Double dartos flap layer in tubularized incised plate urethroplasty to prevent urethrocutaneous fistula in uncircumcised patients with distal hypospadias / 亚洲男科学杂志(英文版)

Urethrocutaneous fistula may complicate hypospadias repair. We noticed that double-layered preputial dartos flaps added to tubularized incised plate urethroplasty can reduce the risk of urethrocutaneous fistula. The aim of this study was to compare the outcomes of tubularized incised plate urethroplasty with double-layered preputial dartos flaps to with single-layered local fascial flaps in preventing urethrocutaneous fistula. A retrospective cohort study was conducted between January 2017 and December 2020 at Jordan University Hospital (Amman, Jordan). Boys who were aged between 6 months and 5 years, diagnosed with distal hypospadias, and not circumcised were included. The primary outcome was the occurrence of urethrocutaneous fistula in patients who underwent tubularized incised plate urethroplasty with a double-layered fascial flap. The results showed a total of 163 boys with distal hypospadias; among them, 116 patients underwent tubularized incised plate urethroplasty with a single-layered fascial flap, and 47 underwent tubularized incised plate urethroplasty with a double-layered fascial flap. The development of urethrocutaneous fistula was higher in the group receiving tubularized incised plate urethroplasty with a single-layered fascial flap than in the group receiving tubularized incised plate urethroplasty with a double-layered fascial flap after 1 month, 6 months, and 12 months (6.9% vs 0, 10.3% vs 0, and 5.2% vs 0, respectively), and the difference after 6 months was statistically significant (P = 0.02).

"Massive hemoptysis" and shock after fever and cough / 中国当代儿科杂志

A boy, aged 11 years, was admitted due to intermittent fever for 15 days, cough for 10 days, and "hemoptysis" for 7 days. The boy had fever and cough with left neck pain 15 days ago, and antibiotic treatment was effective. During the course of disease, the boy developed massive "hemoptysis" which caused shock. Fiberoptic bronchoscopy revealed a left pyriform sinus fistula with continuous bleeding. In combination with neck and vascular imaging examination results, the boy was diagnosed with internal jugular vein injury and thrombosis due to congenital pyriform sinus fistula infection and neck abscess. The boy was improved after treatment with temperature-controlled radiofrequency ablation for the closure of pyriform sinus fistula, and no recurrence was observed during the follow-up for one year and six months. No reports of massive hemorrhage and shock due to pyriform sinus fistula infection were found in the searched literature, and this article summarizes the clinical features, diagnosis, and treatment of this boy, so as to provide a reference for the early diagnosis of such disease and the prevention and treatment of its complications.

Las anomalías de las hendiduras y arcos branquiales son la segunda causa más común de lesiones congénitas de cabeza y cuello en niños. Representan el 8% de todas las malformaciones congénitas y el 30% de las de cabeza y cuello. Pueden permanecer asintomáticas o manifestarse como una tumefacción y asociarse a infecciones recurrentes supuradas en la región preauricular, subauricular o retroauricular, en las regiones de la parótida y/o del cuello. Fueron reportados casos asociados a malformaciones óticas.La tomografía computada de alta resolución y la resonancia magnética con gadolinio pueden ayudar al diagnóstico. El tratamiento médico antibiótico está indicado ante una infección aguda, además de incisión y drenaje en los procesos abscedados. El tratamiento definitivo es quirúrgico con la extirpación completa de la lesión. Se presenta a un niño de 6 años de edad con infección aguda en la región retroauricular derecha en el oído disgenésico

Branchial cleft anomalies are the second most common congenital head and neck lesions in children. The first congenital head and neck lesion is thyroglossal duct cysts. First branchial cleft anomalies are rare congenital head and neck malformations (8% of branchial cleft anomalies).The initial clinical manifestation was recurrent infections and/or discharge in auricular, periauricular, parotid or upper neck regions. These anomalies are extremely rare and other associated facial malformations were described.The computed tomography and magnetic resonance can help the diagnosis. The antibiotic treatment is indicated in acute infection. Also, incision and drainage are recommended in abscessed processes.In this report, we present a case of retroauricular sinus infection in a 6-year-old child with congenital ear anomalies

