Bariatric surgeries are becoming a preferred mode of weight loss all over the world include New York City. The reasons behind this are the increase safety and effectiveness of these procedures. Three main types of weight loss surgeries are performed: gastric banding, gastric bypass and sleeve gastrectomy. Both similarities and difference exist among these techniques. Lap-band and laparoscopic sleeve gastrectomy are associated with better outcomes than the bypass procedure.
Surgical options for weight should only come in when all the other methods have been exhausted. The general recommendation is that conservative options should be tried out for at least 6 months. Dietary modification is one of the approaches that have been shown to be quite effective in achieving weight loss. One should strive to reduce their consumption of fats and carbohydrates and increase that of vegetables and fruits. Regular physical exercise also has a role to play.
The decision to undergo either lap band surgery or sleeve gastrectomy is made by the doctor in consultation with the patient. The choice is made after carefully considering the benefits of each of them. Both can be performed through the open technique or through laparoscopy. One of the major differences between the two is the fact that banding is reversible while gastrectomy is a permanent procedure.
When the open technique is to be used to perform banding, a large incision has to be made in the anterior abdominal region. Such will allow the surgeon to visualize the abdominal structures directly and can place the band around the stomach with ease. In the case of laparoscopy, the incisions that are needed are a lot smaller and the doctor has to rely on images projected on to a monitor to perform the procedure.
Gastrectomy involves reduction of stomach size by removing between 75 and 80% of the organ. The operation leaves behind a small tubular structure whose shape is like a sleeve thus the name of the procedure. Laparoscopic access to the abdominal cavity is the most preferred technique. Once the unwanted portion has been removed, the remaining part is stitched using staples or surgical sutures. With a significant reduction in capacity, the stomach can only hold a limited amount of food.
A number of complications may occur following these operations. Excessive bleeding, injury to internal organs and post-operative infections are among the most commonly encountered. In rare circumstances, the staples or stitches used during the operation may come off. Leakage of foods and acids may then ensue and cause chemical injury to other organs. Nausea and vomiting will be experienced if the squeeze of the band is too much.
Reduced stomach capacity translates into reduced intake of food. This is not only due to the smaller quantity of food that can be held at one time but also due to the associated early satiety. A reduction in the surface area of the stomach also reduces the amount of food absorbed. Weight loss begins to become evident within weeks or months depending on the magnitude of the problem.
There are a number of conditions that may increase the risk of these operations. Patients with hormonal imbalance (such as hyperthyroidism) and metabolic conditions (such as diabetes) need to have these problems solved first before they have the operation. Apart from the systemic conditions, diseases that affect the stomach may delay healing and lead to poor outcomes. Examples include inflammatory bowel disease and peptic ulcer disease. These too have to be managed beforehand.
