RESUMO
PURPOSE: Although mortality and morbidity of severe acute calculous cholecystitis (ACC) are still a matter of concern, the impact of inadequate empirical antibiotic therapy has been poorly studied as a risk factor. The objective was to assess the impact of the adequacy of empirical antibiotic therapy on complication and mortality rates in ACC. METHODS: This observational retrospective cohort chart-based single-center study was conducted between 2012 and 2016. A total of 963 consecutive patients were included, and pure ACC was selected. General, clinical, postoperative, and microbiological variables were collected, and risk factors and consequences of inadequate treatment were analyzed. RESULTS: Bile, blood, and/or exudate cultures were obtained in 76.3% of patients, more often in old, male, and severely ill patients (P < 0.001). Patients who were cultured had a higher overall rate of postoperative complications (47.4% vs. 29.7%; P < 0.001), as well as of severe complications (11.6% vs. 4.7%; P = 0.008). Patients with positive cultures had more overall complications (54.8% vs. 39.6%; P = 0.001), more severe complications (16.3% vs. 6.7%; P = 0.001), and higher mortality rates (6% vs. 1.9%; P = 0.012). Patients who received inadequate empirical antibiotic therapy had a fourfold higher mortality rate than those receiving adequate therapy (n = 283; 12.8% vs. 3.4%; P = 0.003). This association was especially marked in severe ACC TG-III patients (n = 132; 18.2 vs. 5.1%; P = 0.018) and remained a predictor of mortality in a binary logistic regression (OR 4.4; 95% CI 1.3-15.3). CONCLUSION: Patients with positive cultures developed more complications and faced higher mortality. Adequate empirical antibiotic therapy appears to be of paramount importance in ACC, particularly in severely ill patients.

BACKGROUND: Postoperative adhesions represent 75% of all acute small bowel obstructions. Although open surgery is considered the standard approach for adhesiolysis, laparoscopic approach is gaining popularity. METHODS: A retrospective study with data from a prospectively maintained data base of all patients undergoing surgical treatment for adhesive small bowel obstruction (ASBO) from January 2007 to May 2016 was conducted. Postoperative outcomes comparing open vs laparoscopic approaches were analysed. An intention to treat analysis was performed. The aim of the study was to evaluate the potential benefits of the laparoscopic approach in the treatment of ASBO. RESULTS: 262 patients undergoing surgery for ASBO were included. 184 (70%) and 78 (30%) patients were operated by open and laparoscopic approach respectively. The conversion rate was 38.5%. Patients in the laparoscopic group were younger (p < 0.001), had fewer previous abdominal operations (p = 0.001), lower ASA grade (p < 0.001), and less complex adhesions were found (p = 0.001). Operative time was longer in the open group (p = 0.004). Laparoscopic adhesiolysis was associated with a lower overall complication rate (43% vs 67.9%, p < 0.001), lower mortality (p = 0.026), earlier oral intake (p < 0.001) and shorter hospital stay (p < 0.001). Specific analysis of patients with single band and/or internal hernia who did not need bowel resection, also demonstrated fewer complications, earlier oral intake and shorter length of stay. In the multivariate analysis, the open approach was an independent risk factor for overall complications compared to the laparoscopic approach (Odds Ratio = 2.89; 95% CI 1.1-7.6; p = 0.033). CONCLUSIONS: Laparoscopic management of ASBO is feasible, effective and safe. The laparoscopic approach improves postoperative outcomes and functional recovery, and should be considered in patients in whom simple band adhesions are suspected. Patient selection is the strongest key factor for having success.

