Pharyngeal mucosal closure in total laryngectomy: comparison between vertical and T-shaped closure.

Objective: The objective of this study was to compare the outcomes vertical and T-shaped pharyngoplasty closure techniques after total laryngectomy (TL) and to evaluate the factors associated with the development of pharyngocutaneous fistula. Materials and methods: We performed a retrospective study that included patients with a histopathological diagnosis of laryngeal cancer that underwent TL between 2009 and 2021. Results: Fifty-seven patients were included in the study. A total of 14 patients underwent a vertical closure of the neopharynx (24.6%), while 43 patients underwent a T-shaped closure (74.4%). Pharyngocutaneous fistula was the most common complication, observed in 40.4% of cases (n = 23). No difference in the rate of complications was observed between groups, with the exception of tracheal dehiscence which was reduced in patients with T-shaped closure (n = 2, 4.7% vs. n = 5, 35.7%, p = 0.002). Diabetes mellitus was more frequently observed in patients withthe development of pharyngocutaneous fistula (n = 7, 30.4% vs. n = 3, 8.8%, p = 0.03). Conclusions: Although complicationswere lower in the T-shaped closure group, we could not establish the superiority of either technique.

Objetivo: Evaluar los desenlaces de la técnica vertical en comparación con la técnica en T para el cierre de faringoplastia posterior a una laringectomía total, y evaluar los factores asociados con el desarrollo de fístula faringocutánea. Método: Estudio retrospectivo de pacientes con diagnóstico de cancer de laringe a quienes se realizó laringectomía total como tratamiento, de 2009 a 2021. Resultados: Se incluyeron 57 pacientes. A 14 (24.6%) se les realizó una faringoplastia con cierre en T y a 43 (74.4%) un cierre vertical. La fístula faringocutánea fue la complicación más frecuente, presente en el 40.4% de los casos (n = 23). No se observaron diferencias en el desarrollo de complicaciones entre grupos, con excepción de la dehiscencia traqueal, la cual fue menos frecuente en el grupo de cierre en T (n = 2, 4.7% vs. n = 5, 35.7%; p = 0.002). La diabetes mellitus se asoció con el desarrollo de fístula faringocutánea (n = 7, 30.4% vs. n = 3, 8.8%; p = 0.03). Conclusiones: Aunque se observó una tendencia a una disminución de las complicaciones en el grupo de cierre en T, no se encontró superioridad de una técnica sobre otra.

[Spontaneous cholecysto-cutaneous fistula: about two cases]. / Fístula colecisto-cutánea espontánea: a propósito de dos casos.

Cholecysto-cutaneous fistula (CCF) is a rare complication of untreated biliary pathology, with fewer than 100 cases documented in the literature. Most are secondary to bacterial infection, although it has also been described in gallbladder adenocarcinoma and post trauma. Its clinical presentation is variable, being able to present systemic affection, and its most frequent external drainage site is in the right hypochondrium. Due to the low incidence of this pathology, and the variety of forms of presentation, its management does not have, to date, standardized bases. We present two cases of patients who consulted in the emergency room at the Hospital Nacional de Clínicas for presenting cholecysto-cutaneous fistula. The treatment of both was surgical.

La fístula colecisto-cutáneas (FCC) es una rara complicación de la patología biliar no tratada, habiendo menos de 100 casos documentados en la literatura. La mayoría son secundarias a infección bacteriana, aunque también fue descripta en el adenocarcinoma de vesícula y posterior a traumatismo. Su presentación clínica es variable, pudiendo presentar afección sistémica, y su sitio más frecuente de drenaje externo es en hipocondrio derecho. Debido a la baja incidencia de esta afección, y a la variedad de formas de presentación, su manejo no tiene hasta el momento bases estandarizadas. Presentamos dos casos de pacientes que consultaron por guardia de urgencias en el Hospital Nacional de Clínicas por presentar fistula colecisto-cutánea. El tratamiento de ambos fue quirúrgico.

Multiple cutaneous fistula after titanium dental implant: A case report.

