    ResumenLas estenosis benignas de la v铆a biliar son debidas a lesi贸n de esta por manejo quir煤rgico, traumatismos o por inflamaci贸n. El manejo en la actualidad es por v铆a endosc贸pica mediante dilataciones, colocaci贸n de pr贸tesis pl谩sticas y m谩s recientemente con las pr贸tesis autoexpandibles totalmente cubiertas. Se presenta el caso de una menor de 7 a帽os a la que se realiz贸 trasplante de h铆gado y present贸 una estenosis a nivel de la col茅doco-col茅doco anastomosis en donde se utiliz贸 una pr贸tesis met谩lica totalmente cubierta autoexpandible con buenos resultados.AbstractBenign biliary strictures are due to injury by surgical operation, trauma or inflammation, is currently handling by endoscopy with dilation, placement of plastic stents and more recently with fully covered self-expanding prosthesis; the case of a child under 7 years that liver transplantation was performed and presented a stenosis at the level of the coledoco-coledoco anastomosis where a fully covered self-expandable metal stent was used with good results is presented

    Introducci贸n: La aplasia pulmonar es un raro trastorno del desarrollo pulmonar. Se caracteriza por la presencia de un bronquio principal rudimentario en ausencia de pulm贸n y arteria pulmonar. Generalmente se asocia con otros defectos cong茅nitos, y debe sospecharse ante la opacidad del hemit贸rax. Casos cl铆nicos: Se describen dos casos de pacientes con aplasia pulmonar diagnosticados en el Hospital Infantil de M茅xico Federico G贸mez en los 煤ltimos 5 a帽os. La primera paciente present贸 dificultad respiratoria desde el nacimiento. Se observ贸 radiopacidad total del hemit贸rax izquierdo, y se complet贸 el diagn贸stico de aplasia pulmonar con gammagraf铆a pulmonar y broncoscopia. La evoluci贸n ha sido insidiosa, con sintomatolog铆a respiratoria cr贸nica, dependencia de ox铆geno y neumon铆as recurrentes. La segunda paciente, de 5 a帽os de edad, permaneci贸 asintom谩tica durante los primeros 2 a帽os de vida. Fue hospitalizada por gastroenteritis infecciosa, y la radiograf铆a sugiri贸 hernia diafragm谩tica derecha. Se intervino y se encontr贸 eventraci贸n diafragm谩tica derecha y ausencia de pulm贸n ipsilateral. Se complet贸 el diagn贸stico con broncoscopia que mostr贸 bronquio principal derecho con saco ciego terminal. Conclusiones: La aplasia pulmonar es una entidad infrecuente. Debido a la variabilidad en la presentaci贸n cl铆nica debe tenerse un alto 铆ndice de sospecha ante el hallazgo de la radiopacidad total del hemit贸rax. Los m茅todos diagn贸sticos que se utilizan son radiograf铆a, tomograf铆a y gammagraf铆a. Para confirmar el diagn贸stico se requiere realizar broncoscopia. La escisi贸n del mu帽贸n y la traslocaci贸n diafragm谩tica se han descrito como opciones quir煤rgicas de tratamiento

    Tolerancia, seguridad y eficacia de la preparaci贸n intestinal con un d铆a de PEG3350 + bisacodilo en comparaci贸n con 2 d铆as de PEG3350 + bisacodilo en pacientes pedi谩tricos

