NCT ID: NCT06391281 Not yet recruiting - Hemodialysis Clinical Trials

Effect of Fistula Training in Hemodialysis Patients

Start date: April 26, 2024
Phase: N/A
Study type: Interventional

It was planned to examine the effect of fistula-related education given to patients receiving hemodialysis treatment on their self-care behaviors. Nurse-led education about fistula for hemodialysis patients affects fistula self-care behaviors. Nurse-led training regarding fistula to hemodialysis patients does not affect fistula self-care behaviors.

NCT ID: NCT06386835 Recruiting - Fistula-in-ano Clinical Trials

Collagen Paste vs Mucosal Advancement Flap for FIA

Start date: January 26, 2024
Phase: N/A
Study type: Interventional

The treatment for fistula-in-ano (FIA) remains a challenge to General and Colorectal Surgeons Worldwide. A variety of surgical treatments have been described for high anal fistulas, but none offers the panacea of fistula eradication with guaranteed preservation of continence. This study compares Collagen paste injection to mucosal advancement flap for the treatment of fistula-in-ano.

NCT ID: NCT06380036 Completed - Fistula in Ano Clinical Trials

Two Approaches to Lower the Chances of Recurrence of Anal Fistula After Surgery

Start date: November 1, 2022
Phase: N/A
Study type: Interventional

A total of 80 patients with complex fistula in ano of both genders were included. All patients in Group A underwent a loose seton technique. In group B, video-assisted fistula tract surgery (VAAFTS) was performed.Twice daily Sitz baths, analgesics, and stool bulking agents (bran) were used in follow-up care. Repeated examinations were carried out every four weeks and recurrence was noted at the end of three months

NCT ID: NCT06365489 Active, not recruiting - Clinical trials for Vascular Access Complication

Comparison of Brachial Wrist Index Before and After Implantation of Arteriovenous Fistulas, Based on Brachial Artery

Start date: December 11, 2022
Phase:
Study type: Observational

Arterio-Venous Fistula (AVF) is the most recommended vascular access for hemodialysis. Steal syndrome is a potential complication of AVF implantation and occurs secondary to diversion of the arterial flow of a limb to the venous system resulting in limb ischemia. Measuring wrist pressure compared to arm pressure before and after fistula implantation can be a suitable tool in predicting the possibility of Steal syndrome. In this study, the ratio of wrist to arm pressure and its relationship with Steal syndrome symptoms before and after fistula implantation are investigated.

NCT ID: NCT06335862 Not yet recruiting - Oesophageal Atresia Clinical Trials

Primary Posterior Tracheopexy Prevents Tracheal Collapse

PORTRAIT
Start date: April 1, 2024
Phase: N/A
Study type: Interventional

Introduction: Children born with a blind-ending gullet (oesophagus), or Oesophageal Atresia (OA), need to undergo surgical correction in the first week of life. OA is often accompanied by a weakened windpipe (trachea), known as tracheomalacia (TM). TM entails that the windpipe collapses during expiration. Severe TM can cause respiratory symptoms, including frequent respiratory tract infections and blue spells, that can potentially lead to life-threatening events. In some patients, major secondary surgical treatment may be indicated. This surgical procedure involves widening the trachea (using sutures) to prevent collapse, known as secondary posterior tracheopexy (SPT). Prior to performing this SPT, complications and negative consequences of TM may have already occurred. This may be prevented by performing this procedure during the primary OA correction, called a primary posterior tracheopexy (PPT). The aim of this trial is to determine if a PPT can decrease - or prevent - tracheal collapse in newborns with OA and TM, compared to a wait-and-see policy (no-PPT). Methods: This is an international multicentre double-blind randomised controlled trial. Seventy eight children with OA type C will be included. Patients will be included after written parental informed consent. Half of the patients will be randomly allocated to the PPT-group and half to the no-PPT-group. The degree and location of TM are evaluated through preoperative, intraoperative and two postoperative videoscopic examinations of the trachea (tracheobronchoscopy). Whether TM symptoms occur is assessed during three routine follow-up consultations until the age of 6 months. The primary outcome is the degree of collapse of the tracheal wall during the intraoperative tracheobronchoscopy (after performing the PPT/no-PPT), measured in percentages. Risks and burden: Since OA correction with PPT (more recently implemented in centres of expertise) and without PPT (wait-and-see policy) are both accepted and safe treatment options, participating in the trial does not pose an increased risk or burden with regards to the treatment. Performing tracheobronchoscopies may pose a potential burden. However, a tracheobronchoscopy is a routine diagnostic procedure commonly used to safely assess the trachea. Complications of a tracheobronchoscopy are rare. Also, many of the tracheobronchoscopies are routinely performed as part of standard care for these patients, regardless of the trial.