INTRODUCTION: The current treatment for acute calculous cholecystitis (ACC) is early laparoscopic cholecystectomy, in association with appropriate empiric antibiotic therapy. In our country, the evolution of the prevalence of the germs involved and their resistance patterns have been scarcely described. The aim of the study was to analyze the bacterial etiology and the antibiotic resistance patterns in ACC. METHODS: We conducted a single-center, retrospective, observational study of consecutive patients diagnosed with ACC between 01/2012 and 09/2019. Patients with a concomitant diagnosis of pancreatitis, cholangitis, postoperative cholecystitis, histology of chronic cholecystitis or carcinoma were excluded. Demographic, clinical, therapeutic and microbiological variables were collected, including preoperative blood cultures, bile and peritoneal fluid cultures. RESULTS: A total of 1104 ACC were identified, and samples were taken from 830 patients: bile in 89%, peritoneal fluid and/or blood cultures in 25%. Half of the bile cultures and less than one-third of the blood and/or peritoneum samples were positive. Escherichia coli (36%), Enterococcus spp (25%), Klebsiella spp (21%), Streptococcus spp (17%), Enterobacter spp (14%) and Citrobacter spp (7%) were isolated. Anaerobes were identified in 7% of patients and Candida spp in 1%. Nearly 37% of patients received inadequate empirical antibiotic therapy. Resistance patterns were scrutinized for each bacterial species. The main causes of inappropriateness were extended-spectrum beta-lactamase-producing bacteria (34%) and Enterococcus spp (45%), especially in patients older than 80 years. CONCLUSIONS: Updated knowledge of microbiology and resistance patterns in our setting is essential to readjust empirical antibiotic therapy and ACC treatment protocols.

INTRODUCTION: Observation is the gold standard for stable patients with stab wounds. The aim of the study was to analyse the value of the primary review and complementary examinations to predict the need for surgery in stab wound patients in order to decrease observation times. METHODS: A retrospective study of stab wound patients recorded in a database. Clinical and diagnostic workup parameters were analysed. The main variable was the need for surgery. RESULTS: A total of 198 patients were included between 2006 and 2009, with a mean injury severity score (ISS) of 7.8±7, and 0.5% mortality. More than half (52%) of the patients suffered multiple wounds. Wound distribution was 23% neck, 46% thorax and 31% abdomen. Surgery was required in 73 (37%) patients (59% immediate, 27% delayed and 14% delayed). The need for surgery was associated with a lower revised trauma score (RTS), evisceration, active bleeding, and fascial penetration. Initial and control haemoglobin levels were significantly lower in patients who required surgery. A positive computerised tomography (CT) scan was associated with surgery. There were complications in 18% of patients, and they were more frequent in those who underwent surgery. There was no difference in complication rates between immediate and delayed (P=.72). Surgery was finally required in 10% of the patients with no abnormalities in the primary review and diagnostic workup, and 6% of those developed complications. CONCLUSION: None of the parameters studied could individually assess the need for surgery. Primary and secondary reviews were the most important diagnostic tool, but CT scan should be used more often. An observation period of 24 hours is recommended in torso penetrating wounds.

OBJECTIVE: To challenge the risk factors described in Tokyo Guidelines in Acute Calculous Cholecystitis. METHODS: Retrospective single center cohort study with 963 patients with Acute Cholecystitis during a period of 5 years. Some 725 patients with a "pure" Acute Calculous Cholecystitis were selected. The analysis included 166 variables encompassing all risk factors described in Tokyo Guidelines. The Propensity Score Matching method selected two subgroups of patients with equal comorbidities, to compare the severe complications rate according to the initial treatment (Surgical vs Non-Surgical). We analyzed the Failure-to-rescue as a quality indicator in the treatment of Acute Calculous Cholecystitis. RESULTS: the median age was 69 years (IQR 53-80). 85.1% of the patients were ASA II or III. The grade of the Acute Calculous Cholecystitis was mild in a 21%, moderate in 39% and severe in 40% of the patients. Cholecystectomy was performed in 95% of the patients. The overall complications rate was 43% and the mortality was 3.6%. The Logistic Regression model isolated 3 risk factor for severe complication: ASA > II, cancer without metastases and moderate to severe renal disease. The Failure-to-Rescue (8%) was higher in patients with non-surgical treatment (32% vs. 7%; P = 0.002). After Propensity Score Matching, the number of severe complications was similar between Surgical and Non-Surgical treatment groups (48.5% vs 62.5%; P = 0.21). CONCLUSIONS: the recommended treatment for Acute Calculous Cholecystitis is the Laparoscopic Cholecystectomy. Only three risk factors from the Tokyo Guidelines list appeared as independent predictors of severe complications. The failure-to-rescue is higher in non-surgically treated patients.

