ABSTRACT

La strangulation de la verge chez l'enfant constitue une urgence urologique rare et nécessite une prise en charge précoce. Elle peut être à la base des plusieurs complications graves, notamment la fistule urétro-cutanée, la nécrose et l'amputation du pénis. Elles surviennent le plus souvent au cours des jeux, mais peut faire suite à une maltraitance de l'enfant. L'une des causes de maltraitance d'enfant en Afrique est l'énurésie primaire. Nous rapportons le cas d'un garçon de 9 ans qui nous a été amené pour déformation de la verge et difficulté à uriner suite à une auto- strangulation de la verge dans un contexte psychosocial particulier en rapport avec une énurésie.

Penile strangulation in children is a rare urological emergency and requires early management. It can be the basis of several serious complications, including urethrocutaneous fistula, necrosis and amputation of the penis. They most often occur during play, but can follow child abuse. One of the causes of child abuse in Africa is primary enuresis. We report the case of a 9-year-old boy who was brought to us for penile deformation and difficulty urinating following self-strangulation of the penis in a particular psychosocial context related to enuresis.

ABSTRACT

Objective:To investigate the management of granulation tissue during surgery for infected congenital preauricular fistula and to assess the surgical outcomes. Methods:To summarize the surgical methods and the treatment of granulation methods in 140 cases of congenital preauricular fistula during the period of infection treated in our department from January 2018 to September 2022. The study divided patients into an observation group （79 patients） undergoing fistulectomy without granulation treatment, and a control group （61 patients） where fistulectomy and granulation resection were performed concurrently.. After six months of follow-up, the wound healing, recurrence rates, and the aesthetic assessment of granulation healing were evaluated using the Stony Brook Scar Evaluation Scale（SBSES）. Results:The two surgical approaches were applied to a total of 140 patients with infected congenital preauricular fistula. There was no statistical difference in wound healing and recurrence rates between the observation group and the control group. However, the observation group exhibited smaller scars. Conclusion:In cases of infected congenital preauricular fistula, surgical removal without excising granulation tissue is feasible, leading to effective healing and lesser scar formation.

ABSTRACT

Introducción. El análisis de las técnicas y tipos de materiales a utilizar durante una reparación selar es fundamental para lograr una tasa de morbimortalidad aceptable. Objetivo. Realizar un análisis de los principales factores involucrados en la producción de una fístula de líquido cefalorraquídeo (LCR) durante la resección de un adenoma hipofisario y describir una serie de pautas a considerar en la selección del material más adecuado para la reparación selar. Materiales y Métodos. Se realizó una revisión retrospectiva de pacientes operados de adenoma de hipófisis por vía endonasal endoscópica, durante un período de 2 años, en la División Neurocirugía del Hospital de Clínicas "José de San Martín", de la Universidad de Buenos Aires, Ciudad Autónoma de Buenos Aires, Argentina. Se registraron los materiales utilizados con su respectiva técnica reconstructiva y las complicaciones observadas. Los resultados obtenidos fueron comparados mediante una revisión bibliográfica. Resultados. Entre los 19 casos operados, un 67 % correspondió a macroadenomas y un 37 % a microadenomas. En todos los casos, se realizó una reconstrucción multicapa, utilizando materiales sintéticos y autólogos. Se registraron complicaciones en 2 casos, donde el cierre fue con técnica bicapa. Consistieron en fístula de LCR y, en uno de ellos, se generó adicionalmente neumoencéfalo. Ambos casos fueron resueltos por vía quirúrgica mediante una técnica reconstructiva multicapa. Conclusiones. El factor decisivo más importante para prevenir una fístula de LCR es la utilización de una técnica multicapa, independientemente de los materiales utilizados. Existe una tendencia a una mayor utilización de materiales sintéticos, pretendiendo evitar incisiones adicionales y teniendo en cuenta que se presentan con una biocompatibilidad similar a la de los materiales autólogos(AU)

