Seeded Cells on Matrix Plug Treating Crohn's Perianal Fistulas (STOMP-II)

Perianal FistulaCrohn's Disease

A Phase II study to assess the safety and efficacy of AVB-114 in treatment of complex Crohn's perianal fistulas in subjects with quiescent rectal disease and whose fistula has failed to respond to biologic or conventional therapy. Combined remission of treated perianal fistula in the investigational treatment arm will be compared to a standard of care control arm. The study has 2 parts: Part 1: All required study visits for subjects who initially receive study treatment and those who receive standard of care therapy (control arm). Part 2: Subjects who are enrolled in the control arm may receive treatment with AVB-114 following week 36. Those subjects then will be followed as specified in the clinical protocol.

Oral Antibiotics for Anal Abscess

Anal FistulaAnal Abscess

BACKGROUND Anal abscess and perianal fistula is a high prevalence disorder in general population that affect adult patients on young ages, affecting them significantly their social and quality of life. There is clinical evidence that the origin of most perianal fistulas (60%) is with an episode one year before of a perianal abscess. In fact, the established cryptoglandular hypothesis considered the origin of anal fistula, a chronic infectious disease starting on a clinical episode of an anal glands abscess. However, controversy exists regarding the role of antibiotics in the development of anal fistula after incision and drainage of perianal abscess. Nowadays, only two single-centre randomized controlled trials has been published addressing this issue, with inconclusive results. The MAIN OBJECTIVE of the study is to examine the clinical benefit of antibiotic therapy in patients with a perianal abscess, to avoid the development of a perianal fistula. METHODOLOGY We designed a prospective, multicentre double-blind placebo trial to analyse the clinical benefit of a course of antibiotics after perianal abscess drainage to diminish the probability of development of perianal fistula in the follow up of patients. Patients with anal abscess will be allocated randomly either to receive 7 days of oral metronidazole/ciprofloxacin in addition to their standard care or to receive standard care and placebo, after they will be discharged from the hospital. Patients will be followed clinically at different intervals during one year in order to know if they develop anal fistula. Also a quality of life assessment at the end of the study will be evaluated. EXPECTED RESULTS We expected that patients allocated to antibiotic treatment would develop a significant less anal fistulas in their follow-up with a related significant better quality of life. Thus, a change on standard of care led by our group, may be achieved.

A Prospective, Randomized Controlled Trial of Stent Graft and Drug Coated Balloon Treatment for...

Neointimal HyperplasiaDialysis Access Malfunction

Arteriovenous Fistula (AVF) is a surgically created circuit used for hemodialysis in patient with End Stage Renal Disease (ESRD). A functioning dialysis vascular access is critical to the delivery of life-saving hemodialysis (HD) treatment for these patients. Unfortunately, neointimal hyperplasia frequently occurs within the dialysis vascular access, resulting in stenosis, poor flow and thrombosis with loss of function. The cephalic vein forms the outflow conduit for radiocephalic (RC) and brachiocephalic (BC) AVF. At the perpendicular portion of the cephalic vein, the cephalic arch is often prone to developing hemodynamically significant stenosis. The prevalence of cephalic arch stenosis is reported to be 39% in brachiocepahlic and 2% in radiocephalic AVF. The current gold standard therapy for treatment of AVF stenosis is plain balloon angioplasty (BA). Paclitaxel coated balloon (PCB) angioplasty has also been shown recently to be superior to plain BA in the treatment of stenosis in dialysis vascular access. By releasing paclitaxel, which is an anti-proliferation drug, locally into the vessel wall during balloon contact, it will blunt the acceleration of intimal hyperplasia response, resulting in improved primary patency after angioplasty. The use of stent grafts for recurrent CAS has been demonstrated to increase patency of AVF compared to BA and bare stents. However, stent grafts are prone to edge restenosis that tend to occur within 5mm of each end of SG due to neointimal hyperplasia from the end of the stent migrating towards the center. We postulate that stent graft with PCB angioplasty of the stent edge is more effective than PCB alone in maintaining the patency of AVF with cephalic arch stenosis. Therefore, we aim to perform a randomized controlled trial to compare the 6-month unassisted patency rate of treatment of recurrent CAS with stent graft and PCB angioplasty of both stent edge versus PCB alone.