A non-systematic review of the published scientific evidence has been carried out on the duration of empirical antibiotic treatment in surgical intra-abdominal infections (IIA) with effective focus control. Given the progressive increase in antibiotic resistance, it is urgent to have strategies to reduce the pressure on the microbiota. The American guidelines made by Mazuski et al. of 20171, as the central axis in the recommendations of the duration of empirical antibiotic treatment in intra-abdominal infections with control of the focus and a bibliographic search of all the articles that contained the keywords in Pubmed and Google Scholar is added. 21 articles referring to the duration of empirical antibiotic treatment in intra-abdominal infection with control of the focus are collected. With the American guidelines and these articles, a proposal is prepared for the duration of empirical antibiotic treatment in patients without risk factors between 24 and 72 h. And in those who present risk factors, it should be individualized with active monitoring every 24 h of fever, paralytic ileus and leukocytosis (FIL), before an early detection of complications or the need for changes in antibiotic treatment. Short treatments are just as effective as those of longer durations and are associated with fewer adverse effects, therefore, daily adjusting and reassessing the duration of empirical antibiotic treatment is essential for better practice.

OBJECTIVES: Antibiotic allergy labels (AAL) are related to worse therapeutic results. Strategies to improve the management of these patients, such as the implementation of antibiotic desensitization, are essential for Antimicrobial Stewardship Programs (ASP). The aim of our study is to evaluate the efficacy and safety of antibiotic desensitization procedures for the management of patients with AAL. METHODS: A retrospective study from 2015 to 2022 was performed to describe all antibiotic desensitization conducted in our institution, within the framework of ASP. A systematic literature review using electronic databases, such as PubMed, was also done to identify studies describing antibiotic desensitization between 2000 and 2022. RESULTS: Sixteen antibiotic desensitization protocols were carried out in our institution. In fourteen cases, the desensitization was successfully completed, and the antibiotic could be used to treat the infection. In the systematic review, twenty-two studies were included, with a total of 202 desensitization episodes . In 97% of them, the desensitization was completed successfully. No desensitization-related mortality was observed neither in our cohort nor in literature review. CONCLUSIONS: Antibiotic desensitization strategies should be considered a safe and effective tool that can be included in ASP for patients with a high risk of or confirmed allergy to penicillin.

BACKGROUND: Acute calculous cholecystitis (ACC) is the second most frequent surgical condition in emergency departments. The recommended treatment is the early laparoscopic cholecystectomy; however, the Tokyo Guidelines (TG) advocate for different initial treatments in some subgroups of patients without a strong evidence that all patients will benefit from them. There is no clear consensus in the literature about who is the unfit patient for surgical treatment. The primary aim of the study is to identify the risk factors for mortality in ACC and compare them with Tokyo Guidelines (TG) classification. METHODS: Retrospective unicentric cohort study of patients emergently admitted with and ACC during 1 January 2011 to 31 December 2016. The study comprised 963 patients. Primary outcome was the mortality after the diagnosis. A propensity score method was used to avoid confounding factors comparing surgical treatment and non-surgical treatment. RESULTS: The overall mortality was 3.6%. Mortality was associated with older age (68 + IQR 27 vs. 83 + IQR 5.5; P = 0.001) and higher Charlson Comorbidity Index (3.5 + 5.3 vs. 0+2; P = 0.001). A logistic regression model isolated four mortality risk factors (ACME): chronic obstructive pulmonary disease (OR 4.66 95% CI 1.7-12.8 P = 0.001), dementia (OR 4.12; 95% CI 1.34-12.7, P = 0.001), age > 80 years (OR 1.12: 95% CI 1.02-1.21, P = 0.001) and the need of preoperative vasoactive amines (OR 9.9: 95% CI 3.5-28.3, P = 0.001) which predicted the mortality in a 92% of the patients. The receiver operating characteristic curve yielded an area of 88% significantly higher that 68% (P = 0.003) from the TG classification. When comparing subgroups selected using propensity score matching with the same morbidity and severity of ACC, mortality was higher in the non-surgical treatment group. (26.2% vs. 10.5%). CONCLUSIONS: Mortality was higher in ACC patients treated with non-surgical treatment. ACME identifies high-risk patients. The validation to ACME with a prospective multicenter study population could allow us to create a new alternative guideline to TG for treating ACC. TRIAL REGISTRATION: Retrospectively registered and recorded in Clinical Trials. NCT04744441.

