Objetivos: Describir la tasa de éxito técnico, clínico (definido como posibilidad de uso de la sonda) así como complicaciones inmediatas, tempranas (30 días) o tardías (90 días) de pacientes que se realizó PEJ con técnica &#8220;Pull&#8221; por enteroscopia asistida por dispositivo, variedad monobalón.  Métodos: Estudio descriptivo de cohorte retrospectiva de 6 pacientes a los que se realizó PEJ desde enero 2017- mayo 2019. Estadística descriptiva empleando medianas y rangos para variables continuas, así como porcentajes para variables categóricas.  Resultados: El 67% fueron mujeres con una mediana de edad 75.5 años, la afección neurológica fue la indicación en el 50% seguido por OTS en 33%, tres pacientes tenían anatomía modificada. La duración promedio del procedimiento fue 61 min con tasa de éxito técnico de 100% y tasa de éxito clínico 100% permitiendo el inicio de la nutrición enteral en las primeras 24hrs, no se reportaron complicaciones inmediatas-tempranas o tardías.  Conclusiones: Primer serie de casos en México que describe a la PEJ por enteroscopía asistida por dispositivo, variedad monobalón como procedimiento potencialmente seguro y con altas tasas de éxito técnico- clínico.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract  Background: Percutaneous Endoscopic Jejunostomy (PEJ) has been described by Shike since 1987 and is currently the best alternative in patients with gastroparesis, gastric outlet obstruction (GOO) and modified anatomy that require &gt;6 weeks enteral feeding, however it´s still considered a difficult procedure used in few centers. In Mexico there are still no studies reporting the outcomes related to PEJ. We aim to describe the rate of technical and clinical success (defined as the effective use of the PEJ), as well as immediate, early (30 days) or late (90 days) procedure related complications of patients undergoing single-balloon enteroscopy (SBE) for PEJ placement.  Methods: Retrospective analysis of 6 patients undergoing PEJ placement between January 2017 and May 2019. Statistical analysis included descriptive statistics with medians and range for continuous variables, and frequencies and percentages for categorical variables.  Results: 67% were women with a median age 75.5y, neurological condition was the main indication (50%) followed by GOO in 33%, three patients had modified anatomy. The average procedure duration was 61 min with 100% technical success rate and 100% clinical success rate allowing the onset of enteral nutrition in the first 24hrs, no immediate-early or late complications were reported.  Conclusion: This study represents the first Mexican case series of SBE for PEJ placement as a potentially safe procedure and with high rates of technical-clinical success.]]></p></abstract>
