Stent management of a benign anastomotic stricture and SEMS displacement. In a patient with a history of resected sigmoid CRC, plain radiographic (a) shows LBO (*). Fluoroscopic contrast enema (b) and endoscopy confirm a tight stricture at the site of colorectal anastomosis (arrowhead in b) located 12 cm above the anal verge. Noncontrast CT (c, d) confirms fluid-filled dilated colon (*), without abnormal mural thickening or extraluminal mass at the anastomosis (arrowheads). A SEMS (thick arrows) was placed through the stricture (e). Unfortunately, LBO (* in f) ultimately recurred after SEMS displacement
