Dr. diZerega continues to perform research in the area of etiology of pelvic adhesions and prevention of pelvic adhesions following surgical procedures in the female pelvis. In 2000-2001 Dr. diZerega performed research to determine the efficacy of a new agent to prevent adhesions after surgical procedures in the female pelvis. Efficacy and safety of 4% 120 dextran solution was studies in 20 subjects.