El aumento progresivo de las resistencias antibióticas apremia el tener estrategias para disminuir la presión sobre la microbiota. La duración del tratamiento antibiótico empírico es variable, a pesar de las recomendaciones de las guías. Se ha realizado una revisión bibliográfica de la evidencia científica publicada sobre la duración del tratamiento antibiótico empírico en las infecciones intraabdominales quirúrgicas con control de foco efectivo. Se analizan las guías americanas realizadas por Mazuski et al. de 2017 como eje central en las recomendaciones de la duración de tratamiento antibiótico empírico en infecciones intraabdominales con control del foco y se añade una búsqueda bibliográfica de todos los artículos que contuviesen las palabras claves en Pubmed y Google Scholar. Se recopilan 21 artículos referentes en la duración del tratamiento antibiótico empírico en la infección intraabdominal con control del foco. Con las guías americanas y estos artículos se ha elaborado una propuesta de duración del tratamiento antibiótico empírico en pacientes sin factores de riesgo entre 24 y 72 h. Y en los que presentan factores de riesgo se habría de individualizar el mismo con monitorización activa cada 24 h de fiebre, íleo paralítico y leucocitosis, ante una detección precoz de complicaciones o de necesidad de cambios en el espectro antibiótico. Los tratamientos cortos son igual de eficaces que los de duraciones más prolongadas y se asocian a menos tasa de efectos adversos, por tanto, ajustar y revaluar diariamente la duración del tratamiento antibiótico empírico es fundamental para una mejor praxis (AU)

BACKGROUND: In patients with intra-abdominal infection, inappropriate initial empiric antibiotic therapy is associated with greater morbidity. We evaluated the impact of adequate empiric antibiotic treatment together with control of the infection focus on the morbidity and mortality rates of patients with secondary peritonitis. METHODS: This was a prospective, observational study with the participation of 24 Spanish hospitals and 362 patients with secondary peritonitis (262 community-acquired, 100 post-operative). Therapeutic failure (infectious complications or death) was classified into four categories according to whether empiric antibiotic treatment was appropriate and the infection focus was controlled. RESULTS: The rates of therapeutic failure, re-operation, and mortality were 48%, 13%, and 8%, respectively. Empiric antibiotic treatment was inappropriate in 39% of cases, which was associated with a higher rate of surgical site infection (53% vs. 40%; p=0.031) and death (12% vs. 5%; p=0.021) than was observed in patients receiving appropriate initial empiric therapy. Eight percent of patients in whom control of the infection focus was not obtained suffered from more infectious complications (76% vs. 52%; p=0.01) and surgical site infections (69% vs. 44%; p=0.01); and in this group, both therapeutic failure and mortality rates were similar, independent of whether the empiric antibiotic therapy was appropriate. CONCLUSION: Inappropriate initial empiric antibiotic therapy was associated with higher rates of therapeutic failure, surgical site infection, re-operation, and death. Classification of therapeutic failure into four categories according to the appropriateness of empiric antibiotic therapy and the success of infection control provided excellent discrimination of morbidity and death.

Introducción: Analizar los factores de riesgo de complicaciones para colecistitis aguda litiásica confrontándolos a las Tokyo Guidelines. Métodos: Estudio retrospectivo de 963 pacientes con colecistitis aguda durante 5 años. Se seleccionaron 725 pacientes con colecistitis aguda litiásica «pura», y analizaron 166 variables mediante regresión logística, incluyendo todos los factores de riesgo de las Tokyo Guidelines. Mediante el Propensity Score Matching, se seleccionaron subpoblaciones comparables de 75 pacientes y se analizaron las complicaciones según el tratamiento realizado (quirúrgico/no quirúrgico) y se utilizó el fallo en el rescate como indicador de calidad del tratamiento en la colecistitis aguda litiásica. Resultados: La mediana de edad fue de 69 años (RIQ 53-80). La mayoría de los pacientes fueron ASA II o III (85,1%). El 21% de las colecistitis fueron leves, el 39% moderadas y el 40% graves. Se colecistectomizó al 95% de los pacientes. El 43% de los pacientes se complicaron y la mortalidad fue del 3,6%. Los factores de riesgo independientes para complicaciones graves fueron ASA>II, tumor sólido sin metástasis e insuficiencia renal. El fallo en el rescate (8%) fue mayor en los no operados (32% vs. 7%; P=0,002). Tras realizar el Propensity Score Matching, la tasa de complicaciones graves fueron comparables entre operados y no operados (48,5% vs. 62,5%; P=0,21). Conclusiones: La colecistectomía precoz es el tratamiento preferente para la colecistitis aguda litiásica. Solo tres de los factores de las Tokyo Guidelines son variables independientes para predecir complicaciones graves. El fallo en el rescate es mayor en los pacientes no intervenidos quirúrgicamente.

