Filter by:The management of biliary strictures depends on their correct pre-operative evaluation which remains challenging. Despite the emerging multitudes of new diagnostic opportunities- modalities we have today, there is still a large number of biliary stenosis misdiagnosed with a profound negative impact on the patients´ outcome. The study aims to proove the feasibility and to evaluate the impact of Fluorescent In Situ Hybridization (FISH) on the tissue diagnostic of biliary strictures.
Patients undergoing surgical aortic valve replacement (sAVR) with concomitant coronary artery disease (CAD) are known to have higher mortality rates compared to patients without CAD. This same phenomenom has not been clearly mapped in patients with CAD that goes through a transcatheter aortic valve implantation procedure.
Pulmonary artery sling is a rare congenital pulmonary vascular malformation, often associated with tracheal or bronchial stenosis. Surgical treatment of pulmonary artery sling with tracheal stenosis has a high risk and a relatively poor prognosis. This article aims to explore the relationship between the index of tracheal and left pulmonary artery stenosis and the surgical effect of pulmonary artery sling with tracheal stenosis. Methods: Retrospective analysis of the cases of pulmonary artery sling surgery in our center from January 2010 to December 2018. Before operation, routine cardiac enhancement CT examination was performed, and the diameter of the left pulmonary artery and the tracheal stenosis were measured on the CT tomogram respectively, and the ratio of the degree of tracheal stenosis / left pulmonary artery stenosis (T / P) was calculated, combining the surgical method and clinical prognosis analyzed and discussed.
The study will consist of two parts: - In Study A, objectively assessed physical activity, gait, balance, range of movement of specific joints during walking and neurophysiological findings between patients with cervical spine stenosis (CSS) without myelopathy who will be treated conservatively and patients with stenosis and signs of myelopathy who are candidates for surgical Treatment will be compared. - In Study B, the 6-month changes in the same outcomes in patients treated conservatively (from the first specialist consultation until 6 months later) and in patients treated surgically (preoperative day and 6-month post-operatively) will be quantified.
Total of 60 patients with a diagnosis of spinal stenosis is planned for 30 patients, with physical therapy modeling and exercise, and 30 patients with surgical treatment. Patients will be evaluated by the same physician 5 times, before early primary treatment, 1st month, 3rd month, 6th month and 12th month after treatment.
Wearing a penile ring is justified by international societies of Urology (AFU, EAU, AUA) only for the treatment of erectile dysfunction with vacuum. In this case, it is a constriction rubber band that can only be worn for 30 minutes. Nowadays, wearing a cockring device for recreational purposes can lead to complications secondary to ischemia caused by strangulation of the penis and/or scrotum. The variety of devices and materials used (metallic and/or alloys in particular) sometimes makes it difficult to remove them, requiring expensive surgery and dedicated equipment. There is no official recommendation for the management of these complications.
The aim of the present study is to find out the influence of sarcopenia on outcomes of neuroplasty in patients with lumbar spinal stenosis.
Anastomotic stricture is a common complication following foregut surgery. The standard of care for these benign foregut anastomotic strictures is balloon dilatation. However, re-stenosis of strictures is also common, requiring frequent repetition of balloon dilatation. Cryotherapy is a novel therapy that may improve clinical outcomes following dilatation. The purpose of the present study is to conduct a randomized controlled trial to characterize the impact of cryotherapy on clinical outcomes and complications for benign anastomotic strictures following esophagectomy, gastrectomy, and bariatric surgery.
Our ultimate goal is to design a multi-center randomized trial to test the hypothesis that targeted testing for transthyretin cardiac amyloid (ATTR) will improve survival and health status among aortic stenosis patients who undergo transcatheter aortic valve replacement (TAVR). The hypothesis of this pilot study is to evaluate if invasive cardiac hemodynamics obtained after TAVR, by using the AortoVentricular index (AVi), can be used as a novel test to help identify participants with ATTR. Aim 1. To determine if an abnormal AVi value can identify ATTR among aortic stenosis patients undergoing TAVR. Aim 2. To determine if s' from echocardiography plus AVi can enhance the prediction of ATTR among aortic stenosis patients undergoing TAVR. Aim 3. To design a pilot trial to improve patient outcomes after TAVR by targeted testing for ATTR.
Elastography is a new non-invasive medical technique for measuring the stiffness at a distance from a tissue. Recent advances in the development of elastography sequences for cardiac exploration suggest a more clinical approach to cardiac elastography. This study propose to compare myocardial stiffness of a group of coronary bypass patients without hypertrophic left ventricular remodeling or sequelae of myocardial infarction versus a group of patients who should benefit from a surgical aortic valve replacement for aortic stenosis. The hypothesis is that the physiological adaptation to pressure overload constituted by aortic stenosis is responsible for a significant increase in myocardial stiffness compared to a reference group.
