Purpose To prospectively test in a porcine model the hypothesis that bariatric embolization with commercially available calibrated microspheres can result substantial suppression of systemic ghrelin levels and affect weight gain over an 8-week period. Materials Methods The institutional animal care use committee approved this study. Twelve healthy growing swine (mean weight, 38.4 kg; range, 30.3–47.0 kg) were evaluated. Bariatric was performed by infusion 40-μm selectively into gastric...
The purpose of this project was to determine whether bacteriophage can reduce bacterial colonization and biofilm formation on central venous catheter material. Twenty silicone discs were inoculated for 24 h with broth culture Methicillin sensitive staphylococcus aureus (0.5 McFarland standard). inoculate aspirated placed into two equal groups h: (1) untreated controls; (2) treatment (staphylococcal K, propagated titer > 108). At the completion experiment processed quantitative culture....
Gastric intestinal metaplasia (GIM) is the most common precursor of gastric cancer. Our aim to determine if presenting symptoms predict cancer lesions in a high-risk population.Consecutive unique patients evaluated by endoscopy for upper gastrointestinal at Los Angeles County Hospital between 2010 and 2014 were evaluated. Presenting classified as low- or depending on procedure indication coded using Clinical Outcomes Research Initiative (CORI) system. Endoscopy histology results used...
Objectives Distinguishing neuroendocrine tumors (NETs) and other pancreas lesions from adenocarcinomas via endoscopic ultrasound (EUS) requires additional tissue for special staining processing. Our aim was to determine if main pancreatic duct (PD) diameter on EUS helps differentiate NET unusual adenocarcinoma. Methods We evaluated 30 consecutive patients diagnosed with or by 90 matched who were found have Dilated PD defined as greater than 3 mm. Multivariate logistic regression used...
Endoscopic ultrasound (EUS) is routinely used for fiducial marker placement (FMP) to guide stereotactic radiation of pancreatic tumors, but EUS-FMP explicitly surgery has not been studied in a prospective, controlled manner. Multipurpose EUS systems have developed that facilitate simultaneous at the time biopsy. We aimed evaluate feasibility resection.

Introduction: Guidewire fracture during ERCP is an uncommon event and few cases of guidewire within the pancreatic duct have been described. Case Description/Methods: 40-year-old woman with painful chronic calcific pancreatitis, a severe stricture in head stones. During ERCP, attempt was made to deploy stent, this maneuver, most distal 15cm 0.25 inch straight wire fractured remained retained inside above stricture. This appeared coiled body, sheared end embedded side branch. Numerous...
Introduction: Endoscopic placement of metal stents can improve dysphagia and quality life in patients with symptomatic esophageal strictures. Traditional have large diameters (≥14 mm), which be poorly tolerated when the stricture is very narrow or located cervical esophagus. Fully covered self-expandable biliary (fc-SEMBS) anti-migration fins (AMF) anecdotally been used to reduce these issues. However, data on off-label use fc-SEMBS scarce. Therefore, we aimed assess efficacy safety for...

INTRODUCTION: The initial endoscopic treatment of ascending cholangitis is controversial. It has been proposed that management should be limited to decompression alone while the alternative additionally perform sphincterotomy and/or stone removal address underlying etiology. Our aim was compare effectiveness and safety combined with other endotherapy for cholangitis. METHODS: We systematically searched Embase, Medline, Cochrane Library, ClinicalTrials.gov from inception April 22, 2019....
Introduction: Localization of small pancreatic tumors is challenging due to minimally invasive approach resection. EUS-guided fiducial marker placement (EUS-FMP) aid intraoperative identification has been proposed, but its feasibility not explored in a controlled prospective manner. The objective this study determine the technical EUS guided mark pancreas 20 patients and assess utility during surgery (ClinicalTrials.gov Identifier: NCT02863783) (Figure 1). Methods: In study, we enrolled...
