2.3 Main outcome measures
The primary outcome measures of interest were: (1) Improvement of
symptoms (pain scores and size of the lesions were used to assess this
outcome measure). The VAS was used to assess the severity of AWE
symptoms, and a higher score was indicative of more severe symptoms; (2)
Intraoperative condition (intraoperative blood loss, time of operation
and the incidence of mesh implantation); (3) Recovery (the length of
hospital stay and the postoperative length of hospital stay); (4)
Adverse events (defined as skin burns, intestinal injury, fever,
infection, anaesthesia-related complications, complications of the
urinary system, and complications of the digestive system); (5) Symptom
recurrence; (6) Reintervention rate (requirements for a new therapy
owing to symptomatic recurrence).
