Peptic ulcer – pyloroplasty; PUD – pyloroplasty; Pyloric obstruction – pyloroplasty

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.

Description

The surgery is done while you are under general anesthesia (asleep and pain-free).

If you have open surgery, the surgeon:

Makes a large surgical cut in your belly to open the area.
Cuts through some of the thickened muscle so it becomes wider.
Closes the cut in a way that keeps the pylorus open. This allows the stomach to empty.

Surgeons can also do this surgery using a laparoscope. A laparoscope is a tiny camera that is inserted into your belly through a small cut. Video from the camera will appear on a monitor in the operating room. The surgeon views the monitor to do the surgery. During the surgery:

Three to five small cuts are made in your belly. The camera and other small tools will be inserted through these cuts.
Your belly will be filled with gas to allow the surgeon to see the area and perform the surgery with more room to work.
The pylorus is operated on as described above.

Why the Procedure Is Performed

Pyloroplasty is used to treat complications in people with peptic ulcers or other stomach problems that cause a blockage of the stomach opening.

Risks

Risks for anesthesia and surgery in general are:

Reactions to medications or breathing problems
Bleeding , blood clots , or infection

Risks for this surgery include:

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

Before the Procedure

Tell your surgeon:

If you are or could be pregnant
What medicines you’re taking, including medicines, supplements, or herbs you bought without a prescription

During the days before your surgery:

You may be asked to stop taking medicines that make it hard for your blood to clot. Some of these are aspirin, ibuprofen (Advil, Motrin), vitamin E, warfarin (Coumadin), and clopidogrel (Plavix).
Ask your surgeon which drugs you should still take on the day of the surgery.
If you smoke, try to stop. Ask your surgeon for help quitting.

On the day of your surgery:

Follow instructions about not eating and drinking.
Take the medicines your surgeon told you to take with a small sip of water.
Arrive at the hospital on time.

After the Procedure

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

Outlook (Prognosis)

Most people recover quickly and completely. The average hospital stay is 2 to 3 days. Most people can slowly begin a regular diet in a few weeks.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Questions to ask

Which medicines are safe for my age, pregnancy status, allergy, kidney/liver/stomach condition, and current medicines?

Emergency warning signs such as chest pain, severe breathing difficulty, sudden weakness, confusion, severe dehydration, major injury, or loss of bladder/bowel control need urgent medical care. Do not wait for online information.

Go to emergency care if you notice:

Severe or rapidly worsening symptoms
