[Therapy for early gastric cancer with submucosal endoscopic disection using the IT-Knife 2]. / Tratamiento endoscópico de cancer gástrico temprano mediante disección endoscópica sub-mucosa (DES) usando el IT-Knife 2.

70 years old woman, without history of illness, came to the Digestive Endoscopic Center of the Gastroenterology department of Arzobispo Loayza hospital, with the diagnosis of Abdominal pain syndrome, in which Upper Endoscopy was practiced. Upper endoscopy concludes the diagnosis of a malignant lesion probably an Early gastric cancer type IIa+IIc, which was confirmed with pathology. Endoscopic treatment was done with Endoscopic submucosal dissection (ESD). The lesion was totally removed, in accordance with the pathologist. Endoscopic controls at 10 weeks showed retractable red scar and a negative biopsy for neoplasm. This case is reported for being the first one published in our literature in which therapeutic ESD with IT-Knife2, was done in Early Gastric cancer.

PCRE: ampulotomía o fistulotomía suprapapilar con needle knife para acceder a la vía biliar en canulación dificil / ERCP: ampulotomy or suprapapillary fistulotomy with needle knife to access bile ductin difficult cannulation

INTRODUCCIÓN: la canulación profunda de la via biliar principal es requisito para una Pancreato-colangiografía Retrograda Endoscópica (PCRE) de carácter terapéutico. El pre corte es una técnica practicada en casos de canulación difícil. Objetivo: Reportar los casos de pacientes con canulación difícil y fistulotomia suprapapilar como un método para la canulación selectiva del colédoco. Reportar la eficacia, hallazgos demográficos, endoscópicos y complicaciones de éste procedimiento. MATERIAL Y MÉTODOS: estudio prospectivo, descriptivo y observacional de casos. Se ha realizado en 93 pacientes sometidos a PCRE con canulación difícil en quienes se practicó el pre corte tipo Fistulotomia, en un Centro privado de Endoscopia Digestiva del 2000 al 2010 en Lima. RESULTADOS: En 1205 (100%) CPRE se hicieron 1152 (96%) papiloesfinterotomias, de éstos en 93 casos (8%) casos se hizo fistulotomia previa a la papiloesfinterotomia. El grupo atareo más frecuente fue de 61 a 70 años, la relación F:M, 2.4:1. La eficacia fue 96%, los hallazgos endoscópicos más frecuentes fueron Odditis, impactación de cálculo y la presencia de ampuloma, los diagnósticos finales fueron enfermedad litiásica (34%), seguida de la Odditis con o sin litiasis coledociana (29%), en el 75% de casos se realizó terapéutica, el 8.5% de casos presentó complicaciones (pancreatitis y sangrado). No se registró perforaciones ni colangitis. CONCLUSIONES: en esta serie la fistulotomia en casos de canulación difícil es eficaz, es más frecuente en casos de Odditis, cálculo impactado y ampuloma y las complicaciones son bajas. RECOMENDACIONES: el pre corte tipo fistulotomia está dirigida a pacientes que requieren PCRE terapéutica, la decisión de realizarla debe ser precoz, la firma de un consentimiento informado es primordial.

INTRODUCTION: Biliary conducts deep cannulation is a requirement for therapeutic Endoscopic Retrograde Cholangio-Pancreatography (ERCP). The pre-cut papillotomy is a technique for difficult cannulation cases. Aims: Report cases of hard cannulation and suprapapilar fistulotomy as a method for selective common bile duct cannulation. Report efficacy, demographic and endoscopic findings and complications of this procedure. MATERIALS AND METHODS: Observational, descriptive and prospective study of cases. Sample of 93 patients who had a difficult cannulation ERCP, in which suprapapilar fistulotomy pre-cut type was done, in a private digestive endoscopic center between 2000 and 2010 in Lima, Peru. RESULTS: 1205 (100%) ERCP were made 1152 (96%) papillosphincterotomies. Fistulotomy was done in 93 cases (8%) of these papillosphincterotomies. The most prevalent age group was 61 to 70 years old, the female-male proportion was 2.4:1. The efficacy was 96%. The most prevalent endoscopy findings were odditis, gallstone impactation and ampulloma presence, final diagnosis were lithiasic disease (34%), Odditis with or without common bile duct lithiasis (29%). Therapeutic ERCP was done in 75% of the cases, 8.5% showed complications (pancreatitis and bleeding). No perforation or cholangitis were registered. CONCLUSIONS: In this case series, fistulotomy in difficult cannulation procedures had good efficacy. Is most prevalent in cases with odditis, gallstone impactation and ampulloma. Complications of the procedure are low. RECOMMENDATIONS: The fistulotomy type of pre-cut is leaded for patients who require therapeutic ERCP. The decision for doing the procedure must be precocious and informed consent is primordial.

Tratamiento endoscópico de cáncer gástrico temprano mediante disección endoscópica sub-mucosa (DES) usando el IT-KNIFE 2 / Therapy for early gastric cancer with submucosal endoscopic disection using the IT-knife 2

Mujer de 70 años de edad, sin antecedentes de importancia. Acude al centro de Endoscopía Digestiva del servicio de Gastroenterología del Hospital Nacional ôArzobispo Loayzaõ donde se le practica Endoscopia alta, indicada por presentar Síndrome Doloroso abdominal. La endoscopia alta concluye como presencia de lesión en relación a Cáncer gástrico precoz tipo IIa+IIc que se confirma con la patología. Se realiza tratamiento endoscópico mediante Disección endoscópica sub-mucosa (DES) usando el IT-Knife2, lográndose extirpar la lesión en su totalidad conforme confirma el estudio de pieza resecada. Control endoscópico a las 10 semanas muestra cicatriz roja y la biopsia negativa para neoplasia. Se reporta este caso por ser el primero publicado en nuestro medio en el que se usó DES curativa.

Una gran Brunneroma como causa inusual de hemorragia digestiva / Big Brunneroma as unusual cause of intestinal bleeding

Nosotros reportamos un gran hamartoma de las glándulas de Brunner (8 x 2.5 x 2 cm) que se presento en una mujer de 75 años con una historia de 10 días de melena. El estudio endoscópico identificó una tumoración ovoide, móvil que ocupaba parcialmente la luz duodenal. La biopsia endoscópica fue negativa porque el tumor estuvo localizado completamente en la submucosa. En el acto operatorio, un tumor polipoideo fue encontrado en la segunda porción del duodeno por encima de la ampolla de Vater. Se revisan las características clínicas, endoscópicas, radiológicas, histológicas y quirúrgicas del hamartoma de las glándulas de Brunner.
