Negative pressure device used in pediatric patients with Hostile abdomen. Case series. / Dispositivo de presión negativa empleado en pacientes pediátricos con abdomen hostil: serie de casos.

INTRODUCTION: Hostile abdomen is a surgical condition characterized by loss of space between organs and structures in the abdomen. Negative pressure therapy use has been widely described in adults; the case is not the same for pediatric patients. The goal of this study is to present short-term results of negative pressure therapy use in pediatric patients with hostile abdomen due to different etiologies. MATERIAL AND METHODS: Pediatric hostile abdomen patients (< 18 years) who were treated Negative pressure therapy using ABTHERA were identified and retrospectively reviewed. RESULTS: 7 patients were included in this study. Median age was 16 (range: 9-17 yo). 5 (71.4%) were male and 2 (28.6%) females. 3 (43%) had significant past medical/surgical history (Systemic Lupus Erythematosus, complicated appendectomy and ventriculoperitoneal-shunt). The device was set at a continuous pressure ranging from -50 to -125 mmHg. Pre and post-surgical findings were reported using Bjork's classification. Devices were replaced every 4-7 days (median 5 days). Total amount of replacements was 1-4 (median 3). 5 (71.4%) patients required invasive mechanical ventilation during use of Negative pressure therapy based on clinical status. 4 (57%) patients received enteral nutrition. 1 (14%) patient required re-intervention posterior to definitive closure due to retroperitoneal abscess development. Outcome, evaluated by (oral tolerance, bowel movement and absence of pain), was favorable in all patients. CONCLUSION: Negative pressure therapy devices generate favorable results in hostile abdomen in pediatric population but further information is needed to assess pressure settings and device replacement frequency.

INTRODUCCION: El abdomen hostil es una patología quirúrgica caracterizada por una pérdida de espacio entre los órganos y estructuras del abdomen. La terapia de presión negativa se ha descrito de manera extensa en adultos, pero no así en pacientes pediátricos. El objetivo de este estudio es presentar los resultados a corto plazo de la terapia de presión negativa en pacientes pediátricos con abdomen hostil debido a distintas etiologías. MATERIAL Y METODOS: Identificación y análisis retrospectivo de los pacientes pediátricos con abdomen hostil (< 18 años) tratados con terapia de presión negativa ABTHERA. RESULTADOS: Se incluyó a 7 pacientes. La mediana de edad fue de 16 años (rango: 9-17). 5 (71,4%) eran niños y 2 (28,6%) niñas. 3 (43%) presentaban antecedentes médico-quirúrgicos de interés (lupus eritematoso sistémico, apendicectomía complicada y derivación ventriculoperitoneal). El dispositivo se empleó a presión constante, entre ­50 y ­125 mmHg. Los hallazgos preoperatorios y postoperatorios se notificaron mediante la clasificación de Bjork. Los dispositivos se sustituyeron cada 4-7 días (mediana de 5 días). La cantidad total de reemplazos fue de 1-4 (mediana de 3). 5 (71,4%) pacientes precisaron ventilación mecánica invasiva durante la terapia de presión negativa debido al estado clínico. 4 (57%) pacientes recibieron nutrición enteral. 1 (14%) paciente requirió reintervención posterior al cierre definitivo por el desarrollo de un absceso retroperitoneal. El resultado, evaluado en base a la tolerancia oral, el movimiento intestinal y la ausencia de dolor, fue favorable en todos los pacientes. CONCLUSION: Los dispositivos de terapia de presión negativa aportan resultados favorables en los pacientes pediátricos con abdomen hostil, aunque se necesita más información para evaluar los ajustes de presión y la frecuencia de reemplazo del dispositivo.

Tratamiento de hernias inguinales en niñas con técnica lapa-roscópica de Burnia versus cirugía abierta / Treatment of inguinal hernias in girls with laparoscopic Burnia technique versus open surgery

