Placement of multiple metal stents (MS) for the management of high-grade malignant hilar biliary obstruction (MHBO) is useful,1,2 and biliary radiofrequency ablation (RFA) has been suggested to improve stent patency.3,4 However, to our knowledge, there are no reports of RFA procedures performed using a single-balloon endoscope (SBE) in patients with surgically altered anatomy. Here, we report a successful case of RFA combined with multiple MS placement using SBE in Roux-en-Y gastrectomy. This article is protected by copyright...

BACKGROUND & AIMS: Placement of an irradiation stent has been demonstrated to offer longer patency and survival when compared to an uncovered SEMS in patients with unresectable malignant biliary obstruction (MBO). We aim to further assess the efficacy of an irradiation stent compared to an uncovered SEMS in those patients. METHODS: We performed a randomized, open-label trial of participants with unresectable MBO at 20 centers in China. A total of 328 participants were parallelly allocated into the irradiation stent group (ISG) or the uncovered SEMS group (USG)...

BACKGROUND: Transjugular intrahepatic portosystemic shunt (TIPS) is considered to be well suited for the treatment of noncirrhotic portal hypertension (NCPHT) because of a usually severe portal hypertension (PHT) and a mild liver failure, but very less data are available. PATIENTS AND METHODS: Records of patients referred for TIPS between 2004 and 2015 for NCPHT were reviewed. No patient should have clinical or biological or histological features of cirrhosis. RESULTS: Twenty-five patients with a wide variety of histological lesions (sinusoidal dilatations, granulomatosis, regenerative nodular hyperplasia, obliterative portal venopathy, or subnormal liver) and a wide variety of associated diseases (thrombophilia, sarcoidosis, common variable immunodeficiency, scleroderma, Castleman's disease, early primitive biliary cirrhosis, congenital liver fibrosis, chemotherapy, purinethol intake, and congenital varices) were included...

OBJECTIVES: The palliative treatment of cholangiocarcinoma is based on stent placement with well-known procedure-related complications. Consequently, alternative energy-based techniques were put forward with controversial long-term results. This study aims to evaluate the safety and effectiveness of biliary tree laser ablation (LA) in terms of: i) absence of perforation, ii) temperature increase, iii) induced thermal damage in in vivo models. MATERIALS AND METHODS: The common bile duct and cystic ducts of two pigs were ablated with a diode laser (circumferential irradiation pattern) for 6 and 3 minutes at 7 W...

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is a common procedure that, in the United States, is traditionally performed by gastroenterologists. We hypothesized that when performed by well-trained surgeons, ERCP can be performed safely and effectively. The objectives of the study were to assess the rate of successful cannulation of the duct of interest and to assess the 30-day complication and mortality rates. METHODS: We retrospectively reviewed the charts of 1858 patients who underwent 2392 ERCP procedures performed by five surgeons between August 2003 and June 2016 in two centers...

BACKGROUND AND OBJECTIVES: Interventional endoscopic ultrasound (EUS) is a promising novel approach for intravascular interventions. The aim of this study was to assess the feasibility and safety of a EUS-guided intrahepatic portosystemic shunt (EGIPS) with portal pressure gradient measurement in a live porcine model. METHODS: The left hepatic vein (LHV) or the inferior vena cava (IVC) was punctured with a needle that advanced into the portal vein (PV). A guidewire was then inserted into the PV, and a needle knife was used to create an intrahepatic fistula between LHV and PV...

Painless jaundice is a harbinger of malignant biliary obstruction, with the majority of cases due to pancreatic adenocarcinoma. Despite advances in treatment, including improved surgical techniques and neoadjuvant (preoperative) chemotherapy, long-term survival from pancreatic cancer is rare. This lack of significant improvement in outcomes is believed to be due to multiple reasons, including the advanced stage at diagnosis and lack of an adequate biomarker for screening and early detection, prior to the onset of jaundice or epigastric pain...

REVIEW
Amy R Deipolyi, Anne M Covey
The optimal palliative intervention for malignant biliary obstruction is internal drainage by placement of a metallic stent. For patients with hilar biliary obstruction or low bile duct obstruction in whom endoscopy is not feasible, a percutaneous transhepatic approach in interventional radiology is preferred. This article reviews the rationale for this approach, periprocedural management, and techniques to optimize stent patency.

Mucoceles of the paranasal sinus can be managed endoscopically with an extremely low recurrence rate. Frontal sinus mucoceles can sometimes be prevented from closing and reforming by stenting, which to the best of our knowledge has not yet been reported in the maxillary sinus. We describe the cases of 5 patients-3 men and 2 women, aged 47 to 75 years (mean: 59.6)-with a recurrent and intractable maxillary sinus mucocele that was managed with biliary T-tube stenting. The indications for stenting included recurrent episodes of mucocele with or without a lateral location with a relatively thick bony wall...

BACKGROUND: Both fully covered (FC) and partially covered (PC) self-expandable metal stents (SEMSs) are now commercially available for distal malignant biliary obstruction (MBO). While FCSEMS can be easily removed at the time of re-interventions, it is theoretically prone to migration. However, few comparative data between FC and PC SEMSs have been reported. AIMS: The aim of this study was to compare clinical outcomes of FCSEMS with those of PCSEMS. METHODS: This was a multicenter, prospective study of FCSEMS for unresectable distal MBO with a historical control of PCSEMS, which was previously reported as the WATCH study...

BACKGROUND/AIM: Percutaneous cholecystostomy [percutaneous transhepatic gallbladder drainage (PTGBD)] is the treatment of choice in surgically unfit patients with acute cholecystitis. However, PTGBD tube removal after symptoms resolution results in 41-46% recurrence. This study aims to demonstrate the feasibility of the conversion of PTGBD to transmural endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) using plastic stents in patients unfit for cholecystectomy. PATIENTS AND METHODS: Patients who underwent internal transmural EUS-GBD as a conversion from PTGBD were reviewed...
