NCT ID: NCT04712253 Completed - Biliary Condition Clinical Trials

International Study to Evaluate Outcomes and Safety of Patients Undergoing ERCP Using a Single-use Cholangioscope and Single-use Duodenoscope

MESE
Start date: January 27, 2021
Phase:
Study type: Observational

Since its introduction more than 40 years ago, endoscopic retrograde cholangiopancreatography (ERCP) has fundamentally changed the treatment of biliopancreatic diseases. Since late 1970s there have been sporadic reports of nosocomial infections linked to endoscopic procedures, the majority caused by inadequate reprocessing of endoscopes. Infections due to multidrug-resistant organisms (MDROs) however have increasingly become a concern in health care, including in gastrointestinal (GI) endoscopy. Since 2010, reports of individual cases and serial outbreaks of MDRO infections associated with ERCP have been published worldwide. This is because, unlike a gastroscope or colonoscope, the duodenoscope is a complex instrument with unique mechanical features incorporated at the distal tip. This includes a recessed space containing an elevator, a wire cable that moves the elevator, working channel, and most recently, a seal that prevents contamination of the elevator wire channel. This complex design creates hard-to-reach areas that make optimal mechanical cleaning and disinfection difficult. With the aim of overcoming these issues, a single-use duodenoscope (EXALT Model D, Boston Scientific Corporation, Marlborough, Massachusetts, USA) has been developed in the United States of America (USA) and approved by the United States Food and Drug Administration (FDA) for clinical use in December 2019. Different studies evaluating this new device, including randomized clinical trials (RCTs), have already been published, which have confirmed that single-use duodenoscopes represent an alternative to reusable duodenoscopes for performing low-complexity ERCP procedures in experienced hands. Digital Single Operator Cholangioscopy (D-SOC) using the single use Spyglass DS II (Boston Scientific Corporation, Marlborough, Massachusetts, USA) is a diagnostic and therapeutic modality which allows for direct endoscopic visualization of the biliopancreatic ductal system. The principal diagnostic indication of D-SOC are bile duct or pancreatic strictures and unclear filling defects, adding direct endoscopic appearance data to biopsy sampling or brush cytology in order to improve the diagnostic yield. The major therapeutic indication for D-SOC is lithotripsy for difficult biliary and pancreatic stones. However, cholangioscopy increased the risk of post ERCP cholangitis. Bacteremia was suggested to be specifically related to cholangioscopy in 13.9% of 72 patients, based on serial blood samplings, and to be associated with biopsy sampling and strictures. For this reason, the recent European Society of Gastrointestinal Endoscopy (ESGE) guideline suggests that patients should be considered to be at high risk for post-ERCP cholangitis when cholangioscopy is performed. Presently, there are very few clinical reports about technical and clinical outcome of ERCPs performed with single use duodenoscope and there is complete lack of data about efficacy, safety and adverse events of the combination of the new single-use duodenoscope and the Spyglass DS II. The aim of this multicentric retrospective study was to evaluate the technical success, clinical outcome and rate of adverse events of this procedure.

NCT ID: NCT04709666 Completed - Biliary Condition Clinical Trials

Difficult Biliary Cannulation in Patients With Distal Malignant Biliary Obstruction: an Underestimated Problem

DBC 01
Start date: January 1, 2014
Phase:
Study type: Observational

Endoscopic retrograde cholangiopancreatography (ERCP) is the primary therapeutic procedure for many bilio-pancreatic diseases, and requires the first crucial step of the successful deep cannulation of the common bile duct through the Vater's papilla. Difficult biliary cannulation (DBC) is a well-recognized risk factor for adverse events (AE) and cannulation failure, which has been reported in about 11% of ERCP regardless of their indication and a relevant heterogeneity in definition of DBC is present in the available studies. More recently, DBC during ERCP has been precisely defined by the European Society of Gastrointestinal Endoscopy (ESGE) as follows: more than 5 contacts with the papilla whilst attempting to cannulate; more than 5 minutes spent attempting to cannulate after visualization of the papilla; more than one unintended pancreatic duct cannulation or opacification (4). To date, the rate of DBC has not been calculated for specific sub-groups of ERCP indications. In particular, the rate of DBC in the setting of distal malignant biliary obstruction (DMBO), a frequent indication for ERCP, has not yet been described. DMBO is generally secondary to pancreatic adenocarcinoma, distal cholangiocarcinoma, ampullary carcinomas or adenopathy/metastasis from other cancers, and could potentially increase the complexity of the procedure as the tumor compression or infiltration alter the normal duodenal/papillary anatomy or determine duodenal rigidity. In this study, we aimed to investigate the rate of DBC and the outcome of patients undergoing ERCP for DMBO.

NCT ID: NCT04708249 Completed - Sexual Dysfunction Clinical Trials

D-chiroinositol Administration in Hypogonadal Males

Start date: January 18, 2021
Phase: N/A
Study type: Interventional

D-chiroinositol (DCI), is known as second messenger of insulin pathway, but recently several works have reported the influence of DCI on steroidogenesis. In particular, the DCI capabilities to regulate aromatase expression and testosterone biosynthesis are arising. In this regard, DCI administration in case of reduced levels of testosterone, could be a good therapeutic opportunity. For this reason, the treatment of Late-Onset Male Hypogonadism (LOH) in undoubtedly an interesting target. LOH is a reduction of testosterone level due to advancing age, currently treated with Testosterone Replacement Therapy (TRT). Unfortunately, there is a lack of information about TRT safety, especially in older men. For these reasons, the aim of this study is to evaluate the effect of DCI treatment on testosterone accumulation in LOH patient.

NCT ID: NCT04701463 Completed - Obesity Clinical Trials

A Specialized Amino Acid Mixture on Body Composition and Skin State in Overweight and Obese Class I Postmenopausal Women

Start date: January 15, 2020
Phase: N/A
Study type: Interventional

The use of dietary amino acids has been explored for therapeutic and safety intervention of obesity and obesity-induced dysfunction. In particular, 3 molecules have been shown to be effective both in the animal model and in humans, in promoting the loss of fat mass, specifically visceral adipose tissue, and in maintaining free fat mass: arginine, glutamine and leucine (and its metabolite beta hydroxy methyl butyrate, HMB). The aim of this study was to evaluate the efficacy in terms of fat mass, in particular Visceral Adipose Tissue reduction, as primary end point, in obese patients following the administration of specific food for special medical purposes (FSMP) for muscle recovery, consisting of arginine, glutamine and HMB. The secondary end point is the evaluation of skin state, by a validate self-reported questionnaire survey to assess skin, after 4- weeks intake of this FSMP.

NCT ID: NCT04700943 Completed - Thoracic Surgery Clinical Trials

Ultrasound Assessment of Diaphragmatic Dysfunction in Regional Anesthesia

Start date: February 1, 2019
Phase:
Study type: Observational

Awake thoracic surgery is a feasible and safe alternative to general anesthesia for pulmonary biopsy in interstitial lung disease patients, but there is still no evidence as to its superiority in terms of outcome. However, there is extensive literature about the effect of anesthetic drugs and surgery on diaphragmatic function. Furthermore, in thoracic surgery, diaphragmatic dysfunction was associated with a higher occurrence of postoperative pulmonary complications. To assess the impact of general anesthesia on diaphragmatic function, the investigators conducted an observational prospective trial. The investigators measured both diaphragmatic excursion and Thickening Fraction at baseline and 12 hours after surgery together with pulmonary function tests and gas exchange data.
