RESUMO
OBJECTIVE: Laparoscopic cholecystectomy (LC), despite its minimally invasive nature, requires effective control of post-operative pain. The use of local anesthetics (LA) has been studied, but the level of evidence is low, and there is little information on important parameters such as health-related quality of life (HRQoL) or return to work. The objective of the study was to evaluate the efficacy of 0.50% levobupivacaine infiltration of incisional sites in reducing POP after LC. METHODS: This was a prospective, randomized, double-blind study. Patients undergoing elective LC were randomized into two groups: no infiltration (control group) and port infiltration (intervention group). POP intensity (numerical rating scale, NRS), need for rescue with opioid drugs, PONV incidence, HRQoL, and return to work data, among others, were studied. RESULTS: Two hundred and twelve patients were randomized and analyzed: 105 (control group) and 107 (intervention group). A significant difference was observed in the NRS values (control group mean NRS score: 3.41 ± 1.82 vs. 2.56 ± 1.96) (p < 0.05) and in the incidence of PONV (31.4% vs. 19.6%) (p = 0.049). CONCLUSIONS: Levobupivacaine infiltration is safe and effective in reducing POP, although this does not lead to a shorter hospital stay and does not influence HRQoL, return to work, or overall patient satisfaction.
OBJETIVO: la colecistectomía laparoscópica (CL), a pesar de su carácter mínimamente invasivo, requiere un control efectivo del dolor postoperatorio (POP). El uso de anestésicos locales (AL) ha sido estudiado pero el nivel de evidencia es bajo y existe poca información acerca de parámetros relevantes como la calidad de vida relacionada con la salud (CVRS) o la reincorporación laboral. El objetivo de este estudio es analizar la eficacia de la infiltración de los sitios incisionales con levobupivacaína 0,50% en la reducción del dolor postoperatorio tras la CL. MATERIAL Y MÉTODOS: estudio prospectivo, aleatorizado y doble ciego. Pacientes sometidos a CL programada fueron aleatorizados en dos grupos: sin infiltración (grupo control) y con infiltración preincisional (grupo intervención). La intensidad del dolor (escala de puntuación numérica, NRS), la necesidad de rescates con opioides, la incidencia de náuseas o vómitos postoperatorios (NVPO) y datos de CVRS o reincorporación laboral, entre otros, fueron recogidos. RESULTADOS: 212 pacientes fueron aleatorizados y analizados: 105 en el grupo control y 107 en el grupo de intervención. Se observó una diferencia estadísticamente significativa en la intensidad del dolor (puntuación media NRS: 3.41 ± 1.82 vs. 2.56 ± 1.96) (p < 0.05) y en la incidencia de NVPO (31.4% vs. 19.6%) (p = 0.049). CONCLUSIONES: La infiltración con levobupivacaína es segura y efectiva en la reducción del dolor postoperatorio, aunque esto no conlleva una menor estancia hospitalaria y no influye en los resultados de CVRS, reincorporación laboral o satisfacción del paciente.

OBJECTIVE: We sought to assess the degree of antibiotic prophylaxis adequacy to our surgical antibiotic prophylaxis protocol among patients who underwent peripheral vascular bypass surgery. MATERIALS AND METHODS: Prospective cohort study. Adequacy to protocol was studied by comparing the different aspects of prophylaxis received by patients to those stipulated in the protocol in force at our hospital. Incidence of surgical wound infection was calculated and the effect of prophylaxis inadequacy on the incidence of surgical wound infection was estimated using the relative risk. RESULTS: The study covered 266 patients. Incidence of surgical site infection (SSI) after the follow-up period was 5.3% (95% Confidence interval [CI]: 3.0-9.4). Overall adequacy to the protocol of antibiotic prophylaxis was 91.0% (95% CI: 87.6-94.4). The most frequent cause of inadequacy to the protocol was time of initiation of antibiotic prophylaxis (94.1%). No relationship was found between SSI and antibiotic prophylaxis inadequacy (relative risk: 2.4; 95% CI: 0.49-12.5; p > 0.05). CONCLUSIONS: Global adequacy to protocol of antibiotic prophylaxis was high. The most frequent cause of inadequacy to the protocol was time of initiation of antibiotic prophylaxis.
OBJETIVO: Buscamos evaluar el grado de adecuación de la profilaxis antibiótica a nuestro protocolo de profilaxis antibiótica quirúrgica entre los pacientes sometidos a cirugía de bypass vascular periférico. MATERIAL Y MÉTODOS: Estudio de cohortes prospectivo. La adecuación al protocolo se estudió comparando los diferentes aspectos de la profilaxis recibida por los pacientes con los estipulados en el protocolo vigente en nuestro hospital. Se calculó la incidencia de infección de herida quirúrgica y se estimó el efecto de la inadecuación de la profilaxis sobre la incidencia de infección de herida quirúrgica mediante el riesgo relativo. RESULTADOS: El estudio abarcó 266 pacientes. La incidencia de infección del sitio quirúrgico (ISQ) tras el periodo de seguimiento fue del 5,3% (intervalo de confianza [IC] del 95%: 3,0-9,4). La adecuación global al protocolo de profilaxis antibiótica fue del 91,0% (IC 95%: 87,6-94,4). La causa más frecuente de inadecuación al protocolo fue el momento de inicio de la profilaxis antibiótica (94,1%). No se encontró relación entre ISQ e inadecuación de la profilaxis antibiótica (riesgo relativo: 2,4; IC 95%: 0,49-12,5; p > 0,05). CONCLUSIONES: La adecuación global al protocolo de la profilaxis antibiótica fue alta. La causa más frecuente de inadecuación al protocolo fue el momento de inicio de la profilaxis antibiótica.