Mini-incision with endoscope-assisted surgery for bilateral congenital second branchial cleft fistula and a pedigree report / 中华耳鼻咽喉头颈外科杂志

Objective: To investigate the feasibility and efficacy of mini-incision with endoscope-assisted resection for bilateral congenital second branchial cleft fistula, and to report on a rare pedigree. Methods: The clinical data of 5 patients with bilateral congenital second branchial fistula admitted in Fujian Provincial Hospital from April 2007 to December 2018 were retrospectively reviewed, including 2 males and 3 females, aged from 3 to 31 years old. The surgical strateges and clinical experience of single mini-incision with endoscope-assisted fistulectomy were summarized, and a rare pedigree was reported. Results: In five patients, Case 1 to Case 4 were treated with bilateral endoscopic-assisted fistula high ligation with titanium clips and removal through a single small incision under general anesthesia. No obvious complications occurred after the operation. The patients were followed up for 40-164 months with no fistula recurrence. Case 5 gave up surgical resection and was followed up for 24 months with acute infection attack once. Case 2 and Case 4 came from the same family. In this family, 7 out of 31 members of four generations had second branchial cleft fistulas, of which 4 were bilateral and 3 were right. Pedigree analysis was consistent with autosomal dominant inheritance. No deafness, preauricular tag, external and middle ear deformity and kidney malformation were found in the family members. Conclusions: Bilateral congenital second branchial cleft fistula is rare. Surgical resection is the preferred treatment. Mini-incision with endoscopic-assisted fistula high ligation with titanium clip and resection has clear operative field, ideal cosmetic effect and definite curative effect.

A comparison between endoscopic CO2 laser cauterization and open neck surgery in the treatment of congenital piriform fistula / 中华耳鼻咽喉头颈外科杂志

Objective: To compare the efficacy, advantages and disadvantages of endoscopic CO2 laser cauterization (ECLC) and open neck surgery in the treatment of congenital pyriform sinus fistula (CPSF). Methods: From September 2014 to March 2017, 80 cases with confirmed diagnosis of CPSF received initial treatment at Guangdong Provincial People's Hospital were prospectively analyzed, including 34 males and 46 females, aged 18 to 672 (194.17±141.18) months. They were consecutively divided into endoscopic group and open-surgery group, with 40 cases in each group. Both groups of patients received surgical treatment under general anesthesia. The endoscopic group was treated by endoscopic CO2 laser cauterization, and the open-surgery group underwent the following surgery: first, we performed suspension laryngoscopy examination to confirm the presence of fistula in the bottom of the piriform fossa, then open-neck resection of congenital piriform sinus fistula with recurrent laryngeal nerve and/or lateral branch of superior laryngeal nerve anatomy plus partial thyroidectomy were performed. The data between the two groups were compared, including the operative time, intraoperative blood loss, postoperative pain, average length of stay, neck cosmetic scores, complications and cure rates. All patients were followed up in outpatient clinics. Statistical analysis was performed using SPSS 20.0 software. P<0.05 indicates that the difference is statistically significant. Results: All patients were successfully completed the operation. The operative time, intraoperative blood loss, postoperative pain and average length of hospital stay in the endoscopic group were significantly less than those in the open group [(27.4±5.5) min to (105.8±52.5) min, (0.6±0.5) ml to (33.6±41.5) ml, (1.7±0.9) points to (4.6±0.7) points, (5.9±2.9)d to(8.9±3.3)d, t values were-9.400, -5.031, -16.199, -4.293, P values were all<0.01]; The neck cosmetic score in the endoscopy group was significantly greater than that of the open group [(9.9±0.4) against (5.8±0.9) points, t=25.847, P<0.01]. Compared with the open group (15.0%, 6/40), the complication rate of the endoscopic group (7.5%, 3/40) was not statistically significant (χ²=0.50, P>0.05). Three months after the first treatment, the cure rate in the endoscopic group (82.5%, 33/40) was significantly lower than that in the open-neck group (100.0%, 40/40), χ²=5.64, P<0.05. The follow-up time was 12 months after the last treatment. Eighty cases were followed up and none was lost to follow-up. During the follow-up period, the cure rate of the endoscopy group (97.5%, 39/40) was compared with that of the open group (100.0%, 40/40), and the difference was not statistically significant. Conclusions: In the treatment of CPSF, the two-surgical method each has their advantages. Compared with open-neck surgery, ECLC is simpler, repeatable. ECLC has shorter time in operation and hospital stay, less complications, and less postoperative pain and more precise cosmetic results. It could be preferred for the initial treatment of CPSF and relapsed cases after cauterization. But subject to relatively low cure rate of one-time cauterization and uncertain long-term efficacy, it cannot completely replace the open-neck surgery at present.

