Active clinical trials for "Constriction, Pathologic"

Vaginal stenosis is one of the most prevalent side effects of pelvic radiation, affecting about one third of women. In this randomized controlled trial, the effect of a pelvic physiotherapy protocol on an incidence rate of vaginal stenosis in women with gynecological cancer undergoing gynecological brachytherapy. In addition, the investigators will explore an improvement in quality of life, sexuality, and contractile function of the pelvic floor muscles.

There are two arms in our trial, DCB group, BMS group.The investigators are going to investigate the safety and efficacy of all groups at 6 months and 12 months.

There is no international consensus on evaluation and surgical treatment of Lumbar Spinal Stenosis (LSS). The indication for operative treatment is relative, and the variation in surgical rates and procedures is significant, both within and between countries. Understanding practice-based variety is critical since these differences may reflect a disparity in quality of the health care in different institutions, regions, or countries. Norway, Sweden, and Denmark do all have National spine registers for research and quality assessment. Comparing indications for surgery, selected procedure, patient reported outcomes, and factors predicting outcome after surgery for LSS between these countries could provide information about optimal indications and strategy for surgery. Register-based studies have advantages such as large sample sizes and high external validity, but also limitations such as lower follow-up rates, and inferior data quality compared to clinical trials. Hypotheses: Between these three countries, there are no differences in (i) indications for surgery, (ii) patient-reported outcome after surgery or (iii) risk factors associated to outcome are similar.

The aim of this study is to perform a multicentre, prospective, randomized, placebo controlled, double-blinded study to demonstrate the potential and beneficial effects of OVB in the prevention of recurrence of anastomotic stricture in children operated for esophageal atresia with an anastomotic stricture.

The study was designed as a prospective cohort study. The effects of hot and cold ischemic times during live donor liver transplantation on postoperative 1-3 and 6 month follow up biliary complications will be investigated.

This study is safety and proof-of-concept study for oral prednisolone in the treatment of esophageal stricture after esophageal surgery. The patients who develop the severe esophageal strictures from 28 days after esophageal surgery are included. Primary outcomes are Safety and Success rate of this treatment.

BACKGROUND.- The frailty syndrome (FS) associates an increase in morbidity and mortality in the elderly patient. When severe and symptomatic, aortic stenosis (AS) is a disease with poor prognosis, the most frequent cause of heart surgery in the elderly and associates high health costs. No variables have been identified as determinants of morbidity and mortality of these patients and there are not algorithms developed for treatment decision-making in this particular population. The FS as a functional reserve indicator could be a prognostic and interventional treatment tolerance marker, and should be included in the selection of patients for surgical treatment. The FS and cardiovascular disease (CVD) share biological substrates among which an inflammatory state associates poor prognosis. OBJECTIVES .- To evaluate the effectiveness of the diagnosis of FS to characterize the prognosis of elderly patients with severe symptomatic AS representative of clinical practice. In addition, to examine the contribution of an inflammatory state to the relationship of FS with the prognosis of severe, symptomatic AS. METHODS .- Prospective study during 12 months of 200 patients > 74 years old with severe symptomatic AS. During the index visit the main clinical characteristics will be recorded and in addition we will perform a comprehensive geriatric assessment, FS assessmet according to Fried et al criteria (strength, walking speed, physical activity, fatigue, unintentional weight loss) and determination of inflammatory markers (C-reactive protein and interleukin-6). During follow-up, measures of functional impairment (basic and instrumental activities of daily living, walking speed and timed set up & go test), hospitalizations, death and quality of life will be determined.

Conventional peroral methods to visualize biliary strictures are not feasible in some patients with altered anatomy or biliary obstruction, and percutaneous transhepatic cholangioscopy can be used as an alternative procedure. This study aimed to retrospectively review the use of percutaneous transhepatic cholangiography using the SpyGlass DS technology (S-PTCS) during a 5-year period at a Danish tertiary referral center.

Device: EluNIR Ridaforolimus Eluting Coronary Stent System - (hereafter referred to as EluNIR) 2.25 mm diameter (8 mm, 12 mm, 15 mm, 17 mm, 20 mm, 24 mm, 28 mm and 33 mm length) Objectives: To further assess the safety and efficacy of the small diameter (2.25 mm) Ridaforolimus Eluting Stent - EluNIR. Subject Population: Subjects who underwent PCI for angina (stable or unstable), silent ischemia (in absence of symptoms a visually estimated target lesion diameter stenosis of ≥70%, a positive non-invasive stress test, or FFR ≤0.80 must be present), NSTEMI, and recent STEMI (>24 hours from initial presentation and stable) with attempted implantation of a 2.25 mm diameter EluNIR stent. Trial Design and Methods: This is a prospective, multi-center, single-arm, open-label clinical trial. Clinical follow-up for all patients will be performed at 30 days 6 months, and 1 year after the procedure.

The purpose of this retrospective, observational study is to compare the profit of BAV and TAVI in different subtypes of serve aortic stenosis.
