Filter by:Rationale: Perianal fistulas are a common incapacitating problem. Many patients are treated by seton drainage to prevent recurrent abscess formation. Nowadays, vessel loops or sutures are used for drainage. The knot of these seton drains can cause complaints of pain or tenderness if it presses against the external opening of the fistula or even slides in to the fistula tract. Medishield B.V. designed a knotless seton drain, the SuperSeton. This could decrease the pain complaints caused by the knot. Objective: The aim of this study is to determine the feasibility of SuperSeton placement in patients with perianal fistulas. Study design: The design of the study is a feasibility study. Study population: Patients (≥ 18 years) with perianal fistulas (ever) treated with a knotted seton are eligible. Intervention: The SuperSeton will be placed at the outpatient clinic in patients that already have a seton in situ. This seton will then be exchanged by the SuperSeton. In case patients do not have a seton in situ, the SuperSeton can be placed at the operating theatre in day care setting instead of a regular seton. Main study parameters/endpoints: The primary outcome is seton failure (loosening of the seton). Secondary outcomes are time of procedure, complications and quality of life measured by the PDAI ('Perianal Disease Activity Index'). Nature and extent of the burden and risks associated with participation: The SuperSeton will be placed in patients with perianal fistulas (ever) treated with a conventional knotted seton. There are no additional risks involved. The seton will be placed at the outpatient clinic in patients with a seton in situ, or at the operating theatre in day care setting in patients with a perianal abscess without a seton. The material that is used for the Setons is of medical grade polyurethane, this is the same material of catheters that are already used in clinical practice (instech BTPU 027). The Setons including the insert (BTPU) are supplied sterile (Synergy Health). Sample size calculation: A group of 60 patients will be included to determine feasibility of the SuperSeton. The proposed treatment protocol is considered feasible if at least 70% of the SuperSetons stay in place.
A new strategy for treatment of late radiation damage is to develop methods aimed at stimulating the regenerative capabilities of irradiated tissues. Since the main pathogenetic mechanism of the development of late radiation damage is the death or damage of the replicative mechanism of stromal cells (SC), a justified approach can be considered as transplantation of intact SC. Currently, there is convincing evidence in the scientific literature that the injection of intact autologous SCs into the zone of fibrosis surrounding the chronic radiation ulcer leads to the healing of a wound defect. An Initiative Clinical Trial. Introduction of autologous regenerative cells of adipose tissue for the treatment of post-irradiation vaginal-rectal fistula. It is assumed that patients will be included in the project within 12 months; the monitoring of each patient will last for 6 months; the total duration of the clinical part of the study will be 18 months; The total duration of the clinical trial including the preparatory phase and the writing of the report is about 24 months. It is assumed that at least 16 patients aged 20 to 75 years who have verified diagnosis of post-irradiation vaginal-rectal fistula will participate in this pilot project. The aims of the clinical trial are to preliminarily assess the safety, effectiveness and quality of life of patients after introducing autologous regenerative cells of adipose tissue for the treatment of post-irradiation vaginal-rectal fistula.
This randomized trial aimed to compare conventional draining seton with or without rerouting of the fistula track in treatment of complex anal fistula
Anastomotic leakage of the pancreatojejunostomy is often discovered with considerable delay, causing severe peritonitis, hemorrhage due to erosion of vessels, sepsis, and death. Microdialysis catheters can detect focal inflammation and ischemia, and has a potential for early detection of anastomotic leakage. This observational study will examine if monitoring with microdialysis catheters can detect anastomotic leakage after pancreaticoduodenectomy earlier than current standard of care.
Patients with simple anal fistula will undergo fistulotomy operation and will be divided into two groups: the first will undergo marsupialization of the laid open fistula track and second group will not undergo marsupialization. The effect of marsupialization on healing of anal fistula will be compared postoperatively.
The study aims to evaluate safety, feasibility and effectiveness of local injections of autologous and micro-fragmented adipose tissue obtained with the Lipogems® system in patients with refractory complex fistulizing perianal Crohn's disease.
Many older adults require hemodialysis for advanced chronic kidney disease, but it is not clear which permanent vascular access method (fistula or graft) is best with respect to access effectiveness and patient satisfaction. In this pilot study, the study team will test the hypothesis that older adults undergoing graft access placement will more effectively transition from catheter-based to arteriovenous access-based hemodialysis; have fewer following vascular access procedures; have better upper extremity function; have better self-sufficiency with daily activities; and better health-related quality of life compared to those who undergo arteriovenous fistula access placement. The study will establish feasibility of randomizing older adults to the two types of arteriovenous access surgeries; evaluate relationships between measurements of pre-operative physical function and vascular access development; compare vascular access outcomes between the two groups; and gather longitudinal assessments of upper extremity muscle strength, performance of activities of daily living, and patients' reports of satisfaction with their vascular access and quality of life.
Colovesical fistulas are well-recognized but relatively uncommon pathology to both the general and colorectal surgeon. It is a complication arising from an underlying primary acute to chronic inflammatory process. Although colovesical fistulas are uncommon, they are associated with significant morbidity, affect quality of life, and may lead to death, usually secondary to urosepsis. Early diagnosis and management is essential. The purpose of the study is to determine the objective use of cystographic evaluation on postoperative day two to guide early Foley catheter removal post colovesical fistula takedown. The hypothesis is that a cystogram showing no extravasation of contrast on postoperative day two will predict safe removal without increased morbidity. This is an uncontrolled, single arm trial. Patients who meet criteria to undergo either minimally invasive or open colovesical fistula takedown with sigmoid colectomy, without evidence of the need for bladder repair will be eligible to participate. An indwelling Foley catheter is placed intraoperative and continued postoperative. All patients who consent to participate would undergo a cystogram on postoperative day two. The cystogram will be conducted by a radiologist and technician well-trained in the techniques and interpretation of the study. The colorectal surgery enhanced recovery protocol will be followed on all patients with the exception of the cystogram being conducted on post-op day two. If there is no evidence of extravasation of dye is seen on the cystogram the Foley catheter will be removed. Patients will be monitored closely following catheter removal to ensure self-diuresis.
The aim of the present prospective study was, first, to verify the correlation between biliary colonization and postoperative infectious complications, and secondarily to asses morbidity and mortality for patients who underwent pancreaticoduodenectomy. The hypothesis is that a proportion of post-operative infections after pancreaticoduodenectomy is due to bacteria that colonize the bile ducts during the preoperative period.
The purpose of this study is assessment of safety, efficacy, and short-term outcome of SQUID™ in the embolization of Dural Arteriovenous Fistula
