Cumulative Recurrence Rate and Risk Factors for Recurrent Abdominal Wall Endometriosis after Surgical Treatment in a Single Institution

다국어 초록 (Multilingual Abstract)

Purpose: This study aimed to evaluate the cumulative recurrence rate and risk factors for recurrent abdominal wall endometriosis(AWE) after surgical treatment.
Materials and Methods: A retrospective cohort study was conducted at a single gynecological surgery center between January2004 and December 2020. Patients who were surgically treated and followed up for at least 6 months after surgery were selected.
Results: Eighteen patients with pathologically diagnosed AWE were included in this study. The median follow-up duration was22.5 months (range, 6–106). The median age was 37 years (range, 22–48), and 33.3% of the patients were nulliparous. Among thepatients included in our study, 55.6% complained of a mass with cyclic pain, and 27.8% had a palpable mass. In addition, 22.2% ofpatients experienced recurrence with 17.5±9.7 months of mean time to recurrence. The cumulative recurrence rates at 24 and 60months after surgical treatment of AWE were 23.8% and 39.1%, respectively. There were no statistically significant risk factors for therecurrence of AWE, including postoperative medical treatment.
Conclusion: The recurrence rate of AWE appears to be correlated with the follow-up duration. There was no statistically significantrisk factor for the recurrence of AWE. Unlike ovarian endometriosis, postoperative hormonal treatment does not seem to lower therecurrence of AWE. The findings of the current study may help healthcare providers in counselling and managing patients with AWE.
