the intestine. Herein, we describe the technique where a portoenterostomy has been used to restore bilioenteric continuity in three patients where reconstruction with a hepaticojejunostomy was not feasible...

Anthony M Esparaz, Muneeb Ahmed
Local and systemic reactions to implanted metallic devices, particularly to those containing nickel, are well documented. Metal ions are released due to exposure of the metal to blood, proteins, other body fluids, and sheer mechanical stress. Metal ions then complex with native proteins and become antigens, which can elicit hypersensitivity reactions. Another case report depicts a specific allergic complication (early stent occlusion) related to metallic biliary stent implantation. We present a case of allergic symptoms, associated with eating, in a patient who developed nickel sensitivity after biliary metal stent placement confirmed by allergic skin testing to the same metallic biliary stent placed one year earlier...

PURPOSE: To describe outcomes of patients with malignant biliary obstruction who undergo salvage percutaneous biliary drainage after occlusion of endoscopic biliary stents. MATERIALS AND METHODS: A single-center retrospective review was performed of 47 patients (25 men, 22 women) who underwent percutaneous biliary drainage for recurrent obstruction after endoscopic stent placement between 2005 and 2015. Primary malignancies were bile duct (n = 13), colorectal (n = 11), gallbladder (n = 7), pancreas (n = 5), hepatocellular (n = 4), and other (n = 7)...

BACKGROUND AND AIMS: Few reports describe the endoscopic double stenting procedure for malignant biliary and duodenal obstructions. We evaluated the clinical outcomes from double stenting, and analyzed the risk factors for biliary stent dysfunction following double stenting. METHODS: Eighty-one patients who underwent endoscopic double stenting for malignant biliary and duodenal obstructions were retrospectively analyzed. We determined the stent dysfunction rate and the biliary stent dysfunction risk factors, and analyzed the endoscopic reintervention results...

REVIEW
Kenneth V I Rolston
Solid tumors are much more common than hematologic malignancies. Although severe and prolonged neutropenia is uncommon, several factors increase the risk of infection in patients with solid tumors, and the presence of multiple risk factors in the same patient is not uncommon. These include obstruction (most often caused by progression of the tumor), disruption of natural anatomic barriers such as the skin and mucosal surfaces, and treatment-related factors such as chemotherapy, radiation, diagnostic and/or therapeutic surgical procedures, and the increasing use of medical devices such as various catheters, stents, and prostheses...

AIMS: Pre-operative biliary drainage (PBD) can relieve adverse effects of cholestasis, however carries risk of procedural complications. Metal stents have wider lumens and longer patency, although plastic stents (PS) may still be useful for short term drainage. We reviewed outcomes from PBD at our centre. METHODS: Patients with symptomatic cholestasis and those likely to wait longer than 2 weeks for surgery treated with PBD between January 2011 and May 2015 were included...

Biliary leaks are uncommon but morbid complications of pancreaticoduodenectomies, which have historically been managed with percutaneous drainage, reoperation, or a combination of both. We report a de novo percutaneous-endoscopic hepaticojejunostomy from an anomalous right hepatic duct injured during pancreaticoduodenectomy to the afferent bowel limb. The percutaneous-endoscopic hepaticojejunostomy was stented to allow for tract formation with successful stent removal after 5.5 months. One year after the creation of the percutaneous-endoscopic hepaticojejunostomy, the patient remains clinically well without evidence of biliary leak or obstruction...

BACKGROUND: Palliation for inoperable malignant distal biliary strictures can be achieved with self-expandable metal stents (SEMS) and plastic stents (PS). This is a meta-analysis to compare PS and SEMS. The aim of the study is to compare clinical outcomes in patients with SEMS and PS. METHODS: Study selection criteria were studied using SEMS and PS for palliation in patients with malignant distal biliary stricture. For data collection and extraction, articles were searched in Ovid journals, Medline, Cochrane database, and Pubmed...
