His clinical practice is mainly directed to diagnosis and treatment of colo-rectal-anal diseases, and he has expertise in performing ano-rectal and pelvic floor diagnostics tests (e.g. anorectal manometry and endoanal and transrectal ultrasound) and treatment. He is an active member of the Italian Society of Colorectal Surgery (SICCR) and is the author of several publications in international journals and numerous book chapters. He has also presented his research at national and international scientific conferences. Francesco Litta is an attending physician at the Proctology Unit of the Foundation University Hospital "A. Gemelli", Rome, Italy, directed by Prof. Carlo Ratto. His clinical practice focuses mainly on the diagnosis and treatment of diseases of the colon and the rectum, and all proctological diseases. He is involved in anorectal physiology testing, with particular interest in the evaluation of benign and malignant disease using anorectal manometry and three-dimensional endoanal ultrasound. . He is active member of the Italian Society of Colorectal Surgery (SICCR). Veronica De Simone works at the Proctology Unit of the Foundation University Hospital "A. Gemelli", Rome, Italy, directed by Prof. Carlo Ratto. Her clinical practice focuses on the diagnosis and treatment of benign and malignant colorectal and anal diseases. She has developed a particular expertise in the diagnosis and management of anal and perianal HPV-related disease, performing anal cancer screening and second level diagnostic tests (high resolution anoscopy) in high risk populations (HIV+, transplant recipients, inflammatory bowel diseases). She is active member of the Italian Society of Colorectal Surgery (SICCR) and of the International Anal Neoplasia Society (IANS). Paola Campenni is a surgeon of the Proctology Unit of the Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome.
