Advantages, complications and contraindications of 1–4double-barrel wet colostomy

Modified double-barrel wet colostomy
Advantages versus classical double diversion Main complications Contraindications
General urinary complications
(range %)
Specific urinary complications
(range %)
Single stomaPyelonephritis
(0–13.4)
Anastomotic stenosis
(0–11.1)
Insufficient colon length
Shorter operating time and length of stayElectrolyte abnormalities
(0–33.3)
Anastomotic leak
(0–18.6)
Insufficient ureteral length
Formation of a separate urinary diversion in the small bowel (frequently irradiated) is avoidedUrinary fistula
(0–14)
Similar perioperative complication rates (mortality <30 days, postoperative complications, re-operations)Risk of intestinal carcinoma origin at the uretero-intestinal anastomotic site
Similar long-term complication rates (pyelonephritis, electrolyte disturbances, urinary anastomotic problems)
Improved quality of life
