RESUMEN
Resumen Introducción y objetivo: La infección por coronavirus (COVID-19) en pacientes intervenidos es causa de importante mortalidad posoperatoria, aunque su incidencia es variable. El objetivo primario fue evaluar la incidencia de COVID-19 en los pacientes intervenidos en nuestro Servicio de Cirugía General y Digestiva, durante el máximo impacto de la pandemia en España. El objetivo secundario fue evaluar la mortalidad perioperatoria y determinar los factores de riesgo para la infección por COVID-19. Materiales y Método: Estudio observacional retrospectivo de pacientes consecutivos sometidos a Cirugía General y Digestiva con ingreso superior a 24 h, del 1 de febrero de 2020 al 30 de abril de 2020 en un hospital terciario de Madrid, España. Resultados: Se analizaron 441 pacientes: 423 sin COVID-19 y 18 con COVID-19. Las características preoperatorias y operatorias fueron similares para ambos grupos, salvo por el grado ASA (American Society of Anesthesiologists). La incidencia de COVID-19 en los pacientes intervenidos fue del 4,1%. La mortalidad posoperatoria fue elevada, del 22,2% en pacientes con COVID-19, frente a un 2,8% en pacientes no COVID-19 (p: 0,003). Los factores de riesgo para la infección por COVID-19 en los pacientes intervenidos fueron una estancia hospitalaria prolongada (OR: 1,035 [95% CI: 1,007-1,065]) y la reintervención quirúrgica (OR: 5,025 [95% CI: 1,650-15,311]). Conclusión: Las intervenciones durante la pandemia de COVID-19 causaron una baja tasa de infección con elevada mortalidad posoperatoria. La intervención quirúrgica debe valorarse frente al riesgo adicional para el paciente en contextos de alta transmisión.
The impact of coronavirus disease (COVID-19) in intervened patients seems to cause large postoperative mortality, although its incidence varies among centres. Primary aim was to evaluate the incidence of COVID-19 on the patients intervened in our General and Digestive Surgery Department, during the maximum impact of the pandemia in Spain. Secondary outcomes were evaluating perioperative mortality, and determining the risk factors for COVID-19 infection. Materials and Method: Retrospective single centre study of consecutive patients undergoing general and gastrointestinal surgical procedures with more than 24 hours of inhospital stay, from February 1, 2020 to April 30, 2020 in a tertiary referral centre in Madrid, Spain. Results: A total of 441 patients were analysed: 423 were non-COVID-19 patients while 18 of them had COVID-19. Preoperative and operative characteristics were similar for both groups, unless for the American Society of Anesthesiologists grade. The incidence of COVID-19 in our intervened patients was 4.1%. Postoperative mortality was high among surgical patients with COVID-19, with a mortality rate of 22.2% compared to a 2.8% in non COVID-19 patients. The risk factors for COVID-19 infection were a prolonged postoperative stay (OR: 1.035 [95% CI: 1.007-1.065]) and the need of a reintervention (OR: 5.025 [95% CI: 1.650-15.311]). Conclusion: Surgical interventions during the COVID-19 pandemia resulted in a low infection rate but a high postoperative COVID-19 mortality. The decision to intervene must be carefully balanced against the additional risk for patients in a high transmission setting.

OBJETIVO: Las infecciones de sitio quirúrgico se pueden evitar y los programas de control basados en paquetes de medidas preventivas son eficaces para reducir su incidencia. El objetivo de este estudio fue evaluar el efecto de un Plan de Mejora de Calidad y Seguridad Clínica del paciente intervenido de apendicectomía en la incidencia de infección del sitio quirúrgico. MÉTODO: Se realizó un estudio cuasi-experimental con análisis antes y después de la introducción de un Plan de Calidad y Seguridad Clínica. Se incluyeron pacientes intervenidos de apendicectomía. Se estudió la incidencia de infección del sitio quirúrgico durante los 30 días posteriores a la cirugía (periodo máximo de incubación de infección quirúrgica). Se evaluó el efecto de la intervención con la odds ratio (OR) ajustada con un modelo de regresión logística. RESULTADOS: Se incluyeron 606 pacientes, 267 en el periodo 2009-2010 (antes del plan) y 339 durante 2012-2013 (después del plan). La incidencia de infección del sitio quirúrgico descendió después del plan del 6 al 5.6% (OR: 0.72; intervalo de confianza del 95%: 0.33-1.56; p = 0.839). Hubo mayor cumplimiento de la profilaxis antibiótica, de la preparación prequirúrgica y de la adherencia a la higiene de manos tras la introducción de las medidas. CONCLUSIONES: Aunque la reducción de la incidencia de infección del sitio quirúrgico no presentó diferencias estadísticamente significativas tras las medidas adoptadas, se ha conseguido mejorar la administración de la profilaxis antibiótica, la adherencia a la higiene de manos y la preparación prequirúrgica. OBJECTIVE: Surgical site infections can be prevented. Control programs based on care bundle have proven to be effective in reducing its incidence. The objective of this study was to assess the effectiveness of a Plan for Quality Improvement and Clinical Safety in preventing the incidence of surgical site infection in patients undergoing appendectomy. METHOD: A quasi-experimental study was designed for analysis before and after the introduction of a Plan for Quality and Clinical Safety. Patients undergoing appendectomy were included. The incidence of surgical site infection was studied within 30 days from the time of surgery (maximum incubation period of surgical site infection). The effectiveness of the intervention was evaluated using the odds ratio (OR) adjusted with a logistic regression model. RESULTS: A total of 606 patients were included, of which 267 were operated in the period 2009-2010 (before the plan) and 339 in 2012-2013 (after the plan). The incidence of surgical site infection decreased after the plan from 6 to 5.6% (OR: 0.72; 95% confidence interval: 0.33-1.56; p = 0.839). There was greater compliance of antibiotic prophylaxis, preoperative preparation and adherence to hand hygiene after the introduction of the measures. CONCLUSIONS: Although the reduction in the incidence of surgical site infection after the measures adopted did not show statistical significant differences, important progress has been made in the compliance of antibiotic prophylaxis, adherence to hand hygiene and in the preoperative preparation.

