Endometriosis de la pared abdominal: estudio descriptivo de una serie de 21 casos / Abdominal wall endometriosis: A descriptive study of a series of 21 cases

Introducción. La endometriosis de la pared abdominal se define como la presencia de tejido endometrial en cualquiera de las capas que componen la pared abdominal. Su incidencia es baja y se caracteriza por un diagnóstico tardío. Materiales y métodos. Se trata de un estudio descriptivo y retrospectivo entre 2010 y 2014 en pacientes con endometriosis de la pared abdominal, cuyo análisis patológico fue realizado en un centro de ayudas diagnósticas de Medellín. Se identificaron las variables histopatológicas del reporte, y la información clínica mediante una entrevista telefónica suministrada por la paciente. Se analizaron los datos con medidas descriptivas de resumen. Resultados. Participaron 21 de 65 pacientes con diagnóstico de endometriosis de la pared abdominal. La media de edad al momento del diagnóstico fue de 35,3 años (desviación estándar, DE=8), el 71,4 % tenía el antecedente de cesárea y, el 38,1 %, el de endometriosis pélvica. El 95,2 % de las pacientes manifestaron dolor, de las cuales el 50 % lo percibió como constante con agudización cíclica y, el 40 %, como cíclico; además, el 90,5 % manifestó sensación de masa. La mediana del tiempo desde la aparición de la lesión hasta el diagnóstico, fue de 24 meses (RIQ=6-60). Solo en cuatro pacientes se hizo el diagnóstico prequirúrgico. El tratamiento fue quirúrgico en todas las pacientes y ocho (38,1 %) presentaron recidiva.Conclusiones. La endometriosis de la pared abdominal usualmente se manifiesta como masas dolorosas aso-ciadas con cicatrices quirúrgicas previas, generalmente de origen ginecológico y los síntomas empeoran con la menstruación. Es usual que su diagnóstico sea tardío y pocas veces se hace antes del estudio histopatológico. El tratamiento de elección es la resección quirúrgica, aunque no es despreciable el porcentaje de recidivas (AU)

Introduction: Abdominal wall endometriosis is defined by the presence of endometrial tissue in any of the layers that compose the abdominal wall. It has a low incidence and is characterized by a late diagnosis. Materials and Methods: A descriptive, ambispective study that included patients with abdominal wall endometriosis whose pathological analysis was performed in a diagnostic center in Medellín between 2010 and 2014. Histopathological variables of the report were identified, and clinical information was provided by the patient by a phone interview. They were analyzed with descriptive summary measures.Results: 21 patients with abdominal wall endometriosis of 65 identified participated. The mean age at diagnosis was 35.3 years ± 8, 71.4% had a prior caesarean section and 38.1% had pelvic endometriosis. 95.2% manifested pain, among them, 50% was perceived as constant with cyclical exacerbation, 40% cyclical; 90.5% manifested mass sensation. The median from the onset of the lesion to the diagnosis was 24 months (IQR 6-60). Only four patients had pre-surgical. The treatment was surgical in all patients and eight (38.1%) had recurrence.Conclusions: Abdominal wall endometriosis usually manifests through painful masses associated with previous surgical scars usually of gynecological origin and whose symptoms worsen with menstruation. Its diagnosis is usually late and it is rarely reached before the histopathological study. Management of choice is surgical resection, however, its percentage of recurrence is not negligible (AU)

Identification of clinically relevant phenotypes in patients with Ebstein anomaly.

BACKGROUND: Ebstein anomaly (EA) is a heterogeneous congenital heart defect (CHD), frequently accompanied by diverse cardiac and extracardiac comorbidities, resulting in a wide range of clinical outcomes. HYPOTHESIS: Phenotypic characterization of EA patients has the potential to identify variables that influence prognosis and subgroups with distinct contributing factors. METHODS: A comprehensive cross-sectional phenotypic characterization of 147 EA patients from one of the main referral institutions for CHD in Colombia was carried out. The most prevalent comorbidities and distinct subgroups within the patient cohort were identified through cluster analysis. RESULTS: The most prevalent cardiac comorbidities identified were atrial septal defect (61%), Wolff-Parkinson-White syndrome (WPW; 27%), and right ventricular outflow tract obstruction (25%). Cluster analysis showed that patients can be classified into 2 distinct subgroups with defined phenotypes that determine disease severity and survival. Patients in cluster 1 represented a particularly homogeneous subgroup with a milder spectrum of disease, including only patients with WPW and/or supraventricular tachycardia (SVT). Cluster 2 included patients with more diverse cardiovascular comorbidities. CONCLUSIONS: This study represents one of the largest phenotypic characterizations of EA patients reported. The data show that EA is a heterogeneous disease, very frequently associated with cardiovascular and noncardiovascular comorbidities. Patients with WPW and SVT represent a homogeneous subgroup that presents with a less severe spectrum of disease and better survival when adequately managed. This should be considered when searching for genetic causes of EA and in the clinical setting.
