Pelvic exenteration: a morbidity and mortality analysis of a seven-year experience

Twenty patients have undergone pelvic exenteration at the University Hospital of the Pennsylvania State University from 1979 to 1985. The majority of operations were performed for cancers of the cervix or vagina that recurred following radiotherapy. Operative mortality was 5.0%. Of those surviving the procedure, 16 patients (84%) were rehospitalized for complications that occurred more than 30 days after exenteration. The majority of these involved the gastrointestinal or urinary tracts. Fifty-eight percent of the complications requiring surgical intervention occurred more than 1 year after surgery while 74% of the complications managed conservatively occurred within 1 year of surgery. The 2-year survival for all patients was 70%; survival decreased to 58% at 5 years. The most important risk factor for reduced survival was the extension of tumor laterally into the surgical margins.
