Gastric

The dynamic gastric model (DGM) was invented and designed by Dr. Martin Wickham and Dr. Richard Faulks from the United Kingdom. Even though the model is only half the size of the human digestive system, it can be used to investigate the effects of diet, drugs, alcohol and other factors on digestion. The figure is made of plastic and metal and is composed in two parts. The upper section is a funnel and a cylinder shaped container where food, enzyme, and gastric acid are mixed. After the hydration

Gastric acid production and secretion Gastric acid secretion is said to be a complex process regulated by hormonal and neural pathways (Ceglia et al. 2008). This paper would try to decipher the pathophysiology of gastric acid secretion and explain the changes process in different types of disorders such as gastritis, peptic ulcer disease, and gastroesophageal reflux disease. To begin talking about acid production and secretion, we have first to consider talking about the physiology of the stomach

Other than mortality, survival analysis can be used for those patients having gastric bypass surgery. Many advertisements are geared toward the obese patients in my area, much weight loss clinical and more surgeons are performing gastric bypass surgery. We have designated an entire unit for gastric bypass patients. Survival is said to improve in patients who have surgery those who don’t (Seppa, 2015) Studies also at the 10 year mark after surgery the death rate was 23.9 percent among thse who didn’t

According to Huether & McCance (2012) gastric secretions is stimulated by eating (gastric distention), by the hormone gastrin, paracrine pathways (histamine, ghrelin, somatostatin), by the neurotransmitter acetylcholine and chemicals (ethanol, coffee, protein). The stomach secretes large volumes of gastric juices or gastric including mucous, acid, enzymes, hormones, intrinsic factor, and gastroferrin. Intrinsic factor is necessary for the intestinal absorption of vitamin B12 and gastroferrin facilitates

1. Roux-en-Y gastric bypass is a special procedure used to treat morbid obesity. Describe in detail the Roux-en-Y procedure. The Roux-en-Y procedure is a laparoscopic form of gastric surgery that uses trocars to manipulate the stomach. The patient must be positioned supine with their arms extended outward or in the lithotomy position. This is dependent on where the trocars are positioned. The surgeon uses monitors to see inside the abdominal cavity and places the trocars a fist length away from

Gastric cancer Cancer is a disease that is caused by the growth of abnormal cells in a particular part or location in a person’s body. Since cancer is a build up of cells in one spot in your body, the cells has nowhere else to go, and in that case it could cause people to get a tumor. cancer is not contagious most of them are curable but if they are not treated right or at all the disease could spread to other organs near by or can be fatal. Gastric cancer or another name for it is stomach cancer

Aspiration of gastric contents is a major cause of morbidity and mortality related to anesthesia. According to the NAP4 report, aspiration accounts for 50% of allanesthesia-related deaths1. Aspiration pneumonia, sepsis and prolonged ICU admission are common among survivors. A Swedish study on 185 385 general anaesthetics reported an aspiration rate of 1 in 2131 patients, and four fatalities related directly or indirectly to gastric content aspiration into the lungs 2. While the overall incidence

Gastric Sleeve Vs Gastric Bypass : What is the Difference and what’s best option for me? If you are struggling to lose weight and you’re tired of the endless dieting, commercial weight-loss programs (magic pills) and all the other usual methods; maybe it is time you considered weight loss surgery. Your health will thank you. Because of their success rates in aiding weight-loss and their relative simplicity, most obese patients who consider undergoing bariatric surgery as a treatment for their obesity 

The number of gastric bypass surgeries has been increased in the last few years and it is considered the ‘‘gold standard’’ of bariatric operations. Bariatric operation or weight reduction surgery is recommended mainly for people whose BMI exceeds 40 kg/m2 as reported by the National Institutes of Health Consensus Development Program, or for those whose BMI is between 35 – 40 40 kg/m2 and who are have life-threatening complications such as cardiac problems (Franco et al., 2011). On the one hand,

Risk of developing gastric cancer in long term PPI users with prior history of GERD. Introduction: Proton pump inhibitors (PPIs) are commonly used in treatment for many conditions of the stomach, esophagus, and duodenum like gastroesophageal reflux disease (GERD), peptic ulcers and as prophylaxis of gastritis caused by many other widely used medications. PPIs are being used on long term basis and thus it is important to know the adverse effects as part of public health. Several epidemiological studies
