Michael Patrick Del Rosario, M.D., is a double board-certified and fellowship-trained colorectal surgeon at Southern Ocean Medical Center. A pioneer in his field, he was the first surgeon in the area to perform minimally invasive colon resection and has been continuously serving the South Jersey community since 2003.


Dr. Del Rosario specializes in advanced laparoscopic and robotic surgery, techniques that enhance surgical accuracy while shortening hospital stays and recovery times. He is accredited as a Surgeon of Excellence in Robotic Surgery at Southern Ocean Medical Center by the Surgical Review Corporation.


His practice is dedicated to the comprehensive treatment of both malignant and benign colorectal conditions. This includes colon and rectal cancers, diverticulitis, inflammatory bowel disease (Crohn's and ulcerative colitis), and a full range of anorectal problems such as hemorrhoids, fissures, and complex fistulae.


After earning his medical degree from SUNY Downstate College of Medicine, Dr. Del Rosario completed his General Surgery residency at RWJ Barnabas Medical Center and a specialized fellowship in Colon and Rectal Surgery at the University of Illinois.


Dr. Del Rosario's dedication to the highest standards of cancer care is further demonstrated by his role on the HMH Cancer Committee, which works to maintain the network's accreditation as an American College of Surgeons Surgical Quality Partner. 


He is a strong advocate for patient education and frequently gives free seminars to the public. In his personal time, he enjoys spending time with his children and enjoying the South Jersey shore, where he is an avid SCUBA diver and fisherman.


Frequently Asked Questions (FAQs)


1. What are the benefits of robotic surgery for colon cancer?


Robotic surgery is a form of minimally invasive surgery that allows for enhanced 3D vision and greater precision. For patients, this translates to smaller incisions, less pain, a shorter hospital stay, a faster return to normal activities.


2. When should I get a colonoscopy?


For individuals at average risk, screening colonoscopy is recommended to begin at age 45. It is the most effective tool we have for both preventing colorectal cancer by removing precancerous polyps and detecting cancer at its earliest, most treatable stage.


3. What are common conditions you treat?


I treat a wide range of anorectal issues, including hemorrhoids, anal fissures (small tears), and anal fistulas (abnormal tunnels). While these conditions can be uncomfortable to discuss, they are very common, and there are many highly effective, minimally painful treatments available to provide relief.


4. What is diverticulitis?


Diverticulitis is the inflammation or infection of small pouches that can form in the wall of the colon. While many cases can be treated with medication, recurrent or complicated cases may require surgery.

Philosophy of Care

My philosophy is rooted in patient education and empowerment. I believe that when patients have a clear understanding of their condition and all their treatment options, they are better equipped to make the best decisions for their own health. I take the time to explain complex issues in an accessible way, ensuring we can work together as a team.

By combining this collaborative approach with the latest minimally invasive surgical techniques, my goal is to provide not only the most effective treatment but also a supportive and reassuring experience that restores both health and quality of life.
