ABSTRACT Purpose：A retrospective study was conducted among patients with incisional hernia in our hospital to analyse the factors associated with postoperative recurrence of abdominal wall incisional hernia.

Methods：Patients with a diagnosis of incisional hernia obtained from our hospital's electronic medical record system were divided into primary incisional hernia group and recurrent incisional hernia group according to whether or not they had a recurrence after surgery. Baseline information on these patients was recorded and statistically analysed after our review.
