Active clinical trials for "Fistula"

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.

The primary objective of this double-blind study is to compare the frequency of primary patency at 6 months in patients with stenosis of arteriovenous fistula (AVF) treated either by conventional angioplasty + angioplasty with balloon impregnated with paclitaxel or by conventional angioplasty + angioplasty with placebo balloon (balloon not impregnated with paclitaxel). The other objectives of the study are: To compare the frequency of primary patency at 3 months and 12 months. To compare the rate of restenosis > 50% at the site of angioplasty at 3, 6 and 12 months. To compare, at 3, 6 and 12 months, the proportion of patients with arteriovenous fistula deteriorating back to preoperative flow rate (within 20% of preoperative flow rate). To compare, at 3, 6 and 12 months, the proportion of AVF with a flow rate < 500 ml / min. To compare, at 3, 6 and 12 months, the cumulative rate of thrombosis. To compare, at 3, 6 and 12 months, the medical costs related to direct medical care, initial treatments, monitoring, diagnosis and treatments of complications.

To determine whether pre-operative pancreatic stenting for distal pancreatectomy will impact the incidence of a post-operative pancreatic fistula, as defined by postoperative. If pre-operative pancreatic stenting appears to reduce the formation of Postoperative Pancreatic Fistula (POPF) in this pilot study, this will form the basis of a larger randomized trial in the future. The hypothesis is that pre-operative pancreatic duct stenting can significantly decrease the rate of development of a post-operative pancreatic fistula after distal pancreatectomy.

Infiltrations from cannulation difficulties result in significant morbidity including loss of vascular access (VA) loss in hemodialysis (HD). Cannulation is reliant on personnel skill and VA characteristics. Surface marking of VA lacks real-time information and traditional ultrasound (US) devices are large, expensive and require skilled operator expertise. Sonic Window© (Analogic Ultrasound, Peabody, MA) is a coronal mode ultrasound device (CMUD) approved for VA cannulation. Study is a single center randomized, prospective pilot study comparing handheld US-guided cannulation of new arteriovenous fistula (AVF) to standard cannulation practices.

The purpose of this study is to determine whether Teduglutide is safe and feasible to be given for the treatment of enterocutaneous fistula (ECF). The hypothesis is that the drug will be well tolerated and will improve the volume of daily ECF output as well as improve the functional quality of life.

Arteriovenous fistulas (AVFs) are the preferred type of vascular access for dialysis, but many of them fail to mature. The optimal timing of intervention to salvage immature AVFs is unknown.The study proposes a randomized clinical trial comparing the clinical and economic impact of early vs late angioplasty in non-maturing AVFs. The study proposes a RCT to test the hypothesis that, as compared to early angioplasty of non-maturing AVFs, late angioplasty results in a lower proportion of AVFs being used at 6 months, but a greater long-term AVF patency , lower requirement of subsequent interventions to maintain AVF patency for dialysis, and lower overall cost of access maintenance.

This randomized controlled trial (RCT) aims at assessing the influence of octreotide on pancreatic fistula or complications following pancreatoduodenectomy in patients with soft pancreas. Previously reported trials have included all types of pancreatic resections and have include all types of pancreas and have shown no clearcut benefit of octreotide after pancreaticoduodenectomy (PD). Soft pancreas and normal sized duct are the risk factors for fistula following PD. This study's focus is on this select group of patients and aims to assess the role of octreotide in patients with soft pancreas.

Anastomotic fistula following bariatric surgery are lifethreatening complication with a 37.5% mortality rate. All the modalities for bariatric surgery are involved in this type of complication, but Sleeve gastrectomy is the main surgery responsible for the frequency and the severity of the fistula. The management of this complication is still controversial and potentially lethal. The average number of endoscopic sessions was 4 (range 2-11). The closure could be obtained within a mean time of 88 days (range 6-216 days). Therefore endoscopic management has to be improved to reduce the duration of the treatment and the number of endoscopic sessions. OTSC clips could help to improve the endoscopic management because of a more prehensive, deeper and larger suture area.

This study comprises a prospective study of 40 patients with transphincteric anal fistula. The patients were classified into two groups: Group I: Fistulectomy, closure of internal sphincter and rectal advancement flap includes mucosa, submucosa, and circular muscle layer sutured 1cm below the level of internal opening. Group II: The same as group one but the flap includes only mucosa and submucosa.
