Can pyloric stenosis return?

Dr. Charles Breaux

Usually not: Hypertrophic pyloric stenosis (HPS) in a young baby is treated with an operation called a pyloromyotomy. The hypertrophic circular pyloric muscle fibers are split to open the pylorus & allow the stomach to empty. If done well & thoroughly, HPS should not return. One occasionally hears of a case of recurrent HPS, but often, when looked at closely, it was an inadequate pyloromyotomy to begin with.

Rare: With a good o peration no. If operation does not completely separate all the pylorus muscle fibers then there can be residual symptoms.
Dr. Gerald Mandell
Nuclear Medicine 53 years experience
Very rare: Recurrent pyloric stenosis is extremely rare, 0.07% in one study. Some believe related to incomplete surgery of pyloric muscle I have seen it occur extremely rarely with very experienced pediatric surgeon.

What is pyloric stenosis?

Dr. Charles Breaux
Pediatric Surgery 40 years experience
Stomach exit blockag: In a baby with hypertrophic pyloric stenosis (HPS), the circular pyloric muscle fibers which regulate the emptying of the stomach become swollen ("muscle-bound") usually between 2 and 8 weeks' age. The pyloric channel becomes blocked, and fluid cannot exit the stomach. The baby has progressive projectile nonbilious vomiting which can cause dehydration and weight loss if uncorrected.