Background. Endoscopic approaches to the cranial base have presented several limitations during the selar reparation. An analysis of techniques and materials that are used is essential to get an acceptable morbidity and mortality rate. Objectives. To carry out an analysis of the main factors which are present in the production of cerebrospinal fluid leak during the resection of pituitary adenomas and to set parameters we consider are important in the decision of which materials are appropriate to use for selar reparation. Methods. The authors did a quantitative retrospective review of patients operated of pituitary adenomas, considering micro and macroadenomas, removed by endoscopic endonasal approach, for 2 years, in the Neurosurgery Division, Hospital de Clínicas "José de San Martín", Buenos Aires University, Buenos Aires City, Argentina. The materials were registered during their use with the respective intrasurgical reconstructive technique and the complications that appeared. Through a bibliographic review we compared our results with other centers. Results. Of 19 cases that were operated, 67% were macroadenomas (more than 1 cm) and 37% were microadenomas (less than 1 centimeter). In all the cases, we did a multilayer reconstruction, using synthetic and autologist materials. Between these patients, we registered 2 complications that were operated at first time by the bilayer technique. Both patients presented cerebrospinal leak in the postoperative stage. One of those presented additionally pneumoencephalus. Both patients were treated with surgery using a multilayer technique, considering which materials are better to seal and which are better to be containers. Conclusion. The most important factor to prevent a cerebrospinal fluid leak is the use of the correct multilayer technique, regardless the material that are used, synthetic or autologic, considering which are better as sealants and which as containers(AU)

Cerebral arteriovenous fistula should be considered as a cause of spontaneous subdural hematoma(AU)

ABSTRACT

La fístula esofagobronquial como complicación de infección fúngica invasiva se encuentra poco reportada; es más frecuente como complicación de ventilación mecánica prolongada o bien por neoplasias que afectan el tracto respiratorio y esófago gástrico. Los signos y síntomas de esta suelen ser inespecíficos y pueden solaparse con otras patologías. Los estudios por imágenes que ayudan al diagnóstico son el esofagograma y la tomografía axial computada con contraste oral. El tratamiento de esta va a depender de la causa subyacente y la localización de la fístula. A continuación, describimos el caso de un paciente con fístula broncoesofágica por infección fúngica debido a período prolongado de neutropenia y tratamiento quimioterápico.

ABSTRACT

Introducción: La fístula de Líquido Cefalorraquídeo (LCR) es una complicación frecuente de las cirugías de fosa posterior. Objetivo: Realizar una revisión bibliográfica de la prevención de la fístula mediante diferentes técnicas de reparación del defecto dural y analizar factores de riesgo en el manejo de la fistula postoperatoria. Materiales y Métodos: Realizamos una búsqueda bibliográfica de las bases de datos de Medline, Cochrane y Embase. Resultados: Se hallaron 413 estudios inicialmente, 367 fueron descartados y 46 fueron seleccionados. Conclusión: Concluimos que no existen selladores durales superiores a otros. Recomendamos el uso de autoinjertos por su facilidad, bajo costo y mayor efectividad, particularmente el pericráneo, combinado con parches durales como Duragen® o Selladores durales como DuraSeal®. En abordajes suboccipitales otra opción es fascia cervical. Sí no es posible obtener un autoinjerto, los parches durales de colágeno presentan mayor eficacia en combinación con Selladores de Polietilenglicol. En caso de producida la fístula, para el manejo terapéutico es necesario el uso de medidas conservadoras más Drenaje Lumbar Externo (DLE) de forma temprana ya que aumenta su eficacia(AU)

Background: Cerebrospinal fluid (CSF) leakage is a frequent complication of posterior fossa surgery. Objectives: To study a bibliographic review of fistula prevention through different dural defect repair techniques and analyze risk factors in the management of postoperative fistula. Methods: A bibliographic search was performed using Medline, Cochrane and Embase. Results: 413 studies were considered at the beginning, 367 were discarded and 46 were selected. Conclusion: To conclude that there is not an ideal dural sealant. We recommend the use of autografts due to their relative ease, low cost and high effectivity, particularly pericranium, combined with dural sealants like Duragen® or DuraSeal®. In the suboccipital approach cervical fascia is another option. If not technically possible the use of an autologous graft, collagen matrix have higher efficiency combined with Polietilenglicol Sealants. If CSF leakage appears, for the management is necessary the use of conservative actions associated with External Lumbar Drainage (ELD) as quickly as possible because it increases efficacy(AU)

ABSTRACT

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).