Introducción: La fístula arterio-venosa para hemodiálisis es el acceso vascular utilizado con mayor frecuencia. De su adecuada funcionalidad depende la calidad de vida de los pacientes con enfermedad renal crónica. Objetivo: Caracterizar a los pacientes a los que se les confeccionó fístulas arterio-venosas para hemodiálisis. Métodos: Se realizó un estudio descriptivo retrospectivo en 73 pacientes, a los que se les confeccionó una fístula arterio-venosa para hemodiálisis. Las variables de estudio fueron: edad, sexo, tipo de fístula arterio-venosa, localización, complicaciones y tratamiento quirúrgico de las complicaciones. Resultados: Se encontró un predominio del sexo masculino y del grupo etario entre 51 y 60 años. El 94,6 por ciento de las fístulas realizadas fueron autólogas; y, de estas, el 44,1 por ciento, radio-cefálicas. El 27,3 por ciento de las autólogas y el 20 por ciento de las protésicas se presentó trombosis, y el 18,2 por ciento y el 40 por ciento presentaron hipertensión venosa para las autólogas y protésicas, respectivamente. El 43,5 por ciento de los tratamientos realizados frente a las complicaciones resultó la confección de una nueva fístula. Conclusiones: Los pacientes a los que se les confeccionó fístulas arterio-venosas eran predominantemente adultos mayores del sexo masculino y las fístulas más realizadas fueron las autólogas radio-cefálicas. Como principal complicación de las fístulas se encontró la trombosis y se realizaron escasos procederes para el rescate de estas(AU)

Introduction: Arterio-venous fistula for haemodialysis is the most commonly used vascular access. Its proper functionality depends on the quality of life of patients with chronic kidney disease. Objective: Describe patients to whom were made arterio-venous fistulas for haemodialysis. Methods: A retrospective descriptive study was conducted in 73 patients to whom were made an arterio-venous fistula for haemodialysis. The study variables were: age, sex, type of arterio-venous fistula, location, complications and surgical treatment of complications. Results: It was found a predominance of male sex and the age group of 51 to 60 years. 94.6 percent of the fistulas made were autologous; and, of these, 44.1 percent were radio-cephalic. 27.3 percent of the autologous fistulas and 20 percent of the prosthetics ones developed thrombosis, and 18.2 percent and 40 percent showed venous hypertension for autologous and prosthetic fistulas, respectively. 43.5 percent of the treatments performed to face complications resulted in the making of a new fistula. Conclusions: The patients to whom were made arterio-venous fistulas were predominantly older adults of the male sex and the most performed fistulas were the radio-cephalic autologous. As the main complication of fistulas, thrombosis was found and a few practices were performed to rescue them(AU)

