What One Should Know About Lap-band And Laparoscopic Sleeve Gastrectomy

By Catherine Howard


The number of weight loss surgical procedures being done in New York has continued to increase tremendously. Part of the reason for this is the fact that the techniques that are employed have been greatly improved and the procedure is now not only safe but also very effective. Lap-band and laparoscopic sleeve gastrectomy are two of the most commonly performed bariatric operations. It is important that one first tries out lifestyle changes before turning to surgery for weight loss.

The two types of surgeries achieve their effect by reducing the size of the stomach. As a result, one is likely to experience early satiety and their food consumption is going to reduce. Most of what is eaten goes to energy provision with very little being stored in adipose tissues as fat. The net effect within subsequent weeks and months is weight loss. The main difference between sleeve gastrectomy and lap band surgery is that lap band surgery is reversible while gastrectomy is not.

Lap band surgery is typically performed laparoscopically. This involves entry into the abdomen through minimal access. Three small incisions (ports) are made in the anterior abdominal wall and used for the insertion of a camera and instruments. A silicon band is fixed to the upper stomach portion so as to cause compression. This converts the entire organ into a small pouch capable of holding just a small amount of food.

After the operation, one may suffer from a number of side effects that include minimal bleeding, aversion to food, nausea and vomiting. Reducing the compression force by the silicon band may help reduce the severity of some of the symptoms. This is made possible by injecting or drawing saline from a tube that is connected to the band. When water is injected into the tube the size reduces and when it is withdrawn it increases and symptoms abate.

Sleeve gastrectomy reduces the size of the stomach to between 20 and 25% of the original. The shape becomes tubular and closely resembles a sleeve. With a reduction in the capacity, the amount of food that one can eat also reduces markedly. In addition, there is a reduction in the transit time of food within the gut hence less absorption of nutrients.

Experts recommend that the ideal candidate should have a body mass index (BMI) of at least 40. However, if they have some conditions that may have been contributed or worsened by excess weight, then a lower value of BMI may be considered. The reason for this is that bariatric surgeries may help slow the progression of such conditions. Examples include sleep apnea, gastro esophageal reflux disease, diabetes and hypertension among others.

A number of high risk situations in which having the procedure is not recommended include. One of them is the presence of a hormonal abnormality such as that involving the thyroid hormone. The surgery has to be postponed in this case until the problem is treated. Other likely high risk conditions include esophagitis, inflammatory bowel disease and peptic ulcers among others.

The operation is typically conducted as a day procedure meaning that you can leave the hospital on the same day. In a number of cases, there may be a need to remain in hospital for a day or two for observation. Once you are discharged, the doctor will prescribe a liquid diet for at least two weeks. Ensure that you adopt a healthy lifestyle after the operation so as to get optimal results.