ABSTRACT

Objective: To investigate the efficacy and safety of pedunculated rectus abdominis combined with bilateral ureteral extravestheter drainage in the treatment of refractory bladder-vaginal stump fistula. Methods: The clinical data of 8 cases of the refractory bladder-vaginal stump fistula were admitted to the Second Hospital of Hebei Medical University and Henan Cancer Hospital and underwent the clinical treatment of bladder-vaginal stump from December 2019 to December 2022 were collected. The reason of refractory bladder-vaginal stump fistula was analyzed, the operation manner of pedunculated rectus abdominis combined with peduncle and bilateral ureter for the treatment of bladder-vaginal stump through extrabladder drainage was explored. The operation time, bleeding volume and clinical effect were record. Results: The median operation time of 8 patients was 150 minutes(120~180 min), and the median blood loss was 400 ml(200~600 ml). During the perioperative period, there were 2 cases of incision infection, delayed healing by debridement and dressing, 2 cases of incision rupture and suture wound healing after reoperation, and 2 cases of urinary tract infection were cured by anti-infection. When followed up for 6 months, 8 cases of vesicovaginal stump fistula were cured. Conclusion: Bilateral ureteral external drainage of the rectus abdominis muscle, has a practical effect in the treatment of refractory bladder-vaginal stump fistula, which can be one of the clinical repairing treatment.

ABSTRACT

Hip firearm injuries are rare injuries that could lead to serious complications, such as posttraumatic hip arthritis and coloarticular fistula. We report a case of a 25-year-old male who sustained a pelvic injury caused by a single bullet which led to a bilateral acetabular fracture, concomitant with a colon injury treated on an emergency basis by a diverting colostomy; acetabular fractures were treated conservatively by traction. After the patient recovered from the abdominal injury, he was presented with bilateral hip pain and limited motion; plain radiographs showed bilateral hip arthritis with proximal migration of the femoral head and bilateral acetabular defect classified as Paprosky type ⅢA. Reconstruction of the hips was performed using the same technique: impaction bone grafting for acetabular defect reconstruction and a reversed hybrid total hip arthroplasty (THA) 6 months apart. The patient presented with loosening of the left THA acetabular cup 3 years later, which was revised; then he presented with a discharging sinus from the left THA with suspicion of coloarticular fistula, which was confirmed using CT with contrast material. A temporary colostomy and fistula excision were performed, and a cement spacer was applied to the hip. After clearing the infection, a final revision THA for the left hip was performed. Treating post-firearm hip arthritis by THA is challenging, especially in the situation of neglected cases with the presence of an acetabular defect. Concomitant intestinal injury increases the risk of infection with the possibility of coloarticular fistula formation, which could present later. Working with a multidisciplinary team is paramount.

ABSTRACT

Objective:To explore the clinical value of recurrent laryngeal nerve dissection in the surgical treatment for congenital pyriform sinus fistula（CPSF）. Methods:The clinical data of 42 patients with CPSF were retrospectively analyzed. All patients were diagnosed and treated in the First Affiliated Hospital of Guangdong Pharmaceutical University. Results:During the operation, all patients' recurrent laryngeal nerves were dissected successfully, and fistulas were resected completely,no patients had complication of recurrent laryngeal nerve's damage.There were no recurrence cases during the 13 to 48 months of follow-up. Conclusion:The trend of congenital pyriform sinus fistula is closely related to recurrent laryngeal nerve, it's important to dissect the recurrent laryngeal nerve during the operation for congenital pyriform sinus fistula.

