5 Clinical Trials for Various Conditions
This study aims to assess the efficacy and rate of stent migration in standard of care esophageal stents that are not fixed, compared to those that are fixed with either standard of care OTSC stentfix or standard of care stent placement with suturing in both benign and malignant esophageal strictures.
Esophageal stents are commonly used for benign esophageal pathology, especially strictures or esophageal mucosal defects such as leaks, fistulae, or perforations. The major limiting factor to stent placement is the high migration rate of the stent. Investigators are trying to prospectively evaluate the efficacy of endostitch in preventing stent migration in benign esophageal disease in comparison with standard, fully covered self-expanding metal stents (FCSEMS) placement without fixation.
The goal of this observational study is to learn about the long-term results of glaucoma stent surgery in men and women 18 or older who have had cataract and microstent surgery in the past 2 years at the Moran Eye Center. The main questions the study aims to answer are: 1. How often are microstents mispositioned? 2. What effect does microstent positioning have on intraocular pressure after surgery? Participants will have a one-time clinic visit for an eye exam and Optical Coherence Tomography (OCT) . From the eye exam and OCT, Researchers will assess and categorize the position of the microstents and assess the Schlemm's canal dilation. Researchers will review the participants' medical records to acquire 2-year data for the following: 1. Surgeon type and level of experience (resident, fellow, attending ophthalmologist) 2. Proportions of proper gonioscopic placement intraoperatively for each surgeon group 3. Effectiveness of surgery, based on change in intraocular pressure (IOP) from baseline medicated IOP, number of IOP-lowering medications the patient was able to discontinue, and rate of need for additional glaucoma surgery.
Researchers are trying to determine which suturing pattern for esophageal stent placement is more effective in a randomized fashion as currently what suturing pattern to use is an arbitrary decision.
No standard approach currently exists for endoscopic esophageal stent placement, and both sutured and un-sutured techniques are employed for esophageal stent placement currently. The primary purpose of this study is to find out if suture fixation of esophageal stents is superior to non-suture fixated stent placement. Consecutive patients who are scheduled for esophageal stent placement will be identified as potential study participants by study personnel and will be approached on the day of the procedure. Informed consent will be obtained and patients will be randomized into suture fixation and non-suture fixation groups. Patients in the suture fixation group will have their esophageal stent secured in location with two endoscopic sutures. Those in the non-suture fixation group will have no sutures placed. Main study outcome is stent migration, and rates of stent migration will be compared in the two groups.
