Pyloroplasty is a surgical procedure to widen the opening in the lower part of the stomach (pylorus) so that the stomach contents can empty into the small intestine (duodenum).

The pylorus is a thick, muscular area. When it thickens, food is not able to pass through.

The surgery is done while you are under general anesthesia (asleep and pain-free). The surgeon makes a cut around the belly button or in the upper right part of the belly. If the surgery is done laparoscopically, three smaller cuts are used.

The surgery involves cutting through some of the thickened muscle to relieve the narrowing (stenosis). The cut through the muscle is then closed horizontally to keep the pylorus open and allow the stomach to empty.

The surgery usually takes 1 - 2 hours.

Pyloric stenosis is caused by a thickened pylorus muscle. It is usually found in infants.

Pyloroplasty is the only effective treatment for pyloric stenosis. It may also be used to treat certain patients with peptic ulcers or other types of gastric disease that cause a blockage of the stomach opening.

Risks of anesthesia include the following:

• Reactions to medications
• Problems breathing

Risks of any operation include the following:

• Bleeding
• Infection

Risks of this procedure:

• Damage to the intestine
• Hernia
• Leakage of stomach contents
• Long-term diarrhea
• Malnutrition
• Tear in the lining of surrounding organs (mucosal perforation)

Most patients make a complete and quick recovery. The average hospital stay is 2 - 3 days. Most patients can gradually return to eating a regular diet in a few weeks.

After surgery, the health care team will monitor your breathing, blood pressure, temperature, and heart rate. Most patients can go home within 24 hours.

The results after pyloroplasty are excellent.
