Incidencia de la infección de la herida quirúrgica en cirugía colorrectal electiva y su relación con factores perioperatorios

IntroductionSurgical wound infection in colorectal surgery has incidence rate of up to 26%. Peri-operative factors and those of the patients themselves play a part in these infections. The correct administration of the antibiotic, a normal temperature, and hyperoxygenation are a commonly applied triad. The primary aim of the study was to evaluate the incidence of surgical wound infection in patients subjective to colorectal surgery where a surgical infection prevention protocol was applied. The second objective was the relationship between surgical infection and peri-operative factors.Material and methodsAn observational study was conducted on 100 patients who had undergone elective colorectal surgery. Demographic data and related surgical and post-surgical data were recorded. A surgical wound infection was defined using the criteria of Disease Control and Prevention Hospital Infection CentresResultsThe median age of the patients was 68 years (range 25-88), 65% were male, and 59% were ASA 3-4. There was more than 80% compliance to the protocol in its different sections. There was laparoscopic access in 31% of the cases. The incidence of superficial and deep surgical wound infection was 25%. The patients with an infection had a higher prevalence of diabetes (48% vs 24%), transfusion (56% vs 28%), paralytic ileum (48% vs 18.7%), and intra-abdominal abscess (16% vs 3%). The multivariate analysis associated, preoperative haemoglobin and blood glucose, and the duration of the surgery, with incisional infection.ConclusionsThe prevention protocol did not have an impact on the incidence of surgical wound infection.     

Medidas de prevención de la infección de localización quirúrgica en cirugía general. Documento de posicionamiento de la Sección de Infección Quirúrgica de la Asociación Española de Cirujanos

Surgical site infection is associated with prolonged hospital stay and increased morbidity, mortality and healthcare costs, as well as a poorer patient quality of life. Many hospitals have adopted scientifically-validated guidelines for the prevention of surgical site infection. Most of these protocols have resulted in improved postoperative results. The Surgical Infection Division of the Spanish Association of Surgery conducted a critical review of the scientific evidence and the most recent international guidelines in order to select measures with the highest degree of evidence to be applied in Spanish surgical services. The best measures are: no removal or clipping of hair from the surgical field, skin decontamination with alcohol solutions, adequate systemic antibiotic prophylaxis (administration within 30-60 minutes before the incision in a single preoperative dose; intraoperative re-dosing when indicated), maintenance of normothermia and perioperative maintenance of glucose levels.     

Programa de Reducción de la Infección Quirúrgica del Observatorio de Infección en Cirugía (PRIQ-O). Documento de priorización y consenso Delphi de recomendaciones para la prevención de la infección de localización quirúrgica

Surgical site infection is the most frequent and avoidable complication of surgery, but clinical guidelines for its prevention are insufficiently followed. We present the results of a Delphi consensus carried out by a panel of experts from 17 Scientific Societies with a critical review of the scientific evidence and international guidelines, to select the measures with the highest degree of evidence and facilitate their implementation. Forty measures were reviewed and 53 recommendations were issued. Ten main measures were prioritized for inclusion in prevention bundles: preoperative shower; correct surgical hand hygiene; no hair removal from the surgical field or removal with electric razors; adequate systemic antibiotic prophylaxis; use of minimally invasive approaches; skin decontamination with alcoholic solutions; maintenance of normothermia; plastic wound protectors-retractors; intraoperative glove change; and change of surgical and auxiliary material before wound closure.     

