Abstract Aim Self‐expandable metallic stent (SEMS) placement for obstructive colon cancer is widely performed as a bridge to surgery (BTS) procedure before resection. This study aimed to investigate the surgical and oncological results of laparoscopic elective surgery with or without SEMS placement to assess the efficacy of SEMS placement as a BTS. Methods We retrospectively analyzed consecutive patients with stage II, III, and IV left‐sided colon cancer who underwent elective laparoscopic resection between 2013 and 2019. All patients were divided into two groups: with and without SEMS placement. Results The SEMS group included 24 patients, whereas the non‐SEMS group included 86 patients. The serum hemoglobin and albumin levels were lower ( P = .049, P = .03), and the serum leukocyte and C‐reactive protein levels were higher ( P < .0001, P = .022) in the SEMS group. The tumor diameter and tumor circumferential rate were higher in the SEMS group (both P < .0001). No significant differences were observed in operation time, blood loss, postoperative complications, or postoperative hospital stay. After 1:1 propensity score matching, 15 patients in the SEMS group were compared with 15 patients in the non‐SEMS group. The 3‐year overall survival rates of the SEMS and non‐SEMS groups were 87.5% and 88.9%, respectively ( P = .97). The 3‐year recurrence‐free survival rates of the SEMS and non‐SEMS groups were 58.2% and 81.7%, respectively ( P = .233). No significant difference was found in the sites of recurrence. Conclusion The perioperative and long‐term outcomes of SEMS placement as a BTS before laparoscopic resection could be acceptable compared with other elective laparoscopic operations without SEMS placement.
