Gastric Band Surgery

A gastric band is an inflatable silicone device that a surgeon places around the top portion of the stomach, via gastric band surgery, in order to treat obesity. Gastric band surgery is an example of bariatric surgery designed for obese patients with a body mass index (BMI) of 40 or greater, or between 35 to 40 in cases of patients with certain co-morbidities that are known to improve with weight loss, such as sleep apnea, diabetes, osteoarthritis, high blood pressure or metabolic syndrome, among others. Gastric banding is the least invasive surgery of all bariatric surgeries. Gastric banding using laparoscopic surgery usually results in a shorter hospital stay, faster recovery, smaller scars, and less pain than open surgical procedures. The patient can continue to absorb nutrients from food normally. Gastric bands are made entirely of biocompatible materials, so they can stay in the body without causing harm. However, not all patients are eligible for laparoscopy. Patients who are extremely obese, who have had previous abdominal surgery or have complicating medical problems may require a more open surgery approach. The surgeon creates a small incision near the belly button and pumps carbon dioxide into the abdomen to create a workspace. Then the surgeon inserts a small laparoscopic camera through the incision into the abdomen. The camera sends a picture of the stomach and abdominal cavity to a video monitor. It gives the surgeon a good view of the key structures in the abdominal cavity. The surgeon makes more small incisions in the abdomen. The surgeon watches the video monitor and works through these small incisions using instruments with long handles to complete the procedure. The surgeon creates a small, circular tunnel behind the stomach, inserts the gastric band through the tunnel and locks the band around the stomach. Clinical studies of laparoscopic bariatric surgery patients found that they felt better, spent more time doing recreational and physical activities, benefited from enhanced productivity and economic opportunities and had more self-confidence than they did before surgery. The placement of the band creates a small pouch, or stoma, at the top of the stomach. This pouch holds approximately one half cup of food. A typical stomach holds about six cups of food. The pouch fills with food quickly, and the band slows the passage of food from the pouch to the lower part of the stomach, causing the sensation of being full. As the upper part of the stomach registers as full, the message to the brain is that the entire stomach is full, and this sensation helps a person to be hungry less often, feel full more quickly and for a longer period, eat smaller portions, and lose weight over time. As patients lose weight, their bands will need adjustments, or "fills," to ensure comfort and effectiveness. The surgeon can adjust the gastric band by introducing a saline solution into a small access port just under the skin. There are many port designs and a surgeon may place them in varying positions, but they always connect to the muscle wall in and around the diaphragm via sutures or staples.

Personalized Medicine

Personalized medicine is a medical model emphasizing the systematic use of information about an individual patient to select or optimize that patient's preventative and therapeutic care. Personalized medicine is the products and services that leverage the science of genomics and proteomics and capitalize on the trends toward wellness and consumerism to enable tailored approaches to prevention and care. Over the past century, medical care has centered on standards of care based on epidemiological studies of large cohorts. Personalized medicine seeks to provide an objective basis for consideration of such individual differences. Traditionally, personalized medicine has been limited to the consideration of a patient's family history, social circumstances, environment, and behaviors in tailoring individual care. Personalized medicine uses new methods of molecular analysis to manage a patient’s disease or predisposition toward a disease. It aims to achieve optimal medical outcomes by helping physicians and patients choose the disease management approaches likely to work best in the context of a patient’s genetic and environmental profile. Such approaches may include genetic screening programs that more precisely diagnose diseases and their sub-types, or help physicians select the type and dose of medication best suited to a certain group of patients. Personalized medicine is an extension of traditional approaches to understanding and treating illness. Since the beginning of the study of medicine, physicians have employed evidence found through observation to make a diagnosis or to prescribe treatment. In the modern concept of personalized medicine, the tools provided to the physician are more precise, probing not just the obvious, such as a tumor on a mammogram or cells under a microscope, but the very molecular makeup of each patient. Looking at the patient on this level helps the physician get a profile of the patient’s genetic distinction, or mapping. By investigating this genetic mapping, medical professionals are then able to profile patients, and use the found information to plan a course of treatment that is much more in step with the way their body works. Genomic medicine and personalized medicine use genetic information to prevent or treat disease in adults or their children. Having a genetic map or a profile of a patient’s genetic variation can then guide the selection of drugs or treatment processes. This can minimize side effects or to create a strategy for a more successful outcome from the medical treatment. Helping the physician cover all the bases is imperative. Genetic mapping can also indicate the propensity to contract certain diseases before the patient actually shows recognizable symptoms, allowing the physician and patient to put together a plan for observation and prevention. Personalized medicine, when coupled with personal pharmacogenetics, is a unique approach that may be well suited for the health challenges we face in the new millennium. Although the medical and scientific communities, through research and discovery, got the upper hand over many of the diseases we have encountered since the advent of advanced medicine, many diseases that are more complicated. Diseases like diabetes, heart disease, cancer, and Alzheimer’s are caused by a combination of genetic and other factors. Coupled with the fact that they tend to be chronic, they place a significant burden on not only the patient, but on the healthcare system as a whole. Personalized medicine aims to provide the tools and knowledge to fight chronic diseases and treat them more effectively than ever before. Genetic profiles can help physicians to better discern subgroups of patients with various forms of cancer, in addition to other complex diseases, helping to guide doctors with accurate forms of predictive medicine and preventative medicine. With personalized medicine, the physician is intending to select the best treatment protocol or even, in many cases, avoid passing the expense and risks of unnecessary medical treatments on to the patient altogether. In addition, personalized medicine, when used correctly, aims to guide tests that detect variation in the way individual patients metabolize various pharmaceuticals. Personalized medicine is working to help determine the right dose for a patient, helping to avoid hazards based on familial history, environmental influences, and genetic variation.
