Tratamiento quirúrgico de la enfermedad pilonidal sacrocoxígea. Experiencia de un centro en los últimos 4 años

Objetivo: Evaluar los resultados a largo plazo en el tratamiento quirúrgico de la enfermedad pilonidal sacrocoxígea (EPS), comparando las diferentes técnicas quirúrgicas utilizadas, complicaciones, tiempo de cicatrización y recidiva. Material y Método: Estudio trasversal retrospectivo. Se revisaron las fichas de los pacientes intervenidos por EPS entre enero 2017 hasta agosto 2021. Para el seguimiento se obtuvo la información desde los registros de los controles periódicos en nuestro centro y aquellos que no continuaron con estos controles se contactaron telefónicamente. Resultados: Se recopilaron 309 casos, con una media de seguimiento de 15,6 meses. Las técnicas más utilizadas para la fase crónica de EPS fueron marsupialización y Karydakis, con tiempo de cicatrización completa de 54,5 y 18,2 días, respectivamente. La presencia de complicaciones prolongó el tiempo de cicatrización en 46,5 días en Karydakis, con mínimo impacto en marsupialización. La tasa de recidiva fue menor en Karydakis y en etapa aguda cuando se realiza destechamiento y legrado. La profilaxis antibiótica no afectó el riesgo de complicaciones postoperatorias. Discusión: El desarrollo de complicaciones postoperatorias tiene mayor impacto en la cicatrización de la técnica cerrada que en la abierta, siendo esta última más tolerante en cuanto a la cicatrización frente a complicaciones. Conclusión: La intervención con técnica de Karydakis logra la cicatrización de la herida operatorio en menor tiempo que la marsupialización, sin embargo, al desarrollar complicaciones, este tiempo aumenta 3,5 veces más. La recurrencia fue menor en Karydakis. En absceso se recomienda el desteche y legrado por sobre el drenaje exclusivo

Aim: To evaluate long-term results in the surgical treatment of sacrococcygeal pilonidal disease (SPD) comparing the different surgical techniques used, complications, healing time and recurrence. Material and Method: Retrospective cross-sectional study. The files of the patients operated on for EPS between January 2017 and August 2021 were reviewed. For follow-up, information was obtained from the records of the periodic controls in our center; those who did not continue with these controls were contacted by telephone. Results: 309 cases were collected, with a mean follow-up of 15.6 months. The most used techniques for the chronic phase of EPS were marsupialization and Karydakis, achieving complete wound healing in 54.5 and 18.2 days, respectively. The presence of complications prolonged the healing time by 46.5 days in Karydakis, with minimal impact on marsupialization. The recurrence rate was lower in Karydakis and in the acute stage when unroofing and curettage were performed. Antibiotic prophylaxis did not increase the risk of postoperative complications. Discussion: The development of postoperative complications has a greater impact on the healing of the closed technique than in the open technique, the last one seems to be more tolerant in terms of healing in the presence of complications. Conclusion: The intervention with the Karydakis technique achieves healing of the surgical wound in less time than marsupialization, however, when complications develop, this time increases 3.5 times more. Recurrence was lower in Karydakis. In abscess weaning and curettage is recommended over the exclusive drainage.

Aim: To characterize the preferences and frequency of surgical techniques for the resolution of pilonidal disease (PSD) in colorectal surgeons of Latin America. Materials and Method: Cross-sectional descriptive and analytical study using an electronic survey validated by expert peers. Distributed among colorectal surgeons in Latin America. Surgeons who were not subspecialists in colorectal surgery were excluded. Results: 372 responses were obtained from subspecialist surgeons in colorectal surgery from 15 Latin American countries, with a mean of 18.9 ± 12.5 years as subspecialists. 66.7% use open techniques for chronic PSD, the most used techniques: marsupialization (31.5%), unroofing (27.7%) and resection with the Karydakis technique (17.7%), Limberg flap (6, 1%), Bascom (5.4%), Z or VY plasties (4%), McFee (3.8%) and Epsit (3.8%). The most used intervention for the resolution of acute PSD is drainage under formal anesthesia with curettage and/or marsupialization (51.1%). 45.3% of surgeons change techniques during their career. Discussion: Due to the wide distribution and representativeness of the respondents, it was possible to capture the preference in a realistic way about the management of the PSD by the subspecialists of the continent, contributing with information with which there is no precedent. Conclusion: Open techniques are preferred for the resolution of chronic PSD, marsupialization, unroofing and Karydakis were used the most. The change of surgical technique within subspecialists is frequent, there is a relationship between preferring open techniques to the extent that surgeons have more years of experience.

