Active clinical trials for "Biliary Tract Diseases"

Purpose: To assess the utility of a new medical device that monitors a patient's breathing during medical procedures in which a patient is sedated, but not mechanically ventilated. In minor procedures, such as endoscopy (where the doctor examines a patient's digestive tract by a TV camera inserted through the mouth), patients do not require general anesthesia, in which a machine would take over their breathing while they are unconscious for surgery. However, during endoscopic procedures it is sometimes difficult for the anesthesiologist to monitor the patient's breathing-specifically, to monitor changes in breathing patterns and the adequacy of breathing. In endoscopy procedures, the room is darkened, and the patient's mouth is generally occupied by the endoscope. While the anesthesiologist can listen to the patient's breathing sounds with a stethoscope, this type of monitoring can only be done periodically, and there is limited ability to gauge the adequacy of ventilation. This study will use the ExSpiron Respiratory Volume Monitor (RVM), which measures non-invasive minute ventilation (MV), tidal volume (TV) and respiratory rate (RR), in patients undergoing an endoscopic procedure to provide additional information regarding the effects of clinical interventions such as drug administrations or airway maneuvers on the patient's respiratory status. For patients who give informed consent, study participation means that they will have a PadSet consisting of 3 electrodes applied to the chest. Another component, a nasal cannula (a thin clear plastic tube that goes under the nose) will give patients supplemental oxygen, and is standard of care for endoscopy at UVM Medical Center. Patients will then be asked to breathe in and out of a portable spirometer (breath meter) for 30 seconds up to five times. This data will be compared to data recorded by the monitor to confirm that the monitor is recording accurately. The procedure will then go forward in the normal fashion. Patients will be randomly placed into one of two groups. In the first group during the procedure, the anesthesiologist will not be able to see the numbers (MV, TV, and RR) displayed screen of the monitor, so the data will not be used to guide the patient's clinical care. In the second group, the anesthesiologist will be able to see the RVM measurements of MV, TV, and RR to evaluate the effect of the interventions. Monitoring for both groups will continue in the recovery room, until discharge.

To document indications for cholangioscopy and clinical utility of the SpyGlass Direct Visualization System in China when used per standard of practice. Prospective, Post market, Multi-center, Non-randomized Study

The aim of this study is to compare sedation efficiency, safety and satisfaction by both endoscopist, assistants, and the patients between continuous infusion and intermittent bolus injection of propofol for deep sedation during ERCP.

Spanish registry of resorbable stent implantation in biliary benign strictures. This registry is sponsored by the Spanish Society of Vascular and Interventional Radiology (SERVEI) and conducted by the Research Group GITMI (Group of Research in Minimally Invasive Techniques) of the University of Zaragoza (Spain). A software tool hosted on the official website of SERVEI and the journal Intervencionismo will be used for data collection a(https://estudios.watsoncme.com).

This is a prospective observational longitudinal study Aim of the study is to collect information: on the organization models of the Endoscopic Units performing ERCP in Italy on the previous and/or ongoing training of the endoscopists performing ERCP on the clinical characteristics of patients undergoing ERCP in Italy as well as on the outcome

A prospective, multi-center registry for subjects undergoing Endoscopic retrograde Cholangiopancreatography (ERCP) and cholangioscopy for known or suspected pancreaticobiliary disease.

Background:The aim of the study is to value the application of three-dimensional visualization and three-dimensional printing in the hepatobiliary and pancreatic surgery.Method：From January 2016 to December 2018,the clinical data of 200 patients with the hepatobiliary and pancreatic diseases will be collected.All the patients received abdominal CT scanning and 3D reconstruction. Then we used the 3D reconstruction model and the 3D printed model based on the 3D reconstruction model in the operation planning and the operation.The clinical data include operative time, intraoperative blood loss,and postoperative complications after surgery.

ERCP with brush cytology has a poor to moderate accuracy in unclear biliary lesions. Endoscopic ultrasound (EUS) with fine needle aspiration (FNA) for cytology may override some of these shortcomings. The current prospective study, performed in a tertiary University center, aims to study the feasibility, the accuracy and the clinical value of combinatory ERCP and EUS in unclear biliary lesions.

The investigators included children with living donor liver transplantation (LDLT) from January 1, 2018 to July 31, 2022 as a retrospective cohort, and the group from August 1, 2022 to June 30, 2023 as a prospective cohort. The investigators collected the demographic and clinicopathological data of donors and recipients, and determined the risk factors of early postoperative delayed recovery of hepatic function (DRHF) by univariate and multivariate Logical regression analyses.

The purpose of this study is to establish the surgical risk factors and differences between different diseases in elderly patients submitted to elective surgery in our institution.
