What are the factors predictive of postoperative complications in patients with colorectal cancer undergoing stenting as a bridge to surgery?

Objective Using a self‐expanding metal stent as a bridge to surgery (BTS) is considered a reasonable strategy for patients with acute malignant large bowel obstruction. Since postoperative complications have a negative impact on patient survival, we aim to clarify the predictors of complications in patients undergoing BTS using a self‐expanding metal stent. Methods We conducted a retrospective review of 61 patients with colorectal cancer (CRC) who underwent stenting as a BTS at our institution. We analyzed the association of postoperative complications with clinicopathologic, surgical, and patient factors, and with the prestenting or preoperative laboratory data. Results Both postoperative complications in general and severe complications were significantly associated with a longer stenotic‐section length (p = 0.007 and p = 0.003), lower preoperative hemoglobin levels (p