Clinical Study on Autologous Platelet-rich Plasma (PRP) Treatment for Tracheobronchial Fistula

Tracheobronchial Fistula

Platelet-rich plasma(PRP), is a concentrate of platelet-rich plasma protein derived from whole blood. The main components of it are platelets, leukocytes and fibrin. Autologous PRP treatment can avoid the immune rejection caused by exogenous growth factor and the spread of disease. Evidence of the efficacy and safety of PRP has been proven in many studies. Tracheobronchial fistula(TBF) refers to a pathological state in which there are abnormal passages between the trachea, bronchi and chest, esophagus, stomach, mediastinum, bile ducts and other organs or cavities. Bronchopleural fistulas and tracheobronchioesophageal fistulas are two common types og TBF, which are mainly manifested as choking on eating and repeated aspiration pneumonia. Respiratory intervention has become one of the most common treatments to fight the disease. Although the short-term occlusion effect of conventional treatment methods of respiratory intervention is relatively easy to achieve, there is great uncertainty in the long-term treatment effect, and long-term large fistulas have little chance of healing. PRP has shown significant efficacy for hyperplastic scar of skin. Correspondingly, PRP will be applied as treatment of TBF to cure fistula.

Efficacy and Safety of TPIAT for Resectable Adenocarcinoma of the Pancreas Region at High Risk of...

Adenocarcinoma of the PancreasAdenocarcinoma of the Duodenum1 more

Curative management of locally resectable invasive adenocarcinomas located in the cephalic region of the pancreas (pancreas, duodenum and ampulla of Vater) requires a pancreaticoduodenectomy followed by adjuvant chemotherapy. Pancreaticoduodenectomy is a major surgery that often leads to major complications including approximately 20% of relevant clinical postoperative pancreatic fistula. Postoperative complications following pancreaticoduodenectomy can lead to early discontinuation of the complete oncologic strategy, i.e., chemotherapy for malignancy is performed in only about a third of patients who experienced a grade C fistula. A total pancreatectomy rather than a pancreaticoduodenectomy is an alternative procedure that involves the complete and definitive resection of all pancreatic tissue, eliminating any risk of postoperative pancreatic fistula but is associated with unavoidable endocrine insufficiency and potentially severe metabolic complications, such as "brittle diabetes". Total Pancreatectomy following by intraportal Islet AutoTransplantation (TPIAT) can prevent "brittle diabetes" and improve the quality of life. The endocrine islets can be isolated from the pancreatic surgical specimen with standardized procedures and transplanted in the liver through intraportal infusion, in absence of immunosuppression and allow adequate control of glucose metabolism with a reduced need for exogenous insulin and an effective graft function in 70% of cases at 3 years Thereby, the investigators hypothesize that total pancreatectomy with intraportal Islet autotransplantation rather than classical pancreaticuduodenectomy, in patients with high-risk of postoperative fistula will increase the rate of complete access to adjuvant chemotherapy, while maintaining an adequate metabolic control.

ACCESS HD: Comparing Catheters to Fistulas in Elderly Patients Starting Hemodialysis

End-stage Kidney Failure

This randomized controlled trial (RCT) is multi-center, parallel-arm, and open label. It will test the feasibility and safety of randomizing elderly patients with end-stage kidney failure starting hemodialysis with a tunneled/non-tunneled catheter to one of the following vascular access strategies: (a) attempt at fistula creation (intervention), or (b) continued use of a catheter (comparator). A total number of 100 participants will be enrolled in vanguard phase of the RCT. The rationale for this trial includes: (1) the importance of the intervention question related to the choice of vascular access for patients treated with hemodialysis; (2) lack of evidence from clinical trials for decision-making in this area (only observational studies are available); (3) existing studies which suggest that fistula use is associated with better patient outcomes are very prone to selection bias; (4) need for a clinical trial comparing the impact of the two most frequently chosen strategies for vascular access (catheter and fistula) in the hemodialysis population; and (5) a feasible and safe trial design. The results obtained from this vanguard phase of the RCT will determine the feasibility and safety of conducting a large RCT, which will be powered for the primary outcome of days spent in hospital.