BACKGROUND: There are many factors that can influence surgical site infections (SSI) in cholecystectomies. Incidence of cholecystectomy SSI was studied and compared with the incidence in Madrid Region, Spain, and the United States. METHODS: A prospective cohort study was conducted which included all patients who underwent gallbladder surgery for 5 consecutive years, at the Alcorcón Foundation University Teaching Hospital. SSI incidence rate was calculated. An association between risk factors and SSI incidence was assessed with the relative risk (RR). Infection rates were compared to those in the Madrid Region and to the overall Spanish and United States rates using the standardized infection ratio (SIR). RESULTS: The study included 1532 patients. Cumulative overall SSI was 1.96% (95% confidence interval [CI]: 1.3-2.7). The SIR was 0.89 with respect to the Madrid Region, 0.77 with respect to Spain's rate, and 1.77 with respect to the United States' rate. A laparoscopic route protected against infection (RR = 0.43; 95% CI: 0.2-0.9). Razor shaving in surgical preparation, duration of surgery, and neoplasm increased SSI incidence. CONCLUSIONS: SSI incidence rates among cholecystectomized patients at our hospital are higher than rates in the United States. A laparoscopic route protected against SSI.

INTRODUCTION: Total mesorectal excision (TME) of the rectum has been advocated as the gold standard surgical treatment of middle and lower third rectal cancer. Laparoscopy has gained acceptance among surgeons in the treatment of colon malignancies, while scepticism exists about laparoscopic TME in terms of safety and its oncological adequacy. OBJECTIVE: To evaluate the impact of laparoscopic TME on surgical and oncological outcome in a group of consecutive unselected patients. METHODS: One hundred and thirty-two patients with middle or inferior rectal cancer were admitted to our unit and underwent TME from December 1998 to February 2008. Eighty-nine patients were approached with laparoscopy. Patients staged cT3/4 cTxN+ or uTxN+ were submitted to neoadjuvant treatment. Postoperative complications and oncological outcomes were registered. RESULTS: In the laparoscopic group 80 anterior resections (including 4 intersphincteric resections and manual colo- anal anastomosis) and 9 abdominal-perineal resections were performed. 33.3% of patients were enrolled in "long-course" neoadjuvant chemo-radiotherapy (partial and complete response rates 88.2% and 11.8%, respectively). Protective lateral ileostomy was performed in 72% of patients. Mean operative time was 254.3+/-38.3 min and mean blood loss was 215+/-180 ml. Conversion rate was 12.7%. Morbidity rate was 39.3% without mortality. The rate of anastomotic leaks was 13.48%, reoperation rate 13.48%, recovery rate 3.1+/-1.4 days and hospital stay 10.4+/-4.6 days. Concerning adequacy of oncologic resection, mean distance of the tumour from the anal verge was 4.3+/-2.2 cm. Nodal sampling of 12.4+/-4.8 were obtained. Six patients (6/89, 6.74%) had a R1 margin: 3 distal and 3 circumferential. Median follow-up was 29 months and local recurrence rate was 5.79%. Four-year cumulative overall survival was 78% and disease-free survival was 63% (Kaplan-Meier method). CONCLUSIONS: Laparoscopic approach for rectal tumour is a technically demanding procedure, but it is oncologically safe.

Colorectal cancer is one of the best studied of all malignant diseases in terms of genetics and/or molecular prognostic factors. These factors, and relationships with prognosis, may have important implications especially in the design of surgical and adjuvant chemo-radiotherapy options. However, the true prognostic significance of all known factors has yet to be realised. We have reviewed the literature with specific focus on the role of molecular markers involved in prognosis and the prediction of response to adjuvant treatment.

Se recopilaron 26 casos de traumas pancreáticos entre dos hospitales del área metropolitana en un lapso de 5 años y de un año respectivamente. La totalidad de las lesiones fue en personas jóvenes y el agente vulnerante fue principalmente proyectiles por arma de fuego, que producen lesiones múltiples, y la herida pancreática es casi siempre de menor grado (grado I y II). La mortalidad es alta, de 19 por ciento debido a las lesiones asociadas, de 3 o más órganos, y todos los que fallecieron fueron por armas de fuego. No hubo mortalidad en traumas cerrados o por arma blanca. Las complicaciones se presentaron con frecuencia, un 45 por ciento. La envergadura de la cirugía dependió de la intensidad del trauma y de la lesión o no del conducto principal. Predominaron las rafias y drenajes con un 73 por ciento de los casos. Luego la pancreatectomía distal con 19,2 por ciento y 2 casos de procedimientos de Whipple, con una muerte y una sobrevida

A problem which is impeding tuberculosis control in the Health Unit at Magdalena, Peru, as it does in any health service, is lack of regularity in attendance for treatment on the part of ambulatory patients, a large percentage of whom abandon their treatment. In 1967, the bronchopulmonary service in this health unit had several hundred patients; 90 per cent of these followed the course of treatment regularly. The other 10 per cent were recalcitrant.
