Abdominal wall endometriosis: a surgeon's perspective and review of 445 cases.

BACKGROUND

Abdominal wall endometriosis (AWE) is defined as endometrial tissue superficial to the peritoneum. AWE often is misdiagnosed and referred to surgeons for treatment. We performed a systematic review of published cohorts to quantify demographics, symptoms, and outcomes of patients having AWE.

METHODS

An English language PubMed search from January 1951 to August of 2006 was conducted using several search terms for endometrioma.

CONCLUSIONS

Twenty-nine articles describing 455 patients were identified and met inclusion criteria. The pooled mean age was 31.4 years. Ninety-six percent presented with a mass, 87% presented with pain, and 57% presented with cyclic symptoms. AWE was associated with a caesarian scar or hysterectomy in 57% and 11% of cases, respectively. The interval from index surgery to presentation was 3.6 years. Recurrence after resection was 4.3%. The most common presentation of AWE is the development of a painful mass after uterine surgery. Surgical treatment appears to result in a cure more than 95% of the time.
