Abstract Purpose: The benefits of laparoscopic approaches to treat colorectal cancer (CRC) and colorectal liver metastases (CRLM) separately are well established. However, there is no consensus about the optimal timing to approach the primary tumor and CRLM, whether simultaneously or staged. The objective of this review with practical reports is to discuss technical aspects required for patient selection to perform simultaneous laparoscopic approaches for CRC and CRLM. Methods: Literature review of oncological factors associated with patient selection for surgical treatment of CRLM and the use of laparoscopy in those cases, and report of technical aspects for simultaneous CRC and CRLM approaches. Results: Simultaneous laparoscopic resection has been successful in many series of selected patients, although it seems to be safer to perform minor and major liver resection with non-extended colorectal resections, and to avoid two high-risk procedures at the same time. Conclusions: Simultaneous CRC and CRLM resections seem to be safe when patients are carefully selected, also considering the risk of recurrence concerning oncologic outcomes. The pre-planning of simultaneous resection is mandatory to plan trocar positioning, procedure sequencing, and patient position.

RESUMO Objetivo O objetivo desse trabalho foi determinar a prevalência dos pacientes submetidos a procedimentos eletivos de coluna com mucosa nasal colonizada por Staphylococcus aureus Meticilina Resistente (MRSA). Métodos Foi realizado estudo retrospectivo dos prontuários de todos os pacientes submetidos a procedimentos eletivos, totalizando 125, entre 2015 e 2017, por dois cirurgiões de coluna do serviço de Ortopedia e Traumatologia do Hospital Mater Dei, de Belo Horizonte, Minas Gerais. A investigação pré-operatória para MRSA consistiu em swab nasal submetido à cultura microbiológica. Resultados Dos 125 pacientes avaliados, três (2,4%) apresentaram resultado positivo para colonização nasal por MRSA. Essa prevalência está de acordo com a literatura estrangeira, que varia de 1,5 a 5,9%. Desses pacientes, nenhum apresentou infecção da ferida operatória, provavelmente devido às medidas de profilaxia instituídas. Conclusão Apesar das limitações do estudo, constatamos que a população estudada apresenta prevalência de carreamento nasal de MRSA similar às populações estrangeiras. Nível de evidência III; Estudo Retrospectivo.

ABSTRACT Objective The objective of this study was to determine the prevalence of patients with colonization of methicillin-resistant Staphylococcus aureus (MRSA) in the nasal mucosa, who underwent elective spinal procedures. Methods Retrospective study of the medical records of all patients submitted to elective procedures, totaling 125 individuals in the period of 2015 and 2017, performed by two spinal surgeons of the Orthopedics and Traumatology Service of Hospital Mater Dei, Belo Horizonte, Minas Gerais. The pre-operative investigation of MRSA consisted of the collection of a nasal swab for microbiological culture. Results Of the 125 patients evaluated, three (2.4%) showed positive results for MRSA nasal colonization. This prevalence is consistent with the international literature, that ranges from 1.5 to 5.9%. Of these patients none had infection of the surgical wound, probably due to the preoperative prophylactic measures. Conclusions Despite the limitations of the study, we found that the prevalence of carriers of this nasal MRSA population is similar to that of populations worldwide . Level of evidence III; Retrospective Study.

RESUMEN El objetivo de este estudio fue determinar la prevalencia de pacientes con colonización de Staphylococcus aureus resistente a la meticilina (SARM) en la mucosa nasal que se sometieron a procedimientos electivos de columna vertebral. Métodos Estudio retrospectivo de los registros médicos de todos los pacientes sometidos a procedimientos electivos, con un total de 125 individuos en el período de 2015 a 2017, realizado por dos cirujanos de columna vertebral del Servicio de Ortopedia y Traumatología del Hospital Mater Dei, de Belo Horizonte, Minas Gerais. La investigación preoperatoria de SARM consistió en la recolección de un hisopo nasal para cultivo microbiológico. Resultados De los 125 pacientes evaluados, tres (2,4%) tuvieron resultados positivos para la colonización nasal por SARM. Esta prevalencia está de acuerdo con la literatura internacional, que varía de 1,5% a 5,9%. De estos pacientes, ninguno tuvo infección de la herida quirúrgica, probablemente debido a las medidas profilácticas preoperatorias. Conclusiones A pesar de las limitaciones del estudio, encontramos que la prevalencia de portadores de SARM nasal de esta población es similar a la de poblaciones de todo el mundo. Nivel de Evidencia III; Estudio retrospectivo.
