Filter by:Endoprosthesis treatment of aortic pathologies has become the reference in the vast majority of situations. The success of this treatment is conditioned by the choice of the endoprosthesis which must be as adapted as possible to the anatomy. This choice is currently based on manual geometric measurements performed on the preoperative scanner using conventional image processing software. The morphological result of the implantation of the endoprosthesis in the aorta is obtained by a CT scan carried out postoperatively. This scanner makes it possible to define the positioning of the endoprosthesis, the apposition surfaces between the aorta and the endoprosthesis and to predict the long-term result.
The goal of this clinical trial is to compare the efficacy of using polypropylene mesh for hernia prevention after stoma closure in patients with colorectal cancer and non-mesh repair. The main question it aims to answer is: can mesh help prevent hernia? Participants will be divided into 2 groups: with and without mesh using. They must be followed up for 2 years after enrollment in the study. Researchers will compare mesh and non-mesh groups to evaluate the benefits and harms of mesh using in hernia prevention.
The objective of this study will be to evaluate if photobiomodulation (FBM) can reduce postoperative pain in patients who will undergo endodontic surgery. For this randomized, controlled and double-blind clinical study, 34 patients without comorbidities who need endodontic surgery in the upper jaw (15 to 25 teeth) will be recruited. They will be randomly divided into an experimental group (n = 17) photobiomodulation (808nm, 100 mW, and 4J/cm2 with 5 points per vestibular). Applications will be made in the immediate postoperative period and 24 hours after surgery. Control group (n = 17) a FBM simulation will be performed in the same way as in the experimental group. In this group, the required analgesia will be administered within the standard with ibuprofen. Both groups will perform the necessary conventional procedures considered the gold standard in the literature. Both the patient and the evaluator will be blinded to the intervention performed. The primary outcome variable of the study will be postoperative pain, which will be assessed using the visual analog scale at all postoperative control visits (baseline, 24 hours and 7 days). As for the secondary outcome variables, the amount of systemic medication received according to the patient's need (will be provided by the investigator).. Radiographic images will be obtained after 1 and 2 months for evaluation of the repair (dimensions of the lesion, radiopacity). These radiographs will be taken digitally with the positioners implemented. Edema, ecchymosis, and evaluation of soft tissues in the anterior portion of the intra and extra-oral maxilla will also be evaluated. In addition, a digital thermometer. These parameters will be evaluated 24 hours and 7 days after the intervention. The X-rays will be taken in the 1st and 3rd month respectively.
In 2% to 3% infertility women, myoma is the only factor relevant to their infertility. However, the effects of intramural myoma on fertility are controversial. For infertile women with intramural myoma (types IV, V, VI of FIGO system) of 4 to 6 cm diameter, it is not clear whether myomectomy could improve pregnancy outcomes, especially in women undergoing ART. Besides, rigorous clinical research is needed to explore the changes and relevant biomarkers of endometrial receptivity through multi-omics study in patients undergoing myomectomy and ART treatment. Method Intervention and follow-up: (1) For the control group, evaluation protocols such as salpingography and/or laparoscopic tubal fluxation should be implemented to identify disorders such as hydrosalpinx. (2) Imaging evaluation: all pelvic MRI were performed. Other options such as transvaginal ultrasound are not excluded, but won't replace MRI. Enhanced MRI or DWI may be considered, but are not always required. (3) Surgical intervention: laparoscopic myomectomy is preferred, and abdominal myomectomy is also acceptable. (4) IVF treatment: the IVF regimen should include detailed records of the downregulation plan, number of cycles, frozen or fresh blastocysts. Study endpoints (1) Primary study endpoint: Live birth rate after IVF. (2) Secondary study endpoints: Clinical pregnancy rate after IVF; Cumulative pregnancy rate after IVF; Biochemical pregnancy rate after IVF; Sustained pregnancy rate after IVF (≥20 weeks); Miscarriage rate after IVF; Cycles of IVF; Pregnancy-related complications; Perinatal maternal and neonatal complications. (3) Exploratory endpoints: The correlation between imaging index and assisted reproductive outcomes, including endometrial thickness, uterine volume, type of endometrial echo, uterine contraction; endometrial vascular index (VI), flow index (FI), tubular flow index (VFI); uterine artery pulsation index (PI), uterine artery resistance index (RI), systolic/diastolic blood pressure of uterine artery (S/D). The correlation between endometrial receptivity and assisted reproductive outcomes is analyzed based on transcriptomics, metabolomics, methylation and proteomics in samples from peripheral blood, endometrial biopsy, endometrial exfoliated cells, cervical exfoliated cells and myoma.