Surgical outcome of modified Karydakis flap and modified Limberg flab in the management of sacroccygeal pilonidal disease: a comparative study

Introduction: Sacrococcygeal pilonidal disease (SPD) is a chronic suppurative condition of the sacrococcygeal region causing chronic sinus tract or cyst. It is an acquired complex disease more common in young adult males, causing considerable morbidity and long periods of interruption in work or education. From simple conservative techniques to complex flap reconstruction, many debatable treatment options are offered; however clear dynamics toward the widespread use of minimally invasive methods and off-midline flap reconstruction are suggested in all guidelines, which recommend the Karydakis and Limberg flap modification. The plethora of literature compares procedures for identification of a single best treatment approach, which has proven to be difficult. The surgical outcome of both techniques is compared in the present study. Objective: To compare the surgical outcomes of the modified Karydakis flap (MKF) versus the modified Limberg flap (MLF) in SPD. Materials and Methods: The present study was conducted at the general surgery department on SPD patients who were ≥18 years old. A total of 67 participants were included after obtaining the informed consent, with group A comprising 33 patients undergoing the MLF procedure and group B comprising 34 patients undergoing the MKF procedure. Results: The mean patient age was 28.85 (range, 18-44) years old. For the MKF and MLF methods, the average operating duration was 32.5 (range, 25-40) and 54.5 (range, 45-65) minutes, respectively. The MKF approach was found to significantly improve pain score, mean sitting painless time, return to normal activity, wound healing time, and patient satisfaction. Conclusion: Comparative outcomes were seen between both MKF and MLF; however, our findings show that MKF is a more favourable method than MLF with superior outcomes. (AU)

Modified Karydakis procedure for uncomplicated pilonidal sinus

Background: Pilonidal sinus disease is a chronic infection of the natal cleft commonly affecting young adults. Out of the standard operative techniques, the Karydakis procedure is a relatively simple procedure associated with low rates of wound complications and recurrence. In this study we present a modified version of the Karydakis procedure to treat less extensive disease, which enables better skin closure without cavitation and tension.Methods: Patients with uncomplicated pilonidal sinus who presented to our centre during the period from April 2015 to March 2019 were prospectively enrolled. Patients with recurrent or complex sinus disease were excluded. In those enrolled, our modified Karydakis procedure was performed. In this method, after excision a flap of skin and subcutaneous tissue was raised to one side and sutured across the midline by advancement in layers.Results: 34 patients underwent our modified Karydakis procedure. 91% (31/34) of patients had uncomplicated recovery and could return to work after two weeks. There were minimal post-operative complications, in the form of erythema around the wound (8.8%), wound discharge (5.9%), seroma (5.9%) and infection (2.9%). No patient developed wound dehiscence or flap necrosis. There were excellent cosmetic results and no recurrence at one year post-surgery.Conclusions: Our modification of the Karydakis procedure is a simple and effective surgery for the management of uncomplicated pilonidal sinus disease which achieves good results.

Effectiveness of Limberg and Karydakis flap in recurrent pilonidal sinus disease

OBJECTIVE: Sacrococcygeal pilonidal sinus is common in young men and may recur over time after surgery. We investigated whether a factor exists that can aid in the determination of the preferred technique between the early Limberg flap and Karydakis flap techniques for treating recurrent pilonidal sinus. MATERIALS AND METHODS: This prospective and randomized study enrolled 71 patients with recurrent pilonidal sinus in whom the Limberg flap or Karydakis flap techniques were applied for reconstruction after excision. Patients were divided into two groups as follows: 37 patients were treated with the Limberg flap technique and 34 patients were treated with the Karydakis flap technique. Fluid collection, wound infection, flap edema, hematoma, partial wound separation, return to daily activities, pain score, complete healing time, painless seating and patient satisfaction were compared between the groups. ClinicalTrial.gov: NCT02287935. RESULTS: The development rates of total fluid collection, wound infection, flap edema, hematoma, and partial wound separation were 9.8%, 16%, 7%, 15% and 4.2%, respectively; total flap necrosis was not observed in any patient (p<0.001). During the average follow-up of 28 months, no patients (0%) developed recurrent disease. The two groups differed with respect to early surgical complications (p<0.001). CONCLUSION: In this study, use of the Limberg flap was associated with lower complication rates, shorter length of hospital stay, early return to work, low pain score, high patient satisfaction and better complete healing duration. Therefore, we recommend the Limberg flap for treatment of recurrent pilonidal sinus. .