BACKGROUND: Dental implants allow functional and aesthetic reestablishment. Titanium (Ti) implants emerge as the preferred choice because Ti is considered an inert material, highly resistant to corrosion. However, virtually no material can be considered universally biocompatible and this includes titanium. PURPOSE: To report an unusual presentation of inflammatory reaction after a Ti dental implant. MATERIALS AND METHODS: The patient presented to a dermatology clinic to evaluate lesions on her face. She reported the placement of dental implants 2 years earlier, one of which evolved with inflammatory signs and instability a few days after the procedure. As anti-inflammatory and antibiotic therapy were fruitless, after 3 months the implant was removed, but the inflammation persisted. On physical examination, painful erythematous-papule-nodular lesions were found on the left mandibular and submandibular region. RESULTS: Culture tests for microorganisms were negative and histopathological examination revealed a chronic fistula with a foreign body reaction. Using X-ray fluorescence, Ti particles were found along the fistula wall. CONCLUSIONS: Professionals should be aware of complications arising from dental implants, including Ti implants. Detailed anamnesis and laboratory investigation can assure diagnosis for specific therapeutic approaches.

Salvage total laryngectomy: is a flap necessary? / Laringectomia total de resgate: o uso de retalho é necessário?

Abstract Introduction: Pharyngocutaneous fistula is the most significant complication after salvage total laryngectomy in patients who have received previous treatment with radiotherapy with or without chemotherapy. Objective: Our purpose is to review the fistula rate in radiated patients undergoing salvage total laryngectomy, to determine if the use of pectoralis major flap interposition reduces the incidence and duration of fistula and to examine other risk factors. Methods: We made a retrospective review of patients undergoing salvage total laryngectomy for exclusively larynx cancer after failure of primary curative radiotherapy between 2000 and 2017. General data from patients, risk factors and other complications were analyzed. Results: We identified 27 patients whose mean age was 66.4 years, mainly male (92.5%). The primary closure group without pectoralis major flap included 14 patients, and the group with pectoralis major flap closure included 13 patients. Pharyngocutaneous fistula was present in 15 patients (55.5%). Global pharyngocutaneous fistula rate was higher in the group of patients without pectoralis major flap comparing with those were the flap was interposed (78.6% versus 30.8%, p = 0.047). Also the pharyngocutaneous fistulas which need to be repaired with surgery (64.3% versus 7.7%, p = 0.03) and large pharyngostomes (64.3% versus 0%, p = 0.0004) were present in a higher rate in the group closed primary without pectoralis major flap. We did not find other risk factors with statistical significance. Oral diet initiation (84 days versus 21.5 days, p = 0.039) and the duration of hospitalization (98.3 days versus 27.2 days, p = 0.0041) were much lower in patients with a preventive pectoralis major flap. Two patients died as a consequence of complications of large pharyngostomes. Conclusions: Prophylactic pectoralis major flap reduced the incidence, severity and duration of fistula and should be considered during salvage total laryngectomy.

Resumo Introdução: A fístula faringocutânea é a complicação mais significativa após laringectomia total de resgate em pacientes que receberam tratamento prévio com radioterapia com ou sem quimioterapia. Objetivo: Revisar a taxa de fístula em pacientes irradiados submetidos a laringectomia total de resgate, para determinar se o uso de interposição de retalho do peitoral maior reduz a incidência e a duração da fístula e examinar outros fatores de risco. Método: Fizemos uma revisão retrospectiva de pacientes submetidos à laringectomia total de resgate para câncer exclusivamente laríngeo após falha da radioterapia curativa primária entre 2000 e 2017. Dados gerais dos pacientes, fatores de risco e outras complicações foram analisados. Resultados: Foram identificados 27 pacientes com média de 66,4 anos, principalmente do sexo masculino (92,5%). O grupo de fechamento primário sem retalho de peitoral maior incluiu 14 pacientes e o grupo de fechamento com retalho de peitoral maior incluiu 13 pacientes. Fístula faringocutânea esteve presente em 15 pacientes (55,5%). A taxa global de fístula faringocutânea foi maior no grupo de pacientes sem retalho de peitoral maior em comparação com aqueles que receberam o retalho (78,6% vs. 30,8%, p = 0,047). Além disso, as fístulas faringocutâneas que precisaram ser reparadas através de cirurgia (64,3% vs. 7,7%, p = 0,03) e grandes faringostomias (64,3% vs. 0%, p = 0,0004) apresentaram uma taxa mais alta no grupo fechado primariamente sem retalho do peitoral maior. Não encontramos outros fatores de risco com significância estatística. O início da dieta oral (84 dias vs. 21,5 dias, p = 0,039) e a duração da internação (98,3 dias vs. 27,2 dias, p = 0,0041) foram muito menores nos pacientes com uso preventivo do retalho do peitoral maior. Dois pacientes morreram em consequência de complicações de grandes faringostomias. Conclusões: O uso profilático do retalho do peitoral maior reduziu a incidência, a gravidade e a duração da fístula e deve ser considerado durante a laringectomia total de resgate.

