Background: Laparoscopy in severely obese patients is a surgical challenge
due to the deep operative field, massive visceral fat, hypertrophic and ste
atotic liver and inadequate instrumentation. However, performing bariatric
surgery by laparoscopy permits a minimally invasive procedure in patients w
ho are usually considered high risk because of their morbid obesity, The ch
allenge was to overcome technical difficulties of laparoscopy in the morbid
ly obese.
Method: We needed to develop a new surgical protocol for the gastric approa
ch in severely obese patients. The existing silicone band could not be used
for laparoscopy, and a new prototype of the silicone band for laparoscopic
use was designed. Because of ethical reasons, we began this work on the an
imal model. In an animal lab program using pigs, we refined the surgical te
chnique of the laparoscopic approach. A new design of the adjustable silico
ne band for laparoscopic use was developed.
Results: After a I-year animal lab program and approval by the ethics commi
ttee, we performed our first human laparoscopic adjustable gastric banding
on September ist, 1993.
Conclusion: The development of the Lap-Band(R) from concept to animal lab,
ending in clinical application, has been an advance in bariatric surgery.
