MUSC Digestive Health brings together gastroenterologists, surgeons, and radiologists who have special interests in dealing with various digestive problems. It is our goal to provide comprehensive clinical services for patients with known or suspected digestive issues, incorporating the disciplines of gastroenterology, hepatology, nutrition, pediatric services ... plus many others.
The management of digestive diseases, which has improved enormously over the last two to three decades, has also become more complex as the number of treatments has rapidly grown. The challenge is to combine the proper care using the most effective treatments in combination with competent and caring medical advice.
The majority of patients are managed with medical, endoscopic, and non-operative therapies; but, when these treatments are ineffective, patients are referred for surgical management. This has made it essential for specialists of different expertise to work together to provide the most effective and efficient treatment for their patients.
