Laparoscopy in the prevention of unnecessary appendicectomies: a prospective study.

More than one-third of all appendicectomies are unnecessary. A study was directed towards reducing the misdiagnosis of appendicitis, thus preventing needless operations. Thirty-six women in the fertile age group and with a diagnosis of appendicitis were subjected to laparoscopy before surgery. All women had undergone a gynaecological examination to rule out disease of the female genitalia. As a result of the laparoscopy, surgery was cancelled in one-third of the cases, which were found to have acute gynaecological disease not requiring surgery.