Background: Surgical site infections (SSI) have an important impact on morbidity and mortality. Objective: This study, therefore, sought to assess the effect of a surgical care bundle on the incidence of SSI in colorectal surgery. Methods: We conducted a quasi-experimental intervention study with reference to the introduction of a surgical care bundle in 2011. Our study population, made up of patients who underwent colorectal surgery, was divided into the following two periods: 2007-2011 (pre-intervention) and 2012-2017 (post-intervention). The intervention's effect on SSI incidence was analyzed using adjusted odds ratios (OR). Results: A total of 1,727 patients were included in the study. SSI incidence was 13.0% before versus 11.6% after implementation of the care bundle (OR: 0.88, 95% confidence interval: 0.66-1.17, p = 0.37). Multivariate analysis showed that cancer, chronic obstructive pulmonary disease, neutropenia, and emergency surgery were independently associated with SSI. In contrast, laparoscopic surgery proved to be a protective factor against SSI. Conclusions: Care bundles have proven to be very important in reducing SSI incidence since the measures that constitute these protocols are mutually reinforcing. In our study, the implementation of a care bundle reduced SSI incidence from 13% to 11.6%, though the reduction was not statistically significant.

OBJECTIVE: The objective was to measure the incidence of surgical site infection (SSI) and identify risk factors, in patients undergoing elective surgery of the colon and rectum. MATERIALS AND METHODS: A prospective cohort study was performed from January 2017 to December 2018. RESULTS: A total of 130 patients were studied. The cumulative incidence of SSI was 12.3%. The 56.25% were superficial wound infections and the 31.25%, organ-space infection. The risk factors significantly associated with SSI were the non-administration of pre-operative oral nutrition, diabetes mellitus, heart disease, symptomatic state at the diagnosis of colorectal cancer (CRC), and ≥ 2 altered nutritional biochemical parameters at diagnosis. After multivariate , risk factors associated with SSI were: non-administration of preoperative enteral nutrition (odds ratio [OR] = 0.27; 95% confidence interval [CI]: 0.07-1.0), DM (OR = 3.0; 95% CI: 0.9-9.9), the heart disease (OR = 4.6; 95% CI: 1.1-18.6), and laparoscopic surgery (OR = 0.28; 95% CI: 0.08-0.97). The average stay was higher in patients with a diagnosis of SSI (11.9 vs. 9.2 days). CONCLUSIONS: Independent risk factors for SSI in CRC were the non-administration of pre-operative enteral nutrition, the existence of heart disease, and open surgery.
OBJETIVO: Estudiar la incidencia de infección del sitio quirúrgico y evaluar sus factores de riesgo en pacientes intervenidos de cirugía colorrectal electiva. MÉTODO: Se realizó un estudio de cohortes prospectivo desde enero de 2017 hasta diciembre de 2018. RESULTADOS: Se incluyeron 130 pacientes. La incidencia acumulada de infección del sitio quirúrgico fue del 12,3% (n = 16), siendo el 56,25% infecciones de herida y el 31,25% infecciones órgano-espacio. Los factores de riesgo asociados a infección del sitio quirúrgico con significación estadística fueron la no administración de nutrición oral preoperatoria, la diabetes mellitus, la enfermedad cardiaca, la presencia de síntomas en el momento del diagnóstico de cáncer colorrectal y tener al menos dos parámetros bioquímicos nutricionales alterados. Tras el análisis multivariante se asociaron la no administración de nutrición enteral preoperatoria (odds ratio [OR] = 0,27; intervalo de confianza del 95% [IC95%]: 0,07-1,0), la diabetes mellitus (OR = 3,0; IC95%: 0,9-9,9), la enfermedad cardiaca (OR = 4,6; IC95%: 1,1-18,6) y la cirugía laparoscópica (OR = 0,28; IC95%: 0,08-0,97). La estancia media fue mayor en los pacientes con diagnóstico de infección del sitio quirúrgico (11,9 frente a 9,2 días). CONCLUSIONES: Los factores de riesgo independientes para el desarrollo de infección del sitio quirúrgico en los pacientes con cáncer colorrectal fueron la no administración de nutrición oral preoperatoria, la enfermedad cardiaca y la cirugía abierta.

