The incidence of AL was 7.3%. The clinical course of patients with AL showed that in 21% of leaks, the drain indicated leakage; in the remaining patients, computed tomography or laparotomy resulted equally often in the detection of AL. In 50% of patients with AL, a Hartmann operation was needed. The incidence of AL was significantly higher in patients with pulmonary comorbidity (22.6% leakage), patients taking corticosteroids as long-term medication (50% leakage), and patients taking corticosteroids perioperatively (19% leakage). Perioperative corticosteroids were prescribed in 8% of patients for the prevention of postoperative pulmonary complications.Conclusions  We found a significantly increased incidence of AL in patients treated with long-term corticosteroids and perioperative corticosteroids for pulmonary comorbidity. Therefore, we recommend that in this patient category, anastomoses should be protected by a diverting stoma or a Hartmann procedure should be considered to avoid AL.Trial Registration  trialregister.nl Identifier: NTR1258
