入选标准
- •Patients with complex fistulas
- •Complex fistulas include trans-sphincteric fistulas involving more than 30% of the external sphincter, supra-sphincteric fistulas, extra-sphincteric fistulas, horseshoe fistulas, fistulas involving multiple tracts (according to the ASCRS) and fistulas with a curved tract or a tract presenting diverticula, for which:
- •Suppuration is described by the patient and/or visible by an opening in the anal margin or by anoscopy Clinical symptoms led to an MRI demonstrating the path Fistula path demonstrated in the acute phase during drainage of an abscess
- •Patient ≥ 18 years at study entry
- •Patients with a previously drained fistula, without diverticula > 10 mm, without T2 hyperintensity (assessed by MRI). Drainage is achieved by placing a seton, usually from 10 weeks to 12 months prior to the procedure
- •Patient and investigator signed and dated the informed consent form prior to the procedure
排除标准
- •Patient < 18 years at study entry
- •Patient has a known contraindication to treatment using radiofrequency (infectious anal pathologies, anal fissures, residual Longo anterior treatment staples)
- •Patient has a known contraindication to MRI
- •Simple fistulas defined as inter-sphincteric or trans-sphincteric, involving less than 30% of the total height of the sphincter apparatus (attested by MRI, ASCRS classification)
- •Patient has a fistula associated with radiation and inflammatory bowel disease
- •Patient is unable/unwilling to provide informed consent
- •Patient is unable to comply with the protocol or proposed follow-up visits and questionnaires
- •Patient is currently participating in another clinical study
- •Patient is pregnant

结局指标
主要结局
Healing rate, clinically and MRI-assessed, at 12 months during an in-hospital visit
时间窗: 12 months
MRI-assessed healing (deep healing) is defined as a fibrous tract, a scarred tract, or a tract that is not visible on MRI. If the tract is shown to be inflammatory, liquid, or showing presence of diverticula, healing is considered to be not achieved. Clinical healing is defined as closure of the internal and external openings without inflammation or discharge or symptoms. Internal opening closure is confirmed by the absence of discharge and external opening closure is confirmed by visual and digital examination.
次要结局
- Anal incontinence at 2 weeks, and 2, 6 and 12 months(2 weeks, 2 months, 6 months, 12 months)
- Mean amount of energy used per treatment(At procedure)
- Return to daily activities at 2 weeks(2 weeks)
- Healing rate per type of fistulas treated(12 months)
- Healing rate without anal incontinence at 12 months(12 months)
- Rate and nature of late and immediate postoperative complications(At procedure, 2 weeks, 2 months, 6 months, 12 months)
- Duration of the procedure(At procedure)
- Return to work at 2 weeks(2 weeks)
- Quality of life at 2 weeks, and 2, 6 and 12 months(2 weeks, 2 months, 6 months, 12 months)
