PyloroplastyDefinition: Pyloric stenosis is a condition that causes projectile, nonbilious vomiting during the first 3 months of life. Pyloromyotomy is a surgical procedure that relieves the gastric outlet caused by pyloric stenosis, allowing the stomach contents to empty into the duodenum (small intestine).
Alternative Names: Pyloromyotomy; Pyloric stenosis repair
Description: While the patient is under general anesthesia (unconscious and pain-free), the surgeon performs the procedure using an open approach (through an incision around the belly button or in the right upper part or the belly), or a laparoscopic approach (using 3 small incisions and a camera called a laparoscope).
Indications: Pyloromyotomy is the only effective treatment for pyloric stenosis. Patients with this condition are frequently dehydrated and must receive intravenous fluids before going to surgery.
Risks: Risks for any anesthesia include the following: - Reactions to medications
- Problems breathing
Risks for any surgery include the following: Risks specific to this procedure: - Mucosal perforation
- Incomplete pyloromyotomy
Expectations after surgery: Children usually recover rapidly.
Convalescence: Patients can usually be started on breastmilk/formula feeds 2 hours after uncomplicated surgery. Some patients will vomit once or twice afterward, but most can go home within 24 hours.
