Background:
Minimally invasive intestinal stoma formation using a laparoscopic approach or through a trephine, is widely described in published literature. The incidence of parastomal hernia (PH) following a stoma formed without formal laparotomy is not well reported. The present review aims to assess the current data available on minimally invasive stoma formation, with particular reference to the incidence of PH.
Methods:
A literature search using the Pubmed Medline database was performed, locating English language articles on minimally invasive stoma formation from 1970 to 2002. The manuscripts were searched manually for further references.
Results:
The number of published studies describing laparoscopic stoma formation is small (263 stomas) and the follow-up studied were short (none longer than 1 year). The incidence of PH was 0-6.7%. The incidence following a trephine stoma was 6.7-12%, and the number of patients was small (118) and the follow up short (up to 12 months).
Conclusions:
The incidence of PH following minimally invasive stoma formation using a trephine or a laparoscopic technique remains unclear. Studies published to date are generally small and the follow up is short. A prospective randomized trial comparing minimally invasive stoma formation with stoma formation with laparotomy, is required.