BACKGROUND: Neoadjuvant therapy, followed by surgery, reduces the risk of local relapse in rectal cancer, but approximately 30% will relapse with distant metastases, highlighting the importance of adjuvant chemotherapy (aCT). OBJECTIVE: The objective of the study was to study two regimens of adjuvant treatment in patients with locally advanced rectal cancer and analyze their efficacy and toxicity. METHODS: Between January 2009 and December 2016, 193 patients with Stage II-III rectal cancer who had received neoadjuvant therapy were included by consecutive non-probability sampling. The decision to administer aCT, as well as the specific regimen, was at the discretion of the medical oncologist. Disease-free survival (DFS) and overall survival (OS) were calculated. RESULTS: The mean DFS was 84.85 (95% confidence interval [CI]: 79-90) months in 164 patients receiving aCT, compared to 57.71 (95% CI: 40-74) months in 29 who did not receive aCT (p < 0.001). Then, mean OS was 92.7 (95% CI: 88-97) months and 66.18 (95% CI 51-81) months, respectively (p < 0.001). DFS was 83.6 (95% CI: 76-91) months in 74 patients receiving adjuvant 5-fluorouracil (5-FU), and 82.9 (95% CI: 75-90) months in 90 receiving 5-FU plus oxaliplatin (p = 0.49). OS was 87 (95% CI: 80-94) versus 93.65 (95% CI: 88-99) months, respectively (p = 0.76). The multivariate analysis identified aCT hazard ratio (HR) 0.30 (95% CI: 0.1-0.46), perineural invasion HR 3.36 (95% CI: 1.7-6.5), and pathological complete response HR 0.10 (95% CI; 0.01-0.75) as independent markers of DFS. CONCLUSIONS: In our study, aCT was associated with longer DFS and OS. 5-FU plus oxaliplatin showed greater toxicity with no added benefit in DFS or OS.

OBJECTIVE: To assess compliance of antibiotic prophylaxis in surgery for acute appendicitis in children and its effect on surgical site infection. METHODS: We carried out a prospective cohort study to evaluate compliance of antibiotic prophylaxis in appendectomies in children. An assessment of the level of compliance with prophylaxis was made, as well as the causes of non-compliance. The effect of non-compliance of antibiotic prophylaxis on the incidence of surgical site infection was studied with the adjusted relative risk (RR) with a backstep logistic regression model. RESULTS: The study included a total of 412 patients. Antibiotic prophylaxis was indicated in 348 patients, and administered in 95.7% of cases, with an overall protocol compliance of 90.7%. The principal cause of non-compliance was time of initiation. Cumulative incidence of surgical site infection was 2.7%. No relationship was found between inadequate prophylaxis compliance and infection (RR: 1.01; 95% confidence interval: 0.95-1.11; p = 0.61). CONCLUSIONS: Compliance of antibiotic prophylaxis was high, but could be improved. No relationship was found between prophylaxis compliance and surgical site infection rate.

MÉTODO: Estudio de cohortes prospectivo para evaluar la adecuación al protocolo de la profilaxis antibiótica en apendicectomías en población infantil. Se evaluaron la administración de la profilaxis y las causas de la inadecuación. Se estudió el efecto de la inadecuación en la incidencia de infección del sitio quirúrgico con el riesgo relativo (RR) ajustado con un modelo de regresión logística por pasos hacia atrás. RESULTADOS: Se estudiaron 412 pacientes. La profilaxis antibiótica estaba indicada en 348 pacientes y se administró en el 95.7% de los casos, con una adecuación global al protocolo del 90.7%. La causa principal del incumplimiento fue la hora de inicio. La incidencia acumulada de infección del sitio quirúrgico fue del 2.7%. No se encontró relación entre la adecuación de la profilaxis y la infección del sitio quirúrgico (RR: 1.01; intervalo de confianza del 95%: 0.95-1.11; p = 0.61). CONCLUSIONES: La adecuación de la profilaxis antibiótica fue alta, pero puede mejorarse. No se encontró relación entre la adecuación de la profilaxis antibiótica y la incidencia de infección del sitio quirúrgico.

The medium arcuate ligament syndrome is a rare disorder that results from luminal narrowing of the celiac artery by the insertion of diaphragmatic muscle or the celiac nerve plexus. The syndrome is characterized by weight loss, postprandial abdominal pain, nausea, vomiting and an epigastric murmur. Surgical management involves the complete division of the medial arcuate ligament. We present two cases satisfactorily treated by laparoscopic surgery. The role of minimally invasive surgery in the treatment of this syndrome is a safe alternative approach to open surgery.
El síndrome de ligamento arcuato medio es un trastorno poco frecuente que resulta del estrechamiento luminal de la arteria celíaca por la inserción de fibras musculares diafragmáticas o bandas fibrosas del plexo nervioso celíaco. El síndrome se caracteriza por pérdida de peso, dolor abdominal posprandial, náuseas, vómitos y un soplo epigástrico. El manejo quirúrgico implica la división completa del ligamento arqueado mediano. Presentamos dos casos tratados satisfactoriamente mediante cirugía laparoscópica. El papel de la cirugía mínimamente invasiva en el tratamiento de este síndrome es una vía de abordaje segura alternativa a la cirugía abierta.
