Filter by:The study involves the planned use of a new microwave-based device during colonoscopy procedures in a small group of patients to assess the preliminary safety of its use and lack of normal clinical practice modification. The device is a final design version, which has been previously tested in several preclinical studies, including: phantom studies, an ex vivo study with human tissues, and an in vivo study with animal model (pig).
Chronic rhinosinusitis with nasal polyps is a common nasal comorbidity with a wide range of symptoms that might cause severe distress and disabilities for patients. Many patients undergo repeated courses of systemic steroids and are exposed to various adverse effects. many cases finally revert to surgery. Budesonide was safely used as a nasal wash in cases of nasal polyps, our aim to determine If intrapolyp injection is a better method for delivering budesonide.
Currently, hemorrhage remains the most common postoperative complication in patients with colon polyps, with an incidence of approximately 1.5%. The main reasons for postoperative hemorrhage are: the patient's own condition, the nature of the polyp and the operation. The number of patients treated for colon polyps has increased, postoperative care is confusing, medical resources are wasted, and the time span for postoperative diet recovery is large. However, studies on the effect of postoperative dietary recovery timing on postoperative polyp bleeding are rare.
Hypoxia is the most common adverse event in gastrointestinal endoscopes sedated with propofol. The nasal mask oxygen kit has good sealing to ensure an adequate oxygen supply and is convenient and economical.The aim of this randomized study was to determine whether the nasal mask oxygen kit reduces the incidence of hypoxia in gastrointestinal endoscopes procedures.
in patients with chronic rhinosinusitis with nasal polyps and concomitant asthma, they have a poor therapeutic response and a higher recurrence rate, and treatment in these patients often fails. investigators conducted this study to survey the efficacy of Omalizumab (anti IgE) on patients with refractory nasal polyp to confirm its efficacy entering to treatment guidelines.SNOT-22 score will measure at screening; on day 1; and at weeks 4, 8, 16, and 24 (point range, 0-110, with lower scores indicating better disease control and quality of life .
Correct endoscopic prediction of the histopathology and differentiation between benign, pre-malignant, and malignant colorectal polyps (optical diagnosis) remains difficult. Artificial intelligence has great potential in image analysis in gastrointestinal endoscopy. Aim of this study is to investigate the real-time diagnostic performance of AI4CRP for the classification of diminutive colorectal polyps, and to compare it with the real-time diagnostic performance of commercially available CADx systems.
This is a multi-center, randomized, double blind, placebo-controlled, dose escalation study to evaluate the safety, tolerability, PK, PD, immunogenicity and preliminary efficacy of CM326 in patients with chronic rhinosinusitis with nasal polyps.
The aim of this study is to investigate if the use of artificial intelligence (AI) in colonoscopy improves the polyp detection rate, and if the use of AI has a learning effect.
With the continuous development of microsurgery, supporting laryngoscopy acoustic polyp removal has become a very mature clinical operation. The operation has small trauma, short operation time, fast turnover and needing to wake up as soon as possible, but the supporting laryngoscopy has great stimulation to the throat and great hemodynamic fluctuations. This study aims to evaluate the efficacy of ultrasound guided superior laryngeal nerve block as an adjuvant to general anesthesia during vocal cord polypectomy by laryngoscopy.
This study will evaluate the efficacy and safety of depemokimab (GSK3511294) in participants with CRSwNP.
