Laparoscopic Gastric Bypass Procedure

Obesity is a common problem in the United States. In 2002, the Centers for Disease Control and Prevention reported that two-thirds of adult Americans are overweight. The treatment of obesity is very difficult, especially when the patient does not have a correctable endocrine problem. Low-calorie, low-fat balanced diets are usually recommended, along with exercise. "Crash" diets and diet drugs are usually discouraged.

What is morbid obesity?
Patients weighing more than 100 pounds over their ideal body weight or a calculation of the body mass index (BMI) greater than 35 to 40 are considered to be obese.(To calculate your BMI, multiply your weight by 705. Divide the result by your height in inches. Divide by your height again.) Massively obese persons have an increased risk of diabetes, hypertension, heart disease, hyperlipidemia, sleep apnea (temporary stopping of breathing during sleep), and osteoarthritis.

Your doctor will explain BMI in greater detail and carefully assess your need for surgery. You may be a candidate for laparoscopic gastric bypass procedure if attempts at restrictive diets and exercise have failed.

Will my insurance company cover this procedure?
In recent years, research has clearly shown that obese individuals have a shortened life span. Many insurance companies now recognize obesity as a substantial health risk and are paying for laparoscopic bypass procedure. To determine if your insurance company will cover this type of medical care, contact them and enquire about the following CPT codes: 43645 (Roux-en-Y gastric bypass); 43770 (adjustable gastric band); and 49320 and 43843 (sleeve gastrectomy), or speak with a financial counselor at Cleveland Clinic at (216) 445-1745.

How can I benefit from laparoscopic gastric bypass procedure?
The most important benefit you will experience is significant weight loss, which occurs during the first year following surgery. Significant weight loss can make medical problems such as diabetes, hypertension and coronary artery disease easier to treat or may eliminate a problem altogether. You will also benefit from the use of laparoscopy, which requires much smaller incisions than traditional abdominal surgery. Patients generally have less pain and scarring after surgery and recover more quickly. Laparoscopy also reduces your risk of developing hernias, which are more common after traditional abdominal surgery. Though gastric bypass procedure can be reversed, you should carefully consider all of the risks and benefits before electing to have this surgery.

What is involved before, during, and after surgery?

Before surgery:
Persons considered for surgery must be carefully evaluated. Studies are performed to assess the health of the patient’s cardiovascular, pulmonary, and endocrine systems. A psychological evaluation is considered essential by most physicians to determine a potential patient’s response to weight loss and change in body image and ability for permanent lifestyle change. Nutritional counseling is also a must before surgery.

During surgery:
Various laparoscopic (minimally invasive) surgical procedures have evolved in an effort to "shunt" or bypass a portion of the stomach. The procedure we perform at Cleveland Clinic are laparoscopic isolated gastric bypass, adjustable gastric band, and sleeve gastrectomy.

After surgery:
Most patients recover from surgery with no complications.
