Barrett's esophagus

Barrett’s esophagus is a complication in the esophagus from a reflux disease predisposing patients to esophageal adenocarcinoma. Esophageal adenocarcinoma is a tumor in the esophagus that has increased up more than 7-fold over the past few decades. Since there has been such a significant increase in esophageal adenocarcinoma, the topic of endoscopic screening and surveillance for GERD and Barrett’s esophagus is being heavily debated. Barrett’s esophagus is a result of chronic gastro-esophageal reflux disease, also known as GERD. GERD is a condition that occurs when a backflow of stomach contents, such as acidic fluid, flows back up through the esophagus. Esophageal complications from GERD lead to: reflux esophagitis, Barrett’s esophagus, and…

salivary glands, pharynx, the esophagus, the stomach, and duodenum. Each of these structures assists in the digestive functions of the body. The oral cavity is where mechanical digestion begins. Salivary glands secrete saliva to create a bolus. The bolus is then swallowed, moving through the pharynx to the stomach. In the stomach the bolus is mixed with digestive enzymes, acid, and mucin to create chyme. The chyme then moves from the stomach to the duodenum. It then makes its way through…

The letters GERD stand for gastro esophageal reflux disease (GERD). Basically it’s any disease caused by reflux of stomach of gastric contents into the esophagus. The classic symptom is heartburn. After eats one eats a few minutes to an hour they develop a burning sensation in their upper abdomen this burning could go all the way up behind the breast bone and into the throat, may have complaints of coughing or wheezing. They might get up at night with these symptoms. They may have swallowing…

Description and Prevalence Esophagus is part of the gastrointestinal (GI) system located in the upper body, posterior to the trachea (Huether and McCance, 2012). The esophagus consists of four layers (from outermost to innermost layer): adventitia, musculairis propria, submucosa and mucosa. The submucosa and the mucosa layers are very important because they are the common sites for cancer development. The submucosa layer contains gland cells that produce mucus for lubrication and aiding the…

I have chosen to write about gastroesophageal reflux disease which is also known as GERD. This disease is common in the United States and study has shown that there are over three million cases every year (MayoClinic). Gastroesophageal refers to the stomach and reflux means to return or back flow. The return of the stomachs contents back up into the esophagus which is why it's called gastroesophageal reflux. GERD is located at the end of the esophagus where it becomes inflamed. The inflammation…

Slow or absent esophageal peristalsis may not carry the bolus through the esophagus in an efficient and complete manner, causing discomfort or pain in the chest and leaving residue on the esophageal walls that may result in infection. In some patients, the lower esophageal sphincter does not sufficiently relax to allow the food in the esophagus to flow into the stomach, resulting in achalasia. Gastroenterologists are the medical professionals who treat esophageal…

Propels food along the digestive tract, responsible for contractions of GI tract, regulates mobility of GI tract. The muscularis externa of the stomach is modified because other muscularis externa is composed of two layers: the inner circular layer and the outer longitudinal layer. However, the muscularis externa of the stomach contains a third innermost oblique layer. This third innermost oblique layer relates to the function of the stomach because it is the smooth muscle that is responsible…

Once I tested out on the mouth, I then had to cut open the body cavity by first cutting a straight line that started just cranial to the hairs on the chin of my pig and ended cranial to the upper limbs of the pig. I then used my scalpel to cut a horizontal cut from the initial incision and pulled the skin and muscle away from the internal structures that I was required to locate in the neck. The internal structures that I had to locate in the neck were the hyoid apparatus, larynx, thyroid gland,…

GERD: Gastroesophageal Reflux Disease is most commonly known as “heartburn”. It refers to the back flow of gastric or duodenal contents or both into the esophagus and past the lower esophageal sphincter, without associated belching or vomiting. The reflux of gastric contents causes acute epigastric pain, usually after a meal. Common causes are: food, alcohol, or cigarettes, hiatal hernia, increased abdominal pressure (such as with obesity or pregnancy), medications, nasogastric intubation for…

of the stomach are brought back up the esophagus and can lead to a variety of symptoms and discomfort that can be mild to severe (1). It is also something that everyone has experienced to some degree. Anytime someone burps, has an acid taste in their mouth, or heartburn, he or she is experiencing symptoms of Gastroesophageal Reflux Disease. There is no reason to be concerned unless these symptoms begin happening more frequently, as often as daily (2). In this case, there are several…
