Colorectal cancer metastases to the thyroid gland: A case report.

BACKGROUND: Secondary malignancies of the thyroid gland are a rare finding in clinical practice. In addition, colorectal metastasis to the thyroid (CMT) is even more infrequently diagnosed. The source of the primary tumor follows demographic and ethnic patterns, which reflects the most prevalent malignancies in the different populations. Colorectal cancer is one of the most common types of cancer worldwide; nevertheless, CMT is infrequently diagnosed. Most of them are identified during the follow-up of gastrointestinal primary malignancies. Due to the improvement of image techniques, oncological treatment, and follow-up, survival and consequent diagnosis of metastatic disease are more frequent. Those facts make this entity a diagnostic and therapeutic challenge, due to the lack of information and the difficulties performing clinical trials and research. CASE SUMMARY: Here, we present a case report of a patient diagnosed with CMT of adenocarcinoma of the rectum evidenced during follow-up, 4 years after neoadjuvant chemoradiotherapy, who had subsequent curative surgical treatment of the primary tumor and inter-current lung bilateral metastases. CONCLUSION: Thyroid metastases of extra-thyroid origin are an uncommon finding, even rarer in cases of CMT. The diagnostic process, as well as survival of oncologic patients is improving, and consequently the number of metastases to the thyroid gland is increasing.

Fracturas de pelvis con hematoma retroperitoneal asociado: tiempo hasta la angioembolización y resultados / Pelvic fractures with associated retroperitoneal hematoma: time until angioembolization and results

Introducción: El tratamiento de las fracturas de pelvis con hematoma retroperitoneal (HRP) es controvertido. Especialmente la necesidad de angioembolización (AE) cuando no hay extravasación de contraste (EC) en la tomografía computarizada (TC) o angiografía. Otro aspecto relevante es el retraso hasta la misma. Nuestro objetivo ha sido determinar si existen diferencias en el tiempo hasta la AE entre los pacientes admitidos durante el horario laboral y los admitidos fuera del mismo y durante los fines de semana y festivos. Nuestra hipótesis era que la angiografía y AE serían más frecuentes en el horario laboral, y el tiempo hasta las mismas sería superior fuera del horario laboral habitual, con una mortalidad mayor en este grupo para una gravedad global similar. Un objetivo secundario ha sido valorar la correlación entre EC en la TC y la angiografía. Métodos: Análisis retrospectivo de 2 cohortes de pacientes con HRP por fractura de pelvis. Se estudia la realización de angiografía dividiendo a los pacientes según su hora de llegada a lo largo de un periodo de 24 años (grupo A: horario laboral, y grupo B: fuera del mismo). La indicación de angiografía y AE fue realizada por la guardia de cirugía general, en consenso con el radiólogo intervencionista. Se han analizado variables demográficas, mecanismo lesivo, lesiones asociadas, gravedad fisiológica y anatómica, EC en la TC y la angiografía, necesidad de AE, estancia en unidad de cuidados intensivos (UCI) y mortalidad. Resultados: Se admitió a 104 pacientes con diagnóstico de HRP por fractura pélvica. Se realizó angiografía, con AE en 63 casos (61%). Los grupos eran comparables en las variables analizadas. En el 70% de los pacientes del grupo A se realizó angiografía, frente al 57% del grupo B, sin diferencias en tiempo hasta la AE. Se demostró EC en la TC en 53 de los 96 pacientes en los que se hizo, lo que se confirmó mediante angiografía en el 85%. No hubo diferencias estadísticamente significativas de mortalidad entre ambos grupos. Conclusiones: Se demuestra un tiempo corto entre la admisión en Urgencias y la AE, sin relación con el momento del ingreso durante el día, y una buena correlación entre la EC en la TC y la angiografía