Fístula aorto-ileal primaria / Primary Aortoenteric Fistulas

RESUMEN Introducción: Las fístulas aorto-entéricas son una causa infrecuente de hemorragia digestiva. El pronóstico, generalmente ominoso, depende de una alta sospecha clínica y diagnóstico oportuno. Objetivo: Presentar el caso de una hemorragia digestiva por una fístula Aortoentérica diagnosticada y tratada. Presentación del caso: Se reporta el caso de un hombre de 72 años intervenido con el diagnóstico hemorragia digestiva masiva en el preoperatorio; sin embargo, el diagnóstico de la fístula se hizo en el intraoperatorio, sin observar dilatación aneurismática, pero si una aorta ateromatosa y un proceso inflamatorio hacia la fístula. Se realizó reparación quirúrgica urgente con reparación cara anterior aorta infrarrenal cercana a la bifurcación y resección del íleo terminal con ileoascendentostomía termino-lateral. Discusión: Las fístulas aorto-entéricas es una causa potencialmente fatal de hemorragia digestiva. El diagnóstico continúa siendo un desafío debido a su presentación inespecífica y siempre debiese ser considerado frente a una hemorragia digestiva sin causa aparente. Existen varias opciones para el enfrentamiento quirúrgico que deben ser analizadas caso a caso, sin retrasar la reparación. Conclusiones: La fístula aorto-entérica primaria es una causa poco frecuente de hemorragia digestiva, que todo médico y cirujano debe tener en cuenta frente a un paciente con sangrado digestivo de causa no precisada(AU)

ABSTRACT Introduction: Aortoenteric fistulas are a rare cause of gastrointestinal bleeding. The generally ominous prognosis depends on high clinical suspicion and timely diagnosis. Objective: To present a case of gastrointestinal hemorrhage for aortoenteric fistula diagnosed and treated. Case presentation: The case is reported of a 72-year-old man who received surgery after the diagnosis of massive gastrointestinal bleeding during the preoperative period. However, the diagnosis of the fistula was made intraoperatively, without observing aneurysmal dilation, but an atheromatous aorta and an inflammatory process leading to the fistula instead. Urgent surgical repair was performed with repair of anterior infrarenal aorta near the bifurcation and resection of the terminal ileum with end-to-side ascending ileostomy. Discussion: Aortoenteric fistulas are a potentially fatal cause for gastrointestinal bleeding. Diagnosis continues to be a challenge due to its nonspecific presentation and should always be considered for any case of unexplained gastrointestinal bleeding. There are several options for surgical management that must be analyzed case by case, without delaying repair. Conclusions: Primary aortoenteric fistula is a rare cause for gastrointestinal bleeding, which every doctor and surgeon must take into account when dealing with a patient with digestive bleeding of an unspecified cause(AU)

Factores de riesgo en la aparición de fístula faringocutánea / Risk factors in the apparition of pharyngocutaneous fistula

RESUMEN Introducción: la fístula faringocutánea es la complicación postoperatoria más frecuente de la laringectomía total. Incrementa la morbimortalidad, demora la administración del tratamiento oncológico y repercute en la esfera psicológica del paciente. Objetivo: conocer el comportamiento de la fístula faringocutánea en pacientes con laringectomía total. Materiales y métodos: se realizó un estudio observacional, descriptivo, retrosprospectivo en el Hospital Universitario "Comandante Faustino Pérez", en el período comprendido entre enero 2010 a diciembre 2015. El universo lo constituyó 143 pacientes laringectomizados. Se estudiaron las variables: edad, sexo, estado nutricional previo a la cirugía, estadio del tumor, radiaciones, traqueostomía; manejo del cuello, previo a la cirugía, y evolución de la fístula. Resultados: presentó fístula postoperatoria el 28 %, predominando el sexo masculino, en un 92.3 %; y los normopesos en un 56,6 %. Se encontraban en estadio IV, el 70 %. Fueron irradiados 72,5 % y se les practicó traqueostomía, previa a la cirugía, al 95 % de los pacientes. Vaciamiento cervical se realizó al 37,5 %. En el 70 % de los pacientes, la fístula apareció entre los 8 y 14 días. Conclusiones: la incidencia de la fístula faringocutánea es mayor en el sexo masculino entre los 60-69 años. La mayor incidencia ocurrió en el año 2015. El estadio avanzado del tumor, la presencia de traqueostomía, el estado nutricional e irradiación previa, fueron los factores que más incidieron en la aparición de fístula faringocutánea. En la mayoría de los pacientes el cierre fue espontáneo con buena su evolución (AU).

