Risk assessment tool for complications after hernia repair which include: grade 2 (history of wound infection, comorbidities); grade 3 (presence of a stoma, violation of the gastrointestinal tract); and grade 4 (presence of mesh infection and septic dehiscence. Of note, no patients with septic dehiscence were enrolled and only patients with actively treated, chronic mesh infections were included per the inclusion/exclusion criteria.
VHWG = Ventral Hernia Working Group classification; PCS = posterior component separation; ACS = anterior component separation; OR = operating room; SD = standard deviation.
