[Prevention of post appendectomy incision abscess with the use of polyvinilpyrrolidone iodine (prospective study)]

365 appendicectomy cases performed from 1972 to 1976 were studied prospectively. In 135 control cases the wound was not lavaged. In 102 cases the wound was lavaged with normal saline solution. En 108 cases the wound was lavaged with PVP-I. Wound abscess formation rate in the first group was 28.8%, in the second group was 21.35% and in the third group was 18.5%. Patients operated after 1974 and treated with PVP-I showed a 4.2% abscess formation. Morbility and mortality in appendicitis are best reduced if early diagnosis and surgical treatment are backed by a faultless technic.
