Facts On 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 usually conducted using a laparoscope. This is an instrument that makes it possible to enter the abdomen through minimal access. A silicon based band is placed on the upper section of the stomach such that it compresses the area and reduces the organ to a small pouch. Approximately one ounce of food can be held by the pouch after a single meal.

There are a number of side effects associated with this surgery. They include bleeding (usually minimal), vomiting, nausea and aversion to food. The compression force from the band can be increased or reduced to minimize the symptoms. This is can be achieved by injecting or withdrawing water from a plastic tubing attached to the band. When water is injected the compression increases and when it is withdrawn, it reduces.

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.

The ideal body mass index, BMI, of a potential candidate should be more than 40. For persons that are already suffering from conditions believed to be caused or aggravated by excessive weight, a lower BMI is usually considered. Examples of these conditions include sleep apnea, esophageal reflux disease, hypertension and diabetes among others. Research has shown that surgery helps reduce the severity of these conditions.

There are some situations in which these operations are deemed unsafe. In case one has hormonal imbalance (as is the case of hypothyroidism), the surgery is usually postponed until the condition has been treated. Other high risk situations include the presence of gastrointestinal diseases such as peptic ulcers, esophagitis and inflammatory bowel disease among others.

Typically, the surgery is done as a day case which means that one can be released from the hospital on the same day. In a few cases, one may be kept on the hospital for between 24 and 48 hours for observation. A liquid dies is recommended for the first two weeks after the operation so as to allow for proper healing of the stitched regions on the stomach (in the case of gastrectomy).
