Which of the following is a possible surgical treatment for pyloric stenosis?

Pyloroplasty
Fredet-Ramstedt pyloromyotomy
Gastric bypass
Fundoplication

The correct answer is: Fredet-Ramstedt pyloromyotomy

Pyloric stenosis is a condition characterized by the narrowing of the pylorus, the outlet of the stomach, which can lead to feeding difficulties and vomiting, particularly in infants. The primary surgical treatment for this condition is a procedure called pyloromyotomy. In the Fredet-Ramstedt pyloromyotomy, the surgeon makes an incision to divide the muscle fibers of the pylorus without incising the overlying mucosa, allowing for a wider passage from the stomach to the duodenum. This technique effectively alleviates the obstruction caused by the thickened pyloric muscle, enabling normal gastric emptying and relieving the symptoms associated with pyloric stenosis. Other procedures listed, such as pyloroplasty, are not typically used for pyloric stenosis. Pyloroplasty is intended for conditions that require easing gastric drainage but does not specifically address the hypertrophied muscle in pyloric stenosis. Gastric bypass and fundoplication are more complex procedures aimed at obesity and gastroesophageal reflux respectively, and do not serve as treatments for pyloric stenosis. Therefore, the Fredet-Ramstedt pyloromyotomy stands out as the most appropriate and effective surgical intervention for this specific condition.
