Should a Loop Ileostomy Closure in Rectal Cancer Patients Be Done During or After Adjuvant Chemotherapy?

Background And Objective: The influence of ileostomy closure timing on surgical and oncologic outcome was investigated in patients with locally advanced rectal cancer receiving adjuvant chemotherapy after low anterior resection.

Methods: Consecutive patients diagnosed with T3-4/N+ rectal cancer, treated by neoadjuvant chemoradiation and low anterior resection during 2000-2012 were retrospectively evaluated. Patients undergoing closure during adjuvant chemotherapy (Group A) were compared to patients undergoing closure after completing chemotherapy (Group B).

Results: A total of the 165 patients met inclusion criteria, of whom 104 received adjuvant chemotherapy (25 in Group A and 79 in Group B). The pathologic stage was higher in Group B (P = 0.015). The rates of postoperative complications were similar (16% for Group A and 15% for Group B, P = 0.88), as was hospital stay (mean 5.78 days for Group A and 6.25 days for Group B, P = 0.7). There was no significant difference in recurrence rate and overall survival between the groups.

Conclusions: Referral to ileostomy closure in relation to adjuvant chemotherapy is influenced by pathologic stage. Early referral appears to be reserved to a small number of patients with lower pathologic stage. Timing of ileostomy closure does not change short- or long-term results.
