THE STORY OF WEIGHT LOSS SURGERY
Gastric Bypass History and Development
Weight loss surgery was introduced in the United States in the 1960's. The gastric bypass was based on the weight loss observed among patients undergoing partial stomach removal for ulcers. Over several decades, the gastric bypass has been modified into its current form, using a Roux-en-Y limb of intestine (RYGBP). Because the bypassed portion of intestine is where the majority of calcium and iron absorption takes place, anemia and osteoporosis are the most common long-term complications of the RYGBP, lifelong mineral supplementation is mandatory.
Other clinically important deficiencies that may occur include: Vitamin B 1 (thiamine) and Vitamin B 12 deficiencies. Lifelong follow-up with a bariatric program and daily multi-vitamins are strongly recommended to prevent nutritional complications. Although we are seeing a rapid increase in people electing to have lap band surgery, gastric bypass surgery remains the most common form of weight loss surgery performed in the United States today.
Development of the Lap Band®
The LAP-BAND® System was approved by the FDA in June 2001 for use in weight reduction for severely obese adults with a Body Mass Index (BMI) of 40 or more, or for adults with a BMI of at least 35 plus at least one severe obesity related health condition, such as Type 2 diabetes, hypertension and asthma.The name "lapband®" originated from the surgical technique used, laparoscopic, and the name of the implanted medical device, gastric band.
The LAP-BAND® System is a silicone ring designed to be placed around the top portion of the patient's stomach, creating a small gastric pouch and stoma. The inner surface of the band is inflated with sterile saline to create the proper stoma diameter and pouch size. By reducing stomach capacity, the lapband® may help achieve long-term weight loss in overweight and severely obese adults by creating an earlier feeling of satiety thus limiting or reducing food consumption. The LAP-BAND® System is adjustable, which means that the inflatable band can be tightened or loosened to help the patient achieve a level of satiety while maintaining a healthy diet.*
HISTORICAL TIMELINE
| 1985 |
Professor Dag Hallberg, in cooperation with a Swedish medical equipment company, developed the first concept for the gastric band. His work was followed by Dr.Lubomir Kuzmak, who pioneered the technology in the United States. |
| 1986 |
June marked the first use of open adjustable silicone gastric banding (ASGB).
|
1990
|
In April, ASGB was used for the first time in Europe. In December, the first FDA approved ASGB clinical trial started in the United States and the first ASGB workshop was held in Europe.
|
1993
|
The first laparoscopic banding procedure was performed. |
| 1994 |
U.S. based medical device company, Inamed Corporation, created the first workshop for the LAP-BAND System in Europe. |
| 1995 |
The FDA approved the Investigational Device Exemption (IDE) for a clinical study of the LAP-BAND System in the United States. |
| 2001 |
The LAP-BAND® System received FDA approval for commercial distribution. |
| 2007 |
To date, the LAP-BAND® System has been implanted in over 300,000 procedures worldwide. |
