hiatal hernia and GERD.
His training in bariatric surgery techniques was under Dr. Alan Whitgrove
and Dr. Paul O'Brien, two of the most respected leaders in the field of
bariatric surgery worldwide. He was the first surgeon to perform laparoscopic

Peter W. Lundberg, MD
Having completed fellowship in advanced minimally invasive techniques and
bariatric surgery, Dr. Peter Lundberg is one of the most prolific laparoscopic
surgeons in Southern Louisiana. He was the first surgeon at our institution
to utilize robotics in performing sleeve gastrectomy, gastric bypass,
duodenal switch, and several other complex gastrointestinal procedures.
He frequently takes on complex revisional bariatric surgeries, offering
patients renewed chances at weight loss and comfort when their initial
outcomes are not optimal. Dr Lundberg is also among the most experienced
robotic surgeons in the area for hernia surgery and anti-reflux surgery.
“Laparoscopy, in concert with robotics, is the present
and future of surgery. Surgeries are safer, outcomes better, pain less and
cosmetic results superior with the technology at our disposal.”
Dr Lundberg is certified by the American Board of Surgery and has been
extensively published in general and bariatric surgery literature. His
training affords a personalized approach for every patient to ensure a
safe, satisfactory outcome with minimal pain and a rapid recovery.
He also maintains leadership roles in both the state and national chapters
of the American Society for Metabolic and Bariatric Surgery and is a tireless
advocate for educating patients, providers, employers, and legislators
on the benefits of weight loss surgery. His greatest passion, however,
is establishing meaningful relationships with patients - to listen, understand,
and honestly find the best way forward as a team.