Effect of Preoperative Administration of Oral Arginine and Glutamine in Patients with Enterocutaneous Fistula Submitted to Definitive Surgery: a Prospective Randomized Trial.

BACKGROUND: The use of glutamine and arginine has shown several advantages in postoperative outcomes in patients after gastrointestinal surgery. We determined the effects of its use in patients with enterocutaneous fistula after operative treatment. PATIENTS AND METHODS: Forty patients with enterocutaneous fistula were randomly assigned to one of two groups. The control group received the standard medical care while the patients of the experimental group were supplemented with enteral administration of 4.5 g of arginine and 10 g of glutamine per day for 7 days prior to the surgery. The primary outcome variable was the recurrence of the fistula and the secondary outcomes were preoperative and postoperative serum concentrations of interleukin 6 and C-reactive protein and postoperative infectious complications. RESULTS: Twenty patients were assigned to each group. The fistula recurred in two patients (10%) of the experimental group and in nine patients (45%) of the control group (P < 0.001). We found a total of 13 infectious complications in six patients of the control group (all with fistula recurrence) and none in the experimental group. Mean preoperative serum concentrations of interleukin 6 and C-reactive protein were lower in patients from the experimental group. In addition, these levels were lower in patients who had recurrence if compared to patients that did not recur. CONCLUSION: Preoperative administration of oral arginine and glutamine could be valuable in the postoperative recovery of patients with enterocutaneous fistulas submitted to definitive surgery.

[Disseminated infection caused by the bacillus Calmette-Guérin vaccine and SARS-CoV-2 coinfection in a patient with IL-12 receptor ß1 subunit deficiency]. / Infección diseminada por vacuna con bacilo de Calmette-Guérin y coinfección por SARS-CoV-2 en paciente con deficiencia de la subunidad ß1 del receptor de IL-12.

BACKGROUND: Inborn errors of immunity manifest with a greater susceptibility to infections, autoimmunity, autoinflammatory diseases, allergies, or malignancies. One of these is the mendelian susceptibility to mycobacterial disease. The most frequent etiology is the complete autosomal recessive deficiency of the ß1 subunit of the interleukin 12 receptor. CASE REPORT: A female patient who, by the age of six months, started with a nodular lesion in the right shoulder and ipsilateral axillary adenitis after the bacillus Calmette-Guérin vaccine was applied. Later, she developed a cutaneous fistula in the anterior thorax, the inframammary region, and chronic recidivant suppurative lymphadenitis. A disseminated infection caused by Mycobacterium bovis was diagnosed, therefore, individualized pharmacological treatment was required due to failure with the primary treatment. The patient was diagnosed with deficiency in the ß1 subunit of the interleukin 12 receptor at age six. During her last hospitalization, she presented fever, cough, and tachypnea, and SARS-CoV-2 was detected by quantitative polymerase chain reaction. The patient has had a favorable evolution. CONCLUSION: In patients with disseminated infections caused by bacillus Calmette-Guérin vaccination or by environmental mycobacteria, there should be suspicion of an inborn error of immunity and the patient should be referred to a third level hospital for an early immunological assessment.

Antecedentes: Los errores innatos de la inmunidad se manifiestan con una mayor susceptibilidad a infecciones, autoinmunidad, enfermedades autoinflamatorias, alergia o malignidad. Uno de estos es la susceptibilidad mendeliana a infecciones micobacterianas. La etiología más frecuente es la deficiencia completa autosómica recesiva de la subunidad ß1 del receptor de interleucina 12. Caso clínico: Paciente que comenzó a los seis meses de edad con una lesión nodular en hombro derecho y adenitis axilar ipsolateral posterior a la vacuna con bacilo de Calmette-Guérin. Posteriormente desarrolló una fistula cutánea en tórax anterior, región inframamaria y linfadenitis supurativa crónica recidivante. Se diagnosticó infección diseminada por Mycobacterium bovis, por lo que requirió tratamiento farmacológico individualizado debido al fracaso con el tratamiento primario. La paciente fue diagnosticada con deficiencia de la subunidad ß1 del receptor de interleucina 12 a los seis años. Durante su última hospitalización presentó fiebre, tos y taquipnea, detectándose SARS-CoV-2 por reacción en cadena de la polimerasa cuantitativa. La paciente evolucionó favorablemente. Conclusión: En los pacientes con infecciones diseminadas por la vacuna con bacilo de Calmette-Guérin o micobacterias ambientales, debe sospecharse un error innato de la inmunidad y derivarlos a tercer nivel de atención para la evaluación inmunológica temprana.

