Daryl Marx, MD, FACS, FASMBS

Dr. Daryl Marx is a general surgeon specializing in general, bariatric, and robotic-assisted surgery using advanced minimally invasive techniques. He is a Diplomate of the American Board of Surgery and Board Certified by the American College of Surgeons. He is also a fellow of the Society of Laparoscopic Surgeons. These organizations represent the level of commitment that Dr. Marx has to his patients in providing excellent care. These accomplishments are based on a surgeon’s education, training, surgical competence, ethical conduct, professional qualifications and rigorous testing. Dr. Marx offers minimally invasive surgery using the state-of-the-art Da Vinci Robotic Surgical System. He is a specially trained surgeon using techniques to perform complicated surgical procedures with a degree of precision, control and dexterity that traditional surgery cannot match. Dr. Marx is the No.1 robotic surgeon in the South based on volume statistics provided from DaVinci surgical statistics. He has performed over 4,000 robotic cases since he started using the system in April 2012. He is a speaker for DaVinci Robotics, giving presentations over a tri-state area. He currently trains and proctors other surgeons in robotics and routinely has other surgeons travel to observe his cases.

Dr. Marx received his doctor of medicine from Louisiana State University School of Medicine in New Orleans, Louisiana. He continued his surgical internship and residency there, graduating in 2003. While at LSU, he excelled and received several awards for demonstrating outstanding academic and leadership ability. The rigorous training, volume of patients, exposure and responsibility to all aspects of general surgery has well equipped him with surgical excellence. Upon completion of his training, Dr. Marx was most interested in something that he believed was the future of surgery – laparoscopic surgery. This method of surgery uses several small incisions to access the affected area and a “telescope” type instrument inserted to allow the surgeon to operate inside the body without opening the skin. This method of surgery offers less pain and a shorter recovery time for the patient. He enrolled and completed a fellowship in advanced laparoscopic surgery at Louisiana State University Medical Center in Shreveport, Louisiana. This was done in conjunction with Willis Knighton Medical Center. This program gave him the ability to offer many laparoscopic techniques from the very beginning of his solo practice. Dr. Marx regularly attends training and education in any new techniques available. Currently, approximately 90% of his practice is laparoscopic surgery, with most of his surgeries being robotic-assisted. In 2010, Dr. Marx was the only one in the area to offer the single-incision or “scarless” gallbladder surgery. In 2012, Dr. Marx was trained by the DaVinci Group to operate using the newest technology available: the DaVinci Robot. He was the first surgeon to offer this to the people of Northeast Louisiana and is thrilled to bring his knowledge to serve the people of Baton Rouge. This is still laparoscopic surgery that utilizes the special skills and benefits that robotic-assisted surgery can provide.
