Resultados de una encuesta nacional sobre el manejo de los pacientes diagnosticados de diverticulitis aguda no complicada / Results of a national survey about the management of patients with acute uncomplicated diverticulitis

Introducción: El manejo de los pacientes diagnosticados de diverticulitis aguda no complicada ha evolucionado en los últimos años, y según diversas guías clínicas internacionales actuales, el tratamiento ambulatorio y sin antibioterapia puede ser utilizado en pacientes seleccionados. El objetivo de este estudio es evaluar la adhesión de los distintos centros nacionales a estas y otras recomendaciones en esta enfermedad. Métodos: Se realizó una encuesta online a nivel nacional que se dio a conocer a través de diversas aplicaciones informáticas y se analizaron estadísticamente los resultados obtenidos. Resultados: Participaron 104 cirujanos, representando 69 centros hospitalarios nacionales. En el 82,6% de los centros, se realiza manejo ambulatorio de los pacientes diagnosticados de diverticulitis aguda no complicada. El 23,2% de los centros tiene implantado un protocolo de tratamiento sin antibioterapia en pacientes seleccionados, mientras que en los centros que no siguen estas recomendaciones, las razones principales son las dificultades logísticas para su desarrollo (49,3%) y la ausencia de evidencia actual para ello (44,8%). Se han encontrado diferencias estadísticamente significativas al comparar la implantación de dichos protocolos entre centros con unidades acreditadas avanzadas y aquellas que no, con mayores tasas de manejo ambulatorio y sin antibioterapia en los centros acreditados avanzados (p≤0,05). Conclusiones: A pesar de ser una enfermedad muy frecuente, existe mucha heterogeneidad en su tratamiento a nivel nacional, por lo que sería recomendable la unificación de criterios diagnósticos y de tratamiento mediante la colaboración de las sociedades científicas y la simplificación de la puesta en marcha de protocolos hospitalarios.(AU)

Introduction: Management of patients diagnosed of acute uncomplicated diverticulitis has evolved lately and according to the latest guidelines, outpatient treatment and management without antibiotherapy may be used in selected patients. The aim of this study is to evaluate the adhesion among national centres to these and others recommendations related to this pathology. Methods: An online national survey, that has been broadcast by several applications, was performed. The results obtained were statistically analysed. Results: A total of 104 surgeons participated, representing 69 national hospitals. Of those, in 82.6% of the centers, outpatient management is performed for acute uncomplicated diverticulitis. 23.2% of the hospitals have a protocol stablished for treatment without antibiotherapy in selected patients. Centers that do not follow these protocols allege that the mean reasons are the logistic difficulties to set them up (49.3%) and the lack of current evidence for it (44.8%). Significative statistical differences have been found when comparing the establishment of such protocols between centers with advanced accredited units and those who are not, with higher rates of outpatient management and treatment without antibiotics in accredited units (P≤.05). Conclusions: In spite that this a very common disease, there is a huge national heterogeneity in its treatment. This is why it would adviseable to unify diagnostic and treatment criteria by the collaboration of scientific societies and the simplification of the development of hospitalary protocols.(AU)

Estudio observacional nacional sobre tratamiento quirúrgico de fístula anal: ¿tiene impacto en los resultados el tipo de hospital? / National observational study about the surgical treatment of anal fistula: does the kind of hospital modify the results?

Introducción: En algunos procedimientos quirúrgicos se ha demostrado que la centralización en hospitales de alto volumen mejora los resultados obtenidos. Sin embargo, este punto aún no ha sido estudiado en los pacientes que son intervenidos por una fístula anal (FA). Material y métodos: Se realizó un estudio multicéntrico retrospectivo en el que se incluyeron los pacientes operados de FA durante el año 2019 en 56 centros españoles. Se hizo un análisis uni y multivariante para analizar la relación entre el tamaño del lugar, el porcentaje de curación de la fístula y el desarrollo de incontinencia fecal (IF). Resultados: Se incluyeron en el estudio a 1.809 pacientes. La cirugía se llevó a cabo en un hospital pequeño en 127 usuarios (7,0%), uno mediano en 571 (31,6%) y uno grande en 1.111 (61,4%). Tras un seguimiento medio de 18,9 meses, 72,3% de los participantes (1.303) se consideraron curados y 132 (7,6%) presentaron IF. El porcentaje de los rehabilitados de la FA fue de 74,8, 75,8 y 70,3% (p = 0,045) en los centros pequeño, mediano y grande, respectivamente. En cuanto a la IF no se evidenciaron diferencias significativas según el tipo de lugar (4,8, 8,0 y 7,7%, respectivamente, p = 0,473). En el análisis multivariante no se observó relación entre el tamaño del hospital y la curación de la fístula o el desarrollo de IF. Conclusión: Los resultados de curación e IF posoperatoria en los pacientes sometidos a una cirugía por FA fueron independientes del volumen hospitalario.(AU)

Introduction: Performing the surgical procedure in a high-volume center has been seen to be important for some surgical procedures. However, this issue has not been studied for patients with an Anal Fistula (AF). Material and methods: A retrospective multicentric study was performed including the patients who underwent AF surgery in 2019 in 56 Spanish hospitals. A univariate and multivariate analysis was performed to analyse the relationship between hospital volume and AF cure and Fecal Incontinence (FI). Results: 1809 patients were include. Surgery was performed in a low, middle, and high-volume hospitals in 127 (7.0%), 571 (31.6%) y 1111 (61.4%) patients respectively. After a mean follow-up of 18.9 months 72.3% (1303) patients were cured and 132 (7.6%) developed FI. The percentage of patients cured was 74.8%, 75.8% and 70.3% (p=0.045) for low, middle, and high-volume hospitals. Regarding FI, no statistically significant differences were observed depending on the hospital volume (4.8%, 8.0% and 7.7% respectively, p=0.473). Multivariate analysis didńt observe a relationship between AF cure and FI. Conclusion: Cure and FI in patients who underwent AF surgery were independent from hospital volume.(AU)

Classifying early-onset colorectal cancer according to tumor location: new potential subcategories to explore.

Early-onset Colorectal Cancer (ECRC) represents a significant and increasing proportion of Colorectal Cancer (CRC), but it is a heterogeneous entity that probably encompasses specific subclasses. On the premise that the carcinogenetic mechanism and progression of CRC may differ with location, we analyzed molecular and clinical characteristics of ECRC according to tumor location in order to identify more homogeneous subgroups of CRC. Right-sided ECRC is a subset in which most Lynch Syndrome cases are found, with earlier stages at diagnosis and better prognosis. At this location the CpG Island Methylator Phenotype (CIMP) is predominant and Chromosomal Instability (CI) is rare. Left-sided ECRC appears as a transitional or intermediate location, except for CI tumors, that seem to predominate at this location. Finally, rectal ECRC shows Microsatellite Stability, CIMP low-0 and low CI - with recurrent altered chromosomal regions in common with left-sided ECRC-, possibly in relation with Microsatellite And Chromosomal Stable tumors, but with an unexpected familial component and worse prognosis. All this suggest that the molecular basis of ECRC varies with tumor location, which could affect the clinical management of patients.