Papel de la terapia presión negativa en la prevención de infección del sitio quirúrgico en cirugía colorrectal

BackgroundSurgical site infection (SSI) is one of the most frequent complications in colorectal surgery. It is diagnosed in 10 - 20% of colorectal procedures. Negative Pressure Wound Therapy (NPWT) has shown efficacy in the treatment of chronic and traumatic wounds, wound dehiscence, flaps and grafts. The main objective of this study is to assess NPWT in the prevention of SSI in colorectal surgery. Hospital stay reduction and SSI risk factors are secondary objectives.MethodsWe present a prospective case-control study including 80 patients after a colorectal diagnosis and surgical procedure (elective and non-elective) in 2017. Forty patients were treated with prevention NPWT for one week. Forty patients were treated according to the standard postoperative surgical wound care protocol.ResultsNo significant differences were found in demographic variables, comorbidities, surgical approach, elective or non-elective surgery, mechanical bowel preparation and surgical procedure. Three patients has SSI in the NPWT group (8%) (95%CI 0 – 17.5). Ten patients presented SSI in the control group (25%) (95%CI 12.5 – 37.5) (p = 0.034); OR 0.7 (95%CI 0.006-0.964). Hospital stay in the NPWT group was 8 days versus 12 days in the non-NPWT group (p = 0.22). In the multivariate analysis, mechanical bowel preparation was found to be the only risk factor for SSI (p = 0.047; OR: 0.8, CI 0.45-0.93).ConclusionsNPWT is a useful SSI prevention treatment in colorectal surgery.     

Controversias en la anatomía quirúrgica prostática. Revisión de la literarura

IntroductionRadical prostatectomy technique has improved in the last years based on accumulated surgical experience and new anatomical findings. We think it is time to update anatomical concepts to standardized the criteria for mentioning structures related with radical prostatectomyMaterial and MethodWith the followings key words: “cavernosal nerves, prostatectomy, anatomy, neurovascular bundle” we search in Medline/PubMed database selecting papers fulfilling the search criteria.ConclusionsThe prostate does not have a true capsule but rather an incomplete fibromuscular band as an intrinsic part of the gland. Periprostatic fascia seems to be a different structure from this fibromuscular band. Histologically Denonvilliers´s fascia is formed by two thin layers that cannot be separated during surgery. The longitudinal smooth muscle fibres located beneath the posterior bladder neck corresponds to the posterior longitudinal fascia of the detrusor muscle. Cavernosal nerves are located between the two layers of the endopelvic fascia, the inner layer could be named periprostatic fascia and the outer, levator ani fascia. Cavernosal nerves merged from the pelvic plexus running within a neurovascular bundle around the prostate that could be found as a singular bundle or spread all around the anterolateral surface of this gland. There are overlapping terms to designate the pelvic fascia, therefore it could be useful for Urologists to standardized them.     

Actividad física y fragilidad como indicadores de reserva cardiorrespiratoria y predictores del pronóstico quirúrgico: caracterización de la población quirúrgica en cirugía general y digestiva

Introduction

Frailty and low physical activity and cardiorespiratory reserve are related to higher perioperative morbimortality. The crucial step in improving the prognosis is to implement specific measures to optimize these aspects. It is critical to know the magnitude of the problem in order to implement preoperative optimization programmes.

Preparación mecánica y profilaxis antibiótica por vía oral en cirugía colorrectal. Análisis de la evidencia científica y revisión narrativa

The role of oral antibiotic prophylaxis and mechanical bowel preparation in colorectal surgery remains controversial. The lack of efficacy of mechanical preparation to improve infection rates, its adverse effects, and multimodal rehabilitation programs have led to a decline in its use. This review aims to evaluate current evidence on antegrade colonic cleansing combined with oral antibiotics for the prevention of surgical site infections. In experimental studies, oral antibiotics decrease the bacterial inoculum, both in the bowel lumen and surgical field. Clinical studies have shown a reduction in infection rates when oral antibiotic prophylaxis is combined with mechanical preparation. Oral antibiotics alone seem to be effective in reducing infection in observational studies, but their effect is inferior to the combined preparation. In conclusion, the combination of oral antibiotics and mechanical preparation should be considered the gold standard for the prophylaxis of postoperative infections in colorectal surgery.     

Hiperlactatemia en la ablación quirúrgica de la fibrilación auricular y cirugía cardiaca. ¿Es un factor predictivo de morbimortalidad posoperatoria?