Resultados a corto y largo plazo con la técnica de Karydakis para la enfermedad pilonidal sacrocoxígea / Short-and long-term results with Karydaki’s technique for sacrococcygeal pilonidal disease

Introduction: Sacrococcygeal pilonidal cyst or sinus is a common condition in young people. There is still discussion about which of the many existing techniques is best suited to resolve this condition. Objective: To analyze the short-and long-term use of Karydaki's technique in our Hospital. Material and Methods: We analyzed prospective protocols from patients with pilonidal cyst with Karydaki's technique from June 2005 to August 2010. Clinical and telephonic follow-up was done to all patients and a satisfaction survey done to a random sample of the series. Results: We analyzed 62 patients with mean age of 24.5 years (15-45), being 33 men (53 percent). Cysts were previously relapsed in 20.9 percent of cases. The average hospital stay was 2.5 days (1-3). Early complications occurred in 14.3 percent of patients being the most common seroma in 8 percent and dehiscence in 6.4 percent. At a mean follow up of 38 months (12-62), relapse occurred in two patients (3.2 percent), one at 6 months and the other at 3 years, being resolved one by a new Karydaki's technique and the other with marsupialization. Among the group surveyed for satisfaction, 75 percent found the technique satisfactory or very satisfactory in terms of aesthetics and 95 percent would recommend this technique. Conclusions: Karydaki's operation achieves with a simple and aesthetic technic a low recurrence and morbidity and a complete recovery after 15 days in most patients.

Background: Asymmetrical closed techniques have comparative benefits for the treatment of sacrococcygeal pilonidal disease. Aim: To assess the results of Karydakis asymmetrical excision, performed on an ambulatory basis. Patients and Methods: Prospective evaluation of 29 females and 21 males aged 15 to 44 years operated using Karydakis procedure on an ambulatory basis. Results: The body mass Index of patients fluctuated between 19 and 47 kg/m². Thirty eight percent were overweight and 28 percent were obese. Sixty two percent were hirsute. The form of presentation of the disease was the spontaneous or surgical drainage of an abscess with chronic suppuration in 92 percent of cases. Surgical time fluctuated between 25 and 45 minutes. All patients were discharged four to six hours after the procedure. There were no re-operations and the rate of complications was 10 percent. Ninety percent of patients did not have a local complications and a complete healing was achieved three weeks after the operation. After a follow up of 3 to 65 months, no relapses have been observed. Conclusions: Karydakis procedure, performed on an ambulatory basis, is safe, feasible and has excellent results.

Antecedentes: Las técnicas cerradas asimétricas tienen ventajas comparativas en el manejo de la enfermedad pilonidal sacrococcígea (EPSC). El objetivo de este estudio es evaluar los resultados de la resección asimétrica de Karydakis programada como cirugía mayor ambulatoria. Pacientes y Método: Estudio prospectivo de 100 pacientes intervenidos en forma electiva desde abril de 2001; 84 con la técnica de Karydakis y, de ellos, 50 pacientes en forma ambulatoria. Se utilizó la técnica clásica descrita por el autor, con pequeñas modificaciones que intentan alejar la cicatriz de la línea media. Resultados: Se trata de 29 mujeres y 21 hombres, con un promedio de edad de 21,2 años (extremos 15-44). El IMC promedio fue de 27,28 (extremos 19-47), sin diferencias estadísticas según el género. El 38 por ciento de los pacientes tenían sobrepeso y el 28 por ciento eran obesos. El 62 por ciento de los pacientes fue catalogado como hirsutos, con claro predominio de los pacientes varones (p = 0,012). La forma clínica de presentación fue el drenaje espontáneo o quirúrgico de un absceso con supuración crónica intermitente en el 92 por ciento de los casos. El tiempo operatorio promedio de 34 minutos (extremos 25-45). Todos los pacientes fueron dados de alta entre 4 y 6 horas luego del procedimiento, no hubo reoperaciones y la morbilidad global fue 10 por ciento. El 90 por ciento de los pacientes no tuvo complicaciones locales logrando una cicatrización completa antes de 3 semanas de la intervención. El seguimiento promedio de la serie es 30 meses (extremos 3-65) sin casos de recidiva (1,19 por ciento - 1/84) en la serie global con un período de observación promedio de 49 meses (extremos 6-88). Conclusión: La operación de Karydakis realizada en forma ambulatoria es factible, segura y muestra excelentes resultados en tiempo de cicatrización, morbilidad y recidiva.
