RESUMO

Introduction: Cholangioscopy is a test that allows the evaluation of the biliary epithelium. It is used for diagnosis and management of biliary diseases. Objectives: Determine the success rate of complete removal of difficult stones with the use of laser lithotripsy through cholangioscopy as well as its complications. Determine the visual impression accuracy of bile duct injuries. Materials and methods: This is a prospective and descriptive study. We included 39 patients between July 2016 and July 2017 with diagnosis of difficult stones in the biliary tract and indeterminate stenosis of the biliary tract that were submitted to cholangioscopy. Results: Success rate of complete removal of difficult stones was 65.3%, there was one complication. Two laser sessions were required in 4 of the 17 patients who obtained complete removal of the stones. The visual impression accuracy of lesions in the bile duct to determine malignancy coincided in all cases with the final diagnosis of the patient. Conclusions: Laser lithotripsy allows a safe and effective treatment of the difficult stones of the bile duct. Precession of visual impression of lesions in the bile duct is very high.


Introducción: La colangioscopía es un examen que permite evaluar la luz biliar, el epitelio biliar y sirve para diagnóstico y manejo de enfermedades de la vía biliar. Objetivos: Determinar la tasa de éxito de remoción completa de cálculos difíciles con el uso de litotripcia con láser a través de la colangioscopía asi como las complicaciones de ésta. Determinar la precisión de impresión visual de lesiones de la vía bilar. Materiales y métodos: Estudio prospectivo, descriptivo. Se incluyeron a 39 pacientes entre Julio 2016 a Julio 2017 con diagnóstico de cálculo difícil en la vía biliar y estenosis indeterminada de la vía biliar que fueron sometidos a colangioscopía. Resultados: La tasa de éxito de remoción completa de cálculos difíciles fue de 65,3% con una complicación. Se requirió de dos sesiones con láser en 4 de los 17 pacientes que obtuvieron remoción completa de cálculos. La precisión de impresión visual de lesiones en la vía biliar para determinar malignidad coincidió en todos los casos con el diagnóstico final del paciente. Conclusiones: La colangioscopía con uso de litotripcia con láser permite un tratamiento seguro y eficaz en los cálculos difíciles de la vía biliar. La precesión de la impresión visual de lesiones en la vía biliar es muy alta.

RESUMO

Objetivo: Determinar los hallazgos clínicos, endoscópicos e histopatológicos que se asocian con el hallazgo endoscópico de gastritis nodular en pacientes atendidos en el servicio de gastroenterología del Hospital Nacional Arzobispo Loayza durante el periodo de febrero a julio 2014. Metodología: Estudio observacional, analítico comparativo, de corte transversal. La muestra se obtuvo de los pacientes que acudieron al centro de endoscopia del HNAL, se incluyeron 110 pacientes, los cuales conformaron 2 grupos: Grupo de estudio: 55 pacientes con gastritis nodular y Grupo Comparativo: 55 pacientes con gastritis superficial, de febrero a julio del 2014. Para el análisis descriptivo de las variables cuantitativas se usaron medidas de tendencia central y de dispersión; y para las variables cualitativas se usaron frecuencias absolutas y relativas. Para el análisis inferencial se empleó la prueba de Chi-cuadrado con un nivel de confianza del 95 por ciento. Resultados: La edad promedio de los pacientes del grupo de gastritis nodular fue de 33.5±12.8 años, siendo de género femenino un 80 por ciento. Los manifestaciones clínicas en el grupo de estudio con gastritis nodular fueron: 83.6 por ciento síntomas dispépticos, el 5.5 por ciento dolor abdominal y 1.8 por ciento regurgitaciones y/o pirosis; mientras que los pacientes del grupo de gastritis superficial presentaron en un 45.5 por ciento síntomas dispépticos, 5.5 por ciento dolor abdominal, 32.7 por ciento regurgitaciones y/o pirosis, 1.8 por ciento dolor abdominal mas regurgitaciones, 5.5 por ciento regurgitaciones más síntomas dispépticos. En el estudio comparativo entre ambos grupos el valor p fue significativo (p<0.01) para los síntomas dispépticos. Los antecedentes patológicos hallados en los pacientes con gastritis nodular fueron: asma (3.6 por ciento), enteroparasitosis (3.6 por ciento), la rinitis alérgica (1.8 por ciento) y urticaria crónica (1.8 por ciento). Entre los hallazgos endoscópicos se encontró úlcera...


Objective: To determine the clinical, endoscopic and histopathological findings that relate to nodular gastritis in patients treated at the gastroenterology service of Arzobispo Loayza National Hospital, February-July 2014. Methodology: Observational, comparative analytical, cross-sectional. The sample was obtained from the patients attending the endoscopy center HNAL, 110 patients were included, which formed two groups: Study group: 55 patients with nodular gastritis and Comparative group: 55 patients with superficial gastritis, from February to July 2014 for the descriptive analysis of quantitative variables measures of central tendency and dispersion were used; for qualitative variables and absolute and relative frequencies were used. For the inferential analysis, the Chi-square test was used with a confidence level of 95 per cent. Results: The average age of patients in the nodular gastritis was 33.5±12.8 years, and female gender 80 per cent. The clinical manifestations in the study group with nodular gastritis were 83.6 per cent dyspeptic symptoms, abdominal pain 5.5 per cent and 1.8 per cent regurgitation and / or heartburn; while group patients had superficial gastritis in dyspeptic symptoms 45.5 per cent, 5.5 per cent abdominal pain, 32.7 per cent regurgitation and / or heartburn, 1.8 per cent abdominal pain more regurgitations, 5.5 per cent regurgitations more dyspeptic symptoms. In the comparative study between the two groups was significant p-value (p<0.01) for dyspeptic symptoms. The underlying conditions found in patients with nodular gastritis were: asthma (3.6 per cent), intestinal parasites (3.6 per cent), allergic rhinitis (1.8 per cent) and chronic urticaria (1.8 per cent). Among gastric endoscopic findings (7.3 per cent) ulcer and duodenal ulcer (3.6 per cent) for patients with nodular gastritis was found, whereas patients with superficial gastritis duodenal ulcer had only 1.8 per cent. Histopathological findings showed mucinous damage by...
