Results

High-output syndrome developed in 44/195 eligible patients (22.6%).Multivariable analysis revealed that neoadjuvant(chemo)radiotherapy, postoperative complications, postoperative maximal white blood cell, and postoperative maximal C-reactive protein 10 mgdl were independently associated with high-output syndrome. High-output syndrome was associated with increased renal dysfunction at the time of ostomy closure, but not with nutritional imbalance or electrolyte abnormalities.