NCT ID: NCT06322680 Recruiting - Clinical trials for Pancreaticoduodenectomy

Impact of External Drainage of the Main Pancreatic Duct and Common Bile Duct on Pancreatic Fistula Following Pancreaticoduodenectomy

Start date: May 20, 2024
Phase: N/A
Study type: Interventional

Pancreaticoduodenectomy (PD) is the standard treatment for tumors of the pancreatic head, distal bile duct, duodenum, and ampulla of Vater. With advances in surgical experience and instrumentation, the mortality rate of PD has decreased to below 5% in high-volume pancreatic centers. However, the postoperative complication rate remains high at 25%-50%, limiting the development and application of PD. The main postoperative complications of PD are postoperative pancreatic fistula (POPF), delayed gastric emptying (DGE), post-pancreatectomy hemorrhage (PPH), and biliary leakage (BL). POPF, BL, and the subsequent abdominal infection, PPH, etc. are the main causes of death during hospitalization. Even in large, relatively mature pancreatic centers, the incidence of POPF remains as high as 10%-40%. In recent years, various methods have been used to prevent and treat POPF and BL after PD, such as pancreatic duct stent external drainage and external biliary drainage. To date, there have been many studies by domestic and foreign scholars on the advantages and disadvantages of biliary and pancreatic duct external drainage versus internal drainage in PD in terms of perioperative POPF incidence, mortality rate, etc., but the research results are not consistent. Overall, pancreatic duct stent external drainage is only recommended for patients with a high risk of pancreatic fistula during PD. Currently, there have been a few relevant studies exploring and verifying the preventive effect of pancreatic duct stent external drainage on pancreatic fistula in patients with high risk of pancreatic fistula. For example, a retrospective study of 98 patients with soft pancreatic parenchyma by Teruyuki Usub et al. found that there was no significant difference between groups with and without pancreatic duct stent in preventing pancreatic fistula. However, due to the low level of evidence, only a few risk factors such as pancreatic texture and pancreatic duct diameter were included, and the risk of POPF was not systematically evaluated. Further clinical exploration and verification are needed. In 2013, Mark P Callery et al. proposed a pancreatic fistula risk score (The fistula risk score, FRS) based on the pancreatic fistula standard defined by the International Pancreatic Fistula Study Group, which included pancreatic texture, pathological type, pancreatic duct diameter, and intraoperative blood loss. This model can be used to systematically and quantitatively evaluate the risk of POPF. Previous studies did not have a clear stratification for patients undergoing pancreatic duct stent external drainage, which may have included too many patients with a low risk of pancreatic fistula, resulting in inaccurate results. Therefore, it is necessary to re-evaluate the effectiveness of pancreatic duct stent external drainage in preventing clinically relevant pancreatic fistula based on stratification of pancreatic fistula risk and disease type. At the same time, pancreatic juice contains a variety of digestive enzymes, of which pancreatic lipase, trypsin, and chymotrypsin all need to be activated by bile to play a role in digesting and decomposing fat and protein. Theoretically, biliary and pancreatic juice diversion may be able to reduce the incidence of pancreatic fistula and its related complications in PD patients. Thus, the investigators design the present study to evaluate the impact of main pancreatic duct and biliary duct external drainage on postoperative complication, especially POPF.

NCT ID: NCT06314945 Completed - Perianal Fistula Clinical Trials

Diagnostic Value of Recto-perineal Ultrasound in Perianal Fistula

Start date: September 1, 2023
Phase:
Study type: Observational

Perianal fistula is a common anal problem. It needs only surgery. MRI is the best preoperative diagnostic tool, but it is demanding as it is expensive, time consuming and needs an experienced radiologist. So, we tried to find an alternative diagnostic tool which is cheaper, time saving and accurate and comparing its preoperative reports with intraoperative findings. study was held in surgery department in Zagazig University Hospitals from September 2023 to March 2024. It included 93 patients with perianal fistula who were diagnosed clinically and radiological by trans recto-perineal ultrasound and comparing pre-operative ultrasound findings with intra-operative surgical findings.
