RESUMENLa Hernia de Littré es una patología rara de incidencia desconocida. Su sospecha clínica es infrecuente dada la inespecificidad de la sintomatología con la que debuta, por lo que su diagnóstico suele realizarse intraoperatoriamente. Se presenta el caso de un paciente con cuadro clínico de dolor abdominal agudo, masa no reductible y dolorosa en región inguinoescrotal derecha, a quien desde el ingreso se sospecha que presenta una hernia estrangulada. Tras una intervención quirúrgica de urgencia se realiza hallazgo intraoperatorio de hernia de Littré perforada. El paciente fue dado de alta en su sexto día postoperatorio en buenas condiciones generales.Palabras Clave: Hernia, Littré, divertículo de Meckel, Cirugía.
A 2-year-old boy presented with pneumonia and an abdominal mass was noted incidentally. A right lobe hepatic mass classified as PRETEXT III and congenital absence of the portal vein with drainage of the superior mesenteric vein to the inferior vena cava (Abernethy malformation type I) were confirmed by computed tomography and angiography. After a clinical diagnosis of hepatoblastoma had been made, he was treated with 4 cycles of doxorubicin and cisplatin and hepatic arterial chemoembolization with doxorubicin, after which the tumor was classified as POSTEXT III. He underwent a right extended hepatic lobectomy with resection of the caudate lobe but died on postoperative day 4 due to hepatic failure. The Abernethy malformation type I is associated with the development of hepatic tumors, and the abnormal blood flow might predispose to hepatic failure after liver resection. Extensive study of the hepatic vasculature is warranted in patients with suspected malformations. Liver transplant could be considered in patients with congenital portosystemic shunt and malignant liver tumors.
Background:Thyroid gland malignancies are rare in pediatric patients (0.7% of tumors); only 1.8% are observed in patients aged <20 years, with a higher prevalence recorded in women and adolescents. Risk factors include genetic syndromes, MEN disorders, autoimmune diseases, and exposure to ionizing radiation. Radiotherapy is also associated with an increased risk of secondary thyroid cancer. This study describes the clinical features and surgical outcomes of primary and secondary thyroid tumors in pediatric patients.MethodsInstitutional data were collected from eight international surgical oncology centers for pediatric patients with thyroid cancer between 2000 and 2020. Statistical analyses were performed using the GraphPad Prism software.ResultsAmong 255 total cases of thyroid cancer, only 13 (5.1%) were secondary tumors. Primary thyroid malignancies were more likely to be multifocal in origin (odds ratio [OR] 1.993, 95% confidence interval [CI].7466–5.132, p = 0.2323), have bilateral glandular location (OR 2.847, 95% CI.6835–12.68, p = 0.2648), and be metastatic at first diagnosis (OR 1.259, 95% CI.3267–5.696, p > 0.999). Secondary tumors showed a higher incidence of disease relapse (OR 1.556, 95% CI.4579-5.57, p = 0.4525) and surgical complications (OR 2.042, 95% CI 0.7917–5.221, p = 0.1614), including hypoparathyroidism and recurrent laryngeal nerve injury. The overall survival (OS) was 99% at 1 year and 97% after 10 years. No EFS differences were evident between the primary and secondary tumors (chi-square 0.7307, p = 0.39026).ConclusionsThis multicenter study demonstrated excellent survival in pediatric thyroid malignancies. Secondary tumors exhibited greater disease relapse (15.8 vs. 10.5%) and a higher incidence of surgical complications (36.8 vs. 22.2%).

Conclusions: This multicenter study demonstrates excellent survival for pediatric thyroid malignancy. Secondary tumors exhibit greater disease relapse (15.8% vs 10.5%) and a higher incidence of surgical related complications (36.8% vs 22.2%).
