Pyloroplasty is surgery to widen the opening in the lower part of the stomach (pylorus) so that stomach contents can empty into the small intestine (duodenum).
The pylorus is a thick, muscular area. When it thickens, food cannot pass through.
The surgery is done while you are under general anesthesia (asleep and pain-free).
The surgeon makes a cut in the belly area. If the surgery is done using a laparoscope, three smaller cuts are made instead.
The surgeon cuts through some of the thickened muscle so it becomes wider.
The cut is then closed in a way that keeps the pylorus open. This allows the stomach to empty.
The surgery usually takes 1 - 2 hours.
Why the Procedure Is Performed
Pyloroplasty is used to treat complications in patients with peptic ulcers or other stomach problems that cause a blockage of the stomach opening.
Risks of anesthesia include:
- Reactions to medications
- Problems breathing
Risks of any surgery include:
Risks of this procedure:
- Damage to the intestine
- Leakage of stomach contents
- Long-term diarrhea
- Tear in the lining of nearby organs (mucosal perforation)
After the Procedure
Most patients recover quickly and completely. The average hospital stay is 2 - 3 days. Most patients can slowly begin 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.
