[A Study of Bridge to Surgery for Obstructive Colorectal Cancer].

The JSCCR Guidelines 2024 for the Treatment of Colorectal Cancer weakly recommend stent treatment as a bridge to surgery(BTS)for obstructive colorectal cancer in the context of curative surgical resection. We retrospectively examined the backgrounds and treatment outcomes of 10 patients with obstructive colorectal cancer who underwent stent placement for BTS at our hospital between April 2020 and October 2024. The study included 4 males and 6 females, with a median age of 82 years. The lesions were located in the ascending/transverse/descending/sigmoid colon in 2/3/3/2 cases, respectively. CROSS was 0/1/2/3/4 in 2/2/5/1/0 cases. After stent placement, all cases improved to CROSS 3 or higher, and no complications due to stent placement were observed. The median interval time between stent placement and surgery was 32 days. Two patients underwent open surgery, and 8 patients underwent laparoscopic surgery(3 of which were converted to open surgery). No serious postoperative complications were observed. No progression of disease was observed during the BTS period. These results suggest that stent treatment for the purpose of BTS in obstructive colorectal cancer is useful and can be performed safely.
