Stoma creation is associated with a low incidence of midline incisional hernia after colorectal surgery: the “fighting over the fascia” theory concerning the incision and stoma hole
Parastomal hernia (PH) develops more frequently than incisional hernia (IH) after colorectal surgery with stoma. This study evaluated our hypothesis that inward traction of the fascia when closing a midline in...
