Prophylactic Mesh Placement During Formation of an End-colostomy: Long-term Randomized Controlled Trial on Effectiveness and Safety.

Objective: The aim of this study was to determine if prophylactic mesh placement is an effective, safe, and cost-effective procedure to prevent parastomal hernia (PSH) formation in the long term.

Background: A PSH is the most frequent complication after stoma formation. Prophylactic placement of a mesh has been suggested to prevent PSH, but long-term evidence to support this approach is scarce.
