“…12 Sporadic cases of appendiceal endometriosis causing an appendicoduodenal fi stula have been documented. 13 Endometriosis of the appendix is reported to be often associated with leiomyoma of the uterus and menstrual abnormalities. 5,6 However, our patient had no history of these abnormalities, and her symptoms did not coincide with her menstruation.…”

Laparoscopic Appendectomy for Appendiceal Endometriosis Presenting as Acute Appendicitis: Report of a Case

et al. 2007

Endometriosis is a relatively common disorder in women of reproductive age; however, appendiceal endometriosis is rare. Thus, a definitive diagnosis is likely to be established only by histology of the appendix. We report a case of endometriosis of the appendix in a 42-year-old woman who presented with symptoms of acute appendicitis. We treated the patient by performing laparoscopic appendectomy, which resulted in a good outcome.

“…Appendiceal fistulae projecting to the small bowel have been found to communicate with the ileum, jejunum, and duodenum . As expected, fistulae between the appendix and the ileum are most common due to their close proximity, with the first case reported by Volz in 1846 .…”

Background The appendix has a unique place in surgical history. Although the first ever appendicectomy involved a fistula to the skin, fistulae involving the appendix remain uncommon and can lead to unique surgical considerations. Methods A systematic review of the literature was performed for case reports of appendiceal fistulae. We excluded cases in which the patient had a history of appendicectomy. Cases were categorized by site and aetiology, with information regarding relative frequency and demographics obtained. Results A total of 301 case reports of fistula involving the appendix were found. The most common sites of these fistulae were to the bladder (148 cases), skin (40 cases), vasculature (19 cases), umbilicus (16 cases) and to the gastrointestinal tract. The most common aetiology in sub‐analysis was appendicitis alone (150 cases), with less common causes including appendiceal adenocarcinoma (32 cases) and congenital abnormalities (18 cases). There were significantly more appendiceal fistulae in males than in females, with a ratio of 1.7:1. In patients with appendiceal adenocarcinoma as a cause for fistula, there were significantly more females than males with a ratio of 2.3:1. Conclusion In conducting a systematic review of case reports of fistulae involving the appendix, we identified 301 unique case reports, with a range of different sites and aetiologies.