ABSTRACT Introduction: pharyngocutaneous fistula is the most frequent post-surgery complication of the total laryngectomy. It increases morbimortality, delays the administration of the oncological treatment and rebounds in the patient's psychological sphere. Objective: to know the behavior of the pharyngocutaneous fistula in patients with total laryngectomy. Materials and methods: a retrospective, descriptive, observational study was carried out in the University Hospital "Comandante Faustino Pérez", in the period from January 2010 until December 2015. The universe were 143 patients who undergone a laryngectomy. The studied variables were age, sex, nutritional status before the surgery, tumor stage, radiations, tracheotomy, neck management before surgery, and fistula evolution. Results: 28 % of the patients presented post-surgery fistula, predominantly among males (92.3 %). Normal weight patients were 56.6 %; 70 % were in the IV stage. 72.5 % of the patients were irradiated and 95 % undergone tracheotomy before the surgery. 37.5 % of them undergone cervical resection. In 70 % of the patients, the fistula appeared after 8-14 days. Conclusions: the incidence of the pharyngocutaneous fistula is higher in the male sex and the 60-69 years age-group. The highest incidence occurred in 2015. The advanced stage of the tumor, the presence of tracheotomy, the nutritional status and previous irradiation were the factors that had more incidences on pharyngocutaneous fistulae. The closure of the fistula was spontaneous in most of the patients, with a good evolution (AU).

Vesicouterine fistula (Youssef syndrome): case report and literature review / Fístula vesico-uterina (síndrome de Youssef): descrição de caso e revisão da literatura

Abstract Objective To describe a case of vesicouterine fistula and to review the literature related to this condition. Methods For the review, we accessed the MEDLINE, BIREME and LILACS databases; the references of the searched articles were also reviewed. Results A 38-year-old woman, in the 1st day after her 3rd cesarean, presented heavy hematuria, which was considered secondary to a difficult dissection of the bladder. A total of 6 months after delivery, she failed to resume her regular menstrual cycles and presented cyclic menouria and amenorrhea. At this time, she had two episodes of urethral obstruction by blood clots. She remained without a correct diagnosis until about two years postdelivery, when a vesicouterine fistula was confirmed through cystoscopy. A surgical correction through open abdominal route, coupled with hysterectomy, was performed. After the surgery, the symptoms disappeared. The review showed a tendency of change in the relative frequency of the different types of genitourinary fistulae. Vesicovaginal fistulae, usually caused by inadequate care during labor, are becoming less frequent than those secondary tomedical procedures, such as vesicouterine fistulae. The most common cause of this latter kind of fistula is cesarean section, especially repeated cesarean sections. The diagnosis is confirmed through one or more imaging exams, or through cystoscopy. The most common treatment is surgical, and the routes are: open abdominal, laparoscopic, vaginal or robotic. There are some reports of success with the conservative treatment. Conclusion Vesicouterine fistulae are becoming more common because of the increase in the performance of cesarean sections, and the condition must be considered a possible complication thereof.

