Filter by:The prognostic value of external vs internal pancreatic duct stents after pancreaticoduodenectomy remains controversial. This study aimed to evaluate the benefits of external and internal stents using the Updated Alternative Fistula Risk Score in both high-risk and low-risk patients with regard to the incidence of clinically relevant postoperative pancreatic fistula.
Crohn's disease (CD) is a life-long chronic inflammatory bowel disease (IBD) that may affect any site of the gastrointestinal tract, most frequently the ileum and colon. It is characterized by transmural inflammation and it can lead to strictures, due to activation of reparation of inflamed tissues and consequent fibrosis, or penetrating lesions, such as fistulas, between two different intestinal tracts or between intestine and surrounding organs. Fistula occurrence can lead to formation of abdominal or pelvic abscesses. Such complications cause intestinal damage and usually require surgery, leading to disability, impairment of patients' quality of life, with significant impact on direct and indirect health-care costs
The aim of this randomized controlled study is to compare the efficacy of biodegradable internal pancreatic stenting versus no stenting in patients undergoing pancreatoduodenectomy (PD), focusing on a possible superiority association of the device in preventing clinically relevant postoperative pancreatic fistula (CR-POPF). Patients undergoing PD will be randomized into two arms: - arm 1: a biodegradable internal pancreatic stent will be placed at the level of the pancreatic anastomosis - arm 2: no pancreatic stent will be placed at the level of the pancreatic anastomosis The rate of occurrence of CR-POPF will be compared between the two arms.
To confirm the time point of CR-POPF of grade-B that patients with biochemical leak after PD or LPD turned into.
In this prospective, randomized trail, duration of non-cutting seton placement in patients with fistula-in-ano is evaluated.
The goal of this clinical trial is to assesses the safety of autologous RD2 Ver.02 as compared to a control for managing transsphincteric and intersphinsteric anal fistulas. The main questions it aims to answer are: Assess the safety and efficacy of RD2 Ver.02 in anal fistula application, compared to control. Complication rate by 6 months of anal fistula treatment with RD2 Ver.02 compared to control. Recurrence of anal fistula at 12 months post-treatment Incidence of perirectal infection by 6 months in anal fistulas treated with RD2 Ver.02 compared to control. Patients will be randomized in to 2 arms. For all patients, blood will be drawn to ensure the blinding of the patients, the fistula will be evaluated and debrided, and then the internal fistula opening will be suture-closed, and a water leak test will be performed to ensure sealing. Following the water leak test, In the treatment arm, the patient's own coagulating blood will be applied into the entire fistula tract, allowing it to clot and serve as a provisional matrix inside the fistula tract. In the control arm, the blood sample will be discarded and saline will be applied to the fistula tract.
The FIBROPANC-1 investigates the feasibility and safety of preoperative stereotactic radiotherapy of 4cm pancreas in patients undergoing pancreatoduodenectomy at high risk (>25%) of developing post operative pancreatic fistula (POPF). A single course of 12Gy preoperative radiotherapy may lead to sufficient fibrosis in a small (4cm) targeted area, thereby reducing the risk of grade B and C POPF.
The purpose of this open, multicenter pilot trial is to evaluate the tolerance of the combination of a gel and a plug made of Wharton's jelly in the treatment of ano-perineal fistulas resistant to surgical treatment.
Prospective, observational study evaluating the clinical use and outcomes of the FLEX Vessel Prep (VP) system in arteriovenous fistulae or grafts presenting with clinical or hemodynamic abnormalities following 12 months post treatment.
The arteriovenous fistula (AVF) is the reference hemodialysis vascular access for both adult and pediatric patients. The cannulation quality is decisive for the quality of the dialysis. Difficult AVF cannulations are more frequent in pediatrics than in adults. Recent studies in adults have shown that ultrasound-guided AVF cannulation improves the cannulation quality and therefore the quality of dialysis. This study aims to prove that ultrasound-guided AVF cannulation in children will improve the quality of dialysis overall.
