Active clinical trials for "Fistula"

Obstetric fistula, also called vaginal fistula, is a serious medical condition which affects women in low income countries. Despite the strengthening of research on fistula, there is little data on the follow-up after fistula repair. The objective of this study is to analyse the factors associated with the recurrence of fistula and the outcomes of pregnancy following fistula repair in Guinea. It will target women who got a closed fistula at discharge after repair in 2012/2015 at three fistula repair sites supported by the Fistula Care Project in Guinea (Kissidougou Prefectoral Hospital, Labé Regional Hospital and Jean Paul II Hospital of Conakry). The outcomes of interest are fistula recurrence and pregnancy. The predictors of interest will include patient characteristics, fistula characteristics, the context of repair and the context of reintegration. Participants giving an informed consent after a home visit by the Fistula Counsellors who managed women during surgery will be interview at enrolment and every six month from inclusion. The study duration is estimated at 48 months (January 2012 to March 2016) including the retrospective part. A sample size of 364 women will estimate the recurrence of fistula with a plus/minus 2% margin of error (width of confidence interval is 4%) and 95% confidence interval and is sufficient to estimate the rate of pregnancy with a two-sided 95% confidence interval and 10% precision. The cumulative incidence rate of fistula recurrence will be calculated using Kaplan-Meier methods and the risk factor analysis will be performed using adjusted cox regression. For the outcomes of pregnancy, Pearson's Chi Square (χ2) will be used to compare proportions of pregnancy outcomes between potential predictors and logistic regression models will be used and associations will be reported as risk ratios with 95% confidence intervals. Analysis will be done using STATA version 13 (STATA Corporation, College Station, TX, USA) with a level of significance set at P<0.05.

Evaluate access to healthcare, comprehension of pre-operative counseling and post-operative goals of women treated for vesicovaginal fistula in Niger through use of a questionnaire.

Postoperative pancreatic fistula is a potentially fatal sequela with substantial morbidity and mortality. A retrospective observational study was conducted in the surgical unit of Zagazig university hospital . Three hundred forty-seven patients were admitted with a clinical diagnosis of pancreatic fistula following both open and laparoscopic approaches for pancreatic benign and malignant tumors.

The aim of this study was to assess the risk and complications after preoperative drainage of biliary obstruction in patients who underwent pancreatoduodenectomy. A retrospective cohort study of all patients who underwent pancreatoduodenectomy from January 1st, 2015 to September 30th, 2021. Patients who had preoperative bile duct drainage were compared to patients without intervention. Type of interventions, complications and outcome after surgery were compared using univariate and multivariate analysis.

The LIFT+Biodesign® study is a post-market observational study to evaluate the rate of fistula closure in patients with persistent trans-sphincteric anal fistula who receive the Biodesign® Tissue graft as part of their LIFT procedure.

A prospective longitudinal surveillance for a period of 2 months. Sample - identify suitable Chronic Kidney Disease (CKD) patients who undergo HD with functioning AVF. Participants at various age range and both sexes are recruited to observe their access flow, access recirculation and cardiac function and assess their relationship.

The study aims to evaluate the use of 3D endoanal ultrasound in preoperative management of anal fistula disease.

Study of the features of hemodynamic and clinical maturation of the native arteriovenous fistula for hemodialysis.

To investigate the associated risk factors of rectovaginal fistula

Vascular access (VA) is the most important for carrying out hemodialysis, yet it may bring in complications and leads to hemodialysis quality decline. This study aimed to explore the impact of vascular access types, including temporary vs.long term hemodialysis catheter on central vein stenosis.
