The role of appendectomy in gynaecologic surgery: a canadian retrospective case series

To review the indications for, and the associated pathology and complications of, appendectomy performed during gynaecologic surgery in a tertiary academic health sciences centre.

We performed a retrospective review of appendectomy cases performed from September 2007 to December 2011 in a tertiary level gynaecologic surgical practice. Cases were reviewed using a standardized intake sheet with surgical reports, history, and pathologic findings.

A total of 71 appendectomies were performed during gynaecologic surgery in the study period. All cases were primary gynaecologic surgical cases; the most common diagnoses were endometriosis, pelvic pain, and pelvic mass. Overall, 42 (59%) of the study cases had abnormal histopathology in the appendix. Of the 44 women with a primary diagnosis of endometriosis, 28 (64%) had positive appendiceal pathology. In women with chronic pelvic pain, three of eight (38%) had pathology within their appendix. Of all appendixes removed that appeared normal on gross inspection, irrespective of diagnosis, 44% had positive pathology.

When a structured approach is taken towards assessment of the appendix during gynaecologic surgical cases, with removal when indicated, a high rate of pathology may be found. In this series, there were no complications directly related to the appendectomy, providing support for the contention that appropriately trained gynaecologists can safely perform appendectomy. The findings in this Canadian series are in keeping with previous reports and support the need for evaluation and removal of the appendix when indicated at the time of gynaecological surgery.
