Abstract

Objective: Abdominal wall endometriosis (AWE) is a rare form of extragenital endometriosis that usually develops in association with a prior surgical scar. The purpose of the study was to review the clinical characteristics, diagnostic methods, treatment modalities, and outcomes of patients with AWE.

Methods: A descriptive cross-sectional study was performed in a Gynecology Department of a Portuguese tertiary hospital, concerning patients with histologic-proven AWE, between January 2012 and December 2020 (n = 22). Statistical analysis was performed using IBM SPSS Statistics Version 27.00, with a significance level of p < 0.05.

Results: The most common locations of extrapelvic endometrial ectopic implants were cesarean delivery scar (n = 13, 59.1%) and the umbilicus (n = 5, 22.7%). The median (range) age was 36 (30-42) years old, and all patients had a history of previous surgery but one. Nineteen patients had undergone a previous cesarean section, and the mean (range) time from surgery to the onset of symptoms was 100 (32-168) months. All patients were symptomatic and presented with a palpable mass at physical examination. The majority complained of a painful abdominal mass (n = 20, 90.9%) which was associated with cyclic pain in thirteen patients (65%). Ultrasound scan was performed in all patients and the nodules had a median size of 20.5 mm (5-93 mm). One patient received hormonal therapy and surgical resection was performed in the remaining patients. The nodule’s median (range) size was 31 (12-50) mm on gross examination.

Conclusion: AWE should be considered in the presence of a previous pelvic surgery history associated with abdominal scar cyclic pain and swelling. A careful history and clinical examination are essential for diagnosis to avoid unnecessary delay before surgical intervention.

Keywords: Abdominal endometriosis, endometriosis, umbilical endometriosis, scar endometriosis, cesarean section, pelvic surgery.
