Outcomes of Bridge to Surgery for Obstructive Colorectal Cancer after Metallic Stent Placement in Our Hospital

: Recently, the endoscopic placement of self-expanding metallicstents (SEMSs)has become widespread for the treatment of acute malignant colorectal obstruction. This study was designed to evaluate the clinical outcomes of 22 patients with obstructive colorectal cancer who underwent SEMS placement as a bridge to surgery(BTS)from January 2012 to December 2015. The subjects comprised 15 men and 7 women with a mean age of 68.1 years. Placement and decompression were successfully achieved in all cases. No serious complications arose from the placement. After excluding 3 patients for whom preoperative chemotherapy or treatment for another disease was prioritized, the mean interval to surgery for the remaining 19 patients was 18.2 days. Operative anastomosis was performed in all patients except those who had tandem lesions. Although postoperative complications including minor leakage(n=1), surgical site infection(n=1), and ileus(n=1)were observed, the course was effective in most patients. Bridge to surgery is a relatively easy, safe, and effective method for the treatment of obstructive colorectal cancer that enables preoperative intestinal decompression and one-stage resection, preventing stoma creation.
