Intestinal intussusception in adults: Location, causes, symptoms, and therapeutic management.

OBJECTIVE: Intestinal intussusception is difficult to diagnose in adults because the symptoms are nonspecific. However, most have structural causes that require surgical treatment. This paper reviews the epidemiologic characteristics, imaging findings, and therapeutic management of intussusception in adults. MATERIALS AND METHODS: This retrospective study identified patients diagnosed with intestinal intussusception who required admission to our hospital between 2016 and 2020. Of the 73 cases identified, 6 were excluded due to coding errors and 46 were excluded because the patients were aged <16 years. Thus, 21 cases in adults (mean age, 57 years) were analyzed. RESULTS: The most common clinical manifestation was abdominal pain, reported in 8 (38%) cases. In CT studies, the target sign yielded 100% sensitivity. The most common site of intussusception was the ileocecal region, reported in 8 (38%) patients. A structural cause was identified in 18 (85.7%) patients, and 17 (81%) patients required surgery. The pathology findings were concordant with the CT findings in 94.1% of cases; tumours were the most frequent cause (6 (35.3%) benign and 9 (64.7%) malignant). CONCLUSIONS: CT is the first-choice test for the diagnosis of intussusception and plays a crucial role in determining its aetiology and therapeutic management.

Invaginaciones intestinales en el adulto: localización, etiología, sintomatología y manejo terapéutico / Intestinal intussusception in adults: location, causes, symptoms, and therapeutic management

Objetivo: Las invaginaciones intestinales en adultos son de difícil diagnóstico debido a la inespecificidad de los síntomas. Sin embargo, la mayoría tienen una causa estructural que requiere tratamiento quirúrgico. El objetivo de este estudio es revisar sus características epidemiológicas, hallazgos en imagen y manejo terapéutico. Materiales y métodos: Estudio retrospectivo de las invaginaciones intestinales que precisaron ingreso hospitalario diagnosticadas en nuestro hospital entre 2016 y 2020. De un total de 73 casos fueron excluidos errores de codificación (n=6) y pacientes menores de 16 años (n=46), resultando 21 invaginaciones en adultos. Resultados: La edad media fue de 57 años, y el dolor abdominal fue la manifestación clínica más frecuente en el 38% de los casos (n=8). El diagnóstico mediante tomografía computarizada (TC), con la presencia “del signo de la diana”, alcanzó una sensibilidad del 100%, siendo la región ileocecal la localización más frecuente en un 38% de los pacientes (n=8). Un 85,7% de los casos (n=18) tenían una causa estructural y el 81% (n=17) requirió cirugía. Los resultados anatomopatológicos fueron concordantes con la TC en un 94,1%, siendo la etiología más frecuente la neoplásica: 35,3% benignas (n=6) y 64,7% malignas (n=9). Conclusiones: La TC es la prueba de elección en el diagnóstico de las invaginaciones intestinales y resulta determinante a la hora de identificar la etiología y decidir el manejo terapéutico.(AU)

Efectos de la pandemia por SARS-CoV-2 en una cohorte de pacientes con obstrucción venosa retiniana / Effects of the COVID-19 pandemic on a cohort of patients with vein occlusion

Antecedentes y objetivos En diciembre de 2019 surgió una nueva enfermedad por coronavirus en humanos causada por el virus SARS-CoV-2, la COVID-19, que se ha asociado con fenómenos trombóticos. La obstrucción venosa retiniana (OVR) es principalmente una consecuencia de los factores de riesgo vascular (FRV). El objetivo de este estudio ha sido analizar los casos de infección por SARS-CoV-2 en una cohorte de pacientes con OVR (cohorte Valdecilla). Pacientes y métodos Entre diciembre de 2008 y 2020 hemos atendido 429 pacientes con OVR. Diez han padecido COVID-19, de los que uno no presentaba FRV ni trombofilia. Los otros 9 fueron diagnosticados de OVR antes de la infección: todos tenían FRV; 6 ateromatosis carotídea y 4 presentaban un síndrome antifosfolípido. La infección no causó en ellos fenómenos trombóticos. Conclusiones La OVR es una manifestación infrecuente de la COVID-19. En nuestra cohorte de pacientes con OVR la COVID-19 no indujo eventos trombóticos (AU)

Background and objectives A new coronavirus disease in humans, COVID-19, caused by SARS-CoV-2, emerged in December 2019. It has been associated with the development of thrombotic phenomena. Retinal vein occlusion (RVO) is mainly a consequence of vascular risk factors (VRF). This study aimed to analyze cases of COVID-19 in a cohort of patients with RVO (Valdecilla cohort). Patients and methods Between December 2008 and December 2020, 429 patients with RVO were attended to in our clinic. Ten patients had COVID-19, one of which did not have VRF or thrombophilia. The remaining nine patients had RVO prior to the infection and VRF, six had carotid atherosclerosis, and four had antiphospholipid syndrome. The infection did not cause thrombotic phenomena in any of them. Conclusions RVO is a rare manifestation of COVID-19. In our cohort of patients with RVO, COVID-19 disease did not lead to thrombotic events (AU)
