To reduce the occurrence of colonic perforation by colonic self-expandable metallic stenting, we analyzed our experience. A retrospective review was conducted of 27 consecutive patients who underwent stenting at our center from June 2016.
Twenty-four cases of stenosis were caused by colorectal cancer, and resection of the primary tumor was performed after stenting in 17 of the 24 cases. All stents were 22mm in diameter and consisted of Niti-S and HANAROSTENT. Stenting improved "ColoRectal Obstruction Scoring System (CROSS) " score in 25 of the 26 cases (96%). In one case, it did not improve because hard stools were stacked. No stent migrated.
Perforation occurred in 3 cases (11%). One case suggested that stenting over the normal rectum may not be preferable in patients with sigmoid colon stenosis. Another case suggested that the possibility of perforation should always be kept in mind especially in peritoneal carcinomatosis patients. The third case suggested that a long period of obstruction before stenting may lead to perforation.
