| Objective To analyze the clinical characteristics of patients with abdominal wall endometriosis (AWE) after pelvic surgery.Methods The clinical data of 93 patients with AWE after pelvic surgery were collected from January 2011 to December 2017 in the First Affiliated Hospital of Anhui Medical University, and these data were retrospectively analyzed, including the clinical signs, image features, surgical treatment and efficacy.Results Among 93 patients, 58.1% of them had a mass beside the abdominal wall incision as the first symptom, and 41.9% of them had a pain in the abdominal wall incision during menstruation as the first symptom.In addition, 88.2% of the patients had a single mass and 11.8% had multiple masses; 64.44% of the masses were located on both sides of the transverse incision and 35.48% were located on the upper and lower ends of the longitudinal incision. Among the 70 patients who underwent ultrasonic examination, 50.53% of the masses were oval or round with hypoechoic image andnocapsule; 24.73% of the masses were hyperechoic areas with unclear boundaries and small anechoic areas. Among the 23 patients who underwent MRI examination, 19.35% of the lesions had blurred boundary; 13.98% showed solid mass with high signal intensity on T1WI and mixed signal intensity on T2WI; 10.75% of the lesions showed cystic and solid masses, mainly isohypointensity on T1WI, and mixed hypointensity on T2WI.The lesions were significantly enhanced after enhanced scanning. All patients were treated by abdominal surgery and the incisions were healed by first intention. All patients were followed up for 6~85 months and 5 cases recurred.Conclusions The primary symptom of AWE patients after pelvic surgery is abdominal incision mass, and some of them are accompanied with menstrual pain.Ultrasonography shows abnormal echo mass without capsule and unclear boundary. On MRI, the lesions show mixed signal intensity and are significantly enhanced after contrast enhancement.The therapeutic effect of transabdominal resection is good. |
