Obscure digestive bleeding.

A 50-year-old woman presented to the emergency department with several episodes of melena in the last week. The patient was not hemodynamically compromised and was conservatively managed. Urgent upper gastrointestinal endoscopy and colonoscopy showed no source of bleeding. Abdominal CT demonstrated three mural nodular lesions up to 2cm in the mid jejunum with hypervascular characteristics in arterial phase without active bleeding in venous phase. Angiography (Figure 1A) revealed three tumours with neo-angiogenesis and no active bleeding. Each lesion was stained with methylene blue and followed by embolization with coils. Exploratory laparotomy (Figure 1B) showed the three nodules marked by angiography. Intestinal resection of the affected segment was performed. Histopathological study proved the diagnosis of suspicion (Figure 2).

Uso de sonda nasogástrica en pacientes sometidos a esofaguectomía: ¿Un gesto innecesario? / Nasogastric tube utilization after esophagectomy: an unnecessary gesture?

INTRODUCCIÓN: El empleo de una sonda descompresiva nasogástrica es aceptado como uno de los cuidados perioperatorios básicos tras una cirugía de resección esofágica. Sin embargo, con el desarrollo de los programas de rehabilitación multimodal en este campo y sin una evidencia clara que sustente su empleo, la indicación sistemática de dicha medida puede resultar controvertida. MATERIAL Y MÉTODOS: Estudio retrospectivo, descriptivo y comparativo de los casos intervenidos de esofaguectomía tipo Ivor-Lewis en nuestro centro desde enero de 2015 hasta diciembre de 2018 con colocación (Grupo S) o no de sonda (Grupo N) descompresiva en la plastia gástrica durante el postoperatorio. Se evaluaron variables epidemiológicas y diferencias entre los grupos en morbimortalidad postquirúrgica, estancia hospitalaria, inicio de la tolerancia oral y la necesidad de colocación de sonda nasogástrica. RESULTADOS: Un total de 43 pacientes fueron incluidos en este estudio con una mediana de edad de 61 años, siendo el 86% varones. El 46,5% eran hipertensos, el 25,5% presentaban enfermedad pulmonar y el 16,3% padecían diabetes mellitus. La mediana del tiempo de estancia hospitalaria fue de nueve días en el grupo S frente a 11,5 días del grupo N, sin diferencias en el inicio de la tolerancia oral. La tasa de dehiscencia anastomótica fue del 5% y del 0%, respectivamente. La mortalidad global fue del 2,3% en los primeros 90 días, sin diferencias entre los grupos y la necesidad de colocación de la sonda durante el postoperatorio se produjo únicamente en un paciente (4,3%) del grupo N. CONCLUSIONES: La no utilización de sonda nasogástrica durante el postoperatorio de una esofaguectomía tipo Ivor-Lewis es una medida segura y no está asociada a mayor número de complicaciones ni estancia hospitalaria, pudiendo mejorar la comodidad y la recuperación postoperatoria del paciente

INTRODUCTION: Nasogastric decompressive tube utilization has been accepted as one of the basic perioperative care measures after esophageal resection surgery. However, with the development of multimodal rehabilitation programs and without clear evidence to support their use, the systematic indication of this measure may be controversial. MATERIAL AND METHODS: Retrospective, descriptive and comparative study of patients who had undergone Ivor-Lewis esophagectomy in our center -from January 2015 to December 2018- with placement (Group S), or without placement (Group N) of a decompressive tube in gastroplasty during postoperative period. Epidemiological variables and differences between groups in post-surgical morbidity and mortality, hospital stay, onset of oral tolerance and the need for nasogastric tube placement were evaluated. RESULTS: A total of 43 patients were included in this study, with a median age of 61 years, being 86% male. 46.5% were hypertensive, 25.5% had lung disease and 16.3% had diabetes mellitus. The median length of hospital stay was 9 days in group S versus 11.5 days in group N, with no differences in the onset of oral tolerance. Anastomotic dehiscence rate was 5% and 0% respectively. The overall mortality was 2.3% in the first 90 days, without differences between the groups. Placement of nasogastric tube during postoperative period was required only in 1 patient (4.3%) of the group N. CONCLUSIONS: Non-use of nasogastric tube during postoperative period of an Ivor-Lewis esophagectomy is a safe measure, as it is not associated with a higher rate of complications or hospital stay. This fact may be able to improve patients' comfort and postoperative recovery

