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).
If you have open surgery:
- The surgeon makes a large surgical cut in your belly to open the area.
- 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.
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:
- 3 to 5 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 for anesthesia and surgert in general include:
Risks for this surgery include:
- Damage to the intestine
- Leakage of stomach contents
- Long-term diarrhea
- Tear in the lining of nearby organs (mucosal perforation)
Before the Procedure
Tell your doctor or nurse:
- If you are or could be pregnant
- What medicines you are 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 doctor which drugs you should still take on the day of the surgery.
- If you smoke, try to stop. Ask your health care provider for help quitting.
On the day of your surgery:
- Follow your doctor's instructions about when to stop eating and drinking.
- Take the medicines your doctor 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.
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.
