Pyloroplasty

Definition

Pyloroplasty is surgery to widen the opening of the end of the pylorus, which is found in the lower portion of the stomach, so that stomach contents can empty into the duodenum (small intestine).

See: Pyloric stenosis

Alternative Names

Description

The surgery is done while the patient is under general anesthesia (unconscious and pain-free). The surgeon makes a cut around the belly button or in the right upper part of the belly. If the surgery is done laparoscopically, three smaller cuts are used. The end of the pylorus is repaired, so that muscles in the area can relax and the stomach can empty its contents.

Why the Procedure is Performed

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.

Risks

Risks for any anesthesia include the following:

• Reactions to medications
• Problems breathing

• Bleeding
• Infection

Risks specific to this procedure:

• Tear in the lining of surrounding organs (mucosal perforation)
• Long-term diarrhea
• Malnutrition

Outlook (Prognosis)

Most patients make a complete and quick recovery.

Recovery

After surgery, the health care team will monitor the patient's breathing, blood pressure, temperature, and heart rate. Some patients will vomit once or twice after surgery, but most can go home within 24 hours.
