My brother is stage 4 Esophageal cancer-is unable to eat or swallow. Unfortunately he is in La Paz Mexico and his care is marginal at best. They finally inserted a feeding tube today. We (his family) will be cleaning and maintaining it. We don't know the best formula to give him-he hasn't had anything but IV fluids for the past week so his body needs nutrition just not sure what is best. And no there is not a doctor on hand to tell us.
