Background A bridge to surgery (BTS) using self‐expandable metallic stents (SEMSs) is becoming the primary treatment for obstructive colorectal cancer (OCRC). In Japan, intestinal decompression was usually performed using decompression tubes (DTs). However, few reports have compared the outcomes of SEMS and DTs as BTS. Therefore, we compared the treatment outcomes of SEMS and DTs for OCRC. Methods Data of 80 patients who underwent radical resection after endoscopic decompression for stage II or III OCRC between 2007 and 2021 were retrospectively analyzed. Patients were divided into two groups based on whether they received SEMS (n = 53) or DTs (n = 27). Results The clinical success rate of decompression was 96.2% and 88.9% in the SEMS and DT groups, respectively. Additionally, 96.2% of patients who received SEMS were able to resume their routine diet without stricture symptoms. The rate of stoma construction and incidence of postoperative complications were lower in the SEMS group (p < 0.005 and p < 0.01, respectively). The 3‐year relapse‐free survival rates were 71.9% and 51.2% in the SEMS and DT groups, respectively, which were not significantly different (p = 0.10). Conclusion BTS using SEMS might be an adequate treatment for stage II or III OCRC regardless of tumor location owing to the comparable oncological outcomes with DT and low perioperative complication rate.
