Figure 1 Flowchart depicting patient selection. ASA: American Society of Anesthesiologists; FAP: Familial adenomatous polyposis.

Figure 2 Imaging examination. A: Computed tomography image showing proximal colonic dilation with a transition point and distal collapse. The orange arrow shows the tumor location; B: Abdominal radiography showed that the stent expanded successfully and the relief of the bowel obstruction; C: The colonic stent was deployed endoscopically.

Figure 3 Kaplan-Meier curves. A: Kaplan-Meier curves showing the overall survival in the bridge to surgery group and emergency resection group (P = 0.34); B: Kaplan-Meier curves showing the progression-free survival in the bridge to surgery group and emergency resection group (P = 0.21). BTS: Bridge to surgery; ER: Emergency resection.
