RESUMO
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.

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.
