What kind of doctor provides Surgical Gastroenterology?
A surgeon who operates on the belly and digestive system does these operations. A gastroenterologist, a doctor who treats digestive diseases, often helps find the problem. This doctor may refer you. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What it is
Surgical gastroenterology is a field of care. It is not one operation. Three common operations are described here. They are abdominal exploration, appendectomy, and open gallbladder removal. Other belly operations are not covered.
Abdominal exploration is surgery to look at the organs and structures in your belly. These include the appendix, gallbladder, intestines, liver, pancreas, and stomach. An appendectomy is surgery to remove the appendix. Open gallbladder removal is surgery to take out the gallbladder. It uses a large cut in your belly.
Why a doctor might recommend it
Doctors may recommend abdominal exploration when x-rays and CT scans have not given an accurate diagnosis. It can help find problems. Examples are a blocked intestine, a hole in the intestine, and gallstones.
An appendectomy is done for appendicitis. This is a swollen or infected appendix. An appendix with a hole in it can leak. It can infect the whole belly area. This can be life threatening. Many cases of appendicitis are treated with antibiotics only, without an operation. Ask your provider if you are a candidate for this.
You may need open gallbladder removal for pain or other symptoms from gallstones. You may also need it if your gallbladder is not working normally.
How to prepare
These steps may help you get ready.
- If you smoke, cut back or quit. Smoking can slow healing.
- Tell your surgeon if you are or could be pregnant. Also tell your surgeon about any medicines, supplements, or herbs you take.
- You may be asked to pause blood thinners. These are medicines that keep your blood from clotting. Ask your surgeon which medicines you should still take on the day of surgery.
- Follow the instructions about when to stop eating and drinking.
What happens during it
Abdominal exploration is done under general anesthesia. This means you are asleep and feel no pain. Your surgeon cuts into the belly. Then the surgeon looks at the organs. If possible, laparoscopy is done instead. It uses a tiny camera placed inside the belly.
An appendectomy uses general or spinal anesthesia. The surgeon may make a small cut in the lower right side of your belly. The appendix can also come out through small cuts. A camera is used for this.
For open gallbladder removal, the surgeon makes a cut in the upper right part of your belly, just below your ribs. The surgeon separates the gallbladder from the liver and lifts it out. The surgery takes about 1 to 2 hours.
Recovery
After abdominal exploration, you should be able to eat and drink normally about 1 to 3 days after surgery. Complete recovery usually takes about 4 to 6 weeks. Most people leave the hospital 1 to 2 days after an appendectomy. After open gallbladder removal, you may stay 2 or more days. Healing from the open cut takes several weeks.
Call 911 or go to the emergency room if you have trouble breathing, chest pain or discomfort lasting two minutes or more, fainting, severe belly pain or pressure, or bleeding that will not stop.
Risks and side effects
Any surgery and anesthesia can cause reactions to medicines. They can also cause breathing problems, bleeding, blood clots, and infection. Abdominal exploration can also damage organs in the belly. Gallbladder surgery can injure the common bile duct. It can also injure the small or large intestine.
Who performs it
A surgeon does these operations.
Common questions
What is the difference between open surgery and laparoscopy?
Open surgery uses a larger cut. Laparoscopy uses small cuts and a tiny camera. For gallbladder removal, laparoscopy is the most common way. Open surgery is used when laparoscopic surgery cannot be done safely.
Does appendicitis always need surgery?
No. Many cases of appendicitis are treated with antibiotics only, without an operation. Ask your provider if you are a candidate for this.
How does a direct primary care or concierge doctor fit in?
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either one can check belly symptoms and order tests. They can refer you to a surgeon and follow up after surgery. They do not do the operation.
