Introduction: Colorectal cancer has become the third cancer worldwide in terms of incidence and fourth in mortality. At diagnosis approximately 25% of patients will have liver metastases. With adequate treatment, the prognosis of stage IV patients reaches a survival of 40% at 5 years. We want to evaluate the response of the primary tumor of the colon from imaging and anatomopathological point of view in patients with colorectal cancer with liver metastases treated with chemotherapy and who then went to colon resection. Materials and Method: It is a retrospective and descriptive study of patients with stage IV colorectal cancer. The inclusion criteria were that they had cancer of the colon or upper rectum, with synchronous liver metastases, who have received at least 4 cycles of neoadjuvant chemotherapy and that subsequently went to resection of the primary tumor. Results: We recruited 9 patients, 4 men and 5 women. All received 4 or more cycles of chemotherapy prior to primary surgery. Of these, 8 had imaging control after chemotherapy. According to RECIST criteria, 3 patients presented complete response, 1 patient partial response and 4 stable disease. The anatomopathological study of the resected colon showed a macroscopic tumor disappearance in 2 patients, and microscopic in 1 patient. Conclusions: The complete pathological regression in our cases treated with neoadjuvant chemotherapy is a rare occurrence. This allows us to indicate the resection of the colorectal tumor site in all these cases.

Introduction: the development of sparing techniques with sphincter preservation with ade-quate surgical and oncological results has allowed to offer the patient the sphincter apparatus preservation, avoiding the definitive colostomy, however, these techniques may present secondary incontinence to the loss of the rectum. Both surgical options can affect the quality of life of the patient and this element should be considered. Objective: To compare the change in quality of life of patients undergoing APR vs sphinc ter preserving techniques in patients operated for rectal cancer. Materials and Method: Cross-sectional cohort study with medium-low rectal cancer patients, operated in our hospital from 2009 to 2015. The instrument EuroQuol-5D2, validated in chilean spanish is used. Results: 39 patients were included (11 definitive colostomy and 28 sphincter preservation). In the analysis by domains, significant differences were observed favor to definitive colostomy in the Item of “Habitual Activities” and favor to sphincter preservation in the Item “Sexuality”. Conclusions: In patients with middle-low rectal cancer, the choice of surgical technique have a measurable impact on the patient’s quality of life.

Introduction: Hemorrhagic cholecystitis is a rare complication of acute cholecystitis with a high mortality. Materials and Method: Patient with abdominal pain in right hypochondrium and jaundice. Laboratory analyses and hepatobiliary ultrasound suggested acute cholecystitis, however, general worsening during hospital stay was observed and a computed tomography was performed, revealing hemorrhagic cholecystitis and hemoperitoneum. Results: Urgent laparotomy which confirmed tomographic results, successfully solved with cholecystectomy. Discussion: Hemorrhagic cholecystitis diagnosis is difficult as symptoms at the beginning do not differ from acute cholecystitis, then, clinical suspicion and a correct image analysis is crucial for its detection. Conclusion: Although, perforated hemorrhagic cholecystitis with hemoperitoneum is a very rare entity with confused diagnosis, an abdominal computed tomography with intravenous contrast is very important in any patient with severe acute cholecystitis suspicion.

Introduccion: El doble arco aortico (DAA) es una malformacion cardiovascular infrecuente caracterizada por la persistencia de ambos arcos aorticos posterior al nacimiento. Puede presentarse con rama derecha dominante (70-73%), izquierda o simetrica. Su forma anatomica produce compresion de estructuras mediastinicas como la traquea y esofago. Caso clinico: Lactante menor hombre de 3 meses, con antecedente de estridor desde nacimiento. Ingreso a nuestro centro por neumonia grave con necesidad de ventilacion mecanica prolongada. Evaluado por otorrinolaringologia, se realizo revision de via aerea, observando estenosis en los ultimos 5 anillos traqueales con colapso dinamico de la traquea. La tomografia computada de torax demostro DAA completo con emergencias de troncos supraaorticos de ambos arcos de forma simetrica. Se decidio tratamiento quirurgico a la brevedad. Se abordo por toracotomia anterolateral izquierda, se realizo control vascular y seccion del arco aortico izquierdo distal a emergencia de subclavia, con plastia de aorta y arteria subclavia izquierda, liberado el arco aortico se realizo pexia y diseccion de tejido fibrotico que rodeaba traquea y esofago. Paciente evoluciono favorablemente, con resolucion de cuadro respiratorio y ausencia estridor. Fibrobroncoscopia postoperatoria no observo compresion traqueal. El alta hospitalaria fue al 14o dia postoperatorio. Actualmente a seis meses de seguimiento se encuentra asintomatico respiratorio y cardiovascular. Discusion: El DAA puede afectar al 0.03% de la poblacion pediatrica. Usualmente es sintomatico con manifestaciones obstructivas como estridor o disfagia por compresion de estructuras mediastinicas, por lo que requiere alta sospecha clinica para su confirmacion imagenologica y posterior tratamiento quirurgico.

El linfedema secundario de extremidades inferiores es la acumulacion de fluido rico en proteinas en el intersticio como consecuencia al dano de vasos linfaticos. En nuestro medio, se relaciona mas frecuentemente al tratamiento quirurgico del cancer. La incidencia varia dependiendo del tipo de cancer y el tratamiento recibido, existiendo mayor riesgo en los casos en los que se realiza linfadenectomia y radioterapia. El diagnostico clinico y a traves de tecnicas de imagenes es fundamental para evaluar el estado funcional del sistema linfatico. Los objetivos principales en el manejo del linfedema son limitar la morbilidad del paciente, mejorar la funcionalidad y la calidad de vida. Existen procedimientos que buscan prevenir el desarrollo del linfedema de extremidades inferiores. Una vez establecido, el tratamiento puede ser conservador y quirurgico. El tratamiento quirurgico incluye procedimientos fisiologicos (reconstructivos) y resectivos. El exito depende de una buena seleccion de los pacientes y la realizacion de un tratamiento individualizado. A continuacion se presenta una revision en cuanto a la incidencia, factores de riesgo, estrategias diagnosticas y tecnicas quirurgicas con enfasis en el tratamiento microquirurgico.
