As a chronic condition, pilonidal disease affects a young population, and recovery after the surgical procedures performed to treat this condition require time off from work. Therefore, the search for an ideal treatment is still ongoing. The aim of this study was to compare early and late results of 2 minimally invasive treatment options used to treat pilonidal disease. This study was designed as a parallel group randomized clinical trial. This study took place at an outpatient clinic in Turkey. Patients with pilonidal disease were evaluated for the study and were enrolled if they met the inclusion criteria and gave informed consent. Patients in the platelet-rich plasma group were treated using curettage + platelet-rich plasma gel. Patients in the phenol group were treated by using curettage + crystallized phenol. The primary study end point was the time to achieve healing; the secondary outcome was recurrence rate. In the platelet-rich plasma group, 96% of patients achieved healing after 1 application. In the phenol group, only 53% patients achieved healing after 1 application. The median healing time was shorter in the platelet-rich plasma group: 6 (4-14) vs 10 (5-42) days (p < 0.001). The mean difference in healing was 5.8 days (95% CI, 4.27-7.38). After a mean follow-up of 43.1 months, there was a 4% recurrence rate in the platelet-rich plasma group in comparison with a 12% recurrence rate in the phenol group (95% CI, 0.024-0.251).

Abstract

As a chronic condition, pilonidal disease affects a young population, and recovery after the surgical procedures performed to treat this condition require time off from work. Therefore, the search for an ideal treatment is still ongoing. The aim of this study was to compare early and late results of 2 minimally invasive treatment options used to treat pilonidal disease. This study was designed as a parallel group randomized clinical trial. This study took place at an outpatient clinic in Turkey. Patients with pilonidal disease were evaluated for the study and were enrolled if they met the inclusion criteria and gave informed consent. Patients in the platelet-rich plasma group were treated using curettage + platelet-rich plasma gel. Patients in the phenol group were treated by using curettage + crystallized phenol. The primary study end point was the time to achieve healing; the secondary outcome was recurrence rate. In the platelet-rich plasma group, 96% of patients achieved healing after 1 application. In the phenol group, only 53% patients achieved healing after 1 application. The median healing time was shorter in the platelet-rich plasma group: 6 (4-14) vs 10 (5-42) days (p < 0.001). The mean difference in healing was 5.8 days (95% CI, 4.27-7.38). After a mean follow-up of 43.1 months, there was a 4% recurrence rate in the platelet-rich plasma group in comparison with a 12% recurrence rate in the phenol group (95% CI, 0.024-0.251). Despite the randomized prospective nature of the study, neither the patients nor the investigators were blinded. The curettage + platelet-rich plasma method can be safely applied with an improved healing time, low recurrence rate, and minimal time off work.

ANTECEDENTES:Como condici&#xf3;n cr&#xf3;nica, la enfermedad pilonidal afecta a una poblaci&#xf3;n joven y los procedimientos quir&#xfa;rgicos que se realizan para tratar esta condici&#xf3;n requieren un tiempo de recuperaci&#xf3;n con baja laboral. Por lo tanto, la b&#xfa;squeda del tratamiento ideal a&#xfa;n est&#xe1; en curso.OBJETIVO:El objetivo de este estudio es comparar los resultados tempranos y tard&#xed;os de dos opciones de tratamiento m&#xed;nimamente invasivos utilizados para tratar la enfermedad pilonidal.DISE&#xd1;O:Este estudio est&#xe1; dise&#xf1;ado como un ensayo cl&#xed;nico aleatorizado de dos grupos paralelos.ENTORNO CL&#xcd;NICO:El estudio consta de dos grupos: curetaje + plasma rico en plaquetas y curetaje + fenol.PACIENTES:Los pacientes con enfermedad pilonidal fueron evaluados para el estudio y se inscribieron si cumpl&#xed;an con los criterios de inclusi&#xf3;n y dieron su consentimiento informado.INTERVENCIONES:Los pacientes del grupo de plasma rico en plaquetas fueron tratados con curetaje + gel de plasma rico en plaquetas. En el grupo de fenol, los pacientes fueron tratados con curetaje + fenol cristalizado.PRINCIPALES MEDIDAS DE RESULTADO: El principal criterio de valoraci&#xf3;n del estudio fue el tiempo para lograr la curaci&#xf3;n; el resultado secundario fue la tasa de recurrencia.RESULTADOS:En el grupo de plasma rico en plaquetas, el 96% de los casos logr&#xf3; la curaci&#xf3;n despu&#xe9;s de una aplicaci&#xf3;n. En el grupo de fenol, solo el 53% de los casos lograron la curaci&#xf3;n despu&#xe9;s de una aplicaci&#xf3;n. La mediana del tiempo de curaci&#xf3;n fue m&#xe1;s corta en el grupo de plasma rico en plaquetas; 6 (4-14) vs 10 (5-42) d&#xed;as (p < 0,001). La diferencia media en la curaci&#xf3;n fue de 5,8 d&#xed;as (IC del 95%: 4,27-7,38). Despu&#xe9;s de un seguimiento medio de 43,1 meses, hubo una tasa de recurrencia del 4% en el grupo de plasma rico en plaquetas en comparaci&#xf3;n con una tasa de recurrencia del 12% en el grupo de fenol (IC del 95%: 0.024-0.251).LIMITACIONES:A pesar de la naturaleza prospectiva aleatorizada del estudio, ni los pacientes ni los investigadores fueron cegados.CONCLUSIONES:El m&#xe9;todo de legrado + plasma rico en plaquetas se puede aplicar de forma segura con un mejor tiempo de curaci&#xf3;n, una tasa de recurrencia baja y un tiempo de baja laboral m&#xed;nimo.