ABSTRACT

Objective:To compare the clinical effect of surgical treatment of congenital preauricular fistulas in children during the local infection period and static inflammatory period. Methods:Forty children with congenital preauricular fistula infection treated in our hospital from January 2020 to December 2022 were selected as the experimental group, and 39 children with congenital preauricular fistula inflammation at static period were selected as the control group. The fistula of the two groups of children aged between 1-14 years old was located in front of the foot of the ear wheel or the foot of the ear wheel, and all were unilateral fistulas. The postoperative follow-up was 6 months to 2 years, and the efficacy of the two groups was compared. Results:There was no significant difference in the healing rate of stage Ⅰ and stage Ⅱ between the two groups（P>0.05）. There was no significant difference in fistula recurrence rate and satisfaction with the preauricular scar between the two groups after treatment（P>0.05）. There was no significant difference in postoperative hospital stay between the experimental group and the control group（P>0.05）. Conclusion:The effect of surgical treatment of congenital preauricular fistula in the infected period is similar to that of surgical treatment in the static period of inflammation, and it can reduce the pain of dressing change under local anesthesia in children, avoid the second operation in children, and reduce the economic cost. This treatment method is worthy of clinical promotion. Appropriate incision and resection method were designed according to the fistula and infection sites.

ABSTRACT

El neumoencéfalo es una patología que comúnmente se presenta después de cirugía neuroquirúrgica y ocasionalmente endonasal. Estos se suelen manejar de manera conservadora, sin embargo, se pueden asociar a distintas etiologías las cuales los hacen recurrir. En este reporte presentamos dos casos de neumoencéfalo tardío post quirúrgico asociado a fístulas de LCR de bajo flujo, donde se discute su clínica, etiología y manejo posterior.

Pneumocephalus is a pathology that commonly occurs after endonasal surgery, these are usually managed conservatively, however they can be associated with different etiologies which make them recur. In this report we present two cases of post-surgical late pneumocephalus associated with low-flow CSF fistulae, where its symptoms, etiology, and subsequent management are discussed.

ABSTRACT

RESUMEN Antecedentes: el trauma maxilofacial corresponde a toda lesión traumática del macizo facial. Actualmente representa uno de los problemas de salud más importantes en el mundo. Nuestro objetivo es realizar un análisis de nuestra experiencia en las intervenciones realizadas en pacientes internados y sus complicaciones. Material y métodos: se realizó un estudio descriptivo, retrospectivo y observacional de 205 pacientes con fracturas maxilofaciales desde el año 2011 hasta el año 2019. Resultados: el 81,46% fueron hombres (n: 167) y el rango etario más afectado osciló entre los 21 y 30 años con el 38,54% (n:79). El accidente de tránsito 56,1% (n:115) fue el mecanismo de trauma más frecuente. Los tipos de fracturas faciales fueron: panfaciales 12,2% (n: 25), tercio superior 1,46% (n:3), tercio medio 72,2% (n:148) y tercio inferior 14,15% (n:29). Dentro del tercio superior, el 66,67% (n:2) fueron fracturas del seno frontal asociadas al hueso frontal, en el tercio medio las combinadas en un 54,73% (n:81) y en el tercio inferior, las complejas en el 34,48% (n:10). Fueron intervenidos 199 pacientes (97,07%). Solo el 11,56% (n:23) presentó alguna complicación. No se observaron complicaciones graves. Discusión: según nuestra serie, la mayoría de los pacientes fueron hombres jóvenes; la causa más frecuente, el accidente de tránsito, y el tercio medio, el más afectado, resultados estos similares a los de otros estudios publicados. El tratamiento quirúrgico fue principalmente reducción abierta y fijación con material de osteosíntesis de titanio, un procedimiento seguro y fiable, que permite restablecer la funcionalidad previa al traumatismo, con un índice muy bajo de complicaciones posoperatorias.

