PINEHURST, N.C. -- Advancements in bariatric surgery are transforming how patients experience weight loss procedures, from faster recovery times to safer, more effective outcomes.
In a recent episode of the FirstHealth and Wellness Podcast, Dr. David Grantham and Dr. Raymond Washington, surgeons at the Metabolic and Weight Management Center, sat down to discuss what’s new in bariatric surgery, including robotic-assisted procedures and bariatric revision surgery.
Below, we break down the conversation into key questions and answers.
What’s new in bariatric surgery today?
Dr. Grantham: One of the biggest advancements is robotic-assisted bariatric surgery. Over the last few years, our program has adopted robotic technology, and the benefits for patients have been significant. Patients are recovering faster, experiencing fewer complications, and often going home sooner than with traditional approaches. Outcomes have been excellent, and patient satisfaction is noticeably higher.
How has robotic surgery changed the patient experience?
Dr. Washington: Compared to 20 years ago, bariatric surgery today is a completely different experience. Procedures are done through smaller incisions, which lowers the risk of infection and hernias. Most patients stay in the hospital just overnight and return to work in about 2 weeks. Complication rates are much lower, and in fact, bariatric surgery is now considered safer than some routine procedures.
What advantages does robotic-assisted surgery offer?
Dr. Grantham: Robotics gives surgeons a three-dimensional, magnified view and wristed instruments that allow for more precise, natural movements. This is especially helpful when suturing or working in tight spaces during procedures like gastric bypass. Despite the name, the surgeon is always in control. The robot is simply an advanced tool that enhances precision and visibility.
What bariatric procedures are offered at the Metabolic and Weight Management Center?
Dr. Washington: We primarily offer two procedures:
- Sleeve Gastrectomy: About 80% of the stomach is removed, helping patients lose 50 to 70% of their excess body weight within 9 to 18 months.
- Gastric Bypass: Considered the gold standard, this procedure is both restrictive and malabsorptive, leading to 60 to 80% excess weight loss.
Both procedures are performed robotically, typically require just an overnight hospital stay and allow patients to return to work in about two weeks.
What is bariatric revision surgery?
Dr. Grantham: Bariatric revision surgery is for patients who have already had a weight loss procedure but need a change due to symptoms or insufficient results. Common revisions include removing outdated gastric bands and converting them to a sleeve gastrectomy or gastric bypass. Another frequent reason for revision is severe acid reflux after a sleeve procedure, which can often be resolved by converting to a gastric bypass.
Why might someone need a revision surgery?
Dr. Washington: The most common reasons are persistent reflux, inadequate weight loss or complications from older procedures. Gastric bypass is especially effective in resolving heartburn and controlling reflux, while also providing strong, long-term weight loss outcomes.
What does the future of bariatric surgery look like?
Dr. Grantham: The future is exciting and multifaceted. Surgery will continue to evolve alongside endoscopic treatments and weight-loss medications like GLP-1 therapies. Our goal is to provide the right combination of treatments for each patient while keeping safety at the forefront.
Dr. Washington: Long-term success is about more than surgery. Our multidisciplinary approach includes nutrition, behavioral support, and lifelong follow-up to help patients maintain weight loss and improve overall health.
