Filter by:A perianal fistula is an abnormal passageway that develops between the rectum and the skin near the anus. The fistula is considered complex if it branches into several openings or an abscess is also present. The main aim of this study is to learn if complex perianal fistulas in children and teenagers close after treatment with darvadstrocel. 2 to 3 weeks before treatment with darvadstrocel, each participant will have surgery to clean the fistula and to drain any abscesses. On the day of treatment, each participant will have the fistula cleaned and will receive an injection of darvadstrocel near the fistula, under anesthetic. For up to 1 year after treatment, participants will regularly visit the clinic for follow-up. The fistula will be examined and any side effects from the treatment will be recorded. Participants will have an MRI at one clinic visit (about 24 weeks after treatment).
The subjects were divided into two groups. Each group comprised 30 children. Children were randomly allocated in two groups via computer generated tables. Children in group-A underwent single dartos tubularized incised plate urethroplasty while those in group-B underwent double dartos tubularized incised plate urethroplasty.
For patients with End Stage Renal Failure (ESRF), the surgical creation of an Autogenous Arteriovenous Fistula (AVF) or Autogenous Arteriovenous Graft (AVG) is the recognised standard for providing vascular access. A functioning dialysis vascular access is essential to facilitate hemodialysis (HD) treatment. Advantages include improved hemodialysis initiation time, improved dialysis quality, better maintenance of accesses and generally, better outcomes in patients. Unfortunately almost 50% of AVF and AVG fail after a median lifetime of 3 to 7 years and 12 to 18 months respectively. Vascular access dysfunction is a major cause of morbidity and hospitalisation for ESRF patients, costing the healthcare system USD 18 million globally. Venous stenosis and scarring are caused by trauma from surgical access creation when the circuit comes arterialized and from repeated percutaneous punctures from subsequent hemodialysis. This study is performed to evaluate Sirolimus-coated balloon efficacy and safety using MagicTouch™ Drug coated balloon catheter (Concept Medical Inc, Tampa, FL, US) on AVF patency with de novo and recurrent stenosis.
In patients with vesicovaginal fistula, transvesical and extravesical repair will be compared in terms of operative time, complications and recurrence rates.
Gastrointestinal (GI) fistula is a complex condition with high mortality and requiring a multidisciplinary management. The aim of this study is to exploit the regenerative-tissue capacities of autologous emulsified adipose tissue-derived stromal vascular fraction (tSVFem, widely used in other medical fields - like plastic surgery -for different purposes) harvested and delivered locally by endoscopy to close the GI fistula. The proposed technique for the treatment of GI fistulas with tSVFem requires a minimal, inexpensive, easily reproducible mechanical manipulation of autologous adipose tissue without necessity of any enzymatic digestion or cell expansion.
The objective of our study is to identify the factors influencing the occurrence of a biliary leak after performing surgery leading to the creation of a biliary anastomosis to any segment of the digestive tract.
This is a prospective interventional study on the treatment of transsphincteric fistula in ano. After abdominal or thigh liposuction, fat was injected around the fistula tract that was then transected percutaneously with a sharp cannula and fat injected between and around the cut parts. The internal opening was closed with a suture. Minimum follow up of 12 months is planed
Prostate cancer is the first cancer amongst men with more than 50000 cases per year in France. Surgical, radiation, frost, or ultrasound induced rectourethral fistula is a rare complication (<1%) of localized prostatic cancer treatment but hard to manage. Different types of treatment exist: conservatory, trans-sphinteric (York-Masson), transanal, perineal, with or without muscle flap interposition. Gracilis flap interposition for rectourethral fistula management is a promising technique but few cases are described and functional results are scarce. The aim of this study is to present surgical and functional outcomes of rectourethral fistulas surgery with gracilis flap interposition after treatment of localized prostate cancer.
The mean of this study is to compare primary and secondary closure of tracheo-cutaneous fistulas and evaluate the differences in outcomes between both techniques.
A prospective, single-arm, multi-center post-market surveillance study of the BD® WavelinQ™ EndoAVF System for the Creation of Arteriovenous (AV) Fistula in Patients Requiring Dialysis.
