Filter by:The aim of this study was to reduce the incidence of postoperative pancreatic fistula after pancreaticoduodenectomy by using different pancreaticojejunostomy methods according to the position of the pancreatic duct.
This study is a prospective, randomized, controlled trial. In this study, 30 patients who underwent endotracheal tumor resection under rigid bronchoscope or stent placement for acquired tracheoesophageal fistula were selected as the subjects. The patients were randomly divided into remazolam general anesthesia group (R group) and propofol general anesthesia control group (P group). Remazolam general anesthesia group (R group): Remazolam 0.4 mg/kg, oxycodone 0.2 mg/kg and rocuronium 0.9 mg/kg were given for anesthesia induction. Propofol general anesthesia control group (P group): Propofol 1.5mg/kg, oxycodone 0.2mg/kg and rocuronium 0.9mg/kg were given for induction of anesthesia. After induction, high-frequency jet ventilation was used in both groups, the respiratory rate was 30-60 times/min, the inspiratory-to-breath ratio was 1:2, and the driving pressure was 0.8-1.0 KPa. Group R was given remazolam 1mg/kg/h and remifentanil 6-8ug/kg/h for maintenance. Group P was given propofol 4-8 mg/kg/h and remifentanil 6-8ug/kg/h for anesthesia maintenance. The dosage of propofol or remazolam was adjusted according to BIS and intraoperative hemodynamic changes. Rocuronium bromide 10 mg was added every half hour. Intraoperative application of vasoactive drugs to maintain mean arterial pressure above 60mmHg to avoid perioperative hypotension. Blood oxygen saturation and end-tidal carbon dioxide were monitored to avoid perioperative hypoxemia and hypercapnia, and warm measures were used to maintain the patient's intraoperative body temperature above 36.0°C. After surgery, group R was treated with sugammadex sodium 2-4 mg/kg to antagonize rocuronium bromide, and 0.5 mg of flumazenil was used to antagonize remazolam by intravenous injection; group P was treated with sugammadex 2-4 mg/kg to antagonize rocuronium.

Feasibility of the Vessel Restoration System for AVF
Palatal fistulas are a major burden to surgeons and patients in the management of cleft palate. Their high rate of occurrence and recurrence makes them particularly challenging even to the highly skilled surgeon. Prevention of postoperative palatal fistula is therefore of paramount importance. Closure of the nasal mucosa under tension has been proposed as a major cause of palatal fistula formation. However, depending on the presentation of the cleft palate, it may be impossible to achieve surgical closure with minimal tension. Till date, there is no universally acceptable method of preventing palatal fistula formation following cleft palate repair. And although the use of pre-surgical appliances such as Latham appliance and the use of local and distant tissues to achieve two layer closure have been proposed, the use of a superpositional collagen graft may also be used to achieve closure of the nasal mucosa with minimal or no tension during cleft palate repair. Collagen grafts have the added advantage of being more patient friendly compared to the Latham appliance which requires an initial surgery for appliance insertion before surgical cleft palate repair. They are also less technique sensitive compared to the use of local and distant tissues. The investigators therefore aim to provide high level scientific evidence of the effectiveness of collagen graft in the prevention of postoperative palatal fistula.
The investigators propose a clinical trial and nested qualitative study to 1) quantify the effectiveness of an insertable vaginal cup to manage fistula urinary incontinence, 2) examine user and implementer acceptability, and 3) quantify fistula management cost. Two intervention models will be compared among women awaiting fistula surgery or whose surgery was unsuccessful: 1) a vaginal cup ('cup'), and 2) the cup attached via rubber tubing to a leg-secured urine collection bag ('cup+') for greater urine holding capacity.
Following genital fistula repair, fistula repair breakdown and recurrence, persistent and incidence incontinence are major adverse outcomes, limiting women's health and wellbeing. Using a prospective design, the investigators seek to identify modifiable risk factors to establish key targets for intervention, followed by qualitative work to refine the feasibility and acceptability of potential intervention strategies.
The aim of this study was to assess the risk and complications after preoperative drainage of biliary obstruction in patients who underwent pancreatoduodenectomy. A retrospective cohort study of all patients who underwent pancreatoduodenectomy from January 1st, 2015 to September 30th, 2021. Patients who had preoperative bile duct drainage were compared to patients without intervention. Type of interventions, complications and outcome after surgery were compared using univariate and multivariate analysis.
The primary study objective is to evaluate the benefit of the Sirolimus eluting Collagen implant (SeCI; Sirogen), a single dose prophylactic treatment delivered intraoperatively at the time of surgical creation of an arteriovenous fistula for hemodialysis vascular access.
This is a single-center, prospective, single-arm clinical study to evaluate the feasibility, safety, and performance of VenoStent's SelfWrap® Bioabsorbable Perivascular Wrap on arteriovenous fistulas (AVFs). All participants are chronic kidney disease (CKD) patients already receiving hemodialysis treatments that are referred for creation of a new arteriovenous fistula (AVF).
