Factors affecting hernia recurrence after Strattice mesh repair: A retrospective study

Abstract

Aim The aim of the present study was to explore the factors that affect hernia recurrence after Strattice mesh repair. Patients and Methods The present study is a retrospective study of the medical records of 42 patients who underwent Strattice mesh hernia repair at Ruby Memorial Hospital, West Virginia University. Strattice mesh was employed in a variety of ventral hernia procedures, including primary ventral hernia repair, recurrent ventral incisional hernia repair, component separation (abdominal wall reconstruction), parastomal hernia repair and infected inguinal hernia repair. The main collected variables were body mass index, intraoperative hernia defect size, diabetes, wound events and steroid use. Results For 42 patients, the overall recurrence rate was 21.43 per cent. The mean body mass index (BMI) was 36.4. BMI and sex were significant risk factors for recurrence (P = 0.036, P = 0.002), respectively. The mean defect size was 97 cm2. The hernia defect size was not significantly associated with the hernia recurrence rate (P = 0.166). Of the 10 diabetics, five developed recurrence. However, diabetes was not significantly associated with the hernia recurrence rate (P = 0.726). A total of four patients (9.52 per cent) were using steroids; one developed recurrence, which was not significantly associated with the hernia recurrence rate (P = 0.20). Wound infection also was not significantly associated with recurrence (P = 0.323). Conclusions Only sex and an increase in the BMI were significantly associated with the risk of hernia recurrence. In order to decrease the modifiable risk of hernia recurrence, surgeons should counsel obese patients regarding preoperative weight loss.