Repair of post-laryngectomy pharyngocutaneous fistulas using a pectoralis major flap / Reparo de fístulas faringocutâneas pós-laringectomia utilizando retalho do músculo peitoral maior

Abstract Introduction: The pectoralis major flap is a reconstructive option to consider in the treatment of pharyngocutaneous fistula after a total laryngectomy. There are not large studies assessing variables related to pharyngocutaneous fistula recurrence after removal of the larynx. Our objectives were to review the results obtained with this type of treatment when pharyngocutaneous fistula appears in laryngectomized patients, and to evaluate variables related to the results. Methods: We retrospectively reviewed our results using either a myocutaneous or fasciomuscular pectoralis major flap to repair pharyngocutaneous fistula in 50 patients. Results: There were no cases of flap necrosis. Oral intake after fistula repair with a pectoralis major flap was restored in 94% of cases. Fistula recurrence occurred in 22 cases (44%), and it was associated with a lengthening of the hospital stay. Performing the flap as an emergency procedure was associated with a significantly higher risk of fistula recurrence. Hospital stay was significantly shorter when a salivary tube was placed. Conclusions: The pectoralis major flap is a useful approach to repair pharyngocutaneous fistula. Placing salivary tubes during fistula repair significantly reduces hospital stay and complication severity in case of pharyngocutaneous fistula recurrence.

Resumo Introdução: O retalho do músculo peitoral maior é uma opção a ser considerada no fechamento de fístula faringocutânea pós-laringectomia total. Não há grandes estudos que avaliem as variáveis relacionadas à recorrência da fístula faringocutânea após esse procedimento. Nossos objetivos foram avaliar os resultados obtidos com esse tipo de tratamento em pacientes laringectomizados com fístula faringocutânea e as variáveis relacionadas aos resultados. Método: Revisamos retrospectivamente os nossos resultados em 50 pacientes nos quais um retalho miocutâneo ou fasciomuscular do músculo peitoral maior foram utilizados para reparar a fístula faringocutânea. Resultados: Não houve casos de necrose de retalho. Após o reparo da fístula com um retalho do músculo peitoral maior, a ingestão oral foi restaurada em 94% dos casos. Houve recorrência da fístula em 22 casos (44%), a qual foi associada à duração da hospitalização. O uso do retalho como procedimento de emergência foi associado a um risco significativamente maior de recorrência da fístula. A permanência hospitalar foi significativamente menor quando utilizado um tubo de derivação salivar. Conclusões: O uso do retalho do músculo peitoral maior é uma abordagem útil para reparar a fístula faringocutânea. A colocação de tubos de derivação salivar durante o reparo da fístula reduz significativamente o tempo de hospitalização e a gravidade das complicações em caso de recorrência da fístula faringocutânea.

Efficacy of the cardiac septal occluder in the treatment of post-bariatric surgery leaks and fistulas.