IntroductionIncreased serum lactate in postoperative cardiac surgery is very common and its pathogenesis is due to multiple factors. The elevation of serum lactate is associated with tissue hypoxia (hyperlactatemia type A) and non-hypoxic (hyperlactatemia type B) metabolic disorders. The aim of the study was to assess the evolution of postoperative lactate in surgical atrial fibrillation ablation during cardiac surgery, and to determine whether lactate levels could be predictors of morbimortality.Material and methodsA case-control study was conducted on 32 patients undergoing surgical atrial fibrillation ablation and cardiac surgery (Maze group) and 32 matched patients (Control group), operated on between 2011 and 2012. An analysis was made of the levels of postoperative lactate, perioperative morbimortality and hospital length of stay. A univariate and multivariate study was performed for a composite endpoint of morbimortality, and prolonged length of stay.ResultsLactate levels were significantly higher at 6, 12 and 24 h in the Maze group. The univariate analysis showed that being in the Maze group (OR 3.88; 95% CI 1.3-11.1; P = .01) and an elevated lactate at 12 h (OR 1.33; 95% CI 1.01-1.7; P = .04) were significant predictors of major complications, mortality, and longer hospital stays. In the multivariate analysis, surgical atrial fibrillation ablation (Maze group) was an independent predictor of major complications (OR 4.13; 95% CI 1.312.9; P = .015) for the morbimortality composite endpoint (OR 3.9; 95% CI 1.3-11.6; P = .01), and prolonged length of stay in the Intensive Care Unit (OR 5.7; 95% CI 2.01-15.7; P = .01).ConclusionsThe atrial fibrillation surgical ablation may be a not-yet-described cause of type B hyperlactatemia, with serum peak values being reached between 4-24 h after cardiac surgery. The predictive value of this elevation, its correlation with morbimortality, its sensitivity and specificity to discriminate the significant thresholds needs to be defined.     

Infección del sitio quirúrgico en cirugía hepatobiliopancreática y su relación con la concentración sérica de vitamina D

IntroductionWhile several studies have examined the correlation between vitamin D concentrations and post-surgical nosocomial infections, this relationship has yet to be characterized in hepatobiliary surgery patients. We investigated the relationship between serum vitamin D concentration and the incidence of surgical site infection (SSI) in patients in our hepatobiliary surgery unit.MethodsParticipants in this observational study were 321 successive patients who underwent the following types of interventions in the hepatobiliary surgery unit of our center over a 1-year period: cholecystectomy, pancreaticoduodenectomy, total pancreatectomy, segmentectomy, hepatectomy, hepaticojejunostomy and exploratory laparotomy. Serum vitamin D levels were measured upon admission and patients were followed up for 1 month. Mean group values were compared using a Student's T-test or Chi-squared test. Statistical analyses were performed using the Student's T-test, the Chi-squared test, or logistic regression models.ResultsSerum concentrations >33.5 nmol/l reduced the risk of SSI by 50%. Out of the 321 patients analyzed, 25.8% developed SSI, mainly due to organ-cavity infections (incidence, 24.3%). Serum concentrations of over 33.5 nmol/l reduced the risk of SSI by 50%.ConclusionsHigh serum levels of vitamin D are a protective factor against SSI (OR, 0.99). Our results suggest a direct relationship between serum vitamin D concentrations and SSI, underscoring the need for prospective studies to assess the potential benefits of vitamin D in SSI prevention.

