Abstract

This study aimed to evaluate the cumulative recurrence rate and risk factors for recurrent abdominal wall endometriosis (AWE) after surgical treatment.A retrospective cohort study was conducted at a single gynecological surgery center between January 2004 and December 2020. Patients who were surgically treated and followed up for at least 6 months after surgery were selected.Eighteen patients with pathologically diagnosed AWE were included in this study. The median follow-up duration was 22.5 months (range, 6-106). The median age was 37 years (range, 22-48), and 33.3% of the patients were nulliparous. Among the patients included in our study, 55.6% complained of a mass with cyclic pain, and 27.8% had a palpable mass. In addition, 22.2% of patients experienced recurrence with 17.5±9.7 months of mean time to recurrence. The cumulative recurrence rates at 24 and 60 months after surgical treatment of AWE were 23.8% and 39.1%, respectively. There were no statistically significant risk factors for the recurrence of AWE, including postoperative medical treatment.The recurrence rate of AWE appears to be correlated with the follow-up duration. There was no statistically significant risk factor for the recurrence of AWE. Unlike ovarian endometriosis, postoperative hormonal treatment does not seem to lower the recurrence of AWE. The findings of the current study may help healthcare providers in counselling and managing patients with AWE.

TL;DR

In a single-institution retrospective cohort of 18 patients with surgically treated abdominal wall endometriosis (AWE), recurrence occurred in 22.2% at a mean of 17.5±9.7 months, with cumulative recurrence rates of 23.8% at 24 months and 39.1% at 60 months. No statistically significant risk factors for recurrence were identified, including postoperative medical treatment.

Key findings

  • Among 18 pathologically diagnosed AWE patients, 22.2% experienced recurrence; mean time to recurrence was 17.5±9.7 months.
  • Kaplan-Meier cumulative recurrence rates were 23.8% at 24 months and 39.1% at 60 months after surgical treatment.
  • No statistically significant risk factors for recurrent AWE were found, including mass size, cyclic symptoms, previous operation type, interval between recent surgery and AWE surgery, pre- or postoperative medical treatment, and association with ovarian endometrioma.
  • One patient was diagnosed with clear cell carcinoma arising from AWE, with subsequent inguinal lymph node metastasis and recurrent disease despite surgery and adjuvant paclitaxel-carboplatin chemotherapy.

Methods

  • Retrospective cohort study at a single gynecological surgery center between January 2004 and December 2020; patients surgically treated for AWE and followed for at least 6 months were included.
  • Of 56 clinically diagnosed AWE patients, 34 underwent surgical treatment, and 18 were followed for at least 6 months and included in the analysis.
  • Data were collected by medical chart review; categorical variables used chi-square and Fisher’s exact tests, quantitative variables used Mann-Whitney U test after Shapiro-Wilk normality testing, cumulative recurrence was assessed by Kaplan-Meier method, and Cox proportional hazards models were used for risk-factor analysis with p<0.2 for univariate entry and p<0.05 for significance.

Limitations

  • Stated: the study was retrospective; the number of surgically treated patients followed for at least 6 months was too small to generalize the results.
  • Stated: the tissue involved in AWE was not evaluated, which could be a possible risk factor for recurrence; many patients were lost to follow-up after surgical treatment, and postoperative medical treatment duration was often relatively short.
  • Evident from the text: findings come from a single institution and a rare disease cohort, and one patient with clear cell carcinoma arising from AWE was included, which may limit applicability to typical AWE populations.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
