Background:
Management of enterocutaneous fistulas in Crohn's disease is challenging. Most patients still need intestinal resection in the biologic era.
Objective:
The aim of this study was to evaluate the efficacy of endoscopic treatment for enterocutaneous fistulas.
Design:
This is a retrospective study of medical records.
Settings:
This study was conducted in a single institution.
Patients:
All consecutive patients with Crohn's disease with an enterocutaneous fistula who underwent endoscopic fistula closure with the use of an over-the-scope clip or a hemostatic clip were included.
Main Outcome Measures:
The main outcome measured was the clinical success 3 months after the procedure, which was defined as the complete closure of all fistulas at physical examination and complete cessation of the drainage from the external opening, without surgery.
Results:
Eight patients (men, 25%; median age 45 years [interquartile range, 33-51]) were followed. Fistulas were localized at the ileocolonic or colocolonic anastomosis in 7 patients and at the stomach in 1 patient. Seven patients were treated with an over-the-scope clip, and one was treated with a hemostatic clip. Technical success was achieved in all cases. Clinical success at 3 months was achieved in 75% of cases (6/8 patients). After a median 16-month (interquartile range, 13-23) follow-up, 3 of 8 (37.5%) patients had enterocutaneous fistula closure and 2 of 8 (25%) needed intestinal resection. No complications were observed.
Limitations:
The retrospective nature, the small sample size of the study, and the heterogeneity of the population limit the interpretation of the results.
Conclusions:
Endoscopic treatment of enterocutaneous fistulas is feasible with a short-term effectiveness. Additional studies are needed to confirm these results. See Video Abstract at http://links.lww.com/DCR/B614.
Tratamiento Endoscpico De Fstulas Enterocutneas En Enfermedad De Crohn:
ANTECEDENTES:Es desafiante el manejo de las fístulas enterocutáneas en enfermedad de Crohn. En la era biológica, la mayoría de los pacientes todavía requieren de resección intestinal.OBJETIVO:Evaluar la eficacia por tratamiento endoscópico de fístulas enterocutáneas.ENTORNO CLINICO:Estudio retrospectivo de registros médicos.AJUSTE:Realizado en una sola institución.PACIENTES:Se incluyeron todos los pacientes consecutivos con fístula enterocutánea en enfermedad de Crohn, sometidos a cierre endoscópico de la fístula con clip sobre el endoscopio o clip hemostático.PRINCIPALES MEDIDAS DE VALORACION:El éxito clínico a los 3 meses después del procedimiento. Definido al examen físico, como el cierre completo de todas las fístulas y cese completo del drenaje por la abertura externa, sin cirugía.RESULTADOS:Se estudiaron a ocho pacientes (hombres, 25%, mediana de edad de 45 años (rango intercuartílico, 33-51)). En 7 pacientes, las fístulas se localizaron en la anastomosis ileocolónica o colocolónica y un paciente, en el estómago. Siete pacientes fueron tratados con clip sobre el endoscopio y uno con clip hemostático. Se logró éxito técnico en todos los casos. Se logró éxito clínico a los 3 meses en 75% de los casos (6/8 pacientes). Después de una mediana de 16 meses (rango intercuartílico, 13-23), de seguimiento 3/8 (37,5%) pacientes presentaron cierre de fístulas enterocutáneas y 2/8 (25%) requirieron resección intestinal. No se observaron complicaciones.LIMITACIONES:Estudio retrospectivo, pequeño tamaño de la muestra y heterogeneidad de la población, limitaron la interpretación de los resultados.CONCLUSIONES:Es posible el tratamiento endoscópico de fístulas enterocutáneas con efectividad a corto plazo. Se requieren nuevos estudios para confirmar estos resultados. Consulte Video Resumen en http://links.lww.com/DCR/B614. (Traducción-Dr. Fidel Ruiz Healy).

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
