Colonic stenting has been suggested as an acceptable therapeutic option for the palliation of malignant colorectal obstruction or to achieve bowel decompression and preparation. It is effective as a bridge to surgery that is useful as an option to avoid emergency colostomy. However, it is associated with complications such as intestinal perforation, stent migration, bleeding, and failure of bowel decompression. Of all the complications, intestinal perforation and failure of bowel decompression are most serious and require surgical treatment. Here we report a case of abdominal compartment syndrome after stent insertion for obstructive colon cancer. The main causative factors for abdominal compartment syndrome were bowel distension associated with endoscopic gas inflation and failure to achieve bowel decompression.