BACKGROUND: Endoscopy has evolved to become first-line therapy for the treatment of post-bariatric leaks; however, many sessions are often required with variable success rates. Due to these limitations, the use of the cardiac septal defect occluder (CSDO) has recently been reported in this population. METHODS: The study population was a multicenter retrospective series of patients with post-bariatric surgical leaks who underwent treatment with CSDO placement. Data on the type of surgery, previous treatment details, fistula dimensions, success rate, and adverse events were collected. Leaks were grouped according to the International Sleeve Gastrectomy Expert Panel Consensus. Outcomes included technical and clinical success and safety of the CSDO. Regression analysis was performed to determine the predictors of response. RESULTS: Forty-three patients with leaks were included (31 sleeve gastrectomy and 12 Roux-en-Y gastric bypass). They were divided into acute (n = 3), early (n = 5), late (n = 23), and chronic (n = 12). Forty patients had failed previous endoscopic treatment and 3 patients had CSDO as the primary treatment. Median follow-up was 34 weeks. Technical success was achieved in all patients and clinical success in 39 patients (90.7%). All chronic, late, and early leaks were successfully closed, except one undrained late leak. The 5 patients with early leaks had an initial satisfactory response, but within 30 days, drainage recurred. The CSDOs were removed and replaced with larger-diameter devices leading to permanent defect closure. Acute leaks were not successfully closed in all 3 patients. Regression analysis showed that chronicity and previous treatment were associated with fistula closure; success rates for late/chronic leaks versus acute/early leaks were 97.1% and 62.5%, respectively (P = .0023). CONCLUSION: This observational study found that the CSDO had a high efficacy rate in patients with non-acute leaks, with no adverse events. All early, late, and chronic leaks were successfully closed, except for one undrained late leak. However, early leaks required a second placement of a larger CSDO in all cases. These results suggest that the CSDO should be considered for non-acute fistula and that traditional closure methods are likely preferred in the acute and early settings.

Cáncer de colon con infiltración a pared abdominal: un reto diagnóstico / Colonic cancer with infiltration to the abdominal wall: a diagnostic challenge

Se presenta el caso de una paciente mujer de 53 años procedente de Piura con un tiempo de enfermedad de 20 meses, caracterizado por dolor en sitio de herida quirúrgica por colecistectomía abierta realizada hace 3 años, asociado a presencia de una masa en dicha zona, posteriormente se absceda y comienza a drenar secreción alimentaria. Los estudios de imágenes revelaron una masa dependiente de colon transverso en contacto con estómago y pared abdominal que presentaba fistulas hacia piel. Dicha masa fue extraída durante la cirugía con resultado anatomopatológico de adenocarcinoma mucinoso de colon. El caso representó un reto diagnóstico para el equipo médico y en vista de las diversas manifestaciones clínicas del cáncer de colon, sugerimos mantenerlo presente como diagnóstico diferencial en cuadros de absceso de pared abdominal y fistulizaciones entéricas.

We present the case of a 53-year-old woman with a time of illness of 20 months, characterized by pain at the site of surgical intervention for opened cholecystectomy 3 years ago, associated with a presence of a mass in said area, with the following abscess formation and fistulization of food content. Imaging studies revealed a mass dependent of the transverse colon, in contact with stomach and abdominal wall and presenting fistulas to the skin. Said mass was extracted during surgery with anatomopathological result of mucinous colon adenocarcinoma. The case represented a diagnostic challenge for the medical team and in view of the variaty of clinical manifestations of colonic cancer, we suggest that it should be consider as a differential diagnosis in cases of abdominal wall abscess and enteric fistulas.

Penile and scrotal lymphedema associated with hidradenitis suppurativa: Case report and review of surgical options. / Linfedema penoescrotal secundario a hidrosadenitis supurativa: a propósito de un caso, revisión de las opciones quirúrgicas

Lymphedema is the result of an alteration of the lymphatic drainage, and its most common worldwide cause is filariasis. In our practice usually is associated to neoplasic, inflammatory and granulomatous processes, radiotherapy, hydroelectrolytic disbalances, and idiopathic. It can affect any part of the body, including the penis and scrotum. The genital lymphedema is a rare presentation, it corresponds to 0.6% of lymphedema. However, causes serious functional, social and emotional limitations for the patient. Too often have pain, recurrent infections, sexual dysfunction, cosmetic deformity, sometimes it limits mobility and ambulation. Although there are several treatment options, both medical and surgical, it has not been found ideal for this disease. We present a 43 years old patient with penoscrotal lymphedema due to hidradenitis suppurativa, it limits his normal activity. The patient was referred to our center after unsuccessful medical treatment (doxycycline and clindamycin cycles). Surgical treatment consisted of total excision of the skin and subcutaneous tissue to Buck's fascia. Split thickness skin grafts were used to cover the defect. The result was satisfactory both functionally and aesthetically.

