Aim: In the Netherlands, a selective policy of faecal diversion after rectal cancer surgery is generally applied. This study aimed to evaluate the timing, type, and short-term outcomes of reoperation for anastomotic leakage after primary rectal cancer resection stratified for a defunctioning stoma.
Method: Data of all patients who underwent primary rectal cancer surgery with primary anastomosis from 2013-2019 were extracted from the Dutch ColoRectal Audit. Primary outcomes were new stoma construction, mortality, ICU admission, prolonged hospital stay, and readmission.
Results: In total, 10,772 rectal cancer patients who underwent surgery with primary anastomosis were included, of whom 46.6% received a primary defunctioning stoma. The reintervention rate for anastomotic leakage was 8.2% and 11.6% for patients with and without a defunctioning stoma (p < 0.001). Reintervention consisted of reoperation in 44.0% and 85.3% (p < 0.001), with a median time interval from primary resection to reoperation of seven days (IQR 4-14) vs. five days (IQR 3-13), respectively. In the presence of a defunctioning stoma, early reoperation (<5 days; n = 47) was associated with significantly more end-colostomy construction (51% vs. 33%) and ICU admission (66% vs. 38%) than late reoperation (≥5 days; n = 127). Without defunctioning stoma, early reoperation (n = 252) was associated with significantly higher mortality (4% vs. 1%), and more ICU admissions (52% vs.34%) than late reoperation (n = 302).
Conclusions: Early reoperations after rectal cancer resection are associated with worse outcomes reflected by a more frequent ICU admission in general, more colostomy construction, and higher mortality in patients with primary defunctioned and nondefunctioned anastomosis.
