title: Literature Review: Double-Barrelled Wet Colostomy (One Stoma) versus Ileal Conduit with Colostomy (Two Stomas).
abstract: BACKGROUND
  The aim of this literature review was to analyse the advantages and disadvantages of a traditional ileal conduit (IC) with separate colostomy technique compared to the outcomes of a double-barrelled wet colostomy (DBWC) technique. The former technique results in the formation of two stomas, and the latter results in the formation of one stoma.
  
  
  METHODS
  PubMed was searched electronically for articles on DBWC. Fifteen articles were retrieved and of them 13 were included in the literature review (350 patients). Of the articles, 3 directly compared DBWC to IC with colostomy.
  
  
  RESULTS
  Review of 13 DBWC articles demonstrated perioperative mortality ranging between 0 and 11.1% and postoperative complications ranging from 0 to 100%. Three of the studies directly compared DBWC to IC with colostomy; median operating times and length of stay were shorter in DBWC patients (p < 0.001); 30-day morbidity was reported to either be lower in the DBWC group (p < 0.043) or to have no statistically significant difference. Rates of mortality, pyelonephritis, electrolyte disturbances and urinary anastomotic problems did not differ between the 2 groups.
  
  
  CONCLUSIONS
  The DBWC technique inherently has a benefit over the IC with colostomy technique, as it requires only one stoma. This literature review supports the use of the technically less challenging DBWC technique as a viable alternative to the traditional IC with colostomy technique.
