Seguridad y eficacia del drenaje guiado por endosonografía de colecciones pancreáticas usando prótesis plásticas y metálicas tipo LAMS / Safety and efficacy of EUS-guided drainage of pancreatic fluid collections using plastic and lumen apposing metal stents (LAMS)

Background: Pancreatic fluid collections (PFC) are associated with severe acute pancreatitis. After maturation (after 4 weeks) they are classified as pancreatic pseudocyst (PP) and walled-off necrosis (WON). Endoscopic management is associated with lower morbidity and mortality compared with surgery. Aim: To describe the experience of EUS-guided drainage PFC drainage using plastic stent (PS) or metal stent (lumen apposing metal stents, or "LAMS"). Methods: Retrospective, observational study, between 2016-2019. Results: 17 patients in total. 8 cases were symptomatic PP and 9 were WON. Age 12-72 years. 12 cases in men. Indications: abdominal pain 5 cases and infection 11. The 8 cases of PFC were drained successfully using PS, without adverse effects. Regarding WON drainage, 3 cases were managed with PS and 6 with LAMS. In 5 cases, complementary endoscopic necrosectomy was required. A patient with LAMS required complementary surgical cleaning ("step-up") to treat collections far from the LAMS. Complications: one case of PS presented pigment occlusion with superinfection and another case presented migration to the stomach. Regarding LAMS, one case presented self-limited bleeding, another case presented obstruction of the stent with infection, which was managed endoscopically and with antibiotics. Conclusion: The endoscopic management of PFC is effective and safe, with plastic and metal stent (LAMS). The choice of type of stent depends on the characteristics of PFC (liquid vs solid), center experience and costs.

Introducción: Las colecciones pancreáticas (CP) se asocian a pancreatitis agudas graves. Luego de su maduración (después de las 4 semanas) se clasifican en pseudoquistes (PQ) y necrosis encapsulada (NE). El manejo endoscópico se asocia a menor morbimortalidad comparado con el quirúrgico. Objetivo: Describir la experiencia del drenaje de CP mediante el uso de prótesis plásticas (PP) o metálicas (lumen apposing metal stents, o "LAMS") mediante endosonografía. Método: Estudio retrospectivo, observacional, entre 2016-2018. Resultados: 17 pacientes en total. Ocho casos fueron PQ sintomáticos y 9 NE. Edad 12-72 años (12 casos en hombres). Indicaciones: dolor abdominal 5 casos e infección 11. Los 8 casos de PQ fueron drenados exitosamente con PP, sin efectos adversos. En relación con el drenaje de NE, 3 casos fueron manejados con PP y 6 con LAMS. En 5 casos se requirió necrosectomía endoscópica complementaria. Un paciente con LAMS requirió aseo quirúrgico complementario por colecciones alejadas al LAMS. En relación con las complicaciones, un caso de PP presentó oclusión del pigtail con sobreinfección y otro presentó migración al estómago. Respecto a LAMS, un caso presentó sangrado autolimitado y otro caso obstrucción de la prótesis con sobreinfección, que fue manejada endoscópicamente y con antibióticos. Conclusión: El manejo endoscópico de las CP es efectiva y segura, tanto con prótesis plásticas como metálicas (LAMS). La elección de la prótesis depende de las características de la lesión (líquido vs sólido), experiencia del centro y costos.

Consumo e desempenho de ovinos alimentados com silagens de cana-de-açúcar tratadas com óxido de cálcio e cloreto de sódio / Intake and performance of lambs fed with sugarcane silages treated with whitewash and sodium chloride

Avaliaram-se o consumo e o desempenho de ovinos alimentados com silagens de cana-de-açúcar tratadas com óxido de cálcio (CaO) e cloreto de sódio (NaCl). Utilizaram-se sete tratamentos: controle (silagem sem aditivo), silagens com 0,5; 1,0 e 1,5% de CaO e silagens com 0,5; 1,0 e 2,0% de NaCl, com quatro repetições. Os animais consumiram maior quantidade de matéria seca e de nutrientes digestíveis totais quando se adicionou 0,5% de NaCl ou ainda 1,0 e 1,5% de CaO. Quanto à fibra em detergente neutro e à proteína bruta, observou-se maior consumo quando se adicionou 0,5% de NaCl ou 1,0% de CaO. Não foi observado efeito da dieta sobre o ganho médio diário de peso. A adição de 0,5% de cloreto de sódio e 1,0% de óxido de cálcio à silagem de cana-de-açúcar resultou em aumento no consumo e melhora no desempenho de ovinos.

The intake and performance of lambs fed with sugarcane silages treated with whitewash and chloride sodium were evaluated. Seven treatments were used: untreated silage (control); silages treated with 0.5; 1.0 and 1.5% of CaO (whitewash); and silages treated with 0.5; 1.0 and 2.0% of NaCl, with four replicates per treatment. The animals were fed a higher amount of dry matter and total digestible nutrients when the sugarcane silages were treated with 0.5% of NaCl, 1.0 and 1.5% of CaO. The intake of neutral detergent fiber and crude protein increased when the lambs were fed silages treated with 0.5% of NaCl and 1.0% of CaO. The average daily gain did not differ among treatments. The inclusion of 0.5% of sodium chloride and 1.0% of whitewash in sugarcane silages increased the intake and improved the performance of lambs.

Contenidos de Anatomía en Diseños de Aprendizaje Dispuestos en LAMS e Integrado a Moodle / Anatomy Contents in Learning Designs Displayed in LAMS and Integrated to Moodle

Este trabajo trata la experiencia del uso de LAMS en procesos de aprendizaje e-learning para el área de la salud. Se trabajó con contenidos de anatomía del hígado humano, siguiendo estándares educativos y metodologías necesarias para crear Diseños de Aprendizaje (LD) y recursos educativos de calidad e interoperables. El Instituto de Anatomía, Histología y Patología fue responsable del diseño e implementación de Objetos de Aprendizaje (OAs) en anatomía de hígado (con Macromedia flash), mientras el Instituto de Informática se encargó de abordar la gestión y proceso del recurso pedagógico, integrando un especialista (LAMS y Moodle) para el diseño y gestión de aprendizaje. LAMS fue usado para crear actividades de aprendizaje basado en LD integrado a Moodle, como parte de un curso de estudiantes de medicina. La encuesta de satisfacción aplicada a estos estudiantes mostró, que casi el 70 por ciento de ellos consideró las actividades y objetivos comprensibles y suficientemente detallados, que las evaluaciones fueron coherentes con los contenidos y que existe aprendizaje colaborativo. Así mismo el 67 por ciento aseguró que volvería a usar un plan de lección en esta modalidad y sólo un 33 por ciento lo haría ocasionalmente.
