Filter by:Cannulation of complex arteriovenous fistula (AVF) or graft (AVG) is a challenge to renal nurses. Ultrasound (US) guidance on central and peripheral venous access visualisation has been widely adopted in nephrology and shown to reduce complications of vascular interventions. With broader adoption of handheld US devices in clinical services, renal nurses could acquire this point-of-care technique to increase the successful cannulation rate while facilitating confidence build-up during training and practice. We aim to evaluate the use of handheld US on difficult AVF/AVG cannulation in a hospital-based dialysis unit.
OSSM-001 will be evaluated in a double blind, randomized phase I safety study of a single injection of 100 and 300 million bone marrow derived MSCs in 16 patients with refractory perianal fistulas in the setting of Crohn's disease. There will be 2 cohorts (100M and 300M MSCs); 8 subjects in each cohort; 6 subjects receiving the investigational product and 2 subjects receiving placebo (normal saline) in each cohort.
The aim of this study is to compare the clinical results of combining a pedicle connective palatal flap with a trapezoid buccal flap with the standard buccal flap alone in the closure of oro-antral fistula (OAF), and the buccal flap combined with leukocyte and platelet rich fibrin.
Postoperative pancreatic fistula is one of the most serious complications after gastric cancer surgery and can lead to surgery-related death. Postoperative pancreatic fistula for gastric cancer often occurs in accidental injury of pancreas during peripancreatic lymph node dissection, blunt separation of pancreatic capsule injury, laparoscopic instrument clamp and long-term compression of pancreas, etc. TissePatchTM is a synthetic, self-adhesive, absorbable surgical sealant and barrier used to seal and reinforce wounds and prevent leakage of air, blood, and fluid during neurosurgery, spine, chest, and soft tissue surgery. Therefore, we proposed whether the use of TissuePatchTM can reduce the occurrence of pancreatic fistula after gastric cancer surgery, and the clinical trial of the effectiveness of TissuePatchTM on the prevention of pancreatic fistula after radical gastrectomy of gastric cancer can provide new clinical data for the prevention of pancreatic fistula after gastric cancer surgery, and help reduce a series of adverse reactions caused by pancreatic fistula in patients.

Design: this study includes two separate groups of cases and controls each consisting of 40 participants randomly allocated for the phase 2 of clinical trial. Settings and conduct: Patients with complex perianal fistula referred to Imam Khomeini hospital, will be included in the study if they contain inclusion criteria. The fistula was evaluated by clinical examination and MRI and patients fill the quality of life questionnaire. Exosome injections are performed weekly for consecutive three weeks. Patients will reexamined and fill the questionnaire and MRI will done 12 weeks later. Recent findings will compare with the initial data. During this period, patients are examine for complications. Main outcome variables: Discharge amount; External orifice re-epithelialization ; Inflammation, discharge and abscess larger than 2 cm in MR imaging; Quality of life questionnaire score, Inflammatory markers such as CRP, IL-6, TNF-a, calprotectin
The cannulation of arteriovenous fistula is a painful procedure in hemodialysis patients. Previous studies have shown the effectiveness of virtual reality in reducing pain during needle-related procedures
Randomised Controlled Trial comparing Laser assisted closure of transsphincteric fistula to the rectal advancement flap.
Postoperative pancreatic fistula (POPF) is one of the most frequent and ominous complications after PD, and its occurrence reportedly ranges from 2-40 %. Severe POPF prolongs hospital stay and requires the use of specific treatments, such as the use of antibiotics, nutritional support, endoscopy, interventional radiology, and/or reoperation, etc.. Several anastomotic surgical techniques have been developed to reduce the incidence of pancreatic fistula in recent decades, including the duct-to-mucosa method, pancreaticogastrostomy, Peng's binding method, and the "end-to-end" or "end-to-side" invaginated method. Among these techniques, the conventional duct-to-mucosa method remains the most popular anastomosis due to its advantages. The size of the pancreatic remnant is not limited; moreover, the jejunal lumen and pancreatic remnant lead to easier anastomosis . Compared with two-layer duct-to-mucosa anastomosis, the novel one-layer duct-to-mucosa PJ anastomosis method has been reported to be efficient at reducing POPF occurrence. However, the two cited retrospective studies might lead to selection bias. Because this evidence is insufficient, we will conduct a randomized controlled trial to verify the superiority of one-layer duct-to-mucosa PJ anastomosis after PD over the two-layer technique.
Rationale: Perianal fistula is a burdening disease with an annual prevalence of 2/100.000 in the Dutch population. More than 90% of crypto-glandular fistulas originate from anorectal abscess. Despite adequate drainage of anorectal abscess up to 83% recurs or results in an anal fistula, the majority developing within 12 months. Up till now it is not common practice to routinely administer prophylactic antibiotics to prevent anal fistula development.\ Objective: The objective of this trial is to establish if adding antibiotic treatment to surgical drainage of perianal abscess results in less perianal fistulas. Study design: The study concerns a double-blind, placebo-controlled, randomized, multicenter trial with treatment of perianal abscess by surgical drainage alone or combined with antibiotic treatment. Patients will be accrued by all participating clinics. The design involves allocation of all appropriate consecutive patients with a primary occurrence of perianal abscess to surgical drainage followed by either antibiotics or placebo. Data will be analyzed on 'intention to treat' basis in case patients are not subjected to the randomized treatment modality. Study population: Men and women of 18 years and older who present for the first time with a perianal abscess. Intervention (if applicable): The antibiotic group receives 7 days of oral metronidazole (500 mg every eight hours) and ciprofloxacin (500 mg every twelve hours) in addition to surgical drainage. The other group receives surgical drainage and postoperatively identical placebo tablets. Main study parameters/endpoints: Primary outcome measure is development of a perianal fistula. Secondary outcome measures are quality of life at 12 months measured with the EQ-5D-5L with Dutch rating. Further: in-hospital direct and indirect costs and out-of hospital postoperative costs, need of repeated drainage, patient related outcome (PRO) and clinical outcome measures. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: For this study, patients are asked to take part in a study comparing the addition of antibiotic treatment to surgical drainage of perianal abscess. Patients will not be burdened by extra hospital visits. At baseline participants will complete PRO questionnaires. Also at 1 week and 3, 6 and 12 months participants will fulfill the PRO questionnaires. These will be send to them by email and will take approximately 10 minutes each time.