Resumo Objetivo Apresentar um caso de fístula vesico-uterina e realizar revisão da literatura sobre esta condição. Métodos Revisão realizada consultando-se as bases MEDLINE, BIREME e LILACS, além das referências dos artigos consultados. Resultados Uma mulher de 38 anos, após sua terceira cesárea, no puerpério imediato, apresentou hematúria importante, que foi atribuída a uma dificuldade na dissecção da bexiga durante o procedimento. Seis meses pós-parto, emvez de retomar os ciclos menstruais regulares, apresentou menúria cíclica e amenorreia (síndrome de Youssef). A paciente chegou a apresentar obstrução uretral por coágulos, e permaneceu sem diagnóstico correto até cerca de anos pós-parto, quando este foi feito por cistoscopia. Ela foi então submetida a correção cirúrgica por via abdominal, associada a uma histerectomia, com desaparecimento dos sintomas. A revisão mostrou que tem havido mudança na frequência dos vários tipos de fístulas urogenitais. As fístulas vesicovaginais, normalmente secundárias à má assistência durante o parto, têm sido mais raras, enquanto aquelas secundárias a procedimentos médicos, como as vesicouterinas, têm sido mais frequentes. A causa mais comum deste tipo de fístula é a cesárea, especialmente a de repetição. A apresentação pode ser de amenorreia e menúria e/ou perda urinária. O diagnóstico é feito por um ou maismétodos de imagem ou cistoscopia. O tratamento mais comum é cirúrgico, por via abdominal aberta, laparoscópica, transvaginal ou robótica. Existem relatos de cura com tratamento conservador. Conclusão As fístulas vesicouterinas têm sido mais comuns devido ao aumento da proporção de cesáreas. Deve-se ter em mente a possibilidade deste diagnóstico e considerá-las uma das possíveis complicações da cesárea.

Correção de fissura palatina com retalho músculo mucoso de bucinador: resultados de 6 casos após 27 anos / Correction of palatine fistulas with a musculo-mucosal buccinator flap: results of 6 cases after 27 years

Introdução: O retalho miomucoso de músculo bucinador, descrito em 1989, pode ser utilizado para corrigir fístulas palatinas, fissuras com alongamento do palato mole ou cobrir áreas cruentas após ressecções de tumores. Métodos: Trata-se da análise do resultado após 27 anos de 6 casos de pacientes operados no Hospital de Base e na Santa Casa de São José do Rio Preto, no período de 1984 a 1989, e reavaliados em 2016, nos quais foram realizados retalhos miomucosos de bucinador para correção de fissura palatina. Resultados: Dos 36 casos operados, 6 foram reavaliados após 27 anos, dos quais 5 trataram-se de correção primária e 1 de correção secundária (fístula após fechamento de fissura palatina). Todos os casos obtiveram resultados satisfatórios no crescimento maxilar, na correção da fistula palatina e na função da fala. Conclusão: Apesar de estatisticamente não significativo, o presente estudo demonstrou que o retalho miomucoso de músculo bucinador para correção e alongamento do palato é um procedimento adequado, com resultados de crescimento maxilar normal ou próximo disso e fala praticamente normal, mesmo sem adequado tratamento fonoaudiológico.

Introduction: The buccal musculo-mucosal patch, described in 1989, can be used to correct palatine fistulas and fissures with stretching of the soft palate, or to cover bloody areas after tumor resection. Methods: This is an analysis of the 27-year postoperative results for 6 patients who underwent operation at Base Hospital and Santa Casa de São José do Rio Preto between 1984 and 1989, and reassessed in 2016, when a myo-buccinator mucosa was used for cleft palate correction. Results: Of the 36 operated cases, 6 were reevaluated after 27 years, of which 5 had primary correction and 1 had a secondary correction (fistula after cleft palate closure). All the cases had satisfactory results in terms of maxillary growth, correction of the palatine fistula, and speech function. Conclusion: Although not statistically significant, the present study demonstrated that the buccal musculo-mucosal flap is an adequate procedure for correction and stretching of the palate, with normal or near-normal maxillary growth and practically normal speech even without adequate phono-audiological treatment.

Laparoscopic nephrectomy outside gerota fascia and en bloc ligation of the renal hilum for management of inflammatory renal diseases

