Gastroesophageal Reflux Disease: Practice Essentials, Background, Anatomy

Symptoms of acid reflux include heartburn, regurgitation of bitter acid into the throat, bitter taste in mouth, ches pain, dry cough, hoarseness, feeling of tightness in the throat, and wheezing. Narrowing of the esophagus (esophageal stricture). Damage to the lower esophagus from stomach acid causes scar tissue to form.

Don’t wear tight clothing around your abdomen, and avoid tobacco and alcohol. An open sore in the esophagus (esophageal ulcer). Stomach acid can wear away tissue in the esophagus, causing an open sore to form. An esophageal ulcer can bleed, cause pain and make swallowing difficult. If the sphincter relaxes abnormally or weakens, stomach acid can flow back up into your esophagus.

Thus, no one would deny the well-established condition of childhood atopic asthma associated with allergy to cats, house and dogs dust mites, and due to a familial hyper-responsiveness to aero allergens. However, this paradigm of asthma has now been extended into what was called intrinsic asthma (which ironically is literally intrinsic) where no allergen can be found. Similarly pulmonary fibrosis undoubtedly can be caused by exposure to external factors, such as asbestos. Idiopathic pulmonary fibrosis however has resisted all attempts to find the external stimulus and, until recently, clinicians have steadfastly refused to accept it as part of an intrinsic process.

GERD can irritate the food cause and pipe heartburn and other symptoms. The most common symptom of gastroesophageal reflux disease (GERD) is persistent heartburn, called acid reflux also. GERD happens when your lower esophageal sphincter becomes weak or relaxes when it shouldn’t. Gastroesophageal reflux (GER) happens when your stomach contents come back up into your esophagus causing heartburn (also called acid reflux).

The dietary restrictions are slowly lifted after several weeks and the patient progresses through a soft and/or post-Nissen diet. Many surgeons recommend that their patients only take crushed or liquid medications for several weeks after surgery. Surgery is a last resort for people with GERD and is rarely needed in healthy teens. Lots of people who have GERD notice their heartburn is worse after eating.

Proton pump inhibitors block acid production and may be effective also. Everyone has experienced gastroesophageal reflux.

Barrett esophagus is thought to be caused by the chronic reflux of gastric juice into the esophagus. It is defined by metaplastic conversion of the normal distal squamous esophageal epithelium to columnar epithelium. Histologic examination of esophageal biopsy specimens is required to make the diagnosis. Varying degrees of dysplasia may be found on histologic examination. The mechanism by which a high BMI increases esophageal acid exposure is not completely understood.

Non-acid reflux is a particular problem in pediatrics because children are fed more frequently than adults and the majority of non-acid reflux occurs in the period after mealtime (post-prandial) when stomach contents are neutralized. Additionally, there are many children that are continuously fed through gastrostomy tubes such that the pH of the stomach is neutral for the majority of the day.

Transthoracic and transabdominal fundoplications are performed for gastroesophageal reflux disease, including partial (anterior or posterior) and circumferential wraps. Open and laparoscopic techniques may be used. Upper gastrointestinal contrast-enhanced studies are the initial radiologic procedure of choice in the workup gastroesophageal reflux disease. Plain chest radiographic findings are not useful in the evaluation of this condition, but they are helpful in assessing the pulmonary status and basic anatomy. Chest images may demonstrate a large hiatal hernia also, but small hernias can be missed easily.

The most common symptom of GERD is heartburn. This is an uncomfortable burning sensation felt in the middle of the upper abdomen and/or lower chest.

In many of these full cases, appropriate testing and multidisciplinary evaluation with a surgeon, a gastroenterologist, an otolaryngologist (ear, nose, and throat specialist), and a pulmonologist (lung and respiratory specialist) is important in confirming the diagnosis and ruling out other potential causes. The outcomes after laparoscopic antireflux surgery are generally excellent. In both short-term (1-5 years) and long-term studies (5-10 years), the vast majority of patients report effective symptom reduction, a high level of satisfaction, and an improved quality of life after having the surgery. Nearly all patients are taken off of reflux medication after surgery.

In the validation of this questionnaire, heartburn was found to be the least-associated symptom, reinforcing the importance of the non-acid nature of this phenomenon [6]. Although the laparoscopic fundoplication is the current standard of surgical care, there is an evolving array of exciting new endoscopic, incisionless treatments for GERD under evaluation. The newest therapy is the transoral incisionless fundoplication (TIF).

Normally, a ring of muscle at the bottom of the esophagus, called the lower esophageal sphincter, prevents reflux (or backing up) of acid. The prognosis for acid reflux (GERD) is good in mild to moderate cases. Chronic cases often respond to prescription drugs, and severe cases might require surgery to avoid serious complications.
