Active clinical trials for "Fistula"

Primary Objective: To evaluate the clinical efficacy of Naturetti (jelly sugar free) To test medication on subjects who suffer chronic functional constipation in 30 days use. Secondary Objectives: To demonstrate the clinical tolerability when daily used (repeated doses) of the components of the study drug. The components will be evaluated by the adverse events occurrence classified by possibly related, probably related and definitely related To demonstrate the clinical tolerability of the study medication by the continuous use during the second phase study To identify any adverse events related to the study drug To identify any drug interaction.

The primary objective of this study is to evaluate the effect of topically applied heparin in comparison to placebo on suitability of newly constructed primary arteriovenous fistulas in patients planned for haemodialysis at 7th week (± 1 week) after first study drug administration.

This study is designed to assess the preventive effects of somatostatin on post-operation pancreatic fistula in intermediate risk patients after pancreaticoduodenectomy. Patients assigned into the treatment group will be continuous intravenous infusion with the somatostatin (Stilamin®) in addition to conventional treatments (including infection prevention, nutrition support and acid suppression therapy, etc.).The pancreatic fistula incidence will be monitored within 30 days after operation.

A new strategy for treatment of late radiation damage is to develop methods aimed at stimulating the regenerative capabilities of irradiated tissues. Since the main pathogenetic mechanism of the development of late radiation damage is the death or damage of the replicative mechanism of stromal cells (SC), a justified approach can be considered as transplantation of intact SC. Currently, there is convincing evidence in the scientific literature that the injection of intact autologous SCs into the zone of fibrosis surrounding the chronic radiation ulcer leads to the healing of a wound defect. An Initiative Clinical Trial. Introduction of autologous regenerative cells of adipose tissue for the treatment of post-irradiation vaginal-rectal fistula. It is assumed that patients will be included in the project within 12 months; the monitoring of each patient will last for 6 months; the total duration of the clinical part of the study will be 18 months; The total duration of the clinical trial including the preparatory phase and the writing of the report is about 24 months. It is assumed that at least 16 patients aged 20 to 75 years who have verified diagnosis of post-irradiation vaginal-rectal fistula will participate in this pilot project. The aims of the clinical trial are to preliminarily assess the safety, effectiveness and quality of life of patients after introducing autologous regenerative cells of adipose tissue for the treatment of post-irradiation vaginal-rectal fistula.

To evaluate the safety and efficacy of Paclitaxel Eluting Hemodialysis Shunt Balloon Dilatation Catheter (APERTO) compared with the Balloon Dilatation catheter (OHICHO II) for the treatment of Arteriovenous Fistulae Stenosis in patients undergoing hemodialysis.

This trial is aimed to evaluate the safety and efficacy of DCB in treating AVF stenosis in chinese population.

A pilot study to investigate the safety and feasibility of stem cells treatment of complex anal fistula in patients with Crohn's disease.

A cohort including more than 100 maintenance hemodialysis patients will be followed up according to a certain Following-up System of Native Arteriovenous Fistulae (AVF) prospectively. The assessment results of the Following-up System of AVF help the physicians make decisions of AVF surgery and puncture methods. The results of this study would identify the effect of the system on survival of AVF. Other 100 hemodialysis patients from other centers will be treated by routine protocol and compared to the experiment goup.

In the treatment of complex anal fistulas transplant of freshly collected autologous adipose tissue mechanically fragmented or centrifuged adipose tissue (CAT) might be an alternative to in vitro expanded autologous or allogeneic adipose-derived stem cells, showing remarkable efficacy in diverse therapeutic indications. The aim of our study is to evaluate randomly the efficacy and safety of the use of CAT in the healing process of complex anal fistulas, except for Crohn's disease (CD) related fistulas.

In this study, we retrospectively reviewed clinical data of patients who were treated with an anal fistula plug for trans-sphincteric anal fistulas, and evaluated the long-term therapeutic effect of an anal fistula plug and the risk factors impacting anal fistula healing. In addition, we assessed the effects of post-operative changes on anal function, as well as the risk factors affecting anal function.