ABSTRACT Objectives This study aims to improve laparoscopic nephrectomy techniques for inflammatory renal diseases (IRD) and to reduce complications. Materials and Methods Thirty-three patients underwent laparoscopic nephrectomy for IRD, with a method of outside Gerota fascia dissection and en-bloc ligation and division of the renal pedicle. Operative time, blood loss, complications, analgesia requirement, post-operative recovery of intestinal function and hospital stay were recorded. The degrees of perinephric adhesion were classified based on the observation during operation and post-operative dissection of the specimen, and the association of different types of adhesion with the difficulty of the procedures was examined. Results Among 33 cases, three were converted to hand-assisted laparoscopy, and one was converted to open surgery. Mean operative time was 99.6±29.2min, and blood loss was 75.2±83.5 mL. Postoperative recovery time of intestinal function was 1.6±0.7 days and average hospital stay was 4.8±1.4 days. By classification and comparison of the perinephric adhesions, whether inflammation extending beyond Gerota fascia or involving renal hilum was found to be not only an important factor influencing the operative time and blood loss, but also the main reason for conversion to hand-assisted laparoscopy or open surgery. Conclusions In laparoscopic nephrectomy, outside Gerota fascia dissection of the kidney and en-bloc ligation of the renal pedicle using EndoGIA could reduce the difficulty of procedure and operative time, with satisfactory safety and reliability. Inflammation and adhesion extending beyond Gerota fascia or involving renal hilum is an important predictor of the difficulty related to laparoscopic nephrectomy for IRD.

Fístulas del seno piriforme congénitas: reporte de 4 casos y revisión de la literatura / Congenital pyriform sinus fistula: report of 4 cases and review of the literature

Resumen Introducción: Las fístulas del seno piriforme, originadas desde el tercer o cuarto arco branquial, son entidades poco frecuentes. Se pueden presentar como aumento de volumen cervical, fístula cervical, absceso cervical, tiroiditis abscedada y/o disfonía. Objetivo: Reportar 4 casos tratados en nuestro hospital y revisión de la literatura. Discusión: Frente a un cuadro clínico compatible, se debe realizar estudio endos- cópico y de imágenes. El manejo quirúrgico sigue siendo el de mejores resultados, pero se han desarrollado terapias endoscópicas y combinaciones de estas con buenos resultados. Conclusión: El diagnóstico requiere un alto índice de sospecha clínica. La cirugía abierta se mantiene como el gold standard, sin embargo, en población pediátrica estaría indicada la resolución endoscópica debido a la alta morbilidad de la cirugía tradicional.

Introduction: Pyriform sinus fistula is a rare cervical branchial anomaly derived from the third and fourth branchial arch. Pyriform sinus fistula should be considered in children presenting enlarged neck mass, fistula, abscess, thyroid infection and/or dysphonia. Objective: We here report 4 cases treated in Hospital Clínico Universidad de Chile and review of the current literature on pyriform sinus fistula. Discussion: When clinical presentation is compatible with pyriform sinus fistula, endoscopic and imaging techniques are required. Surgical outcomes are better, although endoscopic therapies and combination of both surgery and endoscopy have also reported good outcomes. Conclusion: Diagnosis is made based on signs and symptoms and a high index of clinical suspicion. Open surgery is gold standard, however in pediatric population endoscopic resolution should be considered to reduce the high morbidity of traditional surgery.

Tratamiento de fistula palatina anterior mediante colgajo de lengua / Treatment of anterior palatal fistula through tongue flap

La fístula palatina anterior es la comunicación anormal entre la cavidad oral y la nariz que se presenta después del cierre quirúrgico de la fisura palatina, ésta ocurre con más frecuencia en defectos de paladar duro. El colgajo de lengua está indicado para la reconstrucción de grandes fístulas palatinas y con excesivas cicatrices palatinas luego de varios procedimientos insatisfactorios. El colgajo ofrece varias ventajas ya que presenta abundante tejido, excelente irrigación y es de fácil rotación. El resultado fue satisfactorio.

The anterior palatal fistula is the abnormal communication between the oral cavity and nose that occurs after surgical closure of cleft palate, this occurs more frequently in hard palate defects. Tongue flap is indicated for the reconstruction of large fistulas and excessive palatal scars after several unsatisfactory procedures. The flap offers several advantages since it presents abundant tissue, excellent irrigation and easy rotation. The result was satisfactory.

