Important Aspects Of 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 operations work by reducing the functional capacity of the stomach. The stomach tends to fill faster than before hence there is a reduction in the amount of food eaten. Most of the food that is consumed undergoes metabolism to produce energy and very little is converted to fat. With time, there is net weight loss. The fundamental difference between the two is the fact that while lap-band surgery is can be reversed while sleeve gastrectomy is permanent.

The lap band procedure is usually done using an instrument called a laparoscope. The exact procedure involves minimal access of the abdomen using three small incisions. A silicon band is usually placed on the upper region of the stomach where it causes compression. With the organ now converted into a small pouch, only a small amount of food can be held at any one time.

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 When water is injected into the tube the size reduces and when it is withdrawn it increases and symptoms abate.

In sleeve gastrectomy, surgical resection of the stomach helps to reduce it by as much as 80%. The resultant stomach takes the shape of a sleeve (hence the name). Due to the reduction in capacity there will be early satiety and generally a reduction in consumption of food. The other benefit of this transformation is the fact that transit time is greatly reduced and so is the absorption of nutrients.

Generally, surgical weight loss surgery is most beneficial in persons with a body mass index (BMI) of more than 40. In case they have weight related complications such as diabetes, hypertension, sleep apnea and gastro esophageal reflux disease, a lower BMI may be considered. Bariatric surgeries have been shown to reduce the symptoms associated with 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.

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.
