Progress of prevention and surgical treatment for parastomal hernia

Prevention and surgical treatment of para stomal hernia remain a major challenge to surgeons. The effects of traditional nonoperative and surgical treatment would likely be few, but the application of surgical technique which places a prophylactic mesh at the primary operation is bringing down the incidence of parastomal hernia in recent years. Due to a high recurrence rate of parastomal hernia after traditional in or ex situ tissues repair，the shortterm outcomes of surgical treatment for parastomal hernia have significantly been improved by using prosthetic mesh, while the longterm outcomes are uncertain and needed for further investigation.
