Coagulantes naturales extraídos de Ipomoea incarnata en el tratamiento de aguas residuales industriales en Cartagena de Indias

The main objective of this research is to determine the clotting properties of Ipomoea incarnata in clarifying industrial wastewater. Extraction and characterization of the coagulant were made to check and verify benefits considering the removal percentage compared to other common industrial uses. Jar test was uses to estimate the removal efficiency; analyzing and verifying that the powder obtained from the seeds of Ipomoea incarnata is effective in reducing turbidity in 99.18%. Finally the results reported in this article evidence that advantage of natural coagulants over the chemical ones.El objetivo principal de esta investigación está enmarcado en probar las propiedades coagulantes de la Ipomoea incarnata en la clarificación de las aguas residuales industriales.Para la comprobación y verificación de estos beneficios se realizó  la extracción y caracterización  del coagulante considerando el porcentaje de remoción  frente a otros de uso industrial común, estimando mediante la prueba de jarras la eficiencia de remoción; analizando y constatando  que el  polvo obtenido a partir de las semillas de la Ipomoea incarnata es efectivo en la reducción de la turbidez en un  99,18 %. Finalmente, se evidencia a través de los resultados consignados en este articulo  la gran ventaja que presentan los coagulantes de origen natural frente a los químicos

Conversion of aspireAssist system® to sleeve gastrectomy: Technical video description

Purpose: The AspireAssist System® (Aspire Bariatrics, Inc. King of Prussia, PA) is a new endoscopic procedure used to treat obese patients. The aim of this dedicated video is to present a case that required revision surgery due to failure of the AspireAssist System®, and to show how the cannula was removed from the abdomen, and why sleeve gastrectomy (SG) was a good option for revisional surgery in that patient. We aim to discuss technical aspects. Patient and Methods: A 43-year-old female patient who underwent a placement in 2016. Her initial BMI (body mass index) was 38 kg/m2, with a follow-up period of 26 months. A revisional surgery was performed including dissection of the previous gastric fistula and adhesiolysis from the previous AspireAssist System® placement. A complete dissection of the gastrostomy, including removal of all the system, was done. A decision was made, once the incisura angularis and the placement of a 40 Fch bougie showed that the transection could be performed. SG was done. Patients showed an uneventful postoperative course and 4 months follow-up with 45% EWL. Conclusion: In case of having the device in place, the surgeon must be aware to remove intraoperatively or endoscopically, the device. Surgeons should consider endoscopic removal of the AspireAssist System® before conversion to another procedure (SG or GBP) at least 6 months of the removal. Removal of the AspireAssist System® should be performed endoscopically but direct conversion to another bariatric procedure can be considered, either to SG or GBP depending on the technical intraoperative aspects
