antireflux procedure
Surgical intervention designed to prevent gastroesophageal reflux by reinforcing the lower esophageal sphincter.
Full Definition
A surgical procedure aimed at treating gastroesophageal reflux disease by creating or enhancing a competent antireflux mechanism at the gastroesophageal junction. Common techniques include Nissen fundoplication, Toupet fundoplication, and Thal fundoplication, each involving wrapping portions of the gastric fundus around the distal esophagus. In pediatric patients, these procedures are often performed laparoscopically and may be combined with other interventions such as gastrostomy tube placement. Indications include medication-refractory reflux, aspiration pneumonia, failure to thrive, or severe esophagitis. Long-term outcomes are generally favorable, though some patients may experience gas bloat syndrome or recurrent reflux.
Usage
