Purpose
To assess the benefit of placing a self-expandable metallic stent (SEMS) as a bridge to surgery for obstructive colorectal cancer (OCRC) according to the tumor site.
Methods
The subjects of this retrospective multicenter cohort study were 201 patients with OCRC, but without initial bowel perforation, who were treated either with a self-expandable metallic stent (SEMS) as a bridge to surgery (n = 109) or with primary surgery (PS; n = 92) between 2014 and 2016. The cohort consisted of 68 patients with right-sided and 133 left-sided OCRC. We evaluated the short-term surgical outcomes for each side.
Results
The SEMS group of patients with left-sided OCRC had significantly higher rates of primary resection, primary resection with anastomosis, stoma-free surgery, and laparoscopic surgery than the PS group of patients with left-sided OCRC. In contrast, the SEMS group of patients with right-sided OCRC had only a significantly higher rate of laparoscopic surgery than the PS group of patients with right-sided OCRC, but they had a longer overall hospital stay. There were no significant differences between the two treatment groups in the rates of morbidity or mortality, for either right-sided or left-sided OCRC.
Conclusion
The benefit of a SEMS as a bridge to surgery may be less for right-sided than for left-sided obstructions in colon cancer patients.