ABSTRACT Background: Maxillofacial trauma corresponds to all traumatic injuries affecting the facial bones. Nowadays, it represents one of the main healthcare issues worldwide. The aim of this study is to analyze our experience in the interventions performed in hospitalized and their complications. Material and methods: We performed a retrospective and observational study of 205 patients with maxillofacial fractures from 2011 to 2019. Results: 81.46% were men (n = 167) and 38.54% (n = 79) of the patients were between 21 and 30 years of age. Traffic collision was the most common mechanism of trauma (56,1%, n = 115). The types of facial fractures were panfacial (12.2%; n = 25), of the upper-third (1.43%; n = 3), of the middle-third (72.2%; n = 148) and of the lower third (14.15%; n = 29). In the upper third of the face frontal sinus fractures associated with the frontal bone were the most common (66.67%; n =2); in the middle-third combined fractures were most prevalent (54.73%; n = 81) while complex fractures were most frequent in the lower third (34,48%; n = 10). One-hundred and ninety-one patients were operated on (97.07%). Complications occurred in only 11.56% (n = 23) and were not serious. Discusion: In our series, most patients were young men, traffic collisions were the most common cause of trauma, and the middle third of the face was the most affected region. These results are similar to our publications. Surgical management, mostly by open reduction and fixation with titanium-based osteosynthesis material, is an effective, safe and reliable procedure, which allows the restoration of pre-trauma function, with very low rate of postoperative complications.

ABSTRACT

Abstract Endoluminal vacuum therapy (EVAC) is a promising alternative for the endoscopic management of gastrointestinal fistulas or perforations that do not respond to endoscopic procedures using clips and stents or are even refractory to surgical procedures. In this case report, we describe the successful endoscopic closure of an esophagogastric anastomotic fistula using EVAC, connected to a vacuum system through a probe in the cavity, which did not close with clip management given the friability and edema of the peri-wound tissue. In conclusion, it is a successful alternative to treat these complications, which are sometimes difficult to resolve.

Resumen La terapia de vacío endoluminal (Endo-Vac) es una alternativa promisoria en el manejo endoscópico de las fístulas o perforaciones gastrointestinales, que no responden a procedimientos endoscópicos cuando se utilizan técnicas como clips, stents o incluso refractarias a procedimientos quirúrgicos. En este reporte de caso describimos el cierre endoscópico exitoso de una fístula anastomótica esofagogástrica, utilizando la terapia Endo-Vac, conectada a un sistema de vacío mediante una sonda en la cavidad, que no presentó cierre inicial a manejo con clips, dada la friabilidad y el edema del tejido perilesional. Se concluye que esta es una alternativa exitosa en el cierre de estas complicaciones, que en ocasiones son de difícil resolución.

ABSTRACT

Introducción: La fístula traqueocutánea es la complicación más frecuente de la traqueostomía, que lleva a la necesidad de usar diferentes tipos de plastias para lograr un cierre definitivo. Objetivo: Mostrar una opción de tratamiento quirúrgico para garantizar un cierre definitivo de la fístula traqueocutánea recidivante. Caso clínico: Se presenta paciente masculino de 45 años con antecedentes de traqueostomía sin cierre espontáneo; quien desarrolló fístula traqueocutánea tratada con doble plastia de deslizamiento frontal tipo Szymanowski, con posterior recidiva, motivo por el que acude a consulta. Se realizó cierre directo de mucosa traqueal con plicatura de músculo platisma y avance de colgajos de piel rectangulares para reforzar cobertura de la pared anterior de la tráquea. Se logró corregir la fístula mediante un procedimiento simple, rápido y efectivo. Conclusiones: Este método evita las dificultades encontradas en otros procedimientos y garantiza la corrección funcional y estética con el empleo de una técnica simple con baja morbilidad(AU)

Introduction: Tracheocutaneous fistula is the most frequent complication of tracheostomy, leading to the need to use different types of plasties to achieve a definitive closure. Objective: To show a surgical treatment option for guaranteeing a definitive closure of recurrent tracheocutaneous fistula. Clinical case: We present the case of a 45-year-old male patient with a history of tracheostomy without spontaneous closure, who developed tracheocutaneous fistula managed through double plasty of anterior sliding of Szymanowski type, followed by recurrence. Direct closure of the tracheal mucosa was performed with platysma muscle plication and advancement of rectangular skin flaps for reinforcing coverage of the anterior wall of the trachea. Correction of the fistula was achieved by a simple, fast and effective procedure. Conclusions: This method avoids the difficulties found in other procedures, and guarantees functional and aesthetic correction with the use of a simple technique with low morbidity(AU)