Etiología de la mastitis crónica: propuesta de secuencia diagnóstica / Proposed diagnosis sequence for chronic mastitis aetiology

Introducción: Las lesiones inflamatorias mamarias precisan con frecuencia de estudio histopatológico por su capacidad de imitar a los tumores mamarios malignos. El objetivo es proponer una secuencia diagnóstica de las inflamaciones mamarias benignas crónicas. Material y método: Se han revisado en la literatura los métodos y algoritmos diagnósticos de las mastitis crónicas. Resultados: Se propone un algoritmo diagnóstico para los procesos inflamatorios crónicos mamarios. Requiere determinar el patrón histopatológico inflamatorio y su localización, así como un estudio microbiológico apropiado. Posteriormente puede precisar de nuevas pruebas bioquímicas y serológicas orientadas por una correlación clinicopatológica para establecer un diagnóstico específico. Discusión: No se han identificado en la literatura otros algoritmos diagnósticos avalados por estudios de alto nivel de evidencia. Los patrones histopatológicos no son uniformes. Conclusiones: El diagnóstico etiológico precisa identificar patrones histopatológicos inflamatorios benignos y su localización, un estudio microbiológico y pruebas orientadas por correlación clinicopatológica. Se precisan estudios de investigación con niveles de evidencia altos

Introduction: Inflammatory breast lesions require histopathological study due to their ability to clinically and radiologically mimic malignant mammary tumours. The objective is to propose a diagnostic technique for benign chronic inflammatory processes of the breast. Material and methods: We reviewed the literature on the diagnostic methods used in chronic mastitis. Results: We propose a diagnostic algorithm for chronic inflammatory processes of the breast. The aetiological diagnosis requires identifying benign inflammatory histopathologic patterns and locations, and microbiological study. New biochemical and serological tests oriented by clinicopathological correlation may then be required to establish a specific diagnosis. Discussion: No diagnostic algorithms based on studies with a high level of evidence have been identified. No uniformity in histopathologic patterns has been described. Conclusions: The etiologic diagnosis requires identifying benign inflammatory histopathologic patterns and locations, microbiological study and tests oriented by clinicopathological correlation. There is a lack of studies with a high level of evidence

Rotura espontánea de aneurisma de la arteria esplénica / Spontaneous rupture of an aneurysm in the splenic artery

Introducción. Los aneurismas de la arteria esplénica son lesiones vasculares infrecuentes, aunque representanel 60% de todos los aneurismas viscerales. Suelen ser clínicamente asintomáticos, pero en caso de rotura espontánease manifiestan como un cuadro de abdomen agudo y shock, requiriendo un diagnóstico temprano y una actitud quirúrgicainmediata. Caso clínico. Varón de 64 años de edad con una rotura de un aneurisma de la arteria esplénica que precisóintervención quirúrgica urgente con su resección y esplenectomía

Introduction. Aneurysms in the splenic artery are rare vascular lesions, although they account for 60% of allvisceral aneurysms. They are usually clinically asymptomatic, but when spontaneous rupture occurs they manifest in theform of acute symptoms in the abdomen and shock, and therefore require an early diagnosis and immediate surgicalintervention. Case report. A 64-year-old male with a ruptured aneurysm in the splenic artery that required urgent surgeryto excise it and a splenectomy

Evidencia de la alimentación enteral precoz en la cirugía colorrectal / No disponible

los pacientes intervenidos de cirugía colorrectal, incluso en muchasocasiones estos pacientes se mantienen con sonda nasogástricaen el postoperatorio, con el supuesto de prevenir complicacionescomo la dehiscencia, evisceración o eventración.Realizamos una revisión de la evidencia clínica sobre el empleode sonda nasogástrica y alimentación precoz consultando las basesdel PubMed, Embase y la Cochrane.Encontramos evidencia Ia, Ib a partir de meta-análisis y estudiosrandomizados prospectivos donde se desaconseja el uso sistemáticode la sonda de descompresión gástrica y se recomienda elinicio de una alimentación precoz en la cirugía colorrectal. La dietaabsoluta no aporta ningún beneficio después de una cirugíagastrointestinal y con la sonda nasogástrica no disminuyen lascomplicaciones postoperatorias. Sin embargo, una cirugía menosinvasiva y los avances en la anestesia y analgesia contribuyen a reducirel íleo postoperatorio
