[Treatment of parastomal colostomy hernia]

Parastomal hernias are the most common cause of in patients surgically with stomy reoperation treated.

Treatment of parastomal hernias has been faced through two kind of technics: the first one consisted in the translocation of colostomy, the second one was placing around the colostomic hole a marlex mesh which was inserted at muscular structure level. From January 1993 to May 1997 we treated 8 patients affected by paracolostomic hernia associated to laparocele. The laparocele was treated according Rives' technique with the prosthesis positioned in the properitoneal site. The parastomal hernia was treated with translocation of the colostomy in 3 cases; in the other patients a plastic surgery of the colostomic orifice was made using polypropylene little bandages in properitoneal site.

In the postoperative period the complications concerned a single case of skin parcellar necrosis, that healed spontaneously with medications and a case of prolonged serous secretion the mean follow-up was 2 years from the wound.

In our experience the use of marlex mesh may be effective in treatment of parastomal hernia only a patient treated with translocation of the stoma showed a recurrence of parastomal hernia. The positioning of the prosthesis at properitoneal level is subject to a lower incidence of recurrent parastomal hernia.
