ABSTRACT

RESUMEN OBJETIVO: Presentar la experiencia de la unidad de mama de nuestro hospital con la utilización de la ecografía intraoperatoria en el tratamiento de las lesiones no palpables de mama. PACIENTES Y MÉTODO: Se incluyeron aquellas pacientes con lesiones no palpables de mama y ecovisibles. Intraoperatoriamente se localizó la lesión con la ecografía y se procedió a su exéresis, con comprobación ecográfica de su correcta extirpación con márgenes de seguridad. Se realizó estudio macroscópico en fresco de los márgenes marcados con tinta intraoperatoriamente. En caso de que los márgenes no fueran correctos se procedía a una ampliación de márgenes en el mismo acto quirúrgico. RESULTADOS: Desde el año 2012 se han intervenido 52 pacientes. En todas las pacientes se localizó la lesión con la ecografía. Se realizó tumorectomía a 24 pacientes y a 28 pacientes se les asoció la biopsia del ganglio centinela. El resultado patológico definitivo fue de 19 lesiones benignas y 33 lesiones malignas. A una paciente se le realizó mastectomía simple por presentar un carcinoma in situ extenso con microinfiltración no diagnosticado con las pruebas radiológicas preoperatorias. El resto de pacientes presentaron márgenes libres de tumor. CONCLUSIONES: La ecografía intraoperatoria es una técnica simple y fácil de desarrollar. Presenta una baja tasa de afectación de márgenes y es enteramente cirujano-controlada. Es confortable para el paciente y conlleva un bajo riesgo de complicaciones relacionadas con la técnica.


ABSTRACT OBJETIVE: To present the results of our hospital's experience with the utilization of intraoperative ultrasound in the treatment of non-palpable breast lesions. PATIENTS AND METHOD: We included those patients whose breast lesions were non-palpable yet simultaneously visible on ultrasound. The lesions were located intraoperatively with ultrasound and were removed with ultrasound verification of the proper security margins. An examination of the intraoperative macroscopic margins with ink was done. In cases with incorrect margins, a re-excision was done utilizing the same technique but with amplified margins. RESULTS: Dating from 2012, we have operated on 52 patients. In all cases, the lesions were discovered and localized by means of ultrasound. Lumpectomy was performed on 24 patients and we associated the sentinel node biopsy in 28 cases. Subsequent pathology reports determined that 19 lesions were benign and 33 lesions were malignant. There was one patient with a mastectomy because a long extensive ductal carcinoma in situ with microinfiltration that was not seeing during the preoperative study. CONCLUSIONS: Intraoperative ultrasound is an easy and simple technique that is entirely surgeon controlled and results in a low rate of positive margins. The procedure is comfortable for the patient and carries with it a low rate of complications.

ABSTRACT

BACKGROUND: Previous studies have shown a high prevalence of bronchiectasis in patients with moderate to severe COPD. However, the factors associated with bronchiectasis remain unknown in these patients. The objective of this study is to identify the factors associated with bronchiectasis in patients with moderate to severe COPD. METHODS: Consecutive patients with moderate (50% < FEV(1) ≤ 70%) or severe (FEV(1) ≤ 50%) COPD were included prospectively. All subjects filled out a clinical questionnaire, including information about exacerbations. Peripheral blood samples were obtained, and lung function tests were performed in all patients. Sputum samples were provided for monthly microbiologic analysis for 6 months. All the tests were performed in a stable phase for at least 6 weeks. High-resolution CT scans of the chest were used to diagnose bronchiectasis. RESULTS: Ninety-two patients, 51 with severe COPD, were included. Bronchiectasis was present in 53 patients (57.6%). The variables independently associated with the presence of bronchiectasis were severe airflow obstruction (OR, 3.87; 95% CI, 1.38-10.5; P = .001), isolation of a potentially pathogenic microorganism (PPM) (OR, 3.59; 95% CI, 1.3-9.9; P = .014), and at least one hospital admission due to COPD exacerbations in the previous year (OR, 3.07; 95% CI, 1.07-8.77; P = .037). CONCLUSION: We found an elevated prevalence of bronchiectasis in patients with moderate to severe COPD, and this was associated with severe airflow obstruction, isolation of a PPM from sputum, and at least one hospital admission for exacerbations in the previous year.

