Active clinical trials for "Fistula"

The aim of this study is to evaluate whether a local perianal block performed during a proctological intervention can reduce the postoperative pain.

Introduction: A rectovaginal fistula (RVF) is an epithelium-lined abnormal tract between the rectum and the vagina and is often a challenging problem for both the patients and to the surgeons. In literature, there is still debate regarding the best treatment options for rectovaginal fistulas. Aim: To assess the results of the treatment of rectovaginal fistulas with incontinence and impaired anal tonus using fistulectomy, sphincteroplasty with or without bulbocavernosus muscle (Martius) flap. Materials and Methods: A total of 22 consecutive patients with simple RVFs were included and assigned to transperineal repair. The patients were divided into two groups , group1: with Martius flap; group2: without Martius flap .Postoperatively, patients were followed up for one year at the outpatient clinic or through telephone interviews with specific questionnaires to collect information on the status of fecal control, flatus, or fecal leakage from the vagina.

In patients with vesicovaginal fistula, transvesical and extravesical repair will be compared in terms of operative time, complications and recurrence rates.

The aims of this study are to: Determine the AVF (arteriovenous fistula) survival of patients submitted to MuST compared to those submitted to RL (rope-ladder). Determine the AVF (arteriovenous fistula) complication rate of patients submitted to MuST compared to those submitted to RL (rope-ladder). Analyze the intensity of pain perceived by the patient with each cannulation technique under study.

Cerebral blood flow (CBF) is of paramount importance to human brain function, as the brain relies on a continuous blood supply to meet its energy needs. Blockage of a cerebral blood vessel during neurosurgery, even if transient and short-lived, may result in irreversible brain tissue damage (i.e. stroke) and loss of cortical function, if not identified quickly enough. Laser speckle contrast imaging (LSCI) has been demonstrated to provide the ability to visualize flow in vessels in real time and continuously without the need for contrast agents. In LSCI, the tissue of interest is illuminated with low power laser light at red or near infrared wavelengths and the light reflected from the tissue surface is imaged onto a camera. The resulting images are laser speckle patterns and a computer processes the images to produce speckle contrast images, which are images of the motion within the field of view (ie, blood flow). The purpose of this clinical investigation is to assess the usefulness and accuracy of LSCI compared to ICGA and/or FA during neurovascular surgery. LSCI videos will be recorded automatically intraoperatively in each patient before, during, and after ICGA and/or FA in the same surgical field of view to guarantee comparability of the methods.

The purpose of this study is to evaluate the feasibility of closing bronchopleural fistulas with devices originally developed for correction of cardiac septal defects deployed through bronchoscopic procedures.

Pancreatoduodenectomy (PD) is performed in many high volume centers with a very low mortality. Reduced mortality rate is largely the result of careful patient selection, improved intraoperative management and a better postoperative care. Unfortunately, there is not a similar reduction in morbidity rates which remains about 40%. Persistent morbidity is predominantly due to pancreatic fistula (PF). Abdominal abscess and hemorrhage are common sequelae of PF which have been associated with a high mortality rate. While many different risk factors have been reported, a soft pancreatic texture and a nondilated pancreatic duct have been most consistently linked to high rates of PF. A number of methods for reducing the incidence of PF have been proposed and analysed. Many of these involve technical features of the anastomosis, including site of reconstruction, anastomotic technique, use of biologic glue, and prophylactic use of somatostatin analogue. The placement of a stent through the pancreatic anastomosis is an attractive strategy to reduce the PF rate. This multicenter prospective randomized trial was designed to compare the outcome after PD with external drainage stent versus no stent in patients with high risk of PF (with soft pancreas and a diameter of wirsung <3mm). Analysis:The primary objective of the study was to compare the incidence PF in patients with or without external pancreatic stent. With an anticipated PF rate of 30%, based on literature experience, it was calculated that a reduction to 10% of PF rate would require the inclusion of 75 patients in each group (statistical significance P < 0.05 and power 80 per cent with a two-tailed test of proportions). We'll enroll 158 patients to take into account the possibility of 5% being lost to follow-up.

Background: Abdominal wall reconstruction in patients presenting with enteric fistulas and mesh infection is challenging. There is a consensus that synthetic mesh must be avoided in infected operations. The alternatives to using synthetic mesh, such as component separation techniques and biologic mesh, present disappointing results with expressive wound infection and hernia recurrence rates. Methods: A prospective clinical trial designed to evaluate the short and the long-term outcomes of patients submitted to elective abdominal wall repair with synthetic mesh in the dirty-infected setting, and compared to a cohort of patients submitted to clean ventral hernia repairs.

This randomized trial aimed to compare conventional draining seton with or without rerouting of the fistula track in treatment of complex anal fistula
