Tumor de células epitelioides perivasculares de íleon. Descripción de un caso / Perivascular epithelioid cell tumor of the ileum. A case report

Los tumores de células epiteliodes perivasculares son tumores de células epiteliales vasculares con características inmunohistoquímicas de músculo liso y células melanocíticas. Los gastrointestinales son infrecuentes. El tratamiento es quirúrgico aunque existen datos que indican buena respuesta a la rapamicina (AU)

Perivascular epithelioid cell tumors (PEComa) are tumors of perivascular epithelioid cells with immunohistochemical features of smooth muscle and melanocytic tumors. The PEComa of the gastrointestinal tract is rare. The treatment is surgical, although there are data that suggest a good response to rapamycin (AU)

Aumento de la incidencia de cáncer colorrectal en la provincia de Salamanca. Comparación de dos periodos: 2004-2006 y 2010-2012 / Increasing incidence of colorectal cancer in the province of Salamanca. Comparison of two periods: 2004-2006 and 2010-2012

Objetivos: comparar incidencia, mortalidad y características epidemiológicas de los pacientes diagnosticados de cáncer colorrectal (CCR) en la provincia de Salamanca entre dos periodos: 2010-2012 y 2004-2006. Métodos: estudio observacional retrospectivo. Incluimos todos los CCR diagnosticados según criterios histopatológicos del 01/01/2004 al 31/12/2006 y del 01/01/2010 al 31/12/2012. Las variables estudiadas fueron género, edad, fecha de diagnóstico y localización del tumor. Se han calculado incidencia acumulada e incidencia específica por grupos de edad comparando los resultados entre periodos. Hemos ajustado las tasas por edad a la población mundial estándar para poder compararla con otras poblaciones. Resultados: detectamos un 38% más de CCR en el periodo de 2010 a 2012 que en el de 2004 a 2006. Las variables (sexo, edad de diagnóstico y localización) han sido similares en ambos grupos. En el periodo de 2010-2012 se realizaron más del doble de colonoscopias que en el de 2004-2006. La mortalidad poblacional por CCR también aumentó, aunque de manera mucho menos importante que la incidencia. Conclusiones: existe un claro aumento de la incidencia del CCR en la provincia de Salamanca entre los años 2004-2006 y 2010-2012 no relacionado con el envejecimiento. El aumento considerable de colonoscopias puede haber sido un factor importante para el aumento en la detección (AU)

Objectives: To compare incidence, mortality and epidemiological characteristics of patients diagnosed with colorectal cancer (CRC) in the province of Salamanca over two different periods: 2010-2012 and 2004-2006. Methods: Retrospective observational study. We include all diagnosed cases of CRC according to histopathological criteria from 01/01/2004 to 31/12/2006 and from 01/01/2010 to 31/12/2012. The studied variables were sex, age, date of diagnosis and tumor location. Cumulative incidence and specific incidence in different age groups were measured and compared between the two periods. The age rates were adjusted to the standard world population so that the results could be compared with those of other populations. Results: We detected 38% more cases of CRC in the 2010-2012 period than in 2004-2006. Variables distribution (sex, age at diagnosis and location) was similar in both groups. More than twice as many colonoscopies were performed in 2010-2012 than in 2004-2006. Population mortality due to CRC also increased, although much less importantly than the incidence of this condition. Conclusions: There has been a clear increase in CRC incidence in the province of Salamanca from 2004-2006 to 2010-2012 which is not related to the ageing of the population. The remarkable increase in colonoscopies may have been an important factor for the increased detection (AU)

Tratamiento endoscópico de varices duodenales con cianoacrilato / Endoscopic treatment of duodenal varices with cyanoacrylate

Introducción: el duodeno es la localización más frecuente de varices ectópicas. Su sangrado es poco frecuente, pero cuando ocurre, es masivo y de difícil control. Material y métodos: descripción retrospectiva de cinco casos clínicos de hemorragia digestiva secundaria a varices duodenales en los años 2011 y 2012, sus características clínicas, diagnóstico endoscópico, tratamiento endoscópico con inyección de cianoacrilato y posterior seguimiento y valoración de resangrado. Resultados: los cinco pacientes fueron tratados con inyección endoscópica de cianoacrilato de los cuales, dos pacientes experimentaron resangrado. Tres de nuestros pacientes fallecieron durante el seguimiento, uno de ellos por hemorragia digestiva. Conclusión: podemos afirmar que el tratamiento endoscópico de las varices duodenales con cianoacrilato es técnicamente factible, y puede ser de ayuda para controlar el episodio inicial de sangrado de este modo ganar tiempo de cara a otros tratamientos definitivos, siempre y cuando el estado del paciente lo permita (AU)

Background: the duodenum is the most common location for ectopic varices. Bleeding is rare, but when it appears, it is massive and difficult to control. Material and methods: retrospective description of five clinical cases of digestive bleeding secondary to duodenal varices that we observed between the years 2011 and 2012, together with their clinical characteristics, endoscopic diagnosis, endoscopic treatment with cyanoacrylate injection and the posterior follow-up and assessment of new bleeding. Results: all five patients were treated with an endoscopic cyanoacrylate injection and two of the patients experienced a digestive rebleeding. Three of the patients died during the follow-up period, only one due to cause digestive bleeding. Conclusion: in conclusion we can state that endoscopic treatment of duodenal varices with cyanoacrylate is technically possible, and it permits us to control the first bleeding before doing other definitive treatments, if the patient condition allows it (AU)