El linfedema es producto de una alteración en el drenaje linfático, y su causa más frecuente en todo el mundo es la filariasis. En nuestro medio suele encontrarse asociada a procesos neoplásicos, inflamatorios, granulomatosos, secuelas por radioterapia, desequilibrios hidroelectrolíticos y procesos idiopáticos. Puede afectar a cualquier parte del cuerpo, incluyendo el pene y el escroto. El linfedema genital es una presentación infrecuente, que corresponde al 0.6% de los linfedemas. No obstante, causa graves limitaciones funcionales, sociales y emocionales para el paciente. Con mucha frecuencia se presentan dolor, infecciones recurrentes, disfunción sexual y deformidad estética, llegando incluso a limitar la movilidad y la deambulación. Aunque existen varias opciones de tratamiento, tanto médico como quirúrgico, no se ha encontrado el ideal para esta enfermedad. Presentamos el caso de un paciente de 43 años afecto de hidrosadenitis axilar e inguinal que padece linfedema penoescrotal grave que limita seriamente su actividad habitual. El paciente fue remitido a nuestro centro tras el fracaso del tratamiento con antibióticos (ciclos de doxiciclina y clindamicina). El tratamiento quirúrgico consistió en la resección de piel y tejido celular subcutáneo hasta fascia de Buck y cobertura con injertos de piel. El resultado final fue adecuado desde un punto de vista tanto funcional como estético.

Tubocutaneous Fistula due to Endometriosis - A Differential Diagnosis in Cutaneous Fistulas with Cyclic Secretion.

The development of a tubocutaneous fistula due to endometriosis in a post-cesarean section surgical scar is a rare complication that generates significant morbidity in the affected women. Surgery is the treatment of choice in these cases. Hormonal therapies may lead to an improvement in symptoms, but do not eradicate such lesions. In this report, we present a 34-year-old patient with a cutaneous fistula in the left iliac fossa with cyclic secretion. Anamnesis, a physical examination, and supplementary tests led us to suggest endometriosis as the main diagnosis, which was confirmed after surgical intervention.

RESUMO O desenvolvimento de fístula tubocutânea secundária à endometriose em cicatriz cirúrgica após cesariana é uma complicação rara, que gera importante morbidade às mulheres acometidas. A cirurgia é o tratamento de escolha nesses casos. Terapias hormonais podem conduzir a uma melhora dos sintomas, mas, de forma alguma, levam à erradicação de tais lesões. No presente relato, temos uma paciente de 34 anos de idade que apresentava uma fístula cutânea em fossa ilíaca esquerda com secreção cíclica. Anamnese, exame físico e exames complementares nos levaram a aventar como principal hipótese diagnóstica a endometriose, que foi confirmada após intervenção cirúrgica.

[Devastating surgical complications after aflibercept chemotherapy]. / Devastadora complicación tras tratamiento con aflibercept.

BACKGROUND: The use of a new chemotherapy as adjuvant treatment of colorectal cancer is not free of complications. Monoclonal antibodies are associated with bleeding and intestinal perforations. OBJECTIVE: To report the case of a patient who developed a serious complication after treatment with an antiangiogenic drug for colorectal neoplasm. CLINICAL CASE: The case is presented of a 42-year-old male operated on due to subocclusive rectal cancer with metástasis at the time of diagnosis. Sixteen months after surgery during second-line adjuvant therapy, an intestinal perforation was observed with haemorrhage and intestinal leak to retroperitoneum and left lower extremity. Despite intensive medical and surgical treatment this complication had fatal consequences. CONCLUSIONS: Future research should be directed at obtaining biomarkers for the specific use of antiangiogenic agents in order to decrease the rate of adverse factors.

Traqueostoma persistente: cierre con colgajo invertido. reporte de tres casos clínicos y revisión de la literatura / Persistent tracheostoma: closure with inverted flap. report of three cases and literature review

El traqueostoma persistente es la complicación tardía más frecuente asociada al uso de traqueostomía. Se reportan tres casos de pacientes que se les realizó un cierre exitoso del traqueostoma persistente mediante técnica de cierre primario por planos con colgajo invertido. Las ventajas del método utilizado son que representa una alternativa simple, susceptible de realizar con anestesia local y de manera ambulatoria, con excelentes resultados estéticos, mejorando significativamente la calidad de vida de estos pacientes.

Persistent tracheostoma is the most common late complication associated with the use of tracheostomy. We report three cases in which patients underwent a successful closure of persistent tracheostoma using primary closure in layers with inverted flap technique. The advantages of this method are that it represents a simple alternative and is able to be performed under local anesthesia on an outpatient basis, with excellent aesthetic results, significantly improving the quality of life of these patients.