Ressonância de fala e complicações cirúrgicas após palatoplastia primária com veloplastia intravelar em pacientes com fissura de lábio e palato / Speech resonance and surgical complications after primary palatoplasty with intravelar veloplasty in patients with cleft lip and palate

INTRODUÇÃO: A correção cirúrgica primária do palato é de fundamental importância na reabilitação do indivíduo com fissura labiopalatina e visa tanto a restauração anatômica local, com o fechamento da comunicação existente entre a cavidade nasal e oral, como a restauração funcional do anel velofaríngeo por meio do reposicionamento dos músculos palatinos. Ao longo dos anos, as técnicas de fechamento de palato foram evoluindo progressivamente, utilizando, cada vez mais, o procedimento de reposicionamento da musculatura responsável pelo fechamento do esfíncter velofaríngeo, denominado veloplastia intravelar. Tal procedimento favorece o funcionamento sinérgico da musculatura velar e faríngea, evitando, assim, os sintomas decorrentes da insuficiência velofaríngea. No entanto, apesar de todos os esforços no sentido de conseguir o funcionamento velofaríngeo adequado, intercorrências intraoperatórias e complicações pós-operatórias imediatas e/ou tardias podem contribuir para o insucesso da palatoplastia primária e, consequentemente, levar ao aparecimento de hipernasalidade. MÉTODOS: Sessenta pacientes submetidos à palatoplastia primária com veloplastia intravelar. Intercorrências intraoperatórias e complicações pós-operatórias imediatas e tardias foram investigadas. A presença e localização de fístula ou deiscência do palato foi feita por meio de avaliação clínica. Os pacientes foram submetidos, também, à gravação em áudio de amostra de fala, as quais foram analisadas por três fonoaudiólogas. As intercorrências intraoperatórias e as complicações pós-operatórias foram analisadas de forma descritiva. A associação entre as intercorrências intraoperatórias e complicações imediatas e tardias com a formação de fístulas, bem como a associação entre a ocorrência de fístulas e deiscências com a presença e ausência de hipernasalidade, foram analisadas por meio de Teste de Fisher. RESULTADOS: Verificou-se 5% de intercorrências intraoperatórias, 20% de complicações imediatas e 13,3% de complicações tardias. O índice de fístulas foi de 16,67%. A proporção de hipernasalidade foi de 18,6%. CONCLUSÃO: A palatoplastia com veloplastia intravelar utilizada no presente estudo demonstrou ser uma técnica segura, de fácil execução, eficiente para a fala e com baixos índices de complicações.

INTRODUCTION: The primary surgical correction of the palate is of fundamental importance in the rehabilitation of individuals with labiopalatine cleft and aims for local anatomical restoration and closure of the existing communication between the nasal and oral cavities, such as functional restoration of the velopharyngeal ring through repositioning of the palatine muscles. Palate closure techniques have evolved progressively over the years and increasingly involve repositioning of the muscles responsible for closing the velopharyngeal sphincter, called intravelar veloplasty. This procedure encourages the synergistic operation of the velar and pharyngeal musculature, thereby avoiding the symptoms resulting from velopharyngeal insufficiency. However, despite efforts to achieve adequate velopharyngeal function, intraoperative events and immediate postoperative and/or late complications may contribute to primary palatoplasty failure and consequently lead to hypernasality. METHODS: Sixty patients underwent primary palatoplasty with intravelar veloplasty. Intraoperative events and immediate and late postoperative complications were investigated. The presence and location of palatal fistula or dehiscence was assessed by clinical evaluation. The patients also made an audio recording of their speech that was analyzed by three speech therapists. The intraoperative events and postoperative complications were descriptively analyzed. The association between intraoperative events and immediate and late postoperative complications with the formation of fistulae as well as that between the occurrence of fistulae and dehiscences and the presence and absence of hypernasality was analyzed using Fisher's exact test. RESULTS: Overall, there was a 5% incidence of intraoperative events, 20% incidence of immediate complications, and 13.3% incidence of late complications. Fistulae and hypernasality were found in 16.67% and 18.6% of cases, respectively. CONCLUSION: Palatoplasty with intravelar veloplasty is a safe and easily implemented technique that is efficient for speech and has low complication rates.