Guía anestésico-quirúrgica en el tratamiento de la cirugía de aorta ascendente y del arco aórtico. Documento de consenso de la Sociedad Española de Cirugía Cardiovascular y Endovascular y la Sociedad Española de Anestesiología,Reanimación y Terapeútica del Dolor

Aortic pathology is always a challenge for the clinician, and must be diagnosed and treated by a multidisciplinary team due to the technical and technological complexity of the resources used. Ongoing efforts to implement a systematic, protocolized approach involving “Aortic teams” made up of cardiologists, cardiac surgeons, vascular surgeons, anaesthesiologists and radiologists, among others are now leading to improved outcomes. The aim of this consensus document drawn up by the Aortic working groups of the Spanish Society of Anaesthesiology, Resuscitation and Pain Therapy (SEDAR) and the Spanish Society of Thoracic and Cardiovascular Surgery (SECTCV) is to disseminate a set of working protocols. The latest consensus document of the European Association for Cardio-Thoracic Surgery (EACTS) and the European Society for Vascular Surgery (ESVS) define the concept of “AORTIC TEAM”(1). The aortic team should be closely involved from diagnosis to treatment and finally follow-up, and should be formed of cardiac and vascular surgeons working together with anaesthesiologists, cardiologists, radiologists and geneticists. Treatment of aortic pathologies should be centralised in large centres, because this is the only way to effectively understand the natural course of the disease, provide the entire range of treatment options under one umbrella and treat potential complications. A streamlined emergent care pathway (24/7 availability), adequate transportation and transfer capabilities, as well as rapid activation of the multidisciplinary team must be available. In light of the complexity and constant evolution of therapeutic options, we present this first version of the Anaesthesiology and surgical guidelines for surgery of the ascending aorta and aortic arch. Some questions will no doubt remain unanswered, and future versions will include new techniques that, though implemented in some centres, are still not widely recommended.     

El impacto de la cirugía robótica en Urología

IntroductionMore than a decade ago, robotic surgery was introduced into urology. Since then, the urological community started to look at surgery from a different angle. The present, the future hopes, and the way we looked at our past experience have all changed.MethodsBetween 2000 and 2011, the published literature was reviewed using the National Library of Medicine database and the following key words: robotic surgery, robot-assisted, and radical prostatectomy. Special emphasis was given to the impact of the robotic surgery in urology. We analyzed the most representative series (finished learning curve) in each one of the robotic approaches regarding perioperative morbidity and oncological outcomes.ResultsThis article looks into the impact of robotics in urology, starting from its background applications before urology, the way it was introduced into urology, its first steps, current status, and future expectations. By narrating this journey, we tried to highlight important modifications that helped robotic surgery make its way to its position today. We looked as well into the dramatic changes that robotic surgery introduced to the field of surgical training and its consequence on its learning curve.ConclusionBasic surgical principles still apply in Robotics: experience counts, and prolonged practice provides knowledge and skills. In this way, the potential advantages delivered by technology will be better exploited, and this will be reflected in better outcomes for patients.     

Evolución del abordaje quirúrgico de la colecistitis aguda en una unidad de cirugía de urgencias

ObjectiveThe application of the laparoscopic technique in acute cholecystitis is still subject to controversy. The aim of this study is to asses the applicability, safety, benefits and complications of the laparoscopic approach in patients with acute cholecystitis, as well as the development of this technique in the emergency surgery department of a tertiary hospital, compared to laparotomy.Material and methodThe study consisted of 354 patients with acute cholecystitis syndromes operated either by open or laparoscopic surgery, during the years 2006 to 2009.ResultsThe laparoscopic method was used in 253 patients, and 101 by the open route, with the slight majority being male (57.67%) and with a mean age of 62.83 years.The number of laparoscopic cholecystectomies increased from 60% in 2006, to 79% in 2009. The mean hospital stay (including those with and without complications) was shorter using the laparoscopic approach, compared to open surgery (showing a difference of approximately 6 days). The postoperative complications in laparoscopy during the four years studied decreased from 21.42 to 11.3%. The local and general complications were significantly associated with time since the start of the acute symptoms and the surgery, as well as the histopathological state of the gall bladder.ConclusionsThe laparoscopic approach continues to play an increasing role in the treatment of this disease, becoming the main surgical option in our hospital.