Introducción: En la actualidad se amplía el debate sobre qué técnica sería mejor comparando la cirugía abierta con la técnica laparoscópica, y el interés cosmético a futuro en pacientes mujeres que requieren la resolución quirúrgica de una hernia inguinal, por lo que el objetivo del presente estudio fue hacer una descripción de niñas con hernia inguinal sometidas a técnicas de corrección laparoscópica (técnica de Burnia) versus cirugía convencional para hernias inguinales. Métodos: El presente estudio observacional fue realizado en el Hospital de Niños Dr. Roberto Gilbert Elizalde, de Guayaquil, Ecuador, de enero del 2021 al febrero del 2022. Con una muestra no probabilística ingresaron al estudio niñas sometidas a tratamiento quirúrgico por hernia inguinal. Se registró la edad, técnica quirúrgica, estancia hospitalaria, tiempo quirúrgico y complicaciones operatorias. Se realiza un análisis bivariado comparando las técnicas quirúrgicas: abierta versus laparoscópica. Se comparan proporciones con Chi cuadrado y promedios con U de Mann-Whitney. Resultados: 89 pacientes fueron incluidas en el estudio, 76 casos por técnica abierta (TA) y 13 casos por técnica de Burnia (TB). El promedio de edad fue 3.8 años, 5.05 días de hospitalización en TA unilateral y 2.3 días en TB unilateral (P=0.03), 7.2 días de hospitalización en TA bilateral y 2.25 días en TB bilateral (P=0.026). Tiempo quirúrgico 46.9 min en TA unilateral y 40.38 min en TB unilateral (P=0.232). Tiempo operatorio de 64.7 min en TA bilateral y 42.5 min en TB bilateral (P=0.038). Complicaciones 2 casos (2.6%) en TA y 1 caso (7.7%) en TB (P=0.35). Conclusiones: El uso de la técnica laparoscópica disminuyó los tiempos de estancia hospitalaria y tiempo quirúrgico cuando es bilateral. Desde el punto de vista estético las cicatrices fueron menos visibles en el tratamiento quirúrgico por abordaje de mínima invasión.

Introduction: At present, the debate is expanding on which technique would be better, comparing open surgery with the laparoscopic technique and the future cosmetic interest in female patients who require surgery, so the objective of the present study was to describe girls with inguinal hernia undergoing laparo-scopic correction techniques (Burnia technique) versus conventional surgery for inguinal hernias. Methods: The present observational study was carried out at the Dr. Roberto Gilbert Elizalde Children's Hospital, in Guayaquil, Ecuador, from January 2021 to February 2022. With a non-probabilistic sample, girls undergoing surgical treatment entered the study for inguinal hernia. Age, surgical technique, hospital stay, surgical time, and operative complications were recorded. Bivariate analysis is performed comparing the surgical techniques: open versus laparoscopic. Proportions are compared with Chi-square and means with Mann-Whitney U. Results: 89 patients were included in the study, 76 cases by open technique (AT) and 13 cases by Burnia technique (TB). The average age was 3.8 years, 5.05 days of hospitalization in unilateral TA and 2.3 days in unilateral TB (P=0.03), 7.2 days of hospitalization in bilateral TA, and 2.25 days in bilateral TB (P=0.026). Surgical time was 46.9 minutes in unilateral TA and 40.38 minutes in unilateral BT (P=0.232). Operative time of 64.7 min in bilateral TA and 42.5 min in bilateral TB (P=0.038). Complications 2 cases (2.6%) in TA and 1 case (7.7%) in TB (P=0.35). Conclusions: Using the laparoscopic technique decreased hospital stay times and surgical time when it is bilateral. From the aesthetic point of view, the scars were less visible in the minimally invasive surgical treatment.

Quiste del rafe medio perineal / Median raphe cysts of the perineum

Introducción: los quistes de rafe medio (QRM) son lesiones infrecuentes del aparato genital masculino, pueden localizarse desde la parte distal del pene hasta la zona perianal. Se deben a defectos del cierre del rafe medio durante el desarrollo embrionario. Objetivo: presentar un lactante con el diagnóstico de QRM, discutir el diagnóstico, tratamiento y seguimiento. Caso clínico: niño de 1 año y 3 meses de edad con 7 lesiones quísticas de 0.5 cm cada una en el rafe medio escrotal desde el nacimiento, la ecografía de partes blandas reporta imagen sólida hipoecogénica de borde definidos y sin vascularización al doppler. Se realizó exéresis quirúrgica y la patología confirmó el diagnóstico de quiste de rafe medio perineal, con buena evolución en el seguimiento. Discusión: 75% de los casos de los QRM son asintomáticos es por ello que muchas veces su diagnóstico es tardío, además su desconocimiento produce confusión con patologías quísticas o tumorales similares. El diagnóstico es clínico, aunque la ecografía puede ayudar para excluir otras anomalías como las vasculares. El tratamiento de elección debe ser la extirpación quirúrgica para evitar episodios de sobreinfección o molestias locales derivadas de su localización y tamaño. Conclusión: debido a lo infrecuente de esta patología es importante darla a conocer. Se recomienda realizar la valoración integral del paciente pediátrico para lograr un adecuado diagnóstico, ofrecer el mejor tratamiento y brindar información adecuada a los padres.