Introduction: Two areas of controversy in the management of bleeding pelvic fractures are the need to perform angioembolization (AE) in patients with a retroperitoneal hematoma (RPH) but no contrast extravasation (CE) on Computerized Tomography (CT) and/or angiography, and the delay to AE. Our main objective was to assess whether there had been differences in the percentage and delay to AE between patients admitted on weekdays versus off-hours (weekends and admission after 3pm) at our hospital. Our hypothesis was that angiography and AE would be more frequent on weekdays, and the time delay would be longer during off-hours, with a higher mortality in this latter group for a similar overall severity. A secondary objective was to assess the correlation between CE on CT scan and angiography. Methods: Retrospective review of two cohorts of patients with RPH from a pelvic fracture during a period of 24 years. Patients were divided depending on the time of arrival (Group A: weekdays, and Group B: off-hours). The decision to perform angiography and AE was made by the general surgeons on call, in consensus with the interventional radiologist. We analyzed demographics, mechanism of injury, associated injuries, physiologic and anatomic trauma scores, CE on CT scan, need of AE, Intensive Care Unit (ICU) stay and mortality. Results: 104 patients were admitted with RPH from a pelvic fracture. We performed AE in 63 cases (61%). The groups were comparable in the variables analyzed. In 70% of patients in group A, angiography was done, vs 57% in group B, with the same median time delay. CE on CT scan was seen in 53 out of 96 patients and confirmed by angiography in 45 (85%) of them. No significant differences were found in mortality between the two groups. Conclusions: There was a short delay from admission to AE, even during off-hours, and a good correlation of CE on CT scan and angiography

Tasa de conversión y morbilidad en el abordaje laparoscópico en pacientes seleccionados con obstrucción intestinal adherencial / Morbidity and Conversion Rate in Laparoscopy Approach in Selected Patients with Adhesive Intestinal Obstruction

Introducción: El síndrome adherencial es la causa más frecuente de obstrucción de intestino delgado. La laparotomía es el abordaje estándar. El avance de la cirugía mínimamente invasiva hace posible la resolución de cuadros obstructivos por laparoscopia. Objetivo: Analizar el abordaje laparoscópico de la obstrucción intestinal y compararlo con la vía abierta. Método: Análisis retrospectivo de los pacientes tratados de obstrucción intestinal aguda mediante laparoscopia en nuestro hospital desde 2012 hasta 2016. Se utilizó como referencia un grupo de pacientes tratados desde 2002 hasta 2005, cuando sólo se usaba el abordaje abierto. Se analizaron datos demográficos, riesgo quirúrgico, comorbilidades, métodos diagnósticos y complicaciones (Clavien). Resultados: De los 134 pacientes intervenidos de obstrucción intestinal aguda, se inició un abordaje laparoscópico en 47 (35 pr ciento). Por esta vía sólo se completaron 32 pacientes (68 por ciento). La tasa de conversión fue del 32 por ciento, estos pacientes fueron eliminados del estudio. En el grupo de referencia se analizaron al azar 32 pacientes. Ambos grupos son comparables. El grupo tratado con abordaje laparoscópico tuvo un 9 por ciento de complicaciones y un 3 por ciento de reintervenciones, con una sola lesión inadvertida. El grupo laparoscópico tuvo un 12,5 por ciento de reintervenciones, todas por evisceración, pero tuvo una lógica mayor tasa de resecciones intestinales. No hubo mortalidad hospitalaria. Conclusión: Los resultados en los pacientes en que se ha completado la cirugía por laparoscopia se comparan favorablemente con los del abordaje abierto en un grupo histórico homogéneo de referencia, y sin el riesgo añadido de evisceración(AU)

Introduction: Adherence syndrome is the most frequent cause of small bowel obstruction. Laparotomy is the standard approach. The progress of minimally invasive surgery makes it possible to resolve obstructive frames by laparoscopy. Objective: To analyze the laparoscopic approach for intestinal obstruction and compare it with the open pathway. Method: Retrospective analysis of patients treated for acute intestinal obstruction by laparoscopy in our hospital, from 2012 to 2016. A group of patients treated from 2002 to 2005 were used as reference, when only the open approach was used. We analyzed demographic data, surgical risk, comorbidities, diagnostic methods and complications (Clavien). Results: Within the 134 patients operated for acute intestinal obstruction, a laparoscopic approach was started in 47 (35 percent). Only 32 patients (68 percent) were completed in this way. The conversion rate was 32 percent, these patients were eliminated from the study. In the reference group, 32 patients were randomly analyzed. Both groups are comparable. The group treated with laparoscopic approach had 9 por ciento complications and 3 percent reoperations, with a single unexpected lesion. The laparoscopic group had 12.5 of reintervention, all due to evisceration, but had a higher rate of intestinal resections. There was no hospital mortality. Conclusion: In patients who have completed laparoscopic surgery, the results are compared favorably with those of the open approach in a homogeneous historical reference group, and without the added risk of evisceration(AU)
