 For the last decade,
laparoscopic procedures have been used in a variety of general surgeries. Many
people mistakenly believe that these techniques are still "experimental." In
fact, laparoscopy has become the predominant technique in some areas of surgery
and has been used for weight loss surgery for several years. Although few
bariatric surgeons perform laparoscopic weight loss surgeries, more are offering
patients this less invasive surgical option whenever possible.
When a laparoscopic operation is performed, a small video camera is inserted
into the abdomen. The surgeon views the procedure on a separate video monitor.
Most laparoscopic surgeons believe this gives them better visualization and
access to key anatomical structures.
 The camera and surgical
instruments are inserted through small incisions made in the abdominal wall.
This approach is considered less invasive because it replaces the need
for one long incision to open the abdomen. A recent study shows that patients
having had laparoscopic weight loss surgery experience less pain after surgery
resulting in easier breathing and lung function and higher overall oxygen
levels. Other realized benefits with laparoscopy have been fewer wound
complications such as infection or hernia, and patients returning more quickly
to pre-surgical levels of activity.
Laparoscopic procedures for weight loss surgery employ the same principles as
their "open" counterparts and produce similar excess weight loss. Not all
patients are candidates for this approach, just as all bariatric surgeons are
not trained in the advanced techniques required to perform this less invasive
method. The American Society for Bariatric Surgery recommends that laparoscopic
weight loss surgery should only be performed by surgeons who are experienced in
both laparoscopic and open bariatric procedures.
In summary the benefits of laparoscopic gastric bypass include:
- Shorter hospital stay
- Earlier return to work
- Less post-operative pain
- Decreased incidence of incisional hernia, wound infection, and wound
complications
- Cosmetically more appealing
