Background: Self-expanding metallic stents (SEMS) insertion is an alternative to emergency surgery in malignant colonic obstruction. However, the long-term oncological outcome of stents as a bridge to surgery is limited and controversial. Objectives: To determine the long-term oncological outcome of stents as a bridge to surgery. Methods: Data of patients who underwent emergency surgery and endoscopic stent insertion as a bridge to surgery due to obstructing colonic cancer at Soroka Medical Center during a 14 year period were collected retrospectively. Preoperative data, tumor staging, and oncological outcomes in terms of local recurrence, metastatic spread, and overall survival of the patients were compared. Results: Sixty-four patients (56% female, mean age 72 years) were included in the study: 43 (67%) following emergency surgery, 21 stent inserted prior to surgery. A stent was inserted within 24–48 hours of hospital admission. The mean time between SEMS insertion and surgery was 15 days (range 0–30). Most of the patients had stage II (41%) and stage III (34%) colon cancer. There was no difference in tumor staging and localization between groups. There was no significant difference in disease recurrence between SEMS and surgery groups, 24% and 32%, respectively. Disease-free survival rates were similar between the SEMS group (23.8%) and surgery group (22%). Four year and overall survival rates were 52.4% vs. 47.6%, 33.3% vs. 39.5%, respectively. Conclusions: SEMS as a bridge to surgery in patients with obstructing colon cancer provide an equivalent long-term oncological outcome to surgery alone.