INTRODUCTION: Anal intraepithelial neoplasia is a precursor condition of squamous anal carcinoma. The groups at risk of this lesion are patients with anogenital condylomata, cervical dysplasia, human immunodeficiency virus infection and, in general, patients with HPV infection. The aim of this study was to analyse the results of a diagnostics protocol of Anal Intraepithelial Neoplasia in high risk population using anal cytology. PATIENTS AND METHOD: The protocol is based on a visit in the outpatient department, clinical interview, physical examination and anal cytology evaluated by Bethesda criteria. The cross-sectional observational study was designed to study the anal smear results and their relationship with risk factors. RESULTS: A total of 64 patients were included from January 2005 to December 2006. In the overall series, 25 patients have been diagnosed with abnormal anal cytology: 9 atypical squamous cells of undetermined significance (ASCUS), 15 low-grade and 1 high-grade squamous intraepithelial lesions. There were no significant associations between abnormal cytology results and the presence of anal condyloma (p = 0.22). Neither were there statistical associations found with high risk-HPV infection (p = 0.84), HIV infection (p = 0.98) or tobacco use (p = 0.14). CONCLUSIONS: Our diagnostic protocol of anal intraepithelial neoplasia revealed 25% of patients with pre-invasive lesions of squamous anal cancer.

Although the high mortality rate from infectious causes in asplenic patients has been well known since the beginning of the twentieth century, rates of antibiotic prophylaxis in these patients continue to be worryingly low. Consequently, we reviewed the causes of these high mortality rates with a view to recommending preventive measures. The attitude to prophylaxis in these patients depends on age and the cause of splenectomy both in vaccination and antibiotic prophylaxis. The immune status of these patients is decisive in antibiotic prophylaxis, as this treatment will differ in patients splenectomized after a traffic accident and in those splenectomized for lymphoma.

Introducción La observación es el patrón oro del tratamiento de heridas de arma blanca en pacientes estables. El objetivo del estudio fue analizar el valor de la exploración física inicial y de las exploraciones complementarias ante la necesidad de cirugía, para disminuir tiempos de observación. Material y métodos Estudio retrospectivo de un registro prospectivo de pacientes politraumáticos, seleccionando heridas de arma blanca troncales. Se analizan parámetros clínicos y diagnósticos. La variable principal es la necesidad de cirugía. Resultados Entre 2006 y 2009 se incluyó a 198 pacientes, con injury severity score medio de 7,8 ± 7 y mortalidad del 0,5%. El 52% sufrieron heridas múltiples que se distribuyeron en cervicales 23%, torácicas 46% y abdominales 31%. Precisaron intervención quirúrgica 73 pacientes (37%), siendo el 59% inmediata, 27% precoz y 14% tardía. La necesidad de intervención se asoció a un menor revised trauma score, evisceración, hemorragia activa o constatación de herida penetrante. Las hemoglobinas iniciales, a las 2 y 12 h fueron significativamente inferiores en pacientes quirúrgicos. La tomografía computarizada (TC) positiva se asoció a intervención. Un 18% de pacientes presentaron complicaciones, concentradas en los pacientes quirúrgicos. Las intervenciones tardías no presentaron más complicaciones que las inmediatas (p = 0,72). El 10% de los pacientes con exploración física y complementarias normales precisaron cirugía y el 6% desarrollaron complicaciones. Conclusión Ningún parámetro fisiológico o analítico guía de forma individual la necesidad de intervención. La exploración física seriada es la maniobra diagnóstica más importante para decidir intervención, pero la TC puede usarse de forma liberal. Una observación de 24 h es recomendable en pacientes con heridas penetrantes (AU)

