Diagnostic and therapeutic cholangioscopy in biliary diseases: a prospective study in Peru / Uso diagnóstico y terapéutico de la colangioscopía en enfermedades de la vía biliar: un estudio prospectivo en Perú

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.

Histoplasmosis del colon y recto en un paciente de Perú / Colon and rectum histoplasmosis in a patient from Peru

Se reportó un caso de varón de 52 años con historia de 3 meses caracterizada por pujo, tenesmo, hematoquezia, dolor al defecar, disminución de 18 kg de peso, fiebre, secreción fecaloidea y purulenta a través de orificio perianal. A la colonoscopía se evidencian múltiples úlceras en colon ascendente, transverso y descendente. También en recto se aprecia lesión elevada de aproximadamente 5 cm. Las biopsias de dichas lesiones fueron coloreadas con hematoxilina-eosina y tinción de Gomori-Grocott demostrando múltiples macrógafos conteniendo microorganismos compatibles con histoplasmosis. Las pruebas para ELISA VIH, HTLV I-II fueron negativas. La histoplasmosis del colon y recto en paciente inmunocompetente es extremadamente rara, habiéndose reportado pocos casos.

We report a case of a male patient of 52 years old with a 3 months history of pushing, tenesmus, hematochezia, pain while defecating, lost of 18 kg of weight, fever, fecaloid and purulent discharge through an perianal hole. During the colonoscopy procedure, we found many ulcers in the ascending, transverse and descending colon.We also found an elevated lesion of about 5 cm in the rectum. We used hematoxylin - eosin and Gomori-Grocott stain in the biopsies and identified many microorganisms inside macrophages which were compatible with histoplasmosis. ELISA tests for HIV, HTLV I- II were negative. Colon and rectal histoplasmosis in an immunocompetent patient is extremely rare. There are few cases of colonic histoplasmosis reported.
