Valoración de la respuesta endoscópica al tratamiento con argón plasma en la rectitis actínica crónica / No disponible

Objetivo: valorar la mejoría endoscópica tras el tratamientocon argón plasma utilizado para el control sintomático de las rectitisactínicas crónicas.Diseño y pacientes: estudio prospectivo de 48 meses de duración,con 38 pacientes (26 hombres y 12 mujeres, con edadmedia de 70,9 ± 7,38 años). Todos presentaban algún grado derectorragia y/o anemia. Se realizaron entrevistas clínicas, analíticasy sesiones endoscópicas con argón, de forma periódica mensual,hasta la normalización analítica y cese del sangrado, con unseguimiento posterior de 24 meses. Para valorar la mejoría se utilizaronparámetros analíticos, gradación de sangrado (Chutckan)y un índice endoscópico.Resultados: el tiempo medio trascurrido entre el inicio y la finalizacióndel seguimiento fue de 28,5 ± 3,9 meses. La media desesiones administradas por paciente ha sido de 3,6 ± 2,7. Sicomparamos los síntomas antes, después del tratamiento existeuna disminución significativa en el grado de rectorragia según laclasificación de Chutkan (2,29 ± 1,08 vs. 0,59 ± 1,12, p <0,05). Cuando comparamos los valores medios de la hemoglobina,antes y después del tratamiento apreciamos una aumento estadísticamentesignificativo (11,33 ± 3,05 mg/dl vs. 14,014 ±1,29 mg/dl, p < 0,001) así como los valores medios de ferritina(31,15 ± 66, 45 μg/dl vs. 80,60 ± 55,60 μg/dl, p < 0,05). En elíndice endoscópico, también existe una mejoría evidente de laafectación endoscópica tras el tratamiento con respecto a la friabilidad(p < 0,0001) y porcentaje de mucosa afecta (p < 0,0001).Conclusión: el argón plasma es eficaz y la realización del índiceendoscópico es una herramienta útil para valorar la mejoría endoscópicade las lesiones tras el tratamiento

Objectives: to evaluate endoscopic improvement after argonplasma coagulation (APC) in symptomatic patients with chronicradiation proctopathy.Methods and patients: a prospective study of 38 patientswith radiation proctitis (26 males and 12 females, mean age 70.9± 7.38 yrs), and with rectal bleeding and or anemia. We performedmonthly interviews, blood tests, and APC sessions untilrectal bleeding had ceased and hemoglobin and ferritin levels wereimproved, with a follow-up of 24 months. We used blood testing,bleeding scores (Chutckhan’s index), and endoscopic scores toevaluate improvement.Results: mean time between inclusion and follow-up completionwas 28.5 ± 3.9 months. Mean number of sessions per patientwas 3.6 ± 2.7. There was a significant decrease (2.29 ± 1.8vs. 0.59 ± 1.12, p < 0.05) in rectal bleeding (Chutckan score)from baseline after APC. There was a significant increase in hemoglobinlevels (11.3 ± 3.05 vs. 14.014 ± 1.29, p < 0.001) andferritin levels (31.15 ± 66.45 vs. 80.60 ± 55.6, p < 0.05) frombaseline after APC. Also, there was improvement in the endoscopicindex at the end of treatment, as well as in friability (p <0.0001) and involved surface area (p < 0.0001).Conclusion: argon plasma coagulation is an effective technique,and the endoscopic index is a useful tool to evaluate endoscopicimprovement

[Cholecystectomy: a choice technique in biliary microlithiasis]. / La colecistectomía: técnica de elección en la microlitiasis biliar.

The purpose of our study is to show results obtained after a cholecystectomy on 25 patients in order to present a suggestive clinic of bile origin and a positive result for determination of microcrystals in the bile probe even in the case of negative radiologic diagnoses (echography, cholecystography). Out of 25 patients operated on the following results were obtained: microscopic cholelithiasis in 12, granular cholelithiasis in 3, acute cholecystitis in 2, cholesterolosis in 2 and without pathologic findings in 6 patients after an observation period of 24 months following the operation it was demonstrated that almost all the patients (96%) had no symptoms. On the other hand, the above mentioned results are compared to the findings obtained during an observation period of a group of 34 patients with positive probe results with the same clinic characteristics and not having been operated on refusing the operation suggested.
