REFLUX - GERD
Gastrointestinal colonoscopy surgery is a treatment for diseases of the parts of the body involved in indigestion. This includes the esophagus, stomach, small intestine, large intestine, and rectum. It also includes the liver, gallbladder, and pancreas.
Below are gastrointestinal conditions that may be treated with surgery:
Gastroesophageal reflux disease (GERD) and Hiatus Hernia
What is gastroesophageal reflux?
Gastroesophageal refers to the stomach and esophagus. Reflux means to flow back or return. Therefore, gastroesophageal reflux is the return of the stomach’s contents back up into the esophagus.
In normal digestion, the lower esophageal sphincter (LES) opens to allow food to pass into the stomach and closes to prevent food and acidic stomach juices from flowing back into the esophagus. Gastroesophageal reflux occurs when the LES is weak or relaxes inappropriately, allowing the stomach’s contents to flow up into the esophagus.
The severity of GERD depends on LES dysfunction as well as the type and amount of fluid brought up from the stomach and the neutralising effect of saliva.
Hiatal hernia may weaken the LES and increase the risk for gastroesophageal reflux. Hiatal hernia occurs when the upper part of the stomach moves up into the chest through a small opening in the diaphragm (diaphragmatic hiatus). The diaphragm is the muscle separating the abdomen from the chest. Recent studies show that the opening in the diaphragm helps support the lower end of the esophagus. Many people with a hiatal hernia will not have problems with heartburn or reflux. But having a hiatal hernia may allow stomach contents to reflux more easily into the esophagus.
Coughing, vomiting, straining, or sudden physical exertion can cause increased pressure in the abdomen resulting in hiatal hernia. Obesity and pregnancy also contribute to this condition. Many otherwise healthy people age 50 and over have a small hiatal hernia. Although considered a condition of middle age, hiatal hernias affect people of all ages.
Hiatal hernias usually do not require treatment. However, treatment may be necessary if the hernia is in danger of becoming strangulated (twisted in a way that cuts off blood supply) or is complicated by severe GERD or esophagitis (inflammation of the esophagus). The doctor may perform surgery to reduce the size of the hernia or to prevent strangulation.

What other factors contribute to GERD?
Dietary and lifestyle choices may contribute to GERD. Certain foods and beverages, including chocolate, peppermint, fried or fatty foods, coffee or alcoholic beverages, may trigger reflux and heartburn. Studies show that cigarette smoking relaxes the LES. Obesity and pregnancy can also play a role in GERD symptoms.
What are the symptoms of heartburn?
Heartburn, also called acid indigestion, is the most common symptom of GERD and usually feels like a burning chest pain beginning behind the breastbone and moving upward to the neck and throat. Many people say it feels like food is coming back into the mouth leaving an acid or bitter taste.
The burning, pressure, or pain of heartburn can last as long as 2 hours and is often worse after eating. Lying down or bending over can also result in heartburn. Many people obtain relief by standing upright or by taking an antacid that clears acid out of the esophagus.
Heartburn pain is sometimes mistaken for the pain associated with heart disease or a heart attack, but there are differences. Exercise may aggravate pain resulting from heart disease, and rest may relieve the pain. Heartburn pain is less likely to be associated with physical activity. But you can’t tell the difference, so seek immediate medical help if you have any chest pain.
How common is heartburn and GERD?
More than 60 million American adults experience heartburn at least once a month, and more than 15 million adults suffer daily from heartburn. Many pregnant women experience daily heartburn. Recent studies show that GERD in infants and children is more common than previously recognised and may produce recurrent vomiting, coughing and other respiratory problems.
What is the treatment for GERD?
We recommend lifestyle and dietary changes for most people needing treatment for GERD. Treatment aims at decreasing the amount of reflux or reducing damage to the lining of the esophagus from refluxed materials.
Avoiding foods and beverages that can relax the LES is often recommended. These foods include chocolate, peppermint, fatty foods, caffeine and alcoholic beverages. Foods and beverages that can irritate a damaged esophageal lining such as citrus fruits and juices, tomato products and pepper should also be avoided if they cause symptoms.
Decreasing the size of portions at mealtime may also help control symptoms. Eating meals at least 2 to 3 hours before bedtime may lessen reflux by allowing the acid in the stomach to decrease and the stomach to empty partially. In addition, being overweight often worsens symptoms. Many overweight people find relief when they lose weight.
Cigarette smoking weakens the LES. Stopping smoking is important to reduce GERD symptoms.
Elevating the head of the bed on 6-inch blocks or sleeping on a specially designed wedge reduces heartburn by allowing gravity to minimise reflux of stomach contents into the esophagus. Do not use pillows to prop yourself up; that only increases pressure on the stomach.
Along with lifestyle and diet changes, we may recommend certain medications.
Antacids can help neutralise acid in the esophagus and stomach and stop heartburn. Many people find that antacids provide temporary or partial relief. An antacid combined with a foaming agent helps some people. These compounds are believed to form a foam barrier on top of the stomach that prevents acid reflux from occurring.
Long-term use of antacids, however, can result in side effects, including diarrhea, altered calcium metabolism (a change in the way the body breaks down and uses calcium) and buildup of magnesium in the body. Too much magnesium can be serious for patients with kidney disease.
For chronic reflux and heartburn, the doctor may recommend medications to reduce acid in the stomach. These medicines include H2 blockers, which inhibit acid secretion in the stomach. H2 blockers include: famotidine, nizatidine and ranitidine.
Another type of drug, the proton pump inhibitor (or acid pump), inhibits an enzyme (a protein in the acid-producing cells of the stomach) necessary for acid secretion. Some proton pump inhibitors include dexlansoprazole, esomeprazole, lansoprazole, omeprazole, pantoprazole and rabeprazole.