ABSTRACT

OBJECTIVES: We report a new case of severe renal trauma with significant active bleeding and urinary tract lesion in a hemodynamically stable patient, emphasizing the option of conservative treatment with selective embolization of the bleeding segmentary renal arteries, and stenting of the urinary tract with retrograde insertion of a JJ stent; thus avoiding emergency surgery associated with a high risk of nephrectomy. We review the indications of this therapeutic option. METHODS: Embolization of bleeding segmentary renal arteries and retrograde insertion of a JJ stent in a 24 year old patient presenting with severe renal trauma after motorbike motor vehicular accident. Patient remained hemodynamically stable during the whole diagnostic and therapeutic process. Good clinical outcome after 72 hours of ICU control and 18 days of admission in the Urology ward. RESULTS: After selective embolization bleeding stopped immediately; significative hematoma resorption and urinary fluid collection disappearance was seen during a 3 week hospital admission. There were not either immediate or deferred complications, being both renal function and blood pressure normal after 18 months follow up. CONCLUSION: Embolization of the bleeding segmentary renal arteries after severe renal trauma in hemodynamically stable patients is a therapeutic option that allows avoiding emergency surgery, which is associated with high risk for nephrectomy. Urinary tract stenting is enough for a good outcome of the pyelocalicilar system.

ABSTRACT

OBJETIVOS: Aportamos un nuevo caso de traumatismo renal severo con importante sangrado activo y lesión de la vía excretora en paciente hemodinámicamente estable, resaltando la posibilidad de tratamiento conservador con la embolización selectiva de las arterias segmentarias renales sangrantes y tutorización de la vía excretora con catéter doble J retrógradamente, evitando la cirugía urgente con alto riesgo de nefrectomía. Revisamos las indicaciones de esta alternativa terapéutica. METODO: Embolización selectiva de las arterias segmentarias renales sangrantes y colocación de doble J vía retrógrada, tras Las lesiones en general aparecen después de algunas horas de haber ingerido el fármaco causal y se resuelven espontáneamente en el curso de varias semanas. Las reincidencias tendrán lugar exactamente en los mismos sitios si el paciente vuelve a ingerir el mismo fármaco. Este tipo de reincidencia en los mismos sitios por lo general es el rasgo clínico que orienta hacia el diagnóstico correcto (3).El tratamiento consiste en averiguar el tipo de fármaco que origina la reacción medicamentosa y evitarlo. En manifestaciones graves o más generalizadas en el resto del tegumento cutáneo es aconsejable la utilización de corticoides tópicos y por vía general (1). traumatismo renal severo en paciente varón de 24 años de edad por accidente de motocicleta. El paciente permaneció hemodinámicamente estable durante todo el proceso diagnóstico y terapéutico. Control en UCI durante 72 h. y en sala de Urología durante 18 d. con buena evolución clínica. RESULTADOS: Cese inmediato del sangrado activo tras embolización selectiva, importante reabsorción del hematoma perirrenal y desaparición del urinoma durante las 3 semanas de estancia hospitalaria. No hubo complicaciones inmediatas ni diferidas, siendo la función renal y la tensión arterial normales tras un año y medio de seguimiento. CONCLUSION: La embolización selectiva de las arterias renales sangrantes tras un traumatismo renal severo, en pacientes hemodinámicamente estables, es una alternativa terapéutica que puede evitar la cirugía urgente con alto riesgo de nefrectomía. La tutorización de la vía urinaria es suficiente para la buena evolución de las lesiones del sistema pielocalicial (AU)

ABSTRACT

We report a case of small bowel obstruction in a 74-year-old woman presenting with abdominal pain due to the accidental swallowing of a snail shell. A diagnosis of obstruction was made by abdominal radiograph, and its etiology was found after abdominal CT was performed. This is an unusual case of small bowel obstruction due to a foreign body that was preoperatively diagnosed with imaging.
