Respected Colorectal Surgeon Joins Southside Hospital

BAY SHORE, NY… David E. Rivadeneira, MD, MBA, FACS, FASCRS has joined Southside Hospital as full time faculty. In addition, he was named Vice Chair of Surgical Strategic Initiatives for the North Shore-LIJ Health System’s Eastern/Suffolk Region.

An accomplished colorectal surgeon who is board-certified in both general surgery and colon and rectal surgery, Dr. Rivadeneira’s main focus is on minimally invasive, complex colorectal procedures. He is one of the few surgeons in the Northeastern United States who performs single incision laparoscopic surgery (SILS) and robotic colorectal procedures using the DaVinci Surgical System. SILS is a minimally invasive surgical procedure in which the surgeon operates almost exclusively through a single entry point, most commonly the patient’s navel. Unlike traditional, multi-incision laparoscopic surgery, SILS leaves only a single small scar.
“I don’t think you have to sacrifice quality or that individualized care in a community hospital setting for state-of-the-art surgical technology,” said Dr. Rivadeneira.  “At Southside Hospital, patients receive the best of both.”

Dr. Rivadeneria just got voted a top doctor by Castle Connolly  in the field of colon & rectal surgery.
"The addition of a top-flight surgeon such as Dr. Rivadeneira, is a great step forward for Southside Hospital, and is the result of our focus on providing the most advanced care across a range of programs" said Donna Moravick, the hospital’s executive director.  "This respected surgeon brings a wealth of knowledge and expertise to our hospital and to the region, where patients requiring the most advanced colorectal interventions often had to travel some distance to attain them.  Now, they can have these procedures right in our community, with their families and their own doctors nearby."
A graduate of Howard University College of Medicine in Washington, DC, with honors, Dr. Rivadeneira completed his surgical training at Memorial Sloan-Kettering Cancer Center and New York Presbyterian Hospital, Cornell Medical Center, where he served as Chief Resident. He completed a National Institutes of Health (NIH) surgical oncology research fellowship also at Cornell University Medical College, as well as a fellowship in colon and rectal surgery at the Lahey Clinic Medical Center in Burlington, Massachusetts where he received an award for outstanding academic achievement.  For five years, Dr. Rivadeneira was a member of Stony Brook University Medical Center’s full-time faculty where he was an associate professor of surgery.
Internationally recognized as a leader in the field of colorectal surgery, Dr. Rivadeneira is a coeditor of “Minimally Invasive Approaches to Colon and Rectal Disease: Techniques and Best Practices,” a textbook for surgeons and medical students throughout the country. Dr. Rivadeneira has published his research in numerous professional journals and serves as a reviewer for several, including Diseases of the Colon and Rectum; Gastroenterology and Hepatology; Endoscopic and Laparoscopic Surgery; and World Journal of Surgery. He has also presented his research at professional conferences throughout the United States and abroad. Dr. Rivadeneira is a fellow of the American College of Surgeons, the Society of Surgical Oncology, and the American Society of Colon and Rectal Surgeons.
Dr. Rivadeneira’s colleagues, Drs. Jacob Eisdorfer and Cesar Sanz, have joined Southside Hospital as well to further develop the hospital’s colorectal program.