Introduction: median raphe cysts (MRC) are uncommon lesions of the male genitalia. They can be found anywhere from the distal penis to the perianal area. They are caused by an incomplete closure of the median raphe during embryologic development. Objective: to present a case of MRC in an infant and provide a review on diagnosis, treatment and follow-up. Case report: one year and three months old boy, with seven 0.5 cm sized cystic lesions along the scrotum median raphe, noticed since birth. A soft tissue ultrasound demonstrated a well-circumscribed hypoechogenic solid image without any evidence of vascularity at Doppler ultrasound. Surgical excision was conducted and histopathology confirmed the diagnosis of a median raphe cyst of the perineum, showing good progression in follow-up. Discussion: 75% of cases of MRC are asymptomatic, thus their diagnosis is often delayed. Not knowing this condition leads to confuse MRC with other similar cysts or tumors. The diagnosis is mostly clinical, although ultrasound may help to exclude other anomalies such as vascular anomalies. Surgical excision is the treatment of choice to prevent superinfection or local discomfort due to its location and size. Conclusion: Recognition of this uncommon pathology is imperative. A comprehensive evaluation of the pediatric patient is recommended to achieve an adequate diagnosis and treatment and provide appropriate information to the parents.

Restoration with implants in patients with recessive dystrophic epidermolysis bullosa and patient satisfaction with the implant-supported superstructure.

PURPOSE: The use of endosseous implants in the prosthetic restoration of edentulous patients with recessive dystrophic epidermolysis bullosa (RDEB) may provide improved outcomes when compared with traditional prosthetic methods. The aim of this study was to evaluate the feasibility of placing endosseous implants in patients with RDEB and to compare the treatment outcomes of fixed and removable implant-supported restorations in the edentulous maxilla or mandible with the main emphasis on patient response. MATERIALS AND METHODS: Six patients with RDEB were treated with implants. All patients were completely edentulous in either the maxilla or mandible and had marked oral involvement, with alterations in the soft and hard tissues in all cases. Three patients were treated with fixed, screw-retained implant-supported prostheses, and 3 were treated with removable implant-supported prostheses. Six months after prosthetic restoration, patients were given a questionnaire to assess their psychologic well-being and satisfaction with the implant-supported restoration marked on a visual analog scale. RESULTS: A total of 38 dental implants (21 maxillary, 17 mandibular) were placed in 6 patients. The implant success rate was 97.9%. The average follow-up from implant placement was 5.5 years (range, 1 to 9). The fixed and removable implant-supported prostheses were associated with improvements in comfort and retention, function, esthetics and appearance, taste, speech, and self-esteem. The level of satisfaction was slightly higher in patients with a fixed prosthesis. CONCLUSION: These findings suggest that endosseous implants can be successfully placed and provide support for prostheses in patients with RDEB. Patients with fixed prostheses and overdentures were satisfied with their implant-supported prostheses in the edentulous maxilla and mandible.

Complete fixed prostheses over implants in patients with oral epidermolysis bullosa.

PURPOSE: This study was conducted to evaluate the feasibility of placing fixed prostheses over endosseous implants in edentulous patients with recessive dystrophic epidermolysis bullosa. PATIENTS AND METHODS: Three cases of dental implants with fixed prostheses are presented. All 3 patients had marked oral involvement, with devastating alterations in the soft and hard tissues. The use of fixed prostheses avoids contact between the prosthesis itself and the oral mucosa, thus preventing the formation of blisters. RESULTS: A total of 27 implants (15 maxillary and 12 mandibular) were placed. One maxillary implant failed; the rest integrated successfully, allowing crown placement. The average follow-up after implant placement was 3 years (range, 1 to 5 years). CONCLUSIONS: Our findings suggest that endosseous implants are not contraindicated and can be placed successfully to improve these patients' quality of life. Implants can provide support for complete fixed prosthesis restoration in patients with epidermolysis bullosa. This procedure keeps the prosthesis from rubbing on the oral mucosa and prevents the development of ulcerations, improving mastication and esthetics.
