An alternative to ACAI is delayed coloanal anastomosis without reservoir (ACAD). Based on retrospective experiences, we form the hypothesis that ACAD offers a much lower rate of fistula (<5%) and allows diminution of preventive stoma derivation practice. Morbidity and mortality are reduced, and patient's quality of life greatly improved. Direct costs (consumables intraoperative, hospitalization, stoma complications) and indirect (pocket-fitting stoma) are greatly reduced.
