  • Title: Incidental appendectomy during nephrectomy for Wilms' tumor.

    Abstract:
    Incidental appendectomy is frequently performed during nephrectomy for Wilms' tumor. The rationale for this approach is that the onset of appendicitis during a period of neutropenia after chemotherapy may cause increased morbidity. Additionally, children receiving chemotherapy or radiation therapy, or both, may experience abdominal pain, producing a diagnostic dilemma if the appendix is still present. We reviewed the charts of 1,910 children enrolled in the Third National Wilms' Tumor Study who underwent primary nephrectomy. Four hundred and fifty-five patients (23.8 percent) had appendectomy at the time of nephrectomy. An inversion appendectomy was performed upon 188 patients, and the appendix was excised in 267. Infectious complications and postoperative intestinal obstructions occurred with equal frequency in children who did or did not undergo appendectomy. The median follow-up period for the entire group of patients was 5.1 years. Only three of the 1,455 children (0.2 percent) who did not have an incidental appendectomy had appendicitis at two, seven and ten months after nephrectomy. None of the three children experienced any perioperative morbidity after appendectomy. These data suggest that incidental removal of the appendix is not essential for children undergoing removal of a Wilms' tumor.
