Filter by:Currently, the treatment of Crohn's patients with perianal fistulas predominantly exists of anti-TNF medication. However, its efficiency has never been directly compared to surgical closure of the perianal fistula. The aim of this study is to compare radiological fistula healing at MRI after 18 months follow-up in Crohn's patients undergoing surgical closure to anti-TNF medication as treatment of perianal Crohn's fistulas. Study design: In this multicenter comprehensive cohort design (CCD) Crohn's patients with a (re)active high perianal fistula will be allocated to anti-TNF for 1 year or surgical closure after 2 months under a short course of anti-TNF. Patients with a distinct preference will be treated accordingly, whereas only indifferent patients will be randomised in the usual way. Main study parameters/endpoints: The primary outcome parameter is the number of patients with radiologically closed fistulas based on an evaluated MRI-score after 18 months. Secondary outcomes are clinical closure, number of patients undergoing surgical re-interventions and number of re-interventions, recurrences and quality of life based on the Perianal Disease Activity Index (PDAI). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: All patients will receive one of the two standard treatment approaches that are currently used for Crohn's fistulas. All effort has been performed to ensure most optimal treatment, according to best available evidence and current guidelines. Since there is no experimental study-arm, there are no additional risks associated with participation. During the study, the medical staff and trial nurses will monitor the necessity of surgical interventions and hospitalizations. At baseline and after 18 months all patients will undergo a MRI to score the fistula. Secondary outcome parameters will be assessed during visits to the outpatient clinic or telephone consultations at baseline and at intervals of 3 months for the duration of the study period. Every 6 months patients were asked to fill out the PDAI questionnaire with their physician. Based on the available literature, radiological closure of fistulas is expected in 40% of patients in the surgical closure group compared to 15% in the anti-TNF group. The increase in closure rate from 15% to 40% is considered clinically relevant. Due to the combination of a preference and randomized cohort, the appropriate sample size to detect this 25% difference is flexible and is adjusted for a skewed distribution. The minimal sample size, in case of a 1:1 treatment allocation, needed to detect this difference with a Chi-square test equals 86 patients (alpha 0.05, power 80%). The maximal allowed skewed distribution is set at 1:4, which will result in a maximal sample size of 116 patients.
The goal of this observational study is to understand the effects of anatomical factors, etiology, and complexity of anal fistula on the prognosis of patients undergoing anal fistula surgery within one year post-operation.The main question it aims to answer is: Which factors are indicative of the prognosis of anal fistula surgery? Which factors are landmark factors of anal fistulas? Participants who have already undergone anal fistula surgery at our hospital will receive outpatient and telephone follow-up to assess their prognosis.
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
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.
the study evaluated the one stage endoscopic middle meatal antrostomy (EMMA) technique with the application of a platelet rich fibrin membrane (PRF) for Oroantral Fistula (OAF) closure and relief of maxillary sinusitis.
It was conducted to investigate the effect of ice application to the kaleidoscope and hoku point on the management of cannulization-related pain in patients receiving hemodialysis treatment.
The goal of this observational study is to compare the presentation, treatment, and outcomes in patients suffering traumatic pancreatic injuries from blunt or penetrating trauma. The questions this study aims to answer are: 1. Does a statistically significant association exist between pancreatic injury grade and the following individual factors: - Mortality - Morbidity - Injury severity score 2. Is there an association between post-operative pancreatic complications and operation-specific intervention? 3. Does pancreatic injury score correlate with certain intra-abdominal organ injuries? Participants meeting criteria are greater than 18 years old, with no history of pancreatic surgery who were hospitalized at Kern Medical Center after presenting to the institution's emergency department as tier 1 or 2 trauma activations following blunt or penetrating abdominal injury and were diagnosed with pancreatic injury during the same hospitalization.
This is a prospective, double-blinded randomised controlled trial conducted at two tertiary hospitals by a credentialed colorectal surgeon.
This study is a retrospective cohort study aimed at evaluating the impact of autologous arteriovenous fistula (AVF) on the heart, especially the left atrial structure, in patients with end-stage renal disease (ESRD) through a retrospective cohort study. The aim is to further clarify the relationship between the establishment of AVF and the occurrence of atrial fibrillation, and provide a theoretical basis for exploring the relevant mechanisms of AVF induced atrial fibrillation in the future.
The study conducted a retrospective analysis from January 2018 to December 2022 on patients who received anal fistula closure with Obsidian RTF® at the Department of General Surgery, Medical University of Vienna.
