Amazing Advancements—Robotics Expand Patient Care Options

Published on July 02, 2026

Last updated 04:05 PM July 02, 2026

Robotic surgery has transformed how surgeons care for patients with new innovations yet again. At Wellstar, continued investment in advanced technology is helping elevate surgical care across specialties—giving patients the option to have more precise and less invasive procedures that are easier to recover from.

“Technology continues to advance to provide newer and safer alternatives to treat our patients,” said Dr. Aaron Bolduc, a general surgeon at Wellstar MCG Health Medical Center. “As we adopt this new technology, we are able to lead the way in patient care with excellent outcomes.

Wellstar has expanded its robotic surgery program with the addition of the Da Vinci 5 robotic surgical system—also known as the DV5—at most locations, along with new applications for single-port surgery. These innovations build on years of robotic experience while helping clinicians deliver world-class care and train the physicians of the future.

Fast recoveries

The latest technologies continue to redefine what’s possible in surgery, including even shorter hospital stays and faster recovery timelines.

Dr. Jay Singh, Wellstar chief surgical officer and a colon and rectal surgeon, said significantly smaller incisions make a big impact: “That is potentially huge from the standpoint of patient satisfaction, decreased pain, quicker recovery time, a decrease in narcotics used and a quicker return to work.”

The impact is so great that some robotic procedures that previously required a few nights in the hospital are now being done as outpatient procedures, allowing patients to recover in the comfort of their homes.

DV5: A new level of precision

The DV5 represents a significant step forward in robotic surgery—notably for surgeon awareness and control. One of its most notable advancements is force feedback: “The ability to sense hard and soft tissue during robotic surgeries is a game changer,” said Dr. Julie Chang, an obstetrics and gynecology specialist. She was the first surgeon to use the DV5 system at Wellstar Cobb Medical Center.

“Surgeries will be even more precise and efficient with this tool, which will further reduce post-operative pain and make recovery time faster,” said Dr. Chang.

The machine’s sensory feedback means surgeons can apply the exact amount of pressure needed.

“The DV5 allows the surgeon to sense how much push-or-pull force they apply to delicate structures in the body,” said Dr. Fritz Jean-Pierre, a bariatric surgeon at Wellstar Kennestone Regional Medical Center. “Less strain means less trauma and potential injury, leading to faster patient recovery.”

Wellstar’s robotic program is grounded in decades of experience, combined with a commitment to adopt best‑in‑class technology.

“Having performed robotic surgery for well over 20 years, I started with the very first Da Vinci surgical robot,” said Dr. Scott Miller, Wellstar director of robotic surgical services and a urologist at Wellstar North Fulton Medical Center. “I was amazed when that came around, but I never cease to be amazed by every advancement. Now we have introduced the DV5 model to most Wellstar locations with 10,000 times processing power.”

With that comes enhanced visualization, instrument responsiveness and precision across a wide range of procedures.

“The DV5 is ideal for many urologic procedures, such as prostate and kidney removal, bladder surgery and urinary tract reconstruction,” Dr. Miller said. “The improved range-of-motion and visualization features help us protect healthy tissues and nerves.”

Single-port surgery allows even more precision in getting into tight spots. Instead of making four to six separate incisions, we make one. The flexible instruments can all go through one incision side-by-side and extend like little cobra heads to get at those same angles that once required separate incisions.

One port: Many possibilities

Wellstar has also expanded its use of single-port robotic surgery and brought this technology to more locations, with surgeons at Wellstar North Fulton Medical Center having performed the first single-port gallbladder surgery in the Southeast.

“Single-port surgery allows even more precision in getting into tight spots,” Dr. Miller said. “Instead of making four to six separate incisions, we make one. The flexible instruments can all go through one incision side-by-side and extend like little cobra heads to get at those same angles that once required separate incisions.”

Originally created for urological procedures, single-port technology is now approved by the FDA for a range of surgical approaches.

“The real benefit of single port surgery is since it’s one incision, there is less pain,” said Dr. Gregory Coffman, a general surgeon at Wellstar. “Because of that, recovery is faster and the appearance is also better. A patient’s time to get back to work or their lifestyle is dramatically reduced.”

 

Collaboration & training

Wellstar’s robotic surgery program is also shaping how future surgeons will care for patients across Georgia. At Wellstar MCG Health, robotic platforms are instrumental in surgical education.

“We’re teaching young surgeons how to adopt new technology safely,” Dr. Bolduc said. “This isn’t about one specific robot. We’re teaching them how to safely evaluate and adopt new technology to provide the most benefit to patients.”

