Treatment and Cure of Pyloric Stenosis
The treatment consist in correction of hypochloremic alkalosis and state of dehydration and performing a Fredet-Ramstedt modified pyloromyotomy. Post-operative management consist of: 50% will have one to several episodes of vomiting, usually can feed and go home in 24-36 hours, initial feeds start 8-12 hours after surgery. Treatment for pyloric stenosis involves surgery to split the overdeveloped muscles of the pylorus is the treatment for this disorder. Rehydration with intravenous fluids usually takes place prior to surgery.
Pyloric stenosis should not recur after a complete pyloromyotomy. If your baby continues to display symptoms weeks after the surgery, it may suggest another medical problem, such as inflammation of the stomach (gastritis) or GERD - or it could indicate that the initial pyloromyotomy was incomplete.