    Introducci贸n: M煤ltiples preparaciones intestinales se han utilizado en ni帽os sometidos a una colonoscopia, con limitaci贸n variable debido a la aceptaci贸n, tolerancia y la limpieza adecuada. El objetivo del estudio fue comparar la tolerancia seguridad y eficacia de la preparaci贸n intestinal para colonoscopia de 1 d铆a con PEG 3350 (polietilenglicol) (4聽g/kg/d铆a) + bisacodilo y el tratamiento con 2 d铆as de preparaci贸n con PEG 3350 (2聽g/kg/d铆a) + bisacodilo en pacientes pedi谩tricos. M茅todos: Se realiz贸 un ensayo cl铆nico, aleatorizado y ciego. Se incluyeron pacientes de 2 a 18 a帽os, que ameritaron colonoscopia en forma programada. Los pacientes se asignaron de manera aleatoria en dos grupos: 1 d铆a de preparaci贸n con PEG 3350 4聽g/kg/d铆a + bisacodilo y 2 d铆as de preparaci贸n con PEG 3350 2聽g/kg/d铆a + bisacodilo. Por medio de un cuestionario, exploraci贸n f铆sica y valoraci贸n endosc贸pica (escala de Boston), se determin贸 la tolerancia, seguridad y eficacia de las 2 preparaciones a evaluar. Se realiz贸 una prueba t de Student para variables cuantitativas y 蠂2 para variables cualitativas. Resultados: No hubo diferencias significativas en las tasas de cumplimiento, los efectos adversos y la extensi贸n de la evaluaci贸n colonosc贸pica. Conclusiones: La tolerancia y seguridad entre la preparaci贸n intestinal para colonoscopia de 1 d铆a con PEG 3350 (polietilenglicol) (4聽g/kg/d铆a) + bisacodilo y la preparaci贸n de 2 d铆as con PEG 3350 (2聽g/kg/d铆a) + bisacodilo fue semejante. La calidad de la limpieza fue buena en ambos grupos, siendo parcialmente m谩s eficaz en el grupo de 1 d铆a con PEG 3350 (polietilenglicol) (4聽g/kg/d铆a)

    Complex ventral hernia secondary to giant omphalocele managed by preoperative pneumoperitoneum and botulinum toxin: A case report

    No full text
    Introduction: Post-omphalocele ventral hernias pose significant challenges in pediatric surgery, often requiring multiple revision surgeries and carrying a high morbidity rate. In this case report, we present the management of a pediatric patient with a complex ventral hernia and loss of domain resulting from a giant omphalocele. Case presentation: A 5-year-old female with a history of omphalocele managed with surgical skin closure at birth presented with a giant ventral hernia. The patient underwent a staged surgical correction that involved muscle paralysis using botulinum toxin (BT) injections, followed by progressive preoperative pneumoperitoneum (PPPP) as a pre-habilitation technique for abdominal wall closure, without the use of prosthetic materials or component separation. Conclusion: Our case demonstrates a successful alternative treatment approach, highlighting the reproducibility, effectiveness, and safety of using BT followed by PPPP in managing post-omphalocele ventral hernias in pediatric patients

    Objective Primary tracheobronchial tumors (PTTs) are rare heterogeneous lesions arising from any part of the tracheobronchial tree. Nonspecific symptoms may lead to delayed diagnosis that requires more aggressive surgical treatment. An analysis of cases collected by the International Network of Pediatric Airway Team was undertaken to ensure proper insight into the behavior and management of PTTs. Methods Patients <18 years of age with a histological confirmation of PTT diagnosed from 2000 to 2015 were included in this multicenter international retrospective study. Medical records, treatment modalities, and outcomes were analyzed. The patient presentation, tumor management, and clinical course were compared between malignant and benign histotypes. Clinical and surgical variables that might influence event-free survival were considered. Results Among the 78 children identified, PTTs were more likely to be malignant than benign; bronchial carcinoid tumor (n = 31; 40%) was the most common histological subtype, followed by inflammatory myofibroblastic tumor (n = 19; 25%) and mucoepidermoid carcinoma (n = 15; 19%). Regarding symptoms at presentation, wheezing (P = 0.001) and dyspnea (P = 0.03) were more often associated with benign growth, whereas hemoptysis was more frequently associated with malignancy (P = 0.042). Factors that significantly worsened event-free survival were age at diagnosis earlier than 112 months (P = 0.0035) and duration of symptoms lasting more than 2 months (P = 0.0029). Conclusion The results of this international study provide important information regarding the clinical presentation, diagnostic workup, and treatment of PTTs in children, casting new light on the biological behavior of PTTs to ensure appropriate treatments
