Dr. Chiaretti acquired deep theoretical knowledge about Physiology and Intestinal Pathophysiology. He studied in depth the intestinal immune system in critical patients, neoplastic patients, and inflammatory bowel diseases. As long as inflammatory intestinal diseases are concerned, he gave his important contribution to clinical and pathophysiological factors at the base of the surgical strategy to adopt, the factors that can influence the improvement of the immune response, and his contribution in the search and application of the most effective parameters to examine the evolution of the disease and reduce the risks of complications. He dealt much with the Clinical Nutrition of the neoplastic patient, and the building of an appropriate care protocol with Postoperative Early Enteral Nutrition in the critical patient.
