Nissen Fundoplication (reversal)
Is it possible for surgery to be performed to un-do a Nissen Fundoplication?
Yes, although it is rarely done. The reason to re-explore a child who is post-Nissen is usually that the Nissen has slipped above the diaphragm, the most significant of which is a condition called para-esophageal herniation. This can be life-threatening. The other most common reason is that the Nissen no longer is working, has broken down, and requires repair. To re-operate to "un-do" a Nissen suggests that it wasn't necessary in the first place, or it was done incorrectly and needs correction.
