Abstract

Diverting loop ileostomy has become routine in low anterior resection (LAR) for rectal cancer. The optimal time for stoma reversal is controversial. The aim of the present study was to compare the results after planned early (within 8-12 days) versus late (> 3 months) stoma reversal. The primary outcomes were morbidity and mortality, as measured by the Comprehensive Complication Index (CCI) within 30 days after stoma reversal, and the secondary outcomes were morbidity and mortality within 90 days after LAR. This was a multicentre trial including all patients scheduled for anterior low resection for rectal cancer with curative intent. Inclusion period was from April 2011 to December 2018. All patients were randomized 1:1 prior to surgery. Among 257 consecutive and eligible patients, a total of 214 patients were randomized: 107 patients to early stoma reversal and 107 to late reversal. A total of 68 patients were excluded for various reasons, and 146 patients completed the study, with 77 in the early reversal group and 69 in the late reversal group. The patients were asked to complete the Gastrointestinal Quality of Life Index before surgery (baseline) and at 6 and 12 months after LAR. Ostomy-related complications were evaluated by dedicated ostomy staff using the validated DET score. ClinicalTrials Identifier: NCT01865071. Fifty-three patients (69%) in the early reversal group and 60 patients (87%) in the late reversal group received the intended treatment. There were no significant differences in CCI within 90 days after index surgery with the LAR and within 30 days after stoma reversal between the two groups. There were no differences in patient-reported quality of life but significantly more stoma-related complications in the late reversal group. A total of 5 patients experienced anastomotic leakage (AL) after stoma reversal, 4 in the early reversal group and one in the late reversal group. Early and late stoma reversal showed similar outcomes in terms of overall complications and quality of life. The risk of developing anastomotic leakage after early ostomy reversal is a concern.
