Prophylactic retromuscular mesh placement for parastomal hernia prevention: a retrospective cohort study of permanent colostomies and ileostomies

Incidence and risk factors for parastomal hernia with a permanent colostomy

“…Because of the fear of stoma necrosis or stenosis, most doctors have made the stoma diameter very large in clinical practice, and more and more studies have shown that the stoma diameter is too large is the risk factor of inducing parastomal hernia. 2 The research of de Ruiter et al used the principles of physics to incisively explain the mechanical relationship between the size of stoma diameter and the formation of parastomal hernia. 3 They believe that the abdominal stoma is affected by two forces, the tangential force parallel to the stoma (Ftang) and the radial force perpendicular to the stoma (Frad), in which Ftang is the main force causing parastomal hernia.…”
