I have severe acid reflux and after years of conventional treatment that has failed. I have been booked in for a nerve block. I wanted to know what is the difference between a cephalic and splanchnic nerve block? Is there a difference? which is safer? I read in a journal that cephalic nerve block can lead to diarrhoea and there have been few reported deaths. It seems to be one of the risks involved?
Is this the case? Does the same risk exist with the splanchnic nerve block?