Dr. Singh added that these advancements are only possible through strong collaboration: “I'm really proud of the surgeons and our administrative team members—growth of medicine and technology have to work hand-in-hand to provide a higher level of care.”

Together, Wellstar’s investment in medical robotics and surgical expertise continues to expand what’s possible for patients.

How Bariatric Surgery Can Improve Type 2 Diabetes—Even Before Significant Weight Loss

The Weekly Check-up Atlanta


People who seek medical help for weight management are used to hearing that results take time. Imagine the surprise of some patients with type 2 diabetes when their blood sugar improves meaningfully within days or weeks of bariatric surgery.

It happens—and it’s a dramatic sign of the benefits bariatric surgery holds for many patients, said Dr. Fritz Jean-Pierre, a board-certified bariatric surgeon and national leader in minimally invasive and robotic techniques for the treatment of obesity and metabolic disorders.

When changes in blood sugar following bariatric and metabolic surgery were first observed in the 1990s, the reason was a mystery. But today, medical experts know more about the hormones that regulate hunger and insulin production. They also know more about how bariatric surgery affects the same hormones.

Understanding type 2 diabetes: It starts with insulin resistance

Insulin is a hormone that regulates blood sugar. Insulin resistance happens when muscle, fat and liver cells fail to respond to insulin, causing the pancreas to overproduce the hormone. Eventually, blood sugar rises. Patients may develop prediabetes or type 2 diabetes.

Another hormone that affects weight is GLP-1. It’s naturally produced in the gut after eating. GLP-1 helps regulate blood sugar by:

  • Stimulating insulin
  • Suppressing glucagon, a hormone the pancreas produces that raises blood glucose levels
  • Slowing digestion

Many recognize GLP-1 today because of the class of weight-management drugs such as Ozempic, Zepbound and Wegovy. These medications mimic and amplify the effects of the GLP-1 hormone.

How bariatric surgery affects hunger hormones and improves health

Several types of bariatric surgery are performed at Wellstar. While each procedure alters the digestive system differently, all appear to influence the hormones that regulate hunger and blood sugar.

Hormones, such as GLP-1, that promote fullness and insulin sensitivity increase after surgery. The liver produces less excess glucose, and the body becomes more sensitive to insulin. Other hormones—like ghrelin, which signals the brain that the stomach is empty—decrease after surgery.

“We've known since the early 2000s that after bariatric surgery, you have a boost in GLP-1 hormone production,” said Dr. Jean-Pierre. “Patients notice improvements in their blood sugars and that feeling of fullness.”

As a result of hormonal changes triggered by surgery, patients who are not yet on insulin replacement therapy may enter diabetes remission relatively soon, according to Dr. Jean-Pierre.

“The patient may have lost only 5 or 10 pounds yet their blood sugars have become normalized,” he said. “Their diabetes is completely controlled without medication after surgery. That’s the best-case scenario.”

For other patients, improved blood sugar may take longer. Still, clinical trials show that bariatric surgery leads to diabetes remission in 33% to 90% of individuals at one year after bariatric and metabolic surgery.1

“These surgeries are not just changing or shrinking the patient’s stomach,” Dr. Jean-Pierre said. “We're changing their metabolisms in a way that will help improve a lot of related health conditions like high blood pressure, abnormal cholesterol and fatty liver disease.”

Long-term health benefits of bariatric surgery

There are many health risks of type 2 diabetes and obesity. Those include high blood pressure, high cholesterol, sleep apnea and joint pain. Unmanaged diabetes can lead to damage to nerves, kidneys, eyes and heart. Stroke risk is also higher in people with diabetes.

Physicians have more treatment options for obesity than ever, including surgery, medications and lifestyle changes. Wellstar Center of Best Health is a comprehensive weight management clinic with clinicians, dietitians, psychologists and exercise physiologists who work collaboratively with surgeons.

Together, they learn about each patient’s situation and develop a personalized treatment plan with the best chance of success. Some patients may benefit from both surgery and medication.

“Obesity is a chronic, relapsing, multi-variable disease process that we have to approach from different angles in order to best treat it,” said Dr. Jean-Pierre. “You must approach it comprehensively, including nutrition and exercise. Medication itself is not a magic bullet. Surgery is not a magic bullet.”

Wellstar’s weight loss teams support patients throughout their healthcare journey. The goal is to see patients reach their goals and return for follow-up care in even better health.

“It’s amazing when all of these treatment options fire in the right direction and we see the health improvements that come along with surgery,” such as:

  • Better diabetes control
  • Lower blood pressure
  • Less joint inflammation and pain
  • End of the need to use a CPAP for sleep apnea

“Most surgeons fix something, then you don't see your patient again. With bariatric surgery, it's a very different relationship,” Dr. Jean-Pierre said. “We see our patients for a long period of time afterward. We get to share in their successes and see their accomplishments as they lose that weight.”

