Filter by:This trial will investigate what surgical technique between pancreaticogastrostomy and pancreaticojejunostomy with transanastomotic externalized drains is associated with the lowest rate of pancreatic fistula after pancreaticoduodenectomy in case of high-risk pancreatic remnants.
This study is an extension to re-treat partial and non-responders from the previously approved Phase 1 MCS-AFP protocols IRB #12-009716 (Crohn's Disease perianal fistulas) and 15-003200 (cryptoglandular perianal fistulas).
This is a single arm investigator-initiated study designed to test the feasibility and potential efficacy of preoperative lanreotide to reduce the risk of postoperative abscess or pancreatic leak and fistula. All consenting patients undergoing planned elective pancreaticoduodenectomy or distal pancreatectomy for malignancy or suspected malignancy will be treated with a single deep subcutaneous dose of lanreotide prior to planned resection on the day of surgery. Following this intervention, care will be based on standard treatment protocols. Sixty-day mortality and morbidity will be collected for all patients.
The fact that still exist is which method for repairing of secondary cleft palatal fistula is the best. This study will have shown whether using of Acellular dermal Matrix decreased the fistula formation versus using Conchal Cartilage during secondary fistula. Among studies that published, they have not consensus for using acellular dermal matrix. Most of the questions are about cost effectiveness, time that surgery and rehabilitation need and patient risk ( risk of transmission disease from other human tissue )
This is a prospective observational study evaluating wound complications following head and neck surgery. Patients undergoing major head and neck surgery will be included in the study. Patients meeting eligibility criteria will be identified by members of the University of Michigan Head and Neck Oncology Division of the Department of Otolaryngology. The primary aim of this study is to identify risk factors for poor wound healing as well as biologic markers associated with wound related complications in head and neck surgery. Most specifically, this study evaluates the effects of thyroid hormone on wound healing. This study will also evaluate pre-operative labs and comorbidities as well as reconstructive factors, post-operative labs, and other variables associated with wound healing. All interventions regarding wound healing fall under current standards of care and standard practice. Data regarding post-operative wound complications will be collected in a prospective fashion on the variables under study using study-specific datasheets. Data sheet will be entered into a secure database for analysis.
Anal fistula treatment is associated with increasing risk of anal incontinence until 40% of cases. New and alternative treatments (glue, advancement flap, plug…) decrease this risk, but with fistula efficacy treatment in 40 to 60% of cases. Radiofrequency might destroy fistula tract without lesion of anal sphincter. Objective : Fistula healing rate and anal continence, 6 and 12 months after radiofrequency procedure. Methods : Clinical and MRI evaluation before, 6 and 12 months after treatment. Patients : 50 patients with low, high, complex and Crohn disease fistula. An intermediate analysis is expected after the first 20 patients, to verify morbidity. Evaluations : - Fistula clinical healing 6 and 12 months after procedure - Fistula MRI healing 12 months after procedure - Anal continence before and after procedure - Feasibility og radiofrequency procedure - Morbidity - Success and failure prognostics factors of this procedure
This is research in which students are queried by questionnaires on their satisfaction with and experience with certain educational practices (use of a camera image projecting during a live surgery) or with pre-recorded video. As data collection only involves survey data collection and satisfaction with an educational experience, and randomization/intervention is only involving use of one type of educational method versus another .
Peripheral regional anesthesia induces a sympathectomy-like effect with neurovascular changes causing increased arterial blood flow and venodilatation . Near-infrared spectroscopy (NIRS) can be applied to different kinds of tissue providing oxygen saturation by detecting the absorption and reflection of near-infrared light . The effect on peripheral tissue oxygenation in patients undergoing arteriovenous fistula revision has not yet been examined. We postulate an increase in tissue oxygenation by sympathicolysis caused by peripheral regional anesthesia that might be the reason for beneficial outcome. The aim of our study was to demonstrate the effect of a supraclavicular plexus block in this group of patients.
To evaluate the safety and efficacy of the IN.PACT™ AV Access Drug Coated Balloon (DCB) compared to percutaneous transluminal angioplasty (PTA) for treatment of subjects presenting with de novo or non-stented restenotic obstructive lesion of native arteriovenous dialysis fistulae (AVF) in the upper extremity.
The purpose of this study is to determine whether the use of drug-eluting balloons is effective in the treatment of (re)stenosis in dialysis fistulae.
