Design: this study includes two separate groups of cases and controls each consisting of 40 participants randomly allocated for the phase 2 of clinical trial. Settings and conduct: Patients with complex perianal fistula referred to Imam Khomeini hospital, will be included in the study if they contain inclusion criteria. The fistula was evaluated by clinical examination and MRI and patients fill the quality of life questionnaire. Exosome injections are performed weekly for consecutive three weeks. Patients will reexamined and fill the questionnaire and MRI will done 12 weeks later. Recent findings will compare with the initial data. During this period, patients are examine for complications. Main outcome variables: Discharge amount; External orifice re-epithelialization ; Inflammation, discharge and abscess larger than 2 cm in MR imaging; Quality of life questionnaire score, Inflammatory markers such as CRP, IL-6, TNF-a, calprotectin
Randomised Controlled Trial comparing Laser assisted closure of transsphincteric fistula to the rectal advancement flap.
Investigators aim to investigate the changes in patients' quality of life with different type of seton application.
After abscess formation, an anal fistula is a common consequence, with crypto-glandular infection being the most commonly accepted causative cause. The goal of this study was to see how well closure of the inter-sphincteric fistula tract affects the outcome of trans-sphincteric fistula surgery. Patients with perianal trans-sphincteric fistulas who underwent ligation were studied prospectively. All patients had the identical anesthetic approach, followed by the operation with two years' follow-up.
Objective: Rectal advancement flap (RAF) is currently considered the gold standard in the treatment of complex anal fistula (CAF). Clinical trials are a priority given the few consistent results available with level 1 evidence. We compare the results of two conservative sphincter techniques: ligation of intersphincteric fistula tract (LIFT) versus RAF. Material and Method: A controlled, randomised clinical trial is conducted in patients operated between 2013 and 2016 in Hospital General Universitario Reina Sofia, Murcia, Spain. The primary objective was to evaluate relapse at 12 months of follow-up, and the secondary objectives were post-op anal continence (Wexner), post-operative complications (haematoma, infection of surgical site, suture dehiscence), duration of surgery and hospitalisation. Post-operative controls 1, 3, 6 and 12 months after surgery.
This is an observational study designed to evaluate the safety and clinical outcomes of Myriad™ in soft tissue reconstruction procedures. The study will enroll participants who are undergoing a surgical procedure, where the attending physician will use Myriad™ as part of the surgical intervention.
Fistula in ano is a chronic problem for the patients. It causes distressing because of foul odor and soiling with recurrent infection and discharge. Recurrence and anal sphincter injury were the most critical complications following surgery. Loose, thick Seton placement was the most promising surgical operation. To reduce the time of Seton placement, therefore, decreasing the suffering of patients from soiling and multiple dressing.
Complex anal fistula is a fistula whose treatment with fistulotomy would expose the patient to an excessive risk of post-operative continence disorders. It is a challenge in proctological surgery because of the complexity of its therapeutic management in relation to the recurrences' frequency and the need to preserve sphincter function. Indeed, management is mainly based on fistulotomy techniques, but the latter expose patients to a significant alteration of their continence (less than 10% incontinence for simple fistulas but 30-50% for complex fistulas). In addition, these fistulas' management is constraining for patients due to the need for multiple interventions, long-term post-operative care and repeated discontinuation of activity. Sphincteral saving techniques have therefore developed over the last three decades and have enriched the therapeutic panel of complex fistulas. They aim to block fistula pathways without risking altering sphincter function. In addition, their surgical consequences are often simple. However, they are associated with a greater risk of failure than after fistulotomy and sometimes disappointing to the point that some of these techniques have been gradually abandoned (biological glue and plug for example). Among these sphincteral saving techniques, the investigators know the advancement flap, the injection of biological glue, plug's installation, the LIFT (Ligation of Inter sphincteric Fistula Tract), the clip's use but also, more recently a laser treatment, FiLaC™ (for Fistula Laser Closure), knowing that the idea was not new since the ND-YAG3 and CO24.5 lasers were already used in the treatment of anal fistulas, about twenty years ago, in experimental studies. This technique consists of radiating 360° laser energy radially into the fistula path to "burn" it and causing thermal destruction by coagulation of the fistula wall ans granulation tissue2. It can bo offered to any type of fistula at risk on continence, including horseshoe extensions that can be treated at the same time. It is well suited for outpatient management because the postoperative period is simple and painless. The literature is still poor on the subject with some studies published openly but the preliminary results are encouraging with a success rate of about 70%. No continence disorders reported.
To improve the outcome of LIFT, some authors used a combined approach of LIFT. Pooled analysis of seven studies including 192 patients revealed a success rate of 83.5 % after combined LIFT approach. The use of bone marrow aspirate concentrate (BMAC) in surgery is not entirely new as it has been widely used in the treatment of bone defects, mandibular reconstruction, maxillary sinus augmentation and in critical limb ischemia. A previous study concluded that the use of BMAC to augment external anal sphincter repair strengthens wound healing by transferring cells responsible for healing directly to the site of repair. The current study aimed to assess the outcome of local injection of bone marrow mononuclear cells (BM-MNCs) in conjunction with LIFT as compared to LIFT alone in regards to healing rate, time to healing, and ultimate success rate.
This study aimed to compare the efficacy of the decompression and drainage seton (DADS) and cutting seton (CS) in the treatment of high complex anal fistula.
