Advantages, complications and contraindications of 1–4double-barrel wet colostomy
| Modified double-barrel wet colostomy | |||
| Advantagesversusclassical double diversion | Main complications | Contraindications | |
| General urinary complications (range %) | Specific urinary complications (range %) | ||
| Single stoma | Pyelonephritis (0–13.4) | Anastomotic stenosis (0–11.1) | Insufficient colon length |
| Shorter operating time and length of stay | Electrolyte 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 avoided | Urinary 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 | |||