This study is being performed to compare different methods of visualization during routine gum surgery. The gum surgery is standard of care. This study will compare the use of a small camera (videoscope) in conjunction with magnification glasses during surgery vs. surgery only using magnification glasses. Both methods are routinely used and are standard of care methods of visualization. The small camera (videoscope) is a device which allows us to see the area under high magnification and projects live video feed on a computer screen. The study is a split-mouth design pilot study. The patients are only receiving treatment that was previously diagnosed prior to entering the study. The treatment performed is standard treatment that fits in the routine standard of care. No interventional treatment is being performed. The only difference is the method of visualization/observation by the practitioner used during the surgical procedure. One side of the mouth will be treated with just loupes while the other side of the mouth will be treated with loupes and the videoscope.
In postoperative cardiac surgery under extracorporeal circulation, the patient may develop a vasoplegic syndrome, characterized by arterial hypotension (mean arterial pressure (MAP) < 65 mmHg); a decrease in vascular resistance and a cardiac output that may be normal or increased, and increased postoperative mortality/ International recommendations recommend the prescription of noradrenaline as a first-line treatment to reduce morbidity and mortality. However, excess norepinephrine or duration of exposure is also deleterious. The Acumen IQ device (Edwards Lifesciences) allows the calculation of a predictive index of arterial hypotension episodes (predictive hypotension index, HPI). HPI could improve norepinephrine weaning by preventing episodes of arterial hypotension or detecting preload dependence, thus avoiding the transient increase in norepinephrine during hypotension. This is a single-center, prospective, open-label, randomized, controlled, 2-group, parallel, intention-to-treat study. The aim was to evaluate the superiority of a new decision algorithm, based on the HPI delivered by the Acumen IQ device, to reduce the duration of norepinephrine administration in post-cardiac surgery vasoplegic shock. The duration of the interventional protocol is 72 hours. To evaluate the clinical impact of the protocol, the time of the study will be 30 days. Several follow-up visits will be performed (end-of-protocol day, discharge day, and at D30 of inclusion) to collect clinical, biological, and HPI monitoring data.
Comparing the growth of intra-operative tissue cultures of Cutibacterium Acnes after primary shoulder replacement when using a no-prep control group versus antimicrobial wound gel versus betadine applied to the skin layer after the skin incision has been made. Reducing the bacteria present in the deep tissues at the end of the surgery may prevent infections from developing in the future.
The goal of this multicenter observational study is to collect data prospectively of patients with pelvic organ prolapse undergoing ventral mesh rectopexy (as well as rectoceles, entero-/sigmoidoceles/ intussusception/ rectal prolapse or combined) by laparoscopy or robotic surgery and to evaluate the longterm functional outcomes. Secondly complications (mesh erosions, recurrence, reoperations) are evaluated. Following main questions will be analysed - other can follow in consultation with the collaborative 1. Is VMR the technique of choice for treatment of rectoceles? Functional results - recurrence - mesh related complications 2. Has a perineal descent an impact on the functional outcome of ventral mesh rectopexy perfored for external rectal prolaps, internal rectal prolaps, rectocele, enterocele, sigmoidcele or combined pelvic organ prolapse?
Aim: This randomized controlled trial study aimed to evaluate the effect of SMS use on compliance with postoperative breathing and coughing exercises and patient satisfaction in patients undergoing pulmonary lobectomy for lung cancer surgery. Material and methods: In the study, 62 patients who underwent lobectomy in a university hospital's thoracic surgery clinic between 01.02.2022 and 03.04.2023. The intervention group was chosen to be the group that received SMS messages.
In recent years, the world of anesthesiology is questioning one of its great dogmas: Are so many hours of strict fasting necessary in patients who are candidates for elective surgeries? The main objective of our clinical trial will be demonstrate whether preoperative oral loading with hydrocarbonate beverages reduces the time of return of intestinal function in the postoperative period compared to water administration and strict fasting in patients undergoing elective radical cystectomy.
