Recover Faster With Advanced Colorectal Surgery

Feel comfortable, confident and supported at every step of your digestive health journey. Whether you’re facing anorectal concerns, colorectal cancer, anal dysplasia or inflammatory bowel disease, you can trust you’re in expert hands. We take the time to understand your symptoms and walk you through your treatment options.

With six board-certified, fellowship-trained surgeons, we’re the largest colorectal surgery group in the area — giving you faster access to advanced, specialized care when you need it most. Our team performs minimally invasive surgeries with robotic-assisted technology to treat complex colorectal conditions, allowing you to get back to the life you love faster with less pain, a shorter hospital stay and quicker recovery time.

Heal Faster With Robotic-Assisted Surgery

We understand that surgery is a big decision. At AdventHealth, you can rest easy knowing we’re dedicated to safer, smarter surgeries that help you heal faster. That’s why we often perform minimally invasive surgeries using robotic technology.

Robotic-assisted surgery helps our surgeons perform complicated and delicate procedures with more precision, control and flexibility than traditional surgical techniques allow. More importantly, these procedures have meaningful benefits for you, including:

  • Faster return to everyday routines
  • Fewer complications
  • Less blood loss and fewer transfusions
  • Less scarring
  • Lowered risk of infection
  • Shorter hospital stays

If surgery is your best next step, our board-certified surgeons will create a personalized treatment plan for you, which may include a robotic-assisted procedure. At every step of your treatment, our experts will work together with you to meet your needs and recovery goals successfully.
