Self-expanding Metallic Stent Placement Followed by Neoadjuvant Chemotherapy and Scheduled Surgery for Treatment of Obstructing Left-sided Colonic Cancer

Stoma is reported to be frequent in self-expanding metallic stent (SEMS) treated patients with obstructing left-sided colon cancer than in those with non-obstructing surgery. Retrospective study reported worse overall survival with SEMS and elective surgery than with emergency surgery in patients with left-sided malignant colon obstruction. In practice, intestinal wall edema following stent placement increases the difficulty of surgery, and this could be a major problem if the interval between stent insertion and surgery is short (1-2 weeks). The patients with obstructing left-sided colon cancer received SEMS treatment, and the recevied neoadjuvant chemotherapy prior to elective surgery.
