Description
Summary:The One Anastomosis Gastric Bypass has been developed from the Mini Gastric Bypass procedure as originally described by Robert Rutledge. The modification of the original procedure consists of making a latero-lateral gastro-jejunal anastomosis instead of a termino-lateral anastomosis, as is carried out as described in the original procedure. The rationale for these changes is to try to reduce exposure of the gastric mucosa to biliopancreatic secretions because of their potentially carcinogenic effects with longer term exposure, which is the major criticism of the original technique. If we fix the jejunal loop to the gastric pouch some centimetres up to the gastro-jejunal anastomosis the biliopancreatic secretions have less possibility of coming into the gastric cavity (gravity force). Furthermore, if the anastomosis is latero-lateral this possibility is reduced even more. In addition, the intestinal loop reinforces the staple line against disruption, and also the gastric pouch against dilatation.<br>El Bypass Gástrico de Una Anastomosis se ha desarrollado a partir del Mini Bypass Gástrico descrito por Robert Rutledge. La modificación del procedimiento original consiste en hacer una anastomosis latero-lateral en lugar de termino-lateral como se hace en la técnica original. Este cambio intenta reducir la exposición de la mucosa gástrica a la secreción bilio-pancreática, evitando así el posible efecto carcinogénico de la exposición crónica que constituye la más importante crítica del procedimiento original. Al fijar el asa de yeyuno a la nueva bolsa gástrica unos centímetros por encima de la anastomosis gastro-yeyunal, la secreción bilio-pancreática tiene menos posibilidades de entrar en la cavidad gástrica (fuerza de gravedad). Al ser la anastomosis latero-lateral esta posibilidad se reduce aún más. Además, el asa de yeyuno refuerza la línea de grapas contra su disrupción y previene la posible dilatación de la bolsa gástrica.
