Beyond the scar: a retrospective analysis of a rare subtype of abdominal wall endometriosis with muscle fascia invasion and its surgical implications
摘要
Abdominal wall endometriosis (AWE) is a rare form of extrapelvic endometriosis, often developing after cesarean section. While typically presenting as a painful mass near surgical scars, its diagnosis is frequently delayed. This study investigates the clinical features, muscle fascia involvement, and surgical outcomes in patients with AWE.
MethodsA retrospective review was performed on 21 patients with histologically confirmed AWE treated surgically at a tertiary care center between January 2016 and December 2020. Patient demographics, clinical presentation, lesion characteristics, fascia involvement, surgical techniques, and recurrence rates were analyzed.
ResultsAll patients had a prior cesarean section. The most common symptom was a cyclic painful mass (76.2%). Muscle fascia invasion was detected in 42.9% of cases. Polypropylene mesh repair was used in defects ≥ 3 cm. Only one recurrence (4.8%) was observed during a mean follow-up of 22 months. A strong correlation existed between physical and radiologic lesion size (r = 0.923), and between symptom duration and time since cesarean (r = 0.579).
ConclusionAWE should be considered in women with abdominal wall masses and cesarean history. Wide excision is effective, and mesh repair offers reliable outcomes in fascia-invading cases. Early recognition and tailored surgical planning help minimize recurrence.
