Nuestra experiencia en el manejo diagnóstico-terapéutico a corto plazo del paciente con displasia anal / Our experience in the short-term diagnostic-therapeutic management of the patient with anal dysplasia

Introducción: La neoplasia intraepitelial anal (NIA) es una lesión premaligna del carcinoma escamoso anal. Los varones VIH que tienen sexo con varones, es la población de riesgo más afectada. La citología y anuscopia son los métodos mejor aceptados para su diagnóstico, aunque es controvertido qué pacientes deben completarlo con una biopsia. Tampoco está bien establecido qué pacientes deben someterse a tratamiento y cuál es el mejor. Con este estudio, queremos exponer nuestra experiencia en el manejo diagnóstico-terapéutico de la NIA a corto plazo. Métodos: Estudio observacional retrospectivo de pacientes con riesgo de NIA con una citología anal alterada a los que se les realizó una anuscopia de alta resolución con biopsia. Tras la confirmación histológica de displasia iniciaron tratamiento con ácido tricloroacético. Se comprobó su efectividad con una citología posterior. Se analizaron las variables demográficas de la muestra y los resultados de las pruebas diagnósticas y de tratamiento. Resultados: La mayoría eran varones VIH positivos (104/115) y el 50% mantenían relaciones sexuales con otros varones. Se incluyeron 115 pacientes con citología anal alterada, de los cuales el 92% presentaron displasia en la biopsia. El 97% con atipia de significado incierto en la citología presentaron displasia histológicamente. El 60% de los pacientes normalizó la citología tras el tratamiento. Conclusión: Se debe considerar de forma sistemática la detección precoz de la NIA en poblaciones de riesgo conocidas. Cualquier anormalidad citológica debe ser biopsiada. El ácido tricloroacético puede ser un tratamiento efectivo consiguiendo un alto porcentaje de regresión, aunque actualmente la información con la que contamos es de bajo nivel de evidencia. (AU)

Introduction: Anal intraepithelial neoplasia (AIN) is a premalignant lesion of anal squamous cell carcinoma. HIV-positive males who have sex with males, are the most affected at-risk population. Cytology and anuscopy are the best accepted methods for its diagnosis, although it is controversial which patients should complete it with a biopsy. Neither which patients should undergo treatment nor which is the best treatment is not well established. With this study, we would like to present our experience in the diagnostic-therapeutic management of AIN in the short term. Methods: Retrospective observational study of patients at risk of AIN with altered anal cytology who underwent high-resolution anuscopy with biopsy. After histological confirmation of dysplasia, they started treatment with trichloroacetic acid. Its effectiveness was verified by subsequent cytology. The demographic variables of the sample and the results of both diagnostic and treatment tests were analyzed. Results: The majority were HIV-positive males (104/115) and 50% had sexual relations with other men. We included 115 patients with altered anal cytology, of whom 92% had dysplasia on biopsy. 97% with atypia of uncertain significance on cytology had histological dysplasia. Cytology normalized after treatment in 60% of patients. Conclusion: Early detection of AIN should be routinely considered in known at-risk populations. Any cytological abnormality should be biopsied. Tricholoroacetic acid can be an effective treatment achieving a high percentage of regression, although currently, the information we have is of low level of evidence. (AU)

Duodenopancreatectomía en ancianos. Evaluación de resultados / Duodenopancreatectomy in the elderly. Evaluation of results

Introducción Con el aumento de la esperanza de vida, cada vez se diagnostican más tumores periampulares resecables en la población geriátrica. A pesar de la disminución de la mortalidad postoperatoria, el debate sobre la relación riesgo-beneficio de la duodenopancreatectomía cefálica (DPC) en ancianos sigue vigente.Objetivo Analizar la morbimortalidad de la DPC en los pacientes mayores de 70 años. Diseño Estudio prospectivo observacional. Pacientes Entre enero de 2005 y diciembre 2010, se realizaron 54 duodenopancreatectomías. Se compararon 2 grupos de pacientes: grupo 1 (pacientes>70 años, n: 24), y grupo 2 (pacientes<70 años, n: 30). Se analizó la morbimortalidad, transfusión, reintervenciones, estancia media y supervivencia. Resultados El grupo>70 años incluyó más pacientes ASA 2 y 3 (p=0,010), y presentaron mayor número de antecedentes personales por paciente (p=0,037). La mortalidad postoperatoria fue superior en el grupo de más edad, aunque sin diferencias significativas (8,3 vs. 3,3%). La morbilidad postoperatoria (45,8 vs. 46,6%), la tasa de reintervenciones (16,6 vs. 13,3%), la estancia hospitalaria (18 vs. 13 días), y la supervivencia a 6 y 12 meses, tampoco presentaron diferencias significativas (84 y 72% vs. 90 y 86%).Conclusiones La edad no parece ser una contraindicación por sí misma para la DPC, si bien los ancianos presentan mayor riesgo de complicaciones debido a los cambios fisiológicos relacionados con el envejecimiento. La disparidad de resultados evidencia la necesidad de disponer de estudios poblacionales de ámbito nacional que aporten una visión global de la morbimortalidad en la DPC (AU)

Introduction With the increase in life expectancy, more and more resectable periampullary tumours are being diagnosed in the geriatric population. Despite the decrease in post-operative mortality, there continues to be a debate on the risk-benefit of cephalic duodenopancreatectomy (CPD) in the elderly. Objective To analyse the morbidity and mortality of CPD in patients over 70 years-old. Design Prospective observational study. Patients A total of 54 duodenopancreatectomies were performed between January 2005 and December 2010. Two groups of patients were compared: Group 1 (patients>70 years-old, n: 24), and Group 2 (patients<70 years-old, n: 30). The morbidity and mortality, transfusion, reinterventions, mean hospital stay, and survival were analysed. Results The>70 years group included more ASA 2 and 3 patients (P=.010), and had a higher number of previous medical problems per patient (P=.037). The post-operative mortality was higher in the older age group, although the difference was not significant (8.3 vs 3.3%). There were also no significant differences in post-operative morbidity (45.8 v. 46.6%), reintervention rate (16.6 vs 13.3%), length of hospital stay (18 vs 13%), and survival at 6 and 12 months (84 and 72% vs 90 and 86%).Conclusions Age, in itself, does not seem to be a contraindication for CPD, but the elderly do have a higher risk of complications due to the physiological changes associated with ageing. The disparity of results demonstrates the need for more population studies at national level that may give an overall view of morbidity and mortality in CPD (AU)
