Recurrent pyloric stenosis and definitive operative management with repeat pyloromyotomy

Successful Treatment of Recurrent Pyloric Stenosis Using Balloon Dilation

“…Currently, repeat pyloromyotomy remains the preferred treatment option for recurrent pyloric stenosis (3,5). However, balloon dilation is an alternate option, although frequently discouraged due to unreliable results, a perceived need for multiple dilations, and concern for possible complications such as perforation and bleeding, especially with severe stenoses (4)(5)(6)(7)(8). Previous reports have shown variable results, leading most clinicians to recommend repeat pyloromyotomy for recurrent pyloric stenosis.…”

“…An incomplete pyloromyotomy occurs with a reported incidence of around 4%. However, recurrent pyloric stenosis is extremely rare ( 5 , 6 ). As a result, the pathophysiology is not well understood, with some authors arguing it results from an ongoing process driving pyloric hypertrophy continuing after initial pyloromyotomy ( 5 , 6 ).…”

“…However, recurrent pyloric stenosis is extremely rare ( 5 , 6 ). As a result, the pathophysiology is not well understood, with some authors arguing it results from an ongoing process driving pyloric hypertrophy continuing after initial pyloromyotomy ( 5 , 6 ). Criteria for recurrent pyloric stenosis are defined by complete resolution of symptoms for at least 3 weeks, subsequent weight gain postsurgery, and evidence of restenosis with imaging or operative confirmation ( 3 ).…”
