Active clinical trials for "Fistula"

End stage renal failure (ESRF)describes an irreversible loss in renal function. The majority of these patients will opt for haemodialysis (HD)as their chosen method of renal replacement therapy (RRT). Arteriovenous fistulae (AVF) are the optimal method of achieving vascular access to permit HD. AVF are created with a small surgical procdure to join the artery and vein together. Over the next 6- 8weeks after surgery the AVF should grow ("mature") into a vessel suitable for needles to be inserted for dialysis. Unfortunately however, around 24% - 35% of AVF fail at an early stage. Some anaesthetic techniques can influence intraoperative blood flow and venous diameter, factors which are associated with fistula success. There remains no conclusive evidence that any particular anaesthetic technique can significantly influence long term surgical outcome. This study aims to investigate whether a regional, compared to local, anaesthetic technique can affect fistula patency.

Postoperative pancreatic fistula (POPF) and other surgical complications are common after pancreatoduodenectomy (PD) and POPF is a major complication. The drainage of pancreatic duct is important and a stent is usually placed in the operation, but it is still controversial whether the stent drainage is internal or external.

Anal fistulae are a difficult problem to treat. The optimal treatment for fistula involving the anal sphincter is unclear. Two standardly used methods of treatment are the ligation of intersphincteric fistula track (LIFT) procedure and the use of an anal fistula plug. The purpose of this study is to exam the rate of fistula closure between the LIFT procedure and the use of a fistula plug

Several systematic reviews have investigated the management of the pancreatic stump in order to reduce the postoperative pancreatic fistula (POPF) rate after distal pancreatectomy (DP). The appropriate closure technique of the pancreatic stump is still debated. There is no published experience about the comparison of the Endo GIA Reinforced Reload with Tri-Staple Technology (TS) versus Harmonic Focus (US) after distal pancreatectomy (DP) regarding the reduction of POPF. The investigators want to compare the incidence of clinically-relevant POPF (CR-POPF) after DP, depending upon the transection technique (TS versus US). This is a randomized controlled, multicenter, patient-blinded, superiority trial. This protocol was designed according to the SPIRIT guidelines. Two groups of 76 patients (152 in total) with an indication for elective minimally invasive or open DP for a lesion of the body-tail of the pancreas. The two techniques analyzed are Endo GIA Reinforced Reload with Tri-Staple Technology (TS) and Harmonic Focus (US) as control. The primary endpoint is to evaluate the incidence of CR-POPF rate after DP. Secondary endpoints are intraoperative outcomes (blood loss, operative time and conversion of the minimally invasive procedure), postoperative outcomes (complications rate; hospitalization parameters to 90 days; mortality) and treatment costs.

This is a randomized, controlled, parallel study to compare the results of treatment for patients with transsphincteric fistulas-in-ano.

Paclitaxel is an antiproliferative drug that can limit vascular intimal hyperplasia. Paclitaxel-coated balloons already have indications in the treatment of peripheral arterial disease. This randomized controlled trial is designed to prove the superiority of a drug-eluting balloon catheter (Paclitaxel-coated balloon) over a plain balloon catheter in the treatment of stenosed autogeneous and prosthetic vascular accesses, in hemodialysis patients. The hypothesis is that use of drug-eluting balloon will improve post-interventional patency of the access, and therefore, limit numbers and days of hospitalization for maintenance of hemodialysis vascular accesses.

Will the technique of adding lidocaine to bupivacaine fasten the onset of bupivacaine alone for infraclavicular brachial plexus block in end-stage renal disease (ESRD) patient?

To show that prevalence of inflammation of the small bowel in patients with anorectal disease is under-diagnosed based on colonoscopy ileoscopy alone.

The primary aim is to test the magnitude and duration of analgesia provided by single dose multi-drug analgesia administered for perianal block, and compare with standard solution (Marcaine & Lidocaine in 1:1 mixture - Total 60 ml), at post-operative period and also to compare with the standard solution including their respective post-operative opioid or non-opioid oral analgesic requirement. Local anesthesia via a perianal block using multi-drug analgesia or standard solution will be compared using the Numeric pain rating scale on Post-operative day 1, 3 and during follow up visit on day 7. The investigators hope to find a better control of post-operative analgesia which will lead to better functional outcomes. Possible decrease consumption of opioids in the post-operative period will perhaps decrease the cost and chances of addiction and will increase patient comfort and compliance.

This study hopes to determine if a negative pressure dressing is superior to a traditional dressing for speeding fistula closure after laparotomy. This study has a broad variety of implications. Patient safety is a paramount concern: Investigators hope to identify a superior method of wound management which minimizes risk for skin breakdown, sepsis, and morbidity. In addition, patient satisfaction would be improved with a method for faster wound healing. Finally,implications exist in the realm of a cost-benefit analysis, for example, although the VAC method is more costly, it may save money if it speeds healing and prevents the need for reoperation. Alternatively, if the VAC method is not shown to be beneficial, physicians can avoid using a more costly device with no proven benefit.