The Robotic Alliance: Three Specialists, One Purpose

At Wellstar North Fulton Medical Center, something unique is happening in the world of minimally invasive surgery. Nestled right here in Roswell, a multidisciplinary team of robotic surgeons has quietly become one of the most experienced collaborative groups in Metro Atlanta—and across the state of Georgia.

The three surgeons—Dr. Scott Miller (robotic urologic surgery), Dr. Nathan Mordel (robotic gynecologic surgery) and Dr. Jay Singh (robotic colorectal surgery)—have collectively performed close to 9,000 robotic procedures over their careers. While that number is impressive, what it represents matters even more: thousands of patients who have benefited from smaller incisions, faster recoveries and precision that simply wasn’t possible a generation ago.

Although each of the specialties typically addresses distinct conditions, the team often cares for patients whose needs overlap two or even all three areas. These are the moments when a truly coordinated approach matters most. Rather than sending patients to multiple locations or staging separate procedures, the surgeons’ combined expertise allows them to tackle complex, concurrent issues together—efficiently, safely and in one place.

Severe (frozen pelvis) endometriosis is a perfect example of the need for a cooperative surgical approach. This condition affects millions of reproductive age women, invading the genital organs, as well as bladder, ureters, colon and rectum, thus deteriorating their quality of life. Concurrent robotic intervention by urological, colorectal and gynecological surgeons simultaneously treats all three organ systems—and on a mostly outpatient basis.

This collaborative model has become a defining strength of robotic surgery at Wellstar North Fulton. When specialists operate side-by-side, the conversation doesn’t just happen in the clinic—it continues in the operating room, where careful planning and shared experience translate into smoother procedures and better outcomes. Patients may not witness the teamwork directly, but they absolutely feel its benefits during their recovery.

Equally important, Wellstar has invested years in refining our techniques with next-generation robotic systems, which offer enhanced visualization, improved dexterity and precise tissue handling. Whether treating prostate conditions, complex colorectal disease or gynecologic disorders, robotics allows us to deliver the best aspects of minimally invasive surgery while maintaininga high level of surgical control.

Roswell may not be the first place people imagine when they think of cutting-edge surgical innovation, but the reality is that our community has become a hub for it. With a concentrated depth of experience rarely found in a single hospital, Wellstar North Fulton is leading the way in advanced robotic procedures across Georgia.

For us, the mission is simple: three specialties, one purpose—to give every patient access to the highest level of surgical care, in their neighborhood.

Out of Sight, Still a Threat

Five years ago, you probably had hand sanitizer in your car, a thermometer in your bag and a mental checklist for every sniffle. That was life during COVID. But these days? It’s easy to forget what once felt urgent.

The same thing happens with men’s health—especially prostate cancer. For a brief moment, maybe after a friend was diagnosed or during a Movember campaign, it’s top-of-mind. But if nothing seems wrong, it quickly slips to the back burner.

That’s a problem—because prostate cancer doesn’t wait until you’re ready.

At Wellstar, we see too many men surprised by late diagnoses. Why? Because they felt fine. Because they had no symptoms. Because they believed some version of the same three myths:

“Prostate cancer doesn’t kill men.”

Actually, it’s the second leading cause of cancer death in men. When caught early, it’s highly treatable. But when ignored, it’s dangerous.

“I don’t have symptoms, so I’m good.”

Most early-stage prostate cancers are completely silent. No pain, no urinary issues, no warning. That’s why screening matters.

“Testing leads to side effects.”

Screening doesn’t mean treatment. A prostate-specific antigen (PSA) blood test is a simple tool that helps guide the next steps. Many men with slow-growing cancers don’t need surgery—just monitoring. For those who do need treatment, options are far more precise and less invasive than they used to be.

Still, fear or discomfort around the prostate keeps many men from checking in until it’s too late. We get it. It’s not the most glamorous part of the body—but it’s vital.

Think of it this way: you’d never ignore a lump on your neck or blood in your stool. Why ignore the most common cancer in men (besides skin cancer) just because it’s not visible?

Our team at Wellstar makes prostate cancer screening simple, discreet and personalized. We’re here to talk through your family history, explain your risks and offer guidance without pressure. Whether it’s time for a PSA test, a digital exam or just a conversation, we meet you where you are.

Remember: ignoring prostate cancer doesn’t make it go away. It just makes it harder to treat. Learn more about prostate cancer care at Wellstar.