Introducción. La neoplasia intraepitelial anal es una lesión precursora del carcinoma escamoso anal. Se considera población en riesgo de padecer esta lesión a los pacientes con condilomas anogenitales, historia previa de displasia de cérvix, infección por VIH y en general los pacientes con infección por el VPH. El objetivo de este estudio es analizar los resultados de la aplicación de un protocolo diagnóstico de neoplasia intraepitelial anal en población de riesgo mediante el empleo de citología anal. Material y método El protocolo diagnóstico de neoplasia intraepitelial anal consistió en realizar una anamnesis estructurada, exploración física y citología anal, la cual se interpretó mediante los criterios de Bethesda. En este estudio observacional de corte transversal se analizan los resultados de diagnóstico de neoplasia intraepitelial anal y su asociación con factores de riesgo. Resultados Se incluyó a 64 pacientes en los que se diagnosticaron 25 alteraciones citológicas: 9 alteraciones citológicas de significado incierto o ASCUS, 15 casos de neoplasia intraepitelial anal de bajo grado y 1 de alto grado. Al relacionar la presencia de alteraciones en la citología anal con los factores de riesgo conocidos, no hubo asociación estadísticamente significativa con la presencia de condilomas (p=0,22), infección por VPH de alto riesgo (p=0,84), infección por VIH (p=0,98) o tabaquismo (p=0,14).Conclusiones La aplicación de un protocolo de detección de neoplasia intraepitelial anal en población de riesgo ha permitido detectar un 25% de pacientes con lesiones precursoras de carcinoma anal (AU)
Introduction. Anal intraepithelial neoplasia is a precursor condition of squamous anal carcinoma. The groups at risk of this lesion are patients with anogenital condylomata, cervical dysplasia, human immunodeficiency virus infection and, in general, patients with HPV infection. The aim of this study was to analyse the results of a diagnostics protocol of Anal Intraepithelial Neoplasia in high risk population using anal cytology. Patients and method The protocol is based on a visit in the outpatient department, clinical interview, physical examination and anal cytology evaluated by Bethesda criteria. The cross-sectional observational study was designed to study the anal smear results and their relationship with risk factors .Results A total of 64 patients were included from January 2005 to December 2006. In the overall series, 25 patients have been diagnosed with abnormal anal cytology: 9 atypical squamous cells of undetermined significance (ASCUS), 15 low-grade and 1 high-grade squamous intraepithelial lesions. There were no significant associations between abnormal cytology results and the presence of anal condyloma (p=0.22). Neither were there statistical associations found with high risk-HPV infection (p=0.84), HIV infection (p=0.98) or tobacco use (p=0.14).Conclusions Our diagnostic protocol of anal intraepithelial neoplasia revealed 25% of patients with pre-invasive lesions of squamous anal cancer (AU)

A pesar de que desde principios del siglo xx se conoce la alta mortalidad por infección entre los pacientes esplenectomizados, aún hoy las tasas de profilaxis antibacteriana en estos pacientes siguen siendo preocupantemente bajas. Por ello se planteó una búsqueda sobre la situación actual de la cuestión para elaborar unas recomendaciones aplicables a los pacientes esplenectomizados. Se expone la actitud profiláctica ante este tipo de pacientes dependiendo de su edad y el motivo de la esplenectomía, tanto de vacunación como de antibioterapia. El estado inmunitario del paciente es muy importante en la necesidad de profilaxis antibiótica, pues no seguirán la misma pauta un paciente sometido a esplenectomía tras un accidente de tráfico y un paciente hematológico (AU)
Although the high mortality rate from infectious causes in asplenic patients has been well known since the beginning of the twentieth century, rates of antibiotic prophylaxis in these patients continue to be worryingly low. Consequently, we reviewed the causes of these high mortality rates with a view to recommending preventive measures. The attitude to prophylaxis in these patients depends on age and the cause of splenectomy both in vaccination and antibiotic prophylaxis. The immune status of these patients is decisive in antibiotic prophylaxis, as this treatment will differ in patients splenectomized after a traffic accident and in those splenectomized for lymphoma (AU)
