Parastomal hernia repair--Bielañski Hospital experience

The most common occurred long-term stoma complication is parastomal hernia (PH). The incidence of this complication reaches 50% and, according to Goligher, the parastomal hernia is an inevitable consequence in a certain percentage of all cases of stoma formation. The factors that may affect the incidence of parastomal hernia include the site of stoma, particularly its position relative to the rectus muscle of abdomen, preoperative mapping out of the stoma site, stoma diameter, intraperitoneal or extraperitoneal bringing out of the intestine and its fixation to fascia, closing of the area around the stoma opening, the mode of operation--planned or emergency, and finally the kind of stoma--ileostomy, colostomy, end stoma and loop stoma. None of these factors, however, has been identified to have the key importance in parastomal hernia formation. It seems that the only factor that significantly increases the incidence of parastomal hernia is the length of post-operative period.
