Active clinical trials for "Intestinal Fistula"

Gastrointestinal leaks or perforations are currently treated through either open or laparoscopic surgical procedures. The purpose of this research is to determine whether new endoscopic tools are safe and effective in the treatment of such conditions and can overcome the need of invasive surgical procedures.

The purpose of this study is to determine safety of Stromal Vascular Fraction (SVF) for the treatment of enterocutaneous fistula.

To Investigate whether different routes of nutrition affect the probability of fistula closure in patients with an enterocutaneous fistula

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.

This is a prospective observational study of patients undergoing planned surgery for intestinal failure. The aims of the study are: To prospectively characterise preoperative bacterial populations amongst patients undergoing surgery for intestinal failure To examine the relationship between preoperative bacteriology and surgical site infection (SSI) in this patient group To investigate the effect of surgery and surgical site infection on generic and wound specific quality of life measures

Liver transplantation enhances the prognosis of patients with cirrhoses or hepatocellular carcinoma. However some patients develop intestinal perforations for which the prognosis is poor. The aim of the study is to evaluate the risk factors of intestinal perforations using a retrospective study scheme.

For non-healing ulcers, abnormal periods of wound healing processes: inflammation, proliferation and remodelling, are believed to lead to chronic wounds. As a chronic "stalled" wound, investigators hypothesized that these glue-assisted closure (GAC)-failed enterocutaneous fistula (ECF) might have a prolonged inflammatory phase modulated by excessive pro-inflammatory cytokines or proteases. The aim of this study was to analyze the chemicals in ECF wounds in order to determine patients' condition and fitness for GAC.

Colovesical fistulas are well-recognized but relatively uncommon pathology to both the general and colorectal surgeon. It is a complication arising from an underlying primary acute to chronic inflammatory process. Although colovesical fistulas are uncommon, they are associated with significant morbidity, affect quality of life, and may lead to death, usually secondary to urosepsis. Early diagnosis and management is essential. The purpose of the study is to determine the objective use of cystographic evaluation on postoperative day two to guide early Foley catheter removal post colovesical fistula takedown. The hypothesis is that a cystogram showing no extravasation of contrast on postoperative day two will predict safe removal without increased morbidity. This is an uncontrolled, single arm trial. Patients who meet criteria to undergo either minimally invasive or open colovesical fistula takedown with sigmoid colectomy, without evidence of the need for bladder repair will be eligible to participate. An indwelling Foley catheter is placed intraoperative and continued postoperative. All patients who consent to participate would undergo a cystogram on postoperative day two. The cystogram will be conducted by a radiologist and technician well-trained in the techniques and interpretation of the study. The colorectal surgery enhanced recovery protocol will be followed on all patients with the exception of the cystogram being conducted on post-op day two. If there is no evidence of extravasation of dye is seen on the cystogram the Foley catheter will be removed. Patients will be monitored closely following catheter removal to ensure self-diuresis.

Observative and descriptive study of 10 patients, which were diagnosed with a Cholecystoduodenal fistula, All electronic medical records were retrospectively reviewed.

The alpha2 agonist dexmedetomidine is a new sedative agent combined with the analgesic qualities and lack of respiratory depression. Patients sedated with dexmedetomidine could be easily roused, these advances shows dexmedetomidine may be a effective and safe sedative agent. But some studies showed some adversely effects of dexmedetomidine on haemodynamics (such as bradycardia, hypotension), the investigators want to further research the effects of dexmedetomidine on haemodynamics, such as Cardiac Output (CO), Systemic Venous Resistance Index(SVRI), and so on. Propofol is widely used sedative agent in ICU, it also has adversely effects like bradycardia and hypotension, so the investigators want to compare the effect of dexmedetomidine with propofol on haemodynamics after major abdominal surgery. Expect to further research the mechanism of haemodynamics of dexmedetomidine.
