Background: Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is associated with a relatively high proportion of adverse events, and this is attributable to the lack of standardized protocols and specialized equipment. Although the outcomes of EUS-HGS may differ between patients with and those without surgically altered upper gastrointestinal anatomy, there have been no reports on this topic. The present study aimed to evaluate the efficacy and safety of EUS-HGS using our standardized method and to compare the outcomes between patients with and those without surgically altered upper gastrointestinal anatomy...

The present study aimed to observe whether optical coherence tomography (OCT)-guided angioplasty is able to provide useful clinical information beyond that obtained by angiography as well as provide recommendations for physicians that may improve treatment selection. This prospective study included 83 patients with coronary artery disease (>18 years) undergoing coronary angiography (CAG) for ST-elevation myocardial infarction (n=13), non-ST-elevation myocardial infarction (n=19), stable angina (n=22), unstable angina (n=10), silent ischemia (n=11), or elective percutaneous coronary intervention (n=8)...

Background and purpose Placement of a large-bore guiding sheath or catheter into the common carotid artery (CCA) is crucial in transbrachial carotid artery stenting (CAS). Herein, we describe technical tips for the navigation of a 6-French guiding sheath into the CCA using a tri-axial catheter system in transbrachial CAS. Materials and methods A total of 27 patients underwent transbrachial CAS. For the right side, a 6-French straight guiding sheath was navigated directly into the CCA using a tri-axial catheter system, with a 4-French Simmons catheter placed through a 6-French straight guiding catheter...

BACKGROUND: Iliac vein injury associated with pelvic fracture due to blunt trauma is an uncommon and difficult diagnosis but a life-threatening condition which often requires an emergent management. Although open repair has been traditionally used as the treatment of choice in unstable patients, it is controversial, given the difficulty injured vessel exposure in patients with significant retroperitoneal hematoma as well as tamponade effect loss associated to laparotomy. We present a challenging case of iliac vein laceration successfully treated by placement of a self-expanding covered stent...

Malignant small bowel obstruction is a common and distressing complication in advanced cancer patients. Recently, stent placement was reported to be a safe and effective alternative treatment. However, there are only a few case reports associated with stent placement in malignant jejunal obstruction. Furthermore, most patients had a history of gastrectomy before stent placement, which shortens the catheterization pathway. In our case series, we present five cases of malignant proximal jejunal obstruction in a non-surgically altered stomach in the management of fluoroscopy-guided self-expandable metallic stent placement and discuss the interventional management and clinical outcomes...

Current therapeutic strategies are insufficient for suppressing stent-induced restenosis. Here, branched gold nanoparticles (BGNP) coated self-expandable metallic stents (SEMSs) were developed for a local heat induced suppression of stent-related tissue hyperplasia. Our polydopamine (PDA) coating on SEMS allowed BGNP crystal growth on the surface SEMS. The prepared BGNP-coated SEMS showed effective local heating under near infrared laser irradiation. The effectiveness of BGNP-coated SEMS for suppressing stent-related tissue hyperplasia was demonstrated in a rat esophageal model (n=52)...

RATIONALE: Spontaneous coronary artery dissection is a highly unusual cause of acute coronary disease. It is a result of a hematoma formation within the outer third of the tunica media,with subsequent expansion leading to compression of the true lumen and resultant myocardial ischemia. PATIENT CONCERNS: We present a case of a middle-aged woman presenting with chest pain with acute anterior myocardial infarction, who did not reveal any of the cardiovascular risk factors...

BACKGROUND AND AIMS: EUS-guided gallbladder drainage (EUS-GBD) is a challenging technique for endoscopists that requires a high level of skill. A very important reason why EUS-GBD is challenging is that the gallbladder can be easily collapsed. In order to resolve this concern, we aimed to develop a retrievable puncture anchor traction (RPAT) method for EUS-GBD. We evaluated and compared the success rate, safety, and outcomes of the RPAT method for EUS-GBD against EUS-GBD without retrievable puncture anchor using a porcine model...

OBJECTIVES: Percutaneous transhepatic gallbladder drainage (PTGBD) is widely used for patients with acute cholecystitis. There is little data on the efficacy and safety of endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) replacement of PTGBD in patients who cannot undergo cholecystectomy. METHODS: This multicenter retrospective study in Japan reviewed records of patients who underwent EUS-GBD to replace PTGBD between January 2010 and December 2017. Outcomes evaluated included technical success, defined as successful stent placement between the gastrointestinal lumen and the gallbladder; clinical success, defined as subsequent removal of the percutaneous catheter; adverse events; and stent patency...

Background: Endoscopic management of pelvic abscesses not amenable to percutaneous drainage has been described. The technique employs endoscopic ultrasound (EUS)-guided placement of stents or drains, which may require multiple procedures, is cumbersome and uncomfortable for the patient. We describe the successful management of these abscesses in a single step involving EUS-guided lavage and instillation of antibiotics. Methods: Six consecutive patients with seven symptomatic pelvic abscesses not amenable to percutaneous drainage were referred for EUS-guided drainage...

OBJECTIVES: This study aimed to determine the effect on long-term survival of using optical coherence tomography (OCT) during percutaneous coronary intervention (PCI). BACKGROUND: Angiographic guidance for PCI has substantial limitations. The superior spatial resolution of OCT could translate into meaningful clinical benefits, although limited data exist to date about their effect on clinical endpoints. METHODS: This was a cohort study based on the Pan-London (United Kingdom) PCI registry, which includes 123,764 patients who underwent PCI in National Health Service hospitals in London between 2005 and 2015...

Random weakening of an intracranial blood vessel results in abnormal blood flow into an aneurysmal sac. Recent advancements show that an implantable flow diverter, integrated with a medical stent, enables a highly effective treatment of cerebral aneurysms by guiding blood flow into the normal vessel path. None of such treatment systems, however, offers post-treatment monitoring to assess the progress of sac occlusion. Therefore, physicians rely heavily on either angiography or magnetic resonance imaging. Both methods require a dedicated facility with sophisticated equipment settings and time-consuming, cumbersome procedures...

INTRODUCTION: Pancreatic fluid collection (PFC) is a common complication of acute pancreatitis. Endoscopic ultrasound (EUS)-guided drainage, which is often followed by direct endoscopic necrosectomy (DEN), has become the primary approach to treat PFC, including pancreatic pseudocysts (PP) and walled-off necrosis (WON). We aimed to determine retrospectively the short- and long-term results of patients treated in our endoscopy unit and to identify parameters that are associated with treatment efficacy and outcome...
