Q

What is the Difference between a HIGHLY SELECTIVE VAGOTOMY compared to a TRUNCAL VAGOTOMY ?

A

In a Highly Selective Vagotomy the Nerve of Latarjet is left intact- allowing gastric emptying but also reducing stomach acid production

In a TRUNCAL VAGOTOMY the main trunk of the vagus nerve is denervated, impairing gastric emptying and motility
